Anthony J. Capobianco, Ph.D.
Professor of Surgery; Director, Molecular Oncology Research Program, Division of Surgical Oncology
Description of Research
Dr. Capobianco's laboratory is directed toward the elucidation of the Notch signaling pathway and how deregulation of this pathway leads to neoplasia. Research in his lab is centered on three main projects. The most important project in the lab is the dissection of the biochemical signaling mechanism of Notchic proteins. Dr. Capobianco and his colleagues have discovered that Notch exists in the nucleus in a large multi-component complex, and are working to define the role of this complex in Notch signaling. A second major area of research is related to the function of DSL proteins (Notch ligands) in Notch signaling.
Dr. Capobianco's lab has discovered that Jagged1, in addition to signaling through Notch, can signal via a PDZ-dependent mechanism. His studies provide direct evidence that the Notch/DSL signaling pathway is, in fact, bi-directional. The third area of research is in mouse models of human cancer. Dr. Capobianco's lab has developed several mouse models and tools to investigate the role of Notch and Jagged in human neoplastic disease.
