mortality/aging
• homozygous mice were produced from intercrossed heterozygotes at a slightly less than expected frequency (16% as opposed to 25%)
|
adipose tissue
• body fat was normal at 10 weeks of age while males became leaner as they aged
• females continued to have a normal body fat content at all ages
• both sexes remained lean on a high fat diet
|
growth/size/body
• 15-25% lighter than normal before weaning
• females are about 10% lighter than normal as adults while males become 30% ligher than normal by 18 weeks of age
|
homeostasis/metabolism
• less than normal levels of insulin are produced during glucose tolerance tests
|
• hypersensitive to insulin
• sensitivity increasing with age
