摘  要:
自噬是机体维持自身稳态的一种重要生理活动,当体内氨基酸或葡萄糖等营养缺乏时,细胞会启动自噬。自噬受到多种信号通路的调节,哺乳动物雷帕霉素靶蛋白复合体C1(m TORC1)信号通路是其中重要的一条,它可以使自噬相关基因13(Atg13)磷酸化,抑制自噬起始。本文将围绕近年来报道的氨基酸缺乏诱导细胞自噬的m TORC1信号通路,包括小G蛋白、腺苷酸活化蛋白激酶(AMPK)、微小RNA(miRNA)、氨基酰-tRNA合成酶在其中的作用等研究进展进行综述。

摘  要:
Autophagy is an important physiological activity for keeping organism steady.Cell will active the autophagy when the nutrient as amino acid and glucose deficiency.The autophagy is regulated by many signal pathways,and mammalian target of rapamycin complex 1(m TORC1) is one of the important pathway,it can make autophagy factor autophagy-related gene 13(Atg13) phosphorylation to inhibit autophagy starting.In this review,we summarized the results and conclusions from recent works on amino acid-mediated autophagy via the m TORC1 signal pathway including small G protein,adenosine 5 monophosphate-activated protein kinase(AMPK),microRNA(miRNA) and aminoacyl-tRNA synthetase.
