Repeated DNA damage response activation is examined in an article exploring whether this proposed aging driver explains cellular senescence and stem-cell decline.
Key Takeaways
- Chronic, mutation-independent overactivation of the DNA damage response (DDR) can dysregulate tumor-suppressor networks and drive aging-related changes.
- Repeated DDR activation likely promotes senescence, stem-cell pool depletion, and systemic inflammaging as mechanistic contributors to aging.
- Rigorous longitudinal, mediation, and head-to-head tests are required to determine how much DDR overactivation meaningfully contributes to degenerative aging.
