The binding of polycyclic aromatic hydrocarbon diol-epoxides to DNA.

abstract：:Binding of 1-nitro[14C]pyrene (1-NP) or its metabolites to cellular DNA and protein in cultures of rabbit alveolar macrophages and lung and tracheal tissues was examined. DNA binding was highest in tracheal tissue (136.9 +/- 18.3 pmol 1-NP/mg DNA). DNA binding in macrophages and lung tissue was one-fifth of the level ...
