AR and neoplasm: Lehmann et al. by a recent gene analysis expression of TNBC identified at least 6 different tumor molecular subtypes including two basal-like (BL1 and BL2), an immunomodulatory (IM), a mesenchymal (M), a mesenchymal stem-like (MSL), and a luminal androgen receptor (LAR) subtypes, which appear to be driven by distinct pathways that may be effectively targeted by specific drugs in vitro [19].
