Genome-wide binding profiles of nuclear FGFR1, RXR? and Nur77 in pluripotent mouse Embryonic Stem Cells and during Retinoic Acid-induced differentiation

ABSTRACT: We report the genome-wide binding patterns of nuclear FGFR1, RXR? and Nur77 in pluripotenet mESC and as mESC differentiate towared a neuronal lineage in response to high levels of Retinoic Acid treatment in vitro. We also report the genome-wide incorporation of histone varant H3.3 into chromatin specifically during Retinoic Acid-induced differentiation. This study presents nuclear FGFR1 as a global factor that controls genomic function by binding within the promoters of thousands of genes, both alone and in cooperation with RXR, Nur77 and histone H3.3, by targeting consensus DNA sequences of diverse transcription factor families. As such, it identifies a previously unknown, multifaceted form of control of major ontogenic pathways and gene networks targeted by the nuclear form of FGFR1. Examination of nuclear FGFR1, RXR?, and Nur77 binding sites in 2 celluar states. Examination of H3.3 incorporation in 1 cellular state.

Genome-wide microRNA transcriptome profiles in pluripotent mouse Embryonic Stem Cells and during Retinoic Acid-induced differentiation

Project description:We report the genome-wide microRNA expression levels in pluripotent mESC and as mESC differentiate towards a neuronal lineage in response to high levels of Retinoic Acid treatment in vitro. microRNA-seq was performed to identify all microRNAs expressed in both ESCs and neuronal cells. In total, 534 expressed microRNAs we identified, of which 18 were up-regulated and 6 were down-regulated (fold change (FC) > -/+2.0 and p-value < 0.05) during Retinoic Acid-induced neuronal differentiation. The top up-regulated microRNAs identified were Mir10a, Mir615, Mir217 and Mir219a-2. The top down-regulated microRNAs identifed were Mir211, Mir292, Mir302a and Mir302c. Examination, identification and comparision of microRNA expression profliles in two cellular states.

RNA-seq of H3.3K4A/K36A mutant ESCs and neurons

Project description:Study to investigate the role of histone residues H3K4 and H3K36 for gene expression, histone localization and neuronal lineage specification by mutation of K4 and K36 in H3.3 to alanine. Histone variant H3.3 differs from the canonical H3.1/H3.2 by only 4 to 5 amino acids, which are necessary for nucleosome assembly independent of DNA replication, and is encoded by two gene copies. Complete loss of the two H3.3 genes (H3f3a and H3f3b) leads to embryonic lethality while single gene knockout yields viable mice. We used CRISPR-Cas9 to delete H3f3a and introduce homozygous point-mutations into H3f3b, thus ensuring that the entire pool of H3.3 protein carries the mutation of interest. We differentiated H3.3ctrl (H3f3a knock-out; H3f3b wild type), H3.3K4A mutant (H3f3a knock-out; H3f3b K4A) and H3.3K36A mutant (H3f3a knock-out; H3f3b K36A) ESCs into glutamatergic neurons. Gene expression profiles were measured by mRNA-Sequencing in undifferentiated ESCs (D0), neurodevelopment (D8) and differentiated neurons (D12) to assess the impact of the mutation on gene expression and development.

RNA-seq was performed to identify all RNAs expressed in both ESCs and neuronal cells. In total, In total, 14,443 expressed genes were detected, of which 1,834 were up-regulated and 1,477 down-regulated (fold change (FC) > -/+2.0 and p-value < 0.035) during RA-induced neuronal differentiation. The top down-regulated genes included members of the pluripotency core transcriptional network, including Klf4, Sox2, Oct4, Nanog, Suz12, Esrrb, Stat3 and Tcfcp2l1. The top up-regulated genes are important for neuronal differentiation (e.g. Pax3, Irx3, Rest and Foxd3) and reside in the RA-pathway (e.g. various homeobox genes), the retinoic acid receptors and the RA-degradation enzyme Cyp26a1. Examination, identification and comparision of mRNA expression profliles in two cellular states.

