A #Research paper recently #Published in Volume 18 of Aging, titled “Slowing intervertebral disc aging in mice through long-term systemic treatment with the senolytic BCL-2/BCL-xL proteolysis targeting chimera (PROTAC) 753b,” examines whether the senolytic PROTAC 753b can slow age-related intervertebral disc degeneration (IDD) in mice. Long-term systemic treatment with 753b reduced key features of disc degeneration in 22-month-old male mice, including matrix breakdown, loss of disc aggrecan, age-related structural changes, and inflammatory markers such as IL-6 and TNFα. These benefits, however, were not observed in female mice, highlighting potential sex-based differences in the role of cellular senescence in IDD and the response to senolytic therapies.

BUFFALO, NY — August 12, 2026 — A new #research paper was #published in Volume 18 of Aging on July 27, 2026, titled “Transcriptomic aging clock analysis identifies key genes in opioid dependence.” The study was led by first author Hai Duc Nguyen from the Division of Microbiology, Tulane National Biomedical Research Center, Tulane University. The corresponding author is Woong-Ki Kim, who is affiliated with the Division of Microbiology, Tulane National Biomedical Research Center, Tulane University, and the Department of Microbiology and Immunology at Tulane University School of Medicine. Opioid dependence is a chronic and relapsing condition associated with substantial health and societal burdens. Chronic opioid exposure can affect neuronal signaling, immune function, metabolism, and other biological processes, yet the molecular mechanisms underlying dependence remain incompletely understood. Increasing evidence also suggests that substance use disorders may be associated with molecular changes related to aging, raising questions about how chronic opioid exposure interacts with age-dependent processes in the brain. To investigate these relationships, the researchers conducted an in silico study integrating three complementary approaches: RNA sequencing-based transcriptomic profiling, transcriptomic aging-clock modeling, and analysis of previously published genome-wide association studies (GWAS). The transcriptomic analysis used a publicly available brain RNA-seq dataset containing 42 samples—21 healthy controls and 21 individuals with opioid dependence—while the genetic analysis incorporated findings from six independent GWAS.

BUFFALO, NY — August 10, 2026 — A new #essay was #published in Volume 18 of Aging on August 6, 2026, titled “Misha Blagosklonny: a life of ideas.” The article was written by Aging Editorial Board member David Gems from the Institute of Healthy Ageing and Research Department of Genetics, Evolution and Environment, University College London, United Kingdom, along with Aging Editor-in-Chief Marco Demaria from the European Research Institute for the Biology of Ageing (ERIBA), University Medical Center Groningen (UMCG), University of Groningen, the Netherlands. Rather than presenting new experimental findings, the essay examines the life, scientific contributions, and lasting influence of Mikhail (“Misha”) Blagosklonny, whose ideas had a major influence on modern thinking about the biological mechanisms of aging. Dr. Blagosklonny was trained as a physician and experimental scientist before building an influential career in oncology and aging research after moving to the United States. His work combined cancer biology with theoretical biogerontology, leading to the proposal that aging is driven not primarily by the passive accumulation of molecular damage, but by developmental and growth-related programs that continue beyond their beneficial period. Through what he described as conceptual research, Misha synthesized evidence from diverse experimental studies to generate new hypotheses about aging and reinterpret existing biological observations. A central theme of the essay is Dr. Blagosklonny's development of the hyperfunction theory of aging. Building on observations that persistent activation of the mechanistic target of rapamycin (mTOR) pathway can drive cellular senescence, he proposed that many features of aging arise from the continued activity of biological programs that promote growth and reproduction earlier in life. Rather than viewing aging as an adaptive genetic program, Misha argued that it represents a quasi-program—a genetically determined continuation of normal developmental processes that become harmful later in life. This framework provided a mechanistic explanation linking evolutionary concepts such as antagonistic pleiotropy with molecular pathways that regulate growth, metabolism, and cellular senescence.

BUFFALO, NY — August 6, 2026 — A new #research perspective was #published in Volume 18 of Aging on July 24, 2026, titled “A brief history of the hyperfunction theory of aging and future directions.” The article was written by João Pedro de Magalhães from the Genomics of Ageing and Rejuvenation Lab, Department of Inflammation and Ageing, College of Medicine and Health, University of Birmingham, United Kingdom. Rather than presenting new experimental findings, the perspective examines the historical development of the hyperfunction theory of aging, reviews evidence supporting programmatic mechanisms of aging, and discusses future directions for understanding why organisms age and how aging might eventually be modified. For decades, most aging research has been dominated by the idea that aging results primarily from the gradual accumulation of molecular damage, including DNA damage, oxidative stress, mitochondrial dysfunction, and protein deterioration. In contrast, the hyperfunction theory proposes that aging is driven largely by developmental and growth programs that continue operating beyond their beneficial period. Rather than being intentionally programmed, aging is viewed as a consequence of biological pathways that promote growth and reproduction early in life but become harmful when they continue later in adulthood. The perspective traces the historical roots of these ideas from early theories proposed in the nineteenth century through Clive McCay's pioneering caloric restriction experiments and George Williams' concept of antagonistic pleiotropy. Particular attention is given to the contributions of the late Mikhail Blagosklonny, whose hyperfunction theory proposed that aging results from “quasi-programs”—developmental processes that fail to switch off after their normal biological role has ended. The author argues that this framework provides a mechanistic explanation linking evolutionary theory with many biological features of aging.

BUFFALO, NY — August 5, 2026 — A new #research paper was #published in Volume 18 of Aging on July 23, 2026, titled “Adipo-neuroinflammation, cognitive impairment and surrogate markers of cardiovascular risk in patients with Metabolic Dysfunction Associated Steatotic Liver Disease (MASLD).” The study was led by co-first authors Gaetano Pacinella from the University of Palermo, and the Internal Medicine and Stroke Care Ward, Policlinico “P. Giaccone”, Palermo, and Alessandro Del Cuore from the same institutions. Gaetano Pacinella also served as the corresponding author. Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as nonalcoholic fatty liver disease, is increasingly recognized as a systemic condition that extends beyond the liver. People with MASLD have an elevated risk of cardiovascular disease, cognitive decline, and other metabolic complications, yet the biological mechanisms connecting these conditions remain incompletely understood. In this study, researchers investigated whether lipocalin-2 (LCN2), a protein involved in inflammatory and metabolic signaling, is associated with early vascular dysfunction, cognitive impairment, and cardiovascular risk in patients with MASLD.

Heart failure remains one of the leading causes of hospitalization among older adults worldwide. During episodes of acute decompensated heart failure (ADHF), excess fluid builds up in the lungs and body, making breathing difficult and increasing the risk of serious complications. Although intravenous loop diuretics such as furosemide are the standard treatment for relieving congestion, many patients continue to experience persistent inflammation, ongoing cardiac remodeling, and worsening heart function despite therapy. A research paper published in Volume 18 of Aging titled “Effects of intravenous furosemide plus small-volume hypertonic saline solutions on inflammatory, remodelling markers and epigenetics signatures of patients with congestive acute decompensated heart failure (ADHF),” investigated whether combining intravenous furosemide with small volumes of hypertonic saline solution (HSS) could improve biological markers associated with heart failure compared with furosemide alone.

BUFFALO, NY — August 3, 2026 — A new #research paper was #published in Volume 18 of Aging on July 17, 2026, titled “Selective targeting of cancer and senescence via shared metabolic shifts extends lifespan of old mice.” The study was led by first author Zachery R. Robinson, and corresponding author and Aging editorial board member Irina M. Conboy, both from the Department of Bioengineering and QB3 Institute, University of California, Berkeley. The researchers developed a new combination therapy that selectively targets both cancer cells and senescent cells by exploiting metabolic vulnerabilities shared by these two cell types. In laboratory studies and aged mice, the treatment selectively eliminated senescent cells and reduced cancer cell viability while improving physical performance and extending lifespan without significant toxicity to healthy tissues. Cancer and aging are closely linked. As people age, senescent cells accumulate throughout the body. Although these cells no longer divide, they remain metabolically active and release inflammatory molecules known as the senescence-associated secretory phenotype (SASP), which contributes to chronic inflammation, tissue dysfunction, and tumor progression. Existing therapies such as the BCL-2/BCL-xL inhibitor navitoclax (ABT-263) can eliminate both cancer cells and senescent cells but require doses that frequently cause thrombocytopenia, a potentially serious reduction in platelet counts that has limited their clinical use.

BUFFALO, NY — July 30, 2026 — A new #research perspective was #published in Volume 18 of Aging on July 16, 2026, titled “Towards integration of healthspan strategies into the Italian National Health Service.” The article was led by co-first authors Nicola Marino, affiliated with the AEON Foundation and the Women's Brain Foundation, and Matteo Fiore from the University of Bologna, with both serving as corresponding authors. Rather than presenting new clinical trial results, the authors propose a prevention-focused framework for the staged, evidence-based evaluation and integration of healthspan strategies into Italy's National Health Service (Servizio Sanitario Nazionale, SSN) to help address the challenges of an aging population. Italy has one of the oldest populations in the world. Although life expectancy has continued to increase, many older adults spend a substantial portion of those additional years living with chronic disease, disability, or reduced physical and cognitive function. The authors describe this mismatch as the lifespan–healthspan divide and argue that healthcare systems should increasingly focus not only on helping people live longer, but also on extending the years they remain healthy and functionally independent. To address this challenge, the authors outline the concept of longevity medicine, describing it as a prevention-oriented, life-course framework rather than a new medical specialty. The approach integrates principles from geroscience, preventive medicine, and personalized healthcare with the goal of identifying age-related risks earlier and promoting healthy aging before chronic diseases and functional limitations accumulate. At the same time, the paper emphasizes that many emerging tools—including biological-age biomarkers, multi-omic profiling, wearable sensor data, and artificial intelligence-based risk stratification—remain exploratory and should not be adopted routinely until they demonstrate clear clinical utility, cost-effectiveness, and meaningful benefits for patients.

