Dr. Turner's research program focuses on determining the impact of dietary constituents on regulatory processes that may protect against carcinogenesis and inflammation in the colon. Her lab is evaluating the effects of fiber sources and the specific phytochemicals contained within them on aspects of cellular proliferation or apoptosis, and microbial/epithelial cell interactions. The goal is to determine how these normal processes are being perturbed by chemical carcinogens, radiation or pro-inflammatory compounds, and how diet may mitigate the damage caused by them. Work conducted in the laboratory is currently funded by the United Sorghum Checkoff Board, the California Dried Plum Board, and the National Space Biomedical Research Institute.
