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
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.
