Research Interests

Our long-term research goal is to understand at a molecular level how ion channels are modulated by novel mechanisms and how we may manipulate channel regulation to treat diseases and protect cells from ischemic insults. In particular, we are interested in the ATP-sensitive potassium (KATP) channel, a high-fidelity metabolic sensor which sets membrane excitability to match cellular energy demand. Defects of KATP channel functionality are associated with diseases or pathophysiological states such as hypertension, vasospasm, diabetes mellitus, congenital hyperinsulinism, seizure, dilated cardiomyopathy, and ischemic/reperfusion injury. Our current work focuses on delineating the molecular mechanism and intracellular signaling pathway responsible for functional regulation of KATP channels by cyclic-nucleotide-dependent kinases and calcium. Other lines of research in my laboratory include studies of the role of KATP channels in ischemic preconditioning and regulation of GABA(A) receptors by novel messengers.
