• at 3 and/or 4 months of age, males and female mice show normal body weight and blood glucose levels in the fed and fasted state relative to wild-type littermates
• contrary to the 2-fold reduction in plasma insulin levels reported in non-fasting 16-week-old female and male mice by IKMC, mice of both sexes analyzed at 16 weeks of age in J:287356 show no differences in non-fasting and fasting plasma insulin levels relative to wild-type littermates
• at 17 weeks of age, overnight fasted mice of both sexes show no alterations in glucose sensitivity or insulin response, as determined by an intra-peritoneal glucose tolerance test
• pancreatic islets isolated from overnight fasted 3-month-old males show normal insulin release in response to glucose stimulation with no differences in islet insulin content or Ins2 mRNA levels relative to wild-type islets
