摘要: 目的 研究Corilagin对氧化型低密度脂蛋白 (oxidized low density lipoprotein, OX-LDL) 损伤的巨噬细胞中C反应蛋白 (C-reactive protein, CRP) 蛋白和m RNA表达的影响.方法 体外培养小鼠单核细胞源性巨噬细胞, 复制OX-LDL诱导损伤模型;Western Blot和RT-PCR方法分别观察Corilagin对巨噬细胞中CRP蛋白和m RNA表达的影响.结果 与正常对照组比较, OX-LDL损伤模型组的CRP/β-actin和2-△△Ct值明显增加 (P<0.05) ;与模型组比较, Corilagin 3.12550μmol/L组的CRP/β-actin和2-△△Ct值明显减少 (P<0.05) .结论 Corilagin能明显下调OX-LDL损伤的巨噬细胞中CRP蛋白及m RNA的表达.Abstract: Objective To investigate the effects of Corilagin on expression of C-reactive protein (CRP) in oxidized low density lipoprotein ( OX-LDL) injured macrophage cells. Methods In vitro, mice monocyte-derived macrophages were prepared to duplicate the injury model caused by OX-LDL; Western blotting essay was used to determine the effect of Corilagin on CRP protein expression and Real time PCR assay was used to study the CRP m RNA expression, respectively. Results Compared with normal control group, the CRP/β-actin and 2-ΔΔCtvalues of OX-LDL injured model group were markedly increased (P<0.05) ;compared with the model group, Corilagin at 3.125-50 μmol/L obviously decreased the values of CRP/β-actin and 2-ΔΔCt (P<0.05) . Conclusion Corilagin could significantly down-regulate protein and m RNA expression of CRP in OX-LDL injured macrophage cells.
