Cell Volume and Sodium Content in Rat Kidney Collecting Duct Principal Cells During Hypotonic Shock
The purpose of this study was to investigate the time course of the volume-regulatory response and intracellular sodium concentration ([Na(+)](i)) in the principal cells of rat kidney outer medulla collecting duct (OMCD) epithelia during acute swelling in hypotonic medium. Hypotonic shock was created by PBS diluted with 50% of water. Changes in cell volume were measured with calcein quenching m...
متن کاملExtracellular hypotonicity increases Na,K-ATPase cell surface expression via enhanced Na+ influx in cultured renal collecting duct cells.
In the renal collecting duct (CD), the Na,K-ATPase, which provides the driving force for Na+ absorption, is under tight multifactorial control. Because CD cells are physiologically exposed to variations of interstitial and tubular fluid osmolarities, the effects of extracellular anisotonicity on Na,K-ATPase cell surface expression were studied. Results show that hypotonic conditions increased, ...

متن کاملAltered collecting duct adenylyl cyclase content in collecting duct endothelin-1 knockout mice
BACKGROUND Endothelin-1 (ET-1) inhibition of vasopressin (AVP)-stimulated water reabsorption by the inner medullary collecting duct (IMCD) is associated with reduced cAMP accumulation. To determine the effect of ET-1 deficiency, AVP-stimulated cAMP responsiveness was assessed in IMCD from mice with collecting duct-specific deletion of ET-1 (CD ET-1 KO) and from control animals. METHODS Cyclic...
