homeostasis/metabolism
• homozygotes develop into adulthood without apparent growth defects but exhibit a mild but significant fasting hyperglycemia, which is more pronounced during fed states
• homozygotes develop inadequate compensatory hyperinsulinemia
• in response to oral glucose load, 2-mo-old homozygotes display a mild glucose intolerance, with increased blood glucose levels at all time points measured
• in response to i.p. administration of insulin, homozygotes display significantly elevated blood glucose levels relative to wild-type mice at all time points measured (at 60 min; 70.8 7.9 mg/dl vs 22.3 1.1 mg/dl, respectively)
• in euglycemic-hyperinsulinemic clamp expts, homozygotes exhibit peripheral insulin resistance along with complete failure of insulin to suppress hepatic glucose output
• however, circulating free fatty acid concentrations remain normal

muscle
• insulin-stimulated hexose uptake into the glycolytic extensor digitorum longus (EDL) muscle is severely blunted in the presence of 0.33 nM insulin; however, no impairment is noted upon exposure of the mutant EDL to a higher insulin concentration (13.3 nM)
• insulin-stimulated deoxyglucose uptake into the oxidative soleus muscle is not significantly impaired at either an intermediate or maximal concentration of insulin

endocrine/exocrine glands
• pancreata from 2- to 3-month-old male homozygotes respond to insulin resistance with an increase in islet mass (~4-fold) and number (~2-fold) relative to wild-type mice

adipose tissue
• in euglycemic-hyperinsulinemic clamp studies, insulin-stimulated hexose uptake is mildly impaired in mutant adipocytes

N
• the liver phenotype observed in single Pten mutants is significantly reduced, with liver weights, triglyceride levels in the liver and fatty liver almost similar to controls
• progenitor cell accumulation in the periductal region of livers occurs later than in single conditional Pten homozygotes, when injury conditions are already present
• mice do not show development of steatosis compared to single conditional Pten homozygotes

neoplasm
• mice exhibit a 6-month delay in liver tumor onset compared to conditional Pten homozygotes
• no mice develop liver tumors between 9 and 12 months of age and 25% of mice older than 12 months develop liver nodules
• however, treatment of 3 month old mice with 3,5-dietoxycarbonyl-1,4 dihydrocollidine (DDC) to induce liver injury leads to massive expansion of hepatic progenitors and development of premalignant lesions
