The 231/LM2-4 cell line was selected, as indicated, from the well characterized MDA-MB-231 human breast cancer cell line, which apart from the typical expression profile of triple negative tumors [48,49], expresses c-Met, cadherin-11 (similar to N-cadherin) and a mutant form of p-53 [50,51]. The gene discussed is MET; the disease is breast carcinoma.
