Correction to: Cancer Gene Ther https://doi.org/10.1038/cgt.2014.29, published online 13 June 2014

Following the publication of this article, the authors noted that the panel in Figure 1b for AS-miR-221 had mistakenly been placed to show AS-miR-221/222. The correct panel for AS-miR-221/222 has now been included in the below revised figure. The conclusions of the article are unaffected by this correction.

The original article has been corrected.
