Abstract
Background Vitamin D is a hormone regulating gene transcription. Prenatal vitamin D has been linked to immune and vascular function in the placenta, a key organ of pregnancy. To date, studies of vitamin D and placental gene expression have focused on a limited number of candidate genes. Transcriptome-wide RNA sequencing can provide a more complete representation of the placental effects of vitamin D. Objective We investigated the association between prenatal vitamin D levels and placental gene expression in a large, prospective pregnancy cohort. Methods Participants were recruited in Shelby County, Tennessee in the Conditions Affecting Neurocognitive Development and Learning in Early childhood (CANDLE) study. Vitamin D level (plasma total 25-hydroxyvitatmin D, [25(OH)D]) was measured at mid-pregnancy (16-28 weeks' gestation) and delivery. Placenta samples were collected at birth. RNA was isolated and sequenced. We identified differentially expressed genes (DEGs) using adjusted linear regression models. We also conducted weighted gene co-expression network analysis (WGCNA). Results The median 25(OH)D of participants was 21.8 ng/mL at mid-pregnancy (N=774, IQR: 15.4-26.5 ng/mL) and 23.6 ng/mL at delivery (N=753, IQR: 16.8-29.1 ng/mL). Placental expression of 25 DEGs was associated with 25(OH)D at mid-pregnancy, but no DEG was associated with 25(OH)D at delivery. DEGs were related to energy metabolism, cytoskeletal function, and RNA transcription. Using WGCNA, we identified 2 gene modules whose expression was associated with 25(OH)D at mid-pregnancy and 1 module associated with 25(OH)D at delivery. These modules were enriched for genes related to mitochondrial and cytoskeletal function, and were regulated by transcription factors including ARNT2, BHLHE40, FOSL2, JUND, and NFKB1. Conclusions Our results indicate that 25(OH)D during mid-pregnancy, but not at delivery, is associated with placental gene expression at birth. Future research is needed to investigate a potential role of vitamin D in programming placental mitochondrial metabolism, intracellular transport, and transcriptional regulation during pregnancy.

Maternal vitamin D and E intakes during early pregnancy are associated with airway epithelial cell responses in neonates. Clin Exp Allergy 2016; 45:920-927.

Abstract
BACKGROUND Antenatal factors including maternal diet may predispose to airway disease, possibly by impacting on fetal airway development. OBJECTIVE This cohort study tested the hypothesis that maternal vitamin D and E status in early pregnancy is associated with airway epithelial cell (AEC) responses in new born infants and examined constitutive and TNFα/IL-1β, house dust mite (HDM) extract or lipopolysaccharide (LPS)-stimulated neonatal AEC responses in vitro. METHODS Maternal dietary vitamin D and E intakes (plasma 25[OH]D3 or α-tocopherol) were characterized at 10-12 weeks gestation. Neonatal nasal AECs were collected soon after birth and cultured to tertiary passage. Constitutive and stimulated - TNFα/IL-1β, HDM extract or LPS - secretory responses (VEGF, RANTES, MCP-1, IL-17A, IFN-γ, GM-CSF, eotaxin, MIP1-α, MIP1-β, ICAM, IL-6, IL-8, IL-10, TNF) in 139 AEC cultures were quantified. RESULTS AEC mediator release was greater following TNF-α/IL-1β, HDM or LPS stimulation compared to constitutive release. Increased maternal dietary vitamin D was associated with significant increases in IL-10 release by AEC after stimulation with TNF-α/IL-1β (P = 0.024) or HDM (P = 0.049). Maternal plasma α-tocopherol at 10-12 weeks gestation was positively associated with MIP1α (Spearman's rho 0.242, P = 0.009) and IL-3 (ρ 0.189, P = 0.043) responses after TNF-α/IL-1β stimulation and negatively associated with TNF (ρ -0.404, P = 0.011) and MIP1β (ρ -0.322, P = 0.046) responses after LPS stimulation. DISCUSSION Neonatal AECs respond to pro-inflammatory and allergenic stimuli in vitro demonstrating their potential to function as components of the innate immune response. Our findings suggest that associations exist between maternal micronutrient intake during early pregnancy and aspects of stimulated neonatal airway epithelial cell secretory function that may in turn impact on the development of asthma and/or allergic rhinitis in later life.

Abstract
Systemic scleroderma (SSc) is one of the most complex systemic autoimmune diseases. It targets the vasculature, connective tissue-producing cells (namely fibroblasts/myofibroblasts), and components of the innate and adaptive immune systems. Clinical and pathologic manifestations of SSc are the result of: (1) innate/adaptive immune system abnormalities leading to production of autoantibodies and cell-mediated autoimmunity, (2) microvascular endothelial cell/small vessel fibroproliferative vasculopathy, and (3) fibroblast dysfunction generating excessive accumulation of collagen and other matrix components in skin and internal organs. All three of these processes interact and affect each other. The disease is heterogeneous in its clinical presentation that likely reflects different genetic or triggering factor (i.e., infection or environmental toxin) influences on the immune system, vasculature, and connective tissue cells. The roles played by other ubiquitous molecular entities (such as lysophospholipids, endocannabinoids, and their diverse receptors and vitamin D) in influencing the immune system, vasculature, and connective tissue cells are just beginning to be realized and studied and may provide insights into new therapeutic approaches to treat SSc.

