Description of Research Expertise

Research Interest:

My research mainly focused on fuel metabolism in islets and regulation of insulin secretion in congenital hyperinsulinism (HI), a group of disorders that cause hypoglycemia in infants and children. My work has involved characterizing most of the known disease models of HI, including glutamate dehydrogenase transgenic mice, sulfonylurea receptor 1 knockout mice, and short-chain 3-hydroxy fatty acyl-CoA dehydrogenase knockout mice. Recently, I have extended these studies of animal models to examine the role of amino acids in regulation of insulin and glucagon secretion by islets from normal and type 2 diabetic humans.


Islets function evaluation: 1) Islets isolation and function studies by batch incubation in 96 well “high-throughput” format and by islets perifusions. 2) Measurement of intracellular calcium in perifused whole islets or dispersed islet cell by duel wave length florescence microscopy.
Fuel Metabolism: 1) Stable isotope tracing: 13C and 15N tracing in isolated islets to study metabolic fluxes from glucose or amino acid; 2)ATP and ATP/ADP ratio measurement to evaluate fuel metabolism.
Gene expression: study gene expression by qPCR in whole islets or in purified beta-cell by cell sorting.
