Research/Clinical Interest
Title
Cellular and Molecular Physiology of Acid-base Transporters and pH Regulation
Description
My laboratory is interested in the cellular and molecular physiology of intracellular pH (pHi) regulation and acid-base transport in tissues such as the brain, heart, and kidney. We are also interested in how acid-base transporters, as well as ion channels such as the epithelial Na+ channel (ENaC) contribute to Na+ hyperabsorption in mouse models of autosomal recessive polycystic kidney disease (ARPKD). Transporters that move acids (e.g., H+) or bases (e.g., bicarbonate or HCO3– ) across the plasma membrane of cells contribute to many cellular processes, including the regulation of pHi, secretion or reabsorption of ions, and modulation of neuronal activity. Some of these transporters include Na-H exchangers, electrogenic and electroneutral Na/HCO3 cotransporters, and Na-dependent and -independent Cl-HCO3 exchangers. In our cellular studies, we use fluorescence approaches with ion-sensitive dyes and electrophysiological techniques (e.g., patch-clamping) to identify and characterize the function and regulation of ion channels and transporters involved in ion movement and acid-base transport across plasma membranes. In our neuroscience research, we are also interested in the effects of pHi changes and transporter activity on neuronal firing and synaptic transmission. The laboratory is also elucidating the molecular nature of Na/bicarbonate cotransporters (NBCs) and related proteins present in brain, heart, and kidney. The laboratory is characterizing structure-function relationships, ion translocation, and regulation of the cloned proteins expressed in either frog oocytes impaled with microelectrodes, or transfected mammalian cells loaded with ion-sensitive dyes. Electrophysiological recordings from excised membrane patches from oocytes enable us to identify and characterize intracellular regulators of NBC activity. The results from our cellular and molecular studies will enhance our understanding of the physiology of pHi regulation and the biophysics of bicarbonate transport, as well as elucidate the contribution of acid-base transporters and ion channels to polycystic kidney disease.
