Resveratrol (trans-3,4'-trihydroxystilbene), a natural phytoalexin, possesses anti-inflammatory, anti-proliferative, and immunomodulatory properties and has the potential for treating inflammatory disorders. The present study was designed to investigate the effects of resveratrol on TNF-α-induced inflammatory cytokines production of IL-1β and MMP3 in Rheumatoid arthritis (RA) Fibroblast-like synoviocytes (FLS) and further to explore the role of PI3K/Akt signaling pathway by which resveratrol modulates those cytokines production. The levels of IL-1β, MMP-3 in cultural supernatants among groups were measured by enzyme-linked immunosorbent assay. Messenger RNA expression of IL-1β and MMP-3 in RA FLS was analyzed using a reverse transcription-polymerase chain reaction. Western blot analysis was used to detect proteins expression in RA FLS intervened by resveratrol. Resveratrol inhibited both mRNA and proteins expressions of IL-1β and MMP-3 on RA FLS in a dose-dependent manner. Resveratrol also decreased significantly the expression of phosphorylated Akt dose dependently. Activation of PI3K/Akt signaling pathway exists in TNF-α-induced production of IL-1β and MMP3 on RA FLS, which is hampered by PI3K inhibitor LY294002. Immunofluorescence staining showed that TNF-α alone increased the production of P-Akt, whereas LY294002 and 50 μM resveratrol suppressed the TNF-α-stimulated expression of P-Akt. Resveratrol attenuates TNF-α-induced production of IL-1β and MMP-3 via inhibition of PI3K-Akt signaling pathway in RA FLS, suggesting that resveratrol plays an anti-inflammatory role and might have beneficial effects in preventing and treating RA.
