Effect of combining quercetin with 5-FU or ADR on the induction of apoptosis in AGS-cyr61 cells. (A) Synergistic effects of quercetin and 5-FU and ADR on apoptosis in AGS-cyr61 cells for 24 h. AGS-cyr61 cells were treated with 25 µM quercetin, 25 µM 5-FU, and 125 nM ADR. Treatment was given as one drug alone or as a combination of drugs. Apoptotic bodies were determined using Hoechst 33342 staining, and stained cells were visualized under a fluorescence microscope; (B) Number of apoptotic bodies. Data are the means ± standard error for one experiment performed in triplicate. * p < 0.05 compared with the control.
