| Research Abstract |
In the present study, several types of anion channels, which are involved in cell death-survival switching, were investigated, and the followings were elucidated: 1. Reactive oxygen species (ROS) or dissociation of ABCF2 and protein tyrosine dephosporylation are involved in activation of VSOR and Maxi-Cl, respectively. 2. Three and two candidates were selected as the candidate molecules for VSOR and Maxi-Cl, respectively. 3. Rescue from apoptotic, necrotic and ischemic cell death is induced by regulating the activities of VSOR, ASOR and CFTR anion channels.
