Sirtuins是一种高度保守的组蛋白/蛋白去乙酰化酶家族,其活性可以延长酵母菌、蠕虫和苍蝇等模式生物的寿命。在哺乳动物细胞中,7种sirtuins (SIRT1 - 7)调节不同的代谢和应激反应途径,SIRT1和SIRT3在心血管系统中被广泛研究。SIRT1和SIRT3分别主要位于细胞核和线粒体中。它们参与与心力衰竭发展相关的生物学功能,包括调节能量产生、氧化应激、细胞内信号、血管生成、自噬和细胞死亡/存活。新出现的证据表明,这两种sirtuins在心脏衰竭中起着保护作用。在这里,我们总结了sirtuin在心脏功能的最新知识,并讨论了其在心力衰竭治疗中的转化。
Sirtuins are a highly conserved family of histone/protein deacetylases whose activity can prolong the lifespan of model organisms such as yeast, worms and flies. In mammalian cells, seven sirtuins (SIRT1–7) modulate distinct metabolic and stress-response pathways, SIRT1 and SIRT3 having been most extensively investigated in the cardiovascular system. SIRT1 and SIRT3 are mainly located in the nuclei and mitochondria, respectively. They participate in biological functions related to development of heart failure, including regulation of energy production, oxidative stress, intracellular signaling, angiogenesis, autophagy and cell death/survival. Emerging evidence indicates that the two sirtuins play protective roles in failing hearts. Here, we summarize current knowledge of sirtuin functions in the heart and discuss its translation into therapy for heart failure.
