25-dihydroxyvitamin D [1,25(OH)2D]. 1,25(OH)2D interacts with its nuclear receptor to modulate gene expression 

and biological actions. The vitamin D receptor (VDR) is present in a wide variety of cells including enterocytes, 

osteoblasts, and renal tubular cells. Vitamin D is crucial for proper functions of a wide variety of organ systems, and 

its deficiency is highly prevalent in the general population and also among kidney stone formers.
