| Outline of Final Research Achievements |
To clarify the mechanism of ototoxicity with aminoglycoside antibiotice (AG), we have established the experiment systems of ototoxicity for MtDNA1555AG iPSC. In the recent technology, it is impossible to make transgenic mouse for this mitochondrial SNP mutation.
Compared with hair cells, most cells don't have any transport systems for taking AG into the cells. We therefore use nanocarrier encapsulated AG. When we use this nanocarrier for Hela cell line, only mitochondria specific carrier showed cell death dose-dependently. We established patient drived iPSC cell lines and characterized them. We further optimized the composition of nanocarrier for iPSC, and Ag encapsulated nanocarrier are now preparing.
