Curcumin Synergistically Enhances the Cytotoxicity of Arsenic Trioxide in U266 Cells by Increasing Arsenic Uptake

Figure 1

Inhibitory effects of ATO on U266 cells. (a, b) The inhibition rates of U266 cells treated with different concentrations of ATO (0, 1, 2.5, 5, and 10 μmol/L) for 24/48 h. indicates for ATO treatment after 48 h in U266 cells compared with 24 h and # indicates . (c, d) The apoptosis rates of U266 cells treated with different concentrations of ATO (0, 2.5, and 5 μmol/L) for 48 h. indicates for the ATO 2.5 treatment group compared with the untreated group; indicates for the ATO 5 treatment group compared with the untreated group.
