SNX3 may reverse EMT of CRC cells by regulating β-catenin. (A) Protein expression levels of β-catenin were determined by western blotting. (B) β-catenin expression was semi-quantified. (C) Following transfection with sh-SNX3, the expression levels of β-catenin were detected by western blotting. (D) Protein expression levels of β-catenin and EMT-associated proteins in NC-HT29, shSNX3-HT29 and shSNX3-HT29-si-β-catenin cells were analyzed by western blotting with GAPDH as the loading control. (E) Transwell assays were performed to determine the migratory and invasive abilities of NC-HT29, shSNX3-HT29 and shSNX3-HT29-si-β-catenin cells; scale bar, 200 µm. *P<0.05; **P<0.01; ***P<0.001. EMT, epithelial-mesenchymal transition; NC, negative control; sh, small hairpin RNA; si, small interfering RNA; SNX3, sorting nexin 3.
