Different stoichiometries are observed between alpha and beta subunits of Na,K-ATPase that depend on the method employed to solubilize and purify the enzyme. It is not known whether this variability is due to loss of ...

The present work was designed to study Na+ K+ ATPase alpha1-subunit phosphorylation in rats with chronic renal failure (CRF) in comparison with normal rats. Na+ K+ ATPase alpha1-subunit phosphorylation degree was measured ...

Na+/K+ pump or sodium- and potassium-activated adenosine 5’-triphosphatase (Na+, K+-ATPase), its enzymatic version, is a crucial protein responsible for the electrochemical gradient across the cell membranes. It is an ion ...

Background-Acute elevation of left atrial pressure (LAP) increases extravascular water and impairs active Na+ transport in rat lungs. We have reported that overexpression of Na,K-ATPase subunit genes in the alveolar ...

Diadromous freshwater shrimps are exposed to brackish water both as an obligatory part of their larval life cycle and during adult reproductive migration; their well-developed osmoregulatory ability is crucial to survival ...

Neurotensin is a basic tridecapeptide which can act as a neuromodulator or a neurotransmitter and binds to a group of receptors. Neurotensin is able to inhibit Na+, K+-ATPase activity, an effect blocked by the presence of ...

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. ...

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 ...

In the brain, Na+,K+-ATPase activity is essential for maintaining of the electrochemical gradient underlying the resting potential and release and uptake of neurotransmitters, and a decrease in its activity alters brain ...
