BUFFALO, NY — August 1, 2025 — A new #research paper featured on the #cover of Volume 17, Issue 7 of Aging (Aging-US) was #published on July 25, 2025, titled “Systemic factors in young human serum influence in vitro responses of human skin and bone marrow-derived blood cells in a microphysiological co-culture system.” The study, led by first author Johanna Ritter and corresponding author Elke Grönniger from Beiersdorf AG, Research and Development Hamburg, shows that components in young human blood serum can help restore youthful properties to skin, but only when bone marrow cells are also present. This discovery highlights the role of bone marrow in supporting skin health and may allow for novel approaches aimed at slowing or reversing visible signs of aging. The research explored how factors present in blood serum, already known to influence aging in animal studies, act on human cells. Using an advanced system that mimics human circulation, the researchers connected a 3D skin model with a 3D bone marrow model. They found that young human serum alone was not enough to rejuvenate skin. However, when bone marrow cells were present, these serum factors changed the activity of those cells, which then secreted proteins that rejuvenated skin tissue. “Interestingly, we detected a significant increase in Ki67 positive cells in the dynamic skin model co-cultured with BM model and young serum compared to the model co-cultured with BM and old serum, indicating an improved regenerative capacity of the tissue.” Detailed analysis indicated that young serum stimulated the bone marrow to produce a group of 55 proteins, with 7 of them demonstrating the ability to boost cell renewal, collagen production, and other features associated with youthful skin. These proteins included factors that improved energy production in cells and reduced signs of cellular aging. Without the interaction between skin and bone marrow cells, these rejuvenating effects did not occur. This finding explains why earlier experiments in mice, where young and old animals shared a blood supply, showed rejuvenation across organs. It suggests that bone marrow-derived cells are critical messengers that transform signals from blood into effects on other tissues, including the skin. While these results are preclinical and not from human trials, they offer a starting point for new strategies in regenerative medicine and skin care. By identifying specific proteins that may carry rejuvenating signals, the study points to a new way to address age-related changes. Researchers emphasize that further studies will be needed to confirm these effects in humans and to test how these proteins can be safely and effectively applied in future therapies. Overall, this research is an important step in understanding how young blood serum factors influence human tissue and could guide the development of novel methods to maintain healthier skin as people age.

BUFFALO, NY — July 30, 2025 — A new #research paper was #published in Aging (Aging-US) on July 23, 2025, titled “Second generation DNA methylation age predicts cognitive change in midlife: the moderating role of childhood socioeconomic status.” In this study, led by Sophie A. Bell and Eric Turkheimer from the University of Virginia, researchers investigated how biological aging, measured through DNA methylation, is connected to changes in thinking skills during midlife and whether childhood socioeconomic status influences this relationship. Biological age provides a picture of how the body is aging that goes beyond simply counting years. In this study, researchers used both first- and second-generation DNA methylation clocks—tools that track chemical changes in DNA as markers of aging. GrimAge and PhenoAge, the second-generation clocks designed to reflect broader health and aging processes, were more accurate at predicting long-term changes in Intelligence Quotient (IQ) than the first-generation models that only estimated chronological age. The study analyzed 287 participants from the Louisville Twin Study, which is a long-term project that has followed twins from childhood into midlife. “DNAmAge was estimated with five commonly used algorithms, or epigenetic clocks (Horvath, Horvath Skin and Blood, GrimAge, and PhenoAge).” The results showed that twins with more rapid epigenetic aging had a larger drop in IQ scores. This pattern remained even after considering genetic background and early family environment, made possible by the twin-based design. Importantly, the relationship was strongest in twins who had grown up in families with lower socioeconomic status. This finding suggests that early-life disadvantage may make individuals more vulnerable to the effects of biological aging on brain health. This research adds knowledge to earlier work showing that childhood poverty can influence long-term health. It also highlights the value of second-generation epigenetic clocks as early indicators of brain aging. Unlike the first generation of clocks, these newer tools capture broader biological changes such as inflammation, disease risk, and behaviors like smoking. Although smoking partly explained the results because it strongly influences DNA methylation, it did not fully account for the association between accelerated biological aging and cognitive decline. This suggests that both life experiences and lifestyle factors shape body and brain aging. By combining decades of developmental data with a genetically informed twin design, the study provides new evidence that biological aging, especially when shaped by childhood adversity, is a key factor in midlife cognitive decline. These findings may inform early health strategies that consider both social and biological risks and support the use of second-generation methylation clocks to predict age-related cognitive changes.

BUFFALO, NY - July 29, 2025 – A new #research paper was #published in Volume 16 of Oncotarget on July 25, 2025, titled “Comprehensive genomic profiling of over 10,000 advanced solid tumors.” In this study, led by Jean-Paul De La O from Exact Sciences Corporation, researchers analyzed data from over 10,000 solid tumor samples from patients with advanced cancer and found that more than 90 percent contained genetic changes that could guide treatment. This work demonstrates the growing impact of large-scale tumor DNA and RNA testing on patient care. The researchers retrospectively analyzed OncoExTra assay information for 31 types of cancer, including breast, colorectal, prostate, lung, and ovarian cancers. Their analysis revealed that nearly a third of patients had alterations associated with approved drugs for their specific cancer, while another third had changes linked to therapies approved for other cancers. These results show that detailed genetic profiling could expand treatment choices. “Biomarkers associated with on- or off-label FDA-approved therapies were detected in 29.2% and 28.0% of samples, respectively.” Another relevant discovery was that many important mutations occurred at very low levels, which are often missed by simpler tests. By using a broad and highly sensitive approach, the scientists were able to identify these rare mutations. They also reported that 7.5 percent of samples carried gene fusions, unusual genetic events that can drive cancer growth. Such findings can be critical in selecting therapies that specifically target these abnormalities. The study also highlighted the value of RNA sequencing in detecting fusion events that traditional DNA tests might miss. Prostate cancer and certain sarcomas showed particularly high rates of these fusion alterations. This type of information can refine cancer diagnosis and improve therapy planning. In addition, the researchers identified changes in several major cancer-related pathways, including those that control cell growth, DNA repair, and immune system response. Alterations in these pathways can point to newer treatment options, such as immunotherapy or drugs designed to block specific cell signals. Overall, this study shows that comprehensive genomic profiling can guide more personalized cancer care by identifying mutations, gene fusions, and other molecular patterns. Advanced testing methods like the OncoExTra assay reveal treatment opportunities even in advanced cancers, ensuring that subtle but important genetic changes are detected.

A New Way to Target Resistant Prostate Cancer Cells

Prostate cancer is the second most diagnosed cancer among men worldwide and remains a leading cause of cancer-related death. While early forms of the disease can usually be treated successfully, advanced cases remain a major challenge. Scientists have now discovered a new potential way to slow the growth of advanced, treatment-resistant prostate cancer. These results were recently published in Volume 16 of Oncotarget by researchers from the University of Cincinnati College of Medicine. Understanding Advanced Prostate Cancer Early-stage prostate cancer can often be treated successfully. Most treatments work by lowering testosterone levels or blocking the hormone from activating the androgen receptor (AR), which drives cancer growth. In some patients, however, the disease progresses to castration-resistant prostate cancer (CRPC). Even with drastic reductions in testosterone levels, the tumors continue to grow at this stage. CRPC is much more difficult to treat, and current therapies such as hormone blockers or chemotherapy typically extend life by only a few months. One reason for this resistance is that cancer cells often switch to a different form of the androgen receptor called AR-V7. This variant remains permanently active, even without testosterone, making hormone-based drugs less effective. Because of this, new treatment strategies that work independently of hormone levels are needed. The Study: Targeting a New Weakness in Prostate Cancer Cells In the study titled “Targeting PCNA/AR interaction inhibits AR-mediated signaling in castration resistant prostate cancer cells,” researchers Shan Lu and Zhongyun Dong from the University of Cincinnati College of Medicine investigated a new way to block CRPC growth.

BUFFALO, NY – July 24, 2025 – A new #casereport was #published in Volume 16 of Oncotarget on July 23, 2025, titled “Extracorporeal blood filtration leading to tumor growth arrest and reduced analgesic requirements in Stage IV poorly differentiated pancreatic adenocarcinoma: A case report.” In this report, Susanna Ulahannan from the University of Oklahoma Health Sciences Center and colleagues describe the use of extracorporeal blood filtration in a patient with metastatic pancreatic cancer. The patient experienced clinical improvement, reduced pain, and no signs of new tumor growth over 12 months of follow-up. Metastatic pancreatic cancer is difficult to treat and is often diagnosed at an advanced stage. In this case, a 51-year-old woman with stage IV poorly differentiated adenocarcinoma chose not to undergo standard chemotherapy. Instead, she received extracorporeal blood filtration with the Seraph® 100 device, which is designed to remove circulating tumor cells (CTCs) from the bloodstream. CTCs are thought to contribute to the spread of cancer to other organs. “Circulating tumor cells (CTC's) are tumor cells that are shed from the primary tumor and travel via blood or lymphatic system to form micro metastases in distant organs under a suitable environment.“ The patient received between nine and twelve treatments over the course of a year. These treatments were performed both abroad, where the device is approved for this use, and under a clinical protocol in the United States. Medical imaging showed that her disease remained stable, with no new metastases detected. She also reported improvements in appetite, energy levels, and pain control. Her opioid use was reduced by 90%. Blood samples confirmed a drop in CTC levels after treatment. This observation supports the idea that removing CTCs might help limit cancer progression in some patients. However, given that this is a single case report, larger clinical studies are needed to evaluate the effectiveness of this approach. The mechanism behind the patient's pain relief is not fully understood. Authors suggest that it may be related to the reduction of tumor cells or inflammatory molecules in the blood. Researchers noted that pro-inflammatory cytokines, known to influence pain, could also have been affected by the filtration process. This is the first documented case of stable disease and reduced symptoms following CTC filtration in advanced pancreatic cancer. While these findings should not be generalized, they highlight an approach outside standard protocols that should be further explored in clinical research. Future studies will be needed to determine whether this method can contribute to symptom management or disease control in other patients with metastatic pancreatic cancer.

