Abstract：
:Medial arterial calcification involves chondrogenic/osteogenic transdifferentiation of vascular smooth muscle cells (VSMCs). Zhao et al. report that phosphate activates the mammalian target of rapamycin (mTOR) cascade in VSMCs, leading to downregulation of Klotho. Furthermore, rapamycin was shown to halt medial calcification. This effect was blunted in the absence of Klotho. Given the concomitant anti-atherosclerotic effects of the mTOR inhibitor, this agent has clinical potential as an inhibitor of intimal atherosclerosis and medial calcification.
