Methods: 3T3-L1 adipocytes and hepatocytes were used to investigate GRb1s action on adiponectin expression and triglyceride (TG)积累。用GRB1治疗喂食高脂饮食的野生型(WT)小鼠和脂联蛋白敲除(KO)小鼠2周。测量了肝脂肪的积累和功能以及胰岛素敏感性。在肝脏和肝细胞中也检测到AMPK的激活。 结果: grb1反转了脂肪细胞中脂肪蛋白细胞蛋白分泌的还原。用GRB1处理的脂肪细胞中的条件培养基(CM)降低了肝细胞中TG积累的积累,该肝细胞部分由脂联蛋白抗体减弱。在KO小鼠中,GRB1诱导的TG含量显着降低,Alt和AST被脂联蛋白的缺失阻塞。在KO小鼠中,OGTT,ITT和HOMA-IR指示的GRB1诱导的胰岛素敏感性的升高也被削弱了。 CM处理显着增强了肝细胞中AMPK的磷酸化,但没有GRB1处理。 Likewise, the phosphorylation of AMPK in liver of the WT mice was increased by GRb1, but not in the KO mice. Conclusions: The up-regulation of adiponectin by GRb1 contributes to the amelioration of liver steatosis and insulin resistance, which further elucidates GRB1对肥胖的有益作用的新机制。
