m6A methylation of super-enhancer RNAs facilitates chromatin accessibility


Previous studies reported an effect of N6-methyladenosine (m6A) of super-enhancer RNAs (seRNAs) on chromatin accessibility and gene transcription. We investigated seRNA m6A levels in pancreatic ductal adenocarcinoma (PDAC) and found that aberrantly increased m6A methylation promoted local chromatin accessibility, resulting in increased transcription of oncogenes acting in PDAC progression.
