Genome-wide view of TGFb/Foxh1 regulation of the early mesendoderm program [ChIP-seq]

Project description:We defined the genome-wide binding regions of Smad2/3 and Foxh1 at mid-gastrula stage Xenopus tropicalis embryos, at which Nodal signaling and Foxh1 are critical in mesendoderm specification program.

Identification of differentially-expressed genes between FoxH1 morpholino and control in zebrafish embryos.

Project description:The Forkhead Box H1 (FoxH1) protein is a co-transcription factor recruited by phosphorylated Smad2 downstream of several TGFbetas, including Nodal-related proteins. We have reassessed the function of zebrafish FoxH1 using antisense morpholino oligonucleotides (MOs) ( 5’ TGCTTTGTCATGCTGATGTAGTGGG 3’) as compared with a control morpholino (MO) with no specific target (5’ TAGTTAAGCCTAGCTCTCATAAACT 3’). Probing FoxH1 morphant RNA by microarray, we identified a cohort of five keratin genes – cyt1, cyt2, krt4, krt8 and krt18 - that are normally transcribed in the embryo’s enveloping layer (EVL) and which have significantly reduced expression in FoxH1-depleted embryos. Keywords: 40% epiboly-stage embryos, injected with either 8 ng of a 25mer morpholino (MO) with no specific target or 8 ng of a 25mer MO with reverse complementary to the 5’ untranslated region of the zebrafish foxH1 gene.

Foxh1 marks the embryonic genome prior to the activation of the mesendoderm gene regulatory program

Project description:We examined the binding dynamics of the maternal TF Foxh1 over a time course of germ layer development. Foxh1 binding was compared to the onset of zygotic transcription (RNA pol II), binding of the co-repressor Tle, Nodal signaling (Smad2/3) and the zygotic endoderm TF Foxa.

HEB and E2A function as SMAD/FOXH1 cofactors

Project description:Nodal signaling, mediated through SMAD transcription factors, is necessary for pluripotency maintenance and endoderm commitment. We have identified a new motif, termed SMAD Complex Associated (SCA) that is bound by SMAD2/3/4 and FOXH1 in human embryonic stem cells (hESCs) and derived endoderm. We demonstrate that two bHLH proteins - HEB and E2A - bind the SCA motif at regions overlapping SMAD2/3 and FOXH1. Further, we show that HEB and E2A associate with SMAD2/3 and FOXH1, suggesting they form a complex at critical target regions. This association is biologically important, as E2A is critical for mesendoderm specification, gastrulation, and Nodal signal transduction in Xenopus tropicalis embryos. Taken together, E2A is a novel Nodal signaling cofactor that associates with SMAD2/3 and FOXH1 and is necessary for mesendoderm differentiation. ChIP-seq of Smad2/3 and Input in X.tropicalis, stage 10.5 embryo.

Genome-wide analysis of Smad2 and FoxH1 binding sites in zebrafish blastula

Project description:Morphogen gradients expose cells to different signal concentrations and induce target genes with different ranges of expression. To determine how the Nodal morphogen gradient induces distinct gene expression patterns during zebrafish embryogenesis we characterized the binding sites of the Nodal-specific transcription co-activators Smad2 and FoxH1 in wild-type, Nodal-overexpressing or Nodal signaling inhibited embryos. We found that FoxH1 binds to Nodal targets loci even in the absence of the signal, while Smad2 only binds and colocalizes to FoxH1 upon induction of the Nodal pathway.

Foxh1/nodal defines context-specific direct maternal Wnt/Beta-catenin target gene regulation in early development

Project description:This study aimed to further understand context-specific direct Wnt target gene expression through the use of beta-catenin and FoxH1 ChIP Sequencing data at various developmental stages representing both maternal and zygotic Wnt signalling. Results were further supported through the use of RNA sequencing data from beta-catenin, FoxH1 and nodal gene knock down assays.

Genome-wide view of TGFβ/Foxh1 regulation of the early mesendoderm program.

Project description:Nodal/TGFβ signaling regulates diverse biological responses. By combining RNA-seq on Foxh1 and Nodal signaling loss-of-function embryos with ChIP-seq of Foxh1 and Smad2/3, we report a comprehensive genome-wide interaction between Foxh1 and Smad2/3 in mediating Nodal signaling during vertebrate mesendoderm development. This study significantly increases the total number of Nodal target genes regulated by Foxh1 and Smad2/3, and reinforces the notion that Foxh1-Smad2/3-mediated Nodal signaling directly coordinates the expression of a cohort of genes involved in the control of gene transcription, signaling pathway modulation and tissue morphogenesis during gastrulation. We also show that Foxh1 may function independently of Nodal signaling, in addition to its role as a transcription factor mediating Nodal signaling via Smad2/3. Finally, we propose an evolutionarily conserved interaction between Foxh1 and PouV, a mechanism observed in Pou5f1-mediated regulation of pluripotency in human embryonic stem and epiblast cells.

Engagement of Foxh1 in chromatin regulation revealed by protein interactome analyses

Project description:Precise gene expression patterns, both in time and space, is required for developmental processes to properly progress. Early embryonic cell fates are specified through the coordinated integration of transcription factor activities and epigenetic states of the genome. Foxh1 is a key maternal transcription factor controlling the mesendodermal gene regulatory program. Proteomic interactome analyses using FOXH1 as a bait in mouse embryonic stem cells revealed that FOXH1 interacts with PRC2 subunits and Hdac1. Foxh1 physically interacts with Hdac1, and confers transcriptional repression of mesendodermal genes in the ectoderm. Our findings reveal a central role of Foxh1 in coordinating the chromatin states of the Xenopus embryonic genome.
