Research Project: ONE-CARBON NUTRIENTS IN THE PREVENTION OF CANCER

Location: Human Nutrition Research Center on Aging

Project Number: 1950-51000-074-01
Project Type: Specific Cooperative Agreement

Start Date: May 01, 2009
End Date: Apr 30, 2014

Objective:
1. To define the role that availability of each of the one-carbon nutrients plays in determining the risk of common cancers and to determine the nature of the interactions between these nutrients in this regard. 2. Determine how genetic differences interact with dietary antagonists of one-carbon nutrients in determining cancer risk. (PDRAM NAA09). 3. To determine how obesity enhances the risk of cancer, to find means of ameliorating this risk, and to define other factors that interact with obesity to further modify its effects.

Approach:
Appropriate alterations in dietary and nutritional habits have an important role to play in cancer prevention. The nutrients involved in one-carbon metabolism (methionine, choline and the B-vitamins, folate, B12, B6, and B2), as well as obesity, have drawn considerable attention in this regard and are the focus of this laboratory. Our mission is to examine the complex roles that obesity and these 1-carbon nutrients play in modifying metabolic and genetic pathways that lead to human carcinogenesis and thereby define the means by which cancers can be nutritionally prevented. The program of research emphasizes how dietary intake interacts with genetic background to modify molecular and signaling pathways which alter the development of cancers and to examine how other exogenous factors, such as alcohol consumption also play a role. The laboratory focuses on colorectal cancer and breast cancer and utilizes animal studies, cell culture studies, and human studies to accomplish our research goals.
