Retraction Note: Upregulation of the long non-coding RNA AFAP1-AS1 affects the proliferation, invasion and survival of tongue squamous cell carcinoma via the Wnt/β-catenin signaling pathway.

The authors have retracted this article [1] because there are errors in Figures 4a and 4b.

The authors have retracted this article [1] because there are errors in Figures 4a and 4b. In these figures a number of cell field views are replicated between experimental groups:

In Figure 4b the Scc-9/Mock panel replicates the Scc-9/shR-NC panel in Figure 4a

In Figure 4b the CAL-27/Mock panel replicates the CAL-27/Mock panel in Figure 4a

In Figure 4b the CAL-27/sHR-Nc panel replicates the CAL-27/sHR-Nc panel in Figure 4a

In Figure 4b the CAL-27/shR-AFAP1-AS1 panel replicates the CAL-27/shR-AFAP1-AS1 panel in Figure 4a

The conclusions of this study are therefore not reliable. Zhaojian Gong, Hanjiang Wu, Shanshan Zhang, and Shuai Zhang agree with this retraction. Ze-you Wang, Min Hu, Min-hui Dai, and Jing Xiong agree with the retraction but did not respond to further correspondence about the retraction notice.
