Mammalian target of rapamycin (mTOR) controls cell growth and metabolism in response to nutrients, energy, and growth factors. Recent findings have placed the lysosome at the core of mTOR complex 1 (mTORC1) regulation by amino acids. Two parallel pathways, Rag GTPase-Ragulator and Vps34-phospholipase D1 (PLD1), regulate mTOR activation on the lysosome. This review describes the recent advances in understanding amino acid-induced mTOR signaling with a particular focus on the role of mTOR in insulin resistance.
雷帕霉素哺乳动物靶蛋白(mTOR)可根据营养物质、能量和生长因子来控制细胞生长与代谢。最近的研究发现,溶酶体是氨基酸对mTOR复合物1(mTORC1)调控的核心。两条平行途径,即Rag GTP酶-Ragulator和Vps34-磷脂酶D1(PLD1),在溶酶体上调节mTOR的激活。本综述描述了在理解氨基酸诱导的mTOR信号传导方面的最新进展,特别关注mTOR在胰岛素抵抗中的作用。
