Project description:We performed a broad-spectrum microarray analysis using mRNA from 3 NL and 5 DS astrocyte cultures. The microarray output was validated for several genes To explore the relation between gene expression and potential oxidative stress in DS samples, we also evaluated the transcription profile in NL astrocytes subjected to mild oxidative stress (50µM H2O2 for 24 hr). Samples of total mRNA from NL cultures non treated (NT), normal cultures treated with H2O2 (T), DS cultures NT and DS cultures T were included in the arrays.

Project description:Astrocytes negatively impact neuronal development in a range of neurodevelopmental disorders (NDs), however how they do this, and if mechanisms are shared across multiple disorders, is not known. We developed an in vitro system to ask how astrocyte protein secretion and gene expression change in 3 genetic NDs (Fragile X syndrome (FXS), Rett's syndrome (RTT), Down's syndrome (DS)). This identified disorder specific changes, as well as core proteins that are increased in release in all 3 NDs. We provide a resource of astrocyte secreted proteins and gene expression in health and NDs, as well as novel targets for intervention in diverse NDs.
Project description:DS-ALL is a highly heterogeneous disease with predominance of an aberrant exp. of CRLF2 cooperating with mutated JAK2 Acute lymphoblastic pediatric leukemia specimens of Down's syndrome are examined for gene expression profiles and specific genetic aberrations. Gene expression profiling and specific genetic variation analysis identify novel pathways involved in DS-ALL pathogenesis.

Project description:The molecular mechanism involved in Down's syndrome (DS) is more complex than previously thought. This study provides a comprehensive overview of DS through the whole transcriptomic profile obteined by NGS of MSCs isolated from CV derived from women carrying foetuses with diagnosed DS in comparison to their euploid counterparts (CV), revealing the existence of a wide range of molecular signatures involved in the regulation of cell cycle, proliferation and phenotype.
