Somatic mutation rates scale with lifespan across mammals
Yearbook of pediatric endocrinology(2023)
摘要
In Brief: To document variations in rates of somatic mutations, the authors performed whole-genome sequencing of DNA from cells of intestinal crypts across 16 diverse mammalian species, spanning huge 40 000-fold variations in body mass and 30-fold variations in lifespan. The somatic mutation rates per year varied greatly across species and showed a much stronger inverse relationship with species lifespan than with species body mass.
