Summary: Eribulin is an approved therapy for the treatment of breast cancer which has been shown to reverse the epithelial-to-mesenchymal transition (EMT) and improve the efficacy of standard chemotherapies in cell lines, animal studies, and clinical specimens. Tumour EMT status has also been linked to eribulin efficacy. Based on this, we evaluated the effects of eribulin in patient-derived breast cancer cultures and a triple-negative breast cancer cell line to assess changes to EMT and therapy response. We further identified the induction of epithelial-like characteristics, including E-cadherin expression in a patient-derived HER2+ primary tissue with a predominantly mesenchymal phenotype following longitudinal eribulin exposure. Additionally, we compared EMT marker expression in breast cancers treated with standard-of-care neoadjuvant docetaxel, Adriamycin and cyclophosphamide (TAC) therapy with that observed in the neoadjuvant eribulin clinical trial.
