We are studying how epithelial cells adopt specific characteristics that allow them to function within an organ system. Epithelial cells line the exterior of most organs and are therefore essential for development and normal homeostasis. During development of an organ, cells must respond to signals that direct them to alter their behavior (i.e. movement/migration, division and differentiation). How a cell integrates and responds to these signals is essential to form a functional organ. In our lab, we use the model organism Caenorhabditis elegans to study how specific proteins regulate epithelial cell behavior during development. In particular, we are interested in how epithelial cells adhere to one another and to different protein matrices in their environment and how these connections are regulated during normal organogenesis. We have identified a number of important proteins (including the putative tumor suppressor protein, TES-1) that help epithelial cells move, form strong adhesions with other cells and their environment and adopt unique shapes that allow them to function within an organ. Our research can not only lead us to a deeper understanding of development, but can also shed light on how specific diseases arise. For instance, tumors that arise from epithelial cells constitute over 80% of the malignancies diagnosed each year. The ability of a tumor to form metastases, secondary tumors that enhance the lethality of the disease, depends on the same protein machinery that regulates normal cellular movement, migration and adhesion.