BUFFALO, NY — July 23, 2025 — A new #research paper was #published in Aging (Aging-US) Volume 17, Issue 6, on June 16, 2025, titled “rDNA copy number variation and methylation from birth to sexual maturity.” In this study, led by first authors Alina Michler and Sarah Kießling along with corresponding author Thomas Haaf from Julius Maximilians University in Germany, researchers explored how ribosomal DNA (rDNA) copy number and methylation change from infancy to adolescence. They discovered that the epigenetic changes often associated with aging in adults do not occur before sexual maturity. This finding offers new insights into when the biological aging process truly begins. Ribosomal DNA plays a critical role in producing proteins essential for cell survival. The researchers analyzed blood samples from 280 individuals, ranging from newborns to 18 years of age, including healthy individuals and those with developmental delays. They measured the number of rDNA copies and examined how genes are switched on or off through methylation, a chemical modification of DNA. The results showed that while adults experience a gradual loss of active rDNA copies and increased methylation—a hallmark of aging—these changes were absent in children and teenagers. In fact, during childhood and adolescence, the number of active, unmethylated rDNA copies slightly increased. These findings support the long-debated idea that biological aging begins only after the body reaches reproductive maturity. Until that point, cells appear to actively maintain rDNA in a youthful state, ensuring that protein production remains efficient. This may help explain why children and teenagers are better at resisting many age-related diseases and why their cells recover more easily from stress. The study also shows that changes in rDNA copy numbers are not associated with unexplained developmental delays. This suggests these epigenetic processes are probably not involved in early-life syndromes. The findings highlight how the body works to preserve genetic stability during childhood and raise important questions about what triggers the shift to aging-related changes after puberty. “Collectively our data suggest that the rDNA hypomethylation state is actively maintained in somatic tissues of young individuals.” The insights gained from this research expand the understanding of the molecular clock of aging. They suggest potential new ways to delay aging processes by exploring how youthful rDNA methylation patterns are maintained. As scientists continue to investigate these mechanisms, the study provides a clear foundation for future research aimed at extending cellular health beyond adolescence.

BUFFALO, NY – July 22, 2025 – A new #research paper was #published in Volume 16 of Oncotarget on July 21, 2025, titled “Statins exhibit anti-tumor potential by modulating Wnt/β-catenin signaling in colorectal cancer.” In this work, led by first author Sneha Tripathi from the Indian Institute of Science Education and Research and corresponding author Sanjeev Galande from the Center of Excellence in Epigenetics at Shiv Nadar University, researchers discovered that statins, widely used to lower cholesterol, may also suppress colorectal cancer growth. This finding highlights a potential new role for these common drugs in cancer prevention and therapy. Colorectal cancer is one of the leading causes of cancer-related deaths worldwide, and new strategies are urgently needed to improve treatment results. Statins, originally developed to lower cholesterol levels, have gained attention for their possible anti-cancer properties. The study investigated how statins affect the Wnt/β-catenin signaling pathway, a critical driver in colorectal cancer development and progression. The researchers discovered that statins disrupt the Wnt/β-catenin signaling pathway, leading to lower levels of tumor-promoting proteins and to cancer-suppressing cellular behaviors. Experiments in both colorectal cell cultures and mouse models confirmed that statins reduced tumor growth without causing noticeable side effects. This study further revealed that statins downregulate SATB1, a protein linked to aggressive tumor behavior, while increasing SATB2, a protein with tumor-suppressing effects. These changes made the cancer cells less able to grow and spread. “This reciprocal regulation shifts cellular phenotypes between epithelial and mesenchymal states in 3D spheroid models.” Overall, the findings suggest that statins could be repurposed to complement existing colorectal cancer treatments or even be used in preventive strategies for high-risk individuals. By targeting the molecular machinery that drives colorectal tumor development, statins offer a promising, accessible, and well-understood option for further research in cancer therapy. This research opens the door to larger clinical studies to explore how best to integrate statins into cancer care. If successful, this approach could provide a cost-effective strategy for reducing the global burden of colorectal cancer, which remains a significant health challenge.

BUFFALO, NY — July 21, 2025 — A new #research paper was #published in Aging (Aging-US) Volume 17, Issue 6, on June 27, 2025, titled “Enhancing oocyte activation in women with ovarian failure: clinical outcomes of the Stem Cell Regenera study using G-CSF mobilization of peripheral blood stem cells and intraovarian injection of stem cell factor-enriched platelet rich plasma in real-world-practice.” This study, led by Amparo Santamaria with co-authors Ana Ballester and Manuel Muñoz from IVI Clinics Alicante, evaluates the effectiveness and safety of a regenerative treatment that may enable women with ovarian failure to regain the ability to produce viable eggs. The approach combines stem cell mobilization and enriched plasma injections into the ovaries to stimulate follicle growth. It provides an alternative for patients experiencing infertility due to poor ovarian response, diminished ovarian reserve, or premature ovarian insufficiency. Researchers evaluated the Stem Cell Regenera treatment in 145 women, aged 26 to 44 years, who had not responded to conventional fertility therapies. The procedure involved mobilizing the body's own stem cells using granulocyte colony-stimulating factor (G-CSF), followed by an injection of platelet-rich plasma enriched with stem cell factors directly into the ovaries. This method was designed to activate dormant follicles and promote ovarian regeneration. Nearly 70% of participants demonstrated oocyte activation, defined as increased follicle growth or a rise in key hormone levels. Approximately 7% achieved spontaneous pregnancies, and 14% conceived through in vitro fertilization (IVF) after treatment. These results indicate that the therapy stimulates ovarian activity and may increase the chances of conception in selected patients. “The primary outcome measures were the rate of oocyte activation, leukocytes and stem cell count, and pregnancy rates.” No severe adverse effects were reported. Most participants tolerated the treatment well, with only mild and transient symptoms such as headaches or fatigue. The use of the patient's own cells minimized the risk of immune reactions and helped ensure the treatment was safe. The findings provide evidence of effectiveness and safety for the Stem Cell Regenera protocol in a clinical setting. While the study was retrospective observational, the outcomes support further investigation through larger controlled trials to confirm long-term benefits and identify which patient populations may gain the greatest benefit from this approach. This research contributes to the growing field of regenerative medicine in reproductive health, offering clinicians additional tools to address infertility in women with complex ovarian conditions.

A new #study published recently in Volume 17, Issue 6, examines a novel treatment for women with ovarian failure. Researchers from IVI Clinics Alicante in Spain investigated a procedure called Stem Cell Regenera, which uses the body's own stem cells and platelet-rich plasma to activate dormant follicles in the ovaries. This innovative protocol could expand options for patients with ovarian failure who have not responded to conventional fertility therapies. Understanding Ovarian Failure Ovarian failure affects women's ability to conceive by reducing the quantity and quality of eggs in the ovaries. Conditions like Poor Ovarian Response, Diminished Ovarian Reserve, and Premature Ovarian Insufficiency are key reasons for infertility and make it hard to use assisted reproduction methods like in vitro fertilization (IVF). Standard fertility treatments often fail to improve outcomes for these patients, leaving donor eggs as the primary alternative. However, recent advances in regenerative medicine have raised the possibility of restoring ovarian function using cellular therapies. Emerging research suggests that the right biological conditions could reactivate dormant follicles within the ovaries, potentially helping patients to use their eggs.

BUFFALO, NY - July 18, 2025 – A new #editorial was #published in Volume 16 of Oncotarget on July 16, 2025, titled “microRNAs in soft tissue sarcoma: State of the art and barriers to translation.” In this article, Elizaveta K. Titerina, Alessandro La Ferlita, and Joal D. Beane from Ohio State University discuss the role of microRNAs in soft tissue sarcomas (STS), a rare and diverse group of cancers that begin in connective tissues, like bone or fat. The authors explain how these small molecules regulate cancer-related processes and highlight their potential as non-invasive biomarkers for diagnosis and monitoring. They also outline the main challenges that need to be addressed before microRNA-based strategies can be used in clinical settings. Soft tissue sarcomas include over 50 subtypes, making precise diagnosis and effective treatment difficult. The editorial describes how microRNAs influence cancer growth, spread, and response to therapies. Because microRNAs are stable in body fluids like blood and saliva, they could be used for early detection and to help guide treatment decisions. Such as, certain groups of microRNAs are linked to how patients respond to specific drugs, showing their potential as tools for precision medicine. “For example, miR-17-92 and miR-106b-25 clusters have been associated with sensitivity or resistance to eribulin in STS.” The authors also explain that microRNAs could help distinguish between tumor types that are often difficult to differentiate, such as benign lipomas and malignant liposarcomas. Recognizing these differences is crucial for guiding treatment decisions. Specific patterns of microRNA expression in blood samples may enable clinicians to make quicker and more reliable diagnoses without the need for invasive procedures. Beyond their diagnostic role, microRNAs are also being explored as therapeutic tools, but applying microRNA-based therapies to patients remains challenging. These molecules can act as either cancer promoters or suppressors, depending on the environment, which complicates the development of safe and targeted treatments. However, new delivery methods such as lipid nanoparticles show promise in improving precision and safety. Overall, microRNAs are emerging as an important focus in STS research, offering new possibilities for advancing diagnosis, prognosis, and treatment. As researchers continue to address the current challenges, these small molecules could become valuable tools in improving cancer care.

BUFFALO, NY - July 16, 2025 – A new #research paper was #published in Volume 16 of Oncotarget on July 9, 2025, titled “A novel anti-human CD25 mAb with preferential reactivity to activated T regulatory cells depletes them from the tumor microenvironment.” In this study, researchers from the National Institute of Allergy and Infectious Diseases, led by first author Maja Buszko and corresponding author Ethan M. Shevach, discovered a new monoclonal antibody that selectively targets a subset of immune cells called regulatory T cells (Tregs). These cells, while normally important for preventing autoimmunity, also can block the body's ability to fight cancer by suppressing anti-tumor immune responses. This discovery could lead to novel cancer therapies that strengthen the immune system's capacity to attack tumors. The researchers identified an anti-CD25 monoclonal antibody with several atypical properties and named it 2B010. To evaluate its effects, they used humanized mice, laboratory mice that are engineered to carry human immune cells, to closely mimic how human immune systems respond to cancer. The treatment of these mouse models with 2B010 significantly decreased the number of Tregs in tumors and boosted the activity of CD8+ T cells, which are essential for killing cancer cells. Importantly, 2B010 worked without disrupting other key immune functions. Unlike traditional Anti-CD25 antibodies, it did not interfere with interleukin-2 (IL-2) signaling, which is essential for the growth and activity of effector T cells that fight cancer. “2B010 also had no effect on IL-2 induced STAT5 phosphorylation or CD4+ T cell proliferation in vitro while both were blocked by Clone D1 further supporting the view that 2B010 does not recognize the IL-2 binding site.” This finding is especially significant because high levels of Tregs in tumors are associated with poor outcomes in many cancers. By specifically removing these cells, 2B010 may help overcome one of the main barriers to current immunotherapy approaches. Its ability to preserve IL-2 signaling could also make it safer and more effective when used alone or in combination with existing therapies such as immune checkpoint inhibitors. While the 2B010 antibody showed strong effects in reducing Tregs and boosting immune cell activity, the study did not observe changes in tumor size in these models. Researchers suggest this may be due to limitations in the preclinical systems used, such as the lack of tumor-specific T cells in humanized mice. Nevertheless, these findings demonstrate that 2B010 has a unique mechanism of action that could complement other cancer immunotherapies in future clinical trials. In conclusion, the development of 2B010 is a promising step toward selectively disrupting the immune suppressive environment in tumors. As researchers continue to refine and test this antibody, it could become a powerful tool for enhancing the effectiveness of cancer treatments and improving outcomes for patients.

