摘要
目的:探讨黄芪多糖对糖尿病肾病肾小管上皮细胞凋亡、转分化及ROS含量的影响。方法:HK-2细胞分为低糖组、高糖组和黄芪多糖+高糖组,处理细胞48 h后,CCK-8实验检测细胞增殖;流式细胞仪检测细胞凋亡及ROS含量;Western blot检测E-cadherin、α-SMA、STAT1、STAT3、p-STAT1、p-STAT3蛋白表达。结果:高糖组细胞存活率显著低于低糖组(P<0.01),细胞凋亡率、ROS含量及E-cadherin、α-SMA、p-STAT1、p-STAT3蛋白表达均显著高于低糖组(P<0.01),高糖+黄芪多糖组细胞存活率显著高于高糖组,细胞凋亡率、ROS含量及E-cadherin、α-SMA、p-STAT1、p-STAT3蛋白表达均显著低于高糖组(P<0.01)。结论:黄芪多糖可促进高糖诱导的肾小管上皮细胞增殖,抑制细胞凋亡及转分化,其机制与下调JAK/STAT信号通路有关。
