Lysosomes Signal Through The Epigenome To Regulate Longevity Across Generations, Qinghao Zhang, Weiwei Dang, Meng C Wang

Faculty, Staff and Students Publications

The epigenome is sensitive to metabolic inputs and crucial for aging. Lysosomes act as a signaling hub to sense metabolic cues and regulate longevity. We find that lysosomal metabolic pathways signal through the epigenome to regulate transgenerational longevity in Caenorhabditis elegans. Activation of lysosomal lipid signaling and lysosomal adenosine monophosphate-activated protein kinase (AMPK) or reduction of lysosomal mechanistic-target-of-rapamycin (mTOR) signaling increased expression of a histone H3.3 variant and increased its methylation on K79, leading to lifespan extension across multiple generations. This transgenerational pro-longevity effect required intestine-to-germline transportation of histone H3.3 and a germline-specific H3K79 methyltransferase, and was recapitulated by …
