mortality/aging
|
• mice die within 2 days of birth unless normal littermates are removed thereby reducing competition for milk
• however, if normal littermates are removed mice survive into adulthood
|
taste/olfaction
|
• olfactory neurons are not responsive to forskolin
|
growth/size/body
|
• mice fail to thrive after birth
|
nervous system
|
• olfactory neurons are not responsive to forskolin
|
nervous system
|
• Hyb B and Hyb D axons segregate into separate into separate compartments within the same glomeruli
|
nervous system
|
• mice have more and shorter olfactory neuron axonal projections per bulb (2-9 Olfr160+ glomeruli per bulb with a mean length of 41um compared to 2-4 Olfr160+ glomeruli per bulb with a mean length of 72 um in wild-type mice)
• at day 7, Olfr160+ axons are often observed to enter inappropriate glomeruli or continue to grow past the glomerulus layer into the deep layers of the bulb
