AR and triple-negative breast carcinoma: Separate subtypes of triple negative breast cancer have been characterized by gene expression including two basal-like subtypes (BL1 and BL2), an immunomodulatory, mesenchymal, mesenchymal stem-like, luminal androgen receptor (LAR) subtypes and two additional subtypes that include claudin-low and interferon-rich.4,5,6 Basal breast cancer is characterized by a unique cluster of genes that includes the epidermal growth factor receptor (EGFR, also called HER1), basal cytokeratins 5/6 and c-Kit.7 About 70% of TNBC are basal type.
