The results are shown in Figure 4, where we, interestingly, found significant associations between NRP1 expressions and tumor–immune response in immune lymphocytes (Figure 4A), chemokines (Figure 4B), receptors (Figure 4C), immune inhibitors (Figure 4D), immunostimulators (Figure 4E), and major histocompatibility complex (MHC) molecules (Figure 4F) in most pan-cancers. The gene discussed is HLA-C; the disease is neoplasm.
