Correction to: Acta Pharmacologica Sinica https://doi.org/10.1038/aps.2016.113, published online 05 December 2016.

After publication, the authors realized that the representative images of DIR group in Fig. 4a were found to be misplaced due to the mishandling in the manuscript preparation. All the authors agree on the correction of our negligence as providing the corrected Fig. 4a presented below. This correction does not affect the results and conclusion of the paper. We sincerely apologize for our mistakes and any inconvenience this might have caused.
