• gut motility is significantly decreased in females but at later age than males and with less severity
|
|

• male castration decreases median survival by 10 days
|
|
• Background Sensitivity: death occurs at a median of 108 days in males
• Background Sensitivity: death occurs at a median of 185 days in females
|
|
• ganglions in the superior mesentery appear smaller than control ganglions
• ganglions exhibit an increased percentage of condensed nuclei
|
|
• decreased AChE staining in the ganglion and intermodal strands of the myenteric plexus of the colon
|
|
• 80% decrease in the number of neurons per ganglion in the myenteric plexus of the colon, but not the duodenum, of 90-150 day old mice
|
|
|
• reactive astrocytosis observed in spinal cord lumbar sections from 80 day old males
|
|
|
• the large motor neurons of some males exhibit abnormally shaped nuclei
|
|
|
• small, but significant decrease in axon number and diameter in the sensory branch of the femoral nerve in 3 and 5 month old males
|
|
|
• some motor neurons have ubiquitin-positive cytoplasmic inclusions
|
|
• late onset kyphosis occurs suddenly and progresses rapidly especially in males
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
|
• Background Sensitivity: survival in F1 males is increased by more than 340 days as compared to males on the C57BL/6J background
|
|
• all F1 mice die with visible signs of gut pathology similar to mice on the C57BL/6J background

|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• average survival is 154 days; at end-stage, mice die spontaneously or are euthanized when they lose righting reflex or can no longer obtain food and water
|
|
• mice begin losing weight around 4.5 months of age
|
|
• at 3-4 months mice develop abnormal gait; around 4.5 months, mice exhibit a "swimming" gait when they lose ability to support their body weight but still use their limbs for propulsion to slide on their stomachs
|
|
• activation of astrocytes is detected in layer 5 with reactive astrocytosis seen around degenerating neurons
|
|
• late-stage mice have cytoplasmic accumulation of ubiquinated proteins in neurons of cortical layer 5; these neurons are prominent in the motor cortex and are also present in orbital, cingulated, sensory and other cortical regions
• no ubiquinated protein aggregates are observed in the caudate/putamen, substantia nigra, thalamus or other structures at any stage
|
|
• neuron loss in cortical layer 5
|
|
• fewer axons are observed in the lower thoracic spinal cord with numerous degenerating axons being seen in dorsal corticospinal tract and lateral columns
• femoral motor and sensory nerves shows loss of axons with ongoing axonal degeneration in the motor branch
|
|
• fewer axons are observed in the lower thoracic spinal cord with numerous degenerating axons being seen in dorsal corticospinal tract and lateral columns
|
|
• in end-stage mice, about a 20% loss of spinal motor neurons is observed
|
|
• presence of ubiquitinated protein accumulations is detected preferentially in large neurons of the dorsal horn as well as scattered interneurons
|
|
• end-stage mice have scattered and grouped atrophic muscle fibers, characteristic of muscle denervation
|
|
• atrophic muscle fibers are observed in end-stage mice
|
|
• electromyography in end-stage mice shows numerous fibrillation potentials indicative of loss of muscle fiber innervation and fasciculations, which are spontaneous firing of motor units often seen with human motor neuron diseases; in presymptomatic and early-stage mice, electromyography is normal
|
|
• around 4.5 months, mice can no longer support their body weight
