CPZ induces ROS production. Immunofluorescence (red in the pictures, left) and cytofluorimetric (graphs and histograms, right) expression levels of superoxide anion (O2−) in control (CTL) or CPZ-treated T98G, U-87 MG and U-251 MG anchorage-dependent GBM cells and RPE-1 non-cancer cells. Statistical significance is referred toward the control (CTL) (*p<0.05; **p<0.01; ***p<0.001)
