Effects of Duhuo Jisheng Decoction on TNF-α-induced proliferation,apoptosis and inflammation of fibroblast-like synoviocytes in rheumatoid arthritis
目的 探究独活寄生汤含药血清对肿瘤坏死因子-α(TNF-α)诱导的类风湿性关节炎(RA)成纤维样滑膜细胞(FLS)增殖、凋亡和炎症的影响及作用机制.方法 将MH7A细胞分为正常组(10％空白血清)、模型组(10μg·L-1 TNF-α+10％空白血清)、独活寄生汤低(10 µg·L-1 TNF-α+2.5％含药血清+7.5％空白血清)、中(10 μg·L-1 TNF-α+5％含药血清+5％空白血清)、高(10μg.L-1 TNF-α+10％含药血清)剂量组共5组;MTT法筛选独活寄生汤含药血清给药浓度;EdU染色检测细胞增殖情况;免疫荧光染色检测增殖标志物Ki67表达情况;流式细胞仪检测细胞凋亡率;ELISA法检测细胞中IFN-γ、IL-4、IL-6和IL-10的含量;RT-qPCR 和 Western blot 检测 Bax、Bcl-2、caspase-3 及TLR4/MyD88/NF-κB信号通路mRNA和蛋白的表达情况.结果 与正常组比较,模型组细胞增殖水平明显上升,凋亡水平明显减弱,IFN-γ和IL-6的含量升高,IL-4和IL-10的含量减少,TLR4/MyD88/NF-κB信号通路被激活;经独活寄生汤含药血清低、中、高剂量组干预后,均能有效改善细胞异常增殖情况,增强细胞凋亡,抑制炎性反应和TLR4/MyD88/NF-κB信号通路的激活.结论 独活寄生汤含药血清能够抑制TNF-α诱导的RA-FLS异常增殖和促炎因子的分泌,增强细胞凋亡和抗炎水平,其作用机制可能与调控TLR4/MyD88/NF-κB信号通路有关.
Aim To explore the effect of serum contai-ning Duhuo Jisheng Decoction on the proliferation,ap-optosis and inflammation of fibroblast-like synoviocytes(FLS)induced by tumor necrosis factor-α(TNF-α)in rheumatoid arthritis(RA)and to reveal the under-lying mechanism.Methods The MH7A cells were divided into five groups:normal group(10％blank se-rum),model group(10 μg·L-1 TNF-α+10％blank serum),Duhuo Jisheng Decoction low(10 μg·L-1 TNF-α+2.5％drug-containing serum+7.5％blank serum),medium(10 pg·L-1 TNF-α+5％drug-con-taining serum+5％blank serum),high(10 μg·L-1 TNF-α+10％drug-containing serum)dose group.The concentration of serum containing Duhuo Jisheng Decoction was screened by MTT method.Cell prolifer-ation was detected using EdU staining.The expression of proliferation marker Ki67 was detected using immu-nofluorescence staining.The apoptosis rate was meas-ured by flow cytometry.The contents of IFN-γ,IL-4,IL-6 and IL-10 in each group were detected by ELISA.The mRNA and protein expression of Bax,Bcl-2,caspase-3 and TLR4/MyD88/NF-κB signaling pathway were detected by RT-qPCR and Western blot.Results Compared with the normal group,the cell prolifera-tion activity of the model group significantly increased,and the level of apoptosis decreased.The content of IFN-γ and IL-6 increased,and the content of IL-4 and IL-10 decreased.The TLR4/MyD88/NF-κB signaling pathway was activated.After the intervention of low,medium and high dose groups of serum containing Du-huo Jisheng Decoction,it could effectively improve the abnormal proliferation of cells and enhance apoptosis.At the same time,it inhibited the inflammatory re-sponse and the activation of TLR4/MyD88/NF-κB sig-naling pathway.Conclusions The serum containing Duhuo Jisheng Decoction can inhibit the abnormal pro-liferation of RA-FLS induced by TNF-α and the secre-tion of pro-inflammatory factors,and enhance apoptosis and anti-inflammatory levels.The mechanism may be related to the regulation of TLR4/MyD88/NF-κB sig-naling pathway.
