GEO DataSets

(Submitter supplied) We mapped DNA methylation in 580 animal species (535 vertebrates, 45 invertebrates), resulting in 2443 genome-scale, base-resolution DNA methylation profiles of primary tissue samples from various organs. Reference-genome independent analysis of this comprehensive dataset defined a “genomic code” of DNA methylation, which allowed us to predict global and locus-specific DNA methylation from the DNA sequence within and across species. more...

(Submitter supplied) Comparative analysis of the oyster DNA methylomes and that of other animal species revealed that the characteristics of DNA methylation were generally conserved during invertebrate evolution, while some unique features were derived in the insect lineage. The preference of methylation modification on genes originating in the eukaryotic ancestor rather than the oldest genes is unexpected, probably implying that the emergence of methylation regulation in these 'relatively young' genes was critical for the origin and radiation of eukaryotes.

(Submitter supplied) Here we provided the first single-base resolution DNA methylatome in chicken lungs by whole-genome bisulfite sequencing (MethylC-seq). In addition, two genetically distinct highly inbred chicken lines, Leghorn and Fayoumi, were used to examine how DNA methylation regulates mRNA gene expression between two lines. The methylation profile demonstrated that methylcytosines in the chicken were more likely to occur in CG dinucleotides than in non-CG sites. more...

(Submitter supplied) Cytosine DNA methylation is a heritable epigenetic mark present in most eukaryotic groups. While the patterns and functions of DNA methylation have been extensively studied in mouse and human, their conservation in other vertebrates remain poorly explored. In this study, we interrogated the distribution and function of DNA methylation in primary cells of seven vertebrate species including bio-medical models and key livestock species.

(Submitter supplied) DNA methylation has been found throughout animal kingdom, but it is still unclear whether this epigenetic mechanism affects the evolution of genomic elements in animals. Here, we compare the DNA methylomes of gametes and embryos from 7 representative animal species. We find that parental methylomes are propagated to the progeny without significant changes during embryogenesis in cnidarians and insects, but undergo substantial reprogramming in echinoderms, and the reprogramming become more dramatic during deuterostome evolution. more...

(Submitter supplied) The brain requires complex mechanisms of genome regulation to encode and store behavioural information. In mammals, DNA methylation deposited at non-CG dinucleotides characterises brain epigenomes. However, it is unclear to what extent this non-canonical form of DNA methylation is evolutionarily conserved. To test this we profile brain cytosine methylation across the major vertebrate lineages, amphioxus, honeybee and octopus, finding that non-CG methylation in adult brain methylomes is restricted to vertebrates. more...

(Submitter supplied) Human embryonic stem cells (hESCs) are offering a new therapeutic approach because of their unique ability to proliferate indefinitely in vitro and differentiate into multiple cell types. However, our understanding of the molecular mechanisms of pluripotency and self-renewal remain incomplete. To elucidate the key regulatory sequences and genes responsible for these cellular properties, we have determined potential enhancers and insulators in the genome of human ES cells and examined the dynamics of four key chromatin modifications (H3K4me1, H3K4me3, H3K27ac and H3K27me3) at both promoters and enhancers during the differentiation of these cells. more...

(Submitter supplied) Human embryonic stem cells share identical genomic sequences with other lineage-committed cells yet possess the remarkable properties of self-renewal and pluripotency. It has been proposed that epigenetic regulatory mechanisms, involving DNA methylation and various chromatin modifications, are at least partly responsible for the distinct cellular properties between different cell types. Previous studies focusing largely on gene promoters and CpG islands have identified close association between several chromatin modifications and DNA methylation, but revealed a relatively small degree of differences between pluripotent and lineage-committed cells. more...

(Submitter supplied) The human embryonic stem cells (hESCs) are a unique model system for investigating the mechanisms of human development due to their ability to replicate indefinitely while retaining the capacity to differentiate into a host of functionally distinct cell types. In addition, these cells could be potentially used as therapeutic agents in regenerative medicine. Differentiation of hESCs involves selective activation or silencing of genes, a process controlled in part by the epigenetic state of the cell. more...

(Submitter supplied) Two-thirds of gene promoters in mammals are associated with regions of non-methylated DNA, called CpG islands (CGIs), which counteract the repressive effects of DNA methylation. In lower vertebrates, computational CGI predictions often reside away from gene promoters, suggesting a major divergence in gene promoter architecture across vertebrates. By experimentally identifying non-methylated DNA in the genomes of seven diverse vertebrates, we instead reveal that non-methylated islands (NMIs) of DNA are a central feature of vertebrate gene promoters. more...

(Submitter supplied) Epigenetic modification plays important roles in plant and animal development. DNA methylation can impact the transposable element (TE) silencing, gene imprinting and regulate gene expression.Through a genome-wide analysis, DNA methylation peaks were respectively characterized and mapped in maize embryo and endosperm genome. Distinct methylation level across maize embryo and endosperm was observed. The maize embryo genome contained more DNA methylation peaks than endosperm. However, the endosperm chloroplast genome contained more DNA methylation peaks to compare with the embryo chloroplast genome. DNA methylation regions were characterized and mapped in genome. More CG island (CGI) shore are methylated than CGI in maize suggested that DNA methylation level is not positively correlated with CpG density. The DNA methylation occurred more frequently in the promoter sequence and transcriptional termination region (TTR) than other regions of the genes. The result showed that 99% TEs we characterized are methylated in maize embryo, but some (34.8%) of them are not methylated in endosperm. Maize embryo and endosperm exhibit distinct pattern/level of methylation. The most differentially methylated two regions between embryo and endosperm are High CpG content promoters (HCPs) and high CpG content TTRs (HCTTRs). DNA methylation peaks distinction of mitochondria and chloroplast DNA were less than the nucleus DNA. Our results indicated that DNA methylation is associated with the gene silencing or gene activation in maize endosperm and embryo. Many genes involved in embryogenesis and seed development were found differentially methylated in embryo and endosperm. We found 17 endosperm-specific expressed imprinting genes were hypomethylated in endosperm and were hypermethylated in embryo. The expression of a maize DEMETER -like (DME-like) gene and MBD101 gene (MBD4 homolog) which direct bulk genome DNA demethylation were higher in endosperm than in embryo. These two genes may be associated with the distinct methylation level across maize embryo and endosperm.The methylomes of maize embryo and endosperm was obtained by MeDIP-seq method. The global mapping of maize embryo and endosperm methylation in this study broadened our knowledge of DNA methylation patterns in maize genome, and provided useful information for future studies on maize seed development and regulation of metabolic pathways in different seed tissues.
