By analyzing the cancer genome atlas (TCGA) data, we found that FOXS1 expression was significantly higher in gastric cancer samples than in noncancerous samples (normal = 38, cancer = 371, P < 0.001), consistent with the finding that FOXS1 expression was higher in in gastric cancer tissue than in normal gastric tissue in GSE19826 (N = 15, C = 12, P < 0.001), GSE13911 (N = 31, C = 38, P < 0.001) and GSE51575 (N = 26, C = 26, P < 0.001) datasets (Table 1). This evidence concerns the gene FOXS1 and gastric cancer.
