The probability of suffering from CRC is approximately 4–5%, and the risk of developing CRC is associated with characteristics such as age, chronic disease history, and lifestyle (2). CRC is caused by mutations in oncogenes, tumor-suppressor genes, and genes related to DNA repair mechanisms. The underlying pathogenic mechanisms are threefold; namely, chromosomal instability (CIN), microsatellite instability (MSI), and CpG island methylator phenotype (CIMP). In CRC, common mutations, chromosomal changes, and translocations reportedly affect important intracellular signaling pathways [WNT, mitogen activated protein kinase (MAPK)/phosphoinositide 3-kinase (PI3K), transforming growth factor (TGF)-β, and TP53] (2). In addition to genetic mutations, alterations in non-coding RNAs, such as microRNAs, also contribute to carcinogenesis. UR - https://tcr.amegroups.org/article/view/17512
