Expression of integrated viral DNA sequences outside the transforming region in eight adenovirus-transformed cell lines.
The expression of early and intermediate-early viral regions in eight adenovirus type 5 transformed cell lines was analyzed by radioimmuno-inhibition and RNA-DNA hybridization techniques. Details on the arrangement of the integrated viral DNA sequences in these cell lines have already been published (Visser, L., Wassenaar, A.D.C., Van Maarschalkerweerd, M.W. and Rozijn, T.H. (1981) J. Virol, 39, 684-693). In all cell lines tested, proteins encoded by the transforming region E1 are present. Dependent on the viral DNA content, additional early regions are expressed in most cell lines. In two of the cell lines polypeptides related to the adenoviral terminal protein, encoded by the recently described region E2b, could be detected. The viral DNA sequence encoding the body of the terminal protein mRNA is probably integrated intact, but the promoter region and at least some of the leaders are lacking in these cell lines.
