CDH1 and cancer: In cancer cells, miR-320 has a tumor-suppressor function; it is downregulated in different cancers such as breast cancer, glioma, gastric cancer, retinoblastoma, and human non-small-cell lung cancer, and it represents an important EMT inhibitor by reducing the levels of E-Cadherin and increasing those of N-Cadherin and Vimentin [31,72,75,76,77,78].
