The expression of E-cadherin had a positive correlation with the expression of miR-631, while expressions of Vimentin and Snail had negative correlations with miR-631, meaning that miR-631 could inhibit the process of epithelial–mesenchymal transition (EMT), which is widely considered to be crucial to the invasion-metastasis cascade during cancer progression (Figures 2J–L). The gene discussed is VIM; the disease is cancer.
