As controls, a non-invasive luminal breast cancer cell line MCF-7 express E-cadherin but no mesenchymal markers, whereas MDA-MB-231 and Hs578T two known invasive breast cancer cell lines lack E- and P-Cadherin expression but express some of the mesenchymal markers tested (Fig. 3). The gene discussed is CDH1; the disease is breast carcinoma.
