It was observed that the treatment of miR-200b significantly abrogated the AP-2α/MAPK7/TGF-β expression (Fig. 5c–e), leading to increased expression of E-cadherin and TTF-1 and decreased expression of fibronectin and α-SMA in tumor tissues (Fig. 5f–i). This evidence concerns the gene TGFB1 and neoplasm.
