Calcitriol prevents in vitro vascular smooth muscle cell mineralization by regulating Calcium-Sensing Receptor expression.

In conclusion, these findings suggest that nanomolar concentrations of 1,25(OH)2D3 induce a CaSR-dependent protection against VC. Both lower and higher concentrations are either ineffective or may even promote VC. Whether this also holds true in the clinical setting requires further study.
