Abstract

Osteoprotegerin (OPG) is a secreted member of the tumor necrosis factor receptor family, and in previous studies has been shown to regulate osteoclast activity and differentiation. Ablation of the OPG gene in mice results in calcification of the aorta and renal arteries. We have previously reported an association between a single nucleotide polymorphism in the promoter region of OPG and vascular morphology and function in healthy humans. The objective with this study was to confirm our previous results in a larger population, and in addition, to study subjects with hypertension. The OPG genotype was determined by restriction fragment length and the intima-media thickness (IMT) of the common carotid artery was measured by ultrasound in 100 patients with hypertension and left ventricular hypertrophy, and 75 healthy normotensive control subjects. In the hypertensive group subjects with the CC genotype (n=24) showed a significantly increased IMT compared to those with the TC (n=52, p=0.007) and TT (n=24, p=0.009) genotype, in the hypertensive group only (mean +/- SD for TT=0.88 +/- 0.21 mm, TC=0.90 +/- 0.16 mm, CC=1.05 +/- 0.31 mm). The allele distribution did not differ between hypertensive and control individuals. The present stu...Continue Reading
