摘要：探讨獐牙菜苦苷、龙胆苦苷和獐牙菜苷对类风湿关节炎成纤维样滑膜细胞(rheumatoid arthritis fibroblast-like synoviocytes,RA-FLSs)及B淋巴细胞瘤-2(B-cell lymphoma-2,Bcl-2)的影响并讨论其作用机制。通过ZINC数据库和RCSB PDB数据库查询獐牙菜苦苷、龙胆苦苷和獐牙菜苷的三维化学成分结构和Bcl-2的蛋白靶点三维结构;借助AutoDock Mgltools 1.5.6软件、AutoDock Vina 1.1.2软件和pyMOL 2.2.0软件将獐牙菜苦苷、龙胆苦苷和獐牙菜苷的三维化学成分结构与Bcl-2(1GJH)靶点蛋白三维结构进行对接并分析;借助Annexin V-FITC细胞凋亡试剂盒检测给药后各组RA-FLSs的凋亡情况;借助Western blot法检测给药后各组RA-FLSs的Bcl-2蛋白表达情况;借助RT-PCR技术检测给药后各组RA-FLSs的Bcl-2 mRNA表达情况。各给药组的成分结构与Bcl-2(1GJH)的结合活性较好,獐牙菜苦苷的结合能为-6.9 kcal·mol^(-1),龙胆苦苷的结合能为-6.7 kcal·mol^(-1),獐牙菜苷的结合能为-6.4 kcal·mol^(-1);龙胆苦苷组的促细胞凋亡作用最强(P<0.01),獐牙菜苷组次之,獐牙菜苦苷组最次;龙胆苦苷组的Bcl-2蛋白表达水平最低,抑制Bcl-2蛋白表达作用最强(P<0.01),獐牙菜苦苷组和獐牙菜苷组间比较无差异,作用相近;各给药组较空白组的Bcl-2 mRNA基因表达水平显示出不同程度降低(P<0.01,P<0.05),且作用相近。龙胆苦苷可以促进RA-FLSs凋亡,降低RA-FLSs的Bcl-2蛋白表达水平和Bcl-2 mRNA的基因表达水平,进而缓解因RA-FLSs的凋亡不足与异常增殖引起的病症。
The aim of this paper was to discuss the effect of swertiamarin,gentiopicrin and sweroside on rheumatoid arthritis fibroblast-like synoviocytes(RA-FLSs)and B-cell lymphoma-2(Bcl-2)and their mechanisms.ZINC database and RCSB PDB database were retrieved for 3 D chemical structures of swertiamarin,gentiopicrin and sweroside and 3 D target protein structures.AutoDock Mgltools 1.5.6,AutoDockVina 1.1.2 and pyMOL 2.2.0 were applied for molecular docking to analyze the relationship between Bcl-2(1 GJH)target protein and important ingredients.The cell apoptosis of RA-FLSs was tested by Annexin V-FITC.The Bcl-2 protein expression of RA-FLSs treated with different ingredients was tested by Western blot.The Bcl-2 mRNA expression of RA-FLSs treated with different ingredients was tested by RT-PCR.Swertiamarin,gentiopicrin and sweroside were docked well with Bcl-2(1 GJH).The binding energy of swertiamarin was-6.9 kcal·mol^(-1),the binding energy of gentiopicrin was-6.7 kcal·mol^(-1)and the binding energy of sweroside was-6.4 kcal·mol^(-1).Compared with the blank group,the Bcl-2 protein expression of each group were reduced,while that of the gentiopicrin group was the highest(P<0.01).Compared with the blank group,the Bcl-2 mRNA expression of each groups were reduced.Gentiopicrin can reduce the Bcl-2 protein expression and the Bcl-2 mRNA expression,so as to promote the RA-FLSs apoptosis.
