ATF3 facilitating pro-inflammatory cytokine secretion in rheumatoid arthritis fibroblast-like synoviocyte (RA-FLS) and MH7A. (A and C) ELISA assays showed that IL-1β, IL-6, and IL-8 in the Sh-ATF3 group were lower than those in the Sh-Ctrl group with or without TNF-α stimulation, which in the ATF3-OE group were higher than those in the Ctrl-OE group (mean ± SD, n = 3). (B and D) Similarly, qRT-PCR assays revealed that IL-1β, IL-6, and IL-8 in the Sh-ATF3 group were lower than those in the Sh-Ctrl group with or without TNF-α stimulation, which in the ATF3-OE group were higher than those in the Ctrl-OE group (mean ± SD, n = 3). * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001.
