TUG1 and colorectal carcinoma: LncRNA-ATB strengthens the inhibition on β-catenin degradation in the cytoplasm of non-small cell lung cancer cells through the miR-200a/β-Catenin axis to induce EMT conversion [26], which suggests that the lncRNA TUG1/miR-138-5p/ZEB2 axis inhibits CRC, but the specific influence of the lncRNA TUG1/miR-138-5p/ZEB2 axis on the EMT of CRC is still under investigation.
