Reduced Circulating Insulin Enhances Insulin Sensitivity in Old Mice and Extends Lifespan
1 Jul 2017
Abstract excerpt
The causal relationships between insulin levels, insulin resistance, and longevity are not fully elucidated. Genetic downregulation of insulin/insulin-like growth factor 1 (Igf1) signaling components can extend invertebrate and mammalian lifespan, but insulin resistance, a natural form of decreased insulin signaling, is associated with greater risk of age-related disease in mammals. We compared Ins2 +/− mice to...
