The Editors-in-Chief have retracted this article. After publication, concerns were raised regarding high similarity between the images presented in this article and a number of other articles on non-coding RNAs [1–5]. The Editors-in-Chief therefore no longer have confidence in the presented data.

The authors have not responded to any correspondence from the editor or publisher about this retraction.
