CTCF and colorectal cancer: Long noncoding RNA Colorectal Cancer Associated Transcript 1-long (CCAT1-L) reportedly interacts with CTCF in the MYC locus and regulates chromatin conformation in colorectal cancer cells [86], and recently, a study demonstrated that hnRNPK interacted with CCAT1-5L RNA and regulated the formation of a super-enhancer complex, using RNA in situ conformation sequencing (RIC-seq) [72].
