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.

Bladder cancer remains a significant clinical concern, with more than 85,000 new diagnoses and nearly 19,000 deaths reported annually in the United States. While current treatments like surgery, chemotherapy, and radiation can be effective for early-stage disease, many patients with advanced or recurrent cancer face limited options. A recent review, published in Oncotarget by researchers from the University of California, Irvine, analyzes the growing body of evidence supporting the combination of radiation therapy and immunotherapy for bladder cancer. Led by Nazmul Hasan, the work synthesizes clinical data and biological mechanisms that suggest this strategy could enhance anti-tumor responses in specific patient groups.

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.

Dr. Stefanie Morgan joins Dr. Robert Dudley from AgelessRx to discuss a #research paper she co-authored that was #published in Volume 17, Issue 4 of Aging, entitled “Influence of rapamycin on safety and healthspan metrics after one year: PEARL trial results.” DOI - https://doi.org/10.18632/aging.206235 Corresponding author - Stefanie L. 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.

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.

Researchers at Brown University have developed a combination treatment that significantly increases survival in mice with glioblastoma (GBM), a highly aggressive and treatment-resistant brain cancer. The approach uses a new class of drugs called imipridones along with radiation therapy and standard chemotherapy. 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). This treatment may slow the disease, but it does not typically stop it.

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.

In a world where we are living longer but not always healthier, scientists are searching for ways to add life to our years, not just years to our lives. A recent study published in Aging (Aging-US), Volume 17, Issue 4, led by researchers at the National University of Natural Medicine, suggests that certain common foods, already known for their health benefits, might also help slow or even reverse epigenetic or biological aging. These foods, rich in specific plant compounds, appear to influence our DNA in ways that may slow down the body's epigenetic clock.

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.

BUFFALO, NY — May 1, 2025 — A new #research paper was #published in Aging (Aging-US) on April 2, 2025, as the #cover of Volume 17, Issue 4, titled “Decreased mitochondrial NAD+ in WRN deficient cells links to dysfunctional proliferation.” In this study, the team led by first author Sofie Lautrup and corresponding author Evandro F. Fang, from the University of Oslo and Akershus University Hospital in Norway, discovered that cells from people with Werner syndrome (WS)—a rare genetic disorder that causes premature aging—have low levels of a molecule called NAD+ in their mitochondria. This molecule is essential for energy production, cellular metabolism, and maintaining cell health. The researchers also found a potential way to improve cell function in WS patients, pointing to new directions for treating age-related decline and other premature aging disorders. Werner syndrome leads to signs of aging much earlier than normal, including problems such as cataracts, hair loss, and atherosclerosis by age 20 to 30. The team found that when the WRN gene is missing or damaged, cells cannot maintain healthy NAD+ levels in their mitochondria. As a result, the cells age more quickly and stop growing properly. When the researchers boosted NAD+ levels using nicotinamide riboside (a vitamin B3 compound) the affected stem cells and skin cells from patients showed less aging and improved mitochondrial activity. “Interestingly, only 24 h treatment with 1 mM nicotinamide riboside (NR), an NAD+ precursor, rescued multiple pathways in the WRN−/− cells, including increased expression of genes driving mitochondrial and metabolism-related pathways, as well as proliferation-related pathways.” The study also found that the WRN gene helps regulate other important genes that control how NAD+ is made in the body. Without WRN, this system becomes unbalanced, which affects how cells function, grow, and respond to stress. Although adding more NAD+ helped some cells look healthier, it could not completely fix the growth problems in other types of lab-grown cells. This suggests that while NAD+ supplementation is beneficial, it cannot fully replace the essential functions of the WRN gene. These findings offer new insights into the biological mechanisms of aging and reinforce the therapeutic potential of targeting NAD+ metabolism in age-related and genetic diseases. Future studies will aim to better understand how subcellular NAD+ regulation interacts with mutations like those seen in WS. Finally, this research supports ongoing efforts to develop NAD+-based treatments that could slow cellular aging and improve quality of life for patients with premature aging conditions.

