title: [Oncogen localization in simian adenovirus DNA. I. In vitro rat cell transformation using the SV20 virus and its DNA].
abstract: Cell transformation by the complete and the incomplete virus SV20 was investigated. To compare the oncogenic properties of human adenoviruses, two types of cell systems--the primary rat embryonic cell culture and the primary rat kidney cell culture--were used. The dependence of DNA concentration on transformation frequency was investigated. With the incomplete virus SV20, the transformation efficiency was more than that with the complete virus (16 and 1-3 percent, resp.). In addition, it has been shown that the primary rat kidney cell culture is more sensitive to transformation than the primary rat embryonic cells culture. The new-born Sirian hamsters being inoculated with virus SV20 DNA, the growth of a tumor being registered in the point of injection 120 days afterwards.
