Application

Benzo[a]pyrene (PAH), a polycyclic aromatic hydrocarbon pollutant, is used as a chemical carcinogen in experimental models of cancer. Carcinogenesis depends on it′s oxidation by CYP1A1 to benzo[a]pyrenediolepoxide, that forms depurinating adducts with DNA that dissociate to form abasic lesions. Benzo[a]pyrene is a ligand for the arylhydrocarbon receptor (AhR), and some of its biological effects, including the induction of CYP1A1, appear to be mediated via activation of the AhR.

Benzo[a]pyrene (B[a]P) is a polycyclic aromatic hydrocarbon formed by the incomplete combustion of organic matter. Environmental B[a]P contamination poses a serious health risk to many organisms because the pollutant may negatively affect many physiological systems. As such, chronic exposure to

Benzo[a]pyrene (BaP) is an agonistic ligand for the aryl hydrocarbon receptor (AhR) and a major environmental carcinogen implicated in the aetiology of lung cancer through the induction of benzo[a]pyrene diol epoxidation (BPDE) and BPDE-DNA adducts. Because BaP metabolization requires cytochrome

The physiological role of aryl hydrocarbon receptor (AhR) is not yet fully understood, and investigation is hampered by the limited solubility of reported AhR ligands in aqueous media. To achieve improved solubility, we focused on our previous finding that planarity-disruption

Several experimental models have been developed to study respiratory tract carcinogenesis. The most widely applied in vivo model uses Syrian golden hamsters which receive intratracheal instillations of a suspension of benzo[a]pyrene (B[a]P) particles attached to ferric-oxide (Fe2O3) particles in saline;
