目的:探讨内皮细胞微粒(Endothelial microparticles
EMPs)对人脐静脉内皮细胞(Human umbilical vein endothelialcells
HUVECs)血管细胞粘附分子-1(Vascular cellular adhesion molecule-1
VCAM-1)和细胞间粘附分子-1(Intercellular adhe-sion molecule 1
ICAM-1)表达的影响。方法:取生长良好的第4、5代HUVECs
将细胞以1×105个/ml密度接种于5 cm2的培养皿中
待细胞生长近80%融合时进行干预。按0、1×102、1×103、1×104、1×105个/ml浓度的EMPs进行分组及刺激
每组12个样本。在共同培养24 h后收集细胞。分别采用实时荧光定量聚合酶链反应和蛋白免疫印迹方法检测VCAM-1和ICAM-1 mRNA和蛋白的表达。结果:HUVECs受EMPs刺激
VCAM-1和ICAM-1 mRNA及蛋白表达显著增加
且EMPs的这种作用呈浓度依赖性增强(均P<0.05)。结论:EMPs能上调HUVECs VCAM-1和ICAM-1的表达
EMPs不仅是内皮功能障碍的标记物
还能加重内皮功能损害。
Objective:To examine the effects of endothelial microparticles(EMPs)on the expressions of vascular cell adhesion molecule 1(VCAM-1) and intercellular adhesion molecule(ICAM-1) in human umbilical vein endothelial cells(HUVECs).Methods:HUVECs at passage 4 to 5 were incubated for 24 h with EMPs(0
1×102
1×103
1×104
1×105/ml).Quantitative real-time polymerase chain reaction and Western blotting were used to detect expressions of mRNA and protein of ICAM-1 and VCAM-1 respectively.Results:Both two detection methods showed that EMPs stimulation significantly induced the mRNA and protein expressions of VCAM-1 and ICAM-1 in HUVECs in a dose-dependent manner.Conclusion:EMPs can induce the expressions of VCAM-1 and ICAM-1 in a dose-dependent manner.These findings suggest that EMPs may have adverse effects in modulating inflammatory response in atherosclerosis.
