TJP1 and lung cancer: In agreement with the correlation analysis between β3 integrin and EMT markers, β3 integrin-overexpressing lung cancer cells showed increased mesenchymal markers, including N-cadherin, vimentin, and ZEB1 (Fig. 2e, f); however, only small reductions were observed in E-cadherin, OVOL1, and ZO-1 (Fig. 2f).
