Curcumin induces cell apoptosis in EBV-positive NPC cells. (a) Effect of curcumin on cell apoptosis. HONE1 and HK1-EBV cells were treated with DMSO (vehicle control) or curcumin at indicated concentrations, for 24 h. Cellular apoptosis was analyzed by flow cytometry. (b) HONE1 and HK1-EBV cells were treated with DMSO (vehicle control) or curcumin at indicated concentrations, for 48 h, and the related protein expression levels were determined by western blot analysis.
