miRNA-200c regulates paclitaxel resistance by suppressing EMT in A549/TAX cells. (A) Effects of miRNA-200c on CTSL, Snail, E-cadherin, N-cadherin, and vimentin were subjected to immunofluorescent microscopy. Images were captured using a 63× objective lens. (B and C) Effects of miRNA-200c on E-cadherin, N-cadherin, cytokeratin-18, Snail, and vimentin were assessed by Western blot analysis. At least three independent experiments were performed. *P<0.05, **P<0.01, and ***P<0.001 were compared with control.
