Some circular RNA molecules serve as molecular “sponges,” binding to and deactivating gene modulators called microRNAs to influence gene expression, according to two papers published this week (February 27) in Nature. The findings reveal a hidden world of previously unexplored RNA molecules, and act as a reminder that there is more to RNA than simply being a messenger between DNA and the proteins it encodes. - See more at: http://www.the-scientist.com//?articles.view/articleNo/34544/title/Circular-RNA-Surprise/#sthash.7Q7htOh8.dpuf
