Curcumin Induces p53-Null Hepatoma Cell Line Hep3B Apoptosis through the AKT-PTEN-FOXO4 Pathway

Figure 2

Flow cytometry analysis for caspase activity after curcumin and DMSO treatments in Hep3B cells. The concentration of curcumin used in the experiments was 50 μM. -axis indicates propidium iodide (PI) intensities; -axis indicates caspase activities. The data are representative of triplicate experiments. CUR: curcumin. DMSO: dimethyl sulfoxide (solvent of curcumin).
