Expression levels of N-Cadherin, Fibronectin and Vimentin were significantly downregulated (p < 0.05) in the tumours derived from the miR-200b-overexressing MDA-MB-231 (miR200) cells compared to the tumours from the control (Scram) counterparts (Fig. 6F–H, respectively). This evidence concerns the gene FN1 and neoplasm.
