  1. Note: ※ Values represent the mean ± SD; a There were significant differences in the protein expression of cytochrome C, caspase-9 and caspase-3 between each treatment group compared with the control group, P <0.05. b Compared with the 5-FU group, the protein expression of cytochrome C, caspase-9 and caspase-3 was significantly higher in the 5-FU + celecoxib group, P <0.05. C Compared with the celecoxib group, the protein expression of cytochrome C, caspase-9 and caspase-3 was also significantly higher in the 5-FU + celecoxib group, P <0.05.
