mortality/aging
• mice show reduced life span
|
behavior/neurological
• mice exhibit difficulty in righting themselves
|
trunk curl
(
J:216420
)
• in the trunk curl test, mice do not reach for the horizontal platform when suspended by the tail and tend to curl in toward their abdomen
|
head bobbing

head tossing

hearing/vestibular/ear
• ABR waveform analysis indicates a reduction in the first ABR wave amplitude at 6 and 8 months of age and a reduction in summating potential amplitude at 10 months of age, indicating a functional disruption in the cochlear synapse and/or cochlear nerve
|
• mice exhibit a progressive increase in ABR threshold
|
• sensorineural hearing loss that is temporally correlated with tumorigenesis
|
nervous system
• most mice show only multiple large schwannomas, but 5 of 16 mice show tumor lesions consistent with malignant peripheral nerve sheath tumors
|
• mice develop slow-growing, low-grade schwannomas that are seen by 5 months of age
• schwannomas are seen in the dorsal root ganglion and proximal spine nerve by 8 months, and in peripheral, cranial, and spinal nerves (such as of the trigeminal and facial nerves) by 10 months
• aberrant Schwann cell growth is seen in cranial nerve VIII proximal to its entry into the inner ear, including tumors in Scarpas ganglion
• all mice exhibit vestibular schwannomas
|
• Schwann cell hyperplasia in the spinal ganglion
|
• by 5 months of age, all mice show enlargement of the dorsal root ganglion
|
• by 5 months of age, all mice show enlargement of the proximal spinal nerve roots
|
neoplasm
• most mice show only multiple large schwannomas, but 5 of 16 mice show tumor lesions consistent with malignant peripheral nerve sheath tumors
|
• mice develop slow-growing, low-grade schwannomas that are seen by 5 months of age
• schwannomas are seen in the dorsal root ganglion and proximal spine nerve by 8 months, and in peripheral, cranial, and spinal nerves (such as of the trigeminal and facial nerves) by 10 months
• aberrant Schwann cell growth is seen in cranial nerve VIII proximal to its entry into the inner ear, including tumors in Scarpas ganglion
• all mice exhibit vestibular schwannomas
