TGFB1 and gastric cancer: The same genomic profile was observed in GC patients in the TCGA dataset (n = 408), in which BGN was inversely correlated with epithelial markers (CDH1: Spearman R = −0.38, p value < 0.001; CKR19: Spearman R = −0.27, p value < 0.001) and directly correlated with the mesenchymal gene signature (VIM, SNAI1, SNAI2, TGFB1, MMP2, MMP14, CDH2, ZEB1, ZEB2, and FN1: Spearman R > 0.5, p value < 0.001) (Figure 4F).
