We have recently noticed an accidental error in part of a figure which appeared in the above-mentioned article. In Fig. 3A, the image for the HGC27-pEF, 15 h panel was mistakenly replicated as the HGC27-KD, 0 h panel in the same figure, and the AGS-pEF, 15 h and AGS KD, 0 h panels were mistakenly switched with each other.
We have reviewed the original files and the individual figures for the submitted composite figure, and realized that the error occurred when we produced the composite figure by marrying the individual images to the final figure. The same image was accidentally pasted twice without us being fully aware of the error. We have identified all the original images, and the corrected version of Fig. 3 is shown on the right.
We regret that this error occurred, and thank the Editor for affording us the opportunity to publish this Corrigendum.
(A) Wound-healing assay was used to assess the effect of SGPP1 knockdown on the migration ability of the gastric cancer cells. HGC27 cells (top panel) and AGS cells (bottom panel). (B) The influence of SGPP1 knockdown on the invasive ability of HGC27/AGS cells. HGC27 cells (left panel) and AGS cells (right panel). Data shown are the mean value of three experiments in triplicate. Experiments were repeated at least three times. Data are presented as the mean ± SEM; *P<0.05. SGPP1, sphingosine-1-phosphate phosphatase 1.
