    Molecular Regulation of Programmed Cell Death and Oncogenesis

    My lab is interested in the regulation of apoptosis and cancer by the Bcl-2 family of proteins. The Bcl-2 family members are central regulators of cell death as they can block or delay apoptosis after nearly all apoptotic stimuli. The Bcl-2 family contains homologous members that have both anti-apoptotic (e.g. Bcl-2, Bcl-x) as well as pro-apoptotic (e.g. Bax, Bak) activity. I have used both transgenic and knockout models to study the regulation of cell death by Bax. The laboratory is also focused on the role for Bax in oncogenesis and hematopoiesis. Of particular interest are recent data supporting an important role for Bax in increasing oxidative stress, chromosome instability and contributing to oncogenesis. One important goal of the lab is to identify the molecular mechanism by which both Bcl-2 and Bax regulate cellular proliferation and contribute to oncogenesis. More recently, the lab has initiated studies examining the role of mitophagy in general and Beclin and Parkin specifically in the formation and the development of cancer.
