Effects of ZnO-NPs on cell cycle progression and apoptosis in human GSCC cells. (a) Ca9-22 cells were treated with ZnO-NPs (10–20 µg/mL) for 24 h, and subsequently analyzed by propidium iodide (PI) staining to determine the cell cycle distribution. Lower panel, quantitative data were based on histograms. Ca9-22 (b) and OECM-1 (c) cells were treated with the indicated concentrations of ZnO-NPs for 24 h to determine apoptosis using a Cell Death ELISA^PLUS kit. Data are expressed as the mean ± SEM of at least three independent experiments. * p < 0.05 compared to the control group.
