Metabolic regulation of human DNA methylation clocks
Description: NARRATIVE Epigenetic clocks are widely used in geroscience but little known about their modifiability and behavior across the lifespan. Here we use a human cellular lifespan system that recapitulates key hallmarks of human aging (DNA methylation signatures, ccf-mtDNA, inflammation) to map individualized trajectories in the rate of epigenetic aging among cells from healthy women and men, in response to glucocorticoid stress, and to targeted mitochondrial dysfunction. These high-resolution longitudinal multi-system data will provide new insights into inter-individual differences in aging trajectories, the modifiability of epigenetic clocks, and provide causal evidence for the of mitochondrial dysfunction as a potential biological determinant of epigenetic aging.
