Figure 3 Bar graph illustrating vascular endothelial growth factor expression in the coronary arterial wall from animals fed a normal diet (N, n = 4) or high cholesterol diet without (HC, n = 3) or with endothelin-type-A receptor antagonism (HC + ET-A, n = 3) for 12 weeks. Vascular endothelial growth factor protein content was higher in the HC group than in the N group (p = 0.06) and significantly lower in the HC + ET-A group than in the HC group. *p < 0.05. Values are mean ± standard error.
