Effects of different concentrations of lapachol on apoptosis and DNA damage of C6 cells. a Hoechst 33258 staining for C6 glioma cells after being treated with control (a), 1 μM lapachol (b), 5 μM lapachol (c), and 10 μM lapachol (d). riginal magnification: ×200. b Annexin V-FITC/PI staining for apoptosis rates of cells after being treated with control (a), 1 μM lapachol (b), 5 μM lapachol (c), and 10 μM lapachol (d). c Comet assay result of cells after being treated with control (a), 1 μM lapachol (b), 5 μM lapachol (c), and 10 μM lapachol (d). Original magnification: ×200. d Tail intensity of C6 cells in the comet assay. Mean ± SD of three independent experiments. ^* P < 0.05 compared with the control
