近年来沉默信息调节蛋白1(silent information regulator protein 1,Sirt1)作为一种保护分子被广泛地研究,其中Sirt1对线粒体功能的调节更是关注的焦点。而线粒体功能障碍又是造成缺血再灌注损伤(ischemia-reperfusion injury,IRI)的关...近年来沉默信息调节蛋白1(silent information regulator protein 1,Sirt1)作为一种保护分子被广泛地研究,其中Sirt1对线粒体功能的调节更是关注的焦点。而线粒体功能障碍又是造成缺血再灌注损伤(ischemia-reperfusion injury,IRI)的关键因素,因此Sirt1与IRI的关系也成为了研究的热点。本文主要从Sirt1增强线粒体抗氧化能力、增加线粒体的生物合成以及抗凋亡等方面论述Sirt1-线粒体途径减轻IRI的相关作用机制。靶向线粒体功能调节将成为减轻IRI的一项重要措施。展开更多
