Outline of Final Research Achievements |
The genome of teleost fishes encodes more than a thousand of membrane transport proteins such as transporters, channels, and pumps. Some of these transporters are expressed in the epithelia of the gill, intestine, and kidney and are responsible for the osmoregulation and the body-fluid homeostasis of teleost fishes in fresh water and seawater environments. However, the activities of these transporters are not well characterized in vitro. In the present study, we analyzed the function of these transporters by using electrophysiological techniques to clarify novel branchial and renal mechanisms for the freshwater and seawater acclimation.
