  1. ...megakaryopoiesis as a transcriptional repressor at loci defined by a specific DNA signature. Our findings reveal important new insights into how ERY and MEG lineages arise from a common bipotential progenitor via overlapping and divergent functions of shared hematopoietic transcription factors. Footnotes...
  2. ...A heterozygous IDH1 R132H/WT mutation induces genome-wide alterations in DNA methylation Christopher G. Duncan 1 , 6 , Benjamin G. Barwick 2 , 6 , Genglin Jin 1 , Carlo Rago 3 , Priya Kapoor-Vazirani 4 , Doris R. Powell 4...
  3. ...of the polymerase and perhaps dephosphorylation prior to release. Lysine 36 trimethylation occurs across transcribed genes, sometimes alternating with stretches of DNA in which lysine 36 dimethylation is more prominent. Lysine 36 methylation decreases at or near the site of polyadenylation, sometimes disappearing...
  4. ...constraint on the methylation state. Together, these data show that intergenic loci, specifically putative enhancers, with methylation states that dynamically change during differentiation are also the most likely to vary both between individuals and between species. Discussion Patterns of DNA methylation...
  5. ...) There are no other polymorphic genomic Figure 7. Differential methylation at ERVSlc15a2 reflects its parent of origin. DNAmethylation at left (L) 59 and right (R) 39 LTRs of ERVSlc15a2was assessed using bisulfite sequencing of genomic DNA purified from brains of indicated mouse lineages. (Top, schematic) In amplicon...
  6. .... At the DNA level, cytosine methylation (meC) is enriched for nucleosomes that remain at the TSS, whereas in general there is a dearth of meC at TSSs. Furthermore, a drop in meC also marks 3′ transcription termination, and a peak of meC occurs at stop codons. This mimics the 3′ nucleosomal distribution...
  7. ...they function as information-processing units by integrating the inputs of their respective upstream regulators into tightly controlled spatiotemporal expression patterns. Repetitive DNA, largely derived from transposable elements, is known to make up ∼50% of the human ( Lander et al. 2001 ) and has...
  8. ...community, deserving of the same level of scrutiny applied to other genic or regulatory features. Leaving the flat behind Gene regulation is fundamentally a three-dimensional (3D) process involving dynamic interactions between genomic DNA and the nuclear protein machinery. And yet, common conceptions...

  9. ...surrounded by genomic DNA (Kornberg and Lorch 1999). The flexible amino termini of nucleosomal histones harbor multiple residues that can be subjected to different types of reversible post-translational modifications, including acetylation and methylation (Bernstein et al. 2007; Li et al. 2007; Mellor et al...
