Levels of histone H4 lysine 16 acetylation (H4K16ac) increase with aging in yeast and interventions that lower its abundance increase lifespan [ 53 ]. WebSep 8, 2024 · The expression of certain genes must therefore be activated or repressed, depending on the fate of the cell. Age-related methylation changes occur either randomly on certain cytosines (“Epigenetic drift”) or on specific regions of DNA where methylation changes are associated with age. The latter are used to measure aging. barbara stiles
