Kallikrein 1(KLK1), histamine receptor 1 (HRH1), neuropilin 2 (NRP2), amyloid precursor protein (APP) and ephrin- B1 (EFNB1) were clearly differentially overexpressed in basal and HER2-enriched tumor samples, neural growth factor receptor (NGFR) expression in the MicMa cohort was associated to basal-like subtypes (Figure 4). Here, NRP2 is linked to neoplasm.
