摘要 目的研究高糖对血管内皮细胞增殖及肝细胞生长因子(HGF)mRNA表达的影响。方法依据人血管内皮细胞(EC304)分为低糖组、高糖组。加入条件培养基6 h,12 h,24 h,48 h,96 h后,采用MTT法检测细胞增殖或凋亡,返转录聚合酶链反应(RT-PCR)检测HGFmRNA表达水平。结果各组细胞增殖及HGFmRNA表达6 h无明显差别,作用12 h高糖组细胞增殖及HGFmRNA的表达较对照组明显增强,且随着高糖浓度的增加,细胞增殖明显增强,致24 h达高峰,48 h被抑制,细胞数量较24 h明显减少,出现抑制细胞增殖的现象,而HGFmRNA的表达24 h开始下降。结论长期高糖诱导内皮细胞凋亡、下调HGFmRNA的表达;促进动脉粥样硬化。
