It was also found that RES inhibited proliferation, migration, and invasion of human breast cancer cells exposed to cancer-associated fibroblast-conditioned media (CAF-CM) by suppressing the CAF-CM-induced expression of Cyclin D1, c-Myc, MMP-2 and MMP-9, Sox2 expression and also the activation of Akt and STAT3. This evidence concerns the gene AKT1 and breast cancer.
