In particular, the expression levels of MMP1, MMP3, MMP7, MMP9, MMP10, MMP11, MMP12, MMP13, and MMP14 were significantly upregulated in CRC tumor tissues compared to normal tissues, while MMP15, MMP17, MMP25, MMP27, and MMP28 were significantly downregulated. This evidence concerns the gene MMP11 and colorectal carcinoma.
