Cardiac Glycoside Ouabain Exerts Anticancer Activity via Downregulation of STAT3
Frontiers in Oncology, 2021 Cardiac glycosides are plant-derived steroid-like compounds which have been used for the treatment of cardiovascular diseases. Ouabain, a cardiotonic steroid and specific Na+/K+-ATPase inhibitor, has been rediscovered for its potential use in the ...

Stabilisation of Na,K-ATPase structure by the cardiotonic steroid ouabain [PDF]
, 2013 Cardiotonic steroids such as ouabain bind with high affinity to the membrane-bound cation-transporting P-type Na,K-ATPase, leading to complete inhibition of the enzyme.

Activity-dependent adenosine release may be linked to activation of Na+-K+ ATPase : an in vitro rat study [PDF]
, 2014 In the brain, extracellular adenosine increases as a result of neuronal activity. The mechanisms by which this occurs are only incompletely understood. Here we investigate the hypothesis that the Na+ influxes associated with neuronal signalling activate ...

Much More than a Cardiotonic Steroid: Modulation of Inflammation by Ouabain
Frontiers in Physiology, 2017 Since the discovery of ouabain as a cardiotonic steroid hormone present in higher mammals, research about it has progressed rapidly and several of its physiological and pharmacological effects have been described.

Ouabain-induced cytoplasmic vesicles and their role in cell volume maintenance [PDF]
, 2015 Cellular swelling is controlled by an active mechanism of cell volume regulation driven by a Na+/K+-dependent ATPase and by aquaporins which translocate water along the osmotic gradient. Na+/K+-pump may be blocked by ouabain, a digitalic derivative, by

Effect of ouabain on calcium signaling in rodent brain: A systematic review of in vitro studies
Frontiers in Pharmacology, 2022 The Na+/K+-ATPase is an integral membrane ion pump, essential to maintaining osmotic balance in cells in the presence of cardiotonic steroids; more specifically, ouabain can be an endogenous modulator of the Na+/K+-ATPase. Here, we conducted a systematic

Characterisation of the Na, K pump current in atrial cells from patients with and without chronic atrial fibrillation [PDF]
, 2003 <b>Objective:</b> To assess the contribution of the Na, K pump current (<i>I</i><sub>p</sub>) to the action potential duration (APD) and effective refractory period (ERP) in human atrial cells, and to investigate ...

Brazilian Journal of Medical and Biological Research, 2001 Ouabain increases vascular resistance and may induce hypertension by inhibiting the Na+ pump. The effects of 0.18 and 18 µg/kg, and 1.8 mg/kg ouabain pretreatment on the phenylephrine (PHE; 0.1, 0.25 and 0.5 µg, in bolus)-evoked pressor responses were ...

Wistar rats resistant to the hypertensive effects of ouabain exhibit enhanced cardiac vagal activity and elevated plasma levels of calcitonin gene-related peptide. [PDF]
PLoS ONE, 2014 Ouabain is a cardiac glycoside produced in the adrenal glands and hypothalamus. It affects the function of all cells by binding to Na+/K+-ATPase. Several lines of evidence suggest that endogenous ouabain could be involved in the pathogenesis of essential

Consequences of the Lack of TNFR1 in Ouabain Response in the Hippocampus of C57BL/6J Mice
Biomedicines, 2022 Ouabain is a cardiac glycoside that has a protective effect against neuroinflammation at low doses through Na+/K+-ATPase signaling and that can activate tumor necrosis factor (TNF) in the brain.
