摘要 目的:观察前列腺素E1(prostaglandin E1,PGE1)对高糖培养小鼠肾脏足细胞肾素受体(renin receptor,RR)表达的影响。方法:体外培养和分化小鼠足细胞,随机分为4组分别以0 ng/ml、1 ng/ml、10 ng/ml、20 ng/ml浓度的PGE1进行干预24 h,以Western印迹法、实时定量PCR(quantitative PCR,q-PCR)法检测RR表达的情况。结果:各组分别加不同浓度的PGE1后对照组、高渗组和高糖1组RR mRNA表达总的趋势先上升后下降,高糖2组RR mRNA表达随PGE1浓度升高逐渐下降,10 ng/ml、20 ng/ml组下降有显著意义(P=0.002,P=0.003)。结论:在不同葡萄糖浓度环境中足细胞RR表达不同,对PGE1的干预反应不同,总的趋势为在PGE1低浓度时表达上调,在PGE1高浓度时表达下调,且有显著意义。
