Lymphomagenicity of recombinant mink cell focus-inducing murine leukemia viruses
Recombinant mink cell focus-inducing (MCF) murine leukemic viruses, as well as ecotropic and xenotropic viruses, were tested for ability to accelerate or cause development of lymphoma in AKR and other strains of mice. Of the three classes of virus isolated from AKR, only the MCF viruses were able to accelerate development of AKR lymphoma. This fully supports the idea that the MCF viruses are th...
متن کاملMechanism of leukemogenesis induced by mink cell focus-forming murine leukemia viruses.
The Friend or Moloney mink cell focus-forming (MCF) virus encodes a recombinant-type envelope glycoprotein, gp70, that is closely related to the membrane glycoprotein, gp55, of Friend spleen focus-forming virus (SFFV). We have shown previously that gp55 has the ability to activate cell growth by binding to the cellular receptor for erythropoietin. Here we show that gp70 encoded by either the Fr...
متن کاملMink cell focus-forming murine leukemia virus killing of mink cells involves apoptosis and superinfection.
Induction of apoptosis by different types of pathogenic retroviruses is an important step in disease development. We have observed that infection of thymic lymphocytes by the mink cell focus-forming murine leukemia virus (MCF MLV) during the preleukemic period resulted in an enhancement of apoptosis of these cells. To further study the ability of MCF MLVs to induce apoptosis and the role of thi...
متن کاملA mouse gene on chromosome 5 that restricts infectivity of mink cell focus-forming recombinant murine leukemia viruses
DBA/1, DBA/2, CBA/N, and CBA/Ca mice carry a gene which specifically restricts infectivity of mink cell focus-forming (MCF) murine leukemia viruses. The gene, designated Rmcfr, is dominant or semidominant and maps to chromosome 5; it is closely linked to the morphologic marker gene Hm. The Rmcf gene may be of much use as a means of determining the role of MCF viruses in various forms of leukemo...
متن کاملCell-surface antigens associated with recombinant mink cell focus- inducing murine leukemia viruses
Distinct type-specific antigens were detected on cells infected with cloned mink cell focus-inducing (MCF) murine leukemia viruses by means of cell surface immunofluorescence absorption assays with rabbit antisera raised against naturally-occurring AKR MCF viruses. The MCF type-specific antibodies were present in high titer and not absorbable by cells infected with ecotropic, xenotropic, or wil...
