New Aging Framework Proposes Epigenetic Regulation as a Major Limit on Human Lifespan
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.
