| characterization of a new virus from mus cervicolor immunologically related to the mouse mammary tumor virus. | a virus, similar to the murine mammary tumor viruses (mumtv) of the laboratory mouse mus musculus, was identified in the milk of m. cervicolor popaeus mice. the virus was morphologically indistinguishable from the type-b mumtv and was thus termed mc-mtv. radioimmunoassays for the 52,000-dalton major envelope glycoprotein and the 28,000-dalton major internal protein of mumtv demonstrated that mc-mtv shared some antigenic determinants with both of these mumtv proteins. this reactivity was clearly ... | 1978 | 82634 |
| mammary tumorigenesis in feral mus cervicolor popaeus. | a pedigreed breeding population of feral mus cervicolor popaeus with a high incidence of mammary tumors, arising between 6 and 14 months of age, is described. these mice were chronically infected with a type b retrovirus which is distantly related to the mouse mammary tumor virus (mmtv) of inbred strains of mus musculus. mmtv-induced mammary tumors in inbred mice frequently (80%) contained an insertion of the viral genome into the int-1 or int-2 loci of the tumor cellular genome. these two cellu ... | 1986 | 3009873 |
| a new class of genetically transmitted retravirus isolated from mus cervicolor. | the cocultivation of spleen cells from the southeast asian mouse, mus cervicolor, with heterologous cell lines has permitted the isolation of a new retravirus (designated m432) that can be transmitted to tissue culture cells of the laboratory mouse, m. musculus. cells infected with m432 contain cytoplasmic type a particles and budding forms with compact,spherical nucleoids; extracellular virions lack surface spikes and have a condensed, central core surrounded by an intermediate line. like other ... | 1976 | 62362 |
