ABSTRACT
The purpose of this study is to investigate the effect of TSAHC [4'-(p-toluenesulfonylamido)-4-hydroxychalcone] in K/BxN serum transfer arthritis model and fibroblast-like synoviocytes of rheumatoid arthritis (RA-FLS). In in vivo experiments, TSAHC attenuated the incidence and severity of arthritis in comparison with the vehicle group. Histological findings showed that TSAHC decreased the inflammation, bone erosion, cartilage damage, and osteoclasts activity in the ankle. Furthermore, we confirmed by biochemical analysis that the observations were associated with the decreased expression of proinflammatory cytokines, matrix metalloproteinases (MMPs), and RANKL in serum and ankle. In in vitro experiments, TSAHC induced apoptosis, while it significantly suppressed tumor necrosis factor-α (TNF-α)-induced cell proliferation in RA-FLS. Moreover, TSAHC inhibited mRNA expression of TNF-α-induced interleukin (IL)-6, MMP-1, MMP-3, and MMP-13. Evaluation of signaling events showed that TSAHC inhibited the translocation and transcriptional activity of nuclear factor-kappa B (NF-κB) by regulating phosphorylated-IκB-α (p-IκB-α) and IκB-α in TNF-α-induced RA-FLS. Our results suggest that TSAHC inhibits experimental arthritis in mice and suppresses TNF-α-induced RA-FLS activities via NF-κB pathway. Therefore, TSAHC may have therapeutic potential for the treatment of RA.
