Epigenetic Drift of H3K27me3 in Aging Links Glycolysis to Healthy Longevity


ABSTRACT: We adapted ChIP-Rx method established in cells to fly tissues for quantitative ChIP-seq. We found the deposition of H3K27me3 during aging loses fidelity, resulting its propagation across the epigenome; lowering H3K27me3 by PRCs-deficiency promotes healthy lifespan by mitigating this trend. Quantitative multi-omic analysis converges on a central role of glycolysis, linking H3K27me3 dynamics to the regulation of glycolytic genes, which correspondingly rewire cellular metabolic homeostasis including energy and redox potential that impact lifespan and adult fitness.
