| Outline of Final Research Achievements |
This study was initiated to check whether the onset of hearing loss can be prevented by inhibiting the expression of the causative protein of DNFA9 in the adult onset-type hereditary hearing loss. First, it is necessary to obtain cells, which are stably expressing Cochlin. However, since there are no cells in the commercial-use cell lines expressing Cochlin, isolated fibroblasts from the inner ear of mice and immortalized cell lines were used to attempt forced expression of COCH mRNA using an expression vector - but cells which stably express Cochlin were unable to be obtained. In addition, as a preliminary experiment, miRNA that could inhibit Cochlin was searched for in miRNA in the human inner ear but was not confirmed.
