Abstract

The Goto-Kakizaki (GK) rat is a model of type 2 diabetes mellitus, produced originally by selective inbreeding for a hyperglycemic trait. These rats are characterized as having insulin resistance and an insulin secretory defect. Pancreatic islets from these mice show abnormal morphology in the distribution of glucagon-secreting α cells and insulin-secreting β cells, which may affect paracrine functions involved in the secretory response. This chapter describes the characterization of GK rat islets using immunofluorescence microscopy and Western blot analyses to demonstrate the effects on islet architecture and how this translates to changes in expression of predominant islet proteins.
