Biography

The long-standing interest of my laboratory is the regulation of signaling pathways, including understanding the molecular mechanisms of action of signaling components in normal biological processes and in disease processes. We are currently focused on understanding the cascade of intracellular events that leads to the activation of Wnt/ß-catenin signaling and the biological role of the Wnt/ß-catenin pathway during embryonic development and in disease. We employ three experimental systems: Xenopus laevis, mice, and cultured cell lines and primary cells. We use these systems to gain information on gene functions with the goal to uncover and characterize biochemical and developmental mechanisms that could ultimately be used to prevent Wnt/beta-catenin deregulation in congenital and adult diseases. Our areas of interest are:

1. To characterize the molecular mechanism leading to activation (stabilization and nuclear translocation) of ß-catenin, the key intracellular Wnt component that is activated in many human tumors

2. To define the role of Wnt/ß-catenin signaling during embryonic development, including its role in dorso-ventral axis formation and organ morphogenesis

3. To determine how deregulation of Wnt/ß-catenin components leads to diseases such as cancer and congenital defects
