Super-enhancers: The villain fueling certain cancers

Researchers identified a small RNA molecule called miR-766-5p that reduces expression of MYC, a critical cancer-promoting gene. This microRNA reduces levels of proteins CBP and BRD4, which are both involved in super-enhancer (SE) formation. SEs form in areas of DNA that can fuel MYC expression and tumor progression. This study provides strong evidence for developing miR-766-5p as a novel therapeutic to treat MYC-driven cancers.
