Protein extraction and Western blot were performed as previously described.12 (link) Antibodies targeting GAPDH (Abcam, ab8245, 1:1000), β-actin (CST, 4970, 1:1000), TP531NP2 (Biovision, A1169-100, 1:500), Vimentin (CST, 5741, 1:1000), E-cadherin (CST, 3195, 1:1000), N-cadherin (CST, 13,116, 1:1000), β-catenin (CST, 8480, 1:1000), non-phospho (active) β-catenin (CST, 19,807, 1:1000), Snail1 (Affinity, AF6032, 1:500), and Histone H3 (Affinity, AF0863, 1:500) were used with the secondary antibody horseradish peroxidase-labeled goat antirabbit (CST, 7074, 1:4000) or anti-mouse (CST, 7076, 1:4000) and incubated at room temperature for 1 h. The protein bands were visualized using enhanced chemiluminescence.
