It is generally agreed that adipocytes originate from mesenchymal stem cells in what can be divided into two processes: determination and differentiation. In the past decade, many factors associated with epigenetic signals have been proved to be pivotal for the appropriate timing of adipogenesis progression. A large number of coregulators at critical gene promoters set up specific patterns of DNA methylation, histone acetylation and methylation, and nucleosome rearrangement, that act as an epigenetic code to modulate the correct progress of adipocyte differentiation and adipogenesis during adipogenesis. In this review, we focus on the functions and roles of epigenetic processes in preadipocyte differentiation and adipogenesis.
人们普遍认为脂肪细胞来源于间充质干细胞,可以将其分为两个过程:决定和分化。在过去的十年中,许多与表观遗传信号相关的因素已被证明对于脂肪生成进展的适当时间至关重要。在关键基因启动子处的大量核心调节剂建立了特定的 DNA 甲基化、组蛋白乙酰化和甲基化以及核小体重排模式,作为一种表观遗传密码,调节脂肪细胞分化和脂肪生成过程中脂肪细胞分化的正确进展。在这篇综述中,我们重点讨论了表观遗传过程在前脂肪细胞分化和脂肪生成中的功能和作用。
