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.

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
15) BerberineVitamin 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
