Eomes and Brachyury control pluripotency exit and germ-layer segregation by changing the chromatin state

ABSTRACT: We aimed to elucidate molecular mechanisms of first lineage decision in the mouse pluripotent epiblast that segregates mesoderm and endoderm (ME) from neuroectoderm (NE). By analyzing mouse embryonic stem cells (ESCs) and embryos deficient for two T-box (Tbx) transcription factors Eomes and Brachyury we demonstrate that this process is controlled by the changes in the chromatin accessibility of ME gene enhancers and activation of the target genes, but also direct repression the opposing pluripotency and NE gene programs.

The molecular basis of specific functions of Brachyury and Eomes for mesoderm and endoderm lineage specification

Project description:The Tbx factors Eomesodermin (Eomes) and Brachyury instruct endoderm and mesoderm specification. Both Tbx factors have common large overlap in chromatin binding sites, however their embryonic phenotypes of mutants largely differ. In this study, we delineate the distinct binding patterns and gene target sets of Eomes and Brachyury providing a molecular model of distinct fate specification programs.

EOMES establishes mesoderm and endoderm differentiation potential through SWI/SNF-mediated global enhancer remodeling [ChIP-Seq]

Project description:In this study we analysed the dynamic changes in the epigenetic landscape during first embryonic lineage decision following pluripotency exit. Here, mouse pluripotent epiblast cells segregate towards mesoderm and endoderm (ME) or neuroectoderm (NE). The analysis of chromatin accessibility, histone modifications and accompanied gene expression confirmed a bias of the epigenetic landscape towards NE fate while ME cis regulatory elements (CREs) are becoming accessible and active during lineage specification. We show that the default state of NE differentiation is actively overcome by the activity of the Tbx transcription factor (TF) EOMES binding to closed ME CREs. We found the ATP-dependent chromatin remodelling complex SWI/SNF is recruited by EOMES to target ME enhancers. The recruitment of the complex by EOMES leads to the remodelling of the enhancer landscape at ME genes. The ME enhancer landscape is remodelled by the activity of EOMES independent on gene expression genome wide.

Primary cilium-autophagy-Nrf2 (PAN) axis links the cell cycle to neuroectoderm fate in human embryonic stem cells

Project description:Under defined differentiation conditions human embryonic stem cells (hESCs) can be directed toward a mesendodermal (ME) or neuroectoderm (NE) fate, the first decision during hESC differentiation. Coupled with G1 lengthening a divergent ciliation pattern emerged within the first 24 hours of induced lineage specification and these changes heralded a neuroectoderm decision before any neural precursor markers were expressed. By day 2, increased ciliation in NE precursors induced autophagy that resulted in the inactivation of Nrf2. Nrf2 binds directly to upstream regions of the OCT4 and NANOG genes to promote their expression and represses NE derivation. Nrf2 suppression was sufficient to rescue poorly neurogenic iPSC lines. Only after these events have been initiated do neural precursor markers get expressed at day 4. Thus we have identified a primary cilium-autophagy-Nrf2 (PAN) axis coupled to cell cycle progression that directs hESCs toward NE.

Map Brachyury-bound enhancers by ChIP-seq

Project description:To gain new mechanistic insights into highly-regulated lineage specification and morphogenetic processes during early embryogenesis, we applied ChIP-seq to identify transcriptional programs mediated by a key developmental regulator - Brachyury. Embryonic stem cells were differentiated into Brachyury-positive mesoendoderm cells. And, ChIP-seq experiments were carried out by two independent Brachyury antibodies.

Genome wide maps of H3K4me3, H3K27me3 and H3K27ac in Brachyury mutants and RNA-seq data of Brachyury mutants

Project description:The transcription factor BRACHYURY is the founding member of the T-box family of proteins. A conserved residue (Y88 in BRACHYURY) was previously suggested to be important for interaction with KDM proteins that demethylate H3K27me3. We generated Brachyury mutant mouse embryonic stem cell (ESC) lines. For a wild type control (Thet) we derived an embryonic stem cell line from blastocysts, containing a single wild type copy of the Brachyury locus (T +/2J; 2J is a large genomic deletion of the entire Brachyury locus). We mutated the remaining wild type copy of Brachyury to code for Alanin instead of the conserved tyrosine (Y88) residue (T_Y88A). We derived embryos from these ESCs, compare expression profiles (RNAseq) from Thet and TY88A caudal end mesoderm of early embryos (stages: TS12 and TS13), and complement the expression data with histone methylation ChIPseq data for H3K4me3, HeK27me3 and H3K27ac. Of note: due to the different requirements of cellular material for RNAseq and ChIPseq we differentiated the same ESC used for the embryo generation (in vivo, RNA-seq) to generate early caudal end mesoderm in vitro (ChIPseq). In addition, this dataset contains a ChIPseq track for BRACHURY in wild type ESCs, differentiated into early mesoderm in vitro with the same protocol as for the histone ChiIPseq.
