The mammalian sirtuins (SIRT1-7) are a family of highly conserved nicotine adenine dinucleotide (NAD(+))-dependent deacetylases that act as cellular sensors to detect energy availability. SIRT1 is a multifaceted protein that is involved in a wide variety of cellular processes. SIRT1 is activated in response to caloric restriction, acting on multiple targets in a wide range of tissues. SIRT1 regulates the role of multiple hormones implicated in energy balance, including glucose and lipid metabolism. Here, we review the relevant role of SIRT1 as a mediator of endocrine function of several hormones to modulate energy balance. In addition, we analyze the potential of targeting SIRT1 for the treatment of obesity and type 2 diabetes mellitus.
哺乳动物的沉默调节蛋白(SIRT1 - 7)是一类高度保守的烟酰胺腺嘌呤二核苷酸(NAD(+))依赖性脱乙酰酶,作为细胞传感器来检测能量供应情况。SIRT1是一种多功能蛋白,参与多种细胞过程。SIRT1在热量限制的情况下被激活,作用于广泛组织中的多个靶点。SIRT1调节多种与能量平衡相关的激素的作用,包括葡萄糖和脂质代谢。在此,我们综述SIRT1作为几种激素内分泌功能的介质在调节能量平衡方面的相关作用。此外,我们分析了靶向SIRT1治疗肥胖症和2型糖尿病的潜力。
