Abstract
Taxanes are mainstay treatment of triple negative breast cancer (TNBC) patients but resistance often develops. Using TNBC patient-derived orthoxenografts (PDX) we have recently discovered that a CD49f+ chemoresistant population with tumor-initiating ability is present in sensitive tumors and expands in tumors that have acquired resistance. Importantly, sensitivity to taxanes is recovered after long-term drug interruption. The characterization of this chemoresistant CD49f+ cells provides a unique opportunity to identify novel targets for the treatment of chemoresistant TNBC.Entities:
