过氧化物酶体增殖物激活受体(PPARs)γ基因已被公认在调控脂肪细胞分化和多种代谢(糖、脂肪、能量代谢等)中起重要作用。它在脂肪、肌肉、肝脏等多种与胰岛素作用有关的组织中表达,并且具备激活后调控涉及葡萄糖的产生、转运、利用及脂肪代谢的调节等基因的表达。PPARγ基因在脂肪细胞分化、糖、脂代谢、动脉粥样硬化形成、炎性反应中起重要作用,从而与T2DM、胰岛素抵抗、肥胖症、心血管疾病和高血压等疾病的发病风险相关。本文综述了PPARγ基因的结构、功能及其多态性与代谢综合征关系的研究进展。 Peroxisome proliferator-activated receptor (PPARs) gamma gene has been recognized as playing an important role in the regulation of adipocyte differentiation and various metabolism (sugar, fat, energy metabolism, etc.). It is expressed in many tissues related to insulin action, such as fat, muscle and liver, and has the regulation of genes involved in the regulation of glucose production, transport, utilization and fat metabolism after activation. The PPARγ gene plays an important role in adipocyte differentiation, carbohydrate and lipid metabolism, atherosclerosis formation and inflammatory reaction, and thus is associated with the risk of developing T2DM, insulin resistance, obesity, cardiovascular diseases and hypertension. This review summarizes the research progress of the relationship between PPARγ gene structure, function and polymorphism and metabolic syndrome.
