Name: Erica Woodahl
Title: Associate Professor
Office: SB 480
After completing a B.S. in Biochemistry at the University of Notre Dame in 1998, Erica Woodahl received a Ph.D. in Pharmaceutics from the University of Washington in 2004. She completed a postdoctoral fellowship in Clinical Pharmacokinetics at the Fred Hutchinson Cancer Research Center in Seattle. She moved to the University of Montana as an Assistant Professor in 2007 and was promoted to Associate Professor in 2012.
The research in the lab is in the field of pharmacogenomics — the study of the relationship between genetic variation and response to drug therapy. Genetic variation in genes important in drug disposition alters the pharmacokinetics and ADME (absorption, distribution, metabolism, and elimination) of many therapeutic compounds. Our research focuses on pharmacogenomics in drug-metabolizing enzymes and drug transporters to understand interindividual variability in drug response and toxicity.
The first major focus of the lab is to study pharmacogenomics in American Indian populations in partnership with the Confederated Salish and Kootenai Tribes in Northwestern Montana. This work includes the identification and characterization of genetic variation in genes that predict drug response and toxicity (particularly cytochrome P450 drug-metabolizing enzymes), as well as community-based participatory research to aid in the translation of pharmacogenomic research into the clinic. Our initial emphasis is on genes that influence response to cancer chemotherapy. This research is funded by the Northwest-Alaska Pharmacogenomics Research Network (NWA-PGRN) to address pharmacogenomics research in American Indian and Alaska Native (AI/AN) populations.
The second major focus of the lab is to evaluate pharmacogenomics in genes that encode drug transporters. The main drug transporter of interest is P-glycoprotein (ABCB1/MDR1) that is a member of the ATP-binding cassette (ABC) superfamily of transporters. Genetic variability in P-glycoprotein may alter the distribution of drugs into target cells and tissues, the development of multidrug resistance in cancer, and the susceptibility to neurodegenerative diseases such as Parkinson’s disease. We are using a combination of computational, lipid-based (nanodisk), cell-based, and in vivo models to study the functional consequence of genetic variation in P-glycoprotein.
