| Harvey sarcoma virus | <oncogene> One of a family of oncogenes, first identified as transforming genes of Harvey and Kirsten murine sarcoma viruses. (Name from rat sarcoma because Harvey virus, though a mouse virus, obtained its transforming gene during passage in a rat). Transforming protein coded is p21ras, a GTP-binding protein with GTPase activity, that resembles regulatory G-proteins. (18 Nov 1997) |

| Moloney murine sarcoma virus | <molecular biology, virology> Replication defective retrovirus, source of the oncogene v mos, responsible for inducing fibrosarcomas in vivo and transforming cells in culture. (18 Nov 1997) |
| murine sarcoma virus | A seemingly defective retrovirus that produces sarcomas in mice when growing in the presence of a "helper" virus; e.g., mouse leukaemia virus. (05 Mar 2000) |
| sarcoma viruses, murine | Species of replication-defective mammalian type c retroviruses (retroviruses type c, mammalian) which are capable of transforming cells, but which replicate and produce tumours only in the presence of murine leukaemia viruses (leukaemia viruses, murine). (12 Dec 1998) |
| Cushing, Harvey | <person> This leader of neurosurgery was born in Cleveland, Ohio, graduated from Harvard in 1895, remained at Massachusetts General Hospital for one year, spent 15 years at Johns Hopkins, returned to Harvard as Professor of Surgery, and retired in new Haven where he continued actively until his death. Cushing's accomplishments in neurosurgery were amazing. In 1906, he demonstrated the relationship between pituitary tumours and sexual infantilism. In 1917, he published a classic, "The Pituitary Body and Its Disorders." Cushing wrote many charming essays, some of which were published as a collection under the title, "Consecratio Medici" in 1928. He was an earnest collector of books and bequeathed his valuable collection to the Yale Library. Among his many publications were a Biography of 0sler, and a Biography of Andreas Vesalius. Lived: 1869-1939. (15 Nov 1997) |
| Harvey | William, 1578-1657. English anatomist, physiologist, and physician who first described the circulation of the blood in 1628. He understood that the interventricular septum is not porous so blood can not pass through it. He demonstrated the volume of blood which passes unidirectionally through a segment of a peripheral vein exceeds the volume of blood within the body, so blood must recirculate. He described the organization of the foetal circulation and the transition to the postnatal organization. (05 Mar 2000) |

| Abelson murine leukaemia virus | A retrovirus belonging to the Type C retrovirus group subfamily (family Oncovirinae) which is associated with leukaemia and produces in vitro transformation of mouse cells. (05 Mar 2000) |
| gastroenteritis virus, murine | A species of the coronavirus genus causing hepatitis in mice. Four strains have been identified as mhv 1, mhv 2, mhv 3, and mhv 4 (also known as jhm, which is neurotropic and causes disseminated encephalomyelitis with demyelination as well as focal liver necrosis). (12 Dec 1998) |
| Moloney murine leukaemia virus | <molecular biology, virology> Replication competent retrovirus (Oncovirinae) that causes leukaemia in mice, isolated by Moloney from cell free extracts made from a transplantable mouse sarcoma. (18 Nov 1997) |
| murine leukaemia virus | <virology> A group of type C retroviruses infecting mice and causing in some strains lymphatic leukaemia after a long latent period. Nearly all are replication competemt and v onc minus. See: Abelson leukaemia virus. (18 Nov 1997) |
| theiler's murine encephalomyelitis virus | A species of cardiovirus which causes poliomyelitis in rats. It should not be confused with the strain of encepalomyocarditis virus called encephalomyelitis virus, murine, which is also a cardiovirus. (12 Dec 1998) |
| encephalomyelitis virus, murine | A strain of encephalomyocarditis virus, a species of cardiovirus, usually causing an inapparent intestinal infection in mice. A small number of mice may show signs of flaccid paralysis. (12 Dec 1998) |
| Friend murine leukaemia virus | <virology> Murine leukaemia virus isolated by Charlotte Friend in 1956 whilst attempting to transmit the Erlich ascites tumour by cell free extracts. Causes an unusual erythroblastosis like leukaemia, in which anaemia is accompanied by large numbers of nucleated red cells in blood. does not carry a host derived oncogene, but seems to induce tumours by proviral insertion into specific regions of host genome.