BUFFALO, NY — April 23, 2025 — A new #research paper was #published in Aging (Aging-US) Volume 17, Issue 3, on March 18, 2025, titled “Epigenetic and accelerated age in captive olive baboons (Papio anubis), and relationships with walking speed and fine motor performance.” In this study, led by Sarah J. Neal from The University of Texas MD Anderson Cancer Center, researchers examined how the epigenetic age of baboons—a measure of biological aging based on DNA methylation—compared to their actual age (chronological age) and whether it related to signs of aging like slower walking or reduced hand coordination. While many baboons showed a mismatch between their epigenetic and chronological ages, these differences did not consistently align with physical performance measures. Researchers analyzed blood samples from 140 captive olive baboons (Papio anubis) to determine whether these primates, like humans, show signs of “age acceleration”—a condition where epigenetic age surpasses chronological age. The results revealed that about a quarter of the baboons exhibited accelerated aging, while another quarter showed signs of slower aging, known as “age deceleration.” “We found that epigenetic age was strongly correlated with chronological age, and that approximately 27% of the sample showed age acceleration and 28% showed age deceleration." The scientists then investigated whether these differences were reflected in physical indicators such as walking speed or fine motor skills. To do this, researchers measured walking speed by tracking how quickly baboons moved between points in their enclosures and assessed fine motor skills using a simple task that involved picking up small objects. Older baboons did tend to walk more slowly and perform worse on tasks requiring dexterity, patterns also seen in aging humans. However, these changes were more closely related to chronological age than epigenetic age. Two different methods were used to measure the gap between epigenetic and chronological age. Each method produced slightly different outcomes, highlighting the complexity of defining age acceleration. In one analysis, the oldest baboons appeared to age more slowly epigenetically, possibly reflecting selective survival, where only the healthiest individuals live into old age. This research is among the first to classify baboons based on their epigenetic aging rate and investigate how this links to real-world signs of aging. Although the findings did not provide clear evidence that epigenetic age acceleration leads to physical decline, they point to the importance of DNA methylation as a biomarker in aging research. Because baboons share many biological similarities with humans, these findings help refine how researchers measure aging and assess potential early warning signs of decline. Continued studies in baboons and other primates may improve our understanding of how epigenetic aging influences health and longevity—and could help develop better tools for predicting age-related decline in humans.

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.

BUFFALO, NY — April 16, 2025 — A new #research paper was #published in Aging (Aging-US) Volume 17, Issue 3, on March 12, 2025, titled “DNA methylation entropy is a biomarker for aging.” Researchers Jonathan Chan, Liudmilla Rubbi, and Matteo Pellegrini from the University of California, Los Angeles, led a study that discovered a new way to measure changes in DNA that can help predict a person's age. This method focuses on how random certain chemical tags on DNA become over time. The team compared this new measurement, called methylation entropy, to existing methods and found it performed just as well—or even better. These findings support the idea that changes in our epigenetic information are closely linked to aging and could offer new tools for studying age-related diseases. The study focused on DNA methylation, a process where chemical marks are added to DNA and help control which genes are turned on or off. Scientists have traditionally measured average methylation levels to estimate biological age using “epigenetic clocks.” This study, however, takes a different approach. The researchers used buccal swabs (cells from inside the cheek) from 100 individuals between ages 7 and 84 and applied targeted bisulfite sequencing techniques to measure methylation entropy across 3,000 regions of the genome. Entropy in this context reflects how disordered or varied the methylation patterns are at certain sites on the DNA. The researchers discovered that as people age, the entropy of methylation at many locations changes in a reproducible way. Sometimes it increases, reflecting more random patterns, and sometimes it decreases, showing more uniformity. These shifts are not always tied to how much methylation is happening, which suggests entropy provides new information beyond what traditional methods can offer. To test how well this new metric could predict age, the team used both statistical and machine learning models. They found that methylation entropy predicted age as accurately as traditional methods, and the best results came from combining entropy with other measurements like average methylation and a method called CHALM. These combined models were able to estimate age with an average error of just five years. "[...] methylation entropy is measuring different properties of a locus compared to mean methylation and CHALM, and that loci can become both more or less disordered with age, independently of whether the methylation is increasing or decreasing with age." This research supports the growing theory that aging is partly caused by a gradual loss of epigenetic information—the biological “instructions” that help keep our cells working properly. This insight also connects with recent studies suggesting that restoring this lost information might reverse some signs of aging. While more research is needed to study methylation entropy in other tissues, this work points to a more precise and powerful way to measure biological aging, which could influence the future of aging-related treatments and therapies.