BUFFALO, NY — July 27, 2026 — A new #research paper was #published in Volume 18 of Aging on July 13, 2026, titled “Slowing intervertebral disc aging in mice through long-term systemic treatment with the senolytic BCL-2/BCL-xL proteolysis targeting chimera (PROTAC) 753b.” The study was led by first author Peter G. Alexander from the Ferguson Laboratory for Spine Research, Department of Orthopaedic Surgery, University of Pittsburgh School of Medicine, and corresponding author Nam Viet Vo from the same institution. Intervertebral disc degeneration is a leading cause of chronic low back pain and disability. As discs age, they lose important structural components, become less able to absorb mechanical stress, and accumulate senescent cells—dysfunctional cells that stop dividing but continue releasing inflammatory molecules that contribute to tissue degeneration. Senolytic therapies, which selectively eliminate these cells, have emerged as a promising strategy to slow age-related diseases. In this study, researchers evaluated PROTAC 753b, a next-generation senolytic designed to target the anti-apoptotic proteins BCL-2 and BCL-xL while reducing the platelet toxicity associated with earlier drugs in this class. The researchers treated 16-month-old male and female mice with PROTAC 753b for six months and evaluated their intervertebral discs at 22 months of age using histology, molecular analyses, and measurements of inflammatory markers. The treatment significantly improved several measures of intervertebral disc health in aged male mice, preserving the extracellular matrix protein aggrecan and reducing matrix metalloproteinase (MMP)-mediated aggrecan breakdown, a hallmark of disc degeneration. In contrast, female mice showed little overall improvement, revealing a sex-specific response to treatment.

BUFFALO, NY — July 23, 2026 — A new #research paper was #published in Volume 18 of Aging on July 8, 2026, titled “TM4SF1 is a surface marker of senescent pancreatic β-cells.” The study was led by first author Ana Beathriz Leite Lorente from Joslin Diabetes Center and Harvard Medical School, and São Paulo State University (UNESP), Brazil, and corresponding author Cristina Aguayo-Mazzucato from Joslin Diabetes Center and Harvard Medical School. Type 2 diabetes is characterized by insulin resistance and the progressive loss of pancreatic β-cell function. With aging and metabolic stress, senescent β-cells accumulate within the pancreas, producing less insulin while releasing inflammatory signals that contribute to disease progression. Although eliminating these dysfunctional cells has emerged as a promising therapeutic strategy, a major challenge has been identifying markers that distinguish senescent β-cells from healthy cells with sufficient precision. This study identifies transmembrane 4 L six family member 1 (TM4SF1) as a highly selective surface marker of senescent β-cells, providing a promising candidate for the future development of more selective therapies for type 2 diabetes. In this study, the researchers searched for cell-surface proteins that specifically identify senescent β-cells. Using RNA sequencing, flow cytometry, immunofluorescence, and analyses of both mouse and human pancreatic tissue, they compared TM4SF1 with the previously established senescence marker urokinase-type plasminogen activator receptor (uPAR/PLAUR). Their findings showed that TM4SF1 is expressed predominantly in senescent β-cells while exhibiting much lower expression in non-senescent β-cells and other tissues, making it a more β-cell-specific surface marker than uPAR.

Coordinating both hands is something most people take for granted. Everyday activities such as buttoning a shirt, preparing a meal, driving, or using a knife and fork all depend on the brain's ability to precisely control movements on both sides of the body. As people age, however, these tasks often become more difficult, especially when they require both hands to perform different movements at the same time.

BUFFALO, NY — July 21, 2026 — A new #research paper was #published in Volume 18 of Aging on July 6, 2026, titled “Inhibition of peroxisomal protein PRX-11 promotes longevity in Caenorhabditis elegans via enhancements to mitochondria.” The study was authored by Yash Flora, Dhriti Shastri, Kathryn R. DeLeo, and K. Adam Bohnert from the Department of Biological Sciences, Louisiana State University. Aging is accompanied by the gradual decline of many cellular structures that help maintain healthy tissues and organs. Among these are peroxisomes, which play essential roles in breaking down toxic molecules and metabolizing lipids, and mitochondria, which generate most of the cell's energy. Although these organelles work closely together, little has been known about how changes in one influence the aging of the other. This new study reveals that preserving peroxisomes helps maintain healthier mitochondria and extends lifespan in the nematode Caenorhabditis elegans, providing new insight into how communication between cellular organelles influences aging. In this study, the researchers investigated the function of PRX-11, a peroxisomal protein involved in peroxisome division. Previous work from the group showed that reducing PRX-11 activity prevents the age-related degradation of peroxisomes through a process known as pexophagy and increases lifespan. The new study explored why preserving peroxisomes produces these beneficial effects and found that maintaining peroxisomes also preserves mitochondrial health during aging. The researchers found that animals with reduced PRX-11 activity retained long, interconnected mitochondrial networks that resembled those seen in young adults, whereas normal aging was associated with progressive mitochondrial fragmentation. These preserved mitochondria also accumulated less calcium, generated lower levels of oxidative stress, maintained higher ATP-to-ADP ratios, and were associated with improved locomotor function in older animals. Together, these findings indicate that preventing age-related peroxisome loss supports multiple aspects of mitochondrial function during aging.

BUFFALO, NY — July 16, 2026 — A new #research paper was #published in Volume 18 of Aging on July 1, 2026, titled “Senescent cells accumulate lipid droplets.” The study was led by first author Noa Rachmian-Cooper and corresponding author Valery Krizhanovsky from the Department of Molecular Cell Biology, Weizmann Institute of Science, Rehovot, Israel. Cellular senescence is a natural biological process in which damaged or stressed cells permanently stop dividing while remaining metabolically active. Although senescence helps suppress tumor formation and supports normal processes such as tissue repair and development, senescent cells accumulate with age and contribute to chronic inflammation and numerous age-related diseases, including cancer, cardiovascular disease, and Alzheimer's disease. While many of the biological effects of senescent cells have been linked to inflammatory signaling, much less has been understood about the metabolic changes that accompany senescence. In this study, the researchers investigated how cellular metabolism changes during senescence, with a particular focus on lipid metabolism. Using comprehensive metabolic profiling of human fibroblasts, they discovered that senescent cells accumulate high levels of triacylglycerols—the major precursors of lipid droplets—alongside increased glycolytic activity. Additional laboratory experiments confirmed that senescent cells contain significantly more lipid droplets than actively dividing cells.

BUFFALO, NY — July 13, 2026 — A new #review was #published in Volume 18 of Aging on June 26, 2026, titled “Hormonal dimorphism in sarcopenia disease.” The review was led by first author Romain Menard and corresponding author Romain Madelaine from the MDI Biological Laboratory, Kathryn W. Davis Center for Regenerative Biology and Aging, Bar Harbor, Maine, USA. Sarcopenia—the progressive loss of skeletal muscle mass, strength, and physical function with aging—is one of the leading causes of frailty and disability in older adults. Although the condition affects millions of people worldwide and has been recognized as a disease by the World Health Organization since 2016, treatment options remain largely limited to exercise and nutritional interventions, with no approved medications specifically targeting the disease. Growing evidence now suggests that one reason for this limited success is that sarcopenia develops through distinct biological mechanisms in women and men. In this comprehensive review, the authors examine how biological sex influences the hormonal mechanisms underlying muscle aging. They focus on three peptide hormones—apelin, insulin, and oxytocin—and describe how age-related changes in these interconnected signaling networks contribute to muscle decline through distinct biological pathways in women and men. According to the review, women often experience an abrupt decline in muscle health during menopause as estrogen levels fall rapidly. This hormonal transition disrupts apelin signaling, accelerates insulin resistance, reduces oxytocin-mediated muscle regeneration, and impairs the function of satellite cells, the muscle stem cells responsible for repair and regeneration. In contrast, men generally undergo a slower, more gradual decline in muscle function that parallels progressive reductions in testosterone, resulting in different patterns of hormonal dysregulation and disease progression. The review also highlights the central roles of apelin, insulin, and oxytocin in maintaining healthy skeletal muscle. Together, these hormones regulate muscle metabolism, glucose utilization, mitochondrial function, protein homeostasis, inflammation, and satellite-cell activity through overlapping signaling pathways. Disruption of this hormonal network during aging is proposed to contribute to impaired muscle repair, reduced metabolic function, chronic inflammation, and progressive muscle loss.

