Each month, we will highlight a paper published in Aging 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. __________ This month’s Editors’ Choice, “Investigating the efficacy and toxicity of partial in vivo reprogramming as a rejuvenation intervention,” examines the potential benefits and risks of partial cellular reprogramming as an approach to rejuvenation. Analyzing gene expression data from the liver, kidney, and spleen of aged mice, the researchers identified tissue-specific responses, including reduced age-related inflammation and improved metabolic pathway activity in the liver and kidney. However, findings in the spleen suggested increased cellular proliferation and potential genomic stress, highlighting important safety considerations. This study underscores the need for further research to better understand the long-term effects and safety of partial reprogramming as a potential aging intervention.

BUFFALO, NY — November 12, 2026 — A new #research paper was #published in Volume 18 of Aging on October 27, 2026, titled “Investigating the efficacy and toxicity of partial in vivo reprogramming as a rejuvenation intervention.” The study examines how partial cellular reprogramming, an experimental approach aimed at reversing certain age-related changes, affects different organs. Researchers found potentially beneficial molecular changes in the liver and kidneys of aged mice, alongside signals in the spleen that raise concerns about the intervention’s long-term safety. The paper’s first and corresponding author is Franziska Meiners, affiliated with the Institute for Biostatistics and Informatics in Medicine and Ageing Research at University Medical Center Rostock, Germany. Partial reprogramming has emerged as a potential rejuvenation strategy by temporarily activating proteins known as Yamanaka factors. These proteins can alter gene activity and may help restore some youthful cellular characteristics. However, concerns remain about possible adverse effects, including uncontrolled cell proliferation and genomic instability. To investigate these effects, the researchers reanalyzed previously published gene-expression data from the liver, kidneys and spleen of aged mice that had undergone seven months of partial reprogramming. They used the Adverse Outcome Pathway framework to examine molecular changes associated with potential benefits and risks. The analysis revealed different responses across the three organs. In the liver and kidneys, partial reprogramming was associated with reduced expression of inflammation-related genes and increased expression of genes involved in metabolic pathways that typically decline with age.

BUFFALO, NY — November 10, 2026 — A new #research perspective was #published in Volume 18 of Aging on October 20, 2026, titled “From hyperfunction to systemic amplification: reframing the logic of late-life rejuvenation.” The paper proposes a new framework for understanding why aging accelerates later in life and how future rejuvenation strategies could address this decline. Rather than focusing only on molecular damage accumulating within individual cells, the author suggests that communication between cells and organs plays a central role in amplifying age-related changes throughout the body. The research perspective was authored by Pierre-Edouard Sottas, who is affiliated with the xLongevity Center in Vevey, Switzerland. Aging is commonly understood as the gradual accumulation of cellular damage, including DNA alterations, mitochondrial dysfunction and changes in gene regulation. However, this explanation does not fully account for why functional decline and mortality risk often accelerate sharply in later life. Building on the hyperfunction theory developed by Mikhail Blagosklonny, the paper explores how biological processes that support growth, repair and survival earlier in life can become harmful when their activity persists or becomes excessive. Sottas introduces an integrative-first load–gain framework that distinguishes between two components of aging. The first, known as the damage load, represents molecular damage that gradually accumulates within cells. The second, systemic gain, describes how communication networks throughout the body can amplify the effects of that damage. According to the proposed framework, inflammatory signals, immune and hormonal changes, and extracellular vesicles can spread stress-related messages between cells and tissues. When these signals become persistent and self-reinforcing, they could contribute to the accelerated decline associated with advanced age. The perspective draws on research involving plasma exchange, extracellular vesicle-based interventions and cellular reprogramming to explore how changes in the body’s internal environment can influence aging-related processes across multiple tissues.

Two people can be the same chronological age and yet differ considerably in how quickly their bodies appear to be aging. Scientists have developed “epigenetic clocks” that use chemical changes to DNA to estimate aspects of biological aging. But whether an older biological age measured in blood also means that the brain is aging faster has remained unclear. A research paper published in Volume 18 of Aging titled “Association of epigenetic age acceleration with MRI biomarkers of aging and Alzheimer’s disease neurodegeneration,” investigated that question in 1,196 older women. The study was led by first and corresponding author Linda K. McEvoy of the Kaiser Permanente Washington Health Research Institute. The researchers compared five widely used epigenetic aging measures with structural MRI scans obtained an average of about eight years later. None of the five clocks was associated with a general measure of accelerated brain aging. One clock, however—GrimAge2—was associated with an MRI pattern linked to greater dementia risk. A closer look suggested that this relationship was largely connected to an epigenetic signature of smoking exposure and to lower volumes in the frontal and temporal regions of the brain, rather than to the hippocampus and entorhinal cortex, which are strongly implicated in early Alzheimer’s disease. The findings suggest that biological aging cannot necessarily be reduced to a single number. A blood-based aging measure may capture important health-related processes without directly reflecting how old the brain appears on MRI.

