Aberrant expression of miRNAs has been reported for most types of cancers, including CRC [55], and in particular miRNAs regulate critical pathways involved in the CRC pathogenesis such as the p53, PI3K, RAS, MAPK, EMT transcription factors, and Wnt/β-catenin pathways [56]. This evidence concerns the gene TP53 and colorectal carcinoma.
