We have recently demonstrated expression of a functional calcium sensing receptor (CaSR) in human aortic smooth muscle cells (HAoSMC) and human arteries and demonstrated a correlation between CaSR expression and medial calcification (a major cause of cardiovascular mortality in chronic kidney disease). Apoptosis of vascular SMC occurs early in the development of calcification and apoptotic bodies accumulate calcium. Here, we have examined CaSR-mediated signalling pathways in H...

Accelerated medial calcification is a major cause of premature cardiovascular mortality in people with chronic kidney disease. Evidence suggests that the concentration of extracellular Ca2+ and vascular smooth muscle cells play a pivotal role in the pathogenesis of vascular calcification. Extracellular Ca2+ is detected by the calcium-sensing receptor (CaSR). The CaSR is a G protein-coupled receptor that is expressed in a range of tissues, but characteriza...
