Eribulin mesilate suppresses experimental metastasis of breast cancer cells by reversing phenotype from epithelial-mesenchymal transition (EMT) to mesenchymal-epithelial transition (MET) states.

ABSTRACT:

Background

Eribulin mesilate (eribulin), a non-taxane microtubule dynamics inhibitor, has shown trends towards greater overall survival (OS) compared with progression-free survival in late-stage metastatic breast cancer patients in the clinic. This finding suggests that eribulin may have additional, previously unrecognised antitumour mechanisms beyond its established antimitotic activity. To investigate this possibility, eribulin's effects on the balance between epithelial-mesenchymal transition (EMT) and mesenchymal-epithelial transition (MET) in human breast cancer cells were investigated.

Methods

Triple negative breast cancer (TNBC) cells, which are oestrogen receptor (ER-)/progesterone receptor (PR-)/human epithelial growth receptor 2 (HER2-) and have a mesenchymal pheno
