Background and purpose: Atherosclerosis is a major cause of death in adults in most countries.
Many studies have focused on the protective role and anti-inflammatory properties of adiponectin but its
role in calcification has been less studied. Studies that could determine the causes and mechanisms of
calcification could be of great value. The aim of this study was to investigate the effects of adiponectin on
osteonectin gene expression, a protein involved in vascular calcification.
Materials and methods: In this experimental study, vascular smooth muscle cells were obtained
from Pasteur Institute of Iran and were cultured in F12K medium containing β-glycerophosphate as
calcifying stimuli. The cells were treated with 5μg/ml adiponectin. At 24 and 48 hours osteonectin gene
expression in these cells was studied against control cells using real time PCR.
Results: We observed that adiponectin increased osteonectin gene expression against control
cells 2.17 and 3.6 fold in vascular smooth muscle cells at 24 and 48 hours, respectively.
Conclusion: Increasing the expression of osteonectin gene lead to increases in calcification,
therefore, adiponectin could be considered as a risk factor for atherosclerosis.
