Abstract/OtherAbstract:
Pre-treatment of baby hamster kidney (BHK) cells with 8-methoxypsoralen (8-MOP) plus ultraviolet (UV) light enhances the frequency of their transformation by polyoma (Py) virus. Of the doses tested, 0.5 microgram/ml 8-MOP plus 0.3 J/cm2 UV-light results in maximal (30-fold) stimulation of viral transformation. 8-MOP alone does not affect viral transformation and UV-light alone causes only a slight increase in the transformation frequency. Thus the drug and light act synergistically in promoting the effect. Treatment of BHK cells with drug plus light without Py infection does not lead to a transformed morphology. A drug-light combination (0.01 microgram/ml 8-MOP plus 1.2 J/cm2 UV) that inhibits cellular DNA synthesis to 75% of control at 28 hr after treatment results in a 6-fold stimulation of the transformation frequency.
