- AB Characterization of the SRS murine retrovirus complex, derived from the
- TSZ system of murine leukemia developed in China, was carried out. The
- initial stock contained XC+, NB-tropic virus (and possibly other
- viruses), and induced several neoplastic diseases in neonatally
- inoculated NIH Swiss mice: erythroid leukemia, myeloid leukemia (acute
- myeloblastic leukemia), and lymphoblastic lymphoma (both B- and
- T-lymphoid). In addition, approximately 30% of inoculated animals
- developed central nervous system disease--hindlimb paralysis or
- semilateral paralysis. Rescue of virus from the spleen of an animal with
- combined erythroid/myeloid leukemia, followed by endpoint dilution gave
- two stocks: 19-6 (XC+, NB-tropic) and 19-7 (XC-, NB-tropic). Both stocks
- induced erythroid and myeloid leukemia, and 19-6 induced CNS symptoms as
- well. Southern blot analysis indicated that the predominant viruses from
- the 19-6 and the 19-7 cultures were related, but different in the env
- region. An infectious virus molecular clone of provirus from 19-6 cells
- was obtained. The resulting cloned virus [SRS 19-6 murine leukemia virus
- (MuLV)] induced four kinds of leukemia: erythroid, myeloid, B-lymphoma,
- and T-lymphoma; in many cases, more than one tumor type was identified
- in the same animal. Such a broad spectrum of leukemias induced by a
- cloned MuLV is unusual. Flaccid hindlimb paralysis induced by SRS 19-6
- MuLV could be attributed to meningeal B-lymphoma. Immunofluorescent
- staining with a panel of env-specific monoclonal antibodies confirmed
- that the 19-6 and 19-7 viral stocks contained different viruses, which
- differed from previously characterized MuLVs. The viruses of the SRS
- complex may provide interesting reagents for investigations of
- MuLV-induced disease.