Foxd3 promotes the exit from naïve pluripotency and prevents germline specification through enhancer decommissioning [RNA-Seq]

Project description:Following implantation, mouse epiblast cells transit from a naïve to a primed state in which they are competent for both somatic and primordial germ cell (PGC) specification. Using mouse embryonic stem cells (mESC) as an in vitro model to study the transcriptional regulatory principles orchestrating peri-implantation development, here we show that the transcription factor Foxd3 is necessary for the exit from naïve pluripotency and the progression to a primed pluripotent state. During this transition, Foxd3 acts as a repressor that dismantles a significant fraction of the naïve pluripotency expression program through the decommissioning of active enhancers associated with key naïve pluripotency and early germline genes. Subsequently, Foxd3 needs to be silenced in primed pluripotent cells to allow the reactivation of relevant genes required for proper PGC specification. Our findings uncover a wave of activation-deactivation of Foxd3 as a crucial step for the exit from naïve pluripotency and subsequent PGC specification. mRNA profiles were generated by RNA-seq in duplicates for each of the following mESC lines: Foxd3fl/fl;Cre-ER mESC maintained in "Serum+LIF" (SL) treated with TM for three days (SL Foxd3-/-); untreated Foxd3fl/fl;Cre-ER SL mESC (SL Foxd3fl/fl); tetON Foxd3 SL mESC treated with Dox for three days; WT SL mESC treated with Dox for three days; Foxd3fl/fl;Cre-ER mESC maintained in "2i+LIF" (2i) treated with TM for three days (2i Foxd3-/-); untreated Foxd3fl/fl;Cre-ER 2i mESC (2i Foxd3fl/fl).

ChIP-seq of H3.3K4A/K36A mutant ESCs and neurons

Project description:Study to investigate the role of histone residues H3K4 and H3K36 for gene expression, histone localization and neuronal lineage specification by mutation of K4 and K36 in H3.3 to alanine.

Genomic localization of H3.3 protein was determined by ChIP-Sequencing in ESCs (D0). Histone modifications patterns of H3K4me1, H3K4me3 and H3K27ac were measured by ChIP-Sequencing in ESCs (D0) to assess the impact of the H3.3K4A mutation on the epigenetic landscape. Levels of H3K36me3 were measured by ChIP-Sequencing in WT and H3.3K36A mutant ESCs (D0), NPCs (D8) and neurons (D12) to assess the impact of the H3.3K36A mutation on H3K36me3 levels in development.

Genome-wide incorporation dynamics reveal distinct categories of turnover for the histone variant H3.3

Project description:We developed a system to study the DNA replication-independent turnover nucleosomes containing the histone variant H3.3 in mammalian cells. By measuring the genome-wide incorporation of H3.3 at different time points following epitope-tagged H3.3 expression, we find three categories of H3.3-nucleosome turnover in vivo: rapid turnover, intermediate turnover and, specifically at telomeres, slow turnover. Our data indicate that H3.3-containing nucleosomes at enhancers and promoters undergo a rapid turnover that is associated with active histone modification marks including H3K4me1, H3K4me3, H3K9ac, H3K27ac and the histone variant H2A.Z. The rate of turnover is negatively correlated with H3K27me3 at regulatory regions and with H3K36me3 at gene bodies. Examination of incorporation dynamics of histone variant H3.3

Nuclear receptor Nur77 and Yin-Yang 1 synergistically increase mitochondrial abundance and activity in macrophages [RNA-seq]

Project description:Mitochondrial biogenesis requires precise regulation of both mitochondrial-encoded and nuclear-encoded genes. Nuclear receptor Nur77 is known to regulate mitochondrial metabolism in macrophages and skeletal muscle cells. Here, we compared genome-wide Nur77 binding site and target gene expression in these two cell types, which revealed conserved roles for this nuclear receptor in the regulation of nuclear-encoded mitochondrial ribosomal proteins (MRP) and enrichment of motifs for the transcription factor Yin-Yang 1 (YY1). We show that Nur77 and YY1 interact, that YY1 increases Nur77 activity, and that their binding sites are co-enriched at MRP gene loci. Nur77 and YY1 co-expression synergistically increases mitochondrial abundance and activity in macrophages but not skeletal muscle. As such, we identify a macrophage-specific Nur77-YY1 interaction that enhances mitochondrial metabolism.