BUFFALO, NY — July 7, 2026 — A new #review was #published in Volume 18 of Aging on June 22, 2026, titled “The multifaceted inducers of cellular senescence.” The review was led by first author Hilah Gal and corresponding author Valery Krizhanovsky from the Department of Molecular Cell Biology, Weizmann Institute of Science, Rehovot, Israel. Cellular senescence is a fundamental biological process in which damaged or stressed cells permanently stop dividing while remaining metabolically active. This response plays an essential role in suppressing tumor formation, supporting embryonic development, facilitating wound healing, and maintaining tissue integrity. However, as people age, senescent cells accumulate because they are no longer efficiently cleared by the immune system. Their persistence contributes to chronic inflammation, tissue dysfunction, cancer, and many age-related diseases. In this comprehensive review, the authors examine the diverse biological stimuli that trigger cellular senescence and describe how seemingly different stimuli ultimately converge on common molecular pathways that establish stable growth arrest. Rather than viewing senescence as a single process, the review emphasizes its remarkable biological diversity and the importance of understanding how different initiating events shape distinct senescent cell phenotypes. The review discusses several major biological inducers of cellular senescence. One of the best-established mechanisms is telomere attrition, in which repeated cell division gradually shortens chromosome ends until they trigger a persistent DNA damage response. Other important stimuli include direct DNA damage caused by ionizing radiation, ultraviolet light, chemotherapy, and oxidative injury, all of which activate cellular pathways that permanently halt proliferation.

As people live longer, maintaining good health is becoming just as important as extending lifespan. While chronological age simply reflects the number of years a person has lived, biological age measures how well the body is functioning and may better predict future health. Researchers have increasingly focused on lifestyle factors that may slow biological aging, and diet has emerged as one of the most promising. A research paper published in Volume 18 of Aging titled “Plant-based dietary patterns are associated with slower epigenetic aging,” investigated whether diets emphasizing plant foods are associated with slower biological aging as measured by DNA methylation-based epigenetic clocks.

BUFFALO, NY — July 6, 2026 — A new systematic #review was #published in Volume 18 of Aging on June 18, 2026, titled “Life expectancy and causes of death in classical laminopathic progeroid syndromes: systematic review with individual-patient data synthesis.” The study was led by co-first authors Carlos López-Vila, Manuel García-Cordeiro, and Luís Estévez-Martínez from the University of Santiago de Compostela, and corresponding author David Araújo-Vilar from the University of Santiago de Compostela and the University Clinical Hospital of Santiago de Compostela, Spain. Classical laminopathic progeroid syndromes are among the rarest inherited disorders known. Caused by mutations affecting the LMNA gene or the ZMPSTE24 enzyme, these conditions lead to premature aging, severe multisystem disease, and markedly shortened life expectancy. Although Hutchinson-Gilford progeria syndrome (HGPS), mandibuloacral dysplasia (MAD), and restrictive dermopathy (RD) all belong to this group, reliable information about survival and causes of death for each disorder has remained limited because most published reports describe only individual patients or small case series. In this study, researchers performed a comprehensive systematic review and individual-patient data analysis to date of classical laminopathic progeroid syndromes. Following PRISMA guidelines, they analyzed data from 169 published studies together with two additional genetically confirmed institutional cases, creating a cohort of 158 genetically confirmed patients for the primary survival analysis. By examining individual patient records rather than pooled summaries, the investigators were able to compare survival patterns and causes of death across each disease subtype with greater precision.

BUFFALO, NY — July 1, 2026 — A new #review was #published in Volume 18 of Aging on June 11, 2026, titled “Age-related dysfunctions of the neuroendocrine axes in nonhuman primates with depression-like and anxious behavior.” The review, dedicated to the late Dr. Mikhail (Misha) Blagosklonny, was written by Nadezhda D. Goncharova from the Kurchatov Complex of Medical Primatology, National Research Center “Kurchatov Institute,” Adler, Sochi, Russian Federation. As people grow older, their risk of developing stress-related disorders—including depression, metabolic disease, cardiovascular disease, cognitive decline, and neurodegenerative conditions—increases substantially. However, not everyone ages in the same way. Some individuals appear more resilient to stress, while others develop endocrine and metabolic disturbances that may accelerate aging and disease. Understanding the biological mechanisms behind these differences could help identify people at greater risk and support more personalized approaches to healthy aging. In this review, the author summarizes decades of experimental research investigating how aging affects two major neuroendocrine systems—the hypothalamic-pituitary-adrenal (HPA) axis and the hypothalamic-pituitary-thyroid (HPT) axis—in nonhuman primates displaying either typical adaptive behavior or depression-like and anxiety-like behavior. Because rhesus monkeys closely resemble humans in their physiology, endocrine function, and behavior, they provide a valuable translational model for studying age-related changes that are difficult to examine in people. The research shows that older monkeys with depression-like and anxiety-like behavior develop more pronounced dysfunction of the HPA axis than animals with standard behavior. These animals exhibited impaired negative feedback regulation, higher evening and nighttime cortisol levels, increased responses to acute stress, and greater activation of stress-related hormonal pathways. Together, these findings suggest impaired regulation of stress responses during aging. The review also describes important age-related alterations in thyroid function. Older animals with depression-like and anxiety-like behavior showed lower thyroxine secretion, diminished thyroid responsiveness to hormonal stimulation, and evidence of impaired thyroid gland function. These endocrine changes were accompanied by greater insulin resistance, altered triglyceride metabolism, and reduced insulin secretion in overweight animals, indicating that stress-related neuroendocrine dysfunction may extend well beyond the brain. Importantly, the findings suggest that behavioral characteristics may influence how endocrine systems age. Rather than experiencing identical biological changes over time, individuals with greater vulnerability to stress may develop more severe hormonal disturbances that contribute to age-related disease.

BUFFALO, NY — June 29, 2026 — A new #review was #published in Volume 18 of Aging on May 30, 2026, titled “The love and hate relationship between cellular senescence and stemness.” The review was led by first author Angelos Papaspyropoulos and corresponding author Vassilis G. Gorgoulis from the National and Kapodistrian University of Athens and the Biomedical Research Foundation of the Academy of Athens, Greece. Cellular senescence and stemness have traditionally been viewed as biological opposites. Senescent cells permanently stop dividing in response to cellular stress, helping prevent the spread of damaged cells, while stem cells maintain tissue repair by continuously renewing themselves and generating specialized cells. However, growing evidence suggests that the relationship between these two biological processes is far more complex and depends on the tissue type, physiological conditions, and disease context. In this review, the authors summarize recent research examining how senescence and stemness interact across normal tissues, aging, regeneration, and cancer. Rather than always opposing one another, the two processes can either suppress or reinforce each other depending on the biological setting. Under normal physiological conditions, senescence often limits stem cell activity. The review highlights studies showing that excessive senescence can impair the regenerative capacity of mesenchymal stem cells, muscle satellite cells, dental pulp stem cells, and pancreatic β-cell progenitors. In several experimental models, reducing senescence restored stem cell function and improved tissue regeneration. At the molecular level, multiple signaling pathways contribute to this balance, including the p53/p21 and p16INK4A/RB pathways, mTOR signaling, Wnt/β-catenin signaling, and the senescence-associated secretory phenotype (SASP). These pathways help determine whether cells maintain regenerative potential or enter a stable senescent state. The review also emphasizes that the relationship changes dramatically in cancer. In many tumors, senescent cells can promote the emergence of cancer stem cells through inflammatory signals released as part of the SASP or through cells escaping from the senescent state. This interaction has been reported in several malignancies, including B-cell lymphoma, liver cancer, colon cancer, lung cancer, and breast cancer, where stem cell-like properties may contribute to tumor progression, metastasis, and resistance to therapy.

BUFFALO, NY — June 25, 2026 — A new #research paper was #published in Volume 18 of Aging on May 29, 2026, titled “Short-term responsiveness of DNA methylation–based aging biomarkers to a multimodal intervention comprising exercise and dietary guidance involving daily consumption of yogurt containing Bifidobacterium longum BB536: an exploratory randomized controlled trial.” The study, selected as our Editors' Choice, was led by first author Tatsuki Nishimura and corresponding author Yukihiro Hishida from the R&D Division of Morinaga Milk Industry Co., Ltd., Japan. As researchers continue searching for practical ways to promote healthy aging, increasing attention has focused on interventions that target multiple biological pathways simultaneously. While exercise and healthy eating are widely recognized as important components of healthy aging, scientists are also investigating whether specific dietary components and gut microbes may influence biological aging processes measurable at the molecular level. In this study, researchers evaluated whether a 12-week lifestyle program could affect DNA methylation–based biomarkers of aging in overweight men aged 50 years and older. The intervention combined individualized exercise guidance, dietary counseling, and daily consumption of yogurt containing Bifidobacterium longum BB536, a probiotic strain that has previously been linked to beneficial effects on inflammation and gut health. The randomized controlled trial enrolled 48 participants, who were assigned either to the intervention group or to a control group that maintained their usual lifestyle habits. Participants in the intervention group received dietary counseling focused on reducing overeating, exercise guidance encouraging regular walking or stepper-based activity, and a daily serving of yogurt containing Bifidobacterium longum BB536. To assess biological aging, the investigators measured several DNA methylation–based aging biomarkers before and after the 12-week intervention. Particular attention was given to DunedinPACE, an epigenetic measure designed to estimate the current pace of biological aging rather than biological age itself.

