homeostasis/metabolism
decreased insulin secretion ( J:129643 )
• insulin release following treatment with oxotremorine-M is reduced 50% compared to from wild-type islet cells
• however, total insulin content is normal
impaired glucose tolerance ( J:129643 )
• following administration of glucose, serum glucose levels are increased and insulin levels are decreased compared to in wild-type mice
• however, insulin sensitivity is normal

endocrine/exocrine glands
decreased insulin secretion ( J:129643 )
• insulin release following treatment with oxotremorine-M is reduced 50% compared to from wild-type islet cells
• however, total insulin content is normal
