Circulating soluble tumor antigens were detected in the serum of tumor-bearing rats. Sublethally irradiated W/Fu rats inoculated with syngeneic C58(NT)D Gross virus-induced lymphoma served as the source of tumor antigens. Soluble antigens were assessed by specific inhibition of the complement-mediated cytotoxicity of isogenic W/Fu anti-C58(NT)D antibodies against 51Cr tumor target cells. With a...
Development of polioencephalomyelitis in mice infected with lactate dehydrogenase-elevating virus (LDV) requires expression of N-tropic ecotropic MuLV retroviruses. 129/Sv mice are resistant to N-tropic MuLV expression and therefore do not develop LDV-induced polioencephalomyelitis. The Fv1 gene determines the susceptibility to retrovirus replication. We sequenced the open reading frame of the ...
By inhibiting techniques using indirect immunofluorescence tests and indirect immunoelectron microscopy, the G(Gross) soluble antigens (GSA) in the body fluids of AKR and C58 mice, which have a high incidence of spontaneous leukemia, were classified according to the known specificity of G antigens in the murine Gross leukemia system. GSA existing in the plasma of nonleukemic and leukemic AKR mi...
Immunosuppression, occurring naturally with aging, or experimentally after cyclophosphamide treatment or irradiation, is required for the development in C58 mice infected with lactate dehydrogenase-elevating virus (LDV) of a severe polioencephalomyelitis that is caused by viral destruction of anterior horn neurons. Here it is shown that depletion of T helper lymphocytes by administration of an ...
The sensitivity of A/HeJ, AKR/J, C3H/HeJ, C57BL/6J, C58/J, and DBA/2J male mice to single i.p. injections of 7,12dimethylbenz[a]anthracene (DMBA) was investigated. The drug was administered in a single dose of 0.75 to 3 mg per mouse and animals were sacrificed 5-20 days after injection. The AKR mice were least affected by DMBA. Acute ]>eritoneal inflamma tion accompanied by accumulation of an e...
Two groups independently sequenced the Agrobacterium tumefaciens C58 genome in 2001. We report here consolidation of these sequences, updated annotation, and additional analysis of the evolutionary history of the linear chromosome, which is apparently limited to the biovar I group of Agrobacterium.
Several malignant tumor cells become apoptotic and revert to the benign phenotype upon parvovirus infection. Recently, we demonstrated that the rat parvovirus RPV/UT also induces apoptosis in the rat thymic lymphoma cell line C58(NT)D. However, a minority of cells that escaped apoptosis showed properties different from the parental cells, such as resistance to apoptosis, enhanced cell adherence...
