摘要: 采用实时荧光定量PCR法分析了牛磺鹅去氧胆酸(taurochenodeoxycholic acid,TCDCA)对佐剂性关节炎模型(adjuvant arthritis,AA)大鼠成纤维滑膜细胞(fibroblast-like synoviocytes,FLS)中由糖皮质激素受体(glucocorticoid receptor,GR)介导的热休克蛋白90基因(heat shock protein 90 gene,HSP90)mRNA表达的影响。结果表明,TCDCA可以极显著性(P〈0.01)下调FLS细胞内HSP 90 mRNA的表达,同时加入GR的特异性抑制剂RU486后可抑制TCDCA对HSP 90 mRNA的作用。由此证明了TCDCA是通过GR受体发挥抗炎和免疫调节作用的。

Abstract: The effect of taurochenodeoxycholic acid (TCDCA) on HSP90 mRNA expression mediated by glucocorticoid receptor (GR) in fibroblast-like synoviocytes (FLS) in rats with adjuvant arthritis (AA) was assessed by real-time quantitative PCR assay. The results showed that TCDCA extremely significantly down-regulated the HSP90 mRNA expression in FLS cells (P〈 0.01 ). In addition, the effect of TCDCA on HSP90 mRNA expression could be inhibited by RU486, a specific inhibitor against GR. It was indicated that TCDCA exerted anti-inflammatory and immunoregulative action via GR.
