Research Topics

The Secretory Mechanisms and Dysfunction Section investigates the molecular nature and function of the ion transport mechanisms involved in the fluid and electrolyte secretion process in the exocrine salivary gland.  We are probing the structure-function relationships of cotransporter, exchanger and channel proteins using a combination of molecular biology, gene modification, proteomics and functional studies in mouse and human salivary glands.  A high-throughput approach is being used to catalogue the human saliva proteome, to identify salivary biomarkers for human diseases, and to compile a comprehensive list of the plasma membrane proteins expressed in salivary glands.

Biography

James Melvin, NIDCR Clinical Director, received his D.D.S. from Case Western Reserve University, a Ph.D. in neurobiology and anatomy from the University of Rochester, and did his postdoctoral training in NIDCR's (then) Clinical Investigation and Patient Care Branch. A former director of the Center for Oral Biology and Professor of Pharmacology and Physiology at the University of Rochester, Dr. Melvin has made numerous contributions to the field of salivary gland physiology and played a key role in the research consortium that decoded the saliva proteome. He directed a number of Ruth L. Kirschstein Institutional National Research Award programs at the pre-doctoral, doctoral and postdoctoral level.
