Ribosome biogenesis is initiated by RNA polymerase I Pol Imediated synthesis of preribosomal RNA prerRNA Pol I activity was previously linked to longevity but the underlying mechanisms

Reducing the metabolic burden of rRNA synthesis promotes healthy

Limiting Pol I activity extends lifespan more potently than direct repression of protein synthesis and confers geroprotection even when initiated late in life showcasing this intervention as an effective longevity and metabolic health treatment not limited by aging Ribosome biogenesis is initiated by RNA polymerase I Pol Imediated synthesis of preribosomal RNA prerRNA Pol I activity

Reducing The Metabolic Burden Of Rrna Synthesis Promotes

Our indepth analyses demonstrated that curtailment of prerRNA synthesis attenuates metabolic aging and stabilizes energy turnover providing an ATP surplus for healthy homeostasis Importantly we found a similar energy preservation effect upon depletion of the ribosomal protein RPS15 previously linked to life span extension in C elegans 30
