| pubmed-article:19577079 | pubmed:abstractText | The inflammatory process of aortic stenosis involves the differentiation of aortic valve myofibroblasts into osteoblasts. Osteopontin, a proinflammatory glycoprotein, both stimulates differentiation of myofibroblasts and regulates the deposition of calcium by osteoblasts. Osteopontin levels are increased in patients with such conditions as end-stage renal disease, ectopic calcification, and autoimmune disease. We hypothesized that increased plasma osteopontin levels might be associated with the presence of aortic valve calcification and stenosis. | lld:pubmed |
