homeostasis/metabolism
• despite a 1.4-fold increase in insulin content, islets exhibit reduced insulin secretion compared with wild-type cells
• GIP (gastric inhibitory polypeptide)- and 8-bromo-cAMP-potentiated insulin secretion is reduced compared to in similarly treated wild-type cells
|
• in fasting mice
|
• following glucose administration
|
• following insulin administration
|
• following insulin administration
|
• following glucose administration
|
• basal and hypoglycemia-induced
|
endocrine/exocrine glands
• beta cells contain fewer docked insulin granules than in wild-type cells
• insulin granule fusion events caused by potassium ion stimulation are decreased compared to in similarly treated wild-type cells
• beta cells fail to exhibit voltage dependent inactivation of voltage-dependent calcium ion channel currents unlike wild-type mice
