Project description:We report the application of ChIP-sequencing technology for high-throughput profiling of histone modifications in budding yeast. By obtaining over four billion bases of sequence from chromatin immunoprecipitated DNA, we generated genome-wide maps of Set1 and H3K4me3 in yeast cells. We find that Set1 and H3 lysine 4 trimethylation locate primarily in open reading frame of genes. In addition, we focus on the distribution of Set1 and H3K4me3 in histone gene clusters and found strong similar binding of Set1 and H3K4me3 on all histone genes.

Project description:Purpose: In lung tissue of mice with experimental PH, we identified an upregulated lncRNA 5031425E22 which mapped to a human ortholog KMT2E-AS1. Across mammals, this lncRNA gene sits adjacent (head-to-head) to the chromosomal location of the histone lysine N-methyltransferase 2E gene (KMT2E), a member of a family of regulators controlling histone 3 lysine 4 trimethylation (H3K4Me3) and chromatin remodeling. We found that both mouse lncRNA E22 and human KMT2E-AS1 were increased in multiple in vivo rodent and human instances of PH. This ChIP-sequencing study was designed to compare the histone 3 lysine 4 methylated regions/gene profile of human pulmonary arterial endothelial cells (HPAECs) under hypoxia as compared to normoxia. Method: Primary HPAECs were grown in EBM-2 basal medium supplemented with EGM-2 MV BulletKit (Lonza). Experiments were performed at passages 5 to 8. Cultured HPAECs were either under normoxia or hypoxia (0.2% oxygen) for 24 hours. Cells were fixed, crosslinked, and sonicated to get soluble chromatin for immunoprecipitation. 10% input of crosslinked DNA was saved while the remining DNA was precipitated with histone 3 lysine 4 antibody (H3K4Me3, Abcam, ab8580) or non-immune rabbit IgG (Pierce magnetic ChIP kit). Chromatin/antibody complex was then pulled down using Protein A/G Magnetic Beads (Pierece). DNA samples were proceeded with ChIP-sequencing (sequencing platform: DNBSeqTM, 20M reads).

Project description:Histone acetylation and methylation regulate gene expression in eukaryotes, but their effects on the transcriptome of a multicellular organism and on the transcriptomic divergence between species are still poorly understood. Here we present the first genome-wide 1-bp resolution maps of histone acetylation, histone methylation and core histone in Arabidopsis thaliana and a comprehensive analysis of these maps and gene expression data in A. thaliana, A. arenosa and allotetraploids. H3K9 acetylation (H3K9ac) and H3K4 trimethylation (H3K4me3) are correlated, and their high densities near transcriptional start sites determine constitutive expression of genes involved in translation. In contrast, broad distributions of these modifications toward coding regions determine expression variation, especially in genes involved in photosynthesis, carbohydrate metabolism, and defense responses. A dispersed distribution of H3K27me3 and depletion of H3K9ac and H3K4me3 are associated with developmentally repressed genes. Finally, genes affected by histone deacetylase mutation and species divergence tend to show high expression variation. In conclusion, changes in histone acetylation and methylation modulate developmental and environmental gene expression variation within and between species. ChIP-Seq: Identification of distribution of H3K9ac, H3K4me3 and H3 in Arabidopsis thaliana leaf. Expression: Gene expression in the histone deacetylase 1 mutant was generated using t-DNA insertion. mRNA expressions in leaf and flower of the AtHD1 mutant were compared with those of the wild type plants. We conducted 8 replicates of dual-channel microarrays, including 4 biological replicates and individual dye swaps.

Project description:Reprogramming of histone modification regulates gene expression and mammal preimplantation development. Trimethylation of lysine 4 on histone 3 (H3K4me3) has unique landscape in mouse oocytes and early embryos. However, the dynamics and function of H3K4me3 in livestock embryos remain unclear. To address how it is reprogrammed in domestic animals, we profiled changes of H3K4me3 during bovine early embryo development. Notably, the overall signal of H3K4me3 decreased during embryonic genome activation (EGA). By utilizing ultra-low-input native ChIP-seq (ULI-NChIP-seq) technology, we observed widespread broad H3K4me3 domains in oocytes and embryos. The signal of broad H3K4me3 began to decrease after fertilization and was lowest after EGA. Along with the removal of broad H3K4me3, deposition of H3K4me3 at promoter regions enhanced gradually. Besides, the transcriptional activity and signal of promoter H3K4me3 showed positive correlation after the erasure of broad H3K4me3 at 16-cell stage. Moreover, knocking down of demethylases KDM5A, KDM5B and KDM5C caused EGA delay and blastocyst formation failure. RNA-seq analysis revealed 47.8% down-regulated genes in knockdown embryos at 8/16-cell stage were EGA genes, and 63.1% of up-regulated genes were maternal transcripts. Particularly, the positive correlation between transcriptional activity and promoter H3K4me3 during EGA was restrained when knocking down of KDM5A, KDM5B and KDM5C. Overall, our work initiatively mapped the genomic reprogramming of H3K4me3 during bovine preimplantation development, and KDM5A/B/C played roles in modulating oocyte-to-embryonic transition (OET) through timely erasure of broad H3K4me3 domains far away from promoters.
