Estradiol modulates gene expression in the monkey iliac artery

ABSTRACT: Objective: To examine the effect of estradiol on gene expression in the monkey iliac arteries. Design: Eight ovariectomized cynomolgus monkeys were on a high fat diet for 6.5 years. The left iliac artery was biopsied before randomization to estradiol (1 mg Estrace® per day, n=4) or vehicle (n=4) for 8 months. The right iliac artery was obtained at necropsy. Gene expression in the iliac arteries in response to estradiol was determined by DNA microarray and confirmed by real time RT-PCR. Results: Atherosclerotic lesions in the iliac arteries ranged in size from 0-0.61 mm2 in estrogen-treated animals and from of 0-0.873 mm2 in controls. 106 genes were shown to be down-regulated and 26 genes were up-regulated in the monkey iliac arteries in response to estradiol. Among the genes shown
