WebFor example, tumor-derived CTCF mutants lost the binding affinity to growth-regulatory genes such as Myc, ARF and Igf2 (insulin-like growth factor 2) [168]. Deregulation of these genes may contribute to malignant tumor phenotypes. It is proposed that CTCF integrity may be important in controlling tumor angiogenesis [169,170]. Zinc-finger ... WebAug 1, 2014 · In addition, it was shown that CTCF activates PARP1, resulting in DNA hypomethylation, which has been linked to cancer initiation and progression. Interestingly, comparison of existing datasets of genome-wide CTCF and PARP1 residence on chromatin revealed that sites of overlap (deemed “hot spots”) are both intergenic as well as …
