A. Cytotoxicity of arsenic trioxide to PLHC-1”. Cells were treated with an indicated concentration of As2O3 (0–500 μM) for 24 h to determine the acute cytotoxicity dose (IC50 of As2O3). All values are represented as percentage of (n = 3) ± SEM. B MTT assay to determine cell proliferation at various time points against various concentrations of As2O3. All values are represented as percentage of (n = 3) ± SEM. Asterisks indicate significant different from control (*p < 0.05)
