growth/size/body
• the body weight of adult mice with this transgene is ~10% greater than that of wild-type controls
|
homeostasis/metabolism
• fasting blood glucose is lower in 2 month old mice with this transgene than in wild-type controls (80 +/- 18 mg/dl vs. 105 +/- 33 mg/dl)
|
• fasting plasma insulin is significantly lower in mice with this transgene than in wild-type controls
• insulin levels of transgenic mice are significantly lower than those of wild-type controls 30 min after a glucose challenge
• insulin levels are lower in transgenic than in wild-type mice even when the glucose level has been clamped at 10mM for 120 min
|
• 8-10 week old mice with this transgene exhibit significantly lower plasma glucose levels than wild-type controls at all time points of a glucose tolerance test
|
• mice with this transgene exhibit significantly greater glucose clearance than wild-type controls in an insulin tolerance test
