Intracellular monovalent ions as second messengers

SN Orlov, P Hamet - The Journal of membrane biology, 2006 - Springer
It is generally accepted that electrochemical gradients of monovalent ions across the plasma
membrane, created by the coupled function of pumps, carriers and channels, are involved in …

Ouabain induces cell proliferation through calcium-dependent phosphorylation of Akt (protein kinase B) in opossum kidney proximal tubule cells

SJ Khundmiri, MA Metzler, M Ameen… - … of Physiology-Cell …, 2006 - journals.physiology.org
Cardiotonic glycosides, like ouabain, inhibit Na+-K+-ATPase. Recent evidence suggests
that low molar concentrations of ouabain alter cell growth. Studies were conducted to …

Contacts and cooperation between cells depend on the hormone ouabain

I Larre, A Ponce, R Fiorentino… - Proceedings of the …, 2006 - National Acad Sciences
Cell adhesion is a crucial step in proliferation, differentiation, migration, apoptosis, and
metastasis. In previous works we have shown that cell adhesion is modulated by ouabain, a …

The MgtC Virulence Factor of Salmonella enterica Serovar Typhimurium Activates Na+,K+-ATPase

D Günzel, LM Kucharski, DG Kehres… - Journal of …, 2006 - Am Soc Microbiol
The mgtC gene of Salmonella enterica serovar Typhimurium encodes a membrane protein
of unknown function that is important for full virulence in the mouse. Since mgtC is part of an …

The death of cardiotonic steroid‐treated cells: evidence of Na+i,K+i‐independent H+i‐sensitive signalling

SN Orlov, P Hamet - Acta Physiologica, 2006 - Wiley Online Library
Na/K‐ATPase is the only known target of cardiotonic steroids (CTS) identified in plants,
amphibians and later on in several mammalian species, including human. We focus our …

[PDF][PDF] The rapid decline of MTT reduction is not a marker of death signaling in ouabain-treated cells

OA Akimova, AA Mongin, P Hamet, SN Orlov - Cell Mol Biol, 2006 - academia.edu
Decreased staining with dimethylthiazol diphenyltetrazolium (MTT) is widely used for cell
death detection. This study examined MTT assay as a marker of the Na+ i, K+ i-independent …

Modest intracellular acidification suppresses death signaling in ouabain-treated cells

OA Akimova, D Pchejetski, P Hamet, SN Orlov - Pfluegers Archiv, 2006 - Springer
The signaling cascade resulting in the death of several types of cells treated with ouabain or
other cardiotonic steroids (CTS) remains poorly understood. Recently, we observed that …

The Na+/K+-ATPase as [K+] o sensor: Role in cardiovascular disease pathogenesis and augmented production of endogenous cardiotonic steroids

O Akimova, J Tremblay, P Hamet, SN Orlov - Pathophysiology, 2006 - Elsevier
Current evidence demonstrates that augmented production of endogenous cardiotonic
steroids (CTS) such as ouabain and marinobufagenin is involved in the pathogenesis of …
