title: Oral administration of the renal carcinogen, potassium bromate, specifically produces 8-hydroxydeoxyguanosine in rat target organ DNA.
abstract: Following oral administration of a renal carcinogen, potassium bromate (KBrO3), to the rat, a significant increase of 8-hydroxydeoxyguanosine (8-OH-dG) in kidney DNA was observed. In the liver, a non-target tissue, the increase in 8-OH-dG was not significant. The non carcinogenic oxidants, NaCIO and NaCIO2, had no effect on 8-OH-dG formation in kidney DNA. These results suggest that formation of 8-OH-dG in tissue DNA is closely related to KBrO3 carcinogenesis.
