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

Ketoximes undergo a cytochrome P450-catalyzed oxidation to nitric oxide and ketones in liver microsomes. In addition, nitric oxide synthase (NOS) can catalyze the oxidative denitration of the >C=N-OH group of amidoximes. The objective of this work was to characterize the
Acetoxime (ACO) and 2-nitropropane (2-NP), both industrially important chemicals and known hepatocarcinogens in rats, induced increased levels of 8-hydroxy-guanine in liver DNA and RNA of male Sprague-Dawley and F344 rats after either oral or i.p. administration. Both compounds also produced
