  1. ...-DhMRs or undergoing activation for up-DhMRs (Sérandour et al. 2012). In order to obtain a more complete view of these dynamic processes at the full sets of up- and down-DhMRs, we first analyzed the temporal variations of H3K4me1 and H3K27ac histone modifications -wide by ChIP-seq, together with those of 5hmC and 5m...
  2. ...DNA methylation, histone modifications, and positioning of nucleosomes over introns and exons and at exon/intron boundaries contribute significantly to the recognition of the core splicing signals and can change splice site selection, resulting in AS events (Braunschweig et al. 2013; Reddy et al. 2013...
  3. ...remain poorly characterized. At the core of chromatin are the histone proteins, which assemble DNA into nucleosomes, providing the basis for higher order chromatin packaging. A variety of post-translational histone modifications are used in combination to define alternative chromatin states (Jenuwein...
  4. ...cell types. Second, chromatin exists in several “states” (Barski et al. 2007; Heintzman et al. 2007; Ernst and Kellis 2010; Ernst et al. 2011; Hoffman et al. 2013) with a spectrum of functional properties that may be identified using ChIP-seq of histone modifications. In particular, transcription...
  5. ...that participates in erythroid differentiation, at least in part by complexing with GATA1 (Shivdasani et al. 1995); this latter feature is associated with positive regulation of target genes (Tripic et al. 2009). Furthermore, given the important role of histone modifications in gene regulation and the established...
  6. ...with the transcriptional start sites (TSSs) of genes, while H3K4me1 and H4ac have more widespread distributions. TSSs reveal characteristic patterns of both types of modification present and the position relative to TSSs. These patterns differ between active and inactive genes and in particular the state of H3K4me3 and H3...
  7. ..., a particular gene of interest (GOI) remains a persistent experimental and conceptual challenge. This gene-centric question is complicated by the multilayered regulatory environment in which each gene resides, comprising 3D chromatin structure, enhancer–promoter looping, DNA accessibility, histone modifications...

  8. ...nucleosome positioning elements. These results suggest that other factors appear to cooperate with the DNA sequence of these regions to impart nucleosome phasing. This study provides the first information on the chromatin structure of breakpoint regions in a common fragile site. The observation of phased...
  9. ...by modENCODE are shown in Supplemental Figure S4. Both H3K9acS10ph and H3K27acS28ph have very similar profiles as H3K4me3, suggesting these histone modifications occur on the same nucleosomes, the peak of which is located at the first nucleosome downstream from the TSS (Fig. 6A). These results suggest...
  10. ...is available for this article.] Modulation of the biochemical properties of nucleosomes through histone covalent modifications plays a crucial role in the regulation of transcription in mammals (Kouzarides 2007; Ruthenburg et al. 2007). These modifications can alter the structure of chromatin and stimulate...
