To better understand and further characterize the molecular mechanisms by which TGFβ promotes cellular migration in BLBC, we performed genomic profiling in BLBC and identified Ephrin type-A receptor 4 (EPHA4), a member of the erythropoietin-producing hepatocellular (Eph) receptor family as a novel target of TGFβ in breast cancer. The gene discussed is EPHA4; the disease is breast carcinoma.
