| Outline of Final Research Achievements |
We performed transuterine Dach1 targeted shRNA(shRNA-Dach1) gene transfer into the otocyst of wild-type mice to generate the inner ear specific Dach1 knockdown mice. Reporter gene (eGFP) expressed in the treated ear at embryonic day 15 (E15) and E18. No expression of Dach1 mRNA observed in the treated inner ear at E15 and E18. Pax6 and Igf1 mRNA expression reduced in the treated side at E15.
At postnatal day 30 (P30), stria vascularis was thinned in the shRNA-Dach1 knockdown mice compared to wild-type mice.
