mTORC1 and IRS1: Another Deadly Kiss

Trends Endocrinol Metab. 2018 Nov;29(11):737-739. doi: 10.1016/j.tem.2018.07.003. Epub 2018 Aug 3.

Abstract

Mechanistic target of rapamycin complex (mTORC)1 is the major regulator of metabolism at the cellular and organismal level. mTORC1-mediated regulatory feedback loops enable adaptation to nutrient and growth factor availability and metabolic demand. In their recent study, Yoneyama et al. have identified and characterized a negative feedback loop from mTORC1 to insulin receptor substrate (IRS)1; the key component of the insulin/insulin-like growth factor (IGF) signaling pathway.

Keywords: IGF-I; IRS1; feedback loops; mTORC1; mTORC2.
