One study examined EVs derived from MDA-MB-231 BC cells, finding that MCF-7, BT474 and HCC1937 BC cell survival under doxorubicin, cisplatin and fulvestrant treatment respectively is significantly increased following EV-mediated transfer of miR-887-3p, BTB domain containing 7 (BTBD7) suppression and Notch signalling activation in recipient cells. This evidence concerns the gene BTBD7 and breast cancer.
