SIRT1, a NAD(+)-dependent protein deacetylase that regulates transcription factors involved in key cellular processes, has been implicated as a mediator of the beneficial effects of calorie restriction. In a recent issue of Nature, Milne et al. (2007) describe novel potent activators of SIRT1, whose administration to insulin-resistant animals improves glucose homeostasis.
SIRT1是一种依赖烟酰胺腺嘌呤二核苷酸(NAD(+))的蛋白质脱乙酰酶,可调节参与关键细胞过程的转录因子,被认为是热量限制有益作用的介质。在最近一期的《自然》杂志上,米尔恩等人(2007年)描述了SIRT1的新型强效激活剂,将其给予胰岛素抵抗动物可改善葡萄糖稳态。
