Ductal breast carcinoma‐derived triple‐negative HCC1143 cell line was used to demonstrate mesenchymal morphology (Fig. 3) with high vimentin detection in the cytoplasm, nuclear localization of p53, and cytoplasmic distribution of the basal‐like breast cancer marker cytokeratin 5 36, 37. Here, KRT5 is linked to breast ductal adenocarcinoma.