Abstract
The prevalence of asthma and other atopic disorders continues to increase worldwide. Examination of the epidemiologic patterns has revealed that this rise has occurred primarily in western, industrialised countries and countries transitioning to this lifestyle. While many changes have occurred in human populations over the years, it has been hypothesised that some of the relevant changes that have led to the rise in asthma and atopic disorders have been the changes from a traditional diet to a more western diet consisting of decreased intake of fruits and vegetables (sources of antioxidant vitamins and carotenoids) leading to decreased intakes of vitamins E and A, and a decrease in sun exposure (e.g. greater time spent indoors and heavy use of sunscreen) leading to decreased circulating levels of vitamin D. This review will examine the evidence for an effect of fat-soluble vitamins (vitamins A, D and K) on the development and severity of asthma and allergies. While observational studies suggest that these vitamins may play a salutary role in asthma and allergies, large, well-designed clinical trials are lacking. Of the fat-soluble vitamins, vitamin D holds great promise as an agent for primary and secondary prevention of disease. Ongoing clinical trials will help determine whether results of observational studies can be applied to the clinical setting.

Abstract
PURPOSE OF REVIEW Vitamin D deficiency has been rediscovered as a public-health problem worldwide. It has been postulated that vitamin D deficiency may explain a portion of the asthma epidemic. The purpose of this review is to present the evidence for a role of vitamin D in asthma. RECENT FINDINGS Both animal models and studies in human fetal tissues show that vitamin D plays a role in fetal lung growth and maturation. Epidemiologic studies have also suggested that higher prenatal vitamin D intakes have a protective role against wheezing illnesses in young children. Vitamin D may protect against wheezing illnesses through its role in upregulating antimicrobial proteins or through its multiple immune effects. In addition, vitamin D may play a therapeutic role in steroid resistant asthmatics, and lower vitamin D levels have recently been associated with higher risks for asthma exacerbations. SUMMARY Improving vitamin D status holds promise in primary prevention of asthma, in decreasing exacerbations of disease, and in treating steroid resistance. However, the appropriate level of circulating vitamin D for optimal immune functioning remains unclear. Because vitamin D deficiency is prevalent even in sun-replete areas, clinical trials are needed to definitively answer questions about the role of vitamin D in asthma.

Abstract
This study examines the effects of 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] on SH-SYSY human neuroblastoma cells cultured in the presence of medium containing varying concentrations of calcium (0.1, 0.9, 1.4, 1.8 mM). Pyruvate kinase activity was assayed in SH-SY5Y cells incubated in variable calcium medium with or without 1, 10 or 100 nM 1,25(OH)2D3 for 48 h. The enzyme levels showed a significant increase in comparison with control, when the cells were incubated with 100 nM hormone in the presence of 0.1 mM calcium, while pyruvate kinase activity decreased, when the cells were treated with 100 nM 1,25(OH)2D3 in the presence of 1.8 mM calcium. The proliferative activity of SH-SY5Y was dependent on the extracellular concentration of calcium, being the highest at 1.8 mM calcium and completely absent at 0.1 mM calcium. In the presence of 1,25(OH)2D3, at the three concentrations used and after 48 h incubation, a significant decrease in cell number was always observed, without a direct correlation between 1,25(OH)2D3 effect and calcium concentration in the medium. [3H]Thymidine incorporation in SH-SY5Y cells significantly increased in comparison with control, when the 48 h incubation with 1, 10 or 100 nM 1,25(OH)2D3 was carried out in the presence of 0.1 mM calcium, while, at the other calcium concentrations, the hormone did not cause any significant change in this parameter. The treatment of SH-SYSY cells with 1 nM 1,25(OH)2D3 for 48 h did not affect cell morphology, when 0.1 mM calcium was present, while, in the medium containing 1.8 mM calcium, the treated cells showed a slight trend to differentiation. The differentiating effect of 10 microM all-trans retinoic acid, even if incomplete after 48 h treatment, was only observed in the cultures grown in 1.8 mM calcium, in comparison with those maintained in 0.1 mM calcium.

Abstract
The response of IMR-90 human fetal lung fibroblasts at high population doubling level (PDL > 42) to 1,25-dihydroxyvitamin D3[1,25(OH)2D3] was investigated to clarify whether some metabolic and molecular parameters of senescent cells are affected by the hormone treatment. Pyruvate kinase, lactate dehydrogenase and glucose-6-phosphate dehydrogenase activity significantly increased after treatment of confluent-phase cells with 10 nM 1,25(OH)2D3 for 24 h. Steroid specificity was established by the failure of 10 nM levels of 25-hydroxyvitamin D3 to affect the enzyme activities, while estradiol-17 beta and progesterone produced a slight increase in glucose-6-phosphate dehydrogenase and lactate dehydrogenase levels, respectively. 1,25(OH)2D3 also affected fibroblast proliferation, protein content/cell and DNA synthesis. The cell number significantly decreased after a 48 h incubation with 1,25(OH)2D3 at various concentrations (0.01-1 nM) when compared with control fibroblasts, while an increase in the protein content/cell was demonstrated. The same experiment, carried out by protracting the incubation with the hormone for 72 h, showed a similar trend, but 10 nM 1,25(OH)2D3 was also able to inhibit cell proliferation and to stimulate protein synthesis. The incorporation of [3H]thymidine into DNA increased after the treatment of high PDL fibroblasts with 0.01-1 nM of hormone for 48 h in comparison with controls.