BUFFALO, NY — July 15, 2025 — A new #research paper was #published in Aging (Aging-US) Volume 17, Issue 6, on June 5, 2025, titled “Senescence caused by telomerase inactivation in myeloid, mesenchymal, and endothelial cells has distinct effects on cancer progression.” In this study, first author Joseph Rupert, along with corresponding author Mikhail G. Kolonin and colleagues from The Brown Foundation Institute of Molecular Medicine for the Prevention of Human Diseases, McGovern Medical School, at The University of Texas Health Sciences Center at Houston, investigated how aging-related changes in different cell types affect cancer progression. By turning off telomerase in specific cell populations in mice, the researchers discovered that cell aging, or senescence, can slow primary tumor growth but also trigger unexpected effects. This work sheds light on the complex relationship between aging cells and cancer and may help guide future anti-cancer strategies. The team used genetically modified mice to deactivate telomerase, the enzyme that maintains chromosome ends, specifically in immune, connective tissue, and blood vessel cells. This caused these cells to enter a state of senescence, where they stop dividing and release inflammatory signals. The researchers then implanted breast, prostate, and pancreatic cancer cells into the mice and tracked how tumors developed. They found that when telomerase was inactivated in immune cells or connective tissue cells, tumors grew more slowly. However, these tumors showed signs of increased tissue damage and potential aggressiveness. Interestingly, when telomerase was turned off in endothelial cells, which cover blood vessels, tumors shrank and became poorly supplied with blood, leading to oxygen deprivation. In the case of pancreatic cancer cells, this low-oxygen environment made them more likely to spread to the liver, highlighting a potential risk of targeting these cells. “[…] this study shows that senescence and metabolic dysfunction resulting from telomerase inactivation in distinct cells in the tumor microenvironment have different effects on tumor growth and metastasizing of carcinomas.” This research provides important insights into how aging cells within the tumor microenvironment (TME) influence cancer behavior. While senescence in certain cell types can help suppress tumor growth, it may also create conditions that favor cancer metastasis. These findings highlight the need to consider cell type-specific effects when developing therapies that target senescent cells. By mapping how different cell populations contribute to cancer progression in aging tissues, this study opens the door for more precise approaches to prevent both tumor growth and spread.

This retrospective observational study was conducted from January 2023 to December 2024 at the IVIRMA Alicante Clinics in Spain. Women diagnosed with ovarian failure participated in the study, which involved mobilizing Hematopoietic Stem Cells from bone marrow into peripheral blood using granulocyte colony- stimulating factor (G-CSF). This was followed by an intraovarian injection of Stem Cell Factor- enriched Platelet Rich Plasma (SCFE-PRP). The primary outcome measures were the rate of oocyte activation, leukocytes and stem cell count, and pregnancy rates. Oocyte activation was defined as an increase in total Antral Follicle Count of three or more follicles after treatment and/or at least a 20% rise in Anti-Müllerian Hormone levels. Safety was assessed based on adverse effects. Pregnancy rates were evaluated for both spontaneous gestation and following in vitro fertilization (IVF) treatment. A total of 145 women participated: the overall activation rate was 68.28%, with 7.07% achieving spontaneous gestation and 14.14% achieving pregnancy following IVF. Mobilization of CD34+ cells was successful in all participants, with an average collection of 32.96 CD34+ cells/μl. No severe adverse effects were observed. The study concluded that the Stem Cell Regenera Treatment is effective and safe for oocyte activation in women with ovarian failure in real-world practice.

Scientists have uncovered a promising new strategy to weaken cancer cells' natural defense mechanisms, potentially making chemotherapy more effective. In a study published in Volume 16 of Oncotarget, researchers identified the protein PRDX1 as a key player in helping tumors resist treatment. By targeting this protein, they propose a novel way to combat aggressive, treatment-resistant cancers. Understanding Why Some Cancers Resist Treatment Chemotherapy works by damaging the DNA of cancer cells, forcing them to self-destruct. However, many cancers develop robust repair systems that fix this damage, allowing the tumor to survive and grow. A central component of this repair machinery is a protein called ATM, which acts like a first responder in the cell, detecting DNA damage and coordinating its repair. In ovarian cancer and other aggressive tumors, high levels of ATM have been associated with poor survival rates and resistance to chemotherapy. The Study: How PRDX1 Protects Cancer Cells The study, titled “PRDX1 protects ATM from arsenite-induced proteotoxicity and maintains its stability during DNA damage signaling,” was led by first author Reem Ali and corresponding author Dindial Ramotar from Hamad Bin Khalifa University in Qatar, in collaboration with researchers from the University of Nottingham in the UK.

BUFFALO, NY – July 14, 2025 – A new #research paper was #published in Volume 16 of Oncotarget on June 25, 2025, titled “Hypoxia induced lipid droplet accumulation promotes resistance to ferroptosis in prostate cancer.” In this study, researchers led by Shailender S. Chauhan and Noel A. Warfel from the University of Arizona discovered that prostate cancer cells survive treatment by storing fats in tiny cellular compartments when oxygen levels are low. This process makes the cancer cells less vulnerable to a type of cell death known as ferroptosis. The findings provide new insight into why prostate tumors often resist therapies and suggest potential strategies to improve treatment outcomes. This study focused on ferroptosis, a form of programmed cell death that relies on iron and lipid oxidation to destroy cancer cells. Researchers tested prostate cancer cells under normal and low oxygen conditions and found that hypoxia, or reduced oxygen levels, allowed cancer cells to build up lipid droplets (LD). These structures act as storage units for fats, shielding cancer cells from oxidative damage and preventing ferroptosis from occurring. The researchers found that this adaptation of prostate cancer cells made them less sensitive to ferroptosis-inducing drugs like Erastin and RSL3, even when these drugs were combined for a stronger effect. The team also reported that hypoxia caused significant changes in lipid metabolism, decreasing the availability of specific fatty acids that normally promote ferroptosis. “Transcriptomic analysis revealed that hypoxia significantly reduced the expression of genes related to incorporating polyunsaturated fatty acids into phospholipids (ACSL4, LPCAT3), and parallel lipidomic analysis demonstrated that hypoxia significantly decreased the levels of the ferroptosis-prone lipid class, phosphatidylethanolamine (PE) and increased production of neutral lipid species, cholesteryl ester (ChE (22:5)) and triglycerides (TG(48:1), TG:(50:4), and TG(58:4)).” This research highlights the importance of the tumor microenvironment, particularly oxygen levels, in shaping how cancer cells respond to therapy. By altering their metabolism and storing lipids, prostate tumors may evade treatments designed to trigger ferroptosis. These findings underscore the need to develop new strategies targeting LD dynamics or lipid metabolism to overcome this resistance. Understanding how prostate cancer (Pca) adapts to survive in hypoxic conditions offers a potential avenue for improving therapies. For example, preventing lipid accumulation in cancer cells or releasing stored fats may restore their sensitivity to ferroptosis and improve the effectiveness of current therapies. This approach could have broader implications for treating other solid tumors that share similar metabolic features. DOI - https://doi.org/10.18632/oncotarget.28750 Correspondence to - Noel A.

BUFFALO, NY — July 10, 2025 — A new #research paper was #published in Aging (Aging-US) Volume 17, Issue 6, on June 7, 2025, titled “Spermidine supplementation and protein restriction protect from organismal and brain aging independently.” In this study, led by YongTian Liang and Stephan J. Sigrist from Freie Universität Berlin, Charité Universitätmediz Berlin, and the Leibniz-German Center for Neurodegenerative Diseases (DZNE), researchers investigated how spermidine, a natural substance in the body, and protein intake levels influence aging in fruit flies. They found that spermidine supplementation and changes in protein intake influenced brain health and aging in distinct ways. These insights could guide the development of new strategies to slow age-related decline in humans. “In this study, we combined low- and high-protein diets (2% versus 12% yeast in food) with spermidine supplementation in aging Drosophila fruit flies.” Aging of the brain and body contributes to cognitive decline and diseases in older populations. Scientists have long explored dietary restriction and fasting as ways to slow these processes. This study reveals that spermidine supplementation supports brain health by enhancing mitochondrial function and memory, while protein restriction independently promotes longevity and protects against movement decline. The researchers discovered that spermidine improved memory and preserved physical activity in aging flies regardless of protein intake. In contrast, reducing protein alone boosted mitochondrial activity and extended lifespan without directly enhancing memory. Importantly, the combined approach of protein restriction and spermidine supplementation provided additive benefits, suggesting potential for synergistic effects. This work highlights that spermidine acts through a pathway involving hypusination, a vital process where cells modify proteins to support energy production and repair, while protein restriction works via nutrient-sensing pathways that promote longevity. These independent mechanisms may explain why combining the two interventions offers greater protection against aging effects. Although conducted in flies, the study underscores the possibility of designing dietary and supplement-based interventions to combat human age-related decline. As spermidine levels naturally decline with age, supplementation combined with moderated protein intake could offer a safe way to promote brain health and longevity in humans. The authors point out that it takes further studies in mammals and humans to validate these results. If confirmed, such strategies could lead the way for accessible approaches to promote healthy aging and reduce the burden of cognitive disorders in older populations.

BUFFALO, NY — July 8, 2025 — A new #research paper was #published in Aging (Aging-US) Volume 17, Issue 6, on May 30, 2025, titled “Impact of waist-to-hip and waist-to-height ratios on physical performance: insights from the Longevity Check-up 8+ project.” In this study, researchers led by first author Anna Maria Martone and corresponding author Elena Levati from the Fondazione Policlinico Universitario “Agostino Gemelli” IRCCS and Università Cattolica del Sacro Cuore found that adults with higher waist-to-hip and waist-to-height ratios tend to have poorer physical performance. These simple body shape measures emerged as important tools for assessing strength and mobility, which are essential for maintaining independence as people age. The analysis included data from more than 10,000 Italian adults aged 18 to 98 years who participated in the Longevity Check-up 8+ project, a nationwide health initiative aimed at promoting healthy lifestyles and raising awareness of cardiovascular risks. Researchers measured participants' waist-to-hip (WHR) and waist-to-height (WHtR) ratios and assessed their physical function using the five-repetition chair stand test, a standard evaluation of lower body strength and mobility. “Among 10690 participants (mean age 57.0 ± 14.8 y; 54% females), men exhibited higher WHR and WHtR and a higher prevalence of abnormal values (61% and 71%).” The results showed that individuals with higher waist-to-hip and waist-to-height ratios took longer to complete the test, reflecting reduced physical function. Even after adjusting for lifestyle factors such as diet, exercise habits, and cardiovascular health, these ratios remained strongly linked to poorer performance. The waist-to-height ratio, in particular, proved to be a more effective predictor of physical ability across different age and gender groups. These findings highlight how abdominal fat, already tied to serious health risks like heart disease and diabetes, may also impair mobility and independence as people age. Monitoring waist measurements could help identify individuals at risk of functional decline, offering a simple tool to support public health in aging populations. The waist-to-height ratio is especially valuable because of its simplicity and practicality. Requiring only waist and height measurements, it can be easily used in clinical settings and community health programs to screen for potential mobility issues. Encouraging healthy waist sizes through balanced diets and regular exercise could help preserve physical performance and delay age-related decline. These findings may guide future prevention strategies. By identifying individuals at higher risk, healthcare professionals can implement targeted interventions to support long-term health and independence.

