摘要:
The viral DNA sequences present in the human embryo kidney cell line (293) transformed from sheared adenovirus 5 fragments (F. L. Graham, P. S. Abrahams, C. Mulder, H. L. Heijneker, S. 0. Warnaar, F. A. deVries, W. Fiers, and A. J. van der Eb 1974, Cold Spring Harbor Symp. Quant. Biol.39, 637-650) were analyzed. By renaturation kinetics of transformed cell DNA and labeled adenovirus 5 restriction enzyme fragments obtained with HindIII we determined that there are four to five copies per cell of the left 12% of the viral genome and approximately one copy per cell of 9% of the right end of the viral genome. Analysis of the RNA sequences transcribed in nuclei isolated from this cell line indicated that only transcripts from the sequences of the left end were detected. The expression of these viral sequences was mediated by DNA-dependent RNA polymerase II. Analysis of the viral DNA from 293 cells using restriction enzymes reveals that the viral DNA is integrated and located at two sites on the cellular genome. This simple arrangement is stable through several cell passages. © 1979.
