| Outline of Final Research Achievements |
To elucidate the function of CASK in the inner ear, a CASK conditional knockout (cKO) mouse was analyzed. The analysis revealed that the number of the type I and II neuronal cells in the spiral ganglion neurons was greatly reduced. The functional analysis of the inner ear of CASK cKO mouse also supported the idea of disfunction of spiral ganglion neurons. Together with these results it is suggested that CASK expresses in the spiral ganglion neurons and has a critical role in maintaining these cells.
