We tested the ability of phenobarbital and two liver carcinogens, acetoxime and 1-nitroso-5,6-dihydrouracil (NDHU), to induce hyperplastic liver nodules (HLN) in MRC-Wistar and Wistar rats, using a system that included a single diethylnitrosamine (DEN) treatment, partial hepatectomy, and administration of
The hepatocarcinogens 2-nitropropane and acetoxime have previously been found to induce a specific and qualitatively identical pattern of base damage in rat liver DNA and RNA, including the induction of increased levels of 8-hydroxyguanine. Because both 2-nitropropane and acetoxime are
Preparation of adducts from nicotinamide adenine dinucleotide and a number of oximes is described; these include acetoxime, pyruvatoxime, cyclohexanoxime, cyclopentanoxime. These adducts are closely related to the corresponding NAD-ketone adducts in their spectra properties, but they are stable in acid
The genotoxic effects of N-nitroso-N-methylurea (MNU) and acetone oxime (ACOX) were tested in the Somatic Mutation and Recombination Test (SMART) in Drosophila melanogaster. We have performed the same assay on transgenic flies expressing the human gene encoding a glutathione S-transferase
The hepatocarcinogenicity of acetoxime has been tentatively linked with its metabolic oxidation to the potent genotoxicant and carcinogen propane 2-nitronate (P2-N). In order to test the hypothesis that acetoxime is metabolized to P2-N, the oxime (20 mM) was incubated with
