The guardian of the genome (p53) elicits cell-cycle checkpoints in response to genotoxic stress. p53 also induces a metabolic checkpoint by inhibiting the mammalian target of rapamycin complex 1 (mTORC1). Recent results by Budanov and Karin, (2008) reveal that p53 exerts its effect on mTORC1 through sestrin1 and sestrin2.
基因组守护者(p53)在响应基因毒性应激时引发细胞周期检查点。p53还通过抑制雷帕霉素复合物1(mTORC1)的哺乳动物靶点来诱导代谢检查点。布达诺夫和卡林(2008年)最近的研究结果表明,p53通过 sestrin1 和 sestrin2 对 mTORC1 发挥作用。
