Ryanodine receptor-mediated Ca2+ release underlies iron-induced mitocondrial fission and stimulates mitocondrial Ca2+ uptake inprimary hippocampal neurons
(2014)
Mounting evidence indicates that iron accumulation impairs brain function. We have reported previously that addition of sub-lethal concentrations of iron to primary hippocampal neurons produces Ca2+ signals and promotes ...
Redox regulation of calcium release in skeletal and cardiac muscle
(Society of Biology of Chile, 2002)
In skeletal and cardiac muscle cells, specific isoforms of the Ryanodine receptor channels mediate Ca2+ release from the sarcoplasmic reticulum. These channels are highly susceptible to redox modifications, which regulate ...
Propolis green biofilm for the immobilization of carbon nanotubes and metallic ions: Development of redox catalysts
(2021-11-01)
Greener materials have been used in the construction of electrochemical devices, becoming one of the main strands of this scientific development area. Thin films based on natural and renewable sources, such as propolis, ...
Redox regulation of inflammatory processes
(Pergamon-Elsevier Science Ltd, 2016-12)
Oxidative stress mediators such as Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS) can be considered double edge molecules, whenever their role in inflammatory pathways is considered. Indeed, if on one ...
Redox metabolism in Trypanosoma cruzi. Biochemical characterization of dithiol glutaredoxin dependent cellular pathways
(Elsevier Science, 2014-08)
In Trypanosoma cruzi, the modification of thiols by glutathionylationedeglutathionylation and its potential relation to protective, regulatory or signaling functions have been scarcely explored. Herein we characterize a ...
Enzyme immobilisation on electroactive nanostructured membranes (ENM): Optimised architectures for biosensing
(ELSEVIER SCIENCE BV, 2008)
Electroactive nanostructured membranes have been produced by the layer-by-layer (LbL) technique, and used to make electrochemical enzyme biosensors for glucose by modification with cobalt hexacyanoferrate redox mediator ...
Metabolismo redox en Trypanosoma cruzi. Estudio de vías metabólicas dependientes de glutatión
(2014-10-14)
Muchas formas de vida han desarrollado mecanismos para resistir al desafío impuesto por las especies reactivas del oxígeno, o para utilizar estas especies con fines regulatorios o de señalización. En los parásitos ...