BUFFALO, NY - July 7, 2025 – A new #research paper was #published in Volume 16 of Oncotarget on June 17, 2025, titled “Genetic characteristics of blastic plasmacytoid dendritic cell neoplasm: A single institution experience.” In this study, a research team led by first author Fei Fei and corresponding author Michelle Afkhami from the City of Hope Comprehensive Cancer Center investigated a rare and aggressive type of blood cancer called blastic plasmacytoid dendritic cell neoplasm (BPDCN). Their research uncovered frequent mutations in key genes and identified CCDC50 as a potential biomarker for diagnosis and disease monitoring. These findings could help improve how this cancer is detected and treated in the future. BPDCN most often affects older adults and is known for its rapid progression and poor survival rates. The researchers performed genetic sequencing on 21 patients to better understand the disease. They found that two genes, TET2 and ASXL1, were frequently mutated in these patients and were linked to worse survival, especially in those over 65 years old. “Our study revealed that TET2 (57%) and ASXL1 (33%) were the most frequently mutated genes, followed by NRAS (29%), SRSF2 (14%), ZRSR2 (14%), and KMT2D (14%).” The study also discovered that a gene called CCDC50 was expressed at much higher levels in BPDCN samples compared to other blood cancers, such as acute myeloid leukemia and chronic monomyelocytic leukemia. This suggests that CCDC50 may help clinicians distinguish BPDCN from other similar diseases. Importantly, CCDC50 levels dropped significantly in patients whose disease went into remission, highlighting its potential as a tool for tracking disease activity over time. Researchers further observed that patients who received stem cell transplants lived longer than those who did not, reinforcing the importance of this treatment approach. However, BPDCN remains a challenging disease with an overall poor outlook, making these findings an important step toward better care. This research provides new insights into the genetic changes behind BPDCN and points to CCDC50 as a promising marker to improve diagnosis and monitor treatment success. Larger studies will be needed to confirm these results and bring these discoveries closer to use in routine medical practice.

A new study published recently as the cover of Aging Volume 17, Issue 6, describes a new method to estimate how fast the brain is aging. By analyzing lipids, or fat molecules, in brain tissue, researchers from the National University of Singapore and Hanze University of Applied Sciences created a biological “clock” called DoliClock. This innovation highlights how conditions such as autism, schizophrenia, and Down syndrome are associated with accelerated brain aging. Understanding Brain Aging As people grow older, their brains naturally change. However, in many neurological disorders, these changes seem to appear earlier and progress more rapidly. Disorders like autism, schizophrenia, and Down syndrome reduce quality of life and contribute to premature death. Scientists have long searched for better ways to measure biological age in the brain to understand these processes and develop strategies to slow them down. Most existing methods for estimating biological age rely on genetic markers, such as DNA methylation, which are chemical modifications of DNA. While useful, these approaches may not fully capture the complexity of aging, especially in the brain.

Dr. Andres Cardenas, from the Department of Epidemiology and Population Health at Stanford University, joins host Dr. Evgeniy Galimov to discuss a research paper he co-authored in Volume 17, Issue 2 of Aging (Aging-US), titled “Exposome-wide association study of environmental chemical exposures and epigenetic aging in the National Health and Nutrition Examination Survey.” DOI - https://doi.org/10.18632/aging.206201 Corresponding author - Andres Cardenas - andresca@stanford.edu Video interview - https://www.youtube.com/watch?v=A1I6qoVwkfM Longevity & Aging Series - https://www.aging-us.com/longevity Abstract Epigenetic clocks can serve as pivotal biomarkers linking environmental exposures with biological aging. However, research on the influence of environmental exposures on epigenetic aging has largely been limited to a small number of chemicals and specific populations. We harnessed data from the National Health and Nutrition Examination Survey 1999-2000 and 2001-2002 cycles to examine exposome-wide associations between environmental exposures and epigenetic aging. A total of 8 epigenetic aging biomarkers were obtained from whole blood in 2,346 participants ranging from 50-84 years of age. A total of 64 environmental exposures including phthalates, metals, pesticides, dioxins, and polychlorinated biphenyls (PCBs) were measured in blood and urine. Associations between log2-transformed/standardized exposure measures and epigenetic age acceleration (EAA) were assessed using survey-weighted generalized linear regression. A 1 standard deviation (SD) increase in log2 serum cadmium levels was associated with higher GrimAge acceleration (beta = 1.23 years, p = 3.63e-06), higher GrimAge2 acceleration (beta = 1.27 years, p = 1.62e-05), and higher DunedinPoAm (beta = 0.02, p = 2.34e-05). A 1 SD increase in log2 serum cotinine levels was associated with higher GrimAge2 acceleration (beta = 1.40 years, p = 6.53e-04) and higher DunedinPoAm (beta = 0.03, p = 6.31e-04). Associations between cadmium and EAA across several clocks persisted in sensitivity models adjusted for serum cotinine levels, and other associations involving lead, dioxins, and PCBs were identified. Several environmental exposures are associated with epigenetic aging in a nationally representative US adult population, with particularly strong associations related to cadmium and cotinine across several epigenetic clocks.

Liver cancer, especially hepatocellular carcinoma (HCC), remains a major health concern worldwide. In Latin America, the situation becomes more difficult due to limited access to advanced treatments and the high prevalence of underlying liver diseases. A recent research paper, published in Volume 16 of Oncotarget by researchers from Argentina, Brazil, Chile, and Colombia, offers valuable insights into how patients in the region respond to a widely used immunotherapy regimen. This real-world study explores both the effectiveness of treatment and the risks of immune-related side effects. Understanding Hepatocellular Carcinoma: Why It is So Difficult to Treat Hepatocellular carcinoma is often diagnosed at an advanced stage and frequently occurs in people with pre-existing liver conditions such as cirrhosis. Standard treatments like surgery or local therapies are not always possible in these cases. In recent years, the combination of two drugs—atezolizumab and bevacizumab—has shown promise in extending survival. However, most of the evidence comes from controlled clinical trials that may not represent the realities faced by healthcare providers and patients in Latin America. The Study: Immunotherapy for Hepatocellular Carcinoma in Latin America In a multicenter study titled “Immune-mediated adverse events following atezolizumab and bevacizumab in a multinational Latin American cohort of unresectable hepatocellular carcinoma,” led by Leonardo Gomes da Fonseca from Hospital das Clínicas, Universidade de São Paulo, Brazil, and Federico Piñero from Hospital Universitario Austral, Argentina, researchers aimed to fill that gap. The study included 99 patients with advanced HCC from Argentina, Brazil, Chile, and Colombia. All patients received the combination of atezolizumab and bevacizumab. The main objectives were to assess how frequently immune-related side effects, known as immune-related adverse events (irAEs), occurred and whether these events affected overall survival.

Why Big Animals Do Not Get More Cancer: Revisiting Peto's Paradox

BUFFALO, NY — July 2, 2025 — A new #research perspective was #published in Aging (Aging-US) Volume 17, Issue 6, on May 29, 2025, titled “Peto's paradox's relevance is off the scale.” In this perspective, Dr. Mirre J.P. Simons from the University of Sheffield argues that Peto's paradox—a well-known concept in cancer biology—remains a vital framework for understanding cancer resistance in large animals. Dr. Simons challenges recent claims that dismiss the paradox and emphasizes that the unexpectedly low cancer rates in large species still require explanation. This insight is especially relevant for aging and cancer research. Peto's paradox highlights a puzzling observation: larger animals like elephants and whales, despite having far more cells than smaller animals, do not have proportionally higher cancer rates. If each cell had an equal chance of turning cancerous, bigger animals should develop cancer much more frequently. But in reality, they do not. This suggests that evolution has equipped these animals with powerful biological defenses against cancer. “The field of comparative biology into ageing and cancer was given a strong impetus when Peto identified that humans have substantially more cells than mice, but do not have substantially larger incidence of cancer.” Dr. Simons explains that recent studies showing small increases in cancer with body size do not disprove the paradox. The expected increase, based on basic mathematical models, would be massive—many times greater than what is observed. Instead of rejecting Peto's paradox, the field should focus on understanding how large animals suppress cancer so effectively. The author points out that the key to resolving this paradox may lie in traits that evolved alongside body size, such as tissue environments or specialized cell-control mechanisms. These features might reduce the probability of cancer developing, even in animals with millions or billions more cells than humans. Importantly, this perspective underscores the clinical potential of studying species that resist cancer naturally. Studying these natural defenses may help researchers uncover new ways to understand, prevent, or manage cancer. Because cancer risk increases with age in most species, understanding how some animals limit both aging and cancer may also help explain how these two processes are connected. Dr. Simons cautions against oversimplifying cancer biology by focusing only on genetic mutations. Instead, understanding how cells interact with their environment, known as the tissue microenvironment, may offer deeper insight into how cancer develops or is prevented. By reaffirming the importance of Peto's paradox, this research perspective encourages the scientific community to explore the evolutionary tools nature uses to fight cancer. These insights could improve our understanding of cancer and inspire new strategies to support healthier aging. DOI - https://doi.org/10.18632/aging.206258 Corresponding author - Mirre J.P.

BUFFALO, NY – July 1, 2025 – A new #review was #published in Volume 16 of Oncotarget on June 17, 2025, titled “Optimizing enfortumab vedotin plus pembrolizumab therapy.” First authors Elias Antoine Karam of the Gustave Roussy and Saint-Joseph University of Beirut and Yaghi César Céline from the Saint-Joseph University of Beirut, along with their colleagues, reviewed recent developments about treating advanced urothelial carcinoma (aUC), an aggressive form of bladder cancer. Their review highlights how combining enfortumab vedotin and pembrolizumab as a first-line treatment offers a major improvement for patients with limited options and poor prognoses. Advanced urothelial cancer has traditionally been treated with platinum-based chemotherapy, which often causes serious side effects and offers limited long-term benefit. Many patients are even ineligible for it due to underlying health conditions. The new combination presents a more effective and better-tolerated alternative, as shown in recent clinical trials reviewed by the authors. Enfortumab vedotin targets Nectin-4, a protein present in most urothelial cancer cells, delivering a cancer-killing agent directly into tumors. Pembrolizumab helps the immune system detect and destroy cancer cells. Together, they have shown strong results in extending survival with fewer serious side effects than chemotherapy. These findings led to FDA approval in 2023 for use in a broad range of patients, including those unable to tolerate traditional treatments. “In the phase II KEYNOTE-052 study, pembrolizumab demonstrated significant efficacy as initial therapy in patients with aUC who were ineligible for a cisplatin-based regimen.” The review also compares this new approach with other evolving strategies, such as therapies using nivolumab and chemotherapy combinations. Among current first-line options, enfortumab vedotin and pembrolizumab have produced the most promising outcomes. However, the best course of action following disease progression remains unclear. Other important challenges raised in the review include the high cost of the new therapies, limited patient access to them, and the absence of reliable biomarkers to predict individual response. The authors call for further studies to refine treatment strategies and explore blood-based tools that could guide therapy decisions and minimize side effects. This review offers a clear summary of how recent clinical advances are reshaping the treatment of aUC. It reflects a shift away from traditional chemotherapy toward immunotherapy and targeted, personalized treatments that aim to extend survival and improve quality of life.

