WebVitamin D activity is mediated through binding of 1,25(OH)2D3 to the vitamin D receptor (VDR), which can regulate transcription of other genes involved in cell regulation, growth, and immunity. VDR modulates the expression of genes by forming a heterodimer complex with retinoid-X-receptors (RXR). WebCalcifediol, also known as calcidiol, 25-hydroxycholecalciferol, or 25-hydroxyvitamin D 3 (abbreviated 25(OH)D 3), is a form of vitamin D produced in the liver by hydroxylation of vitamin D 3 (cholecalciferol) by the enzyme vitamin D 25-hydroxylase. Calcifediol can be further hydroxylated by the enzyme 25(OH)D-1α-hydroxylase, primarily in the kidney, to …