BUFFALO, NY — June 23, 2026 — A new #research paper was #published in Volume 18 of Aging on May 28, 2026, titled “p38MAP kinase regulates senescence in human iPS-derived myocytes.” The study was led by first author Hiroki Sato and corresponding author Ryuichiro Sato from The University of Tokyo, along with corresponding author Makoto Shimizu from The University of Tokyo and Ochanomizu University. As people age, skeletal muscle gradually loses strength, mass, and function, contributing to frailty, reduced mobility, and an increased risk of falls. Although cellular senescence is widely recognized as a major driver of aging, the mechanisms that promote aging within mature muscle fibers remain poorly understood. In this study, researchers developed a human cell-based model to investigate how senescence develops in skeletal muscle cells and identified a signaling pathway that appears to play a central role in the process. The research team used human induced pluripotent stem cell (iPSC)-derived myocytes, specialized muscle cells generated from stem cells. To mimic age-related cellular damage, the investigators exposed the cells to low-dose X-ray irradiation, which induced DNA damage without causing extensive cell death. The treated muscle cells developed several characteristics commonly associated with aging. They exhibited muscle fiber atrophy, reduced contractile activity, and increased expression of p21, a well-established marker of cellular senescence. The researchers also observed elevated production of senescence-associated secretory phenotype (SASP) factors, inflammatory and extracellular signaling molecules that are commonly released by senescent cells. To better understand the molecular changes involved, the investigators performed proteomic, transcriptomic, and functional analyses. These studies revealed activation of p38 mitogen-activated protein kinase (p38MAPK), a signaling pathway previously linked to cellular stress responses and aging in other tissues. Further experiments demonstrated that inhibiting p38MAPK partially attenuated several senescence-associated features in the muscle cells. Treatment with p38MAPK inhibitors reduced muscle fiber atrophy, improved contractile function, and suppressed the expression of several senescence-associated factors. Conversely, activating p38MAPK promoted aging-like changes in the cells, further supporting its role in regulating muscle cell senescence. The study also identified activation of an integrin–FAK/SRC–p38MAPK signaling axis following DNA damage. According to the authors, this pathway may help explain how cellular stress is translated into long-term functional decline in skeletal muscle. Importantly, the findings were supported by analyses of human muscle aging datasets, which showed increased activity of MAPK signaling, focal adhesion pathways, and cytokine-related signaling in older skeletal muscle tissue.

As people live longer, maintaining mental well-being has become an increasingly important part of healthy aging. While regular physical activity is known to support both physical and psychological health, many older adults face barriers that make traditional exercise programs difficult to sustain. Researchers have therefore been exploring new approaches that combine physical activity with enjoyment, social interaction, and cognitive engagement. A review published in Volume 18 of Aging titled “What are the effects of exergames on the mood states of older people? A systematic review of experimental studies, impacts on mental health and recommendations,” examined whether exergames—video games that require physical movement to play—can improve mood and mental health in older adults. The study was led by authors from the Laboratory of Sport and Exercise Psychology, Human Movement Sciences Graduate Program, College of Health and Sport Science of the Santa Catarina State University (UDESC) in Florianópolis, Brazil.

BUFFALO, NY — June 18, 2026 — A new #research paper was #published in Volume 18 of Aging on May 26, 2026, titled “Early-life determinants of cardiometabolic outcomes and accelerated biological ageing in Colombia.” The study was led by first and corresponding author Juan Carlos Rivillas from the Department of Epidemiology and Biostatistics, MRC Centre for Environment and Health, School of Public Health, Imperial College London, United Kingdom. Experiences during childhood can shape health for decades. Adverse childhood experiences (ACEs), such as emotional abuse, domestic violence, food insecurity, poor health, and forced displacement, have long been linked to chronic disease. However, less is known about how these early-life hardships may influence biological aging itself. In this study, researchers examined whether childhood adversity is associated with cardiometabolic disease and accelerated biological aging among older adults in Colombia. The investigators analyzed data from 3,385 adults aged 60 years and older who participated in the nationally representative SABE-Colombia study. Five forms of childhood adversity experienced before age 15 were evaluated: emotional abuse, domestic violence, poor childhood health, food scarcity, and forced migration related to Colombia's armed conflict. Biological aging was estimated using the Klemera-Doubal Method for Biological Age, a biomarker-based measure that compares biological age with chronological age.

BUFFALO, NY — June 16, 2026 — A new #research paper was #published in Volume 18 of Aging on May 22, 2026, titled “Systemic cancer risk profile in neovascular age-related macular degeneration: insights into shared aging-related mechanisms from a nationwide population-based study.” The study was led by first author Hyeong Min Kim and corresponding author Hyewon Chung from Konkuk University College of Medicine and Konkuk University Medical Center in Seoul, Republic of Korea. Neovascular age-related macular degeneration (nAMD) is one of the leading causes of severe vision loss in older adults. Although the disease primarily affects the retina, researchers increasingly recognize that it may reflect broader biological processes associated with aging, including chronic inflammation, vascular dysfunction, and immune dysregulation. These same mechanisms have also been implicated in the development of several cancers, raising questions about whether the two conditions may be biologically connected. To explore this possibility, investigators analyzed data from the Korean National Health Insurance Service, one of the world's largest population-based healthcare databases. The study included 334,091 individuals aged 50 years and older, including 83,742 patients with nAMD and 250,349 matched controls without the disease. Participants were followed for up to 10 years, allowing researchers to evaluate both overall cancer incidence and risks for specific cancer types. The analysis revealed that individuals with nAMD had a modest but statistically significant increase in overall cancer risk compared with matched controls. However, the increased risk was not observed across all cancers. Instead, patients with nAMD showed elevated risks for several specific malignancies, including thyroid, kidney, pancreatic, lung, bladder, and prostate cancers, while no significant associations were found for many other cancer types.

BUFFALO, NY — June 11, 2026 — A new #meetingreport was #published in Volume 18 of Aging on May 14, 2026, titled “Foundations of Gerophysics.” The report was led by corresponding authors Maximilian Unfried and Brian K. Kennedy from the National University of Singapore. Aging is often studied through biology, genetics, and medicine. Yet despite tremendous advances, many fundamental questions remain unanswered: Why do organisms age at different rates? Why does resilience decline over time? And can the trajectory of aging be predicted before disease develops? Researchers participating in the inaugural Global Conference on Gerophysics explored whether answering these questions may require integrating biology with the quantitative principles of physics. Held in Singapore on March 5–6, 2025, the conference brought together 160 researchers from physics, biology, computation, and medicine and featured 31 speakers from institutions around the world. The meeting focused on developing a predictive and testable science of aging by applying concepts from dynamical systems, thermodynamics, network theory, stochastic processes, and artificial intelligence to biological aging.

BUFFALO, NY — June 10, 2026 — A new #research paper was #published in Volume 18 of Aging on May 18, 2026, titled “Transcriptional programs diverge in aging mouse and human skeletal muscle.” The study was led by co-first authors Charles D. Hwang and Siti Rahmayanti and corresponding author Indranil Sinha from Brigham and Women's Hospital, Harvard University. Aging is widely associated with the gradual loss of muscle mass, strength, and physical function. Much of what scientists know about these changes comes from studies in laboratory mice, which are frequently used to investigate the biological mechanisms of aging and to identify potential therapeutic targets. However, an important question remains: how closely do aging-related changes in mouse muscle reflect what actually occurs in humans? To address this question, researchers performed a detailed comparison of gene expression patterns in skeletal muscle from young and old mice and humans. The team analyzed RNA sequencing data from mouse gastrocnemius muscle and compared it with transcriptomic data from healthy young and older adults obtained through the National Institute on Aging's GESTALT study. The results revealed substantial differences between the two species. Despite both mice and humans experiencing age-related muscle decline, fewer than 5% of significantly altered biological pathways were shared between them. Many of the genetic programs that changed with aging in mice showed little resemblance to those observed in human skeletal muscle.

Why do some people appear to age faster than others, even when they are the same age? Researchers increasingly believe that chronological age tells only part of the story. Biological age attempts to capture how well the body's systems are functioning and may provide a more meaningful picture of overall health. A research paper on this topic was published in Volume 18 of Aging titled “Blood biochemical and gut microbiotic neural network models forecasting human biological age.” In the study, Russian researchers explored whether information from routine blood tests and the gut microbiome could be used to estimate biological age.

BUFFALO, NY — June 5, 2026 — A new #review was #published in Volume 18 of Aging on May 15, 2026, titled “Blue period – features of senescence 30 years after beta-galactosidase.” The review was led by first author Chisaka Kuehnemann and corresponding author Christopher D. Wiley from Tufts University. Cellular senescence has emerged as one of the most important biological processes linked to aging and age-related disease. Senescent cells stop dividing in response to stress or damage, yet they remain metabolically active and release a variety of signaling molecules that can influence surrounding tissues. Over the past three decades, evidence has increasingly shown that the accumulation of these cells contributes to chronic inflammation, tissue dysfunction, and many degenerative conditions associated with aging. In this review, the authors examine how the field has evolved since the landmark discovery of senescence-associated beta-galactosidase (SA-β-gal) in 1995. That finding provided one of the first practical methods for identifying senescent cells and helped establish that these cells accumulate in aging tissues. Since then, researchers have identified numerous additional characteristics of senescence and developed new approaches to study their role in health and disease. The review highlights several major features now recognized as hallmarks of senescent cells. These include stable proliferative arrest, increased lysosomal activity, secretion of inflammatory and signaling molecules collectively known as the senescence-associated secretory phenotype (SASP), mitochondrial dysfunction, alterations in nuclear architecture, accumulation of metals and lipofuscin, and enhanced survival despite exposure to cellular stress.

