摘 要:摘 要:Sirt1 是依赖烟碱胺腺嘌呤二核苷酸(NAD+) 的第III 类组蛋白去乙酰化酶。在心肌细胞中,Sirt1 通过去乙酰化相关因子增强细胞抵抗氧化应激的能力、减少细胞凋亡、减轻炎症反应、调节能量代谢、协调心脏舒缩功能,发挥心肌保护作用。现主要对Sirt1 的相关信号通路及其心肌保护作用研究进展进行综述。

Abstract: Abstrat: Sirt1, a member of the NAD+-dependent class III histone deacetylase family, plays an important role in metabolism, aging and apoptosis. In cardiomyocytes, Sirt1 can enhance the resistance of oxidative stress, inhibit cell apoptosis, relieve inflammation, regulate energy metabolism and coordinate the diastolic and systolic function of the heart through deacetylasing some special factors, thus playing a vital role in myocardial protection. This article will summary the signal pathway of sirt1 and the current research progress of Sirt1 in myocardial protection.
