摘要: 目的: 体外实验研究新型格列酮类化合物ANY2对糖代谢的影响。方法: 采用高浓度胰岛素持续作用肝癌细胞株( HepG2)24 h 建立胰岛素抵抗模型( IR-HepG2),并观察ANY2对细胞葡萄糖消耗(GC) 、对细胞内糖原含量、糖异生及糖酵解作用的影响。结果: ANY2能显著增加 IR-HepG2在高、中、低糖条件下的葡萄糖消耗, 并呈明显的剂量依赖性;增加 IR-HepG2细胞内糖原含量,但与模型组相比,仅在高浓度差异有统计学意义;减少IR-HepG2 细胞以乳酸为底物的糖异生量;提高糖酵解作用中IR-HepG2细胞乳酸的生成和细胞内丙酮酸激酶(PK) 活力。结论: ANY2可显著改善IR-HepG2 细胞的糖代谢作用。

Abstract: AIM: To investigate the effects of a novel thiazolidinedione ANY2 on glycometabolism in HepG2 cells .METHODS: HepG2 cells are exposed to high concentrations of insulin for 24 h to build the model of insulin-resistance (IR-HepG2) .The effects of ANY2 , including glucose consumption (GC) , glucone-ogenesis and glucolysis were tested in this model.RESULTS: ANY2 could dose-dependently enhance GC in IR-HepG2 cells at high, medium and low levels of glucose.Compared with Modle Group, ANY2 increased IR-HepG2 cells glycogen synthesis significantly only in high dose group .It inhibited gluconeogenesis from lac-tic acid, but increased the production of lactic acid and the activity of pyruvate kinase (PK) in glucolysis.CONCLUSION: Compound ANY2 has remarkable ef-fects on improving glycometabolism in IR-HepG2 cells.
