Anatomical landmarks localization for capsule endoscopy studies
Wireless Capsule Endoscopy is a medical procedure that uses a small, wireless camera to capture images of the inside of the digestive tract. The identification of the entrance and exit of the small bowel and of the large ...
Disruption of striatal glutamatergic transmission induced by mutant huntingtin involves remodelling of both postsynaptic density and NMDA receptor signalling
We study the striatal susceptibility to NMDA receptor (NMDAR)-</p><p>mediated injury of two Huntington’s disease (HD) transgenic mice:</p><p>R6/1 and R6/1:BDNF+/−. We found that R6/1:BDNF+/− mice – which</p><p>express ...
Cortical thickness modeling and variability in Alzheimer's disease and frontotemporal dementia.
Background and objective: Alzheimer's disease (AD) and frontotemporal dementia (FTD) show different patterns of cortical thickness (CTh) loss compared with healthy controls (HC), even though there is relevant heterogeneity ...
α4-α5 helices on surface of KRAS can accommodate small compounds that increase KRAS signaling while inducing CRC cell death
Abstract: KRAS is the most frequently mutated oncogene associated with the genesis and progress of pancreatic, lung and colorectal (CRC) tumors. KRAS has always been considered as a therapeutic target in cancer but until ...
Resolvin E1 derived from eicosapentaenoic acid prevents hyperinsulinemia and hyperglycemia in a host genetic manner
Eicosapentaenoic acid (EPA) has garnered attention after the success of the REDUCE-IT trial, which contradicted previous conclusions on EPA for cardiovascular disease risk. Here we first investigated EPA's preventative ...
El 'Real Decreto de Troncalidad' de la formación especializada
Una vez la troncalidad ha dejado de ser un proyecto para convertirse en un RD tangible en el papel del BOE, la Fundación Educación Médica (FEM)considera oportuno y pertinente reflexionar sobre qué es la troncalidad, para ...
Guía para la definición de los perfiles competenciales profesionales
La declaración de Bolonia de 1999 ha comportado diferentes cambios y retos en el mundo de la educación médica. Entre ellos, uno de los más relevantes es la elaboración de programas formativos basados en competencias ...
Intermediate filaments control collective migration by restricting traction forces and sustaining cell-cell contacts
Mesenchymal cell migration relies on the coordinated regulation of the actin and microtubule networks that participate in polarized cell protrusion, adhesion, and contraction. During collective migration, most of the ...
Neuroprotection: A New Therapeutic Approach of Relapsing Remitting Multiple Sclerosis
Neurodegenerative changes occurring early from primary acute immune-mediated inflammation support the hypothesis that multiple sclerosis (MS) is a complex disease. Axonal loss progresses with the disease course and ...
Aorta macrophage inflammatory and epigenetic changes in a murine model of obstructive sleep apnea: Potential role of CD36
Obstructive sleep apnea (OSA) affects 8-10% of the population, is characterized by chronic intermittent hypoxia (CIH), and causally associates with cardiovascular morbidities. In CIH-exposed mice, closely mimicking the ...
Protein Kinase Cδ and Calmodulin Regulate Epidermal Growth Factor Receptor Recycling from Early Endosomes through Arp2/3 Complex and Cortactin
The intracellular trafficking of the epidermal growth factor receptor (EGFR) is regulated by a cross-talk between calmodulin (CaM) and protein kinase Cδ (PKCδ). On inhibition of CaM, PKCδ promotes the formation of enlarged ...
Cytomegalovirus protein m154 perturbs the adaptor protein-1 compartment mediating broad-spectrum immune evasion
Cytomegaloviruses (CMVs) are ubiquitous pathogens known to employ numerous immunoevasive strategies that significantly impair the ability of the immune system to eliminate the infected cells. Here, we report that the single ...
Vacuole membrane protein 1 is an endoplasmic reticulum protein required for organelle biogenesis, protein secretion, and development
Vacuole membrane protein 1 (Vmp1) is membrane protein of unknown molecular function that has been associated with pancreatitis and cancer. The social amoeba Dictyostelium discoideum has a vmp1-related gene that we identified ...
The New Antitumor Drug ABTL0812 Inhibits the Akt/mTORC1 Axis by Upregulating Tribbles-3 Pseudokinase
Purpose: ABTL0812 is a novel first-in-class, small molecule which showed antiproliferative effect on tumor cells in phenotypic assays. Here we describe the mechanism of action of this antitumor drug, which is currently in ...
Dynamic and Regulated Association of Caveolin with Lipid Bodies: Modulation of Lipid Body Motility and Function by a Dominant Negative Mutant
Caveolins are a crucial component of caveolae but have also been localized to the Golgi complex, and, under some experimental conditions, to lipid bodies (LBs). The physiological relevance and dynamics of LB association ...
AMPAR/TARP stoichiometry differentially modulates channel properties
AMPARs control fast synaptic communication between neurons and their function relies on auxiliary subunits, which importantly modulate channel properties. Although it has been suggested that AMPARs can bind to TARPs with ...
The membrane-permeable calmodulin inhibitors (W-7/W-13) bind to membranes changing the electrostatic surface potential. Dual effect of W-13 on EGFR activation
Membrane-permeable calmodulin inhibitors, such as the napthalenesulfonamide derivatives W-7/W-13, trifluoperazine, and calmidazolium, are used widely to investigate the role of calcium/calmodulin (Ca2+/CaM) in living cells. ...
MYADM regulates Rac1 targeting to ordered membranes required for cell spreading and migration
Membrane organization into condensed domains or rafts provides molecular platforms for selective recruitment of proteins. Cell migration is a general process that requires spatiotemporal targeting of Rac1 to membrane rafts. ...
<em>Microglial CD300f immune receptor contributes to the maintenance of neuron viability in vitro and after a penetrating brain injury</em>
Emerging evidences suggest that immune receptors participate in diverse microglial and macrophage functions by regulating their immunometabolism, inflammatory phenotype and phagocytosis. CD300f, a TREM2-like lipid sensing ...
Mechanical control of the mammalian circadian clock via YAP/TAZ and TEAD
Autonomous circadian clocks exist in nearly every mammalian cell type. These cellular clocks are subjected to a multilayered regulation sensitive to the mechanochemical cell microenvironment. Whereas the biochemical signaling ...
