Chicken embyro lethal orphan (CELO) virus DNA present in hamster cell lines derived from CELO-induced hepatomas.
The kinetics of renaturation of the isolated DNA fragments of chicken embryo lethal orphan (CELO) virus generated by the restriction enzyme EcoR1 was measured in the presence of DNA extracted from two lines of CELO virus-induced hamster hepatoma cells and from control hamster cells. One hepatoma cell line (CILT-2), which did not produce the CELO virus tumor (T) antigen, lacked sequences from about one-half the virus genome while the other hepatoma cell line (CEHEP), which did produce the CELO virus T antigen, lacked sequences corresponding to one-fifth of the viral genome.
