表观遗传修饰对脂肪组织产热的调控进展

Progress on the epigenetic regulation of adipose tissue thermogenesis

棕色和米色脂肪组织的激活可以增加葡萄糖、脂肪酸等底物的消耗,调节全身的能量平衡,改善肥胖病、2型糖尿病等代谢性疾病。研究产热脂肪组织的调控机制,将为代谢性疾病的防治提供新策略。目前研究已表明,表观遗传修饰在脂肪组织的分化和产热等方面发挥重要的调控作用。本文从DNA甲基化、组蛋白修饰、染色质重塑和非编码RNA等方面,对表观遗传修饰在脂肪组织的分化和产热等方面发挥的调控作用进行综述,为深入研究脂肪组织的激活提供新思路。

The activation of brown adipose tissues and beige adipose tissues can utilize more substrates, including glucose and fatty acids, regulate the energy balance of the whole body and improve metabolic diseases such as obesity and type Ⅱ diabetes. Elucidating the regulatory mechanisms underlying the thermogenic adipose program may provide excellent targets for therapeutics against metabolic diseases. The current studies have indicated that epigenetic modifications are vital for regulating differentiation and thermogenesis of adipose tissues. In this review, we summarize the recent progress of epigenetic modifications in adipose tissue development and thermogenesis from the aspects of DNA methylation, histone modification, chromatin remodeling, and non-coding RNAs in order to provide new ideas for further studying the activation of adipose tissues.
