目的:研究金雀异黄素(Gen)对类风湿关节炎(RA)患者间充质干细胞(MSCs)中的核因子κB 受体活化因子(RANK)、核因子κB 受体活化因子配体(RANKL)和骨保护素(OPG)系统的影响及其机制。方法分离培养正常人与 RA 患者的骨髓 MSCs(BM-MSCs),分为空白对照组、Gen 处理组、雌二醇(E2)处理组和 Gen +雌激素受体拮抗剂(ICI182780)组,采用 Western blot 法检测 BM-MSCs 中 RANK、RANKL、OPG 的表达;采用免疫荧光法检测雌激素受体α(ERα)细胞内分布情况。结果Western blot 结果显示:与正常人 BM-MSCs 相比,RA 患者 BM-MSCs 中的 RANK 的蛋白表达水平明显升高,OPG 的蛋白表达水平明显降低,RANKL/OPG 比值升高;Gen 显著上调 RA 患者 BM-MSCs 中 OPG 表达,对 RANK、RANKL 表达无明显影响,从而降低了 RANKL/OPG 比值,与 E2作用类似。免疫荧光结果显示:Gen 能促进 RA 患者的 BM-MSCs 中 ERα入核。结论Gen 可能通过活化雌激素受体介导的相关信号通路,调控 RA 患者 BM-MSCs 中 RANKL /OPG 的表达,从而调节破骨细胞分化及成骨细胞分化,抑制 RA 关节破坏和促进受损关节的修复。
目的:研究金雀異黃素(Gen)對類風濕關節炎(RA)患者間充質榦細胞(MSCs)中的覈因子κB 受體活化因子(RANK)、覈因子κB 受體活化因子配體(RANKL)和骨保護素(OPG)繫統的影響及其機製。方法分離培養正常人與 RA 患者的骨髓 MSCs(BM-MSCs),分為空白對照組、Gen 處理組、雌二醇(E2)處理組和 Gen +雌激素受體拮抗劑(ICI182780)組,採用 Western blot 法檢測 BM-MSCs 中 RANK、RANKL、OPG 的錶達;採用免疫熒光法檢測雌激素受體α(ERα)細胞內分佈情況。結果Western blot 結果顯示:與正常人 BM-MSCs 相比,RA 患者 BM-MSCs 中的 RANK 的蛋白錶達水平明顯升高,OPG 的蛋白錶達水平明顯降低,RANKL/OPG 比值升高;Gen 顯著上調 RA 患者 BM-MSCs 中 OPG 錶達,對 RANK、RANKL 錶達無明顯影響,從而降低瞭 RANKL/OPG 比值,與 E2作用類似。免疫熒光結果顯示:Gen 能促進 RA 患者的 BM-MSCs 中 ERα入覈。結論Gen 可能通過活化雌激素受體介導的相關信號通路,調控 RA 患者 BM-MSCs 中 RANKL /OPG 的錶達,從而調節破骨細胞分化及成骨細胞分化,抑製 RA 關節破壞和促進受損關節的脩複。

Objective To explore the mechanism and effect of genistein (Gen)on receptor activator of nuclear factor kappa B (RANK),RANK ligand (RANKL)and osteoprotegerin (OPG)of mesenchymal stem cells (MSCs)in rheumatoid arthritis (RA)patients.Methods BM-MSCs isolated and cultured from normal adults and RA patients were divided into normal control group,Gen-treated group,E2-treated group and Gen +estrogen receptor antagonist group.Western blot was used to de-tect expression of RANK,RANKL and OPG,and immunofluorescence was used to detect the distribu-tion of estrogen receptorα(ERα)in BM-MSCs.Results According to result of Western blot,com-pared with normal adults,the expression of RANK in BM-MSCs from RA patients was higher,and the expression of OPG was lower,the RANKL/OPG ratio was higher.Similar to E2 treated group,Gen was able to significantly up-regulate the expression of OPG but show no effects on the expression of RANK, RANKL,which resulted in significant decrease of the RANKL/OPG ratio.The results from immunoflu-orescence showed that Gen could facilitate ERαtransferring into the nucleus.Conclusion Gen can regulate the expression and balance of RANKL/OPG in BM-MSCs in RA patients,and further modu-late osteoclast and osteoblast differentiation,inhibit RA joint destruction and promote recovery of dam-aged joints through activating estrogen receptor mediated signal pathway.