BUFFALO, NY — November 5, 2026 — A new #research paper was #published in Volume 18 of Aging on October 14, 2026, titled “Ferroptosis-related hub genes and immune infiltration characteristics in Duchenne muscular dystrophy: a molecular framework with implications for aging-related muscle degeneration.” The study identified three genes associated with ferroptosis, an iron-dependent form of cell death, and changes in immune-related signals in Duchenne muscular dystrophy (DMD). By analyzing human muscle gene-expression data and conducting experiments in mice, the researchers identified molecular characteristics that may also be relevant to age-related muscle degeneration. The findings offer new insights into potential connections between iron metabolism, inflammation and muscle health. The research was led by equal-contributing first authors Juanjuan Peng, affiliated with Nanjing University of Chinese Medicine, and Jing Hu, affiliated with Nanjing Jiangning Hospital of Chinese Medicine. Corresponding author Houxi Xu is affiliated with the Nanjing University of Chinese Medicine. Age-related muscle loss, known as sarcopenia, is a major contributor to frailty, disability and declining independence in older adults. Although its causes are complex, growing evidence suggests that iron accumulation, oxidative stress, inflammation and impaired muscle regeneration may contribute to progressive muscle deterioration. One emerging mechanism is ferroptosis, a form of regulated cell death caused by iron-dependent oxidative damage to cellular membranes. Researchers are increasingly investigating whether this process contributes to muscle degeneration and whether understanding its regulation could reveal new approaches to preserving muscle function. Duchenne muscular dystrophy, a genetic disorder that causes progressive muscle weakness, shares certain pathological features with aging-related muscle degeneration. These include oxidative stress, chronic inflammation and reduced regenerative capacity. Although DMD is distinct from normal aging, these similarities provide an opportunity to investigate potentially shared molecular pathways. To explore these connections, the researchers analyzed two publicly available human DMD datasets containing 33 muscle samples from patients with DMD and 12 healthy controls. They identified 35 ferroptosis-related genes showing altered expression, with three emerging as particularly important: HIF1A, CDKN1A and CD44.

BUFFALO, NY — November 3, 2026 — A new #review was #published in Volume 18 of Aging on October 9, 2026, titled “The polycentric aging framework: epigenetic regulation as a dominant lifespan-limiting center in human aging.” The review introduces the Polycentric Aging Framework (PAF), which proposes that aging results from several interacting biological processes rather than a single universal mechanism. Drawing on evidence from cellular reprogramming, DNA methylation, metabolic signaling and human intervention studies, the authors suggest that epigenetic regulation may be a dominant, but not exclusive, factor limiting human lifespan. The framework offers a new perspective on how different aging mechanisms interact and how targeted interventions might help preserve biological function. The review was authored by first and corresponding author Michał Bartoszewicz, an independent researcher based in Warsaw, Poland, and co-author and corresponding author Mariusz Niemczyk, affiliated with the Medical University of Warsaw. Aging involves interconnected changes, including genomic instability, mitochondrial dysfunction, cellular senescence, impaired protein maintenance and declining regenerative capacity. Although these processes contribute to age-related deterioration, their relative importance in determining lifespan remains uncertain. Understanding their interactions may help researchers identify strategies to extend healthspan, the period of life spent in good health. The Polycentric Aging Framework organizes these processes into partially independent but interacting biological centers. Each differs in its timing, reversibility, influence on other systems and potential to limit lifespan. The authors propose that targeting one mechanism may improve function, but another biological constraint could subsequently become limiting, suggesting that effective interventions may need to address several processes over time. The framework identifies three major constraint layers: epigenetic regulation, irreversible genetic and physical damage, and the accumulation of damaged proteins and organelles. These interact with telomere dynamics, mitochondrial metabolism, stem-cell function, cellular senescence and systemic signaling.

