TAZ is required for metastatic activity and chemoresistance of breast cancer stem cells

2015

Metastatic growth in breast cancer (BC) has been proposed as an exclusive property of cancer stem cells (CSCs). However, formal proof of their identity as cells of origin of recurrences at distant sites and the molecular events that may contribute to tumor cell dissemination and metastasis development are yet to be elucidated. In this study, we analyzed a set of patient-derived breast cancer stem cell (BCSC) lines. We found that in vitro BCSCs exhibit a higher chemoresistance and migratory potential when compared with differentiated, nontumorigenic, breast cancer cells (dBCCs). By developing an in vivo metastatic model simulating the disease of patients with early BC, we observed that BCSCs…

Erythropoietin activates cell survival pathways in breast cancer stem-like cells to protect them from chemotherapy

2013

Abstract Recombinant erythropoietin (EPO) analogs [erythropoiesis-stimulating agents (ESA)] are clinically used to treat anemia in patients with cancer receiving chemotherapy. After clinical trials reporting increased adverse events and/or reduced survival in ESA-treated patients, concerns have been raised about the potential role of ESAs in promoting tumor progression, possibly through tumor cell stimulation. However, evidence is lacking on the ability of EPO to directly affect cancer stem–like cells, which are thought to be responsible for tumor progression and relapse. We found that breast cancer stem–like cells (BCSC) isolated from patient tumors express the EPO receptor and respond to …

Prevention of chemotherapy-induced anemia and thrombocytopenia by constant administration of stem cell factor.

2011

Abstract Purpose: Chemotherapy-induced apoptosis of immature hematopoietic cells is a major cause of anemia and thrombocytopenia in cancer patients. Although hematopoietic growth factors such as erythropoietin and colony-stimulating factors cannot prevent the occurrence of drug-induced myelosuppression, stem cell factor (SCF) has been previously shown to protect immature erythroid and megakaryocytic cells in vitro from drug-induced apoptosis. However, the effect of SCF in vivo as a single myeloprotective agent has never been elucidated. Experimental Design: The ability of SCF to prevent the occurrence of chemotherapy-induced anemia and thrombocytopenia was tested in a mouse model of cisplat…
