phenotype observed in females
phenotype observed in males
N normal phenotype
endocrine/exocrine glands
• abnormally large islets with pleomorphic cells of variable size and shape are seen at 20 weeks of age
• 6 of 33 homozygous floxed mutants had adenomas by the date of the scheduled autopsy and tumor incidence in homozygous mutants correlates to the level of Cre expression for the different cre transgenes
• a mild sex bias is seen with 3 of 12 virgin females developing adenomas compared to 3 of 21 males
• adenomas are detected by 44 weeks of age

homeostasis/metabolism
• fasting blood glucose levels are decreased
• fasting serum insulin levels are increased
