Abstract
Tumor necrosis factor-alpha receptor cDNA (TNFR-1 or TNFR-2) was inserted into a retrovirus derived vector. Recombinant vector was transfected into packaging cell line. The transfectants producing high titer of virus containing TNFR-1 or TNFR-2 cDNA were obtained. Human stomach cancer cells that poorly expressed TNFR-1 or TNFR-2 were infected with this virus as an in vitro model experiment of gene therapy. The stomach cancer cells that were infected with recombinant virus expressed TNFR-1 or TNFR-2 and were effectively killed by recombinant TNF.
