Figure Lengend Snippet: The influence of miR-140-3p and PPM1A on cell malignant progression and inflammatory response in RA-FLSs. RA-FLSs were transfected with miR-NC, miR-140-3p, miR-140-3p + vector, or miR-140-3p + PPM1A. A Western blot assay was performed to detect the protein expression of PPM1A. Cell proliferation ( B ), apoptosis ( C ) and cycle distribution ( D ), migration ( E ), and invasion ( F ) were measured by MTT assay, flow cytometry analysis, or transwell assay, respectively. G Western blot was carried out to examine the protein expression of Bax, Bcl-2, MMP2, and MMP9. H – J The levels of TNF-α, IL-1β, and IL-6 were analyzed by ELISA. * P < 0.05
