Project description:Pregnancy 25-hydroxyvitamin D (25(OH)D) concentrations are associated with maternal and fetal health outcomes, but the underlying mechanisms have not been elucidated. Using physiological human placental perfusion approaches and intact villous explants we demonstrate a role for the placenta in regulating the relationships between maternal 25(OH)D concentrations and fetal physiology. Here, we demonstrate active placental uptake of 25(OH)D3 by endocytosis and placental metabolism of 25(OH)D3 into 24,25-dihydroxyvitamin D3 and active 1,25-dihydroxyvitamin D [1,25(OH)2D3], with subsequent release of these metabolites into both the fetal and maternal circulations. Active placental transport of 25(OH)D3 and synthesis of 1,25(OH)2D3 demonstrate that fetal supply is dependent on placental function rather than solely the availability of maternal 25(OH)D3. We demonstrate that 25(OH)D3 exposure induces rapid effects on the placental transcriptome and proteome. These map to multiple pathways central to placental function and thereby fetal development, independent of vitamin D transfer, including transcriptional activation and inflammatory responses. Our data suggest that the underlying epigenetic landscape helps dictate the transcriptional response to vitamin D treatment. This is the first quantitative study demonstrating vitamin D transfer and metabolism by the human placenta; with widespread effects on the placenta itself. These data show complex and synergistic interplay between vitamin D and the placenta, and inform possible interventions to optimise placental function to better support fetal growth and the maternal adaptations to pregnancy.

Project description:In humans, vitamin D3 is a secosteroid, a prohormonal precursor of biologically active hydroxyforms. Vitamin D3 is related to periodontitis. The third American Health and Nutrition Survey found that plasma 25(OH)D3 levels are negatively correlated with attachment loss in people aged >50 years. The relationship between vitamin D3 and periodontitis remains to be investigated. We sent human gingival fibroblasts treated by vitamin D3 for transcriptome sequencing.

Project description:Vitamin D insufficiency is a global epidemic and despite its high incidence the impact of Vitamin D signaling beyond calcium-bone regulation is not fully understood. To expand our analysis of the impact of 1,25(OH)D3 on hematopoietic stem and progenitor cell (HSPC) production and function in zebrafish and human umbilical cord blood (hUCB), we performed a microarray study to indentify signaling pathways downstream of 1,25(OH)D3 stimulation in hUCB CD34+ cells.

Project description:Vitamin D’s ability to prevent colorectal cancer (CRC) has been suspected for nearly 30 years, but has never been directly studied in humans. The biologically active version of vitamin D, 1,25(OH)2D3, cannot be readily used in humans because of its tendency to cause serum calcium levels to rise. In contrast, 25(OH)D3 (ie calcifediol) does not have this side effect. The investigators previous research suggests that the enzyme necessary to convert 25(OH)D3 (calcifediol) into active 1,25(OH)D3 is present in cells lining the large intestine (colon).
Aberrant crypt foci (ACF) are very small (ie microscopic) collections of abnormally shaped cells that are a commonly used marker of CRC risk. Screening colonoscopy at UIC routinely uses methods that allow ACF counting to be done as a part of standard practice. ACF’s are not fixed, like polyps or cancers, but can disappear as a person’s risk for developing CRC decreases.
The investigators propose giving patient’s with 10 or more ACF’s 25(OH)D3 (calcifediol) or placebo, and determining if there is a drug-dependant decrease in ACF number. The primary objective is to determine whether 25(OH)D3 (calcifediol) supplementation, compared to placebo, causes significant reduction of ACF number from baseline levels. The primary endpoint will be change in ACF number.

Project description:WM164, a human melanoma line, was a gift from Dr M. Herlyn (Wistar Institute, Philadelphia, PA, USA). The cells were cultured using DMEM media supplemented with 10% serum (fetal bovine serum while growing cells and charcoal-treated serum during incubation with vitamin D compounds), 1% antibiotics and 5 g/mL insulin (Sigma-Aldrich, St. Louis, MO, USA). Cells were cultured in 75 cm2 plastic bottles (TPP–Techno Plastic Products AG, Trasadingen, Switzerland) with a filter in an incubator at 37 C with 5% CO2. CRISPR/Cas Knock out of the VDR. The clustered regularly interspaced short palindromic repeats (CRISPR) genetic engineering method was carried out to knock out VDR expression in the WM164 cell line as described in (Cancers 2021, 13, 3111. https://doi.org/10.3390/cancers13133111). The resulting cells with the VDR gene knocked out are designated as WM164 VDR KO, and the cells transduced with an “empty” lentivirus served as a control (WM164 scramble). VDR expression was checked for scramble and VDR KO lines before experiments were performed and further every 4 months after lentivirus treatment to ensure that VDR was not expressed in the WM164 KO. Sources of Vitamin D3 Compounds: Both 1,25(OH)2D3 and 25(OH)D3 were purchased from Sigma. 1,20(OH)2D3 and 20(OH)D3 were chemically synthesized. RNA SEQ: VDR-KO or scramble WM164 cells were plated onto 100 mm2 Petri dishes and treated with 1,25(OH)2D3, 25(OH)D3, 20(OH)D3, 1,20(OH)2D3 or ethanol (control) in triplicates. Cells were incubated in 10% charcoal-treated serum for 24 h. Cells were further harvested and RNA isolated using Absolutly RNA Miniprep Kit (Stratagen) . Approximately 120 ng/ul of each sample was sent for RNAseq analysis. BGI@CHOP genomics company sequenced the samples on Illumina HiSeq TM, analyzed, and sent us the results.
