Research Abstract

Collaboration with foreign researcher has been proposed to create KCNQ4 knock-out mouse in order to start the microbiological and immunohistochemical experiments initially. However, the proposal was refused. Knock-out mouse of alpha-1D calcium channel which plays an important role in activation of signal transduction of vestibular hair cell, was then carried out. Unfortunately, good yield could not be obtained as planned. Therefore, without any delayed, an alternative project was shifted to focus on the change in numbers and physiology of vestibular hair cell due to ageing by using SAM-P1 and Wister mice in different age (older and young group respectively). So far, physiologically, the gkL channel showed no different in between 2 control young groups (P7~P14). Our next step is by using the physiological fact of these control groups will be compared with the old groups 24-month~36-month -old) and this project is still in progress.