A New Vision for Healthcare: Addressing Aging Before Disease Begins

Recent discoveries in #aging research reveal a powerful insight: the biological changes that lead to chronic #diseases begin far earlier than most people realize—often in midlife, well before symptoms appear. This early phase offers a valuable opportunity for prevention. As highlighted in a recent editorial by Marco Demaria, Editor-in-Chief of Aging and a researcher at the European Research Institute for the Biology of Ageing (ERIBA), University Medical Center Groningen, and the University of Groningen (RUG), the aging process itself – not just the diseases it produces – can and should be a primary focus of healthcare. The Problem with Traditional Medicine While modern healthcare has extended lifespan and improved treatment for many diseases, it tends to be insufficient in addressing the complex needs of aging populations. Older individuals frequently experience multiple chronic conditions simultaneously, such as cardiovascular disease, diabetes, cancer, and neurodegenerative disorders. This state of multimorbidity complicates care, increases the use of multiple medications, and reduces quality of life. The dominant traditional healthcare system, which typically begins only after symptoms appear, is costly and insufficient for addressing the interconnected nature of these conditions. A New Model for Healthcare: Insights from the Editorial In his recent editorial, “Rethinking healthcare through aging biology,” published in Aging Volume 17, Issue 5, Dr. Demaria outlines a shift from disease-specific treatment to targeting the biological mechanisms of aging itself, a more integrated and forward-looking approach. He presents three evolving healthcare models.

BUFFALO, NY — June 24, 2025 — A new #research paper was #published in Aging (Aging-US) Volume 17, Issue 5, on May 20, 2025, titled “Short-term moderate caloric restriction in the rhesus macaque attenuates markers of ovarian aging in select populations.” In this study, led by first author Emma S. Gargus and corresponding author Francesca E. Duncan from Feinberg School of Medicine at Northwestern University, researchers explored how dietary changes impact ovarian aging in female rhesus macaques. They found that a three-year moderate reduction in caloric intake preserved a youthful distribution of ovarian follicles and reduced age-related tissue stiffness. These findings are relevant to women's health as they suggest that caloric restriction (CR) may help delay the decline in reproductive function associated with aging. Ovarian aging, which leads to reduced fertility and hormone production, is one of the earliest signs of aging in women. This study investigated whether a 30% reduction in caloric intake could protect the ovaries from age-related damage in nonhuman primates (NHP), whose reproductive biology closely mirrors that of humans. Ovaries were collected from young (10–13 years) and old (19–26 years) rhesus macaques who were either on a diet of moderate caloric restriction or a control diet for three years. “To test the effect of CR on follicle number, follicles were analyzed in histological sections from animals across experimental cohorts: Young Control, Young CR, Old Control, Old CR (n = 4–8/group).” Although total follicle numbers still declined with age, caloric restriction helped maintain the types of follicles most associated with reproductive potential. In older monkeys who were still cycling, even if irregularly, caloric restriction preserved more primordial follicles, the key indicators of ovarian reserve, than in those on a normal diet. The benefits of caloric restriction were also seen in the structure of ovarian tissue. Normally, aging leads to fibrosis, a stiffening of the ovarian environment caused by increased collagen and decreased hyaluronic acid. This study showed that caloric restriction reduced this fibrotic process, suggesting a more supportive environment for maintaining reproductive health. While the diet did not stop the overall loss of follicles with age, it improved the proportion of younger, more viable follicles in aging ovaries. The timing of the dietary intervention also appeared to matter. Positive effects were more noticeable in older animals with irregular cycles than in those who had completely stopped cycling. This indicates that starting caloric restriction at a certain point in the reproductive lifespan may yield the best results. This research is an important step to identifying lifestyle-based strategies that can extend reproductive longevity. Although further studies are needed to test these findings in humans, the work supports the potential of moderate dietary changes to delay ovarian aging and help preserve fertility later in life.

Dr. Josh Mitteldorf summarizes his #research perspective #published in Volume 17, Issue 5 of Aging (Aging-US), titled “Methylation clocks for evaluation of anti-aging interventions.” DOI - https://doi.org/10.18632/aging.206245 Corresponding author - Josh Mitteldorf - aging.advice@gmail.com Author interview - https://www.youtube.com/watch?v=efgNvr5ezTk Video short - https://www.youtube.com/watch?v=YjUvpqMzCGc Abstract Methylation clocks have found their way into the community of aging research as a way to test anti-aging interventions without having to wait for mortality statistics. But methylation is a primary means of epigenetic control, and presumably has evolved under strong selection. Hence, if methylation patterns change consistently at late ages it must mean one of two things. Either (1) the body is evolved to destroy itself (with inflammation, autoimmunity, etc.), and the observed methylation changes are a means to this end; or (2) the body detects accumulated damage, and is ramping up repair mechanisms in a campaign to rescue itself. My thesis herein is that both Type 1 and Type 2 changes are occurring, but that only Type 1 changes are useful in constructing methylation clocks to evaluate anti-aging interventions. This is because a therapy that sets back Type 1 changes to an earlier age state has stopped the body from destroying itself; but a therapy that sets back Type 2 changes has stopped the body from repairing itself. Thus, a major challenge before the community of epigenetic clock developers is to distinguish Type 2 from Type 1. The existence of Type 1 epigenetic changes is in conflict with conventional Darwinian thinking, and this has prompted some researchers to explore the possibility that Type 1 changes might be a form of stochastic epigenetic drift. I argue herein that what seems like directed epigenetic change really is directed epigenetic change. Of five recent articles on “stochastic methylation clocks,” only one (from the Conboy lab) is based on truly stochastic changes. Using the Conboy methodology and a methylation database, I construct a measure of true methylation drift, and show that its correlation with age is too low to be useful.

BUFFALO, NY - June 17, 2025 – A new #research paper was #published in Volume 16 of Oncotarget on June 10, 2025, titled “Exceptional responders to immunotherapy in pancreatic cancer: A multi-institutional case series of a rare occurrence.” The study, led by first author Kavin Sugumar and corresponding author Jordan M. Winter, from University Hospitals Seidman Cancer Center, reports on a rare group of pancreatic cancer (PC) patients who responded remarkably well to immunotherapy, a treatment typically considered ineffective for this cancer type. The analysis, which includes data from 14 patients across multiple U.S. institutions, identifies outcomes that could help refine treatment strategies for one of the most aggressive and deadly forms of cancer. “Between 2020–21, 471 oncologists from 91 major cancer centers in the United States were contacted.” Pancreatic cancer has among the lowest survival rates and few effective therapies. While immunotherapy has transformed the treatment landscape for several other cancers, it generally offers little benefit for pancreatic cancer. However, this study highlights a small but important group of patients who experienced significant and sustained responses to immune-based treatment without chemotherapy. Most had advanced or metastatic disease and had already progressed after standard treatments. Among the 14 patients, 82% had partial tumor shrinkage, and nearly one-third had a notable decrease in tumor markers. The median progression-free survival was 12 months, and most patients were still alive at follow-up, with survival rates of 80% at one year and 70% at two years. These outcomes contrast sharply with standard therapies, which often provide only a few months of benefit for similar patients. Interestingly, while some patients had high microsatellite instability (MSI-high)—a known marker for immunotherapy success—more than half did not, suggesting other biological mechanisms may be involved. This result highlights the need for new biomarkers to be discovered to predict treatment response in future studies. This case series is the largest focused exclusively on exceptional immunotherapy responders in pancreatic cancer. By excluding patients who received chemotherapy, the study isolates the effects of immune-based drugs, including PD-1 inhibitors such as pembrolizumab and nivolumab, CTLA-4 inhibitors like ipilimumab, and agents targeting macrophages. While the sample size is small, the findings challenge the assumption that immunotherapy is ineffective for nearly all pancreatic cancer patients. The study suggests that, under certain biological conditions, this treatment can be remarkably successful. Further research is needed to understand the underlying mechanisms. This work supports the need to reconsider how clinical trials are designed for pancreatic cancer and who is eligible for immunotherapy. Broader criteria and more personalized molecular profiling could help uncover hidden opportunities for treatment in this highly lethal cancer.

BUFFALO, NY - June 13, 2025 – A new #review was #published in Volume 16 of Oncotarget on June 4, 2025, titled “Applying the unattainable triangle in cardio-oncology care: Balancing cost, quality, and time.” In this review, first author John Hoverson, corresponding author Stella Pak, and colleagues from the University of Texas Health Science Center at San Antonio explore how the “unattainable triangle”—a business concept describing the trade-offs between cost, quality, and time—can help improve healthcare delivery in cardio-oncology. As cancer treatments become more complex and often affect the heart, this model highlights the challenge of providing care that is fast, effective, and affordable. Cardio-oncology is an emerging field focused on preventing and managing heart problems caused by cancer therapies. The review explains that high-quality cancer care often requires advanced diagnostics and close collaboration between oncologists and cardiologists, which can drive up costs and time demands. Understanding how to balance these pressures is essential for delivering better outcomes for patients. Many cancer survivors face long-term cardiovascular complications due to their treatment. Early monitoring and intervention can reduce these risks. However, these improvements often come with financial burdens, especially when key tests are not covered by insurance. Meanwhile, both patients and clinicians must manage the burden of tight appointment schedules, long clinic visits, and increasing demands on their time. To improve care quality, the authors emphasize the need for interdisciplinary teamwork and ongoing education. Surveys show that many clinicians are still unfamiliar with cardio-oncology guidelines, which can compromise care. The review also highlights the potential for artificial intelligence and digital tools to streamline care delivery, reduce wait times, and support both patients and providers. Importantly, the authors point out that improving one area—such as quality—can come at the expense of others, like cost or time. They encourage healthcare systems to take a balanced approach, setting clear goals and using integrated care models that consider all three elements of the triangle together. “While a perfect model for managing the unattainable triangle may be simply that, ‘unattainable', investments in research, patient-centered care, data-driven decision-making, and financial alignment with payers will be crucial to the long-term success of both patient outcomes and the organization's profitability.” While achieving perfect balance may be difficult, the review suggests that using the unattainable triangle as a guiding framework can help hospitals and clinicians make smarter, more sustainable decisions. As cardio-oncology continues to expand in response to the growing number of cancer survivors with cardiovascular needs, this approach could help improve patient outcomes and strengthen healthcare systems.