Breast cancer survivors are living longer than ever, thanks to research and medical advances, but new studies suggest that some treatments may come with a hidden cost: accelerated aging. A recent study, titled “Accelerated aging associated with cancer characteristics and treatments among breast cancer survivors,” published in Aging (Aging-US), reveals that breast cancer and its treatments may speed up biological aging, with effects lasting up to a decade post-diagnosis. Breast Cancer and Aging Breast cancer is one of the most common cancers among women worldwide. Medical advancements have dramatically improved survival rates, making it one of the most treatable forms of cancer. Yet, many survivors report lasting symptoms like fatigue, memory issues, and reduced vitality that resemble accelerated aging. This pattern has led scientists to investigate whether treatments for breast cancer might be contributing to biological age acceleration.

Paula Cilleros-Holgado from Pablo de Olavide University discusses a #research paper she co-authored that was #published in Volume 17, Issue 2 of Aging (Aging-US), entitled “Mitochondrial dysfunction, iron accumulation, lipid peroxidation, and inflammasome activation in cellular models derived from patients with multiple sclerosis.” DOI - https://doi.org/10.18632/aging.206198 Corresponding author - José Antonio Sánchez-Alcázar - jasanalc@upo.es Video interview - https://www.youtube.com/watch?v=wIV0lAHPA_M Abstract Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system (CNS). Despite advancements in managing relapsing active illness, effective treatments for the irreversible progressive decline in MS remain limited. Research employing skin fibroblasts obtained from patients with neurological disorders revealed modifications in cellular stress pathways and bioenergetics. However, research using MS patient-derived cellular models is scarce. In this study, we collected fibroblasts from two MS patients to investigate cellular pathological alterations. We observed that MS fibroblasts showed a senescent morphology associated with iron/lipofuscin accumulation and altered expression of iron metabolism proteins. In addition, we found increased lipid peroxidation and downregulation of antioxidant enzymes expression levels in MS fibroblasts. When challenged against erastin, a ferroptosis inducer, MS fibroblasts showed decreased viability, suggesting increased sensitivity to ferroptosis. Furthermore, MS fibroblasts presented alterations in the expression levels of autophagy-related proteins. Interestingly, these alterations were associated with mitochondrial dysfunction and inflammasome activation. These findings were validated in 7 additional patient-derived cell lines. Our findings suggest that the underlying stress phenotype of MS fibroblasts may be disease-specific and recapitulate the main cellular pathological alterations found in the disease such as mitochondrial dysfunction, iron accumulation, lipid peroxidation, inflammasome activation, and pro-inflammatory cytokine production.

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.

BUFFALO, NY — April 7, 2025 — A new #research paper was #published in Aging (Aging-US) on March 18, 2025, in Volume 17, Issue 3, titled “Mitochondrial oxidative stress or decreased autophagy in osteoblast lineage cells is not sufficient to mimic the deleterious effects of aging on bone mechanoresponsiveness.” Researchers from the University of Arkansas for Medical Sciences, led by first author Ana Resende-Coelho and corresponding authors Melda Onal and Maria Almeida, investigated why bones become less responsive to exercise as people age. They studied two well-known aging-related cellular changes: oxidative stress (a buildup of harmful molecules inside cells) and reduced autophagy (a slowdown in the cell's ability to clean out and recycle damaged parts) to determine whether these could explain the decline in bone strength. Their findings revealed that these changes alone are not enough to account for the reduced bone-building response seen with aging. Physical activity is known to strengthen bones by creating mechanical stress, which activates bone cells like osteocytes to promote new bone formation. However, this process becomes less effective with age, increasing the risk of bone loss and fractures in older adults. The study aimed to uncover why this response weakens over time by focusing on specific age-related changes inside bone-forming cells. “The bone response to loading is less effective with aging, but the cellular and molecular mechanisms responsible for the impaired mechanoresponsiveness remain unclear.” The research team used a well-established mouse model in which pressure was applied to the tibia, simulating the effects of exercise. As expected, bones from older mice showed a weaker response compared to those of younger mice. However, when the researchers examined younger mice genetically modified to have either high oxidative stress or impaired autophagy, as seen in aging, their bones still responded normally to mechanical loading. The researchers also found that damage to the bone's osteocyte network, a system of cells that helps sense and respond to mechanical forces, did not prevent a healthy bone-building response in mice with autophagy deficiencies. This challenges the long-standing idea that deterioration of this cell network is a main cause of age-related bone decline. These results are significant because they eliminate two widely suspected causes of the aging skeleton's reduced responsiveness to exercise. While oxidative stress and autophagy dysfunction are common in older bone, they are not solely responsible for its reduced ability to grow stronger under physical stress. The authors suggest that future studies should explore other possible factors, such as changes in energy metabolism or how bone cells communicate. Overall, this study shows that bone aging is more complex than previously thought. Protecting bone health in older adults may require new strategies that go beyond targeting oxidative stress or autophagy.

