15-Lipoxygenase-1 Is Involved in the Effects of Atorvastatin on Endothelial Dysfunction

Figure 2

Expression levels of AKT, eNOS, VCAM-1, and ICAM-1 were modulated by lentivirus-based ALOX15 overexpression in rat balloon-injured (BI) carotid arteries 14 days after transfection. (a) Immunohistochemical analysis of eNOS, VCAM-1, and ICAM-1 in BI carotid arteries. The arrows indicate positive staining. The scale bar represents 5 μm. (b) Western blot analysis of eNOS expression in BI carotid arteries. (c) Western blot analysis of p-AKT/p-eNOS expression in BI carotid arteries to assess the activity levels of AKT and eNOS. The protein level of p-eNOS was normalized against that of GAPDH because total eNOS expression was changed. (d) Western blot analysis of VCAM-1/ICAM-1 expression in BI carotid arteries. The scale bar represents 10 μm. Results are expressed as mean ± SD. Ator: atorvastatin; NS: not significant. versus the Sham group; and versus the BI group; and versus the BI + Lv-GFP group. per group.
