Moreover, in breast cancer MCF-7 and MDA-MB-231 cells, quercetin treatment inhibited epithelial-mesenchymal transition determined by expression of markers such as vimentin, Snail, N-cadherin, Twist, Slug, MMP2, and MMP9, by suppressing EGFR/VEGFR2 signaling [72]. This evidence concerns the gene MMP9 and breast carcinoma.
