According to recent research, oleic acid inhibits the growth of breast cancer stem cells (MDA-MDB-231, MCF-7 cell lines); it decreases MRP1 and β-catenin levels, suppresses the invasion and metastasis, through the induction of ROS (reactive oxygen species), and down-regulates FAK/AKT/NF-κB signaling pathways [270]. This evidence concerns the gene AKT1 and breast carcinoma.
