Following publication of the original article [1], the authors identified an error in Fig. 8. In the version of this article initially published, they found one panel in Fig. 8d was used by mistake. The authors want to update it to the correct one. The other elements of the figure remain the same, and the interpretation of the results remains unchanged. The authors’ subsequent studies on MIR22HG have confirmed that the results and conclusions in this study are correct and not affected by this erratum. The correct figure is given below.
