Stimulation of the human synovial sarcoma cell line SW982 with IL-1β inhibits the expression of miR-10a, leading to the up-regulation of its target gene, T-box transcription factor 5 (TBX5), which induces the proliferation of synoviocytes and suppression of synoviocyte apoptosis in RA [143]. The gene discussed is TBX5; the disease is synovial sarcoma.
