Dibenzo [a,l]pyrene (DB[a,l]P), an extremely potent environmental carcinogen, is metabolically activated in mammalian cells and microsomes through the fjord-region dihydrodiol, trans-DB[a,l]P-11,12-diol, to synand anti-DB[a,l]P-11,12-diol-13,14-epoxides (syn-and anti-DB[a,l]PDEs). The role of seven
## Abstract We hypothesized that chlorophyllin (CHLN) would reduce benzo[__a__]pyreneβDNA (BPβDNA) adduct levels. Using normal human mammary epithelial cells (NHMECs) exposed to 4 ΞΌM BP for 24 hr in the presence or absence of 5 ΞΌM CHLN, we measured BPβDNA adducts by chemiluminescence immunoassay (C
