Retraction of: Scientific Reports https://doi.org/10.1038/srep26679, published online 27 May 2016

The Editors have retracted this Article.

After the publication of this Article it was brought to the Editors' attention that it shows multiple instances of overlap of data between various figures, where the data are described as corresponding to different samples or conditions. Additionally, non-inclusive overlaps with differently described data were identified in subsequently published work1. The Authors were contacted and asked for an explanation and for the raw data but have not responded. The Editors therefore no longer have confidence in the data reported in this Article.

Biao Deng, Lei Qu, Jiaqing Fang, Shouwen Yang, Zhongwei Cao, Zhechuan Mei & Xing Sun did not respond to the correspondence about the retraction. The Editors were not able to establish the current contact details for Jinfang Li.
