Isolation from the asian mouse Mus caroli of an endogenous type C virus related to infectious primate type C viruses.
Treatment of a cell line derived from the Asian feral mouse Mus caroli with 5-bromodeoxyuridine induces an infectious, xentropic type C virus. This virus shares strongly cross-reactive reverse transcriptase (RNA-dependent DNA polymerase) and p30 antigens and crossinterferes with type C viruses isolated from a woolly monkey (SSAV) and gibbon apes (GALV). By similar criteria, the caroli virus is ...
متن کاملType C viral antigens in man. I. Antigens related to endogenous primate virus in human tumors.
Partially purified extracts from 33 human tumors of several histologic types were used as competing antigens in a radioimmunoassay for the p30 protein of an endogenous primate type C virus (M7). Antigens immunologically related to the p30 protein of the M7 virus were detected in two tumors. Like viral p30 antigens previously identified in tissues of several other primates, the antigens found in...
متن کاملOncogenicity of an endogenous C-type virus chemically activated from mouse cells in culture.
RNA C-type viruses are known to exist in an unexpressed form in all mouse cells. These endogenous viruses can be activated from cells in tissue culture under certain experimental conditions. The biologic activity in vivo of one class of chemically-activated C-type virus has been studied. This virus is shown to induce a specific tumor, lymphatic leukemia, in mice of a low leukemic incidence strain.

Endogenous C-type viruses of BALB-c cells: frequencies of spontaneous and chemical induction.
A sensitive biological assay has been developed for studying the frequency of virus induction from mouse cells containing poorly infectious endogenous C-type viruses. A low spontaneous frequency of virus activation of one but not a second endogenous virus of BALB/c cells has been demonstrated. The resistance of BALB/c cells to superinfection by the more inducible virus appears to be absolute, w...
