Therapeutic effects of the soluble epoxide hydrolase (sEH) inhibitor AUDA on atherosclerotic diseases.

PMID 25975094


In this study, we aimed to detect the effects of the soluble epoxide hydrolase (sEH) inhibitor 12-(3-adamantan-1-yl-ureido)-dodecanoic acid (AUDA) on atherosclerotic diseases and to explore its mechanism. The atherosclerosis animal model was constructed by ApoE-/- mice. To determine the optimal therapeutic concentration of AUDA, different concentrations of AUDA were infused into ApoE-/- mice, with controls receiving infusions of normal saline alone. Mouse body weight and serum total cholesterol, triglyceride, LDL and HDL levels were measured. The western blotting (WB) method was used to detect the expression of TLR4 and NFKB in the aortic wall of the AUDA-treated and control mice. After the animals were sacrificed, we performed Oil Red O staining of the aortic sinus atherosclerotic plaque area followed by quantitative analysis of the aortic atherosclerotic plaque size and the percentage of lumen area in the two groups of mice. The expression levels of inflammatory cytokines, adhesion molecules and chemokines in the AUDA group were significantly decreased compared to the saline-treatment group (P < 0.05). The optimal AUDA concentration was found to be 0.35 ml/mg. AUDA significantly inhibited the expression of TLR4 and NFκB in ApoE-/- mouse aortas and reduced the aortic sinus plaque area of the ApoE-/- mouse group (P < 0.05). In conclusion, AUDA can regulate blood lipid balance, which may be one of the mechanisms for its protective effects on the cardiovascular system.
