Chip-seq of H3K4me3, H3K4me1, H3K27ac and P300 in HCC cells

ABSTRACT: Considered as fundamental epigenetic regulators controlling many key cellular processes, histone modifications are a well-conserved and widely studied class of epigenetic modifications. Genome-wide studies have identified enhancers as DNA sequences that bind to H3K4me1 and H3K27ac and promoters as DNA sequences that bind to H3K4me3. To explore how the Twist1 complex (Twist1/YY1/p300) regulates miR-9 expression, we performed ChIP-seq in PLC-PRF-5 cells, providing a panorama of p300, H3K4me3, H3K4me1, and H3K27ac.

Enhancer divergence and cis-regulatory evolution in the human and chimpanzee neural crest

Project description:Here we derive human and chimpanzee cranial neural crest cells (CNCCs) and profile histone modifications, transcription factors, chromatin accessibility and gene expression to systematically and quantitatively annotate evolutionary divergence of craniofacial cis-regulatory landscapes. Histone modifications (H3K27ac, H3K4me1, H3K4me3, H3K27me3), chromatin modifiers (p300), transcription factors (NR2F1, TFAP2A), chromatin accessibility (ATACseq) and gene expression (RNAseq) were assayed in CNCCs derived from iPSCs/ESCs from 2 chimpanzee and 3 human individuals.

Enhancer chromatin signatures predict Smad2/3 binding in Xenopus

Project description:In this study we have examine the deposition of H3K4me1,H3K4Me3 and H3K27Ac and the Nodal transcription factor, Smad2/3, immediately following zygotic transcription and continuing through gastrulation. We profiled 4 histone modifications (H3K4Me3, H3K27Me3, H3K27AC, H3K4Me1) and one transcription factor smad2/3 (+ chromatin input) using ChIP-Seq, and expression profiles (3' RNA-Seq) for Xenopus tropicalis embryos stage8, stage9 and stage10.5. Furthermore, we have profile two histone modifications (H3K4Me1 and H3K27Ac) in absance of nodal signaling in stage9 Xenopus tropicalis embryos using ChIP-seq and 3-seq

Epigenomic landscape during organ formation in human early embryos

Project description: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.

ATAC-seq profiling of open chromatin in PLC-PRF cells

Project description:Epithelial–mesenchymal transition (EMT) is an important mechanism of metastasis and malignant progression of hepatocellular carcinoma (HCC). However, the transcriptional regulation mechanism of EMT remains poorly understood. Some transcriptional co-activators can form phase-separated condensates at super-enhancers that compartmentalize and concentrate the transcription apparatus to drive robust gene expression. Here, we demonstrate that Twist1 and YY1, interact with p300 and form phase-separated local high-concentration interaction hubs at super-enhancers of miRNA-9 and activate its expression to induce EMT and promote the malignant evolution of HCC. Phase separation disrupted by metformin perturbs Twist–YY1 condensates, thereby inhibiting EMT. To explore how the Twist1 complex regulates miR-9 expression by binding SE region, we performed Twist1 ChIP-seq combined with H3K4me3, H3K4me1, H3K27ac, DNAse, p300, and YY1 ChIP-seq data to detect the SEs of miR-9. After metformin treatment, the peak of Twist1/YY1 on miR-9 SE decreased. Metformin specifically affects the binding of Twist1/YY1 to the miR-9 SE region. 1,6-hexanediol, as an aliphatic alcohol, can weaken hydrophobic interactions and inhibit liquid–liquid phase separation by disrupting hydrophobic interactions. In order to prove Twist1/YY1 interaction at these sites requires phase separation, we detect the accessibility of miR-9 SE regions in 1,6-hexanediol-treated cells. The result showed a general decrease in the accessibility of miR-9 super-enhancer regions in 1,6-hexanediol-treated cells and Twist1 / YY1 combines the SE region of miR-9 in the form of phase separation.
