On the 1.3% MET-enriched diet, Ames dwarf mice outlived wild-type mice by 69% with median lifespans for Ames mice at 937 days (95% CI 799–1068 days) and 556 days (95% CI 505–649 days) for wild-type mice. The dwarf mice also exhibited a 48% extensionin maximal lifespan
WebMice are excellent experimental models for genetic research and are being used to investigate the genetic component of organismal aging.
