摘要 目的:观察焦油和尼古丁对人脐静脉内皮细胞(HUVECs)细胞间粘附分子-1(ICAM-1)在表达的影响。方法:体外分离培养HUVECs,分别与不同浓度焦油(终浓度分别为1mg/L、10mg/L、20mg/L、50mg/L和不同浓度尼古丁终浓度分别为(10-9 mol/L、10-7 mol/L、10-5 mol/L、10-3 mol/L)共同孵育6h后,收集细胞,用流式细胞技术、实时荧光定量聚合酶链反应(qRT-PCR)检测其ICAM-1蛋白和mRNA表达水平。将不与焦油和尼古丁共培养HUVEC S作为对照组。结果:不同浓度焦油组ICAM-1蛋白和mRNA表达水平均与对照组有明显差异(P<0.05),并随着焦油浓度升高,ICAM-1的蛋白H和mRNA水平也升高(P<0.05)。而尼古丁各浓度组及对照组ICAM-1蛋白和mRNA表达差异均无统计学意义(P>0.05)。结论:焦油可上调HUVECs的ICAM-1表达。
