Transformation of a specific clone of Fischer rat embryo (CREF) cells with wild-type 5 adenovirus (Ad5) or the E1a plus E1b transforming gene regions of Ad5 results in epithelioid transformants that grow efficiently in agar but that do not induce tumors when inoculated into nude mice or syngeneic Fi

Abstract
Rat embryo cells were transformed by adenovirus type 2 at different multiplicities of infection. The oncogenic potential of the resulting transformed lines varied considerably but a relationship was found to exist between transforming virus dose and oncogenicity of the resulting transformed lines. Possible reasons for the considerable variation in oncogenicity of the transformed lines are discussed, giving particular consideration to cellular antigenicity and recent molecular biology studies of adenovirus type 2 transformed cell lines.

## Abstract The cell line T637 was derived from BHK21 cells (subline B3) by transformation with adenovirus type 12. The T637 cells contain multiple copies of the viral DNA, with different parts of the viral genomes being represented in unequal amounts. The persisting viral DNA has been shown in pre
We have isolated a revertant cell line (G5) from an adenovirus transformed rat cell line (F4) which failed to express the integrated viral oncogenes. To determine whether the reversion mutation was acting in cis or trans the G5 cells were co-transfected with an El gene bearing expression plasmid and
