Characteristics of cores of avian leuko-sarcoma viruses

Virology, 1970
Abstract Rous sarcoma virus-Rous associated virus (RSV-RAV 1 ) mixtures were treated to remove lipoprotein envelopes, and the resulting virion cores were analyzed. Cores labeled with uridine- 3 H had a density (1.27 g/ml) different from intact virus (1.16 g/ml) and could be separated by isopycnic banding in potassium tartrate, cesium sulfate, or ...

Alterations in the genomes of avian sarcoma viruses

Virology, 1982
We describe 12 nonconditional mutants of avian sarcoma virus. Eleven were replication defective and one appeared to retain wild-type functions. Comparison of restriction endonuclease digests of viral DNA revealed that 8 of 11 replication defectives contained large deletions of viral information.

Avian sarcoma viruses, protein kinases and cell transformation

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1983
The first RNA tumour virus to be isolated and identified as such was the Rous sarcoma virus (RSV), which causes the transformation of cells in culture as well as fibrosarcomas when injected into suitable host animals (for reviews see Hanafusa (1977) and Bishop (1978)).

Polyethylene glycol-mediated infection with avian sarcoma viruses

Archives of Virology, 1978
In this communication we report that fusion of viral and cellular membranes by polyethylene glycol is a convenient approach to overcoming genetically determined resistance to infection. Using this method, avian sarcoma virus-transformed mammalian cells have been produced which serve as useful model systems for the study of Rous sarcoma virus-specific ...

Phenotypic mixing between reticuloendotheliosis virus and avian sarcoma viruses

Virology, 1977
Abstract Coinfection of chicken embryo fibroblasts with reticuloendotheliosis virus (REV) and avian sarcoma virus leads to the formation of avian sarcoma viral pseudotypes which carry envelope determinants of REV. These pseudotypes can be neutralized by REV antiserum, have a host range which is different from that of any known avian sarcoma virus ...

Defective Avian Sarcoma Viruses

1983
This review was intended initially as a reference source for those interested in the origins and first descriptions of the defective avian sarcoma viruses. Quite a few of these viruses have been characterized in the past few years and their varied nomenclature according to source, discoverer, date of isolation or biological properties could result in ...

Chemical crosslinking of proteins in avian sarcoma and leukemia viruses

Virology, 1980
Abstract We have investigated the nearest neighbor relationships of proteins in avian sarcoma and leukemia viruses by means of bifunctional crosslinking agents. In intact virions dimethyl suberimidate and dithiobispropionimidate induce the formation of covalently linked multimeric species of all four internal structural proteins ( gag proteins).

Ultraviolet inactivation of avian sarcoma viruses: Biological and biochemical analysis

Virology, 1976
Abstract The rate of inactivation by ultraviolet light of the focus-forming capacity of avian sarcoma virus was almost the same as that of the virus-producing capacity, measured as plaque formation. In addition, no significant difference was observed in inactivation of the transforming capacity assayed on C/BE chick embryo fibroblasts (CEF), which ...
