Analysis with TIMER showed strong correlation between NRP1 expression and the abundance of tumor progression-related genes, MMP1, MMP3, MMP9, VEGFC, FLT4 and CXCL12 in LUSC, while there isn’t clear association between NRP1 expression and this panel of pro-tumorigenic genes in LUAD (Figure 5C, Supplementary Figure 5). The gene discussed is CXCL12; the disease is neoplasm.