BUFFALO, NY — June 12, 2025 — A new #research paper was #published in Aging (Aging-US) Volume 17, Issue 5, on May 3, 2025, titled “APOE genotype and biological age impact inter-omic associations related to bioenergetics.” In this study, led by first author Dylan Ellis and corresponding author Noa Rappaport from the Institute for Systems Biology, researchers discovered that different versions of the APOE gene—particularly ε2 and ε4—are linked to metabolic patterns associated with aging and Alzheimer's disease risk. Both variants were linked to increased levels of diacylglycerols, a type of fat molecule connected to insulin resistance and inflammation, suggesting shared disruptions in how the body regulates energy. The research team analyzed data from over 2,200 adults without an Alzheimer's diagnosis, exploring how APOE genotypes influence biological age, a measure of health that reflects how quickly or slowly someone is aging at a cellular level. They found that the same metabolic disturbances seen in ε2 carriers were also present in people considered biologically older, revealing unexpected overlap between genetic risk and aging-related metabolic changes. To examine these connections in more detail, the researchers used a multi-omics approach, combining blood-based metabolism and protein data, gut bacteria analysis from stool samples, and clinical chemistry data. This method allowed them to map how genetic differences and biological aging affect the body's energy systems. They observed altered connections between glucose metabolism, inflammatory markers, and key molecules that play roles in energy production, indicating early disruptions that could contribute to age-related diseases. One of the study's surprising findings was that the ε2 variant, usually associated with longer life and reduced Alzheimer's risk, showed metabolic traits similar to those found in insulin-resistant individuals. This suggests that ε2 may carry metabolic disadvantages earlier in life, with its protective effects becoming more pronounced later. Conversely, ε4—linked to greater Alzheimer's risk—may exert its influence based on interactions with lifestyle factors like diet, sex, and overall health status. “‘Omics association patterns of ε2-carriers and increased biological age were also counter-intuitively similar, displaying significantly increased associations between insulin resistance markers and energy-generating pathway metabolites.” By identifying these shared biological signatures, this study offers a new framework for understanding how genes and metabolism work together to influence aging. These findings could support more personalized health strategies aimed at delaying biological aging and reducing the risk of chronic diseases. As aging populations grow worldwide, understanding these pathways is essential to improving healthspan.

As we age, our brains become more sensitive to stress and disease. A recent study sheds light on a lesser-known risk: reduced oxygen levels. The study, titled “Defining the hypoxic thresholds that trigger blood-brain barrier disruption: the effect of age” and recently published as the cover for Volume 17, Issue 5 of Aging (Aging-US), found that low oxygen—also called hypoxia—can harm the aging brain by disrupting the blood-brain barrier (BBB). This damage may contribute to cognitive decline, memory problems, and an increased risk of dementia. Understanding Hypoxia in the Brain The brain relies on a steady supply of oxygen to stay healthy. When oxygen levels fall—a condition known as hypoxia—the brain undergoes changes to adapt. These changes include the remodeling of blood vessels and, importantly, a weakening of the blood-brain barrier. The BBB acts as a filter, protecting brain tissue from harmful substances. When it breaks down, it can lead to inflammation, brain cell damage, and cognitive issues. Hypoxia is common in older adults, especially those with conditions like sleep apnea, chronic obstructive pulmonary disease (COPD), heart failure, and asthma. That is why understanding the connection between low oxygen and the aging brain is crucial for preventing long-term neurological damage.

BUFFALO, NY – June 9, 2025 – A new #research paper was #published in Volume 16 of Oncotarget on May 20, 2025, titled “Cigarette smoke and decreased DNA repair by Xeroderma Pigmentosum Group C use a double hit mechanism for epithelial cell lung carcinogenesis.” In this study, led by first author Nawar Al Nasralla and corresponding author Catherine R. Sears, from the Division of Pulmonary, Critical Care, Sleep and Occupational Medicine, Indianapolis and the Richard L. Roudebush Veterans Affairs Medical Center, researchers investigated how cigarette smoke and reduced DNA repair capacity contribute together to the development of lung cancer. They found that when a critical DNA repair protein called XPC is decreased and lung cells are exposed to cigarette smoke, the combination causes extensive damage and significantly increases cancer risk. Non-small cell lung cancer (NSCLC) develops through both genetic and environmental factors. This study focused on how cigarette smoke affects the body's natural ability to repair DNA. The researchers studied the role of XPC, a protein essential for recognizing and repairing harmful DNA changes caused by tobacco smoke. They found that low levels of XPC — commonly seen in lung cancer patients — made lung cells less capable of repairing DNA. This made the cells unstable and more likely to become cancerous. These changes were most pronounced in normal lung cells, suggesting that the earliest stages of disease occur before cancer is even detected. The findings support a “double hit” model, where both cigarette smoke and reduced DNA repair work together to drive cancer development. In laboratory experiments, normal lung cells with low XPC levels showed more damage and cell death after cigarette smoke exposure. By contrast, lung cancer cells were more resistant to smoke damage, even when XPC was low, indicating that critical changes had likely occurred earlier in the disease process. “Our study suggests that cigarette smoke exposure leads to decreased XPC mRNA expression, exacerbates total and oxidative DNA damage, hinders NER, and may contribute to lung cancer development.” The study also showed that DNA repair ability declined significantly in healthy cells after smoke exposure, but this effect was not seen in cancer cells. In addition, the researchers confirmed that XPC gene activity was lower in actual lung tumor tissue compared to nearby healthy lung tissue. This pattern was consistent across both adenocarcinoma and squamous cell carcinoma, the two main types of NSCLC. These results add to our understanding of how lung cancer begins at the molecular level. By showing how cigarette smoke and reduced DNA repair combine to create genetic instability, the research points toward new strategies for prevention. A better understanding of XPC's role could help identify high-risk individuals and inform future efforts to stop lung cancer before it begins.

Morgan - stefanie@agelessrx.com Author interview - https://www.youtube.com/watch?v=2qlIiVh2OJs Video short - https://www.youtube.com/watch?v=z5j2nyK2HZ8 Abstract Design: This 48-week decentralized, double-blinded, randomized, placebo-controlled trial (NCT04488601) evaluated the long-term safety of intermittent low-dose rapamycin in a healthy, normative-aging human cohort. Participants received placebo, 5 mg or 10 mg compounded rapamycin weekly. The primary outcome measure was visceral adiposity (by DXA scan), secondary outcomes were blood biomarkers, and lean tissue and bone mineral content (by DXA scan). Established surveys were utilized to evaluate health and well-being. Safety was assessed through adverse events and blood biomarker monitoring. Results: Adverse and serious adverse events were similar across all groups. Visceral adiposity did not change significantly (ηp2 = 0.001, p = 0.942), and changes in blood biomarkers remained within normal ranges. Lean tissue mass (ηp2 = 0.202, p = 0.013) and self-reported pain (ηp2 = 0.168, p = 0.015) improved significantly for women using 10 mg rapamycin. Self-reported emotional well-being (ηp2 = 0.108, p = 0.023) and general health (ηp2 = 0.166, p = 0.004) also improved for those using 5 mg rapamycin. No other significant effects were observed. Conclusions: Low-dose, intermittent rapamycin administration over 48 weeks is relatively safe in healthy, normative-aging adults, and was associated with significant improvements in lean tissue mass and pain in women. Future work will evaluate benefits of a broader range of rapamycin doses on healthspan metrics for longevity, and will aim to more comprehensively establish efficacy.

Targeting PCNA-Androgen Receptor Interaction Suppresses Prostate Cancer Cell Growth

BUFFALO, NY - June 4, 2025 – A new #research paper was #published in Volume 16 of Oncotarget on May 20, 2025, titled “Targeting PCNA/AR interaction inhibits AR-mediated signaling in castration resistant prostate cancer cells." In this study, authors Shan Lu and Zhongyun Dong from the University of Cincinnati College of Medicine investigated how interfering with a protein interaction could reduce prostate cancer growth. Their study based on prostate cancer cells shows that blocking the link between PCNA, a protein important for DNA repair, and the androgen receptor (AR), which drives prostate cancer growth, can slow down cancer cell multiplication. This discovery could lead to a new treatment for patients with advanced prostate cancer, particularly those no longer responding to hormone therapy. Prostate cancer is one of the most common cancers in men. Many patients eventually become resistant to hormone treatment. In this advanced stage, called castration-resistant prostate cancer (CRPC), tumors continue to grow by using either the full-length androgen receptor (AR-FL) or altered versions called AR variants (AR-Vs). This study shows that the interaction between AR and PCNA helps both AR-FL and AR-Vs remain active, supporting cancer cell survival and growth. The researchers identified a new region in the AR that binds to PCNA. They developed a small peptide, R9-AR-PIP, to mimic this region and block the AR-PCNA connection. They found that this peptide reduced AR's ability to bind DNA and lowered the levels of key genes involved in cancer cell growth. Importantly, the peptide was effective against both types of AR, including the variant forms that are especially challenging in CRPC. “We identified a second PIP-box (PIP-box592) in the DNA binding domain of AR and found that dihydrotestosterone enhances the binding of full-length AR (AR-FL) but not a constitutively active variant (AR-V7) to PCNA.” They also tested a small molecule, PCNA-I1S, which interferes with PCNA's ability to move to the cell nucleus and interact with AR. This molecule showed similar effects as the peptide, reducing AR activity and stopping cancer cell growth. Together, these findings suggest that targeting PCNA/AR interactions could be a promising strategy to fight CRPC, especially in patients with limited treatment options. One key result was that both the peptide and the small molecule reduced the levels of cyclin A2, a protein that helps cells divide and is often overexpressed in CRPC. Since this protein is linked to patients' poor outcomes, its reduction could be especially beneficial. This study improves our understanding of how prostate cancer continues to grow even after hormone treatments fail. By blocking a crucial helper of the androgen receptor, researchers have uncovered a new way to potentially slow or stop the disease. Further studies in animal models are needed, but this approach could lead to more effective treatments for men with advanced prostate cancer.

This triple therapy, known as IRT, was recently detailed in a study published in Oncotarget. Understanding Glioblastoma and the Need for Better Therapies Glioblastoma is the most common and aggressive malignant brain tumor in adults. It grows quickly and is difficult to treat, often leading to poor outcomes. Most patients survive less than 15 months after diagnosis, even when treated with surgery, radiation, and the chemotherapy drug temozolomide (TMZ).

