Rem2 GTPase maintains survival of human embryonic stem cells as well as enhancing reprogramming by regulating p53 and cyclin D1
Human pluripotent stem cells, such as embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs), have the unique abilities of differentiation into any cell type of the organism (pluripotency) and indefinite ...
Synapse elimination activates a coordinated homeostatic presynaptic response in an autaptic circuit
The number of synapses present in a neuronal circuit is not fixed. Neurons must compensate for changes in connectivity caused by synaptic pruning, learning processes or pathological conditions through the constant adjustment ...
Major Challenges in clinical management of TB/HIV coinfected patients in Eastern Europe compared with Western Europe and Latin America
Objectives: rates of TB/HIV coinfection and multi-drug resistant (MDR)-TB are increasing in Eastern Europe (EE). We aimed to study clinical characteristics, factors associated with MDR-TB and predicted activity of empiric ...
GNIP1 E3 ubiquitin ligase is a novel player in regulating glycogen metabolism in skeletal muscle.
Background: Glycogenin-interacting protein 1 (GNIP1) is a tripartite motif (TRIM) protein with E3 ubiquitin ligase activity that interacts with glycogenin. These data suggest that GNIP1 could play a major role in the control ...
¿Por qué las mujeres con cáncer de mama deben estar guapas y los hombres con cáncer de próstata pueden ir sin afeitar? Oncología, disidencia y cultura hegemónica
El universo oncológico, aparentemente, constituye un ámbito de profundos consensos; aliviar el sufrimiento de pacientes y familias, la búsqueda de una cura efectiva o erradicar el estigma asociado al diagnóstico son objetivos ...
Stable and Efficient Genetic Modification of Cells in the Adult Mouse V-SVZ for the Analysis of Neural Stem Cell Autonomous and Non-autonomous Effects
Relatively quiescent somatic stem cells support life-long cell renewal in most adult tissues. Neural stem cells in the adult mammalian brain are restricted to two specific neurogenic niches: the subgranular zone of the ...
Neurofibromatosis tipo 2: La historia de Lidia
La Neurofibromatosis tipo 2 (NF2) es una enfermedad minoritaria hereditaria caracterizada por la presentación progresiva de múltiples tumores, especialmente Schwanomas Vestibulares Bilaterales, a partir de la segunda década ...
Lymphangioleiomyomatosis biomarkers linked to lung metastatic potential and cell stemness
Lymphangioleiomyomatosis (LAM) is a rare lung-metastasizing neoplasm caused by the proliferation of smooth muscle-like cells that commonly carry loss-of-function mutations in either the tuberous sclerosis complex 1 or 2 ...
Impaired expression of ectonucleotidases in ectopic and eutopic endometrial tissue is in favor of ATP accumulation in the tissue microenvironment in endometriosis
Endometriosis is a prevalent disease defined by the presence of endometrial tissue outside the uterus. Adenosine triphosphate (ATP), as a proinflammatory molecule, promotes and helps maintain the inflammatory state of ...
Activity and high-order effective connectivity alterations in Sanfilippo C patient-specific neuronal networks
Induced pluripotent stem cell (iPSC) technology has been successfully used to recapitulate phenotypic traits of several human diseases in vitro. Patient-specific iPSC-based disease models are also expected to reveal early ...
Allele-Specific Expression of APC in Adenomatous Polyposis Families
BACKGROUND & AIMS: Germline mutations in the APC gene cause of most cases of familial adenomatous polyposis (FAP) and a lesser proportion of attenuated FAP (AFAP). Systematic analysis of APC at the RNA level could provide ...
The multidrug-resistant PMEN1 pneumococcus is a paradigm for genetic success
Background: Streptococcus pneumoniae, also called the pneumococcus, is a major bacterial pathogen. Since its introduction in the 1940s, penicillin has been the primary treatment for pneumococcal diseases. Penicillin ...
Theophylline is able to partially revert cachexia in tumour-bearing rats
Background and aims: the aim of the present investigation was to examine the anti-wasting effects of theophylline (a methylxantine present in tea leaves) on a rat model of cancer cachexia. Methods: the in vitro effects of ...
Iron overload causes endolysosomal deficits modulated by NAADP-regulated two pore channels and RAB7A
Various neurodegenerative disorders are associated with increased brain iron content. Iron is known to cause oxidative stress, which concomitantly promotes cell death. Whereas endolysosomes are known to serve as intracellular ...
From proteomic analysis to potential therapeutic targets: functional profile of two lung cancer cell lines, A549 and SW900, widely studied in pre-clinical research
Lung cancer is a serious health problem and the leading cause of cancer death worldwide. The standard use of cell lines as in vitro pre-clinical models to study the molecular mechanisms that drive tumorigenesis and access ...
Using iPS Cells toward the Understanding of Parkinson's Disease
Cellular reprogramming of somatic cells to human pluripotent stem cells (iPSC) represents an efficient tool for in vitro modeling of human brain diseases and provides an innovative opportunity in the identification of new ...
CB1 cannabinoid receptor enrichment in the ependymal region of the adult human spinal cord
Cannabinoids are involved in the regulation of neural stem cell biology and their receptors are expressed in the neurogenic niches of adult rodents. In the spinal cord of rats and mice, neural stem cells can be found in ...
Hippocampal radial glial subtypes and their neurogenic potential in human fetuses and healthy and Alzheimer's disease adults
Neuropathological conditions might affect adult granulogenesis in the adult human dentate gyrus. However, radial glial cells (RGCs) have not been well characterized during human development and aging. We have previously ...
The Parkinson's disease-associated GPR37 receptor interacts with striatal adenosine A2A receptor controlling its cell surface expression and function in vivo
G protein-coupled receptor 37 (GPR37) is an orphan receptor associated to Parkinson's disease (PD) neuropathology. Here, we identified GPR37 as an inhibitor of adenosine A2A receptor (A2AR) cell surface expression and ...
Untangling dopamine-adenosine receptor assembly in experimental parkinsonism in rats
Parkinson's disease (PD) is a dopaminergic-related pathology in which functioning of the basal ganglia is altered. It has been postulated that a direct receptor-receptor interaction - i.e. of dopamine D-2 receptor (D2R) ...
