| Outline of Final Research Achievements |
For a treatment strategy for progressive sensorineural hearing loss in Xeroderma pigmentosum (XP), we evaluated a vulnerability of inner ears in XP complementation group A (XPA) model mice morphologically and physiologically. In auditory brainstem response, a hearing threshold of XPA model mice elevated higher than that of control group. In microscopic observation of sacrificed cochlear section, ganglion spiral cochlear cells decreased in XPA model mice. This is a first report on fragile inner ear in XPA model mice, therefore it becomes a cornerstone of inquisition of pathological condition and treatments of progressive sensorineural hearing loss in XP in the future.
