摘要
SIRT1(沉默信息调节因子2相关酶I)是依赖于辅酶NAD+的去乙酰化酶,不仅与衰老、凋亡、DNA修复有关,还与不同营养应激状态的细胞代谢转换相关。SIRT1和AMPK(腺苷酸活化蛋白激酶)是细胞内的能量感受器,通过磷酸化、去乙酰化调节着PGC-1α的活性。骨骼肌AMPK/SIRT1/PGC-1α轴的活性调控直接影响着其下游相关基因的表达,与胰岛素抵抗的发生与发展密切相关。
Silent information regulation factor 2 related enzyme I (SIRT1) is a coenzyme NAD+ dependent deacetylase, not only related to aging, dying and DNA repairing, but also correlative with cellular metabolic transformation in different nutrition stress states. SIRT1 and AMPK are energy receptors in cells, regulating the activity of PGC- 1α by means of phosphorylation and deacetylation. The regulation of the activity of the AMPK/SIRT 1/PGC- 1α axis directly affects the expression of its downstream genes related, being closely related to the occurrence and development of insulin resistance.
