The sirtuins (SIRT1-7) are a family of nicotinamide adenine dinucleotide (NAD)-dependent deacylases with remarkable abilities to prevent diseases and even reverse aspects of ageing. Mice engineered to express additional copies of SIRT1 or SIRT6, or treated with sirtuin-activating compounds (STACs) such as resveratrol and SRT2104 or with NAD precursors, have improved organ function, physical endurance, disease resistance and longevity. Trials in non-human primates and in humans have indicated that STACs may be safe and effective in treating inflammatory and metabolic disorders, among others. These advances have demonstrated that it is possible to rationally design molecules that can alleviate multiple diseases and possibly extend lifespan in humans.
沉默调节蛋白(SIRT1 - 7)是一类依赖烟酰胺腺嘌呤二核苷酸(NAD)的去酰基酶家族,具有预防疾病甚至逆转衰老某些方面的显著能力。经过基因工程改造以表达额外拷贝的SIRT1或SIRT6的小鼠,或用白藜芦醇和SRT2104等沉默调节蛋白激活化合物(STACs)或NAD前体处理的小鼠,其器官功能、身体耐力、抗病能力和寿命都有所改善。在非人类灵长类动物和人类中进行的试验表明,STACs在治疗炎症和代谢紊乱等疾病方面可能是安全有效的。这些进展表明,合理设计能够缓解多种疾病并可能延长人类寿命的分子是有可能的。