BUFFALO, NY — June 3, 2026 — A new #research paper was #published in Volume 18 of Aging-US on May 15, 2026, titled “Extracellular vesicles released by senescent myoblasts affect recipient cells via miRNA-target interactions.” The study was led by first author Michael Kamal from the Department of Kinesiology at McMaster University and corresponding author Gianni Parise from the same university. As people age, skeletal muscle gradually loses strength, size, and regenerative capacity. Scientists have increasingly linked these changes to cellular senescence—a state in which damaged cells permanently stop dividing but remain metabolically active. These senescent cells release a complex mixture of signaling molecules known as the senescence-associated secretory phenotype (SASP), which can influence neighboring cells and contribute to tissue dysfunction. In this study, the researchers investigated whether extracellular vesicles (EVs)—tiny membrane-bound particles released by cells—play a role in this process. Specifically, they examined EVs released by senescent muscle precursor cells, known as myoblasts, and analyzed the microRNAs (miRNAs) carried within these vesicles. The team found that senescent myoblasts released factors that impaired normal muscle cell development. When healthy muscle cells were exposed to signals from senescent cells, the resulting muscle fibers became significantly smaller and displayed increased expression of genes associated with cellular stress and senescence. Further analysis revealed that EVs released by senescent myoblasts carried a distinct set of miRNAs. The researchers identified 22 significantly altered miRNAs, including several previously linked to cellular senescence, such as miR-34a, miR-34b, miR-34c, and miR-22. The study also identified miR-301a-3p as a potentially novel senescence-associated miRNA.

BUFFALO, NY — May 27, 2026 — A new #research paper was #published in Volume 18 of Aging-US on May 8, 2026, titled “The mediating role of DNA methylation clocks in associations of race, ethnicity, education, income, and occupation with mortality: findings from NHANES 1999-2002.” The study was led by first and corresponding author Hanyang Shen from the Department of Epidemiology and Population Health at Stanford University. In this study, the authors investigated whether DNA methylation aging biomarkers—often called epigenetic aging clocks—may help explain how social inequalities become biologically embedded and contribute to differences in mortality risk. Social factors such as race, ethnicity, educational attainment, household income, and occupation have long been associated with disparities in health outcomes and life expectancy. However, the biological mechanisms linking these social exposures to long-term disease risk and mortality remain incompletely understood. Using nationally representative data from 2,402 adults in the U.S. National Health and Nutrition Examination Survey (NHANES) 1999–2002 linked to mortality follow-up data through 2019, the researchers examined thirteen different DNA methylation biomarkers alongside traditional clinical and behavioral risk factors. The study evaluated whether these epigenetic aging measures mediated associations between social stratification factors and all-cause mortality. The findings showed that several DNA methylation clocks significantly mediated the relationship between social disadvantage and mortality risk. Among all biomarkers examined, GrimAge2 consistently demonstrated the strongest mediation effects, accounting for up to 52% of mortality disparities in some occupational comparisons. DunedinPoAm, a pace-of-aging biomarker, also demonstrated substantial mediation effects across multiple socioeconomic categories. Importantly, the mediation effects observed for several DNA methylation biomarkers frequently exceeded those of traditional clinical risk factors measured in the study, including C-reactive protein and cholesterol-related markers. The results suggest that epigenetic aging measures may capture the cumulative biological effects of multiple social, environmental, behavioral, and physiological stressors simultaneously. “Among all the 13 DNA methylation biomarkers available in NHANES, GrimAge2 consistently exhibited the strongest positive mediation capturing the social disparities on mortality up to 52% (95%CI: 26%-128%), followed by the DunedinPoAm.” Full press release - https://aging-us.net/2026/05/27/dna-methylation-clocks-may-help-explain-how-social-inequality-influences-mortality/ DOI - https://doi.org/10.18632/aging.206377 Corresponding author - Hanyang Shen - hyshen@stanford.edu Abstract video - https://www.youtube.com/watch?v=XObIyirTJok Sign up for free Altmetric alerts about this article - https://aging.altmetric.com/details/email_updates?id=10.18632%2Faging.206377 Keywords - aging, race and ethnicity, social position, epigenetic aging, mediation analysis, mortality disparities To learn more about the journal, please visit https://www.Aging-US.com​​ and connect with us on social media at: Bluesky - https://bsky.app/profile/aging-us.bsky.social ResearchGate - https://www.researchgate.net/journal/Aging-1945-4589 X - https://twitter.com/AgingJrnl Facebook - https://www.facebook.com/AgingUS/ Instagram - https://www.instagram.com/agingjrnl/ LinkedIn - https://www.linkedin.com/company/aging/ Reddit - https://www.reddit.com/user/AgingUS/ Pinterest - https://www.pinterest.com/AgingUS/ YouTube - https://www.youtube.com/@Aging-US Spotify - https://open.spotify.com/show/1X4HQQgegjReaf6Mozn6Mc MEDIA@IMPACTJOURNALS.COM

BUFFALO, NY — May 20, 2026 — A new #editorial was #published in Volume 18 of Aging-US on May 18, 2026, titled “Public health in the age of longevity interventions: from prevention to system-wide resilience.” The editorial was authored by Jochen Mierau from the University of Groningen and Aging-US Editor-in-Chief Marco Demaria from the University of Groningen and European Research Institute for the Biology of Ageing (ERIBA). In this editorial, the authors examine how modern public health systems may need to evolve as aging populations increasingly face chronic disease, frailty, multimorbidity, and progressive loss of function rather than the acute infectious diseases that shaped 20th-century medicine. The authors argue that many of the greatest gains in human lifespan historically came not from advanced medical technologies, but from broad public health interventions such as sanitation, vaccination, improved nutrition, occupational safety, safer housing, and access to education. While these measures remain essential, they suggest that modern aging societies now face a different challenge: extending healthspan alongside lifespan. The editorial highlights how today's health risks accumulate gradually across the life course through environmental, metabolic, social, and behavioral exposures. Ultra-processed foods, pollution, tobacco, alcohol, sedentary lifestyles, climate-related stressors, and social isolation are described as contributors to accelerated biological aging and increased vulnerability to chronic disease. The authors emphasize that these interconnected exposures cannot be fully addressed through disease-specific treatment alone. “Rather than representing separate or competing domains, these approaches should be viewed as complementary components of a unified strategy to improve population health across aging societies.” A major focus of the article is the growing scientific interest in longevity-directed interventions that target core biological mechanisms of aging. The authors discuss pathways including cellular senescence, chronic inflammation, metabolic dysfunction, and impaired proteostasis, noting that interventions directed at these processes may help delay or modify multiple age-related diseases simultaneously rather than treating each condition individually after it emerges. Importantly, the editorial emphasizes that longevity interventions should not replace either public health or conventional clinical medicine. Instead, the authors propose a coordinated framework operating across the life course. In this model, public health strategies reduce baseline risk and environmental damage, clinical medicine treats established disease, and longevity-focused therapies may help slow biological decline before major pathology becomes clinically apparent. Figure 1 of the paper (page 2) illustrates this proposed multi-layered framework integrating public health, longevity interventions, and disease-specific care across different stages of life.

BUFFALO, NY — May 19, 2026 — A new #research paper was #published in Volume 18 of Aging-US on May 5, 2026, titled “Methylene blue protects hair follicle stem cells from oxidative and metabolic stress to enhance hair regeneration.” The study was led by first author Kavitha Sadashivaiah and corresponding author Kan Cao from the Department of Cell Biology and Molecular Genetics at the University of Maryland, College Park. In this study, the authors investigated how methylene blue (MB), a long-established mitochondrial-targeted antioxidant, affects human hair follicle stem cells (HFSCs) under conditions of oxidative and metabolic stress. Hair follicle stem cells are essential for maintaining hair growth and regeneration, but aging, ultraviolet radiation, oxidative stress, and metabolic dysfunction can impair their regenerative capacity and contribute to hair thinning and scalp aging. Using cultured human HFSCs, the researchers found that methylene blue significantly enhanced stem cell proliferation and viability while reducing intracellular reactive oxygen species (ROS). Importantly, MB also increased activation of β-catenin signaling, a central pathway involved in hair follicle regeneration, stem cell maintenance, and wound repair. Functional scratch-assay experiments further demonstrated that MB accelerated wound closure and regenerative activity in HFSC cultures. The study also explored how methylene blue interacts with other compounds commonly associated with scalp or hair health. While antioxidant vitamins A and C improved oxidative stress scavenging, they unexpectedly reduced MB-induced β-catenin activation when used in combination. In contrast, minoxidil—the widely used hair growth stimulant—worked synergistically with MB to further enhance β-catenin signaling and improve HFSC viability. “Overall, these findings identify methylene blue as a multifunctional therapeutic candidate that reduces oxidative and metabolic stress while supporting HFSC–mediated hair regeneration.” Another major focus of the paper involved glucagon-like peptide-1 receptor agonists (GLP-1 RAs), medications increasingly used for diabetes and weight management. Recent clinical observations have suggested that some patients receiving GLP-1 RA therapy may experience hair thinning or hair loss. The authors demonstrated that increasing GLP-1 RA concentrations caused dose-dependent reductions in HFSC viability in vitro. However, pretreatment with methylene blue substantially protected the stem cells from GLP-1 RA–associated metabolic stress and premature cell death. Beyond stem cell protection, the paper discusses methylene blue's broader potential role in scalp health. Because MB absorbs ultraviolet radiation and has previously demonstrated protective effects against UV-induced DNA damage in skin cells, the authors propose that it may help shield the scalp microenvironment from oxidative injury while supporting regenerative signaling pathways important for hair maintenance. The study also highlights MB's possible antimicrobial properties and its potential influence on scalp microbiome balance. Importantly, the authors emphasize that the findings are based on in vitro cellular models and that further in vivo studies will be necessary before clinical applications can be established. Additional research will be required to define appropriate dosing, pharmacokinetics, long-term safety, and therapeutic efficacy in living systems. Overall, this study identifies methylene blue as a potentially multifunctional therapeutic candidate for supporting hair follicle stem cell health under conditions of oxidative, metabolic, and pharmacologic stress. By combining antioxidant activity with activation of regenerative β-catenin signaling, MB may represent a promising future strategy for protecting scalp health, enhancing hair regeneration, and improving the resilience of aging hair follicle stem cells.

