摘要
目的观察蜂毒注射液对人类风湿关节炎成纤维样滑膜细胞(类风湿关节炎-FLS)B淋巴细胞瘤-2基因(Bcl-2)、Bcl-2相关X蛋白(Bax)m RNA和蛋白的影响,探讨蜂毒注射液治疗类风湿关节炎的作用机制。方法滑膜组织取自行关节置换或关节镜手术的4名活动期类风湿关节炎患者,分离出FLS并原代培养,逆转录–聚合酶链反应(RT-PCR)观察Bax、Bcl-2 mRNA表达的变化,酶联免疫吸附测定(ELISA)法检测Bax、Bcl-2蛋白水平的变化。结果与对照组比较,蜂毒注射液4、8、16 mg/L组能促进Bax mRNA表达(P<0.05),蜂毒注射液8、16 mg/L组抑制Bcl-2 mRNA表达(P<0.05、0.01);蜂毒注射液4、8、16 mg/L组提高Bax蛋白水平,降低Bcl-2蛋白水平(P<0.05、0.01),且有一定的剂量相关性。结论蜂毒注射液可能通过抑制Bcl-2蛋白、促进Bax蛋白的表达,达到促进类风湿关节炎-FLS凋亡的作用。
Objective To observe the effect of Apistoxin Injection on B-lymphoma-2 gene(Bcl-2), Bcl-2-related X protein(Bax) m RNA and protein in human rheumatoid arthritis fibroblast like synoviocytes(RA-FLS), and to explore the mechanism of Apistoxin Injection in treatment of rheumatoid arthritis. Methods FLS was isolated from synovium of 4 active RA patients who underwent arthroscopic surgery or joint replacement. The expression of Bax and Bcl-2 mRNA was observed by Real time-PCR(RT-PCR) method, and the contents of Bax and Bcl-2 protein were detected by ELISA method. Results Compared with the control group, Apistoxin Injection 4, 8, and 16 mg/L groups could promote the expression of Bax mRNA(P<0.05), and Apistoxin Injection 8 and 16 mg/L groups could inhibit the expression of Bcl-2 mRNA(P<0.05, 0.01). Apistoxin Injection 4, 8, and 16 mg/L groups could increase the content of Bax protein and decrease the content of Bcl-2 protein(P<0.05, 0.01), which was dose-dependent. Conclusion Apistoxin injection may promote the apoptosis of RA-FLS by inhibiting the expression of Bcl-2 protein and promoting the expression of Bax protein.
