Center of Molecular Toxicology and Carcinogenesis
Laboratory of Dr. Curtis Omiecinski
Professor and Hallowell Chair

Welcome to the Omiecinski Laboratory Website! The research area of our
laboratory is that of Molecular Toxicology. Our research centers on the study of
human variability in chemical detoxication, an area termed ‘toxicogenomics.’
Detoxication pathways under investigation include the cytochrome P450 oxidation
and epoxide hydrolase metabolism systems. We are working to characterize genetic
differences within enzymes and within their respective regulatory networks that
dictate interindividual responses to drug and chemical exposure. The regulatory
pathways involved include certain members of the nuclear receptor superfamily,
such as the constitutive androstane receptor, or CAR. These ‘xenobiotic’
receptors function to sense the chemical environment in cells and then adjust
the levels of biotransformation activity to accommodate specific exposure
situations. The receptor control circuits exhibit diversity within cells,
tissues and among individuals, in part due to the use of alternative RNA
splicing mechanisms – an area of research focus of the laboratory. Transgenic
mouse, primary cell culture and stem cell models are used in these
investigations.
