TNFSF10 and gastric cancer: In order to investigate the role of DNER in the sensitivity of gastric cancer cells to various chemotherapeutic drugs and the tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), cell viability of the siDNER-transfected cells treated with adriamycin, 5-fluorouracil (5-FU), cisplatin, TRAIL, and oxaliplatin was compared with the siSC-transfected cells.
