文摘研究中药白头翁主要活性成分白头翁皂苷(PULC)对类风湿性关节炎(rheumatoid arthritis,RA)模型大鼠Me CP2表达的调控作用。采用佐剂性关节炎大鼠为RA模型,原代培养RA模型大鼠滑膜成纤维细胞样滑膜细胞(FLS),Real time q PCR,Western blotting检测100 mg·kg-1PULC灌胃治疗对RA模型大鼠FLS Me CP2表达的调控作用,MTT检测PULC治疗对FLS增殖的影响,Me CP2 siRNA干扰RA模型大鼠FLS Me CP2表达后SFRP2,β-catenin表达的变化。检测发现经100mg·kg-1PULC灌胃治疗后,RA模型大鼠FLS中Me CP2表达明显降低,SFRP2表达升高,RA模型大鼠FLS增殖活力降低,Me CP2 siRNA抑制RA模型大鼠FLS Me CP2表达后,SFRP2表达明显上调,β-catenin表达明显降低。PULC可能通过抑制Me CP2表达上调SFRP2表达,抑制RA模型大鼠滑膜Wnt通路活性,抑制RA模型大鼠滑膜异常增殖。
