COE treatment induced cytoskeletal collapse. The organization of the filamentous actin (F-actin, red fluorescence), the distribution of vinculin (green fluorescence), and the nuclear (blue fluorescence) were observed using confocal fluorescence microscopy (magnification, ×1000; scale bar, 10 μm).a U251 and U87 cells of control group. b 80 μg/mL COE treated U251 cells
