Vitamin D receptor: A highly versatile nuclear receptor

Vitamin D receptor (VDR) modulators are used to treat hyperparathyroidism secondary to chronic kidney disease (CKD). The therapy is associated with reduced mortality in stage 5 CKD patients, who experience an extremely high cardiovascular disease (CVD)-related mortality rate. Chen et al. report that VDR is involved in regulating type A natriuretic peptide receptor (NPR-A) in inner medullary collecting duct cells. The regulation of NPR-A may be one of several mechanisms by which VDR activation reduces CVD risk in CKD.
