When gastric carcinoma cells were treated with certain concentrations of recombinant human tumor necrosis factor alpha (rhTNF-α) and 5-fluorouracil (5-FU), the proliferation of both BGC-823 and HGC-27 cells was suppressed; meanwhile, DAP3 expression was detected in the treated cell lines (77). This evidence concerns the gene DAP3 and gastric carcinoma.
