Rheumatoid arthritis, genes and vitamin D – May 2013

The aim of this study was to explore the role of vitamin D in rheumatoid arthritis (RA) pathogenesis by investigating the enrichment of vitamin D response elements (VDREs) in confirmed RA susceptibility loci and testing variants associated with vitamin D levels for association with RA. Bioinformatically, VDRE genomic positions were overlaid with non-HLA (human leukocyte antigen)-confirmed RA susceptibility regions.

The number of VDREs at RA loci was compared to a randomly selected set of genomic loci to calculate an average relative risk (RR).
Single-nucleotide polymorphisms (SNPs) in the DHCR7/NADSYN1 (nicotinamide adenine dinucleotide synthase 1) and CYP2R1 loci, previously associated with circulating vitamin D levels, were tested in UK RA cases (n=3870) and controls (n=8430).

Significant enrichment of VDREs was seen at RA loci (P=9.23 × 10−8) when regions were defined either by gene (RR 5.50) or position (RR 5.86).
SNPs in the DHCR7/NADSYN1 locus showed evidence of positive association with RA, rs4944076 (P=0.008, odds ratio (OR) 1.14, 95% confidence interval (CI) 1.03–1.24).

The significant enrichment of VDREs at RA-associated loci and the modest association of variants in loci-controlling levels of circulating vitamin D supports the hypothesis that vitamin D has a role in the development of RA.

Vitamin D Receptor category has the following

463 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: 44 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
- - - - - - - -
The Vitamin D Receptor is associated with many health problems

Health problems include: Autoimmune (17 studies), Breast Cancer (20 studies), Colon Cancer (12 studies), Cardiovascular (22 studies), Cognition (16 studies), Diabetes (22 studies), Hypertension (6 studies), Infant (18 studies), Lupus (6 studies), Metabolic Syndrome (3 studies), Mortality (4 studies), Multiple Sclerosis (11 studies), Obesity (15 studies), Pregnancy (22 studies), Rheumatoid Arthritis (10 studies), TB (8 studies), VIRUS (30 studies),   Click here for details
Some health problems, such as Breast Cancer and Diabetes, protect themselves by reducing VDR activation
Suspect that SAR-COV-2 also protects itself from Vitamin D

55 health problems associated with poor VDR


A poor VDR is associated with the risk of 55 health problems  click here for details
The risk of 45 diseases at least double with poor VDR as of Nov 2022  click here for details
Some health problem, such as Breast Cancer reduce the VDR

VDR at-home test $29 - results not easily understood in 2016
There are hints that you may have inherited a poor VDR


How to increase VDR activation


Compensate for poor VDR by increasing one or more:

IncreasingIncreases
1) Vitamin D supplement  Sun
Ultraviolet -B
Vitamin D in the blood
and thus in the cells
2) MagnesiumVitamin 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 VDRVitamin D Receptor
9) BoronVitamin D Receptor ?,
etc
10) Essential oils e.g. ginger, curcuminVitamin D Receptor
11) ProgesteroneVitamin D Receptor
12) Infrequent high concentration Vitamin D
Increases the concentration gradient
Vitamin D Receptor
13) Sulfroaphane and perhaps sulfurVitamin D Receptor
14)Butyrate especially gutVitamin D Receptor

Note: If you are not feeling enough benefit from Vitamin D, you might try increasing VDR activation. You might feel the benefit within days of adding one or more of the above

Far healthier and stronger at age 72 due to supplements Includes 6 supplements that help the VDR
