Tumor tissue sections were treated with 1% H2O2, blocked with 1% FBS (Gibco, CA, USA), and immunostained with anti-E-cadherin (1:1000; Cell Signaling Technology, MA, USA) or anti-Vimentin (1:500; Sigma-Aldrich, MO, USA) for 12 h at 4°C. After that, tumor tissue sections were incubated with a secondary antibody (1:500; Cell Signaling Technology) for 2 h at 25°C. All sections were developed by 3,3’-diaminobenzidine (DAB) kit (Thermo Scientific, CA, USA) [36 (link)].
