mTOR Signaling in Growth, Metabolism, and Disease

Cell. 2017 Mar 9;168(6):960-976. doi: 10.1016/j.cell.2017.02.004.

Abstract

The mechanistic target of rapamycin (mTOR) coordinates eukaryotic cell growth and metabolism with environmental inputs, including nutrients and growth factors. Extensive research over the past two decades has established a central role for mTOR in regulating many fundamental cell processes, from protein synthesis to autophagy, and deregulated mTOR signaling is implicated in the progression of cancer and diabetes, as well as the aging process. Here, we review recent advances in our understanding of mTOR function, regulation, and importance in mammalian physiology. We also highlight how the mTOR signaling network contributes to human disease and discuss the current and future prospects for therapeutically targeting mTOR in the clinic.

Keywords: aging; cancer; cell growth; diabetes; mTOR; mTORC1; mTORC2; metabolism; nutrients; signaling.
