The Western blot was processed as previously described.12 (link) The primary antibodies used in the present study were listed below: wnt3a (1:1000, ab19925, Abcam), β-catenin (1:1000, 51067-2-AP, Proteintech), Vimentin (1:1000, 10366-1-AP, Proteintech), E-cadherin (1:500, 20874-1-AP, Proteintech), N-cadherin (1:500, 22018-1-AP, Proteintech), Fibronectin (1:500, 15613-1-AP, Proteintech), Snail (1:500, 13099-1-AP, Proteintech) and GAPDH (1:2000, 60004-1-Ig, Proteintech). The blots were developed using the ECL substrate (Beyotime, China) and photographed using the imaging system (Bio-Rad, CA, USA).
