Structural and molecular basis of the peroxynitrite-mediated nitration and inactivation of Trypanosoma Cruzi iron-superoxide dismutases (fe-sods) A and B. Disparate susceptibilities due to the repair of tyr35 radical by cys83 in fe-sodb through intramolecular electron transfer
(American Society for Biochemistry and Molecular Biology, 2014-05)
Trypanosoma cruzi, the causative agent of Chagas disease, contains exclusively iron-dependent superoxide dismutases (Fe-SODs) located in different subcellular compartments. Peroxynitrite, a key cytotoxic and oxidizing ...
Direct action of aldosterone on bicarbonate reabsorption in in vivo cortical proximal tubule
(AMER PHYSIOLOGICAL SOC, 2009)
Pergher PS, Leite-Dellova D, de Mello-Aires M. Direct action of aldosterone on bicarbonate reabsorption in in vivo cortical proximal tubule. Am J Physiol Renal Physiol 296: F1185-F1193, 2009. First published February 18, ...
TRPC6 is the endothelial calcium channel that regulates leukocyte transendothelial migration during the inflammatory response
(Rockefeller University Press, 2015-09)
Leukocyte transendothelial migration (TEM) is a tightly regulated, multistep process that is critical to the inflammatory response. A transient increase in endothelial cytosolic free calcium ion concentration (↑[Ca2+]i) ...
Cyclic Guanosine Monophosphate Signaling Cascade Mediates Pigment Aggregation in Freshwater Shrimp Chromatophores
(MARINE BIOLOGICAL LABORATORY, 2009)
The cell signaling cascades that mediate pigment movements in crustacean chromatophores are not yet well established, although Ca(2+) and cyclic nucleotide second messengers are involved. Here, we examine the participation ...
Extracellular gentamicin reduces the activity of con nexin hemichannels and interferes with purinergic Ca2+ signaling in HeLa cells
(Frontiers Research Foundation, 2014)
Gap junction channels (GJCs) and hemichannels (HCs) are composed of protein subunits termed connexins (Cxs) and are permeable to ions and small molecules. In most organs, GJCs communicate the cytoplasm of adjacent cells, ...

Characterization of calcium transporters during the pollen tube growth in Arabidopsis thaliana
(Tech Science Press, 2019)
In plants, calcium signals are involved in multiple physiologicalprocesses such as stomatal opening, stress responses, and polarized growth ofroot hairs and pollen tubes. These signals are given as repetitive oscillationsof ...
