Effects of miR-203 expression on proliferation, migration and invasion of renal cancer cells. A. Over-expression of miR-203 by transfection with miR-203 mimics in 786-O cells. B. Down-regulation of miR-203 by transfection with miR-203 inhibitor in 786-O cells. C,D. CCK-8 assay was performed to analyze the effect of miR-203 on cell proliferation of 786-O cells. E-H. Transwell migration and invasion assays were utilized to analyze the effect of miR-203 on cell migration(E,F) and invasion(G,H) of 786-O cells.* P <0.05.
