| isolation of rd-114-like oncornavirus from a cat cell line. | a clone of cells derived from a continuous line of cat cells (ccc) spontaneously produced an rna c-type virus (ccc virus) which did not have the group-specific antigen of the standard strains of feline leukemia viruses but did have that of the rd-114 virus. single-hit infection of a virus yielding ccc cell with only the feline leukemia virus pseudotype of murine sarcoma virus [msv(felv)] resulted in the release of a pseudotype of msv coated with the ccc virus envelope. host range, transmission o ... | 1973 | 4123287 |
| mutants of nonproducer cell lines transformed by murine sarcoma virus. ii. relationship of tumorigenicity to presence of viral markers and rescuable sarcoma genome. | tumorigenic and nontumorigenic mutants induced by a single 5'-bromodeoxyuridine (brdu) treatment of a nonproducer (np) tumorigenic cell line were isolated and characterized. among the cloned derivatives were examples of virus-free and sarcoma virus-producing cell lines. oncogenicity did not correlate with production of virus or ease of rescue of the sarcoma genome. all lines, including nononcogenic derivatives, retained the sarcoma genome. phenotypic reversion of some cell mutants was observed a ... | 1973 | 4124209 |

| harvey sarcoma virus: a second murine type c sarcoma virus with rat genetic information. | the nucleic acid sequences found in the harvey strain of murine sarcoma virus have been analyzed by rna.[(3)h]dna and [(3)h]rna.dna hybridization techniques. the harvey strain of murine sarcoma virus has been found to possess at least two sets of nucleic acid sequences. one set of sequences is contained in the moloney strain of mouse type-c virus, and the other set is contained in dna transcripts synthesized in endogenous reactions containing rat type-c virus(es). the nucleic acid sequences that ... | 1974 | 4364897 |
| simple, quantitative assay for both xenotropic murine leukemia and ecotropic feline leukemia viruses. | a cat cell line carrying the genome of a murine sarcoma virus developed discrete foci in linear response to infection with feline leukemia virus or xenotropic murine c-type virus. | 1974 | 4365331 |
| activation of the murine sarcoma virus genome after infection with the murine leukemia virus as determined by cell agglutination. | non-virus-producing nih/3t3 cells transformed by the murine sarcoma virus are agglutinated by conconavalin a to the same low level as normal nih/3t3 cells. infection with the murine leukemia virus greatly increases the agglutination of transformed cells but not that of normal cells. these data suggest that the morphological expression of cell transformation and the surface alterations associated with increased cell agglutination are controlled by the expressions of different sarcoma virus genes. | 1974 | 4363245 |
| murine virus-induced proteins synthesized by hamster tumor cells transformed by, but not producing, murine sarcoma virus. | the 8303 hamster tumor cells transformed by moloney strain of murine sarcoma virus (m-msv), but which do not produce virus, do contain murine virus-induced proteins. the virus-induced proteins within the cell were identified either as free proteins or in association with membranous material, including the plasma membrane. in addition, some were excreted by the 8303 hamster tumor cells into the growth medium. most virus-induced proteins were larger than 68,000 daltons, and they did not dissociate ... | 1974 | 4359302 |
