Impaired Mineral Ion Metabolism in a Mouse Model of Targeted Calcium-Sensing Receptor (CaSR) Deletion from Vascular Smooth Muscle Cells

Martin Schepelmann (group Enikö Kallay) and national and international colleagues and collaborators have just published a study in the Journal of the American Society of Nephrology (JASN), one of the highest ranked and most prestigious journals in the nephrology field.

The Calcium-Sensing Receptor (CaSR) is a protein which is best known for its role in maintaining mineral ion homeostasis in the blood. In this study, the role of this protein in blood vessels was investigated by characterizing a mouse in which the CaSR had been genetically deleted from vascular smooth muscle cells. They found that these mice suffer from a profound mineral ion imbalance, specifically hypercalcemia, hypercalciuria, and hyperphosphaturia. As kidney and parathyroid functions were normal, these results suggest a hitherto unknown mode how blood vessels contribute to mineral ion homeostasis control.
