ABSTRACT

AIM:

To investigate the relationship betw een ADRP and the development of atherosclerosis.

METHODS:

Antisense oligodeoxynucleotide of mouse ADRP was constr ucted. The mouse peritoneum macrophages were cultured with Ox-LDL or Ox-LDL plus the antisense fragment. The cellular cholesterol was measured and the expressio n of ADRP was observed with RT-PCR and western blotting. New Zealand white rabbi ts were fed with high cholesterol chow for 12 weeks. The levels of serum lipid a nd cholesterol content of aortic wall were investigated. The areas of fatty stre ak of the aortas was measured after staining with Sudan Ⅳ. The aortic, and live r specimens with HE and immunohistochemistry staining were observed under light microscopes.

RESULTS:

Antisense oligodeoxynucleotides of mouse ADRP decreased cellular cholesterol ester, induced cellular lipid droplets and the expression of ADRP. The expression of ADRP was induced by high-cholesterol-diet feeding in rabbit atherosclerotic lesions. The fatty streak of the aorta with immunohistoch emistry staining was strongly positive for ADRP in animals fed with high cholest erol chow, and the liver was negative with or without high cholesterol chow.

CONCLUSIONS:

The expression of ADRP in vessel walls is related t o the atherosclerosis, and has a potential role in lipid accumulation in macroph ages and pathogenesis of atherosclerosis.
