WebFeb 1, 2014 · CTCF plays numerous critical roles in chromatin organisation and regulation of gene expression. Abrogation of these normal functions due to mutation or deletion in cancer likely contributes to cancer-associated epigenetic changes and gene deregulation. The CTCF paralogue BORIS is frequently deregulated in cancer.
