Biographical Sketch 
Cathy Fuller, Ph.D. (Associate Professor), received her B.Sc. (Hons.) degree from the University of London (1982), and her Ph.D. from the University of Liverpool (1985), in the laboratory of Prof. O.H. Petersen. She was a post-doctoral fellow in the laboratory of Dr. I. Schulz at the Max Planck Institut fur Biophysik (Frankfurt, Germany), from 1985-1988. She joined the Dept. of Physiology and Biophysics as a post-doctoral fellow in the laboratory of Dr. Dale J. Benos in 1988. She joined the faculty of the department in 1995.

Research/Clinical Interest
Title
ENaC/ASIC Ion Channels;
Description
My lab is interested in the molecular mechanisms underlying the function of epithelial and astrocyte Na+ channels. These cell membrane proteins have important roles to play in the regulation of whole-body salt and water homeostasis, as well as in cell migration and proliferation in disease states such as cancer and renal disease. Current projects in the lab include analysis of ASIC/ENaC family members and their interaction with MAPK/ERK signaling pathways with relevance to migration and proliferation in gliomas, trafficking of these channel subunits in gliomas and their role in lipid rafts, and the role of a novel ENaC/ASIC chnnel in polycystic kidney disease. We use techniques such as fluorescence imaging, RT-PCR, site-directed mutagenesis and electrophysiology.
