Effects of miR-133a on glioma cell proliferation and metastasis. (A) Relative expression levels of miR-133a and XIST in glioma cells following transfection with miR-133a mimics or inhibitor. (B) Cell viability following transfection with miR-133a mimics or inhibitor assessed by MTT assay. (C) Migration (magnification, ×16) and (D) invasion (magnification, ×100) of cell lines detected by scratch-wound healing and Transwell migration assays, respectively. (E) Western blotting showing the expression of E-cadherin, N-cadherin, α-catenin and vimentin in glioma cells following transfection with miR-133a inhibitor or mimics. (F) Expression level of SOX4 transcription factor. n=3. *P<0.05, **P<0.01 and ***P<0.001. miR, microRNA; XIST, X-inactive specific transcript; SOX, SRY-box; NC, negative control; OD, optical density.
