Project description:The genomic distribution of post-translationally modified histones in the zebrafish (Danio rerio) genome remain largely unraveled. The objective of this study was to (1) design a microarray covering all zebrafish gene promoters and 5' end of coding regions, and (ii) using these arrrays, map the genome-wide distribution of trimethylated H3K4 and H3K27 in the embryo derived ZF4 cell line. Specifically, we determined the enrichment profile of H3K4me3, H3K27me3 and of both (co-enriched) modifications in ZF4 cells. We determined average enrichment profiles through metagene analysis, functional terms enriched among genes marked by either modification, pathway analysis, and in relation to gene expression. Gene expression experiments were performed on three biological replicates.

Project description:MicroRNAs (miRNAs) play vital roles in various biological processes by leading to mRNA cleavage or translational repression, and are also involved in multiple stress conditions. However, the detailed roles of miRNAs in cold acclimation in fish are still unclear. In the present study, high-throughput sequencing was performed to identify miRNAs from 6 small RNA libraries from the zebrafish embryonic fibroblast ZF4 cells under control (28°C, 30 days) and cold-acclimation (18°C, 30 days) conditions. A total of 414 miRNAs, 349 known and 65 novel, were identified. Among those miRNAs, 24 (19 known and 5 novel) were up-regulated, and 23 (9 known and 14 novel) were down-regulated in cold acclimated cells. The Gene Ontology (GO) and Kyoto Encyclopaedia of Genes and Genomes (KEGG) enrichment analyses indicated that the known differentially expressed miRNAs (DE-miRNA) are involved in cold acclimation by regulation of phosphorylation, cell junction, intracellular signal transduction, ECM-receptor interaction and so on. Moreover, dre-miR-100-3p inhibitor or dre-miR-16b mimics could protect ZF4 cells under cold stress, indicating the involvement of miRNA in cold acclimation. In summary, the present data show that miRNAs are closely involved in cold acclimation in fish and provide information for further understanding of the roles of miRNAs in cold acclimation.

Project description:Zygotic genome activation (ZGA) occurs at the mid-blastula transition (MBT) in zebrafish and is a period of chromatin remodeling. Genome-scale gametic demethylation and remethylation occurs after fertilization, during blastula stages, but how ZGA relates to promoter DNA methylation states is unknown. Using methylated DNA immunoprecipitation coupled to high-density microarray hybridization (MeDIP-ChIP), we characterize genome-wide promoter DNA methylation dynamics before, during and after ZGA onset, in relation changes in post-translational histone modification and gene expression (Series GSE22830). A Kolmogorov-Smirnov (KS) test was applied with P <= 0.01 to identify methylation peaks. MeDIP-chip experiments were performed on24 hpf zebrafish embryos and sperm. Samples were lysed and proteins digested by proteinase k treatment. DNA was extracted with phenol-chloroform-isoamylalcohol and ethanol precipitation. The DNA was RNAse treated and sonicated to fragment lengths between 300-1000 bp. From each stage, duplicate immuneoprecipitations were performed using anti-5-methylcytosine antibody (10 ng/M-BM-5l; Mab-006-100; Diagenode) coupled to Dynabeads M-280 sheep anti-mouse IgG (Invitrogen). MeDIP and input DNA (150 ng each) were amplified (WGA-2; Sigma-Aldrich), cleaned up, eluted and processed for array hybridization. MeDIP and input DNA were labeled and co-hybridized onto the Nimbegen promoter arrays. The array covers 15 kb of upstream regulatory sequence and 5 kb downstream of the TSS of all zebrafish genes. A Kolmogorov-Smirnov (KS) test was applied with P <= 0.01 to identify methylation peaks.

Project description:Chronic pain is a global public health problem, but the underlying molecular mechanisms are not fully understood. Here we examine genome-wide DNA methylation, first in 50 identical twins discordant for heat pain sensitivity and then in 50 further unrelated individuals. Whole blood DNA methylation was characterized at 5.2 million loci by MeDIP-sequencing and assessed longitudinally to identify differentially methylated regions associated with high or low pain-sensitivity (pain-DMRs). Nine meta-analysis pain-DMRs show robust evidence for association (false discovery rate 5%) with the strongest signal in the pain gene TRPA1 (P=1.2M-CM-^W10-13). Several pain-DMRs show longitudinal stability consistent with susceptibility effects, have similar methylation levels in brain, and altered expression in skin. Our approach identifies epigenetic changes in both novel and established candidate genes that provide molecular insights into pain and may generalize to other complex traits. MeDIP-sequencing in 100 individulas using a 2 stage design: paired-end MeDIP-seq in 50 monozygotic twins and single-end MeDIP-seq in 50 unrelated individuals.

Project description:Methylated DNA immunoprecipitation sequencing (MeDIP-Seq) is a widely used approach to study DNA methylation genome-wide. Here, we present a novel MeDIP-Seq protocol compatible with the Ion Torrent semiconductor-based sequencing platform that is scalable and accurately identifies sites of differential DNA methylation. Additionally, we demonstrate that the high-throughput data derived from MeDIP-Seq on the Ion Torrent platform provides adequate coverage of CpG cytosines, the methylation states of which we validated at single-base resolution on the Infinium HumanMethylation450K Beadchip array. We applied this integrative approach to further investigate the role of DNA methylation in alternative splicing and to profile 5-mC and 5-hmC variants of DNA methylation in normal human brain tissue that we observed localize over distinct genomic regions. These applications of MeDIP-Seq on the Ion Torrent platform have broad utility and add to the current methodologies for profiling genome-wide DNA methylation states in normal and disease conditions.