Each month, we will highlight a paper published in Aging-US chosen as the “Editors' Choice.” These selections are handpicked by our editors and accompanied by a brief summary, showcasing research with significant impact and novel insights in aging and age-related diseases. __________ In the research paper, titled “Association of epigenetic age acceleration with MRI biomarkers of aging and Alzheimer's disease neurodegeneration,” researchers investigated whether epigenetic clocks of biological aging are associated with MRI markers of brain aging and Alzheimer's disease-related neurodegeneration in 1,196 older women. While none of the five epigenetic clocks examined were linked to accelerated overall brain aging, one measure (AgeAccelGrim2) was associated with MRI patterns related to neurodegeneration. The findings suggest this relationship was largely driven by DNA methylation markers linked to smoking history and changes in frontal and temporal brain regions rather than areas typically affected early in Alzheimer's disease. Overall, the study indicates that epigenetic aging and brain aging may reflect different aspects of the aging process, while highlighting the potential role of smoking-related biological aging in increasing dementia risk.

BUFFALO, NY — May 15, 2026 — A new #review was #published in Volume 18 of Aging-US on May 4, 2026, titled “Cellular senescence: from pathogenic mechanisms to precision anti-aging interventions.” The study was led by first author Jian Deng and corresponding author Dong Yang from the Department of Targeting Therapy and Immunology, Cancer Center, West China Hospital, Sichuan University, Chengdu, Sichuan, China. In this comprehensive review, the authors examine how cellular senescence contributes to aging and age-related disease across multiple organ systems, while also highlighting the emerging complexity and functional diversity of senescent cell populations. Traditionally, senescent cells have been viewed primarily as harmful byproducts of aging, characterized by irreversible cell-cycle arrest and chronic inflammatory signaling. However, growing evidence suggests that some senescent cells also play beneficial physiological roles in tissue repair, embryonic development, and maintenance of tissue homeostasis. The review outlines how senescence develops in major tissues including the liver, lungs, kidneys, heart, adipose tissue, brain, and skin. Across these organs, aging-related cellular dysfunction is driven by a combination of oxidative stress, mitochondrial dysfunction, DNA damage, chronic inflammation, metabolic stress, telomere shortening, and environmental insults such as ultraviolet radiation and pollution. The authors describe how senescent cells accumulate in highly specialized cell populations—including hepatocytes, endothelial cells, fibroblasts, macrophages, astrocytes, and epithelial cells—where they can disrupt normal tissue architecture and promote chronic disease progression. Importantly, the article emphasizes that senescent cells are highly heterogeneous and should not be treated as a uniform population. Depending on the tissue context and biological environment, senescent cells may exert either protective or harmful effects. For example, certain senescent cells may help limit fibrosis or support wound healing, whereas others drive chronic inflammation, metabolic dysfunction, tissue degeneration, and cancer progression. This growing recognition of functional heterogeneity has prompted a major shift in anti-aging research away from indiscriminate elimination of senescent cells toward more selective and precision-based therapeutic strategies. “Based on these insights, this review summarizes the induction mechanisms of cellular senescence and the subsequent evolution of their functional phenotypes across diverse tissues.” Full press release - https://www.aging-us.com/news-room/precision-anti-aging-strategies-aim-to-target-harmful-senescent-cells-while-preserving-beneficial-ones Paper DOI - https://doi.org/10.18632/aging.206375 Corresponding author - Dong Yang – yangdong@wchscu.cn Abstract video - https://www.youtube.com/watch?v=HkJRwF8mp4A Keywords - cellular senescence, aging mechanisms, functional heterogeneity, precision anti-aging To learn more about the journal, please visit www.Aging-US.com​​ and connect with us on social media at: Bluesky - bsky.app/profile/aging-us.bsky.social ResearchGate - www.researchgate.net/journal/Aging-1945-4589 X - twitter.com/AgingJrnl Facebook - www.facebook.com/AgingUS/ Instagram - www.instagram.com/agingjrnl/ LinkedIn - www.linkedin.com/company/aging/ Reddit - www.reddit.com/user/AgingUS/ Pinterest - www.pinterest.com/AgingUS/ YouTube - www.youtube.com/@Aging-US Spotify - open.spotify.com/show/1X4HQQgegjReaf6Mozn6Mc MEDIA@IMPACTJOURNALS.COM

Efforts to improve metabolic health through dietary interventions often come with trade-offs. Some approaches that reduce obesity or extend lifespan in laboratory models can also negatively affect other tissues, including bone. One example is sulfur amino acid restriction (SAAR), a diet low in methionine and lacking cysteine that has repeatedly shown strong anti-obesity effects in animal studies. However, despite these promising metabolic benefits, SAAR has also been associated with reduced bone mineral density, weaker bones, and increased marrow fat accumulation. This has led researchers to ask whether the metabolic benefits of SAAR can be separated from its harmful skeletal effects. A new research paper was published in Volume 18 of Aging-US, titled “D, L-Buthionine-(S, R)-sulfoximine recapitulates the anti-obesity effects of sulfur amino acid restriction without the associated deleterious effects on bone in male mice.” The researchers investigated whether those metabolic benefits could be achieved without the same harmful effects on bone. The study was led by first author Naidu B. Ommi and corresponding author Sailendra N. Nichenametla from the Orentreich Foundation for the Advancement of Science Inc., in collaboration with Dwight A. L. Mattocks from the same institution and Mark C. Horowitz from the Yale University School of Medicine.

BUFFALO, NY — May 12, 2026 — A new #research paper was #published in Volume 18 of Aging-US on May 4, 2026, titled “Host immunosenescence compromises Mycobacterium tuberculosis clearance.” The study was led by first author Falak Pahwa and corresponding author Ranjan Kumar Nanda from the International Centre for Genetic Engineering and Biotechnology (ICGEB), New Delhi, India. In this study, the authors investigated how aging alters immune responses during tuberculosis infection and treatment. Tuberculosis remains one of the world's deadliest infectious diseases, and older adults are particularly vulnerable due to immunosenescence, the gradual decline of immune function that occurs with aging. Despite the growing burden of tuberculosis in aging populations worldwide, most experimental models continue to rely on young adult animals that do not accurately reflect immune aging. Using multiple age groups of C57BL/6 mice, the researchers examined how aging affects the body's ability to control Mycobacterium tuberculosis during treatment with rifampicin and isoniazid (RIF-INH), two cornerstone anti-tuberculosis drugs. While young and older mice initially showed similar bacterial burden following infection, older mice demonstrated significantly delayed bacterial clearance in the lungs during the early phase of treatment. Importantly, the study identified several age-associated immune abnormalities linked to impaired bacterial clearance. Older mice exhibited chronic inflammatory signaling, altered T cell responses, accumulation of T-follicular cytotoxic (TFC)-like cells, and evidence of mitochondrial dysfunction within immune cells. Proteomic analysis of splenic CD4+CD44+ T cells further revealed dysregulation of mitochondrial proteins involved in cellular metabolism and immune function. “Collectively, these findings suggest that age-associated immune alterations may disrupt immunometabolic pathways, thereby contributing to the delayed Mtb clearance.” The researchers also observed that older mice maintained elevated inflammatory cytokine levels and developed persistent lung inflammation even after treatment had begun. At the same time, key protective immune responses appeared functionally impaired, suggesting that aging may disrupt the balance between inflammation and effective pathogen control. Together, these findings suggest that age-related immunometabolic dysfunction may play a major role in the reduced treatment response observed in older hosts. Notably, the study found that delayed bacterial clearance in older mice did not appear to result primarily from liver toxicity or impaired drug metabolism. Instead, the evidence suggested that age-related immune dysfunction itself was the dominant factor limiting effective bacterial elimination during therapy. The paper further highlights the emerging importance of mitochondrial health in immune cell function during aging. The authors propose that targeting age-associated immunometabolic defects and mitochondrial dysfunction may represent a promising strategy for improving tuberculosis treatment outcomes in elderly populations. Overall, this study provides new insight into why older adults experience poorer tuberculosis outcomes despite receiving standard therapy. As global populations continue to age, understanding how immunosenescence alters infectious disease responses may become increasingly important for the development of more effective treatment strategies and age-adapted therapeutic interventions.

