The general focus of our lab's research is on  the question "What controls stem and cancer cell behavior?" We are interested in answering this question about stem cells both during normal embryonic development but also during healing and regeneration. Further, we are analyzing how this control system goes awry during diseases such as developmental disorders and cancer. Although our lab is mostly focused on studying neural stem cells we are also beginning to examine other types such as embryonic stem cells. One important reason for studying a variety of types of stem cells is that it enables us to ask whether the same types of control system are at work in different stem cells. So far we have found that a particular group of proteins called the Myc family appear to be master regulators of stem cell function. These Myc proteins are not only of critical importance for the ability of stem cells to do their normal "job" but also when the Myc genes are present at too high a concentration in stem cells they cause many human cancers. However we don't have a clear understanding of how Myc genes control the normal function of stem cells in development and regeneration nor how an excess of Myc leads to cancer. Therefore studying Myc's function in stem cells may provide critical clues as to how stem cells can be used in regenerative medicine as well as how to do our best to avoid cancer as a side effect from stem cell based regenerative medicine. Finally, these studies of Myc should also help us to better understand human cancer in a more general sense, hopefully moving us one step closer to a cure.
