Effects of small doses of ouabain on the arterial blood pressure of anesthetized hypertensive and normotensive rats

open access: yesBrazilian 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 ...

Ouabain Increases Gap Junctional Communication in Epithelial Cells

open access: yesCellular Physiology and Biochemistry, 2014
Background/Aims: The finding that endogenous ouabain acts as a hormone prompted efforts to elucidate its physiological function. In previous studies, we have shown that 10 nM ouabain (i.e., a concentration within the physiological range) modulates cell ...

Ouabain, a cardiac glycoside, inhibits the Fanconi anemia/BRCA pathway activated by DNA interstrand cross-linking agents. [PDF]

open access: yesPLoS ONE, 2013
Modulation of the DNA repair pathway is an emerging target for the development of anticancer drugs. DNA interstrand cross-links (ICLs), one of the most severe forms of DNA damage caused by anticancer drugs such as cisplatin and mitomycin C (MMC ...

Effect of ouabain on calcium signaling in rodent brain: A systematic review of in vitro studies

open access: yesFrontiers 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

The Metabolism of Ouabain in the Rat

open access: yesJournal of Pharmacy and Pharmacology, 1959
Abstract The urinary and biliary excretion of ouabain by rats has been estimated by paper chromatographic, colorimetric and biological methods of assay. After a dose of 1 μg./g., ouabain was excreted to the extent of approximately 90 per cent in bile and 4 per cent in urine.

The Influence of Ouabain on Human Dendritic Cells Maturation

open access: yesMediators of Inflammation, 2014
Although known as a Na,K-ATPase inhibitor, several other cellular and systemic actions have been ascribed to the steroid Ouabain (Oua). Particularly in the immune system, our group showed that Ouabain acts on decreasing lymphocyte proliferation ...

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.

Anti-inflammatory and Antinociceptive Activity of Ouabain in Mice

open access: yesMediators of Inflammation, 2011
Ouabain, an inhibitor of the Na+/K+-ATPase pump, was identified as an endogenous substance of human plasma. Ouabain has been studied for its ability to interfere with various regulatory mechanisms. Despite the studies portraying the ability of ouabain to

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 ...

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 ...
