MiR-145 induces OSCC cell cycle arrest. Tca8113 cells were transiently transfected with miR-145 mimics and miRNA control. After 72 h post-transfection, DNA content was measured by flow cytometry to determine cell cycle fractions. Representative flow cytometric histograms of cells transfected with miR-145 mimics and miRNA control from three independent experiments are shown in panel A. The fraction of cells in each cell cycle phase is indicated in panel B. PI, propidium iodide; *, P <0.05.
