Longevity & AgingBlocking Ferroptosis Slows Aging and Extends Healthy Lifespan Across Species
Researchers at Southwest Medical University found that ferroptosis—iron-dependent cell death driven by lipid peroxidation—progressively worsens during cellular senescence. Using three senescence models in human foreskin fibroblasts (HFF cells), they showed ferroptosis markers rise with aging while GPX4 levels fall. Ferroptosis inducers Erastin and RSL3 accelerated senescence, whereas inhibitors ferrostatin-1 (Fer-1) and liproxstatin-1 (Lip-1) reversed it. In C. elegans, Fer-1 extended both lifespan and healthspan. In both prematurely and naturally aged mice, Fer-1 improved motor function, preserved tissue integrity, and reduced cognitive decline. Crucially, six-plus months of Fer-1 treatment caused no weight gain or tissue damage and actually rejuvenated blood parameters, suggesting a favorable safety profile for long-term anti-aging use.
