Figure 2 (Top) Western blot of endothelial nitric oxide synthase III (NOSIII) in cells exposed to the following conditions: A = untreated cells; B = native low-density lipoprotein; C = glycosylated low-density lipoprotein (glycLDL); D = oxidized low-density lipoprotein (oxLDL); E = glyc-oxLDL; F = oxLDL (second form); and G = glyc-oxLDL (second form). All concentrations are 100 µg/ml. (Bottom) Densitometric analysis of endothlelial NOSIII levels (mean ± SD) representative of six separate experiments. Endothelial NOSIII was significantly decreased in C (*p < 0.01 vs. B) and E (#p < 0.0001 vs. B and C). Similarly, G was significantly decreased compared with F (**p < 0.0004 vs. F).
