Plant extracellular vesicles are incorporated by a fungal pathogen and inhibit its growth
(Oxford University Press, 2017-09-23)
Extracellular vesicles (EV) are membrane particles released by cells into their environment and are considered to be key players in intercellular communication. EV are produced by all domains of life but limited knowledge ...
Metabolic and functional analysis of an aquous extract of Ugni molinae Turcz on refrigerated boar sperm.
(2019)
The world pork market grows every year. This type of food is a good source of B vitamins and is considered a cheap alternative of animal protein. In the pig breeding industry, artificial insemination (AI) is the best system ...
Dexamethasone-induced muscular atrophy is mediated by functional expression of connexin-based hemichannels
(2016)
Long-term treatment with high glucocorticoid doses induces skeletal muscle atrophy. However, the molecular mechanism of such atrophy remains unclear. We evaluated the possible involvement of connexin-based hemichannels (Cx ...
Interleukin-1ß regulates nitric oxide production and gamma-glutamyltranspeptidase activity in Sertoli cells
(American Society of Andrology, 2000-12)
Several cytokines have been involved in the regulation of Sertoli cell function. Further investigations are required to elucidate the role of interleukin-1beta (IL1beta) in Sertoli cell physiology. Twenty-day-old rat ...
Microtubules regulate brush border formation
(Wiley-liss, Div John Wiley & Sons Inc, 2018-02)
Most epithelial cells contain apical membrane structures associated to bundles of actin filaments, which constitute the brush border. Whereas microtubule participation in the maintenance of the brush border identity has ...
Brain cortex mitochondrial bioenergetics in synaptosomes and non-synaptic mitochondria during aging
(Springer/Plenum Publishers, 2016-01)
Alterations in mitochondrial bioenergetics have been associated with brain aging. In order to evaluate the susceptibility of brain cortex synaptosomes and non-synaptic mitochondria to aging-dependent dysfunction, male Swiss ...
Mutational Replacements at the "glycine Hinge" of the Escherichia coli Chemoreceptor Tsr Support a Signaling Role for the C-Helix Residue
(American Chemical Society, 2017-07)
Bacterial chemoreceptors are dimeric membrane proteins that transmit signals from a periplasmic ligand-binding domain to the interior of the cells. The highly conserved cytoplasmic domain consists of a long hairpin that ...
Cardiac ischemic preconditioning prevents dystrophin proteolysis by MMP-2 inhibition
(Instituto de Histología y Embriología, 2016-09)
Dystrophin is a membrane-associated protein responsible for structural stability of the sarcolemma in cardiac myocytes and is very sensitive to ischemic damage. The goal of our study was to determine if ischemic preconditioning ...
Estrogen receptor-α promotes endothelial cell motility through focal adhesion kinase
(Oxford University Press, 2011-04)
Sex steroids play a key role in cell movement and tissue organization. Cell migration requires the integration of events that induce changes in cell structure such as protrusion, polarization and traction toward the direction ...
The actin cytoskeleton participates in the early events of autophagosome formation upon starvation induced autophagy
(Landes Bioscience, 2012-08-06)
Autophagy is a process by which cytoplasmic material is sequestered in a double-membrane vesicle destined for degradation. Nutrient deprivation stimulates the pathway and the number of autophagosomes in the cell increases ...
