RESUMO
This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). This article has been retracted at the request of the editor after publication concerns were raised with respect to data presented in Figure 2. The journal contacted Southern Medical University, Guangzhou, Guangdong Province, China, who formed an Academic Committee to investigate. According to the "Academic Ethics and Implementation Rules" of Southern Medical University, the Committee reported evidence of improper preservation of original data and incorrect use of pictures, and recommended immediate withdrawal of the paper. Specifically, in the PC-3 group of Fig. 2H, the 'Control' cell migration image had been partially duplicated in the 'Empty vector' image. As per journal policy, original files used to create the entire figure were requested. Raw western blot images were not available for Figure 2 C+F, and experimental repeats yielded protein level discrepancies with the original published data. The editors therefore no longer have confidence in the integrity of these data.
