| Research Abstract |
Aiming at elucidation of molecular regulatory mechanisms underlying the reabsorption of water and electrolytes on the distal tubules and collecting ducts of the nephron, we demonstrated calcineurin is involved in the signaling pathway dictating the angiotensin II-dependent aldosteron secretion. Further, we found that deficiency of the mascurin gene causes depletion of the antidiuretic hormone(vasopressin). Finally, amounts of urine and water intake were increased when a high salt concentration of water was given to the sulfated glycolipid-deficient mice. However expression levels and membrane localizations of aquaporin and Na^+, K^+-ATPase were not deteriorated.
