Influence of 5‐bromodeoxyuridine on the expression of avian GS antigen in mammalian rous sarcoma virus‐transformed cells

Abstract

The avian group-specific (gs)

Incomplete viral genome in a non‐virogenic mouse tumour cell line (RVP3) transformed by prague strain of avian sarcoma virus

“…Caution must be exercised on this point in view of the absence of SR-RSV DNA sequences in RVA, tumour cells. On the basis of complement fixation and immunofluorescence tests, the gag gene does not appear to be expressed in RVP, cells and may be absent (Bubenik and Bauer, 1967;Sovova et al, 1974). If truly cryptovirogenic transformed mammalian cells can be identified, they would represent a…”
