Methods and Results Apolipoprotein E-deficient mice were treated with recombinant adenovirus expressing human adiponectin (Ad-APN) or ß-galactosidase (Ad-ßgal). The plasma adiponectin levels in Ad-APNtreated mice increased 48 times as much as those in Ad-ßgal treated mice. On the 14th day after injection, the lesion formation in aortic sinus was inhibited in Ad-APNtreated mice by 30% compared with Ad-ßgaltreated mice (P<0.05). In the lesions of Ad-APNtreated mice, the lipid droplets became smaller compared with Ad-ßgaltreated mice (P<0.01). Immunohistochemical analyses demonstrated that the adenovirus-mediated adiponectin migrate to foam cells in the fatty streak lesions. The real-time quantitative polymerase chain reaction revealed that Ad-APN treatment significantly suppressed the mRNA levels of vascular cell adhesion molecule-1 by 29% and class A scavenger receptor by 34%, and tended to reduce levels of tumor necrosis factor-
without affecting those of CD36 in the aortic tissue.
Conclusions These findings documented for the first time that elevated plasma adiponectin suppresses the development of atherosclerosis in vivo.

In the present study, we investigated the therapeutic effects of adiponectin on the development of atherosclerosis in apolipoprotein E-deficient (apoE-/-) mice.

|---|
Animal Protocol
Male apoE-/- mice (Jackson Laboratory, Bar Harbor, Me) were fed a normal chow. At the age of 12 weeks, Ad-APN or Ad-ßgal was injected into tail vein (2.2x108 pfu each). The mice were anesthetized with an intraperitoneal injection of pentobarbital (50 mg/kg), and the hearts, which contained the aortic sinus and aortic arch, were harvested at the indicated time. This protocol was approved by the Institutional Laboratory Animal Care and Use Committee of Osaka University.
Plasma Data Analyses
Blood samples were collected from mice ad libitum on the fifth day after adenovirus injection. Total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and glucose levels were measured with enzymatic kits (Wako), and insulin levels were assayed with EIA kit (Glazyme). Human or mouse adiponectin levels were determined with adiponectin or Acrp30 ELISA kits (Otsuka Pharmaceutical Co Ltd).
Histochemical Analyses
The frozen cross-sections (10 µm thick) of aortic sinus embedded in Optimal Cutting Temperature (OCT; Sakura Finetechnical Co, Ltd) compound after overnight fixation in 10% formalin were mounted on slides. For the analysis of plaque size, the 3 sections (100 µm apart) from each mouse before and on the 14th day after adenovirus injection were stained with Oil Red O. The lesion size and the diameter of lipid droplets in the lesions were quantified with an image analyzing computer software, and the mean values were determined. For the immunohistochemical analyses, frozen sections, harvested on the fifth day after adenovirus injection, were incubated with the either rabbit anti-human adiponectin polyclonal antibody (OCT 9104, 2 µg/mL), rat anti-mouse macrophages (Mac-1) monoclonal antibody (Immunotec, 20 µg/mL), or mouse anti
-smooth muscle actin (
-actin) monoclonal antibody (DAKO, 1 µg/mL). The counter-staining for the nucleus was carried out with Mayers hematoxylin.
Gene Expression Analysis
To quantify expression of vascular cell adhesion molecule-1 (VCAM-1), class A scavenger receptor (SR-A), tumor necrosis factor-
(TNF-
) and CD36 in aortic tissue, the real-time quantitative polymerase chain reaction (TaqMan PCR, Perkin-Elmer) was performed as previously described.15 The cDNA was generated from 2 µg total RNA isolated from the upper half of the heart and aortic arch with an oligo dT oligodeoxynucleotide primer (T1218). The mRNA levels of target genes were divided by those of cyclophilin A, a standard control gene, and normalized. The values in Ad-APNtreated aortas are expressed as a relative percentage compared with those in Ad-ßgal treated aortas.
Data and Statistical Analysis
Data are presented as mean±SEM and were analyzed by Students t test or the Mann-Whitney U test, depending on their distribution pattern. A value of P<0.05 was considered statistically significant.

To assess the role of elevated plasma adiponectin in atherosclerotic lesion formation, the localization of adenovirus-derived human adiponectin, macrophages, and smooth muscle cells were analyzed immunohistochemically on the fifth day after adenovirus injection. Adenovirus-derived human adiponectin abundantly adhered to Mac-1 positive and
-actin negative cells in the fatty streak lesions (Figure 2A).
|
To further assess the mechanism of lesion reduction, the mRNA levels of VCAM-1, SR-A, TNF-
, and CD36 were quantified. Ad-APN treatment significantly suppressed the mRNA levels of VCAM-1 (100±10.3 versus 70.9±4.8%, P<0.05) and SR-A (100±10.0 versus 65.8±9.2%, P<0.05, and tended to reduce those of TNF-
(100±33.6 versus 63.1±15.2%) without affecting those of CD36 in the aortic tissue (100±4.5 versus 100.2±13.0%) (Figure 2B).
| Discussion |
|---|
|
|
|---|
We previously reported that human recombinant adiponectin suppressed nuclear factor-
B inducible gene expression including VCAM-1 in human aortic endothelial cells and SR-A expression in human monocyte-derived macrophages.8,12,14 The recombinant protein did not affect CD36 expression in macrophages.12 Adiponectin treatment dose-dependently decreased the uptake of modified low-density lipoprotein.12 In the present study, the Ad-APN treatment actually inhibited the expression of VCAM-1 and SR-A without affecting that of CD36 in vivo. VCAM-1 and SR-A play a pivotal role in the development of atherosclerosis. The expression of VCAM-1 localized over the surface of endothelial cells in lesion-prone sites, and the targeted disruption of SR-A reduced the size of atherosclerotic lesions in apoE-/- mice.19,20 Therefore, our findings suggest that the elevated plasma adiponectin protected endothelial cells from hypercholesterolemia-induced vascular injury and suppressed the uptake of modified low-density lipoprotein into foam cells in apoE-/- mice.
The hypo-adiponectinemia was observed in patients with CAD and was associated with the incidence of cardiovascular death.8,10 This study documented for the first time that the overexpression of adiponectin actually reduced atherosclerosis through attenuating endothelial inflammatory response and macrophage to foam cell transformation in vivo. Therefore, in future studies, this model of adiponectin gene transfection will be useful to determine the therapeutic level of plasma adiponectin for preventing atherosclerosis.
