Among several subtypes of breast cancer, basal‐type breast cancer accounts for most triple‐negative breast cancers and shows a mesenchymal phenotype that is accompanied by high expression of mesenchymal genes including vimentin, and genes involved in the induction of epithelial‐mesenchymal transition (EMT; Neve et al., 2006; Sarrio et al., 2008). Here, VIM is linked to breast carcinoma.
