In Whales, a Long Life Absent Cancer Results From Superior DNA Repair Mechanisms
Researchers have identified that bowhead whales, which can live over 200 years, exhibit an unusually robust DNA repair system that underpins their low cancer incidence. Unlike elephants, which rely on multiple TP53 copies, whales appear to use alternative genome‑maintenance pathways to counteract the mutational load of their massive bodies and long lifespans. The findings deepen our understanding of Peto's paradox and suggest that superior DNA repair is a key longevity factor in large mammals. The study opens a speculative avenue for translating these mechanisms into human anti‑cancer strategies.
