Integration of genome-wide approaches identifies lncRNAs of adult neural stem cells and their progeny in vivo [RNA CaptureSeq]

ABSTRACT: 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

SVZ monolayer cultures were differentiated in vitro for 1,2,4 days, and gene expression changes were measured. SVZ lineage was isolated by FACS using established protocols to separate transit amplifying (TA), neuroblast (NB), activated stem cells (NSCs), and niche astrocytes (astros), and gene expression of each cell type was measured. All arrays are custom lncRNA arrays.

Single-Cell Transcriptomics Reveals a Population of Dormant Neural Stem Cells that Become Activated upon Brain Injury

Project description:Heterogeneous pools of adult neural stem cells (NSCs) contribute to brain maintenance and regeneration after injury. The balance of NSC activation and quiescence, as well as the induction of lineage-specific transcription factors, may contribute to diversity of neuronal and glial fates. To identify molecular hallmarks governing these characteristics, we performed single-cell sequencing of an unbiased pool of adult subventricular zone NSCs. This analysis identified a discrete, dormant NSC subpopulation that already expresses distinct combinations of lineage-specific transcription factors during homeostasis. Dormant NSCs enter a primed-quiescent state before activation, which is accompanied by downregulation of glycolytic metabolism, Notch, and BMP signaling and a concomitant upregulation of lineage-specific transcription factors and protein synthesis. In response to brain ischemia, interferon gamma signaling induces dormant NSC subpopulations to enter the primed-quiescent state. This study unveils general principles underlying NSC activation and lineage priming and opens potential avenues for regenerative medicine in the brain. Single cell RNAseq of cells isolated from their in vivo niche in the subventricular zone, Striatum and Cortex during homeostasis as well as following ischemic injury. In total 272 single cells. (<WT>: homeostasis samples; <Ischemic_injured> and <Ischemic_injured_and_Interferon_gamma_knockout>: samples following ischemic injuried).
