Anti-tumor capacity of Ad-TRAIL-MRE-1-133-218 on bladder cancer cells with no significant cytotoxicity to normal cells. (a) Apoptosis was detected in the indicated cells by FACS analysis on Annexin V expression. Means ± SEM of three independent experiments were shown. (b) Cleavages of caspase 3, caspase 8 and PARP were determined by immunoblotting assay. Arrows indicated the cleaved fragments of these proteins. GAPDH was selected as endogenous reference. (c) Viability of different cells was determined after the indicated adenoviruses were applied. The absorptive values of cells without adenovirus infection were used as standards. Means ± SEM of three independent experiments were shown.
