The expression of two other transcription factors, ELF3 and KLF5, also correlated with the expression of CDX2 in gastric cancer (Spearman correlation coefficient 0.21, p = 1.07 × 10−5, and Spearman correlation coefficient 5.49, p = 1.07 × 10−13, respectively, Figure 4C and Figure 4D). Here, CDX2 is linked to gastric cancer.
