ABSTRACT
<p><b>OBJECTIVE</b>To study the effect of pulchinenoside (PULC) in modulating SFRP2 expression in fibroblast-like synoviocytes (FLS) of rheumatoid arthritis (RA) model rats.</p><p><b>METHOD</b>The effect of PULC in treating RA rats was evaluated by rat arthritis score and paw swelling score. The inhibitory effect of PULC on FLS proliferation was detected by MTT reagent. The effects of PULC gavage treatment in modulating gene expression of FLS SFRP2, critical gene beta-catenin of Wnt pathway and downstream effector genes C-myc of of Wnt pathway were detected by RT-PCR and Western blotting.</p><p><b>RESULT</b>PULC had a significant effect in treating RA rats and that SFRP2 expression was down-regulated in FLS. After PULC gavage treatment, FLS SFRP2 expression was obviously up-regulated, whereas beta-catenin and C-myc gene expressions were significantly down-regulated.</p><p><b>CONCLUSION</b>PULC can inhibit abnormal proliferation of synovial membrane by modulating Wnt pathway of RA rats.</p>
