title: [Induction of endogenous C-type virus by 5-iododeoxyuridine and augmentation of this induction by polycyclic hydrocarbons].
abstract: When the MLg Mouse cells were treated with the chemical carcinogens, in the presence of microsomal enzymes and NADPH2 after 5-iododeoxyuridine (IUdR) treatment, the induction frequency of the endogenous C-type virus was increased by nearly 10-fold in comparison with the cultures treated with IUdR only. In the preliminary screening of several polycyclic hydrocarbons including carcinogenic and non-carcinogenic products, apparently there was no correlation between the carcinogenecity in vivo and the stimulation capacity of IUdR induced C-type virus activation in our test conditions.
