behavior/neurological
N |

• mice do not exhibit evidence of motor difficulties
• mice do not differ from wild-type in rotarod performance or forelimb/hindlimb grip strength
|
growth/size/body
N |
• mice do not differ from wild-type in body weight
|
mortality/aging
N |

|
nervous system
N |
• number of inclusions is similar to wild-type
|
• neuronal loss is observed in the dentate gyrus at both 3 and 8 months
• no loss is observed in the CA1 region
|
astrocytosis
(
J:239510
)
• minimal astrocytosis is observed in 8 month old, but not 1, month old mice
|
• loss of corticospinal neurons at 3 and 8 months of age
• no lower motor neuron loss observed
|
• increase in number of small-caliber axons as compared to large-caliber axons in gastrocnemius muscle, however, overall number of large-caliber axons is unchanged
