摘要 目的观察蒲黄总黄酮对C2C12骨骼肌细胞葡萄糖消耗及Src蛋白表达的影响。方法将分化成熟的C2C12骨骼肌细胞予含胰岛素及不同终质量浓度蒲黄总黄酮(0、0.1、0.25、0.5 g/L)分别干预处理8、16、24 h后,葡萄糖氧化酶法检测培养上清液葡萄糖浓度。另外,按处理方法将细胞分为对照组和蒲黄总黄酮组,蒲黄总黄酮干预16 h后,予和不予胰岛素刺激30 min,免疫印迹法检测蛋白表达,免疫共沉淀法检测Src相关信号复合物。结果蒲黄总黄酮呈时间和浓度依赖性显著促进了C2C12骨骼肌细胞葡萄糖消耗。蒲黄总黄酮组Src蛋白表达是对照组1.72倍,而蒲黄总黄酮+胰岛素组Src蛋白表达则是胰岛素组1.67倍,差异显著(P<0.01);与胰岛素组比较,蒲黄总黄酮+胰岛素组磷酸化Src蛋白表达水平升高0.54倍,有统计学意义(P<0.01),并且Src相关信号复合物形成也显著提高。结论蒲黄总黄酮提高C2C12骨骼肌细胞葡萄糖消耗,可能与其促进Src蛋白表达及其磷酸化水平和Src相关信号复合物形成有密切关系。
