肥胖的记忆储存在脂肪细胞中
在人类中,由于生活方式干预、药物治疗或减肥手术而导致的体重减轻往往伴随着体重反弹。人们认为,细胞保留了一种致肥记忆,使身体容易回到以前的肥胖水平;然而,这种效应背后的机制尚不清楚。一项新的研究表明,人类和小鼠的脂肪细胞在减肥后会保留转录变化,小鼠的脂肪细胞会保留肥胖的表观遗传记忆,这可能与体重反弹有关。von meyen, Hinte和Castellano-Castillo解释说:“我们发现许多细胞类型,但主要是脂肪细胞,内皮细胞和前体细胞,在人类脂肪组织中保留了转录变化。”研究人员在减肥前后的小鼠样本中观察到类似的变化。肥胖导致数千个基因位点发生表观遗传变化,其中许多变化在体重减轻后仍然存在。von meyen, Hinte和Castellano-Castillo说:“例如,应该活跃的启动子保持沉默,增强子景观被重塑,这表明脂肪细胞确实保留了肥胖的表观遗传记忆。”
