title: [The bone-vasculature-axis interaction: new insights into the pathogenesis of vascular calcification.].
abstract: It is commonly accepted that the first cause of morbidity and mortality in chronic kidney disease (CKD) is the cardiovascular (CV) disease, in which vascular calcification (VC) plays a central pathogenetic role. In CKD population, mineral metabolism disorders have been recently investigated not only as key factors on renal osteodystrophy but also as inducing players on extra-skeletal calcification. Clearly, either high phosphate (P) or high calcium (Ca) concentration induce vascular smooth muscle cells mineralization in vitro studies. In fact, VC is induced by a cell-mediated process, which actively accompanies the traditional and passive Ca-P deposition in arterial walls. Interestingly, lack of inhibitory proteins, such as fetuin-A (alpha2-HS glycoprotein, AHSG), matrix GLA protein (MGP), osteoprotegerin (OPG), and bone morphogenetic protein 7 (BMP-7) are the regulatory key factors in preventing VC in uremic conditions.
