ZEB1 and colorectal cancer: For example, Chen et al. reported that the lncRNA UICLM could function as a competing endogenous RNA (ceRNA) for miR-215 in colorectal cancer cells to regulate the expression of ZEB1 (32), and Li et al. demonstrated that lncRNA ZFAS1 functions as an oncogene in hepatocellular carcinoma progression by binding to miR-150 and abrogating its tumor-suppressive function (33).
