The definition ofDNA methylationis binding of a methyl group (CH3) to the carbon 5 of cytosine at CpG sites of DNA sequence by the covalent bond via an enzymatic reaction that produces 5-methylcytosine (5-mc) and rises to the gene suppression. Near to the promoter region of almost 30% ...

3.3. DNA methylation-based definition of breast cancer subtypes Given the distinctive epigenomic features observed in association with LumB and Basal-like breast cancers, i.e. CpG island promoter methylation and gene body hypomethylation in LumB and Basal-like tumors, respectively, we set out to det...
related disease pathology, including the construction of chronological and biological age predictors (termed DNA methylation ‘clocks’). Three studies investigate the substantial stochastic contribution to these epigenetic changes and further our understanding of aging biology, as well as of these ...
Through a genome-wide analysis of DNA methylation across 19 cell types with T-47D as reference, we identified 106,252 cell type-specific differentially-methylated CpGs categorized into 7,537 differentially (46.6% hyper- and 53.4% hypo-) methylated regions. We found 44% promoter regions and 75%...

133, 134, 135, 136, 137 The identification of cell of origin is essential to stem cell biology and cancer research. As an epigenetic memory of cell origin, DNA methylation profiles will be useful in the development of regenerative medicine and tumor-type-specific and patient type-specific ...
(Extended Data Fig.4). This high similarity in DNA methylation across donors is on a par with the estimated interindividual variability of genomic sequence22. Whereas the definition of 50% is somewhat arbitrary, other thresholds (35–50%) show a similar trend, with 0.5% or less variable ...
