Localization and irregular distribution of Na,K-ATPase in myelin sheath from rat sciatic nerve
(Churchill Livingstone, 2007-06-01)
Sodium, potassium adenosine triphosphatase (Na,K-ATPase) is a membrane-bound enzyme that maintains the Na+ and K+ gradients used in the nervous system for generation and transmission of bioelectricity. Recently, its activity ...
Acid-base transport by the renal distal nephron
(WICHTIG EDITORE, 2010)
The functional versatility of the distal nephron is mainly due to the large cytological heterogeneity of the segment. Part of Na(+) uptake by distal tubules is dependent on Na(+)/H(+). exchanger 2 (NHE2), implicating a ...
Age-related changes in cerebellar phosphatase-1 reduce Na,K-ATPase activity
(ELSEVIER SCIENCE INC, 2008)
We evaluated whether changes in protein content and activity of PP-1 and PP-2A were the mechanism underneath the basal age-related reduction in alpha(2/3)-Na,K-ATPase activity in rats cerebella and whether this occurred ...
Na+/K+-ATPase stabilization by Hsp70 in the outer stripe of the outer medulla in rats during recovery from a low-protein diet
(Springer, 2008-02-19)
A low-protein (LP) diet induces injury from energy depletion in renal epithelial cells. Overexpression of heat-shock proteins has been implicated in the restoration of the cytoskeletal anchorage of Na+/K+-ATPase. We tested ...
Effect of Chronic Renal Failure on NaK-ATPase A1 and a2 mRNA Transcription in Rat Skeletal Muscle
(1991)
Previous studies have suggested that an alteration in the expression
of the NaK-ATPase of muscle may be an important
determinant of enhanced insulin sensitivity in chronic renal failure.
Therefore, in the present studies ...
Changes in sodium, potassium-ATPase induced by repeated fencamfamine: the roles of cyclic AMP-dependent protein kinase and the nitric oxide-cyclic GMP pathway
(Elsevier B.V., 2003-12-01)
Fencamfamine (FCF) is an indirect dopamine agent with effects similar to amphetamine and cocaine. In the present study, we investigate changes in Na,K-ATPase, cyclic AMP-dependent protein kinase (PKA) and nitric oxide ...
Modulation of (Na,K)-ATPase activity by membrane fatty acid composition: Therapeutic implications in human hypertension
(2014)
Oxidative stress (OS) plays a key role in the pathophysiology of essential hypertension and is associated with changes in the cell membrane fatty acid composition and fluidity. As (Na,K)-ATPase is modulated by the surrounding ...
Effects of ammonia stress in the Amazon river shrimp Macrobrachium amazonicum (Decapoda, Palaemonidae)
(Elsevier B.V., 2016-01-01)
We evaluate the effects of total ammonia nitrogen-N (TAN) exposure for 72 h on (Na+,K+)- and V(H+)-ATPase activities and on their subunit expressions in gills of the diadromous freshwater shrimp Macrobrachium amazonicum. ...
