Genome-scale analysis of aberrant DNA methylation in colorectal cancer

(Submitter supplied) To characterize DNA methylation-based subgroups in colorectal cancer, we performed genome-scale DNA methylation profiling of 125 colorectal tumor samples and 29 histologically normal-adjacent colonic tissue samples using the Illumina Infinium DNA methylation assay, which assesses the DNA methylation status of 27,578 CpG sites located at the promoter regions of 14,495 protein-coding genes. We identified four DNA methylation-based subgroups of CRC using model-based cluster analyses. more...

Illumina HumanMethylation27 BeadChip (HumanMethylation27_270596_v.1.2)

(Submitter supplied) HumanMethylation27 DNA Analysis BeadChip allows researchers to interrogate 27,578 highly informative CpG sites per sample at single-nucleotide resolution. This 12-sample BeadChip features content derived from the well-annotated NCBI CCDS database (Genome Build 36) and is supplemented with more than 1,000 cancer-related genes described in published literature. Probe content has been enriched to deeply cover more than 150 well-established cancer genes known to show differential methylation patterns. more...
