Research in my laboratory has two foci. The first concerns the ability of nutrients such as vitamin A and omega-3 fatty acids to prevent colon cancer metastasis. The second area, relates to the effect of diet on maternal and offspring behavior and brain metabolism. We use mouse and rat models as well as biochemical and molecular techniques.
We are currently determining how omega-3 fatty acids decrease colon cancer cell division and prevent metastasis using a variety of in vitro molecular techniques. We hope to expand this work and develop a clinically-relevant mouse model for colon cancer metastasis. Most mouse models for studying metastasis are immunodeficient and inject cells at sites unrelated to where the tumor originates in humans. For example, tumor cells would be injected subcutaneously or intrasplenically to study colon cancer metastasis. To overcome these shortcomings, we are currently developing a syngeneic, orthotopic mouse model to study the effect of diet on the immune system and colon cancer metastasis at the appropriate physiological site. The cells injected into the mice express luciferase, allowing us to detect the tumor cells in living mice and follow the metastatic progression.
Previously we have shown that omega-3 fatty acid supplementation increases the ability of rat mothers to adapt to stress. Recently we showed that pups exhibit a reduced stress response and decreased risk-seeking behavior when their dams, but not the pups themselves are supplemented with omega-3 fatty acids during neurodevelopment. Brains from dams were mapped for cytochrome oxidase (CO) activity with a quantitative histochemical method used to identify networks of altered brain regions. Omega-3 fatty acid supplementation appeared to increase white matter, consistent with the literature showing that omega-3 fatty acids promote myelination. We further identified a multiregional pattern of CO activity discriminating omega-3 fatty acid -deficient brains from omega-3 fatty acid -supplemented brains. These findings suggest that omega-3 fatty acid deficiency causes widespread disruption in the communication between brain regions, potentially mediated by decreased myelination. We are currently working to determine if myelination is affected and how. In addition, we hope to expand our work to study the impact of diet on cognition and anxiety in pregnant and peripartum women in the near future.
