Genomic instability and DNA damage accumulation are causative drivers of organismal aging and cellular senescence, rather than merely correlative byproducts.
Focus on maintaining genomic integrity through healthy lifestyle choices like caloric restriction, which has been shown to reduce oxidative damage and extend lifespan in models. Be skeptical of antioxidant supplements as a universal anti-aging solution, as evidence for their efficacy in healthy individuals is mixed or negative. Prioritize strategies that support DNA repair mechanisms and reduce chronic stress on cells.
This evidence suggests that genomic instability plays a causative role in the ageing process.
Why this rating
The paper reviews extensive genetic models (progeroid mice, knockout models) and non-genetic interventions (caloric restriction, antioxidants) that support causality, though conflicting data exists regarding antioxidant efficacy in wild-type models.

- Cellular senescence contributes to organismal aging through two main pathways: depleting tissue self-renewal capacity and disrupting tissue structure/function via inflammatory secretions.Good
- Mitochondrial DNA (mtDNA) mutations cause premature aging in mice primarily through apoptosis and loss of irreplaceable cells, rather than through a vicious cycle of increased oxidative stress.Good
