VACCINIA VIRUS MEDIATED p53 GENE THERAPY FOR BLADDER CANCER IN AN ORTHOTOPIC MURINE MODEL

Abstract

To our knowledge we report for the first time that recombinant vaccinia virus expressing human p53 can induce the death of MB-49 tumor cells in vivo, not only through the lytic effect of the virus, but also through expression of the death inducing p53 transgene. Further studies are needed to shed light on the mechanisms of rVV-TK-53 mediated tumor apoptosis and the antitumor immune response.
