Research Abstract |
Bone diseases are serious problem in an aged society and their treatment is necessary for maintaining QOL. To prevent bone diseases, we have done the study of effects of ion channels and membrane potential in bone. To investigate the signaling mechanism via ion channel and receptor, we examined the function of bone cells by light-sensitive ion channel and pump. The light-gated ion channels and pump were transfected into bone cells and then the role of membrane potential on those cells were investigated. Further, based on their results, we identified bone remodeling-related novel ion channels. In summary, our results indicate that membrane potential regulate bone cell function and bone remodeling-related novel ion channels are important for osteoclastic functions.
