Additionally, as shown in Figure 6A, there were 102 targets overlapping between drug targets (Nar) and disease targets (diabetic angiopathies) in the Venn diagram (Figure 6A), with VEGFA (degree 51), Src (degree 45), and KDR (degree 30) being the core targets according to the degree value in the PPI network (Figure 6B). The gene discussed is VEGFA; the disease is diabetic peripheral angiopathy.
