A teаm studying cоlоrectаl cаncer nоtices that CTCF binding at a specific locus is lost in 70% of tumor samples, despite no mutation in the CTCF gene itself. Bisulfite sequencing reveals CpG hypermethylation within the CTCF consensus binding motif at that locus. The region normally serves as a boundary separating the oncogene MYC from a strong enhancer cluster active in intestinal stem cells. What is the most likely mechanism by which this epigenetic change promotes tumorigenesis?
