Figure 6: VNS protects vascular endothelial function. (a) Representative examples of eNOS, ICAM-1, and VCAM-1 expression in different groups. (b) Relative expression levels are shown as the ratio between the target proteins and β-actin expression levels. vs. control group; vs. I/R group. eNOS: endothelial nitric oxide synthase; ICAM-1: intercellular cell adhesion molecule-1; VCAM-1: vascular cell adhesion molecule-1.