Project description:Full pluripotency of induced pluripotent stem (iPS) cells has been determined as viable all-iPS mice can be generated through tetraploid complementation. Subsequently, activation of imprinted Dlk-Dio3 gene cluster has been suggested to correlate with the pluripotency of iPS cells1. However, evidence from recent studies has demonstrated that loss of imprinting at the Dlk-Dio3 locus did not correlate strictly with the reduced pluripotency of iPS cells. Therefore, it becomes indispensable to exploit other reliable molecular markers for evaluating the quality of iPS cells accurately. In the present study, we successfully utilize the sequential reprogramming approach and produce all-iPS mice to six generations using iPS cell lines derived from different cell lineages which contain the same proviral integration in the genome. By comparing the global gene expression and epigenetic modifications of both “tetra-on” and corresponding “tetra-off” iPS cell lines established from either mesenchymal or hematopoietic lineages through deep sequencing analysis of mRNA expression, small RNA profiling, histone modifications (H3K4m2, H3K4me3 and H3K27me3) and DNA methylation, very few differences are detected among all the iPS cell lines investigated. However, we find that two imprinted genes, disruption of which correlate with the reduced pluripotency of iPS cells. Therefore, our data not only provide the first demonstration that producing of all-iPS mice to six generations is feasible, but reveal that two imprinted regions can be served as pluripotency markers of iPS cells Examination of DNA methylation in 13 cell types

Project description:DNA methylation is critical for development and is strongly associated with gene regulation. Variation in the DNA methylome between closely related species may reveal unique functional adaptation. We have implemented a novel inter-primate DNA methylation genome-wide analysis between human, chimpanzee and rhesus macaque to identify human species-specific Differentially Methylated Regions (human s-DMRs) in orthologous loci. We analysed the peripheral blood cell DNA methylomes of these primates and identified 22,758 hypomethylated and 15,858 hypermethylated human s-DMRs. These s-DMRs are globally enriched within weak promoter, enhancer and transcribed regions via comparison with ChromHMM segmentation. Human s-DMRs, (both hypo- and hypermethylated) are found to be more prevalent in CpG Island shores than within the islands themselves (?2 P = 1.80 x 10-32). Examining human-specific Transcription Factor Binding Site motif change within CpG islands, we show gain and loss, in hypomethylated and hypermethylated s-DMRs, respectively, of CTCF motifs. Epigenetically the most divergent human-specific locus was the immunological Leukotriene B4 receptor (LTB4R, aka BLT1 receptor), due to collocating hypomethylated s-DMRs within the promoter CpG island and shore, as well as inverse increased gene body methylation. This gene is vital in host immune responses and associated with the pathogenesis of a wide range of human inflammatory diseases. This finding was supported by additional neutrophil-only DNA methylome and lymphoblastoid H3K4me3 chromatin comparative data. Functional investigation of the consequences of these epigenetic differences identified this receptor to have increased expression, and have a higher response to the LTB4 ligand in human versus rhesus macaque peripheral blood mononuclear cells. This result further emphasises the exclusive nature of the human immunological system, its divergent adaptation even from closely related primates, and the power of comparative epigenomics to identify and understand human uniqueness.

Project description:Somatic cell nuclear transfer has brought considerable chances to breed excellent breeds and protect endanger animals, while also produced numerous fail embryos and abnormal individuals due to inefficient epigenetic modification at the same time. To understand some mechanisms of abnormal piglets with phenotypes such as macroglossia, standing and walking disabilities in our study and find some differences between abnormal piglets and conventionally bred normal piglets, DNA methylation profile and genome-wide gene expression were conducted in two groups, using methylated DNA immunoprecipitation binding highthroughput sequencing (MeDIP-Seq) and RNA sequencing(RNA-Seq). We generated and provided a genome-wide DNA methylation and gene expression profile for abnormal cloned and conventionally bred piglets. We detected a total of 1493 genes differentially expressed in two groups and 382 of these genes also differentially methylated in two groups. Analysis of relationship between DNA methylation and gene expression revealed that DNA methylation levels had significantly negative and monotonic correlation with gene expression levels in particular regions of genes while no obvious monotonic correlation in other regions. Besides, we found some interesting genes and pathways such as MYH7 and mTOR signalling pathway that may played essential role in muscle growth and development. Briefly, these results provide reliable data for future epigenetic studies and may help to uncover the mechanism of failure clones via SCNT. We dissected the leg muscle from the cloned piglets and the conventionally bred piglets, and analyzed the difference of MeDIP-seq and RNA-seq between the two groups. As for data of abnormal cloned piglets, we downloaded it from GEO under Super-Series accession No. GSE51477, including SubSeries accession No.GSE51282 for RNA-seq data (No. GSM1241829 for abnormal cloned group) and SubSeries accession No. GSE51476 for MeDIP-seq data (No. GSM1246252 for abnormal cloned group).
