Use of the 32P-postlabeling method to detect DNA adducts of 2-amino-3-methylimidazolo[4,5-f]quinoline (IQ) in monkeys fed IQ: identification of the N-(deoxyguanosin-8-yl)-IQ adduct.

Abstract

Eight DNA adducts of 2-amino-3-methylimidazolo[4,5-f]-quinoline (IQ) were found by the standard 32P-postlabeling method in livers from male Cynomolgus monkeys fed IQ (5 days/week, 3 weeks, 20 mg/kg, nasal-gastric intubation). The IQ-DNA adduct fingerprints observed in monkeys were identical to those observed in rats that received IQ (0.03%) in the diet for… (More)
