Note: VDR is a log scale. log of 5.6 is 1/10 of log of 6.6

Background and aims: Epidemiological studies have shown that subnormal levels of vitamin D (25(OH)D) are associated with a more aggravated clinical course of ulcerative colitis (UC). Despite an increased focus on the therapeutic importance of vitamin D and vitamin D receptor (VDR) signaling, the mechanisms underlying the effects of the vitamin D-VDR axis on UC remain elusive. Therefore, we aimed to investigate whether exposure to active vitamin D (1,25(OH)2D3)/VDR signaling in human organoids could influence the maintenance of the colonic epithelium.

Methods: Intestinal VDR expression was studied by immunohistochemistry, RNA expression arrays, and single-cell RNA sequencing of colonic biopsy specimens obtained from patients with UC and healthy individuals. To characterize the functional and transcriptional effects of 1,25(OH)2D3, we used patient-derived colonic organoids. The dependency of VDR was assessed by knocking out the receptor with CRISPR/Cas9.

Results: Our results suggest that 1,25(OH)2D3/VDR stimulation supports differentiation of the colonic epithelium and that impaired 1,25(OH)2D3/VDR signaling thereby may compromise the structure of the intestinal epithelial barrier, leading to flares of UC. Furthermore, a transcriptional response to VDR activity was observed primarily in fully differentiated cells at the top of the colonic crypt, and this response was reduced during flares of UC.

Conclusions: We identified an important role of vitamin D signaling in supporting differentiated cell states in the human colonic epithelium, and thereby maintenance of the intestinal barrier integrity. This makes the vitamin D-VDR signaling axis an interesting target for therapeutic efforts to achieve and maintain remission in patients with UC.

VitaminDWiki – The Vitamin D Receptor is associated with many health problems

530 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: 48 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

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
