Correction to: Cell Research https://doi.org/10.1038/cr.2016.6, published online 15 January 2016

In the main figure, Fig. 1a has been replaced by an updated figure as follows.

It was noticed recently that in the original version of the paper, Fig. 1a included an image that shared some similarities with a figure panel of Fig. 2b from our prior publication (PMID: 24582927). To ensure the integrity of the data and reflect results from independent experiments, we have replaced Fig. 1a with updated panels derived from independent samples.

The authors confirm that this correction does not affect the results or the conclusion of this work.
