Triple-negative breast cancer (TNBC) is biologically aggressive and has limited systemic treatment options, often compounded by treatment resistance.
Cell state transitions, e.g. epithelial-to-mesenchymal transition (EMT) govern cancer cell behaviour.
The investigators hypothesize that by inducing change in cell state change, TNBC cells that have manifested taxane-resistance will be more sensitized to subsequent chemotherapy.
