Elizabeth Putnam is Associate Professor of Molecular Genetics and Toxicology at the University of Montana. She currently serves as Interim Dean of the Davidson Honors College. After completing undergraduate work in Biochemistry at Rutgers College in New Brunswick, NJ, Elizabeth Putnam earned a Ph.D. in Biomedical Sciences from the University of Texas Graduate School of Biomedical Sciences in Houston. Following postdoctoral fellowships at M.D. Anderson Cancer Center and the University of Texas Medical School, she moved to the University of Montana in 2000. She is currently a tenured Associate Professor.
Research in the Putnam laboratory focuses on the control of protein production related to lung fibrosis, using asbestos-caused fibrosis as a model system. We have identified SPARC, a matricellular protein involved in tissue repair, extracellular matrix (ECM) regulation, cellular proliferation, and cellular adhesion, as a candidate for involvement in the fibrosis that occurs after asbestos exposure. My laboratory is funded to explore the control of SPARC expression after asbestos exposure via RNA interference and thus fibrosis development as well.
My research efforts include outreach to rural and underserved communities, beginning with the community of Libby, Montana when I arrived at the University of Montana in 2000. My funding has included projects to provide comprehensive, collaborative and participatory initiatives that specifically increased community understanding of the interplay between genes and environment. We currently have funding to support our efforts to determine, in American Indian/Alaska Native populations, population-specific polymorphism frequencies in genes involved in drug metabolism and transport. The data obtained will enable physicians treating these patients to choose appropriate therapies with reduced potential for deleterious side effects. Another effort on this CBPR project is to develop culturally appropriate materials for genetic education of our partners.
Research in the Putnam laboratory focuses on the role of genetic variability in susceptibility to environmental insult. Â Inherited differences in DNA sequence contribute to phenotypic variation, influencing an individualâÂ€Â™s risk of disease and response to the environment. Â Investigations into gene expression changes after exposure to environmental toxins provide insight into possible mechanisms of response, and the influence of genetic polymorphisms on expression of this response.Â Using the latest technologies for microarray analysis and automated DNA sequencing, these studies hold great promise for dissecting response to environmental toxins and identifying potential targets for therapeutic intervention.
