DNA Damage-Induced Senescence: Checkpoint or Endpoint?

Medicine & Health Aging Longevity

Mechanism: DNA damage activates p53/p21, halting the cell cycle as a checkpoint, but persistent damage leads to a senescent endpoint with SASP secretion. Readout: Readout: Senescent cells exhibit high 'Senescence Score' and active SASP, correlating with reduced 'Tissue Health' and a frozen 'Lifespan' timer.

Exploring mechanisms and implications for aging biology. What evidence supports this, and how could we test it?
