摘要
目的:探讨高糖对人肾小球系膜细胞细胞间黏附分子1(ICAM-1)表达的影响及茶多酚对其干预作用。方法:将培养的系膜细胞分为正常对照组、高糖组、茶多酚干预组和茶多酚对照组,分别在0、12、36h采用RT-PCR法和免疫细胞化学法检测茶多酚对高糖条件下系膜细胞内ICAM-1mRNA及蛋白表达的影响。结果:高糖组系膜细胞ICAM-1mRNA和蛋白的表达比正常对照组均增加(P<0.05);茶多酚干预组比高糖组有明显下降(P<0.05)。结论:高糖可导致人肾小球系膜细胞ICAM-1表达的增加,而茶多酚可有效干预此效应。
Objective:To investigate the effects of high glucose on the expression of ICAM-lmRNA in human mesangial cells and the intervention of tea polyphenols (TPs). Methods:Human mesangial cells were cultured in DMEM media containing high glucose with or without TPs for 0,12,36 hours,respectively, The mRNA and protein expression of ICAM-1 were measured by RT-PCR and immunocytochemistry. Results:The mRNA and protein expression of ICAM-1 of the cells increased significantly in high glucose medium (P 〈 0.05). However,TPs inhibited the expression (P 〈 0.05). Conclusion:High glucose contributes to the increase of ICAM-1 expression in human mesangial cells. TPs can reduce high glucose-induced expression of ICAM-1.
