Dimethyl celecoxib sensitizes gastric cancer cells to ABT-737 via AIF nuclear translocation.

ABSTRACT: Gastric cancer is the fourth most common cancer in the world. The clinical applications of both chemotherapy and targeted drugs are limited because of the complexity of gastric cancer. In this study, sulforhodamine B, colony formation assay, 4',6-diamidino-2-phenylindole (DAPI) stain, flow cytometry were used to determine the in vitro cytotoxicity, apoptosis and mitochondrial membrane potential of gastric cancer AGS and HGC-27 cells before and after treatment. Real-time PCR and Western blot were used to analyse the mRNA transcription and protein expression respectively. Confocal microscopy was used to determine the localization of target protein within the cells. Treatment with the combination of ABT-737 and 2,5-dimethyl-celecoxib (DMC) showed strong synergistic effect in both AGS and HGC-
