2-Nitronaphthalene (2NN) has been identified as a mutagenic atmospheric reaction product of naphthalene in the Ames bacterial reversion assay. Recent experiments have shown this nitroarene to be genotoxic in a human lymphoblastoid cell line (MCL-5) transfected with plasmids encoding epoxide
Salmonella typhimurium YG1024 is a derivative of S. typhimurium TA98 with a high level of N-hydroxyarylamine O-acetyltransferase (OAT) activity. We have demonstrated that this strain is highly sensitive to the mutagenic actions of N-hydroxyarylamines derived from aromatic amines and nitroarenes.
We have previously shown that retinol pretreatment limits the amount of pulmonary injury caused by 1-nitronaphthalene in male Sprague-Dawley rats. The main objective of this study was to determine if retinol pretreatment can protect the lung from the toxicity of
1-nitronaphthalene.