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.

Could a class of drugs that clear aging cells also help treat Alzheimer's disease? A recent study, featured as the cover for Aging (Volume 17, Issue 3), titled “Differential senolytic inhibition of normal versus Aβ-associated cholinesterases: implications in aging and Alzheimer's disease,” suggests they might—and with remarkable precision. Understanding Alzheimer's Disease Alzheimer's disease is a progressive neurological disorder that gradually steals memory, independence, and a person's sense of identity. A defining feature of Alzheimer's is the buildup of amyloid-β (Aβ) plaques—sticky protein clumps that interfere with communication between brain cells. This disruption is closely linked to changes in a group of enzymes called cholinesterases, especially acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). These enzymes normally play a vital role in regulating neurotransmitters critical for memory, learning, and cognitive function. In Alzheimer's, however, their behavior changes significantly, particularly when they interact with Aβ plaques. The Study: Exploring Senolytics for Alzheimer's Enzyme Inhibition A research team from Dalhousie University in Canada looked into whether senolytic compounds—a class of drugs that eliminate damaged, aging cells often referred to as “zombie” cells—could also target the harmful forms of cholinesterase enzymes found in Alzheimer's disease. Their goal was to see if these compounds could selectively inhibit the disease-associated versions of AChE and BChE, without affecting the healthy forms that are essential for normal brain function.

BUFFALO, NY — April 1, 2025 — A new #research paper was #published in Aging (Aging-US) on March 29, 2025, as the #cover of Volume 17, Issue 3, titled “Differential senolytic inhibition of normal versus Aβ-associated cholinesterases: implications in aging and Alzheimer's disease.” In this study, a research team from Dalhousie University, led by Sultan Darvesh, discovered that certain anti-aging compounds, known as senolytics, can block harmful brain enzymes linked to Alzheimer's disease (AD) without affecting healthy ones. Senolytics are compounds that help clear out damaged or “zombie” cells that build up with age and contribute to inflammation and tissue dysfunction. This work provides new insight into how AD-related damage can be precisely targeted, leading the way for safer treatments that protect memory and brain health in older adults. Alzheimer's disease is one of the most common causes of memory loss and dementia. A hallmark of the disease is the buildup of sticky protein clumps in the brain, known as amyloid-beta plaques. Two enzymes—acetylcholinesterase (AChE) and butyrylcholinesterase (BChE)—are found near these plaques. While these enzymes play important roles in brain function, they can also contribute to AD progression when they attach to plaques. Drugs that target these enzymes are already used to help with memory, but they often block both harmful and healthy forms, which can cause unwanted side effects. To investigate a better solution, researchers tested six compounds that are known for their anti-aging or brain-boosting properties. They wanted to know if these compounds could block only the harmful AChE and BChE enzymes forms linked to Alzheimer's disease. Using brain tissue samples from AD patients and enzyme activity assays, they discovered that compounds such as dasatinib and nintedanib, both senolytics, were able to block the forms of AChE and BChE associated with amyloid-beta plaques. These compounds did not affect normal brain enzymes, though. “We show that the selected senolytics and nootropic inhibit ChEs associated with plaques but not the enzymes associated with normal neural elements.” The study also used computer modeling to explore how these compounds interact with the enzymes. The models showed that the enzymes change shape when near plaques, making them easier for certain compounds to target. This change may explain how the drugs can selectively affect only the diseased areas of the brain. While not all compounds worked equally well, the findings offer a new strategy for treating AD. By focusing on the differences between healthy and diseased enzyme forms, researchers may be able to design more precise and effective therapies. This selective approach could improve memory, reduce inflammation, and avoid the side effects of AD's current treatments. In summary, this research opens new possibilities for treating Alzheimer's disease in a more targeted way. It also highlights how discoveries in aging and brain health can work together to create better therapies for neurodegenerative diseases.

