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.

Analysis of the cellular effect of 1α,25-dihydroxyvitamin D3 on lung NCI-H441 cells

Project description:Low serum levels or deficiency of 1α,25-dihydroxyvitamin D3 (VD3) are associated with a higher mortality in trauma patients with sepsis or acute respiratory distress syndrome, although the molecular mechanisms behind this observation are not yet understood. VD3 is known to stimulate lung maturity, alveolar type II cell differentiation and pulmonary surfactant synthesis. This study aims to expand the knowledge by quantitative characterization of NCI-H441 cells upon VD3 treatment at the proteome level.

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).

Whole Transcriptome RNA Sequencing Detects Multiple 1a,25-Dihydroxyvitamin D3-Sensitive Metabolic Pathways in Zebrafish Embryos

Project description:Vitamin D receptors (VDR) are abundantly expressed in developing zebrafish as early as 48 hours post-fertilization, and prior to the development of a mineralized skeleton, and mature intestine and kidney. We probed the role of VDR in zebrafish biology by examining changes in expression of RNA by whole transcriptome shotgun sequencing (RNA-seq) in fish treated with picomolar concentrations of the VDR ligand and hormonal form of vitamin D3, 1a,25-dihydroxyvitamin D3 (1a,25(OH)2D3). We observed significant changes in RNAs encoding proteins of fatty acid, amino acid, and xenobiotic metabolism pathways, and RNAs of transcription factors, leptin, peptide hormones, receptor-activator of NFkB ligand (RANKL), and calcitonin-like ligand receptor pathways. Early small, and subsequent massive changes in >10% of expressed cellular RNAs were observed. At day 2 (24h 1a,25(OH)2D3-treatment), only 5 RNAs were differentially expressed (hormone vs. vehicle). On day 4 (72h-treatment), 78 RNAs; on day 6 (120h-treatment) 1040 RNAs; and on day 7 (144h-treatment), 1755 RNAs were differentially expressed in response to 1a,25(OH)2D3. Fewer RNAs (n = 482) were altered in day 7 embryos treated for 24h with 1a,25(OH)2D3 vs. those treated with hormone for 144h. At 7 days, in 1a,25(OH)2D3-treated embryos, pharyngeal cartilage was larger and mineralization was greater. Changes in expression of RNAs for transcription factors, peptide hormones, and RNAs encoding proteins integral to fatty acid, amino acid, leptin, calcitonin-like ligand receptor, RANKL and xenobiotic metabolism pathways, demonstrate heretofore unrecognized mechanisms by which 1a,25(OH)2D3 functions in vivo in developing eukaryotes.
