Elevated expression of miR-135, which targets the APC mRNA, has been observed in colorectal adenomas and adenocarcinomas with/without biallelic APC mutations, suggesting that this miRNA could play a primary or synergistic role in activation of the canonical WNT signaling pathway during colon cancer development (Nagel et al., 2008). The gene discussed is APC; the disease is malignant colon neoplasm.
