摘要: 目的 探讨氟伐他汀对C反应蛋白(C-reactive protein, CRP)诱导的人脐静脉内皮细胞(human umbilical vein endothelial cells, HUVECs)细胞间黏附分子-1(intercellular adhesion molecule-1,ICAM-1)表达的影响。方法 进行HUVECs原代培养,取第3~6代进行实验。分别以5、10、50和100 mg/L浓度CRP作用HUVECs,分别作用6、12和24h,同时用氟伐他汀10-8、10-7、10-6和10-5mol/L浓度进行干预。用ELISA法测ICAM-1蛋白含量,RT-PCR测ICAM-1mRNA表达。结果 HUVECs对照组有少量ICAM-1蛋白和mRNA表达; CRP组ICAM-1蛋白和 mRNA表达明显增强(p <0.01),且ICAM-1蛋白表达呈浓度和时间依赖性增加(p <0.01);氟伐他汀组ICAM-1蛋白及mRNA 表达明显减弱(p <0.01),且氟伐他汀抑制CRP诱导的ICAM-1蛋白表达呈浓度依赖性(p <0.05)。结论 氟伐他汀可能通过抑制CRP诱导ICAM-1产生,发挥抗动脉粥样硬化形成的作用。

Abstract: Objective To study the effects of Fluvastatin on the expression of intercellular adhesion molecule-1 (ICAM-1) in human umbilical vein endothelial cells (HUVECs) induced by C-reactive protein (CRP). Method The HUVECs were primary cultured . HUVECs of the third to fifth generations were stimulated in different concentration CRP of 5,10,50 and 100mg/L and different time of 6, 12 and 24h. Then the cells were treated with Fluvastatin in different concentration of 10-7,10-6 and 10-5mol/L. The content of ICAM-1 protein was detected with ELISA, the mRNA expression of ICAM-1 was evaluated by RT-PCR. Results In the control group, HUVECs produce ICAM-1 protein and mRNA in low concentrations. In the CRP group, the content of ICAM-1 protein was increased significantly (p<0.01) and the mRNA expression of ICAM-1 was increased significantly (p <0.01). The increasing effect of ICAM-1 protein was concentration -dependent and time- dependent (p<0.01). In the Fluvastatin group, the content of ICAM-1 protein and the mRNA expression of ICAM-1 was decreased significantly (p<0.01). The inhibitory effects of fluvastatin on ICAM-1 protein was concentration -dependent (p<0.05). Conclusion Fluvastatin maybe exert the function of anti- atherosclerosis by inhibiting the expression of ICAM-1 induced by CRP in HUVECs.
