Multiple sclerosis cuprizone mouse model and vitamin D supplementation


ABSTRACT: Dietary supplementation of vitamin D is commonly recommended to patients with multiple sclerosis (MS). We investigated the effect of 1,25-dihydroxyvitamin-D3 (1,25-(OH)2D3) on the brain proteome in the cuprizone model during remyelination. Mice were demyelinated with dietary cuprizone for 7 weeks. The mice received intra-peritoneal injections of 1,25-(OH)2D3 or placebo twice a week, from week 6 and throughout week 10. Brain samples were taken after 7 weeks (demyelinated), after 8 weeks (1 week remyelination) and after 10 weeks (3 weeks of remyelination). The six experimental groups were labeled with TMT, mixed mode HPLC fractionation, and applied to LC-MS which enabled quantification of 5062 proteins with high confidence.

Dietary supplementation of vitamin D is commonly recommended to patients with multiple sclerosis. We recently found that high-dose of the hormonally active 1,25-dihydroxyvitamin-D<sub>3</sub> (1,25D) promotes myelin repair in the cuprizone model for de- and remyelination. In the present study, we quantified 5062 proteins, of which 125 were differentially regulated in brain tissue from 1,25D treated mice during remyelination, compared to placebo. Proteins upregulated in the early remyelination ph  ...[more]