Blocking PRDX1 Protein May Improve Chemotherapy Response in Ovarian Cancer

BUFFALO, NY - June 3, 2025 – A new #research paper was #published in Volume 16 of Oncotarget on May 19, 2025, titled “PRDX1 protects ATM from arsenite-induced proteotoxicity and maintains its stability during DNA damage signaling." In this study, led by first author Reem Ali and corresponding author Dindial Ramotar from Hamad Bin Khalifa University in Qatar, researchers discovered that a protein called PRDX1 helps maintain the stability of ATM, a key protein involved in repairing damaged DNA, especially when cells are under stress from arsenite exposure. The study found that without PRDX1, cells lose their ability to repair DNA and become more sensitive to chemotherapy. This finding suggests that targeting PRDX1 could improve the success of some cancer treatments. PRDX1 is already known for its role in protecting cells from oxidative damage, but this study shows it also plays a role in the DNA repair process. ATM is an essential protein that detects breaks in DNA and starts the repair process. When PRDX1 is missing, ATM is rapidly lost, especially when cells are exposed to arsenite, a toxic substance found in the environment. Without ATM, the DNA repair system fails, leaving cells more vulnerable to damage. By using both human cell lines and clinical samples from ovarian cancer patients, the team showed that high levels of PRDX1, along with ATM and MRE11 (another DNA repair protein), were linked to tumors' aggressive features and lower patient survival rates. This pattern suggests that tumors with high PRDX1 may resist chemotherapy by increasing their DNA repair capacity. On the other hand, removing PRDX1 weakened the repair system and made cancer cells more responsive to DNA-damaging platinum drugs. The study also showed that combining low doses of arsenite with drugs that either block ATM or damage DNA caused a much higher rate of cancer cell death in cells that lacked PRDX1. These results suggest a new treatment approach: lowering PRDX1 levels to make cancer cells more sensitive to DNA-damaging platinum therapies already in use. This highlights PRDX1 not only as a protector of cell function but also as a potential weak point in cancer cells. “As such, we propose that small molecule inhibitors of PRDX1, or single nucleotide polymorphisms that compromise PRDX1 function, in combination with low doses of arsenite can be exploited to treat chemo-resistant tumours.” These findings open the door for the use of PRDX1 as a biomarker to predict treatment response and as a promising target for new combination therapies. For patients with ovarian cancer and potentially other tumors, adjusting PRDX1 levels may help overcome drug resistance and improve outcomes.

BUFFALO, NY - May 21, 2025 – A new #review was #published in Volume 16 of Oncotarget on May 19, 2025, titled “Advancements in bladder cancer treatment: The synergy of radiation and immunotherapy." Researchers from the University of California, Irvine, led by Nazmul Hasan, reviewed recent clinical and scientific advances in combining radiation therapy with immunotherapy for bladder cancer. The article summarizes growing evidence that this combined approach may strengthen the immune response and improve long-term disease control. This strategy is especially important for patients who are not candidates for surgery or who respond poorly to conventional treatments. Bladder cancer is a serious and frequent condition, particularly affecting older men. Traditional treatments—surgery, chemotherapy, and radiation—can be effective, but they often fail to prevent cancer reappearance in advanced cases. The review explores how combining radiation and immunotherapy could improve outcomes by helping the immune system detect and destroy cancer cells more effectively. Radiation therapy destroys cancer cells and triggers the release of tumor signals that attract immune cells. Immunotherapy, including drugs like pembrolizumab and nivolumab, helps the immune system work better by blocking proteins that allow cancer to evade detection. Used together, these treatments may produce a stronger, more widespread anti-tumor effect, even at distant sites not directly targeted by radiation. The review discusses several clinical trials that support this approach. One phase II study reported that combining radiation with the immunotherapy drug durvalumab led to promising survival rates and manageable side effects. Another trial in Australia tested pembrolizumab with radiation and chemotherapy, resulting in high tumor control and extended patient survival. However, the review also points out that other trials showed serious side effects when high doses or multiple immunotherapy drugs were used at once. "Joshi et al. performed a phase II study to determine the safety and efficacy of combining radiation therapy with durvalumab, a PD-L1 inhibitor, in patients who were ineligible for surgery or cisplatin-based chemotherapy." While the combination approach is promising, the authors emphasize that more research is needed to refine this treatment strategy. One major challenge is determining which patients are most likely to benefit. Future studies should focus on identifying reliable biomarkers, such as tumor mutation burden or immune activity, to guide personalized treatment plans. This review highlights the potential of combining radiation and immunotherapy to improve outcomes for bladder cancer patients. With continued research and careful treatment design, this approach could offer new treatment options for those facing aggressive or hard-to-treat forms of the disease.

Scientists have engineered small, targeted proteins that can penetrate brain cancer cells and prevent them from invading healthy tissue, offering a promising new approach to treating glioblastoma multiforme (GBM), one of the deadliest forms of brain cancer. This strategy was developed by researchers at the University of Nevada, Reno, and published recently in Oncotarget. The Challenge of Treating Glioblastoma Multiforme Glioblastoma is an aggressive and fast-growing brain tumor that infiltrates healthy brain tissue, making complete surgical removal nearly impossible. Standard treatments like chemotherapy and radiation can slow its growth but rarely prevent it from returning. One major reason for this invasiveness is a group of enzymes known as matrix metalloproteinases (MMPs), which break down surrounding tissue to allow cancer cells to spread. Among these, MMP-9 plays a particularly important role in driving tumor progression and resisting existing therapies. Attempts to block MMPs using small-molecule drugs have failed in clinical trials due to problems like poor selectivity and harmful side effects. Researchers have been searching for safer, more targeted methods to interfere with these enzymes and limit glioblastoma's spread. The Study: Engineered Proteins to Inhibit Tumor Invasion In the study called “Effect of TIMPs and their minimally engineered variants in blocking invasion and migration of brain cancer cells,” researchers Elham Taheri and Maryam Raeeszadeh-Sarmazdeh investigated tissue inhibitors of metalloproteinases (TIMPs), which are natural blockers of MMPs, and their engineered modified versions made to work better. Specifically, the team studied TIMP-1, TIMP-3, along with two engineered molecules, mTC1 and mTC3, in laboratory cell models of GBM.

BUFFALO, NY - May 14, 2025 – A new #review paper was #published in Volume 16 of Oncotarget on May 9, 2025, titled “Relationship between ABO blood group antigens and Rh factor with breast cancer: A systematic review and meta-analysis." A comprehensive study, led by first authors Rahaf Alchazal from Yarmouk University and Khaled J. Zaitoun from Johns Hopkins University School of Medicine and Jordan University of Science and Technology, examined the potential link between blood type and breast cancer. The research team conducted a systematic review and meta-analysis of 29 previously published studies, involving more than 13,000 breast cancer patients and over 717,000 controls. “Researchers searched for studies on breast cancer patients and ABO blood groups across four major databases: PubMed, Scopus, Web of Science, and Google.“ Breast cancer is the most common cancer among women worldwide. Identifying risk factors is vital for early detection and prevention. While many studies have explored lifestyle and genetic causes, this analysis focused on the ABO blood group system. By pooling global data, the researchers found that blood type A was the most common among breast cancer patients and was significantly associated with an 18% increased risk compared to type O. The study did not find a significant association between breast cancer and blood types B, AB, or Rh factor. Although the results do not prove causation, they point to a biological pattern worth further investigation. Blood group antigens are proteins found on the surface of cells, including breast tissue. These molecules may influence how cancer develops and spreads by interacting with the immune system or affecting cell behavior. This meta-analysis is the most extensive review to date on this topic, based on studies conducted across Asia, Europe, Africa, and the Americas. While previous research found unclear conclusions, this large-scale evaluation provides stronger evidence for a possible connection between blood type A and breast cancer risk. Researchers note that regional differences, genetic diversity, and study quality may affect individual results. Nevertheless, the overall trend supports considering blood type A as a potential risk marker. This insight could help shape screening guidelines, encouraging earlier or more frequent checkups for women with this blood type. Further research is needed to understand why blood type A may play a role in cancer development. Future studies may explore genetic mechanisms, immune responses, and other biological pathways. These efforts could lead the way for more personalized cancer prevention and care strategies. DOI - https://doi.org/10.18632/oncotarget.28718 Correspondence to - Khaled J.

BUFFALO, NY — May 14, 2025 — A new #research paper was #published in Aging (Aging-US) Volume 17, Issue 4, on April 10, 2025, titled “Impact of Factor Xa inhibitors on cardiovascular events in older patients with nonvalvular atrial fibrillation.” In this study, first author Masahiko Takahashi and corresponding author Keisuke Okawa led a research team from Kagawa Prefectural Central Hospital and Hyogo Medical University that investigated whether Factor Xa inhibitors (Xa-Is)—a type of blood thinner—can reduce the risk of heart-related complications in patients over 80 with nonvalvular atrial fibrillation (NVAF). The study found that patients using Xa-Is experienced significantly fewer cardiovascular problems than those on other anticoagulants. This finding is especially relevant, as older adults face a high risk of both stroke and heart disease. Atrial fibrillation is a common heart rhythm disorder, particularly in the elderly, that increases the risk of blood clots, heart failure, and stroke. Anticoagulants are often prescribed to prevent clots, but not all types have the same effects on heart health. This study focused on comparing Xa-Is—specifically rivaroxaban, apixaban, and edoxaban—with commonly used drugs such as warfarin and dabigatran. Researchers followed more than 1,000 patients aged 80 and above for up to five years to assess the long-term impact of these medications on cardiovascular outcomes. Patients who used Xa-Is had significantly lower rates of heart failure, artery disease, and cardiovascular death. The risk of cardiovascular problems in the Xa-I group was less than half that of those on non-Xa-I medications. These benefits remained even after adjusting for factors like age, existing heart conditions, and kidney function. Additionally, stroke and all-cause death rates were notably lower in the Xa-I group. “Xa-Is may be useful for not only anticoagulation but also the prevention of cardiovascular events in very old patients with NVAF.” What makes Xa-Is different, according to the researchers, is their ability to inhibit a specific biological pathway—known as Factor Xa–PAR2—that contributes to inflammation, fibrosis, and damage in blood vessels and heart tissue. This effect extends beyond their traditional role in preventing blood clots. Although the study was conducted at a single medical center in Japan, its rigorous design and long follow-up period enhance the reliability of the findings for real-world clinical decision-making. While further studies, especially across multiple centers, are needed to confirm the full range of benefits, this study strongly suggests that Xa-Is may offer broader cardiovascular protection for very old patients. The findings could influence how clinicians choose blood thinners for elderly individuals with atrial fibrillation, potentially improving both survival and quality of life in this growing population.

Werner syndrome is a rare condition marked by accelerated aging. A recent study, featured as the cover paper in Aging (Aging-US), Volume 17, Issue 4, led by researchers at the University of Oslo and international collaborators, suggests that nicotinamide adenine dinucleotide (NAD+), a vital molecule involved in cellular energy production, may be key to understanding this disease and developing future strategies to manage it. Understanding Werner Syndrome Werner syndrome (WS) is a rare genetic condition that causes people to age more quickly than normal. By their 20s or 30s, individuals with WS often show signs typically associated with older age, such as cataracts, hair loss, thinning skin, and heart disease. This premature aging is caused by mutations in the WRN gene, which normally helps repair DNA and protect cells from damage. While the WRN gene's role in maintaining genetic stability is well understood, the reasons behind the rapid decline of cells in WS patients are still not fully clear. The Study: Investigating NAD+ in Werner Syndrome Nicotinamide adenine dinucleotide levels naturally decline with age. In the study titled “Decreased mitochondrial NAD+ in WRN deficient cells links to dysfunctional proliferation,” researchers investigated whether this decline is more severe in people with WS and whether restoring NAD+ levels could help slow the aging process in these patients.

