[摘要] 随着糖尿病及代谢综合征的发病率逐年增高,非酒精性脂肪性肝病发病也平行性升高,胰岛素抵抗是这些代谢性疾病的共同发病机制。FGF21是一种重要的糖脂代谢调控因子,可以通过调控MAPK/ERK, PI3K-Akt及PPARγ等重要的细胞信号通路改善胰岛素抵抗。该文总结近年的文献,探讨FGF21的分子机制与生理作用,与糖尿病及NAFLD相关性,明确了FGF21将成为有效治疗糖尿病及NAFLD的新靶点。

[Abstract] As the incidence of diabetes and metabolic syndrome increases year by year, the incidence of non-alcoholic fatty liver disease also increases in parallel. Insulin resistance is the common pathogenesis of these metabolic diseases. FGF21 is an important regulator of glucose and lipid metabolism and can improve insulin resistance by regulating important cellular signaling pathways such as MAPK/ERK, PI3K-Akt, and PPARγ. This article summarizes the literature in recent years and explores the molecular and physiological roles of FGF21, its association with diabetes and NAFLD, and clarifies that FGF21 will become a new target for the effective treatment of diabetes and NAFLD.

成纖维细胞生长因子(Fibroblast growth factors, FGFs)是一组具备多种功能的活性因子,有调控内皮细胞、平滑肌细胞、成纤维细胞的生长、分化和迁移,还可参与组织修复、再生和神经营养等。人类FGFs 家族包括 22 个成员,其中FGF21主要是由肝脏分泌,也可在脂肪、胰腺和肌肉组织中表达,是一种新型脂肪因子,在降低血脂、血糖以及改善胰岛素敏感性等方面有重要的调节作用。 作为一种代谢调控因子,FGF21在肥胖、2 型糖尿病以及非酒精性脂肪性肝病治疗领域有非常重要的价值。该文对此做一综述。
1 非酒精性脂肪性肝病与糖尿病的发病趋势及相关性
非酒精性脂肪性肝病(nonalcoholic fatty liver disease, NAFLD)是除外过量饮酒及其他明确的肝损害因素,与遗传易感性和胰岛素抵抗相关的代谢应激性肝损伤,包括单纯性肝细胞脂肪变性(SS)、非酒精性脂肪性肝炎(NASH)、肝硬化、肝细胞癌等一系列病理类型。NAFLD是全球普遍流行的肝脏疾病,目前我国成人NAFLD患病率逐年升高,与肥胖、2型糖尿病和代谢综合征(MS)的发病率增加相平行。……
