Acacetin inhibits expression of matrix metalloproteinases via a MAPK‐dependent mechanism in fibroblast‐like synoviocytes

It is well known that rheumatoid arthritis (RA) is an autoimmune joint disease in which fibroblast‐like synoviocytes (FLSs) play a pivotal role. In this study, we investigated the anti‐arthritic properties of acacetin in FLSs. The expression of matrix metalloproteinase (MMP)‐1, MMP‐3 and MMP‐13 were...

Zusammenfassung:It is well known that rheumatoid arthritis (RA) is an autoimmune joint disease in which fibroblast‐like synoviocytes (FLSs) play a pivotal role. In this study, we investigated the anti‐arthritic properties of acacetin in FLSs. The expression of matrix metalloproteinase (MMP)‐1, MMP‐3 and MMP‐13 were investigated by quantitative RT‐PCR and western blot at gene and protein levels. At the same time, the phosphorylation of mitogen‐activated protein kinases (MAPK) was investigated. The DNA‐binding activity of NF‐κB was investigated by electrophoretic mobility shift assay. We found that acacetin inhibits p38 and JNK phosphorylation and reduces MMP‐1, MMP‐3 and MMP‐13 expression in interleukin‐1β‐induced FLSs. Our results suggest that acacetin has antiarthritic effects in FLSs. Thus, acacetin should be further studied for the treatment of arthritis.
