Análisis poblacional y filogeográfico de vectores de la enfermedad de Chagas en Perú basado en análisis multigénicos del ADN ribosomal y mitocondrial

2017

La enfermedad de Chagas, cuyo agente causal es Trypanosoma cruzi, constituye un grave problema de salud pública en toda Latinoamérica. La principal forma de transmisión es la vectorial, de la que son responsables hemípteros redúvidos de la subfamilia Triatominae adaptados a los hábitats doméstico y peridoméstico. Puesto que el parásito se mantiene en un ciclo zoonótico silvestre y es imposible de eliminar, la principal forma de lucha contra la transmisión vectorial consiste en la eliminación de las poblaciones domiciliadas del vector. Los estudios moleculares constituyen una herramienta de gran utilidad a la hora de planificar las campañas de control vectorial, puesto que permiten conocer y…

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…

Estudio del contenido y del estado mitocondrial en el blastocisto humano

2022

El contenido de ácido desoxirribonucleico (ADN) mitocondrial (ADNmt) por célula como marcador de viabilidad embrionaria se propuso como una estrategia muy innovadora para la priorización en la selección de embriones humanos en los tratamientos reproducción asistida, siendo los embriones con menor contenido mitocondrial por célula los candidatos a ser transferidos. La hipótesis de partida se basaba en que dichos embriones presentarían un estado metabólico más apropiado y un menor estrés celular, los cuales se traducirían en una mayor probabilidad de implantación. La elevada expectación inicialmente generada alrededor de este marcador, vino acompañada de publicaciones con resultados contradic…
