Oleuropein and hydroxytyrosol activate <scp>GPER</scp>/ <scp>GPR</scp>30‐dependent pathways leading to apoptosis of <scp>ER</scp>‐negative <scp>SKBR</scp>3 breast cancer cells

Showing that OL and HT work as GPER inverse agonists in ER-negative and GPER-positive SKBR3 BC cells, we provide novel insights into the potential of these two molecules as tools in the therapy of this subtype of BC.
