Epigenomic landscape during organ formation in human early embryos

ABSTRACT: Here we present the whole genome ChIP-Seq analyses of a wide variety of histone marks, H3K27ac, H3K4me1, H3K4me3, and H3K27me3 in the brain, heart, and liver, along with the RNA-seq data of these organs of early human embryos 12 weeks after gestation. In total, brain, heart, and liver of early human post-implantation embryos were used, and four histone modifications were detected, including H3K27ac, H3K4me1, H3K4me3 and H3K27me3. Also, the transcriptomes of these three organs were analyzed.

The epigenetic regulation of spatiotemporal gene expression is crucial for human development. Here, we present whole-genome chromatin immunoprecipitation followed by high throughput DNA sequencing (ChIP-seq) analyses of a wide variety of histone markers in the brain, heart, and liver of early human embryos shortly after their formation. We identified 40,181 active enhancers, with a large portion showing tissue-specific and developmental stage-specific patterns, pointing to their roles in control ...[more]

Enhancer-associated H3K4 mono-methylation by Drosophila Trithorax-related, the Drosophila homolog of Mll3/Mll4

Project description:Mono-methylation of histone H3 on lysine 4 (H3K4me1) and acetylation of histone H3 on lysine 27 (H3K27ac) are histone modifications that are highly enriched over the body of actively transcribed genes and enhancers. Although in yeast all H3K4 methylation patterns including H3K4me1 are implemented by Set1/COMPASS, there are three classes of COMPASS-like complexes in Drosophila that could carry out H3K4me1 on enhancers: dSet1, Trithorax and Trithorax-related (Trr). Here, we report that Trr, the Drosophila homolog of mammalian Mll3/4, can function as a major H3K4 mono-methyltransferase on enhancers in vivo. Loss of Trr results in a global decrease of H3K4me1 and H3K27ac in various tissues. Assays with the cut wing margin enhancer imply a functional role for Trr in enhancer-mediated processes. A genome-wide analysis demonstrates that Trr is required for H3K4me1 and H3K27ac on chromatin signatures that resemble the histone modification patterns described for enhancers. Since Trr and mammalian Mll3/4 complexes are distinguished by bearing a unique subunit, the H3K27 demethylase UTX, we propose a model in which the H3K4 mono-methyltransferase Trr, and the H3K27 demethylase, UTX, cooperate to regulate the transition from inactive/poised to active enhancers.

H3K4me1 distribution at promoters predicts the poised epigenetic state

Project description:Post-translational modifications on histone tails are closely correlated to transcriptional states. One such modification is monomethylation on lysine 4 of histone 3(H3K4me1), a mark that has been linked to enhancers. Identifying regions enriched for H3K4me1 and depleted in H3K4me3, or regions enriched for both H3K4me1 and H3K27ac, has proven to be a feasible enhancer discovery method. At the same time, not all H3K4me1-enriched regions correspond to enhancers. H3K4me1 marks also exist at promoters, which implies that the H3K4me1 modification may have a context-dependent role in regulating transcription. We report distinct patterns of H3K4me1 that predict transcriptional regulatory states at promoters in germ cells and ESCs. We examined ChIP-seq data for H3K4me1, H3K4me3, H3K27me3, and H3K27ac in mouse and human male germ cells, and found that H3K4me1 peak density around the transcription start sites (TSS) exhibits either a broad bimodal profile or a narrower unimodal profile centered at the TSS. We then examined the position of the H3K4me1 marks relative to H3K4me3, and found that unimodal H3K4me1 directly at the TSS predicts a poised (H3K4me1/H3K27me3 bivalent) state of chromatin, while bimodal H3K4me1 flanking the TSS predicts an active state. We conclude that unimodal H3K4me1 centered on the TSS is a characteristic feature of the poised epigenetic state in ESCs and germ cells. Note: H3K4me1 and H3K27ac data are included in this GEO accession; H3K4me3 and H3K27me3 were released in GSE68507.
