It has been reported that endogenous retroviruses can contaminate human cell lines that have been passaged as xenotransplants in immunocompromised mice. We previously developed and described 2 human pancreatic β cell lines (EndoC-βH1 and EndoC-βH2) that were generated in this way. Here, we have shown that B10 xenotropic virus 1 (Bxv1), a xenotropic endogenous murine leukemia virus (MuLV), is pr...
We have found that 1 of 20 human tumors transplanted and passaged in nude mice was associated with a massive induction of endogenous murine leukemia virus (MuLV). Separation and growth of these viruses on various substrates indicated that both ecotropic and xenotropic MuLV were present in the induced mixture. Tryptic peptide fingerprints of the p30 and gp70 structural elements of the viruses in...
The disabling disorder known as chronic fatigue syndrome or myalgic encephalomyelitis (CFS/ME) has been linked in two independent studies to infection with xenotropic murine leukemia virus-related virus (XMRV) and polytropic murine leukemia virus (pMLV). Although the associations were not confirmed in subsequent studies by other investigators, patients continue to question the consensus of the ...
Mice of the low leukemia (BALB/cJ x A/J)F1 hybrid (CAF1) strain express B-and N-tropic infectious murine leukemia virus (MuLV) after the age of 6 mo. Initation of a protracted immunological disorder, the graft-versus-host reaction (GVHR), at 7 wk of age, accelerates the induction of both these mouse-tropic endogenous viruses, and preferentially enhances the replication of B-tropic MuLV. The ear...
In addition to the known induction of xenotropic endogenous virus in B-mitogen-stimulated murine lymphocyte cultures, distinguishable defective viruses were also induced in different mouse strains (NFS/N, 129, BALB/c). AKR cells produced xenotropic virus and also, in contrast to BALB/c, ecotropic virus. The drug bromodeoxyuridine appeared to have differential effects on virus expression, amplif...
Gross passage A murine leukemia virus (MuLV) derived from extracts of C3Hf/Bi mouse leukemias has been shown to be a virus complex consisting of ecotropic, xenotropic, and recombinant, dualtropic MuLV components. The three virus components were distinguished biochemically by differences in the molecular weights and peptide maps of their primary env gene products synthesized in infected cells in...
