Vitamin D Receptor
It appears that 1/3 of everyone with a vitamin D-related disease has a poor VDR
A poor VDR cannot be detected by any standard Vitamin D test (nor Calcitriol nor Calcidiol)
A poor Parathyroid VDR can be detected when high Calcitriol levels fail to decrease PTH levels
- Decreasing PTH shows Vitamin D is getting to Parathyroid - but says nothing about VDRs elsewhere
Many cancers and viruses have learned to protect themselves by deactivating the local VDR
A VDR activation decreases with age
Vitamin D Receptor Overview
studies in Vitamin D Receptor category
Vitamin D tests cannot detect Vitamin D Receptor (VDR) problems
A poor VDR restricts Vitamin D from getting in the cells
See also: studies in the Resveratrol category
It appears that 30% of the population have a poor VDR (40% of the Obese )
Several diseases protect themselves by deactivating the Vitamin D receptor. Example: Breast Cancer

| Increasing | Increases |
| 1) Vitamin D supplement Sun Ultraviolet -B | Vitamin D in the blood and thus in the cells |
| 2) Magnesium | Vitamin D in the blood AND in the cells |
| 3) Omega-3 | Vitamin D in the cells |
| 4) Resveratrol | Vitamin D Receptor |
| 5) Intense exercise | Vitamin D Receptor |
| 6) Get prescription for VDR activator paricalcitol, maxacalcitol? | Vitamin D Receptor |
| 7) Quercetin (flavonoid) | Vitamin D Receptor |
| 8) Zinc is in the VDR | Vitamin D Receptor |
| 9) Boron | Vitamin D Receptor ?, etc |
| 10) Essential oils e.g. ginger, curcumin | Vitamin D Receptor |
| 11) Progesterone | Vitamin D Receptor |

OBJECTIVES:
The vitamin D receptor (VDR) is a member of the nuclear receptor family of transcription factors. We examined whether degree of VDR gene methylation acts as a molecular adaptation to light exposure. We explored this in the context of photoperiod at conception, recent UV irradiance at 305 nm, and gene-latitude effects.
METHODS:
Eighty subjects were examined for VDR gene-CpG island methylation density. VDR gene variants were also examined by PCR-RFLP.
RESULTS:
Photoperiod at conception was significantly positively related to VDR methylation density, explaining 17% of the variance in methylation (r2 = 0.17; P = .001). Within this model, photoperiod at conception and plasma 25(OH)D independently predicted methylation density at the VDR-CpG island. Recent UV exposure at 305 nm led to a fivefold increase in mean methylation density (P = .02). Again, UV exposure and plasma 25(OH)D independently predicted methylation density at the VDR-CpG island. In the presence of the BsmI mutant allele, methylation density was increased (P = .01), and in the presence of the TaqI or FokI mutant allele, methylation density was decreased (P = .007 and .04 respectively). Multivariate modeling suggests plasma 25(OH)D, photoperiod at conception, recent solar irradiance, and VDR genotype combine as independent predictors of methylation at the VDR-CpG island, explaining 34% of the variance in methylation (R2 = 0.34, P < .0001).
CONCLUSIONS:
Duration of early-life light exposure and strength of recent irradiance, along with latitudinal genetic factors, influence degree of VDR gene methylation consistent with this epigenetic phenomenon being a molecular adaptation to variation in ambient light exposure. Findings contribute to our understanding of human biology.

RXR (and retinol) is needed to produce proteins with the VDR. 1,25D3 binds to the VDR, which then combines with RXR to activate gene expression. (Not all VDR-dependent genes need RXR.)
SIRT1 -potentiates VDR [R, R] – acetylation of VDR lessens 1,25D/VDR signaling. SIRT1 increased the ability of VDR to associate with RXR.
PGC-1a [R]– potentiates VDR. It is a coactivator of the VDR, but it still needs 1,25D3.
Dopamine [R]
The VDR evolved from its ancient role as a detoxification nuclear receptor. LCA is produced from the gut bacteria (metabolizing liver-derived chenodeoxycholic acid). LCA travels to the colon, where the VDR binds to LCA or 1,25 D and activates the CYP3A4 and SULT2A genes facilitate disposal from the cell via the ABC efflux transporter [R].
Omega-3: DHA, EPA [R], – Fish oil/DHA
Omega-6: γ-Linolenic acid, Arachidonic acid [R],
Curcumin[R]– Curcumin is more active than LCA/Bile in driving VDR-mediated transcription and that it binds to VDR with approximately the same affinity as LCA.
Resveratrol[R] – Potentiates VDR by: (1) potentiating 1,25D binding to VDR; (2) activating RXR; (3) stimulating SIRT1.
Gamma Tocotrienol [R]- Tocotrienols or Tocopherols (IHERB)
Estradiol increases VDR expression [R, R] and calcitriol levels [R].
