TP53 and colorectal carcinoma: Further insights into the pathogenesis of CRC can be gained by understanding the role of lncRNAs in tumorigenic signaling pathways like Wnt/ β-catenin, EGFR/IGF-1R, KRAS, phosphatidylinositol-3-kinase (PI3K), transforming growth factor-beta (TGF-), p53, and EMT signaling pathways [64].
