Galuteolin suppressed cell viability and induced cell apoptosis in RA-FLS cells. a CCK-8 assay was utilized to measure RA-FLS cell proliferation in TNF-α-induced cells after different concentrations of Galu treatments. b TUNEL staining was conducted to detect cell apoptosis in RA-FLS cells in the four groups. c Western blot analyses of Bax, Bcl-2 cleaved-caspase-3, and caspase-3 protein expression in RA-FLS cells with indicated treatments. *p < 0.05 and ***p < 0.001 vs. control; ^#p < 0.05, ^##p < 0.01, and ^###p < 0.001 vs. TNF-α
