M6A modification of circNSUN2 promotes colorectal liver metastasis

Publication date: Available online 20 December 2019Source: Genes & DiseasesAuthor(s): Rong-Zhang He, Jing Jiang, Di-Xian LuoAbstractCircular RNAs (circRNAs) are playing emerging role in the pathogenesis of cancers, but the mechanisms still unknown. In the recent issue of the Nature Communications, Chen and colleagues demonstrated that YTHDC1 facilitates N6-methyladenosine modification of circNSUN2 cytoplasmic export and the circNSUN2/IGF2BP2/HMGA2 complex stabilizes HMGA2 to promote colorectal liver metastasis. These discoveries not only expand our understanding of circRNAs biology in tumor, but also demonstrate that m6A modification plays a key role for circRNAs in RNA metabolism. Therefore, these findings indicate that circRNAs may be a new approach for therapeutic target of cancers.
