Research interests 

Dr. Xiang-dong Wang’s Laboratory examines how carotenoids, 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). Several approaches, including animal studies, molecular and cell culture studies, and human translational studies are used to elucidate the molecular mechanisms by which those nutrients prevent cancer development.