BUFFALO, NY - May 9, 2025 – A new #research paper was #published in Oncotarget, Volume 16, on May 8, 2025, titled “METTL3 promotes oral squamous cell carcinoma by regulating miR-146a-5p/SMAD4 axis." In this study, researchers Jayasree Peroth Jayaprakash, Pragati Karemore, and Piyush Khandelia from the Birla Institute of Technology and Science, India, discovered that a molecule called METTL3 contributes to the development and spread of oral squamous cell carcinoma (OSCC). The study shows that METTL3 increases the levels of a small RNA molecule called miR-146a-5p, which blocks SMAD4, a key tumor-suppressing gene. These findings help explain why oral cancers are difficult to treat and may offer a new target for more effective therapies. Oral squamous cell carcinoma is a common and aggressive cancer affecting the mouth and throat. It has a high death rate, mainly due to late detection, treatment resistance, and the cancer's ability to invade nearby tissues. In this study, the researchers focused on METTL3, an enzyme that adds chemical tags known as m6A marks to RNA, which change how genetic information is used by cells. They found that METTL3 is unusually active in OSCC cells, causing an increase in miR-146a-5p. This molecule, in turn, blocks the function of SMAD4, which helps control how cells grow and die in our bodies. “METTL3, the primary m6A RNA methyltransferase, is significantly upregulated in OSCC cells leading to increased global m6A levels.” When METTL3 was reduced or chemically blocked, miR-146a-5p levels dropped and SMAD4 levels increased. This shift slowed the growth of cancer cells, increased their death, and made them less likely to spread. When researchers reintroduced miR-146a-5p or lowered SMAD4 levels again, the cancer-promoting behavior returned. These results show that the METTL3–miR-146a-5p–SMAD4 pathway plays a key role in OSCC. The findings open up new possibilities for treatment. Drugs that block METTL3 or miR-146a-5p or that restore SMAD4 could slow or stop tumor growth. One such drug, STM2457, which targets METTL3, has already shown promise in lab studies. As research progresses, targeting this molecular pathway may offer a new strategy in treating OSCC. This discovery improves our understanding of how OSCC develops and avoids the body's defenses. By interfering with this newly discovered pathway, future treatments may become more successful, improving survival rates and quality of life for people with this disease.

A recent #study from Assiut University Hospital in Egypt, published in #Oncotarget, presents a promising strategy for patients with metastatic #colorectalcancer (mCRC). The #research introduces a gentler yet effective maintenance therapy that may extend survival, enhance quality of life, and offer a more accessible treatment option for mCRC patients worldwide. The Challenge of Treating Metastatic Colorectal Cancer Colorectal cancer is one of the most common causes of cancer-related deaths worldwide. When it spreads to other parts of the body—a stage known as mCRC—it becomes much more difficult to treat. At this stage, clinicians often use strong drug combinations like FOLFOX or CAPOX, which mix chemotherapy drugs to stop cancer growth. FOLFOX combines three drugs given intravenously, while CAPOX includes two of the same drugs, with one taken as a pill. While effective, these treatments can cause serious side effects. For example, one of the main drugs, oxaliplatin, can lead to nerve damage, making it painful or difficult to use the hands and feet. Fatigue, diarrhea, and other issues are also common. Over time, these side effects may force clinicians to stop or adjust the treatment, even if it is working. That is where maintenance therapy comes in. After the cancer is controlled, clinicians often switch to a gentler treatment plan to keep it from returning. The challenge is finding a therapy that continues to work without causing too many side effects, especially in places where access to expensive or intensive treatments is limited.

New Insights into p53: A Powerful Gene's Role in Cancer Therapy

A new study from the Sidney Kimmel Comprehensive Cancer Center and Johns Hopkins University School of Medicine, published in Oncotarget, reveals that the gene p53, long known as the “guardian of the genome,” may be even more powerful than previously thought. By studying it in non-cancerous human cells, researchers discovered how p53 stops risky cell growth and uncovered two new potential targets for cancer therapy. Understanding p53: The Genome's Guardian Against Cancer The p53 gene is one of the most important natural defenses our body has against cancer. When functioning properly, p53 detects damage in a cell's DNA and either stops the cell from dividing or pushes it to self-destruct. This process helps prevent potentially dangerous mutations from spreading. However, many cancers find ways to silence or mutate p53, allowing uncontrolled growth and resistance to treatments. Studying p53 in a clear and accurate way has long been a challenge. Most cancer cell models used in research already carry numerous genetic mutations, which can mask or alter how p53 truly functions. To fully understand this vital tumor-suppressing gene, scientists needed a model that closely resembled healthy, genetically stable human cells—yet could still be maintained and studied over time in the laboratory. The Study: Exploring p53 in Normal and Cancer Cell Models Researchers Jessica J. Miciak, Lucy Petrova, Rhythm Sajwan, Aditya Pandya, Mikayla Deckard, Andrew J. Munoz, and Fred Bunz explored p53 activity using a uniquely suitable cell line: hTERT-RPE1. These non-cancerous human cells are immortalized using telomerase, meaning they continue dividing like cancer cells, but without the chaotic mutations seen in tumors. This makes them an excellent model for studying how p53 operates in near-normal conditions.

Despite decades of research, treatment for osteosarcoma has remained largely unchanged, especially for patients whose cancer spreads or returns. However, a growing body of evidence, summarized in the review “SETDB1 amplification in osteosarcomas: Insights from its role in healthy tissues and other cancer types,” published in Oncotarget, highlights the gene regulator SETDB1 as a potential key player in cancer progression, immune system evasion, and resistance to therapy. Targeting this protein may offer a new direction for developing more effective treatments. Understanding Osteosarcoma Osteosarcoma is a rare but aggressive bone cancer that primarily affects teenagers and young adults. While current treatments like surgery and chemotherapy can help some patients, outcomes are much worse for those with relapsed or advanced disease. One of the reasons osteosarcomas are so difficult to treat is their complex and unstable genetics. Unlike cancers with well-defined mutations, osteosarcomas involve chaotic DNA rearrangements, making it difficult to identify precise drug targets. Adding to the challenge, the immune system often fails to recognize these cancer cells, limiting the success of immunotherapy.

AI That Measures Its Own Uncertainty Could Improve Liver Cancer Detection

BUFFALO, NY - April 8, 2025 – A new #editorial was #published in Oncotarget, Volume 16, on April 4, 2025, titled “Deep learning-based uncertainty quantification for quality assurance in hepatobiliary imaging-based techniques." Dr. Yashbir Singh from Mayo Clinic and his colleagues discussed how artificial intelligence (AI) can improve liver imaging by recognizing when it might be wrong. This approach, called “uncertainty quantification,” helps clinicians better detect liver cancer and other diseases by pointing out areas in medical scans that need a second look. The authors explain how these AI tools could make imaging results more accurate and reliable, which is especially important when diagnosing serious conditions like liver tumors. Liver and bile duct imaging is difficult because of the organ's complex structure and differences in image quality. Even skilled radiologists can struggle to identify small or hidden tumors, especially in patients with liver damage or scarring. The editorial explains how new AI models not only read medical images but also measure their own confidence. When the AI system is unsure, it can alert clinicians to take a closer look. This extra layer of information can reduce missed diagnoses and improve early detection of liver cancer. One of the most advanced tools described in the editorial is called AHUNet (Anisotropic Hybrid Network). This AI model works with both 2D and 3D images and can highlight which parts of a scan it is most confident about. It performed well when measuring the entire liver and showed how its confidence dropped when scanning smaller or multiple lesions. This feature helps clinicians know when more testing or review is needed. The authors also looked at other AI models used in liver imaging. Some tools were able to analyze liver fat using ultrasound images and give clinicians both a result and a confidence score. Others improved the speed and accuracy of liver magnetic resonance imaging (MRI) scans, helping to create clear images in less time. These advancements could help hospitals work faster and provide better care. The editorial highlights how this technology can be especially helpful in smaller clinics. If they do not have liver specialists, they could still use AI systems that flag uncertain results and send them to larger centers for review. Such an approach could improve care in rural or less-resourced areas. “Radiology departments should develop standardized reporting templates that incorporate uncertainty metrics alongside traditional imaging findings.” By using AI tools that know when to second-guess themselves, clinicians may soon have more reliable methods for detecting liver cancer and monitoring liver disease. The authors suggest that uncertainty-aware AI may soon become a vital part of everyday medical imaging, supporting faster and more accurate decisions in liver disease care.

BUFFALO, NY - April 4, 2025 – A new #research paper was #published in Oncotarget, Volume 16, on March 27, 2025, titled “Imipridones ONC201/ONC206 + RT/TMZ triple (IRT) therapy reduces intracranial tumor burden, prolongs survival in orthotopic IDH-WT GBM mouse model, and suppresses MGMT." Researchers from Brown University, led by first author Lanlan Zhou and corresponding author Wafik S. El-Deiry, have shown that combining a new class of drugs called imipridones with standard glioblastoma treatments significantly improves outcomes in mice. The study tested ONC201 and its analog ONC206 in combination with radiation therapy and the chemotherapy drug temozolomide (TMZ), a regimen referred to as IRT. This triple therapy slowed tumor growth and extended survival in a mouse model of glioblastoma, offering a potential new strategy for one of the most aggressive and treatment-resistant brain cancers. Glioblastoma is a fast-growing brain tumor with a poor prognosis and limited treatment options. Standard care typically includes surgery, radiation, and TMZ, but most patients still face a short life expectancy. While ONC201 and ONC206 are currently being studied in clinical trials as single agents, there has been limited information on how they interact with standard therapies. This study is the first to show that both drugs work synergistically with radiation and TMZ, strengthening their overall effects. The results showed that in both laboratory-grown tumor cells and mice, the triple therapy significantly slowed cancer cell growth, reduced tumor size, and prolonged survival compared to using any single or double treatment. Mice treated with IRT lived an average of 123 days, with some surviving more than 200 days—far longer than the 44 to 103 days observed with other treatment combinations. In addition to directly killing tumor cells, ONC201 and ONC206 lowered the expression of MGMT, a protein that helps tumors resist chemotherapy, making the treatment more effective. The researchers also found that the triple therapy reshaped the tumor environment. It decreased levels of harmful molecules that promote tumor growth and immune evasion while increasing signals that activate the immune system. This dual action—directly attacking tumors and boosting immune responses—adds to the potential impact of this treatment approach. “Overall, our preclinical findings support further exploration of the ONC201 and ONC206 IRT regimen as a potential treatment for GBM and diffuse gliomas with H3K27M mutations.” While these findings are based on preclinical mouse models, they offer strong support for advancing this triple therapy to clinical trials. ONC201 and ONC206 are promising due to their ability to cross the blood-brain barrier and enhance the effects of standard treatment. This combination could lead to more effective therapies for glioblastoma and other hard-to-treat brain tumors. DOI - https://doi.org/10.18632/oncotarget.28707 Correspondence to - Wafik S.