A young woman beat leukemia; however, nine years later, she faced a different blood cancer. This rare twist, reported recently in Oncotarget, reveals an unexpected risk of bone marrow transplants and opens new questions about long-term outcomes and donor screening. Bone Marrow Transplant Bone marrow transplants, also known as hematopoietic stem cell transplants, are often lifesaving for patients with blood cancers like leukemia. These transplants replace a patient's damaged bone marrow with healthy cells from a donor, giving the body a fresh start. While this treatment can be remarkably effective, it comes with complex risks. Relapse of the original cancer is the most feared outcome. But in very rare cases, a different threat emerges; a cancer formed from the donor's cells. This condition, called donor cell–derived hematologic neoplasm (DCHN), occurs in less than 1% of cases, and it can emerge years after a transplant. The Case Report Dr. Aleksandra Mroczkowska-Bękarciak and Dr. Tomasz Wróbel from Wroclaw Medical University in Poland recently published a new DCHN case report, titled “A case report of donor cell–derived hematologic neoplasms 9 years after allogeneic hematopoietic cell transplantation,” in Volume 16 of Oncotarget.

In this installment of the Longevity & Aging Series, Dr. Julia Sidorova from the Department of Laboratory Medicine and Pathology at the University of Washington (Seattle, WA) joined host Dr. Evgeniy Galimov to discuss her co-authored research paper from Volume 16, Issue 20 of Aging (Aging-US), titled “Werner syndrome RECQ helicase participates in and directs maintenance of the protein complexes of constitutive heterochromatin in proliferating human cells.” DOI - https://doi.org/10.18632/aging.206132 Corresponding Author - Julia M. Sidorova - julias@uw.edu Video interview - https://www.youtube.com/watch?v=3yn8O-JA6GE Abstract Werner syndrome of premature aging is caused by mutations in the WRN RECQ helicase/exonuclease, which functions in DNA replication, repair, transcription, and telomere maintenance. How the loss of WRN accelerates aging is not understood in full. Here we show that WRN is necessary for optimal constitutive heterochromatin levels in proliferating human fibroblasts. Locally, WRN deficiency derepresses SATII pericentromeric satellite repeats but does not reduce replication fork progression on SATII repeats. Globally, WRN loss reduces a subset of protein-protein interactions responsible for the organization of constitutive heterochromatin in the nucleus, namely, the interactions involving Lamin B1 and Lamin B receptor, LBR. Both the mRNA level and subcellular distribution of LBR are affected by WRN deficiency, and unlike the former, the latter phenotype does not require WRN catalytic activities. The phenotypes of heterochromatin disruption seen in WRN-deficient proliferating fibroblasts are also observed in WRN-proficient fibroblasts undergoing replicative or oncogene-induced senescence. WRN interacts with histone deacetylase 2, HDAC2; WRN/HDAC2 association is mediated by heterochromatin protein alpha, HP1α, and WRN complexes with HP1α and HDAC2 are downregulated in senescing cells. The data suggest that the effect of WRN loss on heterochromatin is separable from senescence program, but mimics at least some of the heterochromatin changes associated with it.

Could the air we breathe, the food we eat, or the chemicals in our everyday environment be accelerating our aging process? A recent study published in Aging suggests that exposure to certain environmental chemicals may be linked to faster biological aging through changes in DNA. These findings could have major implications for public health and longevity. Understanding How Scientists Measure Aging at the DNA Level Aging is not just about wrinkles and gray hair—it happens at the molecular level too. Scientists use epigenetic clocks to measure biological aging, which can differ from a person's actual chronological age. These clocks track DNA methylation, a type of chemical modification that can change over time due to environmental factors like diet, pollution, and chemical exposure. Until now, there has been little research into how widespread environmental chemicals impact these aging markers. The Study: Investigating the Impact of Environmental Pollutants on Aging A research team led by first author Dennis Khodasevich and corresponding author Andres Cardenas from Stanford University, conducted an exposome-wide association study to examine how different environmental pollutants affect epigenetic aging. Using data from the National Health and Nutrition Examination Survey (NHANES), they analyzed blood and urine samples from 2,346 adults aged 50 to 84. The study measured 64 environmental chemicals, including heavy metals, pesticides, plastics, and tobacco-related compounds, to identify potential links to accelerated aging. The study titled “Exposome-wide association study of environmental chemical exposures and epigenetic aging in the national health and nutrition examination survey,” was published in Aging on February 11, 2025.

