Description
We report RNA-sequencing data from zebrafish embryos lacking both maternal and zygotic expression of udu (which encodes Gon4l) (MZudu) at tailbud (TB) stage. Transcripts were compared to stage-matched wild-type (WT) embryos to identify differentially expressed genes. Overall design: Sequencing of polyadenylated mRNAs from MZudu mutant and control WT embryos with 2 biological and 2 technical replicates per genotype - each with 3 lanes per sample.
Publication Title
Gon4l regulates notochord boundary formation and cell polarity underlying axis extension by repressing adhesion genes.

Description
Human embryonic stem cells (hESCs) were specified as ventral telencephalic neuroectoderm (day 4) and then into medial ganglionic emininence (MGE)-like progenitors (day 15) and were subsequently differentiated into cortical interneuron (cIN)-like cells (day 25-35), by modification of previously published protocols. RNA-seq analysis at days 0, 4, 15, 25, and 35 defined transcriptome signatures for MGE and cIN cell identity. Further integration of these gene expression signatures with ChIP-seq for the NKX2-1 transcription factor in MGE-like progenitors defined NKX2-1 putative direct targets, including genes involved in both MGE specification and in several aspects of later cIN differentiation (migration, synaptic function). Among the NKX2-1 direct targets with MGE and cIN enriched expression was CHD2, a chromatin remodeling protein. Since CHD2 haploinsufficiency can cause epilepsy and/or autism, which can involve altered cIN development or function, we evaluated CHD2 requirements in these processes. Transcriptome changes were evaluated in CHD2 knockdown MGE-like progenitors at day 15, revealing diminished expression of genes involved in MGE specification and cIN differentiation including channel and synaptic genes implicated in epilepsy, while later cIN electrophysiological properties were also altered. We defined some shared cis-regulatory elements bound by both NKX2-1 and CHD2 and characterized their ability to cooperatively regulate cIN gene transcription through these elements. We used these data to construct regulatory networks underlying MGE specification and cIN differentiation and to define requirements for CHD2 and its ability to cofunction with NKX2-1 in this process. Overall design: To comprehensively define changes in gene expression profiles that accompany cortical interneuron (cIN) specification and differentiation process, we have performed RNA sequencing analysis at days 0 (hESCs), 4, 15, 25, and 35. To understand the gene regulatory networks through which NKX2-1 may directly control these processes, we defined its direct targets by performing NKX2-1 ChIP-seq in day 15 MGE-like cells. Chromatin enrichment for NKX2-1 binding was compared to input and IgG controls. To define the CHD2-dependent gene expression programs during cIN specification, we used CHD2 knockdown (KD) to conduct RNA-seq analysis in d15 CHD2 KD MGE-like cells.

Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Aims/hypothesis Due to their ability to regulate various signalling pathways (cytokines, hormones, growth factors), the suppressor of cytokine signalling (SOCS) proteins are thought to be promising therapeutic targets for metabolic and inflammatory disorders. Hence, their role in vivo has to be precisely determined.

Description
Growth of the drosophila eye imaginal discs is controlled by the activation of Notch in the dorsal-ventral boundary. Overexpression in the eye disc of the Notch ligand Delta together with lola and pipsqueak from the GS(2)88A8 line induces tumoral growth. We used microarray to analyze the expression profile of tumoral discs.
Publication Title

Description
Background: Gliomas are the most common type of primary brain tumours, and in this group glioblastomas (GBMs) are the higher-grade gliomas with fast progression and unfortunate prognosis. Two major aspects of glioma biology that contributes to its awful prognosis are the formation of new blood vessels through the process of angiogenesis and the invasion of glioma cells. Despite of advances, two-year survival for GBM patients with optimal therapy is less than 30%. Even in those patients with low-grade gliomas, that imply a moderately good prognosis, treatment is almost never curative. Recent studies have demonstrated the existence of a small fraction of glioma cells with characteristics of neural stem cells which are able to grow in vitro forming neurospheres and that can be isolated in vivo using surface markers such as CD133. The aim of this study was to define the molecular signature of GBM cells expressing CD133 in comparison with non expressing CD133 cells. This molecular classification could lead to the finding of new potential therapeutic targets for the rationale treatment of high grade GBM.

Molecular analysis of ex-vivo CD133+ GBM cells revealed a common invasive and angiogenic profile but different proliferative signatures among high grade gliomas.

Description
Atrial fibrillation (AF) is a major risk factor for cardioembolic stroke. Anticoagulant drugs are effective in preventing AF-related stroke. However, the high frequency of anticoagulant-associated major bleeding is a major concern particularly when antiplatelet treatment is simultaneously administered. Here, microarray analysis in peripheral blood cells in eight patients with AF and stroke and eight AF subjects without stroke identified a stroke related gene expression pattern. HSPA1B, which encodes for heat-shock protein 70 kDa (Hsp70), was the most differentially expressed gene. This gene was downregulated in stroke subjects, a finding confirmed further in an independent AF cohort of 200 individuals. Hsp70 knock-out (KO) mice subjected to different thrombotic challenges developed thrombosis significantly earlier than their wild-type (WT) counterparts.
Publication Title
Hsp70 protects from stroke in atrial fibrillation patients by preventing thrombosis without increased bleeding risk.

Description
To explore the primary cause of Dilated Cardiomyopathy in Bmi1-null mice, we set out to identify differentially expressed genes by massively parallel sequencing of heart samples from Bmi1f/f;aMHCTM-Cretg/+ mice versus aMHCTM-Cretg/+ control mice (17 weeks postinduction). Overall design: Methods: Heart mRNA profiles of 17-weeks post-induction Bmi1f/f; MHCTM-Cretg/+ mice and MHCTM-Cretg/+ control mice were generated by deep sequencing, in triplicate, using Illumina GAIIx. Sequence reads were pre-processed with Cutadapt 1.2.1, to remove TruSeq adapters and mapped on the mouse transcriptome (Ensembl gene-build GRCm38.v70) using RSEM v1.2.3. The Bioconductor package EdgeR was used to normalize data with TMM and to test for differential expression of genes using GLM.
