Figure 1. The relationship between angiogenesis pathway score and angiogenesis regulatory factors in the TCGA and CGGA datasets. (A) Expression of VEGF-related genes (VEGFA, VEGFB, VEGFC, VEGFR1, VEGFR2, VEGFR3) in high- and low-score groups. (B) VWF (endothelial cell marker) expression in different groups. (C) Expression levels of ANGPT1, ANGPT2, JAM2, MCAM, PDGFRB, and VE-Cadherin in different groups. (D) Gene expression levels of hypoxia-related genes (HIF1A and HIF1B).
