Sirtuin activation (via overexpression or activators like resveratrol/STACs) delays cellular senescence and extends organismal lifespan in model organisms, primarily through DNA repair, telomere maintenance, and interaction with longevity pathways like IIS and AMPK.

Focus on lifestyle factors that naturally boost Sirtuin activity, such as calorie restriction and exercise, which increase NAD+ levels and activate AMPK. While supplements like resveratrol are popular, their direct efficacy in humans is unproven and potentially mediated by off-target effects. Prioritize sleep, stress management, and balanced nutrition to support genomic stability.

ModerateSupportsMEDIUM confidence
Sirtuin is an essential factor that delays cellular senescence and extends the organismal lifespan through the regulation of diverse cellular processes. Suppression of cellular senescence by Sirtuin is mainly mediated through delaying the age-related telomere attrition, sustaining genome integrity and promotion of DNA damage repair.
