A Hopping Mechanism for Cargo Transport by Molecular Motors on Crowded Microtubules
(SPRINGER, 2010)
Most models designed to study the bidirectional movement of cargos as they are driven by molecular motors rely on the idea that motors of different polarities can be coordinated by external agents if arranged into a ...
Regulation of Fe absorption by cultured intestinal epithelia (Caco-2) cell monolayers with varied Fe status
(1996)
Body Fe homeostasis is maintained through the regulation of Fe absorption by the intestinal epithelia. Working under the hypothesis that the intracellular concentration of Fe is instrumental in the control of its transepithelial ...
Ketamine effect on intracellular and mitochondrial calcium mobilization
(Instituto de Histología y Embriología, 2016-04)
The suppressive effects of ketamine on intracellular calcium has been reported in a variety of cells although the mechanisms involved are not well understood. The aim of this work was to evaluate the ketamine effect on the ...
Peroxynitrite affects Ca2+ transport in Trypanosoma cruzi
(Elsevier Science BvAmsterdamHolanda, 1999)
Water flux through human aquaporin 1: inhibition by intracellular furosemide and maximal response with high osmotic gradients
(Springer, 2011-06)
This work studies water permeability properties of human aquaporin 1 (hAQP1) expressed in Xenopus laevis oocyte membranes, applying a technique where cellular content is replaced with a known medium, with the possibility ...
Intracellular acidification reduces l-arginine transport via system y(+)l but not via system y(+)/cats and nitric oxide synthase activity in human umbilical vein endothelial cells
(2018)
L-Arginine is taken up via the cationic amino acid transporters (system y(+)/CATs) and system y(+)L in human umbilical vein endothelial cells (HUVECs). L-Arginine is the substrate for endothelial NO synthase (eNOS) which ...
From cartoons to quantitative models in Golgi transport
(Journal of the Serbian Chemical Society, 2020-12)
Background: Cell biology is evolving to become a more formal and quantitative science. In particular, several mathematical models have been proposed to address Golgi self-organisation and protein and lipid transport. ...
Decreased activity of the Na+/H+ exchanger by phosphodiesterase 5A inhibition is attributed to an increase in protein phosphatase activity
(Lippincott Williams, 2010-10)
The beneficial effect of phosphodiesterase 5A inhibition in ischemia/reperfusion injury and cardiac hypertrophy is well established. Inhibition of the cardiac Na(+)/H(+) exchanger (NHE-1) exerts beneficial effects on ...
