CDH1 and neoplasm: For example, there are high expressions of lncRNA-HOTAIR, lncRNA-NORAD, lncRNA-linc00673, lncRNA-SLC26A4-AS1, lncRNA-ROR, lncRNA-PVT1, lncRNA-HOTAIR and other lncRNAs in thyroid cancer patients, which are positively correlated with tumor malignant phenotype and lymph node metastasis, while lncRNAs knockout in thyroid cancer cells can up-regulate the expression of E-cadherin protein and inhibit the occurrence of EMT [19, 136–140].
