Fibroblast-like synoviocytes (FLS), one of the main cell types of the rheumatoid arthritis (RA) synovium, possess phenotypic and molecular characteristics of transformed cells. JQ1, an inhibitor of the bromodomain and extra terminal domain family that includes BRD2, BRD3, BRD4, and BRDt, has shown efficacy in models of arthritis. We demonstrate that the active isomer of JQ1 but not its inactive isomer inhibits IL-1β-induced RA-FLS activation and proliferation. To understand the mechanism of JQ1 action, we subjected JQ1-treated RA-FLS
