White adipocytes store excess energy in the form of triglycerides, whereas brown and beige adipocytes dissipate energy in the form of heat. This thermogenic function relies on the activation of brown and beige adipocyte-specific gene programmes that are coordinately regulated by adipose-selective chromatin architectures and by a set of unique transcriptional and epigenetic regulators. A number of transcriptional and epigenetic regulators are also required for promoting beige adipocyte biogenesis in response to various environmental stimuli. A better understanding of the molecular mechanisms governing the generation and function of brown and beige adipocytes is necessary to allow us to control adipose cell fate and stimulate thermogenesis. This may provide a therapeutic approach for the treatment of obesity and obesity-associated diseases, such as type 2 diabetes.
白色脂肪细胞以甘油三酯的形式储存多余的能量,而棕色和米色脂肪细胞则以热量的形式消耗能量。这种产热功能依赖于棕色和米色脂肪细胞特异性基因程序的激活,这些程序由脂肪选择性染色质结构以及一组独特的转录和表观遗传调节因子协同调控。响应各种环境刺激促进米色脂肪细胞生成也需要许多转录和表观遗传调节因子。更好地理解控制棕色和米色脂肪细胞生成和功能的分子机制对于我们控制脂肪细胞命运和刺激产热是必要的。这可能为治疗肥胖症及肥胖相关疾病(如2型糖尿病)提供一种治疗方法。
