Project description:Genome wide DNA methylation profiling of peripheral blood mononuclear cells(PBMCs) in normal and CRC samples. The Illumina Infinium 850k Human DNA methylation Beadchip was used to obtain DNA methylation profiles across approximately 820,000 CpGs in PBMC samples. Samples included 50 newly diagnosed CRC patients and 50 normal controls. NOTE:Patients numbered "CRC" and "E-CRC" are from two wards of the same hospital and do not need to be treated differently in data analysis.
