Sodium-calcium exchange in transverse tubules isolated from frog skeletal muscle
(1989)
Transverse tubule vesicles isolated from frog skeletal muscle display sodium-calcium exchange activity, which was characterized measuring 45Ca influx in vesicles incubated with sodium. The initial rates of exchange varied ...
Sodium deoxycholate inhibits chick duodenal calcium absorption through oxidative stress and apoptosis
(Elsevier Science Inc, 2012-05)
High concentrations of sodium deoxycholate (NaDOC) produce toxic effects. This study explores the effect of a single high concentration of NaDOC on the intestinal Ca2+ absorption and the underlying mechanisms. Chicks were ...
Excitotoxicity as a target against neurodegenerative processes
(Bentham Science Publishers, 2020)
Endothelin-1 stimulates the Na+/Ca2+ exchanger reverse mode through intracellular Na+ (Na+i)-dependent and Na+i-independent pathways
(Lippincott Williams, 2005-02)
This study aimed to explore the signaling pathways involved in the positive inotropic effect (PIE) of low doses of endothelin-1 (ET-1). Cat papillary muscles were used for force and intracellular Na(+) concentration ...
Molecular aspects of intestinal calcium absorption
(W J G Press, 2015-06)
Intestinal Ca2+ absorption is a crucial physiological process for maintaining bone mineralization and Ca2+ homeostasis. It occurs through the transcellular and paracellular pathways. The first route comprises 3 steps: the ...
Biomolecular information, brain activity and cognitive functions
(2007-12-01)
Molecular neurobiology has provided an explanation of mechanisms supporting mental functions as learning, memory, emotion and consciousness. However, an explanatory gap remains between two levels of description: molecular ...

The regulation of NHE₁ and NHE₃ activity by angiotensin II is mediated by the activation of the angiotensin II type I receptor/phospholipase C/calcium/calmodulin pathway in distal nephron cells
(Amsterdam, 2013-12-05)
Angiotensin II (Ang II), acting via the AT1 receptor, induces an increase in intracellular calcium [Ca(2+)]i that then interacts with calmodulin (CaM). The Ca(2+)/CaM complex directly or indirectly activates sodium hydrogen ...
