The overall goal of research in this laboratory is to understand the mechanisms whereby neuronal precursors differentiate into mature functional neurons. To this end, we use the rat PC12 pheochromocytoma cell line developed in this laboratory as a model system to study the mechanism of action of nerve growth factor (NGF) and the steps that lead to neuronal differentiation. Among current projects in the laboratory are those addressing the following questions: 1) What is the essential property of the high-affinity NGF receptor that permits it to mediate the functional activities of NGF and how is this receptor different from the low-affinity, non-functional NGF receptor? 2) What is the transductional mechanism by which NGF receptor occupancy leads to subsequent response? 3) What are the steps beyond immediate transduction that lead to NGF mechanisms? 4) What is the mechanism by which NGF regulates growth cone motility? What are the molecules involved in this effect? 5) What genes are regulated by NGF? By what pathways are they regulated? 6) What are the mechanism by which NGF promotes the initiation and regeneration of neurites; specifically, what is the role of specific cytoskeleton proteins in this process? 7) How do NGF and other neuronotrophic substances maintain cell survival? 8) How do such agents regulate cell proliferation?
