Discovering new proteins in plant mitochondria by RNA editing simulation

2016

In plant mitochondria an essential mechanism for gene expression is RNA editing, often influencing the synthesis of functional proteins. RNA editing alters the linearity of genetic information transfer. Indeed it causes differences between RNAs and their coding DNA sequences that hinder both experimental and computational research of genes. Therefore common software tools for gene search, successfully applied to find canonical genes, often fail in discovering genes encrypted in the genome of plants. Here we propose a novel strategy useful to identify candidate coding sequences resulting from possible editing substitutions. In particular, we consider c!u substitutions leading to the creation…

Funciones protectoras de los astrocitos en la inflamación y el estrés oxidativo cerebral

2018

La enfermedad de Alzheimer (EA) es una enfermedad neurodegenerativa que se presenta con mayor prevalencia en la población anciana. Afecta a alrededor de 37 millones de personas en todo el mundo. Desde el punto de vista inmunohistoquímico, la EA se caracteriza por la presencia de placas neuríticas (con el péptido tóxico Aβ1-42, entre otros) y ovillos neurofibrilares en diversas áreas del cerebro, responsables de la pérdida neuronal, el deterioro de las conexiones sinápticas y la gliosis reactiva causando la inflamación característica de esta enfermedad. Resultados previos indican que los astrocitos son células de protección para las neuronas y que podrían proteger de la inflamación y del est…

Mouse model for Charcot Marie-Tooth as a tool to better understand the disease

2016

Introducción La enfermedad de Charcot-Marie-Tooth (CMT) es uno de los trastornos neurológicos hereditarios más comunes que afecta a 17-40 de cada 100.000 personas según poblaciones; concretamente esta cifra se sitúa en 28 personas de cada 100.000 en España. La enfermedad recibe el nombre de los tres médicos que la identificaron por primera vez en 1886; Jean-Marie Charcot y Pierre Marie en París, Francia y Howard Henry Tooth en Cambridge, Inglaterra. La enfermedad de CMT, también conocida como neuropatía hereditaria motora y sensitiva o atrofia muscular del peroneo, abarca un grupo de trastornos que afectan los nervios periféricos. El fenotipo clásico incluye problemas en la marcha, déficit …

Estudio del estrés oxidativo en un modelo animal de ejercicio físico: análisis citométrico en mitocondrias aisladas y en leucocitos

2015

Un incremento en el metabolismo aeróbico durante el ejercicio es una fuente potencial de estrés oxidativo. En el músculo, la mitocondria es una fuente importante de intermediarios reactivos. Para su estudio, se han utilizado el hígado, el músculo de diafragma y el corazón de conejos tipo control sin entrenamiento físico específico, conejos entrenados sometidos a un entrenamiento físico específico y conejos sometidos a una operación simulada. Se han obtenido mitocondrias aisladas para su estudio mediante ensayos polarigráficos de consumo de oxígeno o respiración mitocondrial mediante la adición de sustratos oxidativos y ADP y ensayos del potencial de membrana mitocondrial mediante la captaci…

Manipulating mtDNA in vivo reprograms metabolism via novel response mechanisms.

2019

Mitochondria have been increasingly recognized as a central regulatory nexus for multiple metabolic pathways, in addition to ATP production via oxidative phosphorylation (OXPHOS). Here we show that inducing mitochondrial DNA (mtDNA) stress in Drosophila using a mitochondrially-targeted Type I restriction endonuclease (mtEcoBI) results in unexpected metabolic reprogramming in adult flies, distinct from effects on OXPHOS. Carbohydrate utilization was repressed, with catabolism shifted towards lipid oxidation, accompanied by elevated serine synthesis. Cleavage and translocation, the two modes of mtEcoBI action, repressed carbohydrate rmetabolism via two different mechanisms. DNA cleavage activ…

Efavirenz induce una respuesta diferencial en la bioenergética y función mitocondrial de neuronas y células gliales

2014

Efavirenz (EFV) es el inhibidor de la transcriptasa inversa no análogos de nucleósidos (ITINAN) más ampliamente utilizado en el tratamiento de la infección por el VIH. Durante muchos años ha contribuido significativamente a la evolución de la terapia antirretroviral de gran actividad (TARGA) y a pesar de ser considerado un fármaco seguro y bien tolerado, existe una creciente preocupación debido a que los regímenes que lo contienen han sido asociados con efectos adversos, siendo los trastornos neuropsiquiátricos la reacción adversa más notable y un factor de riesgo para el fracaso de la terapia. Los mecanismos responsables no han sido caracterizados, aunque algunos trabajos recientes vincula…

Clinical manifestations and management of four children with Pearson syndrome.

2011

Pearson marrow-pancreas syndrome is a fatal disorder mostly diagnosed during infancy and caused by mutations of mitochondrial DNA. We hereby report on four children affected by Pearson syndrome with hematological disorders at onset. The disease was fatal to three of them and the fourth one, who received hematopoietic stem cell transplantation, died of secondary malignancy. In this latter patient transplantation corrected hematological and non-hematological issues like metabolic acidosis, and we therefore argue that it could be considered as a useful option in an early stage of the disease.
