title: Mammalian culture systems for the study of genetic effects of N-substituted aryl compounds.
abstract: Liver-derived intact cell systems are useful for examination of the genetic effects of N-substituted aryl compounds. With freshly isolated hepatocytes, the hepatocyte primary culture-DNA repair test detects the genotoxicity of a spectrum of activation-dependent aryl amines and amides. Likewise, continuous lines of adult rat liver epithelial cells are mutated at the hypoxanthine-guanine phosphoribosyl locus by such compounds. Hepatocyte-mediated mutagenesis enhances the activation of aromatic amines to mutagenic metabolites. These intact cell systems provide a balance of detoxification and activation reactions for evaluation of tissue profiles of metabolism and capability for the production of genotoxic metabolites.
