The Sir2-p53-IGF link in mammalian life-span control

Description: PUBLIC HEALTH RELEVANCE: Paradoxically, robust growth and bigger size are not necessarily good predictors of a long and healthy life span. Despite the obvious significance of this observation, the mechanism that couples longevity and body size is poorly understood. We propose that it is the tumor suppressor p53 that links these two traits by controlling the switch from anaerobic to aerobic metabolism in stem cells.
