title: Oncogenicity in marmosets of HL-23V, a type C oncornavirus isolated from human leukemic cells, and comparison with simian sarcoma virus type 1 (SSV-1/SSAV-1).
abstract: Type C virus produced by dog thymus cells (A7573) that were infected with virus (HL-23V), isolated from cultured leukocytes of an acute myelogenous leukemia patient, transformed marmoset and horse cells in vitro and induced virus-producing fibromas in marmosets. The tumors and transformed foci were indistinguishable morphologically from those induced by simian sarcoma virus, type 1 (SSV-1/SSAV-1). HL-23V was indistinguishable from SSV-1/SSAV-1 by immunofluorescence and neutralization tests, and the nontransforming virus associated with HL-23V completely inhibited SSV-1 focus induction in interference tests. Cell cultures established from a marmoset fibroma produced transforming and nontransforming virus biologically and antigenically indistinguishable from HL-23V and SSV-1/SSAV-1.
