摘要 目的:研究人血白蛋白对人近端肾小管上皮细胞(HK-2)血管紧张素转换酶2(ACE2)及血管紧张素转换酶(ACE)表达的影响,探讨白蛋白对肾脏损害的机制。方法:不同浓度人血白蛋白(0、1、5、10、15g/L)分别加入到培养的人近端肾小管上皮细胞培养48h,用RT-PCR法和Western blotting法分别检测HK-2细胞ACE2和ACEmRNA和蛋白表达。结果:正常培养状态下HK-2细胞(空白对照组)存在ACE2mRNA和蛋白表达,加入不同浓度(5-15g/L)的人血白蛋白剂量依赖抑制HK-2细胞ACE2mRNA和蛋白表达(P<0.01)。正常培养状态下HK-2细胞ACEmRNA和蛋白表达水平较低,随着加入白蛋白浓度的增加其表达水平逐渐升高,10g/L白蛋白显著促进了HK-2细胞ACEmRNA和蛋白表达(P<0.05)。结论:在体外培养的HK-2细胞存在ACE及ACE2mRNA和蛋白表达,人血白蛋白可抑制其ACE2表达而促进ACE表达,这可能是白蛋白促肾小管间质损伤及肾小球硬化、间质纤维化的机制之一。
