For instance, miR-103a-3p mediates TNF-α-induced synovial inflammation and bone erosion by targeting MAP3K7 and DKK1 50, while miR-548aj-3p and miR-3127-3p attenuate RANKL-driven expression of pro-inflammatory cytokines and matrix-degrading enzymes in both osteoarthritis and RA 51. Here, MAP3K7 is linked to rheumatoid arthritis.
