Evolutionary analysis of the mTOR pathway provide insights into lifespan extension across mammals

Abstract excerpt

BACKGROUND: Lifespan extension has independently evolved several times during mammalian evolution, leading to the emergence of a group of long-lived animals. Though mammalian/mechanistic target of rapamycin (mTOR) signaling pathway is shown as a central regulator of lifespan and aging, the underlying influence of mTOR pathway on the evolution of lifespan in mammals is not well understood. RESULTS: Here, we...
