The ability to reverse senescence depends on restoring metabolic flexibility through AMPK reactivation and mTOR cyclical inhibition. Cells that can successfully switch between glycolysis and oxidative phosphorylation achieve reversal; those that cannot only stabilize.
Debate provenance: derived from debate `sess_SDA-2026-04-08-gap-debate-20260406-062101-7751c220` on question: The highest-ranked hypothesis assumes senescence reversibility through metabolic reprogramming, but the debate did not e
Partial metabolic interventions (e.g., mTOR inhibition alone) suppress SASP secretion but leave growth arrest intact because they fail to restore epigenetic architecture at senescence-associated heterochromatin foci (SAHF). Complete NAD+ restoration activates SIRT1, which deacetylates H3K9 and recruits SUV39H1/HP1 to re-establish heterochromatin, allowing silencing of p16INK4a and re-expression of E2F-target proliferation genes. This predicts that single-agent senolytics or mTOR inhibitors halt
