| Outline of Final Research Achievements |
In this study, we examined the enhancing effects of carcinogenesis-modifying compounds such as pharmaceutical products and drug transporter inhibitors on the polyaromatic hydrocarbons (PAHs)-mediated physiological function such as arylhydrocarbon receptor (AhR) activation and CYP1A1 induction. The intracellular level of PAHs and its physiological functions were increased by the nicardipine (dihydropyridine calcium channel blockers), curcumin (food components) and specific inhibitors of breast cancer resistant protein (BCRP).
In addition, we succeeded in new assay systems that could predict the absorption from the intestinal tract and toxicological effects of carcinogens. This assay system is useful for screening and analysis of mechanism of carcinogenesis-modifying compounds.
