title: Inhibition of chemically induced carcinogenesis of canine cells in vitro by infection with mouse xenotropic type C virus.
abstract: C57L mouse xenotropic type C virus infection inhibited N-methyl-N'-nitro-N-nitrosoguanidine (MNNG)-induced in vitro transformation of embryo cells from inbred beagles. Treatment with MNNG induced in vitro neoplastic transformation in uninfected canine cells but not in C57L virus-infected canine cells; the C57L virus-infected canine cells not treated with MNNG also remained untransformed. In this dog cell system, preinfection with a C57L mouse xenotropic type C virus inhibited in vitro neoplastic transformation induced by MNNG.
