DUSP4 and breast carcinoma: This prediction was partly based on evidence of long-range regulatory chromatin interactions between CCVs and the DUSP4, promoter which included RNA polymerase II chromatin interaction analysis by paired-end tag sequencing (ChIA-PET) data in a breast cancer cell line [6], Hi-C chromatin-interaction and bioinformatic analysis identifying an enhancer coincident with CCVs that interacts with the DUSP4 promoter [7], and capture Hi-C data from breast cancer cell lines [8].