BUFFALO, NY — May 7, 2026 — A new #research paper was #published in Volume 18 of Aging-US on April 24, 2026, titled “The BHARAT study: a multi-modal, multi-omics investigation of aging signatures in the Indian population.” The study was led by first author Suramya Asthana and corresponding author Deepak Kumar Saini from the Indian Institute of Science (IISc). The authors introduce the BHARAT Study (Biomarkers of Healthy Aging, Resilience, Adversity, and Transitions), India's first large-scale, discovery-driven multi-omics cohort focused on understanding biological aging in the Indian population. The initiative was developed to address a major gap in aging research, as most existing biological age models and aging datasets have been derived primarily from Western populations. The BHARAT study is a multi-center, cross-sectional observational cohort that integrates clinical, molecular, lifestyle, and environmental data from participants across diverse demographic groups in India. The initiative aims to enroll healthy volunteers spanning multiple age groups, with balanced rural-urban and sex representation. Biological samples—including blood, urine, stool, cheek swabs, and hair—will undergo extensive multi-omics profiling, including epigenomics, proteomics, metabolomics, lipidomics, metagenomics, and immune phenotyping. “By generating interoperable, high-resolution data suited for mechanistic modelling and machine learning, BHARAT contributes a resource of global relevance that would be capable of refining universal models of aging biology while revealing novel, population-specific pathways that inform prevention and intervention strategies.” The initiative uses a hub-and-spoke framework centered at the Indian Institute of Science, which serves as the central hub for biobanking, multi-omics analysis, computational integration, and AI-driven modeling. Clinical and community partners across India contribute participant recruitment, clinical assessments, and biological sampling, enabling the study to capture the country's extraordinary genetic, environmental, dietary, and socioeconomic diversity. A major focus of the study is the development of population-specific biological aging signatures and predictive models tailored to Indian populations. Researchers aim to identify biomarkers associated with resilience, frailty, and age-related decline while also recalibrating biological clocks that may not accurately reflect aging trajectories in non-Western populations. The study further seeks to establish standardized reference datasets and create scalable infrastructure for future longitudinal aging research in India. Importantly, the BHARAT study combines untargeted discovery-based omics technologies with advanced artificial intelligence and machine learning approaches. By integrating molecular data with clinical and lifestyle information, the initiative aims to improve understanding of how biological aging is shaped by genetics, environment, nutrition, infection burden, and social determinants of health. Overall, this study establishes a comprehensive framework for aging research in one of the world's most diverse populations. By generating large-scale, population-specific biological datasets, the BHARAT initiative may help advance precision aging research, improve risk prediction models, and support the development of more personalized approaches to healthy aging and disease prevention.

BUFFALO, NY — May 5, 2026 — A new #research paper was #published in Volume 18 of Aging-US on April 13, 2026, titled “Cross species activity of TERT human telomerase component.” The study was led by co–first authors Raúl Sánchez-Vázquez and Paula Martínez, with María A. Blasco serving as corresponding author, from the Spanish National Cancer Centre (CNIO), Madrid, Spain. In this study, the researchers explored a key question in aging and regenerative medicine: can the human telomerase protein function effectively in other species commonly used in preclinical research? Telomerase plays a central role in maintaining chromosome integrity by preventing telomere shortening—a process closely linked to cellular aging and disease. To investigate this, the team introduced the human telomerase catalytic subunit (TERT) into primary lung fibroblasts from several mammalian species, including monkey, pig, rabbit, rat, dog, and mouse. They then assessed both biochemical activity and the ability of telomerase to extend telomeres over time. The results revealed a clear distinction between biochemical compatibility and true biological function. In vitro, human TERT was able to form active complexes with telomerase RNA from several species, including monkey, pig, rabbit, and rat. However, this activity did not always translate into effective telomere maintenance in living cells. Notably, only human and non-human primate cells showed progressive telomere lengthening over time. In contrast, other species—even those showing initial enzymatic activity—failed to sustain telomere extension during long-term culture. In some cases, telomeres continued to shorten, suggesting that functional integration of telomerase depends on additional species-specific factors. The study also uncovered important limitations in commonly used animal models. Mouse and canine cells did not support human TERT activity, and in some cases, expression of the human enzyme led to reduced cell viability and signs of cellular stress. “These results reveal that only non-human primate cells support full functional activity of the human telomerase protein in a cellular context, underscoring their suitability as preclinical models for telomerase-based therapeutic strategies.” Importantly, the findings highlight that successful telomerase activity in a test tube does not necessarily reflect what happens inside a living cell. The recruitment, regulation, and function of telomerase depend on a complex network of interacting proteins and cellular processes, many of which differ across species. Overall, this study provides important insight into the challenges of translating telomerase-based therapies from preclinical models to humans. By identifying non-human primates as the most compatible system, the work offers a clearer path forward for developing therapies aimed at treating telomere-related diseases and age-associated conditions.

BUFFALO, NY — April 29, 2026 — A new #research paper was #published in Volume 18 of Aging-US on April 10, 2026, titled “Stage-dependent transcriptomic changes in human dermal fibroblast senescence model.” The study was led by first author Michiko Kudo from the University of Tokyo and DHC Corporation Laboratories and corresponding author Shuichi Asakawa from the University of Tokyo. In this work, the researchers took a closer look at how gene expression changes as cells age, focusing on human dermal fibroblasts—a widely used model for studying aging in skin and connective tissues. While cellular senescence is known to play a central role in aging, the timing and progression of molecular changes during this process have remained difficult to define. To explore this, the team developed a stepwise model of replicative senescence, categorizing cells into three stages—young, middle, and old—based on their cumulative number of divisions. This approach allowed them to capture the gradual nature of aging, rather than relying on acute stress models that may overlook early-stage transitions. One of the more interesting findings was that the “middle” stage—often overlooked—is not just a simple midpoint, but a biologically active transition phase. Although gene expression profiles in young and middle cells appeared similar at first glance, a closer look showed that important molecular changes had already begun during this phase. In particular, genes involved in immune and inflammatory responses were activated early, even before cells reached full senescence. This suggests that aging-related inflammation may begin much earlier than previously appreciated, gradually intensifying as cells progress toward the late stage. At the same time, genes responsible for maintaining basic cellular functions—such as protein synthesis, cell structure, and adhesion—showed a progressive decline as aging advanced. Together, these changes suggest a shift in cellular priorities, where stress and inflammatory signals increase while maintenance and repair functions gradually decline. To better understand these patterns, the researchers combined transcriptomic analysis with network and matrix factorization approaches. These methods revealed distinct gene expression programs associated with different stages of aging, including early immune activation, mid-stage extracellular remodeling, and late-stage functional decline. “These findings suggest that immune–inflammatory responses are engaged from early senescence, whereas cell adhesion and maintenance pathways decline progressively.” Importantly, the results point to the middle stage of senescence as a potential window for intervention. Unlike fully senescent cells, which exhibit more stable and potentially irreversible changes, cells in this transitional phase may retain some degree of plasticity, making them more responsive to therapeutic strategies. Overall, this study offers a clearer picture of how aging unfolds at the molecular level. By identifying stage-specific changes in gene expression, the authors provide new insight into the early drivers of cellular senescence and highlight potential targets for delaying or modifying age-related decline.

Aging has long been linked to a range of biological processes, including cellular senescence, epigenetic changes, and chronic tissue remodeling. Yet, these explanations often describe what happens during aging rather than why certain age-related diseases, such as fibrosis, continue to progress over time. In conditions like idiopathic pulmonary fibrosis (IPF), a key question remains: what drives the persistent activation of cells that should normally return to a resting state after injury? Increasing attention has turned to the interaction between cellular signaling pathways and epigenetic regulation as a potential explanation. Understanding how these processes work together to control gene expression and cell behavior is becoming an important focus in uncovering the mechanisms behind age-related disease. A new research paper was published in Volume 18 of Aging-US, titled “P38 MAPK is involved in epigenetic regulation of fibrotic genes in replication induced senescence in lung fibroblasts.” The study was led by first author Shan Zhu and corresponding author Yan Y.

BUFFALO, NY — April 27, 2026 — A new #hypothesis paper was #published in Volume 18 of Aging-US on April 8, 2026, titled “From Hydra to rotifer and beyond: implications for human aging and delayed senescence.” The study was led by first and corresponding author Michael Bordonaro from the Geisinger College of Health Sciences. In this work, the author explores a bold and testable hypothesis centered on two very different invertebrate models of aging: the freshwater cnidarian Hydra and the rotifer Brachionus manjavacas. Hydra are well known for their remarkable ability to maintain tissue integrity over time through continuous stem cell renewal, effectively avoiding many of the hallmarks of aging under laboratory conditions. In contrast, rotifers represent the opposite end of the biological spectrum, with short lifespans, fixed somatic cell numbers, and a predictable pattern of age-related decline. Building on these contrasts, the paper proposes that introducing Hydra-like gene expression patterns into rotifers could delay senescence and extend healthspan. The hypothesis focuses in particular on conserved molecular pathways, including the transcription factor FoxO, which plays a central role in maintaining stem cell function and cellular resilience. Rather than attempting to recreate full stem cell renewal in rotifers—an organism with a fixed adult cell number—the proposed strategy emphasizes improving cellular maintenance, stress resistance, and proteostasis within existing cells. The paper outlines an iterative experimental framework, beginning with targeted genetic manipulation in rotifers and extending to more complex organisms such as Daphnia and mouse models. This stepwise approach is designed to identify which elements of the Hydra genetic program are truly responsible for its resistance to aging, while also allowing researchers to monitor potential trade-offs, including increased risk of uncontrolled cell growth. “We hypothesize that delayed senescence at the organismal level is possible through recapitulation of Hydra-like patterns of gene expression in rotifers, and that data obtained may help generate hypotheses for somatic interventions and prioritize pathways for mammalian validation in future studies.” Importantly, the author emphasizes that complete elimination of aging is unlikely in complex organisms due to evolutionary and biological constraints. Instead, the goal is more realistic: extending healthspan and delaying the onset of age-related decline. The paper also highlights the importance of balancing potential benefits with risks, particularly the possibility that enhancing cellular renewal pathways could increase susceptibility to neoplasia. Overall, this study presents a conceptual and experimental roadmap for translating insights from simple organisms into strategies that may eventually inform human aging research. By bridging the gap between negligible senescence and rapid aging models, the work provides a fresh perspective on how conserved biological mechanisms might be harnessed to improve health across the lifespan.

