Elizabeth Smith, Ph.D.
Research Assistant Professor of Medicine
Description of Research
Dr. Smith’s research interests include: 1) growth factor-dependent mitogenesis in tumor development, specifically MAPK (ERK1/2) signaling and regulation in primary (non-transformed normal) epithelial and ES cells and the disregulation of the kinase in ovarian and breast epithelial-derived cancers; 2) Disabled-2 function in tumor suppression. Dab2, an adaptor protein involved in clathrin-coated vesicle endocytosis and sorting, was first identified as a mitogen-stimulated phosphoprotein differentially lost in ovarian cancer. Dr. Smith’s goal is to understand the function of Dab2 related to ovarian tumor development and in epithelial-like differentiation; 3) Cyclooxygenase involvement in reducing the risk of ovarian cancer. Dr. Smith’s work has used a menopause-like mouse model to investigate the utility and mechanism of COX inhibition in reducing the risk of ovarian carcinoma.
