Transcriptome-wide profile of 25-hydroxyvitamin D3 in primary immune cells from human peripheral blood

Project description:In this study, we used PBMCs of five healthy individuals participating in the VitDHiD intervention trial (NCT03537027) and investigated in a transcriptome-wide approach the gene regulatory potential of 25(OH)D3 and D3 in reference to 1,25(OH)2D3 (GSE156124).

Gene-regulatory potential of 25-hydroxyvitamin D3 and D2

Project description:In this study, we compared the modulation of the transcriptome of human PBMCs by the vitamin D metabolites 25-hydroxyvitamin D3 (25(OH)D3), 25(OH)D2 and 1α,25-dihydroxyvitamin D3 (1,25(OH)2D3).

Transcriptome-Wide Profile of 25-Hydroxyvitamin D3 in Primary Immune Cells from Human Peripheral Blood.

Project description:Vitamin D3 is an essential micronutrient mediating pleiotropic effects in multiple tissues and cell types via its metabolite 1α,25-dihydroxyvitamin D3 (1,25(OH)2D3), which activates the transcription factor vitamin D receptor. In this study, we used peripheral blood mononuclear cells (PBMCs) obtained from five healthy adults and investigated transcriptome-wide, whether the precursor of 1,25(OH)2D3, 25-hydroxyvitamin D3 (25(OH)D3), has gene regulatory potential on its own. Applying thresholds of >2 in fold change of gene expression and <0.05 as a false discovery rate, in this ex vivo approach the maximal physiological concentration of 25(OH)D3 (250 nM (nmol/L)) none of the study participants had a significant effect on their PBMC transcriptome. In contrast, 1000 and 10,000 nM 25(OH)D3 regulated 398 and 477 genes, respectively, which is comparable to the 625 genes responding to 10 nM 1,25(OH)2D3. The majority of these genes displayed specificity to the tested individuals, but not to the vitamin D metabolite. Interestingly, the genes MYLIP (myosin regulatory light chain interacting protein) and ABCG1 (ATP binding cassette subfamily G member 1) showed to be specific targets of 10,000 nM 25(OH)D3. In conclusion, 100- and 1000-fold higher 25(OH)D3 concentrations than the reference 10 nM 1,25(OH)2D3 are able to affect the transcriptome of PBMCs with a profile comparable to that of 1,25(OH)2D3.

Mapping Variation in Cellular and Transcriptional Response to 1,25-dihydroxyvitamin D3 in Peripheral Blood Mononuclear Cells

Project description:This study characterizes the genetic basis of variation in the immunomodulatory effects of the active form of vitamin D, 1,25-dihydroxyvitamin D3 (1,25D). This was done by mapping quantitative traits of 1,25D response both at the cellular and transcriptional level in peripheral blood mononuclear cells (PBMCs). Total RNA extraced from peripheral blood mononuclear cells from 85 healthy individuals of African-African ancestry treated with 1,25D or the vehicle control, ethanol, for 6 hours.

Comparison of cellular and transcriptional responses to 1,25-dihydroxyvitamin D3 and glucocorticoids in peripheral blood mononuclear cells

Project description:Glucocorticoids (GC) and 1,25-dihydroxyvitamin D3 (1,25(OH)2 D3) are steroid hormones with anti-inflammatory properties with enhanced effects when combined. We previously showed that transcriptional response to GCs was correlated with inter-individual and inter-ethnic cellular response. Here, we profiled cellular and transcriptional responses to 1,25(OH)2 D3 from the same donors. We studied cellular response to combined treatment with GCs and 1,25(OH)2 D3 in a subset of individuals least responsive to GCs. We found that combination treatment had significantly greater inhibition of proliferation than with either steroid hormone alone. Overlapping differentially expressed (DE) genes between the two hormones were enriched for adaptive and innate immune processes. Non-overlapping differentially expressed genes with 1,25(OH)2 D3 treatment were enriched for pathways involving the electron transport chain, while with GC treatment, non-overlapping genes were enriched for RNA-related processes. These results suggest that 1,25(OH)2 D3 enhances GC anti-inflammatory properties through a number of shared and non-shared transcriptionally-mediated pathways. Total RNA was obtained from aliquots of peripheral blood mononuclear cells treated with 1,25-dihydroxyvitamin D3 (1,25(OH)2 D3) for 8 and 24 hours. These data were analyzed together with previously published data from expression analysis of PBMC aliquots collected in parallel to these and treated with dexamethasone or vehicle (EtOH).
