The vitamin D receptor (VDR also known as the calcitriol receptor) is a member of the nuclear receptor family of transcription factors. [5] Calcitriol (the active form of vitamin D, 1,25-(OH)2vitamin D3) binds to VDR, which then forms a heterodimer with the retinoid-X receptor. The VDR heterodimer then enters the nucleus and binds to Vitamin D responsive elements (VDRE) in genomic DNA. VDR binding results in expression or transrepression of many specific gene products. VDR is also involved in microRNA-directed post transcriptional mechanisms. [6] In humans, the vitamin D receptor is encoded by the VDR gene located on chromosome 12q13.11. [7]

VDR is expressed in most tissues of the body, and regulates transcription of genes involved in intestinal and renal transport of calcium and other minerals. [8] Glucocorticoids decrease VDR expression. [8] Many types of immune cells also express VDR. [9]

Function

The VDR gene encodes the nuclear hormone receptor for vitamin D. The most potent natural agonist is calcitriol (1,25-dihydroxycholecalciferol) and the vitamin D2 homologue ercalcitriol, 1-alpha,25-dihydroergocalciferol) is also a strong activator. Other forms of vitamin D bind with lower affinity, as does the secondary bile acid lithocholic acid. The receptor belongs to the family of trans-acting transcriptional regulatory factors and shows similarity of sequence to the steroid and thyroid hormone receptors. [10]

Downstream targets of this nuclear hormone receptor include many genes involved in mineral metabolism. [8] The receptor regulates a variety of other metabolic pathways, such as those involved in the immune response and cancer. [9] VDR variants that bolster vitamin-D action and that are directly correlated with AIDS progression rates and VDR association with progression to AIDS follows an additive model. [11] FokI polymorphism is a risk factor for enveloped virus infection as revealed in a meta-analysis. [12] The importance of this gene has also been noted in the natural aging process were 3’UTR haplotypes of the gene showed an association with longevity. [13]

Clinical relevance

Mutations in this gene are associated with type II vitamin D-resistant rickets. A single nucleotide polymorphism in the initiation codon results in an alternate translation start site three codons downstream. Alternative splicing results in multiple transcript variants encoding the same protein. [14] VDR gene variants seem to influence many biological endpoints, including those related to osteoporosis [15]

The vitamin D receptor plays an important role in regulating the hair cycle. Loss of VDR is associated with hair loss in experimental animals. [16] Experimental studies have shown that the unliganded VDR interacts with regulatory regions in cWnt (wnt signaling pathway) and sonic hedgehog target genes and is required for the induction of these pathways during the postnatal hair cycle. [17] These studies have revealed novel actions of the unliganded VDR in regulating the post-morphogenic hair cycle.

Researchers have focused their efforts in elucidating the role of VDR polymorphisms in different diseases and normal phenotypes such as the HIV-1 infection susceptibility and progression or the natural aging process. The most remarkable findings include the report of VDR variants that bolster vitamin-D action and that are directly correlated with AIDS progression rates, that VDR association with progression to AIDS follows an additive model [11] and the role of FokI polymorphism as a risk factor for enveloped virus infection as revealed in a meta-analysis. [12]

Interactions

Vitamin D receptor has been shown to interact with many other factors which will affect transcription activation:

Calcitriol is the active form of vitamin D, normally made in the kidney. It is also known as 1,25-dihydroxycholecalciferol. It is a hormone which binds to and activates the vitamin D receptor in the nucleus of the cell, which then increases the expression of many genes. Calcitriol increases blood calcium (Ca2+) mainly by increasing the uptake of calcium from the intestines.

<span class="mw-page-title-main">Calcitroic acid</span> Chemical compound

Calcitroic acid (1α-hydroxy-23-carboxy-24,25,26,27-tetranorvitamin D3) is a major metabolite of 1α,25-dihydroxyvitamin D3 (calcitriol). Around 1980, scientists first reported the isolation of calcitroic acid from the aqueous extract of radioactively treated animals' livers and intestines. Subsequent researches confirmed calcitroic acid to be a part of enterohepatic circulation. Often synthesized in the liver and kidneys, calcitroic acid is generated in the body after vitamin D is first converted into calcitriol, an intermediate in the fortification of bone through the formation and regulation of calcium in the body. These pathways managed by calcitriol are thought to be inactivated through its hydroxylation by the enzyme CYP24A1, also called calcitriol 24-hydroxylase. Specifically, It is thought to be the major route to inactivate vitamin D metabolites. The hydroxylation and oxidation reactions will yield either calcitroic acid via the C24 oxidation pathway or 1,25(OH2)D3-26,23-lactone via the C23 lactone pathway.
