Expression of miRNAs in synovium and FLSs treated with pro-inflammatory cytokines. Expression of miR-486-5p, miR-708-5p, miR-186-5p, and miR-145a-5p are evaluated by qPCR analysis using whole synovial RNA samples (n =2 pools each with technical replicates, error bars are SD) (left). FLS are treated with TNF (10 ng/mL), IL-17 (50 ng/mL), IL-1 (10 ng/mL) for 3 days (right). Relative expression of miRNA was examined by qPCR (error bars are SD). NA or control (untreated) =1. miRNAs are normalized to U6. FLS =fibroblast-like synovial cell; NA =nonarthritic.
