Abstract 3305: Cell-of-origin differentiation stages define methylation-based subtypes of human colorectal adenomas and carcinomas

Introduction: Colorectal adenomas are precursor lesions of colorectal cancers and represent clonal amplifications of single cells from colonic crypts. DNA methylation patterns specify cell-type identity during cellular differentiation and therefore provide novel opportunities for tumor subclassification and patient stratification. Methods: Infinium 450k and EPIC data from of non-malignant colorectal adenomas was applied to a consensus clustering...
