| Summary: | Summary: Mouse hyperglycemia model and islet function assessment are essential in diabetes research. Here, we provide a protocol to evaluate glucose homeostasis and islet functions in diabetic mice and isolated islets. We describe steps for establishing type 1 and 2 diabetes, glucose tolerance test, insulin tolerance test, glucose stimulated insulin secretion (GSIS) assay, and histological analysis for islet number and insulin expression in vivo. We then detail islet isolation, islet GSIS, β-cell proliferation, apoptosis, and programming assays ex vivo.For complete details on the use and execution of this protocol, please refer to Zhang et al. (2022).1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
