  • Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) induces apoptosis in a variety of transformed cell lines, but generally spares most normal cells. Transduction by an adenoviral vector expressing human TRAIL cDNA (Ad.TRAIL-GFP) resulted in both direct tumor cell killing as well as a potent bystander effect through presentation of TRAIL by transduced normal cells. Administration of Ad.TRAIL-GFP significantly prolonged survival of mice harboring either intracerebral glioblastomas or breast carcinoma-induced peritoneal carcinomatosis. Additionally, TRAIL induced prolonged transgene expression in normal tissue, presumably as a result of diminished immune-mediated destruction of vector-transduced cells. Taken together, these data suggest that vector-mediated transduction of TRAIL may represent an effective strategy for cancer gene therapy.
