Upregulation of miR-940 expression promoted apoptosis and suppressed invasion in glioma cells. A, B. Apoptosis of U87 and U118 cells was examined by TUNEL assay (three repeated experiments with three samples were experiment). The nuclei labelled with red fluorescence represent early apoptotic cells. C, D. Flow cytometry was used to detect the proportion of apoptotic cells (three repeated experiments with three samples per experiment). E, F. Transwell assays showed the cell invasion ability of U87 and U118 cells. Magnification: 200×. All data are expressed as the mean ± s.e.m.
