Find Mice

Using the International Mouse Strain Resource (IMSR)
Mouse lines carrying:
Pip4k2b^{Gt(Betageo)1Lca} mutation (0 available); any Pip4k2b mutation (34 available)

♀	phenotype observed in females
♂	phenotype observed in males
N	normal phenotype

mortality/aging

perinatal lethality, incomplete penetrance ( J:91023 )

• homozygous mice were produced from intercrossed heterozygotes at a slightly less than expected frequency (16% as opposed to 25%)

adipose tissue

decreased total body fat amount ( J:91023 )

• 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

decreased body weight ( J:91023 )

• 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

abnormal circulating insulin level ( J:91023 )

• less than normal levels of insulin are produced during glucose tolerance tests

increased insulin sensitivity ( J:91023 )

• hypersensitive to insulin

• sensitivity increasing with age

limbs/digits/tail

short femur ( J:91023 )

• at 10 weeks of age, femurs are 7.3% +/- 0.7% shorter than controls

skeleton

short femur ( J:91023 )

• at 10 weeks of age, femurs are 7.3% +/- 0.7% shorter than controls

abnormal vertebral spinous process morphology ( J:91023 )

• spines were shorter than normal

decreased bone mineral density ( J:91023 )

• 10 week old male mice have 9.5% lower bone mineral density than controls
