Role of carbon dioxide and ion transport in the formation of sub-embryonic fluid by the blastoderm of the Japanese quail [PDF]

open access: yes, 2002
1. The explanted blastoderm of the Japanese quail was used to explore the role of ions and carbon dioxide in determining the rate of sub-embryonic fluid (SEF) production between 54 and 72 h of incubation. 2.

Endogenous Ouabain [PDF]

open access: yesHypertension, 2016
In this brief article, we summarize recent reports about endogenous ouabain (EO), a cardiotonic steroid hormone. This includes analysis of mammalian EO, the discovery of EO isomers, regulation of intracellular signaling by EO, and the roles of EO in hypertension, pregnancy, and heart and kidney diseases.

Ouabain enhances ADPKD cell apoptosis via the intrinsic pathway

open access: yesFrontiers in Physiology, 2016
Progression of autosomal dominant polycystic kidney disease (ADPKD) is highly influenced by factors circulating in blood. We have shown that the hormone ouabain enhances several characteristics of the ADPKD cystic phenotype, including the rate of cell ...

Markedly divergent effects of Ouabain on a Temozolomide-resistant (T98G) vs. a Temozolomide-sensitive (LN229) Glioblastoma cell line

open access: yesDiscover Oncology, 2023
Background Glioblastoma multiforme (GBM) is the most aggressive primary brain tumor with poor prognosis. GMB are highly recurrent mainly because of radio- and chemoresistance.

Intracellular free sodium and potassium, post-carbachol hyperpolarization, and extracellular potassium-undershoot in rat sympathetic neurones [PDF]

open access: yes, 1983
Double-barrelled ion-sensitive microelectrodes were used to record the free intracellular Na+- and K+-concentrations ([Na+]i, [K+]i) and to determine their relation to changes in membrane potential and extracellular K+ ([K+]e) in rat sympathetic ganglia.

Sodium chloride transport of normal and dietary enlarged rat cecum in vitro [PDF]

open access: yes, 1998
Sodium chloride transport across isolated cecum mucosa was investigated in normal rats and rats with adaptive cecum growth induced by dietary polyethylene glycol (PEG). The normal cecum absorbed CI in excess of Na with a small short-circuit current (Isc).

THE EFFECT OF LITHIUM ON THE INOTROPIC EFFECT OF OUABAIN AND MANIFESTATION OF ARRHYTHMIA IN GUINEA-PIG ATRIA [PDF]

open access: yesActa Medica Iranica, 1995
rli....xposure ofthe guinea-pig whole a/ria to lithium (1 and 5 mM) produced a reduction ofinotropic response to ouubain. The inhibitory effect oflithium (1 m"f) was slight, whereas lithium (5 mM) significantly reduced tlze response oj the preparations ...

Radioiodinated Tyrosyl-Ouabain and Measurement of a Circulating Ouabain-like Compound [PDF]

open access: yesClinical Chemistry, 2001
Abstract Background: Assays for endogenous ouabain, a cardiac glycoside believed to be involved in blood pressure and volume regulation, are characterized by laboratory-specific plasma values that are measured by different assays. Because of this variability, our study focused on the development of a new 125I-labeled ouabain derivative ...

Ouabain Suppresses IL-6/STAT3 Signaling and Promotes Cytokine Secretion in Cultured Skeletal Muscle Cells

open access: yesFrontiers in Physiology, 2020
The cardiotonic steroids (CTS), such as ouabain and marinobufagenin, are thought to be adrenocortical hormones secreted during exercise and the stress response. The catalytic α-subunit of Na,K-ATPase (NKA) is a CTS receptor, whose largest pool is located

Ouabain affects cell migration via Na,K-ATPase-p130cas and via nucleus-centrosome association. [PDF]

open access: yesPLoS ONE, 2017
Na,K-ATPase is a membrane protein that catalyzes ATP to maintain transmembrane sodium and potassium gradients. In addition, Na,K-ATPase also acts as a signal-transducing receptor for cardiotonic steroids such as ouabain and activates a number of ...
