在首次报告后的70多年里,热量限制作为最一致的非药物干预措施一直很强,可以延长寿命并防止代谢疾病。在热量限制可能起作用的不同机制中,Sir 2/SIRT 1(沉默信息调节子2/沉默信息调节子T1)由于其将代谢状态的感知与适应性转录输出整合的能力而获得了主要关注。本文综述了收集的证据表明,Sir 2/SIRT 1是热量限制的有益影响的关键调解人,并解决了仍然需要回答的主要问题,以巩固这一假设。
More than 70 years after its initial report, caloric restriction stands strong as the most consistent non-pharmacological intervention increasing lifespan and protecting against metabolic disease. Among the different mechanisms by which caloric restriction may act, Sir2/SIRT1 (Silent information regulator 2/Silent information regulator T1) has gained major attention due to its ability to integrate the sensing of the metabolic status with adaptative transcriptional outputs. This review focuses on gathered evidence suggesting that Sir2/SIRT1 is a key mediator of the beneficial effects of caloric restriction and addresses the main questions that still need to be answered to consolidate this hypothesis.
