GZMA and rheumatoid arthritis: Among the target miRNAs of GZMA, PRC1, and TTK, the expression of the following miRNAs was downregulated in RA: miR-129-5p (in RA synovial tissue and synovial fibroblasts), miR-132-3p (in RA synovial fibroblasts), miR-212-3p (in RA synovial tissue and synovial fibroblasts), and miR-25-3p (in peripheral blood mononuclear cells) [37–40].
