Nutrition & Cancer Biology

Mission

The Nutrition and Cancer Biology laboratory examines how dietary carotenoids which are concentrated in vegetables (e.g., tomatoes, carrots, broccoli and spinach) and fruits (e.g., orange, watermelon, and pink fruit), vitamin A, vitamin D and fish oil modify molecular and genetic pathways which alter the development of cancers, such as those of the lung, colon, and liver. This laboratory also examines how this response is modified by other exogenous factors (e.g., tobacco smoking, chronic alcohol consumption, high fat diet and chemical carcinogen exposure).

Lab Objectives

1. Determine whether high fat diet induced non-alcoholic steatohepatitis is a promoting factor in hepatic carcinogenesis.

2. Determine whether dietary lycopene will protect against high fat diet promoted liver cancer development.
