Additionally, TNBC cases (n = 14) had significantly increased NRP-1 expression in tumor tissue compared to the luminal B (n = 16, p = 0.043) and B-like (n = 14, p = 0.005) subtypes and higher PlGF expression compared to luminal B cases (n = 16, p = 0.026) (Fig. 2e–g, Table 2). Here, PGF is linked to neoplasm.
