title: Transformation of African green monkey kidney cells by irradiated adenovirus 7-simian virus 40 hybrid.
abstract: The ability of adenovirus 7-simian virus 40 (SV40) hybrid (strain LL "E-46") to replicate decreased exponentially as a function of the amount of gamma-irradiation; the ability to induce SV40 and adenovirus 7 T antigen decreased at a much slower rate. Nevertheless, the virus was still able to transform African green monkey kidney cells at a radiation dosage that had completely destroyed its replication ability. All transformed colonies were positive for SV40 T antigen but were negative for adenovirus 7 T antigen. The adenovirus 7-SV40 hybrid transformed cells were superinfectible with SV40 virus. Two of the three transformed cell populations apparently did not sensitize hamsters against the appearance SV40 primary tumors, thus suggesting a deficiency in the SV40 transplantation antigen.
