Cancer Lett. 1996 May 15;103(1):65-9.Tumor promoters such as phorbol esters, teleocidin and okadaic acid increase the numbers of multilayered, transformed foci produced by BPV DNA-transfected C3H/10T1/2 cells. We questioned whether arsenic and chromium, which are known human carcinogens also enhance transformation of BPV DNA-transfected C3H/10T1/2 cells. Cr(III) potassium sulfate at 100 microM enhanced transformation by 1.4-fold, but Cr(VI) as potassium chromate did not enhance transformation, although toxicity of potassium chromate may have prevented enhancement of transformation.
