  1. ...increase in late-replicating regions (Watanabe et al. 2002; Stamatoyannopoulos et al. 2009). It was proposed that the increase in mutation rates in non-CpG and CpG sites results from a single mechanism, namely, an increase of DNA damage during replication (Stamatoyannopoulos et al. 2009). However...
  2. ...methylation arrays, which provide the DNA methylation levels of CpG dinucleotides primarily in promoter and regulatory regions (Bibikova et al. 2011). We reduced the data based on overall variance using the 500 most variable probes for cluster analysis and performed unsupervised k-medoids-based clustering...
  3. ...editing deviated from SBS2 associated with DNA mutations and also varied between A3A and A3B (Fig. 2H,J). Briefly, (1) both A3A and A3B exhibited reduced specificity for the UpCpU context (TpCpT in DNA). However, (2) A3A displayed enhanced specificity for the UpCpG context (TpCpG in DNA), and (3) A3B...
  4. ...methylation varies in different organisms. In mammalian cells the pattern consists of long tracts of DNA in which CpGs are methylated to a high average level (∼80%) punctuated by short unmethylated regions called “CpG islands” ( Bird 1986 , 2002 ). CpG islands are GC-rich in base composition and have a CpG...
  5. ...Tables S1–S5). These numbers are comparable to those observed in human cells with a similar enrichment and sequencing approach (Serre et al. 2009). The identified DNA methylation peaks are enriched for CpG dinucleotides when compared to the average, whereas their GC content is only marginally higher than...
  6. ...-in control, we estimated the bisulfite conversion rate of Methyl-SNP-seq to be 97.5%. Overall CpG methylation is at 45.3% for both replicates in line with the two ENCODE data sets analyzed showing 45.5% and 50.1% overall CpG methylation, respectively. The GC bias of Methyl-SNP-seq follows closely the known...
  7. ...the variants also in the context of the 5′ and 3′ base adjacent to the variant shows that the main substitutions were strong-to-weak transitions in the context of CpG sites (VCG). Further, the comparison of our observed mutational signature with COSMIC indicates an overlap of ∼51% of the variants explained...
  8. .... ECs demonstrate a striking convergence of both CpG and CpH (non-CpG) methylation with pluripotent states; the pluripotential methyl-CpH signature crosses species boundaries and is distinct from neuronal methyl-CpH. EC differentiation to TE and YST entails reprogramming toward the somatic state...
  9. ...mechanisms causing gBGC in humans. It is known that the methylation of cytosines at CpG sites is responsible for their hypermutability: The spontaneous deamination of 5-methylcytosine causes the formation of G/T mismatches in DNA that, if not repaired, lead to G:C → A:T mutations in the next round of DNA...
  10. ...estimates of f in CpG compared with gBGC or NCB sites (Wilcoxon text, P < 10−16) (Supplemental Fig. S8) suggests that CpG hypermutability (Shen et al. 1992) is a potent source of deleterious nonsynonymous mutations. Consistent with this hypothesis, nonsynonymous SNVs in CpG sites have significantly higher...