BUFFALO, NY — April 23, 2026 — A new #research paper was #published in Volume 18 of Aging-US on April 7, 2026, titled “Association of epigenetic age acceleration with MRI biomarkers of aging and Alzheimer's disease neurodegeneration.” The study was led by first and corresponding author Linda K. McEvoy from the Kaiser Permanente Washington Health Research Institute, in collaboration with a multidisciplinary team of researchers across leading institutions in the United States and Europe. In this study, the researchers examined whether epigenetic measures of biological aging are associated with structural brain changes linked to aging and Alzheimer's disease. Using data from 1,196 older women enrolled in the Women's Health Initiative Memory Study, they analyzed five widely used epigenetic clocks and compared them with MRI-derived measures obtained approximately eight years later. The findings revealed a clear distinction between different aspects of aging. None of the epigenetic clocks were associated with accelerated brain aging as measured by the SPARE-BA index, a composite MRI marker of brain age. However, one specific clock—AgeAccelGrim2—was significantly associated with the Alzheimer's Disease Pattern Similarity Score (AD-PS), a validated imaging biomarker linked to increased risk of dementia. Further analyses suggested that this association was largely driven by epigenetic signatures related to smoking exposure. In particular, a DNA methylation marker reflecting cumulative smoking history was linked to reduced frontal and temporal lobe volumes—regions commonly affected in age-related neurodegeneration. Notably, no significant associations were observed with hippocampal or entorhinal cortex volumes, areas more directly implicated in early Alzheimer's pathology. “Taken together with prior findings, these results suggest that measures of epigenetic and brain age acceleration capture different aspects of biological aging, and that AgeAccelGrim2 is predictive of neurodegenerative changes associated with smoking that increase risk of dementia.” The study highlights the complexity of biological aging and underscores that not all aging biomarkers reflect the same underlying processes. While epigenetic clocks are increasingly used to estimate biological age, their relationship with brain structure appears to depend on the specific pathways they capture—particularly those influenced by environmental exposures such as smoking. Overall, these findings provide important insight into how molecular measures of aging relate to neuroimaging markers of brain health. By distinguishing between general brain aging and disease-related neurodegeneration, this work helps refine the use of epigenetic biomarkers in aging research and may support future efforts to identify individuals at risk for cognitive decline.

BUFFALO, NY — April 21, 2026 — A new meeting report was published in Volume 18 of Aging-US on April 6, 2026, titled “Toward actionable interventions in human aging (12th ARDD meeting, 2025).” The report was led by corresponding authors Aleksandr Dekan and Daniela Bakula from the University of Copenhagen, Denmark, in collaboration with an international group of researchers spanning academia, industry, and biotechnology. Bringing together experts from across the global aging research community, the 12th ARDD meeting focused on one central goal: moving beyond descriptive studies of aging toward interventions that can actively improve human healthspan. The discussions reflected a clear shift in the field—from understanding the hallmarks of aging to identifying the molecular mechanisms that can be targeted to modify them. Key presentations explored whether biological age can be reversed, highlighting the epigenome as a central regulator of cellular identity. Emerging evidence suggests that partial cellular reprogramming may restore youthful function, while systemic effects observed in preclinical models point to the possibility of organ-wide or even whole-body rejuvenation. The meeting also emphasized the importance of maintaining genomic integrity, with accumulating DNA damage linked to widespread transcriptional stress and age-associated functional decline. At the same time, chronic inflammation, metabolic dysfunction, and cellular senescence were consistently identified as major drivers of aging, reinforcing the need for integrated, multi-targeted therapeutic strategies. Advances in biomarker development were another major focus. Researchers presented new generations of biological aging clocks—ranging from organ-specific proteomic signatures to single-cell and imaging-based approaches—capable of predicting disease risk and monitoring intervention outcomes with increasing precision. In parallel, the integration of artificial intelligence into drug discovery is accelerating the development of novel therapeutics. From generative AI-designed proteins to platform-based identification of new drug targets, these approaches are helping bridge the gap between basic research and clinical application. “This focus is predicated on the hypothesis that aging is not solely a result of stochastic damage accumulation but may be a tractable, modifiable, and potentially reversible biological process amenable to intervention.” Beyond laboratory science, the meeting highlighted the growing importance of translational strategies, regulatory pathways, and investment models in bringing anti-aging therapies to market. A consensus emerged around a “disease-first” approach, in which targeting specific age-related conditions may provide a practical pathway for validating interventions that also influence underlying aging biology. Overall, the ARDD 2025 meeting underscored a major turning point in the field. Aging research is no longer confined to observation—it is increasingly positioned to deliver actionable interventions that could reshape how age-related diseases are prevented and treated.

BUFFALO, NY — April 17, 2026 — A new #research paper was #published in Volume 18 of Aging-US on April 3, 2026, titled “Modeling premature aging in yeast via the expression of Progerin.” The study was led by first author Zachery R. Belak from the University of Saskatchewan, and corresponding author Troy A.A. Harkness from the University of Saskatchewan and the University of Alberta. The team developed a yeast-based model to study premature aging by expressing Progerin, the toxic protein responsible for Hutchinson–Gilford Progeria Syndrome. Using genetically engineered yeast cells, they compared the effects of Progerin with its normal counterpart, Lamin A, to better understand how protein accumulation impacts cellular aging. Their findings show that Progerin expression leads to slower cell growth, increased genome instability, and a significant reduction in chronological lifespan. In contrast, Lamin A did not produce the same harmful effects, highlighting the specific role of Progerin in driving premature aging phenotypes. The study also demonstrates that Progerin accumulates in aging mother cells and remains more stable than Lamin A, suggesting a mechanism by which damaged or toxic proteins are retained during the aging process. These observations mirror what has been reported in human cells, reinforcing the relevance of this model system. “Taken together, expression of Progerin in yeast cells mimics what is observed in human cells, establishing yeast as a powerful model to discover genetic mechanisms driving premature and normal aging.” Overall, the researchers present a practical and efficient model for studying the biological mechanisms underlying premature aging. Their work provides a valuable platform for testing new strategies aimed at reducing toxic protein accumulation and improving cellular health during aging.

BUFFALO, NY — April 15, 2026 — A new #research paper was #published in Volume 18 of Aging-US on March 30, 2026, titled “A manually curated gene–phenotype catalogue for progeroid syndromes and premature aging.” The study was led by Nuša Likar and Tanja Kunej from the University of Ljubljana, Slovenia. The researchers developed a comprehensive, manually curated catalogue integrating data from 84 scientific publications and the OMIM database. The resulting resource systematically organizes genetic and clinical information on progeroid syndromes, linking 144 genes to 56 syndromes and 160 distinct clinical entities, making it one of the most extensive datasets in this field to date. Using genome–phenome association analysis and protein–protein interaction networks, the study reveals the complex genetic and phenotypic heterogeneity underlying premature aging disorders. The findings highlight strong enrichment in genome maintenance and DNA repair pathways, reinforcing their central role in aging biology. The catalogue also demonstrates how single genes, such as LMNA, can be associated with multiple syndromes, illustrating the pleiotropic nature of genetic variants in progeroid conditions and their broader relevance to human aging mechanisms. “Overall, this study provides a reference resource and framework to support future research into premature aging syndromes and their broader implications for understanding physiological aging.” Overall, the authors present a valuable framework for improving the classification, diagnosis, and study of rare premature aging disorders. Their work not only advances understanding of progeroid syndromes but also offers important insights into the biological processes that drive normal human aging.

We examined associations between circulating levels of theobromine intake, measured using serum metabolomics, and blood-based epigenetic markers of biological ageing in two European human population-based cohorts. Serum theobromine levels were significantly associated with reduced epigenetic age acceleration, as measured by GrimAge (p < 2e-7) and DNAmTL (p < 0.001) in 509 individuals from the TwinsUK cohort, and both signals replicated in 1,160 individuals from the KORA cohort (p = 7.2e-08 and p = 0.007, respectively). Sensitivity analyses including covariates of other cocoa and coffee metabolites suggest that the effect is specific to theobromine. Our findings indicate that the reported beneficial links between theobromine intake on health and ageing extend to the molecular epigenetic level in humans.
