Neoplastic transformation of rabbit cells by murine sarcoma viruses. 1982

J S Rhim, and H G Bedigian, and R R Fox

Neoplastic transformation of rabbit cells by Kirsten murine sarcoma virus (Ki-MSV), the Ki-MSV pseudotype of baboon endogenous virus (Ki-MSV[BaEV]) and the Moloney-MSV pseudotype of feline leukemia virus (M-MSV[FeLV]) is reported. Rabbit cells can be readily transformed by Ki-MSV, Ki-MSV(BaEV) and M-MSV(FeLV). Rabbit cells transformed by Ki-MSV and M-MSV(FeLV) were found to be virus producers, whereas those transformed by Ki-MSV(BaEV) were nonproducers (NP). The NP cells were obtained by simply infection rabbit cells with Ki-MSV(BaEV) and subculturing the infected cells. Although the morphologically altered NP cells did not produce infectious virus or murine leukemia virus antigen, they did contain a rescuable MSV genome. All of the transformed cells formed colonies in soft agar, grew to high saturation densities and produced tumors when transplanted into nude mice. The Ki-MSV and M-MSV(FeLV)-transformed cells produced tumors in newborn WH/J rabbits, thus providing an important tool for studying tumor immunity in the rabbit.

UI MeSH Term Description Entries
D007708 Kirsten murine sarcoma virus A replication-defective murine sarcoma virus (SARCOMA VIRUSES, MURINE) capable of transforming mouse lymphoid cells and producing erythroid leukemia after superinfection with murine leukemia viruses (LEUKEMIA VIRUS, MURINE). It has also been found to transform cultured human fibroblasts, rat liver epithelial cells, and rat adrenocortical cells. Kirsten Sarcoma Virus,Sarcoma Virus, Kirsten,Virus, Kirsten Sarcoma
D008979 Moloney murine leukemia virus A strain of Murine leukemia virus (LEUKEMIA VIRUS, MURINE) arising during the propagation of S37 mouse sarcoma, and causing lymphoid leukemia in mice. It also infects rats and newborn hamsters. It is apparently transmitted to embryos in utero and to newborns through mother's milk. Moloney Leukemia Virus,Leukemia Virus, Moloney,Virus, Moloney Leukemia
D011817 Rabbits A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.

D002472 Cell Transformation, Viral An inheritable change in cells manifested by changes in cell division and growth and alterations in cell surface properties. It is induced by infection with a transforming virus. Transformation, Viral Cell,Viral Cell Transformation,Cell Transformations, Viral,Transformations, Viral Cell,Viral Cell Transformations
D005347 Fibroblasts Connective tissue cells which secrete an extracellular matrix rich in collagen and other macromolecules. Fibroblast
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