BUFFALO, NY — October 29, 2026 — A new #research paper was #published in Volume 18 of Aging on October 8, 2026, titled “Small extracellular vesicles as mediators of paracrine senescence in cellular models of aging.” The study found that small extracellular vesicles (sEVs) released by senescent cells can transmit signals that promote senescence in neighboring cells. Using human cellular models of aging, the researchers demonstrated that these membrane-enclosed particles could trigger cell-cycle arrest and DNA damage responses without activating the classical inflammatory pathways associated with senescence. The findings reveal another mechanism through which aging cells may influence their surroundings. The research was led by equal-contributing first authors Aina M. Llabrés-Mas, Antonio Merino-Navarro and Marta Menéndez-García, all affiliated with the Spanish National Research Council (CSIC), Madrid, Spain. Corresponding author Ana O’Loghlen is affiliated with the same institution. Cellular senescence is a process in which cells enter a stable state of growth arrest in response to stress, damage or other signals. Although senescence can help prevent uncontrolled cell proliferation and support tissue repair, the accumulation of senescent cells is associated with aging, chronic inflammation and age-related diseases. Senescent cells can influence surrounding tissues through the senescence-associated secretory phenotype (SASP), which includes inflammatory molecules, growth factors and other signaling substances. These signals can sometimes induce paracrine senescence, a process in which senescent cells promote senescence in nearby, previously proliferating cells. However, not all senescent cells produce the same inflammatory signals. Cells expressing high levels of p16INK4A, a protein involved in regulating cell-cycle progression, can enter a stable growth-arrested state without developing the classical inflammatory SASP. This raises questions about how these cells communicate with their surroundings and potentially influence tissue aging. To investigate this, the researchers examined small extracellular vesicles, membrane-bound particles that transport proteins, nucleic acids and lipids between cells. These vesicles act as biological messengers, transferring molecular information that can influence the behavior of recipient cells.

BUFFALO, NY — October 28, 2026 — A new #research paper was #published in Volume 18 of Aging on October 6, 2026, titled “Body composition, but not morphological masculinity, is associated with biological aging markers in middle-aged men.” The study found that masculine physical characteristics were not independently associated with biological aging markers in middle-aged men. Instead, body composition, particularly fat-free mass percentage and body fat distribution, showed stronger relationships with inflammation and growth hormone levels. However, these associations disappeared after adjusting for adiposity, suggesting that body fat may help explain the observed relationships. The research was led by first and corresponding author Agnieszka Żelaźniewicz, affiliated with the University of Wroclaw. Aging involves changes in hormonal regulation, immune function, metabolism and body composition. In men, testosterone influences the development of masculine physical characteristics, muscle mass and reproductive function. However, its relationship with biological aging remains unclear, with evidence suggesting both potentially beneficial and harmful effects depending on physiological conditions. Some evolutionary theories propose that greater investment in reproductive characteristics may come at the expense of long-term bodily maintenance. According to the limited soma hypothesis, resources devoted to reproductive competition could reduce those available for cellular repair and maintenance, potentially accelerating aging. Traits such as broad shoulders, muscularity, facial proportions and physical strength are influenced to varying degrees by androgen signaling. If developing and maintaining these characteristics carries long-term physiological costs, men with more pronounced masculine traits might be expected to show signs of accelerated biological aging.

Aging is shaped not only by changes in DNA and metabolism but also by the gradual accumulation of proteins that cells struggle to remove. One striking example is Progerin, an abnormal form of lamin A that accumulates at the nuclear periphery in Hutchinson-Gilford Progeria Syndrome, or HGPS. A new study shows that expressing this human protein in budding yeast reproduces several aging-related cellular defects and creates a simple experimental system for studying how toxic proteins accumulate and affect lifespan. A research paper published in Volume 18 of Aging titled “Modeling premature aging in yeast via the expression of Progerin,” developed a yeast model in which human Progerin and its normal counterpart, lamin A, were expressed as fluorescent fusion proteins. The study was led by first author Zachery R. Belak of the University of Saskatchewan, with corresponding author Troy AA. Harkness, affiliated with the University of Saskatchewan and the University of Alberta. The researchers found that Progerin localized to the yeast nuclear membrane, slowed cellular growth, shortened chronological lifespan, increased genomic instability, and was preferentially retained in older mother cells. Together, these findings suggest that yeast can reproduce several cellular consequences associated with Progerin accumulation despite lacking the conventional nuclear lamina found in human cells.
