DIM sensitizes gastric cancer cells to the TRAIL-induced inhibition of proliferation and apoptosis by activating protein expression of death receptor 5 (DR5), CCAAT-enhancer-binding protein homologous protein (CHOP), and 78 kDa glucose-regulated protein (GRP78), which may regulate ER stress [52]. This evidence concerns the gene TNFRSF10B and gastric cancer.
