DNMT3A and colorectal carcinoma: Likewise, in colorectal cancer (CRC), including IBD‐associated CRC, the enzymes DNMT3A and DNMT1 evidenced as targets of mir-143 and miR-342, respectively, have shown increased expression levels, correlating with low levels of miR-143 and miR-342 and thereby with tumor growth and cell proliferation [53, 54].
