(a) Representative immunoblots of insulin receptor (insulin R), insulin-like growth factor-1 receptor (IGF-1 R), phospho-protein kinase B (p-Akt), protein kinase B (Akt), phospho-endothelial nitric oxide synthase (p-eNOS), endothelial nitric oxide synthase (eNOS), and actin extracted from thoracic aortas, and relative protein quantification of (b) insulin R, (c) IGF-1 R, (d) p-Akt/Akt, and (e) p-eNOS/eNOS on the basis of actin among the WKY, SHR, and SHR+PCA groups. α, p < 0.05, significant differences from WKY; β, p < 0.05, significant differences from SHR; n = 6 in each group.
