Objective: To determine the effect of renal denervation (RDN) on the severity of
atherosclerosis and aortic aneurysm in hypertensive mice. Methods: Hypertension,
atherosclerosis and aortic aneurysm were induced by subcutaneous infusion of
angiotensin II (1 ?g/kg/min) for 28 days in apolipoprotein E-deficient mice. RDN
was conducted using combined surgical and local chemical denervation. The
norepinephrine concentration in the kidney was measured by high-performance
liquid chromatography. Blood pressure was measured by the tail-cuff method.
Atherosclerosis was assessed by Sudan IV staining of the aortic arch. The aortic
diameter was measured by the morphometric method. The mRNA expression of genes
associated with atherosclerosis and aortic aneurysm were analyzed by quantitative
PCR. Results: RDN decreased the median norepinephrine content in the kidney by
93.4% (n = 5-7, P = 0.003) 5 days after the procedure, indicating that the RDN
procedure was successful. RDN decreased systolic blood pressure in apolipoprotein
E-deficient mice. Mice that had RDN had more severe aortic arch atherosclerosis
(median percentage of Sudan IV positive area: 13.2% in control mice, n = 12, and
25.4% in mice having RDN, n = 12, P = 0.028). The severity of the atherosclerosis
was negatively correlated with the renal norepinephrine content (spearman r =
-0.6557, P = 0.005). RDN did not affect the size of aortic aneurysms formed or
the incidence of aortic rupture in mice receiving angiotensin II. RDN
significantly increased the aortic mRNA expression of matrix metalloproteinase-2
(MMP-2). Conclusion: RDN promoted atherosclerosis in apolipoprotein E-deficient
mice infused with angiotensin II associated with upregulation of MMP-2. The
higher MMP-2 expression could be the results of the greater amount of atheroma in
the RDN mice. The findings suggest further research is needed to assess
potentially deleterious effects of RDN in patients.
