This study investigates whether targeting the miR-200c/FOXP3 axis can suppress metastasis in breast cancer.<h4>Methods</h4>Metastatic (MDA-MB-361, MDA-MB-468) and non-metastatic (MCF-7) breast cancer cell lines were transfected with miR-200c mimic or inhibitor. This evidence concerns the gene FOXP3 and breast cancer.
