Human derived and patient derived xenografts epigenome analysis of primary and metastasis colorectal cancer

Genome wide DNA methylation profiling of primary (PR) and liver metastasis (LM) colorectal cancer (CRC). The Illumina Infinium MethylationEPIC Beadchip was used to obtain DNA methylation profiles across approximately 850,000 CpGs in human and xenogratfs derived samples. Raw data were processed using R minfi package. The main goal of this study is to develop a methylation-based classifier and predictor for metastatic CRC (mCRC), in order to find specific patients stratification for anti-EGFR targeted therapy (cetuximab) and bring the promise to shed new light on the role of methylation in driving colorectal cancer progression in different groups of patients.