Radiation therapy or radiotherapy, is a common treatment for cancer, but its effectiveness differs across patients. A recent study published as the cover for Volume 17, Issue 2 of Aging explored why this happens. The findings provide valuable insights, particularly for brain cancers like glioblastoma (GBM) and low-grade gliomas (LGG). Understanding Glioblastoma and Low-Grade Gliomas Glioblastoma and LGG are both brain tumors, but they behave in very different ways. GBM is highly aggressive, with most patients surviving only 12 to 18 months, even with surgery, chemotherapy, and radiation therapy. LGG, on the other hand, grows more slowly, and many patients live for decades with proper care. Despite their differences, LGG and GBM are biologically linked. Some LGG tumors eventually transform into GBM, making early treatment decisions critical. Given radiation therapy's effectiveness in GBM, it has often been assumed that LGG patients would also benefit from it. However, a new study titled “Variability in radiotherapy outcomes across cancer types: a comparative study of glioblastoma multiforme and low-grade gliomas” challenges this assumption.

Imagine if a single blood test could tell clinicians in real time how successful a cancer surgery has been. A recent study from the University of Brasília, published in Oncotarget, suggests that such an approach might soon be possible. By tracking changes in cell-free DNA (cfDNA) levels before, during, and after colorectal cancer (CRC) surgery, researchers have found a potential new way to monitor tumor removal and predict patient outcomes. Cell-Free DNA and Colorectal Cancer Surgery Cell-free DNA consists of tiny fragments of genetic material that are released into the bloodstream when cells break down. In healthy individuals, these fragments come from normal cell turnover, but in cancer patients, some of this DNA originates from tumor cells. cfDNA detection has been used to track cancer progression and treatment response in diseases like lung, breast, and CRC. What had not been investigated until now was how cfDNA levels fluctuate during cancer surgery itself. Since surgery is the primary treatment for CRC, understanding how cfDNA levels change during surgical intervention could provide valuable insights into whether the tumor has been fully removed and how the patient's body reacts to the procedure. The Study: Measuring Cell-Free DNA in Real-Time In the study, titled “Assessment of cfDNA release dynamics during colorectal cancer surgery,” led by first author Mailson Alves Lopes and corresponding author Fabio Pittella-Silva, scientists analyzed ​​blood plasma samples from 30 CRC patients at three critical time points—before, during, and after surgery. Using highly sensitive genetic tests, they measured changes in cfDNA concentration to determine whether surgery had a direct impact on its release. The goal was to check whether cfDNA could serve as a biomarker for evaluating surgical effectiveness and predicting the probability of cancer recurrence.

