Materials & Methods:
Cell cultivation and transfection: Wild-type and mutant E-cadherin cDNAs were isolated previously from non-tumourous gastric mucosa or somatic gastric carcinoma of the diffuse type and were expressed stably in MDA-MB-435S carcinoma cells (ATCC, Rockville, MD, USA) (10). Vector-transfected control MDA-MB-435S cells were obtained after transfection with the b-actin promoter-based pBATEM expression vector as described before (10). The cells were grown in Dulbecco’s modified Eagle’s medium (Life Technologies, Eggenstein, Germany) supplemented with 10% fetal calf serum (PAN-Biotech, Aidenbach, Germany) and penicillin–streptomycin (50 IU/ml and 50 mg/ml; Life Technologies) at 378C and 5% CO2. The MDA-MB-435S strain evolved from the parent line MDA-MB-435, which was isolated from the pleural effusion of a female with metastatic, ductal adenocarcinoma of the breast (68).
