WNT-mediated gene gating: a novel principle connecting oncogenic super-enhancers with the nuclear pore to drive pathological expression of MYC.

ABSTRACT

WNT signaling enhances MYC expression in cancer cells to increase the rate of cell proliferation. We have recently found that this principle involves the gating of MYC to nuclear pores mediated by an oncogenic super-enhancer in a ß-catenin-dependent manner in colon cancer cells. This phenomenon, which is absent in normal cells, leads to pathological levels of MYC expression.
