Retraction Note: MicroRNA-302b suppresses cell proliferation by targeting EGFR in human hepatocellular carcinoma SMMC-7721 cells (BMC Cancer, (2013), 13, 1, (448), 10.1186/1471-2407-13-448)

The Editors have retracted this article because concerns were raised about image overlap with another article published by some of the same authors shortly after the publication of this article. Further investigation by the publisher found mismatches between the raw images the authors provided and the published images. Additionally, this study involves experiments with contaminated cell lines, SMMC-7721 and HL-7702, which were not known at the time of the study. The Editors therefore no longer have confidence in the data presented in this article. Author, Lumin Wang disagrees with this retraction. Authors, Jiayi Yao, Xin Shi, Lili Hu, Zongfang Li, Tusheng Song, and Chen Huang have not responded to any correspondence from the editor/publisher about this retraction.
