摘要:

沉默信息调节因子1(SIRT1)是一种高度保守的NAD+依赖性脱乙酰酶,不仅在脂肪组织中广泛表达,更在肥胖与胰岛素抵抗(IR)的发生发展中发挥关键作用。脂肪组织中的SIRT1通过抑制炎症反应、调节脂质代谢、促进脂肪褐变和血管生成,以及恢复胰岛素信号通路等多种机制,显著改善肥胖及相关代谢异常。靶向脂肪组织递送SIRT1激动剂白藜芦醇(Res)可进一步增强其对肥胖和IR的治疗效果。本文系统概述了SIRT1的分子结构基础及其在多器官中的作用,深入梳理了其在脂肪组织中多靶点调控肥胖与IR的分子网络,并总结了以Res为代表的SIRT1激动剂的不同脂肪靶向递送策略,以期为代谢性疾病的治疗提供新视角与研究思路。

Abstract:

?Silent mating type information regulation 2 homolog 1(SIRT1), a highly conserved NAD?-dependent deacetylase, is widely expressed in adipose tissue and plays a critical role in the pathogenesis of obesity and insulin resistance (IR). In adipose tissue, SIRT1 ameliorates obesity and related metabolic disorders through multiple mechanisms, including suppression of inflammatory responses, regulation of lipid metabolism, promotion of adipose browning and angiogenesis, and restoration of insulin signaling pathways. Targeted delivery of the SIRT1 agonist resveratrol (Res) to adipose tissue further enhances its therapeutic efficacy against obesity and IR. This article systematically reviews the molecular basis of SIRT1's structure, along with its physiological functions across various organ systems, provides a comprehensive elucidation of its multi-target regulatory network in adipose tissue in the context of obesity and IR, and summarizes various adipose-targeting delivery strategies for SIRT1 agonists, with a focus on Res. The aim is to offer new perspectives and research directions for the treatment of metabolic diseases.

Key words: obesity, insulin resistance, silent information regulator 2 homolog 1, targeted therapy
