摘要 近年来,代谢性疾病成为影响人类健康的重要因素,如肥胖、糖尿病、非酒精性肝炎、代谢性心血管疾病等。代谢性疾病的发病率逐年上升,严重威胁人类健康。代谢性疾病的发生与基因表达的深刻改变有关。在遗传和环境因素的影响下,表观遗传修饰脱氧核糖核酸(deoxyribonucleic acid,DNA)甲基化通过调节基因表达,影响疾病的发生与发展。肠道菌群在调节宿主生理系统代谢反应中发挥着至关重要的作用,肠道菌群通过产生大量代谢物,促进宿主生理机能,维持肠道屏障功能,促进肠道激素和肠脑轴的分泌。肠道菌群代谢产物短链脂肪酸还可通过提供甲基供体等,诱导DNA甲基化;与肠道菌群和其他相关代谢通路有关的DNA甲基化与代谢性疾病的发展存在密切关系。本文旨在阐述代谢性疾病的发病机制,为寻找有效干预手段提供新的研究线索和思路。
