Prenatal vitamin D deficiency alters immune cell proportions of offspring in young adult age [scRNA-seq]

ABSTRACT: Vitamin D deficiency is a common micronutrient deficiency worldwide, especially among reproductive-age women, and vitamin D deficiency during pregnancy increases the risks of offspring’s immune-related diseases later in life. The mechanisms of how our body remembers the exposure status of an adverse environment during development have not been fully elucidated yet. Here we show that prenatal vitamin D deficiency exposure alters the immune cell proportion of the offspring at the prenatal and adult stage, which is attributed to transcriptional alterations of vitamin D receptor downstream genes. Further, we assessed the association between maternal vitamin D status and cord blood immune cell profiles from 75 healthy mother and their term baby pairs and found that maternal vitamin D deficiency significantly alters immune cell proportion in cord blood. Our findings demonstrate that prenatal vitamin D deficiency alters the immune cell compositions of offspring by changing the transcriptional properties of stem cells and altering long-term stem cell fate decisions.

Vitamin D deficiency during development permanently alters liver cell composition and function.

Project description:Vitamin D, a fat-soluble vitamin, plays a critical role in calcium homeostasis, the immune system, and normal development. Many epidemiological cohort studies globally have found high prevalence rates of vitamin D deficiency and insufficiency, recognized as an important health issue that needs to be solved. In particular, reproductive age and pregnant women low in vitamin D status may confer risks of diseases like obesity on their offspring. While observational studies have suggested associations between prenatal vitamin D deficiency and metabolic phenotypes in offspring, not yet determined is whether prenatal vitamin D deficiency permanently alters the development of the liver, a major metabolic organ. We tested the histopathology and the transcriptomic profiles of livers from male C57BL/6J mice exposed to prenatal vitamin D deficiency through a maternal dietary intervention model. We found that prenatal vitamin D deficiency increases the prevalence of histopathological changes in the liver, and alters its gene expression profile. Cell subtype proportion analysis showed that the liver of prenatal vitamin D deficiency alters non-parenchymal cells of the liver, specifically macrophages, a subset of endothelial cells, and dendritic cells. Our results indicate the long-term memory of prenatal vitamin D deficiency exposure in the adult liver, a potential contributor to offspring health risks.

Transcription profiling of mouse offspring of crosses between hypercholesterolemic and normocholesterolemic parents LUMC-HKG-ApoE-Atherosclerosis

Project description:Enhanced prenatal fatty streak formation in human fetuses has been associated with maternal hypercholesterolemia. However, the possible roles of maternal genetic background and in utero environment on development of atherosclerosis in adult life have not been unraveled. We generated genetically identical heterozygous apoE-deficient mice offspring with a different maternal background to study the intrauterine effect of maternal genotype and associated hypercholesterolemia on the developing vascular system. As read out for increased atherosclerosis development in adult life, a constrictive collar was placed around the carotid artery to induce lesion formation. A significant increase in endothelial cell activation and damage was detected in the carotid arteries of heterozygous apoE-deficient fetuses with apoE-deficient mothers compared with offspring from wild type mothers, but no fatty streak formation was observed. Postnatally, all carotid arteries revealed normal morphology. In adult offspring with maternal apoE-deficiency, the constrictive collar resulted in severe lesion (9/10) development compared with no to only minor lesions (2/10) in offspring of wild type mothers. Microarray analysis showed no effect of maternal apoE-deficiency on gene expression in adult offspring. We conclude that maternal apoE-deficiency not only affects fetal arteries, but also increases the susceptibility for development of collar-induced atherosclerosis in adult life. Experiment Overall Design: Crossing of hypercholesterolemic female with normocholesterolemic male and vice versa, determination of susceptabilioty to atherosclerosis in offspring

Maternal Vitamin D deficiency induces transcriptomic changes in newborn rat lungs

Project description:Transcriptomic analysis of lungs from newborn rats born to vitamin D adequate and vitamin D deficient mothers Vitamin D deficiency during pregnancy is common and is related to several maternal and fetal morbidities. Past studies suggest that vitamin D plays a role in normal lung development and we have shown that vitamin D regulates lung alveolar and vascular growth and preserves lung structure in experimental bronchopulmonary dysplasia (BPD) through improved pro-angiogeneic signaling. In addition, maternal vitamin D deficiency causes abnormal airway, alveolar, and vascular growth, as well as impaired lung function and airway hyper-reactivity in newborn rats. However, the mechanisms responsible for these physiologic effects are unknown. To gain insight into the role that maternal vitamin D status has on fetal lung development we used an unbiased transcriptomic approach to identify pathways altered in the lungs of offspring from vitamin D deficient dams.
