Zhang Z, Tan X, Luo J, Cui B, Lei S, Si Z, Shen L, Yao H. GNA13 promotes tumor growth and angiogenesis by upregulating CXC chemokines via the NF-κB signaling pathway in colorectal cancer cells. Cancer Med. 2018;7(11):5611-5620. https://onlinelibrary.wiley.com/doi/full/10.1002/cam4.1783. The above article, published online on September 28, 2018, in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors, the journal's Editor-in-Chief, Dr Stephen Tait, and John Wiley & Sons Ltd. The retraction has been agreed due to evidence of image duplication between figures 3D, 3E, and 6C and figures from articles published elsewhere in a different scientific context. As a result, the journal no longer has confidence in the results and conclusions.
