High fat diet-induced obesity causes impaired glucose tolerance and insulin secretion in Ghrtm1.1Dlr/Ghrtm1.1Dlr Tg(Ins2-cre)25Mgn/0 mice

endocrine/exocrine glands
• mice fed a high-fat diet exhibit decreased beta cell proliferation compared with wild-type mice
• mice fed a high-fat diet exhibit impaired beta cell hyperplasia compared with similarly treated wild-type mice
• following administration of a glucose bolus, mice exhibit reduced first phase of insulin secretion compared with wild-type mice
• following glucose stimulation in pancreas islets from mice fed a high-fat diet
• however, mice exhibit normal insulin secretion in response to a physiologic (meal) glucose exposure and arginine-stimulated insulin release

homeostasis/metabolism
• following administration of a glucose bolus, mice exhibit reduced first phase of insulin secretion compared with wild-type mice
• following glucose stimulation in pancreas islets from mice fed a high-fat diet
• however, mice exhibit normal insulin secretion in response to a physiologic (meal) glucose exposure and arginine-stimulated insulin release
• during a glucose tolerance test in mice fed a high-fat diet

cellular
• mice fed a high-fat diet exhibit decreased beta cell proliferation compared with wild-type mice
