Treatment of experimental human breast cancer and lung cancer brain metastases in mice by macitentan a dual antagonist of endothelin receptors combined with paclitaxel

摘要

BackgroundWe recently demonstrated that brain endothelial cells and astrocytes protect cancer cells from chemotherapy through an endothelin-dependent signaling mechanism. Here, we evaluated the efficacy of macitentan, a dual endothelin receptor (ETAR and ETBR) antagonist, in the treatment of experimental breast and lung cancer brain metastases.
