Author Correction: Co-delivery of docetaxel and silibinin using pH-sensitive micelles improves therapy of metastatic breast cancer

Correction to: Acta Pharmacol Sin https://doi.org/10.1038/aps.2017.74, published online 17 July 2017

The authors apologize that due to our neglect, in the initially published version of this article, wrong images were pasted for the C6 group when doing the pictures layout of Fig. 3. Because the related text in the paper stated that “The free C6 exhibits a dim green fluorescence, while CM displays a stronger fluorescence intensity” (page 1658, the left column, lines 8–17), and both the correct and the wrong images of the C6 group showed very weak fluorescent intensity of coumarin-6, the arguments and conclusions of the original article are not affected. We apologize again for any inconvenience caused.

The correct Fig. 3 is as follow:
