摘要
目的探讨肿瘤坏死因子α(TNF-α)对大鼠肾小球系膜细胞(RGMC)中纤溶酶原激活物抑制物1(PAI-1)和胞间黏附分子1(ICAM-1)表达的影响以及利拉鲁肽(Liraglutide,Li)的干预作用。方法将培养的RGMC株分为6组,分别为正常对照组、TNF-α组、Li低浓度(10 nmol/L)组、中浓度(100 nmol/L)组、高浓度(1000 nmol/L)组,以及吡咯烷二硫代氨基甲酸盐(PDTC)组。用ELISA法测定各组RGMC的PAI-1以及ICAM-1蛋白表达。用RT-PCR法测定各组RGMC的PAI-1以及ICAM-1基因表达。结果 TNF-α可上调RGMC中PAI-1、ICAM-1蛋白及基因表达(均P<0.05),利拉鲁肽可抑制TNF-α诱导的RGMC中PAI-1、ICAM-1蛋白及基因的高表达(均P<0.05)。与TNF-α组比较,PDTC组PAI-1、ICAM-1表达量显著减少(均P<0.05)。结论利拉鲁肽可减轻体外培养RGMC中TNF-α诱导的PAI-1和ICAM-1表达。
