To that end we assessed the METABRIC50 breast cancer cohort, using ELF3 expression to stratify patients into three categories: ‘high’ (Upper quartile of ELF3 expression), ‘mid’ (Inter quartile range of ELF3 expression), and ‘low’ (Lower quartile of ELF3 expression). The gene discussed is ELF3; the disease is breast carcinoma.
