Description
The role of post-transcriptional gene regulation in human brain development and cognitive diseases remains mostly uncharacterized. ELAV-like RNA binding proteins are a family of proteins that regulate several aspects of neuronal function including neuronal excitability and synaptic transmission. Here, we identify the downstream transcriptional networks of ELAVL2, an RNA-binding protein with unknown function in the brain. We knockdown expression of ELAVL2 in human neurons and conduct RNA-sequencing, identifying networks of differentially expressed and alternatively spliced genes with altered ELAVL2. These networks contain autism-relevant genes as well as previously identified targets of other RNA binding proteins implicated in autism spectrum disorders such as RBFOX1 and FMRP. ELAVL2-regulated coexpression networks are also enriched for synaptic genes as well as genes with human-specific patterns of gene expression in the frontal pole. Together, these data suggest that ELAVL2 regulation of transcript expression is critical for neuronal functions at risk in autism spectrum disorders and such mechanisms of post-transcriptional gene regulation may have contributed to human brain evolution. Overall design: We carried out RNA-sequencing (RNA-seq) of human neural progenitors cells. For the RNA-seq, 5 indipendent replicates were used for the neural progenitor cells. Primary human neural progenitor cultures were derived from mid-gestation fetal brain. Cells were transduced with a lentivirus containing a specific shRNA to ELAVL2 or a control shRNA. Cells were differentiated into neurons for 4 weeks and then harvested.

Description
It has been shown previously that endothelial cells and LepR+ stromal cells are the main sources of SCF in vivo in the mouse bone marrow. We tested whether SCF from endothelial cells and/or LepR+ stromal cells is important for the maintenance of hematopoietic progenitors and erythroid progenitors in mouse bone marrow by conditional deletion of Scf from these two cell types. We discovered that Scf deletion from LepR+ stromal cells, but not endothelial cells, reduced the numbers of hematopoietic progenitors and erythroid progenitors in mice. We performed RNA-Seq on PreCFU-E and CFU-E progenitors from control mice and from mice with Scf deletion from LepR+ stromal cells. We discovered that lack of SCF from LepR+ cells induces a premature differentiation of PreCFU-E and CFU-E progenitors. Overall design: Examination of gene expression profile in 2 cell tyeps from 3 different genetic backgrounds

Description
The transcriptional response to many widely used drugs and its modulation by genetic variability is poorly understood. Here we present an analysis of RNAseq profiles from heart tissue of 18 inbred mouse strains treated with the ß-blocker atenolol (ATE) and the ß-agonist isoproterenol (ISO). Differential expression analyses revealed a large set of genes responding to ISO (n=1770 at FDR=0.0001) and a comparatively small one responding to ATE (n=23 at FDR=0.0001). At a less stringent definition of differential expression, the transcriptional responses to these two antagonistic drugs are reciprocal for many genes, with an overall anti-correlation of r= -0.3. This trend is also observed at the level of most individual strains even though the power to detect differential expression is significantly reduced. The inversely expressed gene sets are enriched with genes annotated for heart-related functions. Modular analysis revealed gene sets that exhibited coherent transcription profiles across some strains and/or treatments. Correlations between such modules and a broad spectrum of cardiovascular traits are stronger than expected by chance. This provides evidence for the overall importance of transcriptional regulation for these organismal responses and explicits links between co-expressed genes and the traits they are associated with. Gene set enrichment analysis of differentially expressed groups of genes pointed to pathways related to heart development and functionality. Our study provides new insights into the transcriptional response of the heart to perturbations of the ß-adrenergic system, implicating several new genes that had not been associated to this system previously. Overall design: Cardiac mRNA expression profiles of the various inbred mouse strains were examined either under baseline condition (control) or in response to chronic administration of isoproterenol or atenolol at 10 mg/kg per day for 2 weeks. Expression data were produced by RNA-sequencing, in triplicates, using the HiSeq 2000 Illumina platform. Only males, aged ten to twelve weeks on average, were included in the experimental protocol. Mouse ID numbers refer to those described in Berthonneche C. et al. PLoS One. 2009 Aug 12;4(8):e6610 (doi: 10.1371/journal.pone.0006610. PMID: 19672458). Corresponding individual phenotypic values, in particular heart rate, systolic blood pressure, electrocardiogaphic measurements and heart weight are available in dataset "maurer1" of the Mouse Phenome Database (http://phenome.jax.org/). Preparation of the sequencing libraries, RNA-sequencing and RNA expression quantitations were performed by the BGI.

Description
In the following experiment, three different hESC cell lines (HES2, MEL1 and H9) were grown in the presence of KOSR, KOSR or mTESR containing media respectively. KOSR (Knockout serum replacement medium) is a standard media allowing the growth of hESC without the need for manual passaging - Enzymatic passaging is used instread. mTESR (Ludwig et al., 2007) is a media allowing the growth of hESC on matrigel with enzymatic passaging. At day 7 after passaging, these cells were FACs sorted for the presence of GCTM-2 and CD9 into 4 distinct fractions (p4: GCTM-2-neg, CD9-neg; p5: GCTM-2-low, CD9-low; p6: GCTM-2-medium, CD9-medium and p7: GCTM-2-high, CD9-high). For each cell line-subfraction combination, RNA was harvested and subject to microarray.
