Research Abstract

About 30% of the 120 million people who suffer from congenital (early-onset) hearing loss are syndromic, and the remaining 70% are non-syndromic worldwide. At present, however, no effective therapies for deafness have been established except for cochlear implantation. We have recently shown that complete impairment of Y1062-phoshorylation in c-Ret causes congenital deafness in homozygous c-Ret Y1062F knock-in mice (c-Ret-KIY1062F/Y1062F-mice). On the other hand, there is no information about the relevance between c-Ret and age-related hearing loss. In this study, we used heterozygous c-Ret Y1062F knock-in mice (c-Ret-KIY1062F/+-mice) in order to analyze whether partial impairment of Y1062-phoshorylation inc-Ret causes age-related hearing loss. This study suggests that partial impairment of c-Ret causesage-related hearing loss involving neurodegeneration of spiral ganglion neurons in mice.
