Effects of miR-27a on the expression of migration and invasion-related proteins in RA-FLS. RA-FLS were transfected with miR-27a mimic or miR-27a inhibitor. (A) The protein and mRNA expression of MMP2, MMP9, and MMP13 in RA-FLS was detected by western blot and qRT-PCR assay. (B) The protein and mRNA expression of Rac1, Cdc42, and RhoA in RA-FLS was detected by western blot and qRT-PCR assay. *p < 0.05, versus control mimic group. #p < 0.05, versus control inhibitor group.
