Title: Associate Professor


Phone: 406-243-4769

Office: SB 281


After completing undergraduate work in biology at Texas Tech University in Lubbock, Dr. Pershouse earned a Ph.D. in Biomedical Sciences under the guidance of Professor Elton Stubblefield at the University of Texas Graduate School of Biomedical Sciences in Houston. Following a postdoctoral fellowship at the M.D. Anderson Cancer Center under the supervision of Professor Peter Steck, and a brief postdoctoral associate position at Baylor College of Medicine with Drs Craig Chinault and Allan Bradley, he joined the faculty at The University of Montana as a Research Assistant Professor in September of 2000, was promoted to Assistant Professor in 2002, and to Associate Professor in 2007.


Research Statement

The Pershouse lab focuses on the mechanisms utilized by cancer cells to evade normal growth control. His lab has been studying the role of tumor suppressor genes in various human cancer models. Due to our proximity to Libby, Montana, there is a great deal of interest in mesotheliomas, a tumor tightly linked to asbestos exposure. These studies aim to expand our ability to detect tumor formation at an earlier, more treatable stage, as well as to provide scientists with better targets for effective therapeutics. Dr. Pershouse was a member of one of the competing labs that discovered the PTEN tumor suppressor gene, a gene altered in a high percentage of human tumors.

The laboratory has also begun a new study aimed at providing oncologists with vital information on American Indian genetics that will allow the prediction of chemotherapy drug response. This technology is becoming widely used in the general population, but several key pieces of data are necessary for application in Indian country. This is one of the first studies to target American Indian pharmacogenetics in the country.
