  1. ...for this article.] In mammalian DNA, cytosines within CpG dinucleotides are heavily methylated throughout the , yet there are several discrete “islands” that contain a high frequency of unmethylated CpG sites. These are called CpG islands (CGI), and their identification has long been considered important...
  2. ...coefficient) with both methods (Supplemental Fig. S1C,D). Further analyses demonstrate that GPS has higher efficiency when detecting DNA methylation in the repetitive elements, CpG islands, and GC-rich region such as promoter regions (Fig. 1D–F; Supplemental Fig. S2). Moreover, the methylation sites detected...
  3. ...binding, DNA methylation, and gene expression in DKO ESCs and developed biophysical models to predict differential CTCF binding. Methylation-sensitive nucleosome repositioning accounted for a significant portion of CTCF binding loss in DKO ESCs, whereas unmethylated and nucleosome-depleted CpG islands...
  4. ..., intragenic methylation has been linked to transcriptional and splicing activities ( Jones 2012), suggesting a sophisticated regulatory potential for this epigenetic modification. DNA methylation levels are closely related to the genomic context, with CpG-rich regions (CpG islands) located in the 59 endof...
  5. ...Table S4). These methylation differences associated with cell culture occur predominately as unmethylated CpGs in the bodies of genes involved in regulating cellular proliferation (GO:0042127, P = 5.17 3 10#2;4). Studies of DNA methylation that use cell lines as model systems could use this list...
  6. ...reveals substantial inter-individual variation in DNA methylation. Classification of the 186 regions into CpG islands, 59 regions, conserved noncoding, and 1814 Genome Research www..org Gervin et al . lic lic Genome Research 1815 www..org Variation and heritability of DNA methylation lit Gervin et al...
  7. ...in DNA methylation during erythroid development. Analysis of genomic features revealed that 98% of promoter CpG islands are hypomethylated, while 20%–25% of non-promoter CpG islands are methylated. Proximal promoter sequences of expressed genes are hypomethylated in all cell types, while gene body...
  8. ...statistical framework which we call ‘‘M&M’’ (for integration of MeDIP-seq and MRE-seq) that detects DMRs. M&M explicitly models the relationship between DNA methylation level, CpG content, and expected MeDIP and MRE reads in any given genomic context. By analyzing WGBS, MeDIPseq, and MRE-seq data for the same...
  9. ...neglected in previous studies. Our findings in CD4+ T cells are in line with a recent study in ES cells that also identified promoterdistal regions as the main sites of dynamic changes in DNA methylation upon differentiation (Meissner et al. 2008), andwith a study on tissue-specific CpG island methylation...
  10. ..., and that hypomethylation largely occurs outside of CpG islands. (B) Volcano plot of the differential DNA methylation analysis. (X-axis) Median b-value difference (median tumor-median NTL); (y-axis) Q-values for each probe (#2;1 3 log10 scale). (Vertical dotted lines) 20% change in b-values; (horizontal dotted line...
