Note: Breast Cancer appears to be able to mutate the VDR so as to prevent being having to defend itself against Vitamin D
So, many times BC ==> deactivate VDR, instead of Deactivated VDR ==> Breast Cancer

Breast cancer is the leading cause of death among women worldwide. It is a multi-factorial disease caused by genetic and environmental factors. Vitamin D has been hypothesized to lower the risk of breast cancer via the nuclear vitamin D receptor (VDR). Genetic variants of these vitamin D metabolizing genes may alter the bioavailability of vitamin D, and hence modulate the risk of breast cancer.

MATERIALS AND METHODS:
The distribution of Fok1 VDR gene (rs2228570) polymorphism and its association with breast cancer was analysed in a case–control study based on 125 breast cancer patients and 125 healthy females from North Indian population, using PCR-RFLP. An In silico exploration of the probable mechanism of increased risk of breast cancer was performed to investigate the role of single nucleotide polymorphisms (SNPs) in cancer susceptibility.

RESULTS:
The Fok1 ff genotype was significantly associated with an increased risk of breast cancer (p=0.001; χ2=13.09; OR = 16.909; %95 CI=2.20 - 130.11). In silico analysis indicated that SNPs may lead to a loss in affinity of VDR to calcitriol, and may also cause the impairment of normal interaction of liganded VDR with its heterodimeric partner, the retinoid X receptor (RXR), at protein level, thereby affecting target gene transcription.

CONCLUSION:
Breast cancer risk and pathogenesis in females can be influenced by SNPs. SNPs in VDR may cause alterations in the major molecular actions of VDR, namely ligand binding, heterodimerization and transactivation. VDRE binding and co-activator recruitment by VDR appear to be functionally inseparable events that affect vitamin D-elicited gene transcription. This indicates that breast cancer risk and pathogenesis in females may be influenced by SNPs.

Vitamin D Receptor category has the following

533 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: 49 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 (19 studies), Breast Cancer (24 studies), Colon Cancer (14 studies), Cardiovascular (23 studies), Cognition (16 studies), Diabetes (24 studies), Hypertension (9 studies), Infant (22 studies), Lupus (6 studies), Metabolic Syndrome (4 studies), Mortality (4 studies), Multiple Sclerosis (15 studies), Obesity (17 studies), Pregnancy (24 studies), Rheumatoid Arthritis (10 studies), TB (8 studies), VIRUS (37 studies),   Click here for details
Some health problems, such as Breast Cancer, Diabetes, and COVID protect themselves by reducing VDR activation

How to increase VDR activation

Compensate for poor VDR by increasing one or more:

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
12) Infrequent high concentration Vitamin D Increases the concentration gradient	Vitamin D Receptor
13) Sulfroaphane and perhaps sulfur	Vitamin D Receptor
14) Butyrate especially gut	Vitamin D Receptor
15) Berberine	Vitamin 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
