Research Interests

My research interests relate to understanding the mechanisms by which components of diet, particularly constituents of plant foods, alter risk factors for cancer. We use controlled dietary studies and other types of interventions in humans to examine biologic responses to diet and to evaluate biomarkers of dietary exposure. Several of our recent studies have focused on gene-diet interactions in relation to biotransformation enzyme activities. Numerous low-penetrance, high-prevalence genetic polymorphisms in metabolizing enzymes, such as the cytochromes P450 and conjugating enzymes (e.g., glutathione S-transferases, UDP-glucuronosyltransferases), can contribute to interindividual variation in enzyme activities. Many of these enzymes metabolize and inactivate potential carcinogens and cancer-promoting agents. They can also metabolize various compounds in plant foods and can be induced by specific phytochemicals. The relationship between genetic differences in enzyme activities and differences in plant food intake may be an important determinant of cancer susceptibility. Controlled feeding studies in humans are a useful method to examine these interactions.

The Lampe laboratory also investigates the metabolism and activities of isoflavones and lignans (estrogenic compounds found in soybeans and other plant foods). The phytoestrogens, like other plant food constituents, are made more biologically active when they undergo bacterial metabolism in the colon. Differences in colonic bacterial populations and aspects of diet that alter colonic environment influence exposure to potential chemoprotective agents. We are using cross-sectional, intervention, and in vitro studies to determine how dietary factors contribute to these differences in metabolism, whether metabolism can be altered by diet, and what are the biologic implications of these metabolic differences, particularly in relation to colorectal neoplasia. The laboratory also measures phytoestrogen concentrations in biologic samples for several large-scale epidemiologic studies.
