Sensitivity to γ rays of avian sarcoma and murine leukemia viruses

Virology, 1980
Abstract The direct inactivation of avian and murine oncoviruses by γ rays was examined using 60 Co as a γ-ray source. The inactivation of murine leukemia virus (M-MuLV) followed single-hit kinetics with a target size comparable to the molecular weight of its genomic RNA.

Genetic stability of the sarcoma viruses in murine and avian sarcoma virus‐transformed nonproducer cells

International Journal of Cancer, 1972
AbstractClonal lines of murine and avion sarcoma virus‐transformed mammalian cells, in which the viruses do not productively replicate, were studied for the occurrence of spontaneous or chemical‐induced morphologic reversion. From over 10,000 single‐cellderived clones of MSV‐transformed nonproducer cells examined, only one morphologic revertant was ...

Cytoskeletal changes induced by two avian sarcoma viruses: UR2 and Rous Sarcoma Virus

Virology, 1984
UR2-transformed cells were examined by immunofluorescence and compared to control cells and cells transformed by Rous Sarcoma Virus (RSV). Actin and tubulin which are normally depolymerized in RSV-transformed cells appeared to be unaffected by UR2 transformation.

Abortive infection of Japanese quail cells with avian sarcoma viruses

Virology, 1972
Abstract The replication of Prague strains of Rous sarcoma virus (PR RSV) and avian sarcoma virus B77 in Japanese quail cells is abortive in a quantitative sense. Although efficient infection of quail cells, as evidenced by transformation, was obtained with these viruses, the yield of progeny was suppressed by 102-fold or more relative to the chick ...

Temperature-sensitive mutants of avian sarcoma viruses: Genetic recombination between multiple or coordinate mutants and avian leukosis viruses

Virology, 1976
Five coordinate temperature-sensitive mutants of avian sarcoma viruses which fail to transform or produce infectious progeny at 41° have been analyzed by genetic recombination. Four, namely LA334, 336, 338, and 343, carry multiple mutations. One of these mutations is always in the src gene affecting initiation and maintenance of transformation.

[32] Biological techniques for avian sarcoma viruses

1979
Publisher Summary This chapter describes a quantitative and reproducible assay of Rous sarcoma virus (RSV), the focus assay, and methods for obtaining cloned preparations of RSV, through both the focus and soft agar-colony assays. Large-scale growth of RSV is discussed in the chapter.

Surface Alterations in Cells Infected by Avian Leukosis-Sarcoma Viruses

1976
The regulatory mechanisms involved in morphogenesis and in the subsequent maintenance of the differentiated state are poorly understood. However, it is clear that ontogenesis requires that cell proliferation and differentiation be strictly controlled to ensure appropriate development of the organism. If we accept hypothetically that it is primarily the
