Based on the results of qRT-PCR and Western blot assay (Figure 9A,B), we found that expression of miR-101-3p in RA-FLSs was increased and the expression of PTGS2 decreased in the miR-101-3p mimics group compared with the mimic-NC group (all P<0.05). The gene discussed is PTGS2; the disease is rheumatoid arthritis.
