Research Interests

Research interests explore mechanisms of chemical carcinogenesis and its modulation by dietary and environmental factors. Two important cancer preventive agents are being extensively studied — indole-3-carbinol for its promise in prevention of breast cancer, and chlorophyllin, which we are testing in a clinical trial for its potential to reduce aflatoxin-related liver cancer in China. The main experimental model is the rainbow trout, supplemented by studies with traditional rodent models. Biochemical and molecular biology approaches are employed to understand carcinogen and modulator pharmacokinetics, metabolic pathways, DNA damage and repair, mutagenic activation of oncogenes and tumor suppressor genes, cell replication and apoptosis, and how these pathways are altered by dietary treatment with chemopreventive agents. Exploratory studies are examining gene transfer to improve the utility of fish as surrogate models for cancer research. This work is carried out in collaboration with other researchers in the two NIEHS centers at OSU.