BUFFALO, NY — February 24, 2025 — A new #researchpaper was #published in Aging (Aging-US) on January 22, 2025, in Volume 17, Issue 1, titled “EpiAge: a next-generation sequencing-based ELOVL2 epigenetic clock for biological age assessment in saliva and blood across health and disease.” The research team, experts from both industry (EpiMedTech Global, HKG Epitherapeutics Ltd) and academic institutions (McGill University, Oxford University, University of Catania, and the Research Institute-IRCCS), led by first author David Cheishvili and corresponding author Moshe Szyf, have developed EpiAgePublic, a new method to estimate biological age using only three key DNA sites in the ELOVL2 gene, a well-known marker of aging. Unlike traditional methods that require analyzing thousands of DNA regions, this approach simplifies the process while maintaining accuracy. Their findings show that EpiAgePublic performs as well as, or even better than, more complex models in predicting biological age in diverse populations. Biological age measures how fast or slow a person's body is aging. It can be different from chronological age and is influenced by genetics, lifestyle, and health conditions. Understanding biological aging can help researchers and clinicians identify age-related diseases like Alzheimer's disease and develop anti-aging treatments. However, many existing biological age tests rely on expensive and complicated processes. The EpiAgePublic model overcomes these challenges with a simple yet powerful approach. The study analyzed data from over 4,600 individuals across different health conditions, including Alzheimer's disease and HIV. It confirmed that EpiAgePublic accurately tracks aging patterns and can identify factors such as chronic illness or stress that accelerate the aging process. Importantly, the researchers demonstrated that the test works well using saliva samples, offering a convenient and non-invasive alternative to blood-based tests. This makes it easier to conduct epigenetic age testing in both clinical and research settings. “The simplicity and precision of epiAgePublic, designed for compatibility with next-generation sequencing (NGS) technologies, mark a significant step forward in the field of epigenetic research.” The ability to measure epigenetic aging with a quick and cost-effective test has significant implications for healthcare, longevity research, and personalized medicine. This method could be used in hospitals, wellness clinics, and longevity studies to track aging and evaluate the effectiveness of anti-aging interventions. It may also help clinicians detect early signs of aging-related diseases, allowing for better preventive care. Finally, the study's findings highlight the advantages of next-generation sequencing in epigenetic research, leading the way for more precise and accessible aging diagnostics. Future research will explore how this model can be expanded to other health conditions and used in routine medical practice.

BUFFALO, NY — February 19, 2025 — A new #research paper was #published by Aging (Aging-US) on January 6, 2025, in Volume 17, Issue 1, titled “The profile of oxidative stress markers (arachidonic and linoleic acid derivatives) in patients with benign prostatic hyperplasia in relation to metabolic syndrome.” A team of researchers, led by first author Weronika Ratajczak and corresponding author Olimpia Sipak from Pomeranian Medical University, examined how inflammation and metabolic health contribute to benign prostatic hyperplasia (BPH), a common condition that causes prostate enlargement in aging men, leading to urinary problems. Their findings suggest that inflammatory-related molecules in the blood may play a key role in BPH development, especially in men with metabolic syndrome—a group of conditions including obesity, high blood sugar, and high cholesterol. BPH affects millions of men as they age, making urination more difficult and sometimes painful. While age and hormonal changes are known factors, the precise causes of prostate enlargement remain unclear. This study provides new evidence that inflammation, especially lipid-derived inflammatory markers, may be a driving factor behind BPH, particularly in those with poor metabolic health. The research team analyzed blood samples from 219 men, including 144 with BPH and 75 without, measuring markers related to inflammation and oxidative stress. The results showed that men with BPH had significantly higher levels of pro-inflammatory molecules such as 12S-HETE and 5-HETE while having lower levels of anti-inflammatory substances like lipoxin A4. The imbalance was even more pronounced in men with both BPH and metabolic syndrome, indicating a possible link between poor metabolic health and worsening prostate conditions​. “Furthermore, there is mounting evidence that links the onset of inflammation with the development of prostate diseases, including benign prostatic hyperplasia and prostate cancer.” Metabolic dysfunction and chronic inflammation may not only contribute to BPH development but also exacerbate its severity. Monitoring metabolic health could play a role in reducing the risk of prostate enlargement. Future research is needed and may focus on whether anti-inflammatory treatments or lifestyle changes—such as improved diet, weight management, and exercise—could help slow the progression of BPH or reduce its symptoms​.

Imagine a simple topical treatment that could help aging skin heal faster, reducing recovery time from wounds and even improving skin quality. Scientists may have found exactly that. A recent study, published in Aging, reveals that a compound called ABT-263 can eliminate aging cells in the skin, boosting its ability to regenerate. Understanding How Aging Affects Skin Healing Aging affects the skin's structure and function, leading to a reduced ability to heal from wounds. Scientists have long suspected that senescent cells, also known as “zombie cells,” play a major role in this decline. These cells stop dividing but refuse to die, accumulating in tissues and releasing inflammatory molecules that impair the body's natural repair processes. Various studies have explored senolytics, a class of drugs designed to eliminate these aging cells and restore tissue function. While these drugs have shown promise in treating diseases like osteoporosis and fibrosis, their impact on skin regeneration and wound healing has been less studied. A new study titled “Topical ABT-263 treatment reduces aged skin senescence and improves subsequent wound healing” now suggests that a topical application of the senolytic ABT-263 could significantly improve wound healing in older individuals.

