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.

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


DNA Damage and Repair

DNA damage and repair mechanism is vital for maintaining DNA integrity. Damage to cellular DNA is involved in mutagenesis, the development of cancer among others.

Carcinogenesis and Epigenetics

Cancer research has revealed that the classical model of carcinogenesis, a three step process consisting of initiation, promotion, and progression, is not complete.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
