摘要 目的:探讨高糖环境中人近端肾小管上皮细胞(HK-2)RANTES(regulated upon activation normal Tcell expressed and secreted)和转化生长因子β1(TGF-β1)表达变化及辛伐他汀(Sim)的干预作用。方法:原代培养HK-2分为正常糖对照组(NG)、甘露醇组(MG)、高糖组(HG)、HG+Sim2μmol/L干预组(HG+Sim2)、HG+Sim4μmol/L干预组(HG+Sim4),RT-PCR法测定细胞RANTES和TGF-β1mRNA表达,ELISA法检测细胞上清液中RANTES、TGF-β1蛋白含量。结果:RANTES、TGF-β1的mRNA和蛋白在NG及MG仅有少量表达,而在HG则明显升高(P<0.05);加入Sim后,上述表达均较前下降(P<0.05),具有浓度依赖性。各组HK-2表达的RANTES和TGF-β1无论是mRNA还是蛋白之间均存在显著正相关(P<0.01)。结论:高糖促进HK-2RANTES、TGF-β1的表达,而Sim明显抑制高糖环境中上述因子的过度表达,发挥肾脏保护作用。