For years, breast cancer has been classified as either HER2-positive or HER2-negative, determining whether a patient could receive HER2-targeted therapies like trastuzumab (Herceptin). However, a growing body of research suggests a middle category—HER2-low breast cancer—which has led to important changes in how clinicians approach treatment. A recent review published in Oncotarget, titled “Evolving Concepts in HER2-Low Breast Cancer: Genomic Insights, Definitions, and Treatment Paradigms,” explores what this means for both patients and clinicians​.

An unexpected link between KLRG1 and PD-1, two key immune system proteins, was revealed in a study recently published in Oncotarget. This discovery could help explain why some cancer immunotherapy treatments are less effective for certain patients and lead to new therapeutic strategies. How the Immune System Fights Cancer The immune system is a powerful defense mechanism against cancer, with CD8 T cells acting as the primary soldiers. These specialized immune cells identify and destroy tumor cells. However, cancer can cleverly evade this attack by manipulating immune checkpoints—natural “breaks” on the immune system that prevent it from overreacting and damaging healthy tissue. One of the most studied checkpoints is PD-1 (Programmed Death-1), a receptor on T cells that acts as an “off switch” when activated by tumor cells. This mechanism suppresses the immune response, allowing cancer to grow without control. In response, researchers have developed treatments called PD-1 inhibitors, which block this “off switch” and keep T cells active. The Study: Investigating KLRG1 and PD-1 in Tumor-Fighting T Cells In the study titled “Anti-correlation of KLRG1 and PD-1 expression in human tumor CD8 T cells,” Dr. Steven A. Greenberg from Harvard Medical School analyzed publicly available gene expression data from various cancer types, including lung cancer, melanoma, and colorectal cancer. His goal was to identify immune-related proteins that could complement existing therapies, such as PD-1 inhibitors.

Scientists have discovered that a genetic variant called KIT M541L may play an important role in a rare immune disorder known as #mastocytosis. The findings may help explain why some #patients develop more severe forms of the disease. Understanding Mastocytosis Mastocytosis is a condition where the body produces too many mast cells. These cells are part of the immune system and help the body fight infections, but in excess, they release chemicals that can cause itching, swelling, and even serious organ damage. There are two main types of mastocytosis. The first is cutaneous mastocytosis, which mostly affects the skin. The second is systemic mastocytosis, a more serious form where mast cells build up in internal organs like the liver, spleen, and bone marrow. The disease is linked to mutations in the KIT gene, which regulates mast cell growth. The most studied mutation is KIT D816V, but recent research has highlighted another variant, KIT M541L. The Study: Impact of KIT M541L Variant A team of researchers at the National Institutes of Health (NIH), led by first author Luisa N. Dominguez Aldama and corresponding author Melody C. Carter, aimed to better understand the prevalence and impact of the KIT M541L genetic variant in mastocytosis patients. The study published in Oncotarget on July 22, 2024, titled “Prevalence and impact of the KIT M541L variant in patients with mastocytosis,” examined the presence of the KIT M541L gene variant in 100 patients with mastocytosis, both adults and children, alongside 500 healthy individuals. By comparing these two groups, the researchers wanted to see if there was a relation between the KIT M541L variant and mastocytosis severity.

Would you take a test to find out your cancer risk? At-home genetic testing makes it easy, but experts warn that these tests may create more harm than good. A New Approach to Genetic Testing Genetic testing has traditionally been performed under the supervision of healthcare providers, with genetic counseling to help patients navigate their results. This approach ensures that individuals receive proper guidance, reducing the emotional and practical challenges of interpreting complex genetic information. In September 2023, the United States Food and Drug Administration (FDA) approved a new test called the Invitae Common Hereditary Cancers Panel. This test checks for changes in 48 genes linked to hereditary cancers, including breast, ovarian, and Lynch syndrome-related cancers. What makes it different is that it can be ordered online and taken at home with no doctor required. While the convenience of these tests is appealing, health experts have raised serious concerns. An editorial titled “Pitfalls and Perils from FDA-Approved Germ-line Cancer Predisposition Tests,” authored by Dr. Wafik S. El-Deiry, Editor-in-Chief of Oncotarget, and Dr. Eli Y. Adashi, both from Brown University, highlights the potential risks of using these tests without professional guidance.
