  1. ...suggest that bivalent domains are likely a product of PRC2 activity at genomic regions with high CpG density.H3K4me3 at bivalent chromatin protects promoters from de novo DNA methylationGene promoters targeted by PRC2 in ESCs—mostly bivalent genes—are often found to be DNA hypermethylated in adult human...
  2. ...examples of hypo- and hypermethylated DNA regions associated with specific chromatin signatures are displayed below.DNA hypomethylation during aging preferentially occurs at H3K4me1-rich sitesTo identify chromatin marks associated with CpG sites hypomethylated in aged MSCs, we aligned the DNA sequences...
  3. ...transcription start sites that are not within a CpG island. For disease, the generated DNA methylation fingerprints show that, during tumorigenesis, human cancer cells underwent a progressive gain of promoter CpG-island hypermethylation and a loss of CpG methylation in non-CpG-island promoters. Although...
  4. ...Age-associated DNA methylation in pediatric populations Reid S. Alisch 1 , 4 , Benjamin G. Barwick 1 , 4 , Pankaj Chopra 1 , Leila K. Myrick 1 , Glen A. Satten 1 , 2 , Karen N. Conneely 1 and Stephen T. Warren 1 , 3...
  5. ...signatures (Fisher’s exact test, P = 10#2;30) with >80% concordance. Healthy and pretreatment samples were thus combined and supervised analysis was performed on this larger set to identify with more confidence a DNA methylation signature for aging. This gave 589 age-associated CpGs (q < 0.05), termed...
  6. ...Neonatal DNA methylation profile in human twins is specified by a complex interplay between intrauterine environmental and genetic factors, subject to tissue-specific influence Lavinia Gordon 1 , Jihoon E. Joo 2 , 3 , Joseph E. Powell 4 , 5 , Miina...
  7. ...decline in tissue and organ function and is associated with many diseases, including cancer. At the genomic level, alterations to the epi contribute to the development of age-associated diseases (López-Otín et al. 2013; Booth and Brunet 2016). DNA methylation is a relatively stable component of the epi...
