We found a significant increasing trend of cell migration ability in CLDN18-ARHGAP26 overexpressed gastric cancer cells, but no significant changes in cell growth, probably due to different selections of cell lines from Yao’s reports (e.g., they used breast cell line MCF10A to illustrate the reduced cell proliferation, while we used multiple gastric cancer cell lines). Here, CLDN18 is linked to gastric cancer.
