Ythdf is a N6‐methyladenosine reader that modulates Fmr1 target mRNA selection and restricts axonal growth in Drosophila
2021
Abstract N6‐methyladenosine (m6A) regulates a variety of physiological processes through modulation of RNA metabolism. This modification is particularly enriched in the nervous system of several species, and its dysregulation has been associated with neurodevelopmental defects and neural dysfunctions. In Drosophila, loss of m6A alters fly behavior, albeit the underlying molecular mechanism and the role of m6A during nervous system development have remained elusive. Here we find that impairment of the m6A pathway leads to axonal overgrowth and misguidance at larval neuromuscular junctions as well as in the adult mushroom bodies. We identify Ythdf as the main m6A reader in the nervous system,…
El síndrome del cromosoma X Frágil: fenotipo conductual y dificultades de aprendizaje
2015
In this article, we describe the behavioral phenotype of individuals with Fragile X Syndrome and its impact in the educational scope. This syndrome is characterized by difficulties in sensory integration, cognitive deficits (verbal reasoning, abstract/ visual and cuantitative skills, short term memory, sequential processing, attention and executive processes), language disorders (phonetic-phonologicals, semanticals, morphosyntacticals and pragmaticals) and communication disorders, social anxiety, general hyperarousal, autism, non autistic social difficulties, attention deficit and hyperactivity, and learning disabilities. The behavioral phenotype is highly variable and depends on sex, age, …
Impact of Fragile X Syndrome on Their Families
2020
espanolEl objetivo del presente estudio es describir las alteraciones conductuales y emocionales en el sindrome de X fragil (SXF) y analizar las reperecusiones de tener un miembro con SXF en diferentes aspectos del funcionamiento familiar. Participaron 79 padres con un miembro con SXF y 80 padres con un miembro con desarrollo tipico. Los resultados mostraron que entre el 17% y el 66% de los ninos y adolescentes con SXF mostraron trastornos conductuales y emocionales significativos y menos comportamientos prosociales. Ademas, despues de controlar las dificultades emocionales y de comportamiento, nuestros resultados mostraron que las familias afectadas por SXF experimentaron un impacto mas ne…
