Maternal Vitamin D deficiency induces transcriptomic changes in newborn rat lungs

ABSTRACT: 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.
