Our analysis revealed that genes that encode molecules that are commonly up-regulated during EMT such as FOXC2, SNAI1, SNAI2, TWIST1, ZEB1, FN1, WNT5A, MMP2, MMP9, SERPINE1, and ITGA5 generally exhibit a negative correlation with the co-expression of PEBP1/STK11 across most cancer types, with a few exceptions (Figure 8). This evidence concerns the gene MMP2 and cancer.
