title: [Isolation and characterization of retroviruses expressed in murine osteosarcomas induced by 90Sr].
abstract: The induction of osteosarcomas with 90Sr in CF1 mice is associated with the expression of ecotropic type-C RNA viruses devoid of sarcomatogenic activity. In contrast, the FBR murine osteosarcoma virus complex, isolated from a 90 Sr-induced osteosarcoma of a X/Gf mouse [M. Finkel et al. (1)], causes the rapid appearance of osteosarcomas in newborn mice and transforms fibroblasts in vitro. The transforming capacity of FBR murine sarcoma virus has been associated as an oncogene homologous to v-fos.
