Retraction: "MicroRNA-103 confers the resistance to long-treatment of adriamycin to human leukemia cells by regulation of COP1," by Lin Wan, Yanlong Tian, Rui Zhang, Zhuo Peng, Jiangli Sun, and Wanggang Zhang, J Cell Biochem. 2018; 3843-3852: The above article, published online on 23 Oct 2017 in Wiley Online Library (https://onlinelibrary.wiley.com/doi/full/10.1002/jcb.26431), has been retracted by agreement between the journal's Editor in Chief, Prof. Dr. Christian Behl, and Wiley Periodicals LLC. The authors asked to retract this manuscript as their confidence in the results has been undermined by possible contamination of K562 and KASUMI-1 cell lines. The retraction has been agreed following an investigation based on allegations raised by a third party. Raw data was provided and multiple inappropriate modifications especially in the backgrounds of blots were revealed by an image integrity check. The authors collaborated in the investigation initially, but were not available for a final confirmation of the retraction.
