ABSTRACT: Neural stem cells from different brain regions show differencies in gene expression patterns and physiological functions. We used microarrays to find differential gene expression between the neuralstem cells from the subventricular zone of lateral ventricle and the subventricular zone of third ventricle. Cultured neural stem cells from embryonic day 17.5 mouse embryos were selected for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain embryonic neural stem cell cultures from three indipendent females.

Project description:Astroglial cells in the adult brain constitute a heterogeneous population endowed with region-specific properties. Recently, they have acquired greater relevance as active components of the adult neural stem cell (aNSC) niches. Astrocytes located in the vicinity of aNSC reservoirs are thought to regulate aNSC behaviour. We have compared the function of glial cells isolated from the postnatal and adult subventricular zone and hippocampus (two stem cell niches, where aNSCs self-renew and give rise to immature neurons), from the olfactory bulb (a neurogenic region where the immature neurons cease to proliferate and terminally differentiate) and from a non-stem and non-neurogenic area such as the ventral mesencephalon. Co-culture experiments demonstrate that subventricular zone glial cells secrete soluble signals that promote NSC self-renewing divisions. We used microarrays to detail the global gene expression of astroglial cells isolated from four different brain regions (olfactory bulb, ventral mesencephalon, hippocampus and subventricular zone) and identified up-regulated genes coding for secreted proteins in astrocytes from the subventricular zone. Primary astrocytes were cultured from four CD-1 mouse brain regions and cells were employed for RNA extraction and hybridization on Affymetrix microarrays. Primary tissue for the astrocyte cultures was dissected from four postnatal day 3 littermate pups. The tissue from the three pups was pooled in order to reduce individual differences of expression profiles.

Project description:Long noncoding RNAs (lncRNAs) have been described in cell lines and various whole tissues, but lncRNA analysis of development in vivo is limited. Here, we comprehensively analyze lncRNA expression for the adult mouse subventricular zone neural stem cell lineage. We utilize complementary genome-wide techniques including RNA-seq, RNA CaptureSeq, and ChIP-seq to associate specific lncRNAs with neural cell types, developmental processes, and human disease states. By integrating data from chromatin state maps, custom microarrays, and FACS purification of the subventricular zone lineage, we stringently identify lncRNAs with potential roles in adult neurogenesis. shRNA-mediated knockdown of two such lncRNAs, Six3os and Dlx1as, indicate roles for lncRNAs in the glial-neuronal lineage specification of multipotent adult stem cells. Our data and workflow thus provide a uniquely coherent in vivo lncRNA analysis and form the foundation of a user-friendly online resource for the study of lncRNAs in development and disease. RNA CaptureSeq was perfomed on RNA extracted from adult mouse subventricular zone to better characterize rare lncRNA isoforms. Genomic regions used to design capture array are included in the raw file target_regions.bed.

RNA-seq (both paired end and single) from the adult neurogenic niches- subventricular zone (SVZ), olfactory bulb (OB), dentate gyrus (DG) and control non-neurogenic tissue, striatum (STR). Reads were used to assemble a lncRNA catalogue and determine expression values for both protein-coding and noncoding genes
