Highlights

  • A positive correlation between transcript level of MYH, MTH1, OGG1, ITPA with NRF2 mRNA level in PBMCs of MS patients.
  • In silico analysis revealed putative AREs at OGG1, MYH, ITPA, and MTH1 promoter sequences that were considered as NRF2 consensus sequences in humans.
  • Impact of VD on MS patients may be mediated through the improvement of DNA repair system efficiency.
VitaminDWiki

Vitamin D has be used to succesfully treat Multiple Sclorosis for over 10 years.
This study identifies a possible mechanism
Over 20,000 people with Multiple Sclerosis use high-dose vitamin D to virually eliminate their symptoms

Multiple Sclerosis 32 percent less likely among those with more than 32 ng of vitamin D – Dec 2019

UV and Sunshine reduces MS risk

Other things also help

High Dose Vitamin D and cofactors

Number of MS studies which are also in other categories

  • 22 studies in Genetics - genes can restrict Vitamin D getting to the blood and to the cells
  • 12 studies in Vitamin D Receptor - gene which restricts D from getting to the cells
  • 7 studies in Vitamin D Binding Protein - gene which restricts D from getting to the cells
  • 21 studies in Ultraviolet light - may be even better than Vitamin D in preventing and treating MS
  • 9 studies in Omega-3 - which helps Vitamin D prevent and treat MS


Oxidative stress (OS) plays an essential role in demyelination and tissue injury related to pathogenesis of multiple sclerosis (MS). On the other hand, vitamin D (VD) as an antioxidant reduces oxidative stress and has been used as adjuvant therapy in autoimmune diseases. Although VD supplementation is suggested as a protective and immunomodulation factor for MS patients, the molecular mechanisms remain unclear. Given that VD may modulate the immune system of MS patients through the DNA repair pathway, we aimed to evaluate the effects of VD supplementation in DNA repair genes expression including OGG1, MYH, MTH1, and ITPA. Transcript levels were measured using the RT-qPCR method in peripheral blood mononuclear cells (PBMCs) of relapsing-remitting multiple sclerosis (RRMS) patients before and after two months of VD supplementation. Furthermore, in silico analysis and correlation gene expression analysis was performed to find the biological binding sites and the effect of NRF2 on the regulation of DNA repair genes.

Our data revealed that in MS patients, 2‐month VD treatment significantly altered the expression of MYH, OGG1, MTH1, and NRF2 genes. A significant correlation was observed between DNA repair genes and NRF2 expression, which was confirmed by the presence of antioxidant response element (ARE) binding sites in the promoter of OGG1, MYH, and MTH1 genes. This study demonstrated that the impact of VD on MS patients may be mediated through the improvement of DNA repair system efficiency. This finding brought some new evidence for the involvement of DNA repair genes in the physiopathology of MS patients.
