  1. ...and stochastic accumulation of epigenetic changes, such as DNA methylation variability, with advancing age. Although increasingly recognized for its potential role in aging biology, its extent, biological significance, and population specificity remain insufficiently characterized. Here, we present the first...
  2. ...Pluripotent stem cells escape from senescence-associated DNA methylation changes Carmen M. Koch 1 , Kristina Reck 1 , Kaifeng Shao 2 , Qiong Lin 3 , Sylvia Joussen 1 , Patrick Ziegler 4 , Gudrun Walenda 1 , Wolf...
  3. ...with an intermediate level of resolution of CpGs at the genomic level. We obtained a DNA methylation fingerprint of 1628 human samples in which we interrogated 1505 CpG sites. The DNA methylation patterns revealed show this epigenetic mark to be critical in tissue-type definition and stemness, particularly around...
  4. ...in the other samples (Supplemental Table S1, column 7), we speculate that they are genomic instability “hotspots,” where mutation is frequent in DNA repair compromised cells.Human pluripotent stem cells have a different methylation statusNext, we analyzed rDNA methylation status in human induced pluripotent...
  5. ...is that the differences in the number of individuals analyzed and different data analyses undertaken make the interpretation of the comparison of age-dependent DNA methylation changes in different cell types difficult. However, the conserved pattern of chromatin signatures in stem and differentiated cells suggests that H...
  6. ...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...
  7. ...of resting PBMCs.View larger version: In this window In a new window Figure 4. mtDNA in T cells shows stimulation- and age-dependent changes. (A) T cells from 22 healthy donors (aged 33 ± 7) were stimulated at day 0 by anti-CD3/CD28 beads and mtDNA per cell equivalent was measured over a 15-d period...
  8. ...of their chromatin status in ESCs, we provide evidence that DNA hypermethylation preferentially targets the subset of PcG genes that are developmental regulators, and this may contribute to the stem-like state of cancer. Additionally, the capacity for global methylation profiling to cluster tumors by phenotype may...
  9. ...reads of DNA isolated from ancient remains. Using the genome sequence data generated from hair shafts of a 4000-yr-old Paleo-Eskimo belonging to the Saqqaq culture, we generate the first ancient nucleosome map coupled with a genome-wide survey of cytosine methylation levels. The validity of both...
  10. ...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...
