Colorectal cancer (CRC) is one of the most frequent cancers leading to death worldwide. Different signaling pathways such as the canonical Wnt signaling pathway have many effects on the development of CRC. MicroRNAs are small non-coding RNAs and different evidence represent their importance in the development of cancer via regulating the expression of their target genes. miRNAs can affect CRC progression as oncogenes or tumor suppressors. Dysregulation in miRNA expression can occur for various reasons, causes different abnormalities in the Wnt signaling pathway, and contributes to CRC development. Identifying the exact interactions between microRNAs and mRNAs or other non-coding RNAs assists in designing effective therapeutic, diagnostic, and prognostic approaches. In this review, we aim to focus on microRNAs that regulate CRC through modulating the Wnt pathway and then present the perspective outlook on the implication of miRNA in liquid biopsy for the management of patients with CRC.

D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D012333 RNA, Messenger RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

D015179 Colorectal Neoplasms Tumors or cancer of the COLON or the RECTUM or both.

D060449 Wnt Signaling Pathway A complex signaling pathway whose name is derived from the DROSOPHILA Wg gene, and the vertebrate INT gene. The signaling pathway is initiated by the binding of WNT PROTEINS to cell surface WNT RECEPTORS which interact with the AXIN SIGNALING COMPLEX and an array of second messengers that influence the actions of BETA CATENIN.

D035683 MicroRNAs Small double-stranded, non-protein coding RNAs, 21-25 nucleotides in length generated from single-stranded microRNA gene transcripts by the same RIBONUCLEASE III, Dicer, that produces small interfering RNAs (RNA, SMALL INTERFERING). They become part of the RNA-INDUCED SILENCING COMPLEX and repress the translation (TRANSLATION, GENETIC) of target RNA by binding to homologous 3'UTR region as an imperfect match. The small temporal RNAs (stRNAs), let-7 and lin-4, from C. elegans, are the first 2 miRNAs discovered, and are from a class of miRNAs involved in developmental timing.
