Association of microtubules and axonal RNA transferred from myelinating Schwann cells in rat sciatic nerve
(Public Library of Science, 2020)
Transference of RNAs and ribosomes from Schwann cell-to-axon was demonstrated in normal and regenerating peripheral nerves. Previously, we have shown that RNAs transfer is dependent on F-actin cytoskeleton and Myosin Va. ...
More than tracks: how the cytoskeleton builds epithelia asymmetry
(Universidad Nacional de La Plata. Facultad de Medicina. Centro de Investigaciones Cardiovasculares. Sociedad Argentina de Fisiología, 2018-04)
Epithelia are three-dimensional arrangements of cells organized into structures which delimit morphologically and physiologically different compartments. At the cellular level, epithelial cells are characterized by the ...
Exposure of Physalaemus cuvieri (Anura) to benzo[a]pyrene and α-naphthoflavone: Morphofunctional effects on hepatic melanomacrophages and erythrocytes abnormalities
(2021-09-15)
Benzo[a]pyrene (BaP) is a high-risk contaminant of elevated toxicity. Its biotransformation process occurs as the expression of CYP1A1 increases and produces toxic metabolites. In turn, α-naphthoflavone (aNF) represents ...
Morphological fluctuations of individual mitochondria in living cells
(IOP Publishing, 2022-03)
Uncovering the link between mitochondrial morphology, dynamics, positioning and function is challenging. Mitochondria are very flexible organelles that are subject to tension and compression within cells. Recent findings ...
Large-scale quantum effects in biological systems
(John Wiley & Sons IncHobokenEUA, 2005)
Formation of the female pronucleus and reorganization and disassembly of the first interphase cytoskeleton in the egg of the glossiphoniid leech Theromyzon rude
(Academic Press Inc., 1995)
Eggs of the leech Theromyzon rude were studied under dissecting, fluorescence, light, and electron microscopes. The sperm-derived centrosome divides and separates at early first interphase. The female pronucleus forms ...
Reduction of Tubulin Expression in Angomonas deanei by RNAi Modifies the Ultrastructure of the Trypanosomatid Protozoan and Impairs Division of Its Endosymbiotic Bacterium
(Wiley, 2016)
In the last two decades, RNA interference pathways have been employed as a useful tool for reverse genetics in trypanosomatids. Angomonas deanei is a nonpathogenic trypanosomatid that maintains an obligatory endosymbiosis ...
