The Laboratory of Chemoprevention implements a program of research focused broadly on the role of the peptide growth factor, transforming growth factor(TGF)-beta, in homeostasis and pathophysiology, especially carcinogenesis and chemoprevention.

A chemoprevention trial is a type of clinical trial, which is a research study conducted with people. In a cancer chemoprevention trial, natural or laboratory-made substances are tested to see if they prevent cancer. The people who participate in such a study are healthy or are at risk of developing cancer, or in some studies, people who have been diagnosed with cancer and are at risk of developing a second cancer
