endocrine/exocrine glands

decreased pancreatic beta cell mass ( J:286108 )

• when mice are fed a high-fat diet compared with controls

small pancreatic islets ( J:286108 )

• when mice are fed a high-fat diet compared with controls

decreased insulin secretion ( J:286108 )

• 3-fold from isolated islets treated with glucose

• however, response to arginine or KCl is normal and first-phase secretion is normal

homeostasis/metabolism

decreased insulin secretion ( J:286108 )

• 3-fold from isolated islets treated with glucose

• however, response to arginine or KCl is normal and first-phase secretion is normal

decreased susceptibility to diet-induced obesity ( J:286108 )

• when mice are fed a high-fat diet despite comparable food intake

decreased fasting circulating glucose level ( J:286108 )

• mice fed a high-fat diet exhibit reduced fasting glucose levels compared with control mice fed the same diet

decreased circulating insulin level ( J:286108 )

• mice fed a high-fat diet exhibit reduced insulin levels compared with control mice fed the same diet

improved glucose tolerance ( J:286108 )

• when mice are fed a high-fat diet compared with controls

increased insulin sensitivity ( J:286108 )

• when mice are fed a high-fat diet compared with controls

growth/size/body

decreased susceptibility to diet-induced obesity ( J:286108 )

• when mice are fed a high-fat diet despite comparable food intake
