心血管疾病(CVDs)是全球死亡的主要原因,线粒体功能缺陷在很大程度上导致了CVDs的发生。最近的研究表明,sirtuin 3(SIRT3),线粒体NAD+依赖性脱乙酰酶,可以调节线粒体功能和生物合成途径,如葡萄糖和脂肪酸代谢和三羧酸(TCA)循环,氧化应激,和细胞凋亡可逆的蛋白质赖氨酸脱乙酰化。SIRT3调节葡萄糖和脂质代谢并维持心肌ATP水平,从而保护心脏免受代谢紊乱的影响。SIRT3还可以保护心肌细胞免受氧化应激介导的细胞损伤,并阻断心脏肥大的发展。最近的报告显示,SIRT3参与了几种心脏病的保护。本文就SIRT3的相关研究进展及其在心血管疾病防治中的作用进行综述。
Cardiovascular diseases (CVDs) are the leading causes of death worldwide, and defects in mitochondrial function contribute largely to the occurrence of CVDs. Recent studies suggest that sirtuin 3 (SIRT3), the mitochondrial NAD+-dependent deacetylase, may regulate mitochondrial function and biosynthetic pathways such as glucose and fatty acid metabolism and the tricarboxylic acid (TCA) cycle, oxidative stress, and apoptosis by reversible protein lysine deacetylation. SIRT3 regulates glucose and lipid metabolism and maintains myocardial ATP levels, which protects the heart from metabolic disturbances. SIRT3 can also protect cardiomyocytes from oxidative stress-mediated cell damage and block the development of cardiac hypertrophy. Recent reports show that SIRT3 is involved in the protection of several heart diseases. This review discusses the progress in SIRT3-related research and the role of SIRT3 in the prevention and treatment of CVDs.
