Our study showed an increased expression of mesenchymal biomarkers (ZEB1, Snail, Slug, N-cadherin, Vimentin and Fibronectin) and a decreased expression of epithelial biomarkers (ZO-1, E-cadherin, CK-8, CK-18 and CK-19) after INHBA overexpression, which indicate that INHBA overexpression could induce the EMT process in BC cells. This evidence concerns the gene TJP1 and breast cancer.
