N normal phenotype
homeostasis/metabolism
• double mutants have improved blood glucose levels compared to Pdk1-deficient mice; glucose levels of 200-300 mg/dl are maintained in double mutants at 20-24 weeks
• plasma insulin level is significantly higher in double mutants compared to Pdk1-deficient mice

endocrine/exocrine glands
• Foxo-haploinsufficiency results in a significant increase in beta cell number in double mutants
• insulin content of the pancreas in double mutant mice is 6-fold higher than in Pdk1-deficient mice; number of proliferating beta cells is much greater in double mutants compared to Pdk1-null mice
