Ouabain alleviates Mycobacterium abscessus-triggered inflammatory responses through dual regulation of NLRP3 inflammasome activity and M1 macrophage polarization [PDF]
Frontiers in ImmunologyIntroductionMycobacterium abscessus (M. abscessus) is a highly drug-resistant pathogen responsible for chronic pulmonary inflammation in humans. The cardiac glycoside ouabain exhibits broad anti-inflammatory effects in various disease models, but its ...

The Influence of Ouabain on Human Dendritic Cells Maturation [PDF]
Mediators 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 ...

Radioimmunoassays, Ouabain-Like Material, and Ouabain [PDF]
Hypertension, 2005 To the Editor: We read with interest the article by Bauer et al1 on the changes in the plasma concentration of a ouabain-like compound associated with vigorous exercise in both humans and dogs. The authors comment on the result that is most striking to us, namely the remarkably high concentrations of the immunoassayable substance achieved without ...

Ouabain – a double-edged sword in tumor development and progression? a review of half a century [PDF]
Frontiers in PhysiologySince their first discovery as potential anti-cancer drugs there is increasing evidence that cardiotonic steroids e.g., Ouabain have anti-tumor properties by interacting with their natural receptor the Na+-K+-ATPase (NKA) and by inducing diverse ...

A low concentration of ouabain (0.18 µg/kg) enhances hypertension in spontaneously hypertensive rats by inhibiting the Na+ pump and activating the renin-angiotensin system [PDF]
Brazilian Journal of Medical and Biological Research, 2010 We investigated the effects of low ouabain concentrations on systolic (SAP) and diastolic (DAP) arterial pressures and on pressor reactivity in 3-month-old male spontaneously hypertensive rats (SHR). Arterial blood pressure (BP) and pressor reactivity to

Regulatory Ouabain Action on Excitatory Transmission in Rat Hippocampus: Facilitation of Synaptic Responses and Weakening of LTP [PDF]
BiomoleculesCardiotonic steroids (CTS), including the endogenous compound ouabain, modulate neuronal Na/K-ATPase (NKA) activity in a concentration-dependent manner, affecting neuronal survival and function.

A ouabain‐sensitive membrane conductance [PDF]
The Journal of Physiology, 1968 1. Changes in membrane conductance and potential of sodium‐loaded frog muscle fibres were found when the external recovery solution was changed: from cold to warm, to warm plus ouabain, to cold plus ouabain. Comparisons of these measurements for different external solutions were made by leaving the electrodes implanted in the same fibre during all ...

Ouabain Counteracts Retinal Ganglion Cell Death Through Modulation of BDNF and IL-1 Signaling Pathways [PDF]
Brain SciencesBackground: Ouabain is a steroid hormone that binds to the sodium pump (Na+, K+-ATPase) at physiological (nanomolar) concentrations, activating different signaling pathways.

Ouabain at nanomolar concentrations is cytotoxic for biliary tract cancer cells.
PLoS ONE, 2023 Biliary tract cancer is a deadly disease with limited therapeutic options. Ouabain is a well-known inhibitor of the pumping function of Na+/K+-ATPase, though there is evidence that low concentrations of ouabain lead to a reduction of cell viability of ...
