Abstract excerpt
BACKGROUND: Fibroblast-like synoviocytes (FLS) are central mediators of synovial inflammation and joint destruction in rheumatoid arthritis (RA). While tumor necrosis factor-α (TNFα) is known to activate FLS, the upstream regulators that connect inflammatory stimulation with sustained stromal pathogenicity remain poorly defined. The LIN28A‒let-7 microRNA axis regulates proliferation and invasiveness in diverse...
