The Editors-in-Chief have retracted this article. Concerns with Fig. 6B were previously addressed with a correction  but more image irregularities have been identified, specifically:
Figure 2D: theShp(KO) + CS panel appears to partially overlap with the MK-2206 + CS MMP-9 panel of Fig. 2C in a previously published article .
Figure 5A: there appears to be a splice in the Pro-MMP-9 band.
Figure 7A: the JNK 1.25 and 2.5 blots appear to be identical to the JNK //- and +// blots in Fig. 7B.
The Editors-in-Chief therefore no longer have confidence in the results reported in this article.
Authors Ya-nan Liu Jian Shen, Jian-cang Zhou, Hui-juan Shen, Qiang Shu, Qiang-min Xie and Yicheng Xie agree with this retraction. The other authors have not responded to correspondence regarding this retraction.
