title: A benzo[a]pyrene metabolite-DNA adduct occurring in the activating cell but not in exogenous DNA.
abstract: [3H]Benzo[a]pyrene (BP) and salmon sperm DNA were incubated with hepatocytes from 5,6-benzo-flavone-treated rats. The cellular DNA and the exogenously added DNA were separately isolated, hydrolyzed and chromatographed on a Sephadex LH-20 column. The extracellular DNA yielded 3 peaks of radioactivity in the chromatographic eluate. The cellular DNA contained an additional peak suggesting the formation of a DNA adduct from a metabolite that does not leave the cell.
