[Enhancement of the transforming activity of simian adenovirus S5 and of the DNA from human adenovirus type I by benzo(a)pyrene and TPA].
Benz(a)pyrene in a concentration of 2.5 micrograms/ml produced a 3.3-fold increase in the transforming activity of simian adenovirus S5 in primary cultures of rat kidney cells. Under analogous conditions TPA increased (2.1 times) the transforming activity of DNA of human adenovirus of type I (AdI). PX5 cells (cotransformed by S5 and benz(a)pyrene) induced tumours in 100% of syngeneic and 81% xenogeneic animals. PX4 cells (transformed by S5 only) induced tumours in 60% of syngeneic animals. Cells transformed by DNA AdI and DNA AdI + TPA did not induce tumours in animals.
