Endocrine Pharmacology

The body employs an array of hormones to regulate internal temperature, metabolism, growth, and responses to stress and injury. Research within Michigan Pharmacology investigates the mechanisms underlying: 1) The biogenesis of trafficking organelles and the synthesis, storage, and secretion of hormones from the adrenal medulla and endocrine pancreas; 2) Steroid biosynthesis, with an emphasis on the mechanistic enzymology of steroidogenic cytochrome P450s and dehydrogenases/reductases. The translational application of this research leverages our expertise in steroid mass spectrometry and use of multi-steroid panels to profile steroid hormones, precursors, and metabolite in a single assay; and, 3) Pulsatile insulin secretion from pancreatic islets and stimulus secretion coupling in pancreatic beta cell, with an emphasis on dysfunctional secretion in type 1 and type 2 diabetes.
