  1. ...nucleosome map and methylation levels were confirmed by the recovery of the expected signals at promoter regions, exon/intron boundaries, and CTCF sites. The top-scoring nucleosome calls revealed distinct DNA positioning biases, attesting to nucleotide-level accuracy. The ancient methylation levels exhibited...
  2. ...adaptations to Y Chromosome degeneration can arise de novo, as the sex chromosomes of model systems are ancient, making it difficult to extrapolate the initial stages in the evolution of dosage compensation and obscuring cause from consequence.A classic model of sex chromosome degeneration proposes loss...
  3. ...a significantly stronger influence on gene expression correlation than older 25 TF motif enhancers found near ruminant ancestral EBRs, containing significantly fewer TFBSs for the 25 TFs. This implies that an introduction of novel TFBSs in evolution might affect gene expression -wide, but genes in/near lineage...
  4. ...expressed retrocopies show lower expression than protein-coding genes (Fig. 1C; Supplemental Fig. S3; Supplemental Data), while transcriptional profiles of platypus and chicken retrocopies are similar to those of protein-coding genes (Fig. 1C; Supplemental Fig. S3), likely due to their more ancient origin...
  5. ...al. 2003 ) rather than ancestral to prototherians (sensu Luo et al. 2002 ). Considering the disputed and dubious phylogenetic position of A. mahabo , it seems prudent to abide by the older dates for the earliest mammalian divergences (see main text), which are supported by considerable molecular...
  6. ...of portions of ancient SINE insertions both in noncoding and coding regions of the ( Bejerano et al. 2006 ; Kamal et al. 2006 ; Nishihara et al. 2006 ). In one notable instance, a B2 SINE element was found to serve as a boundary element for transcriptional regulation during organogenesis ( Lunyak et al. 2007...
