Project description:Maternal diabetes is associated with a wide range of fetal and neonatal adverse effects including pulmonary disturbances. To investigate the effects of maternal diabetes on neonatal lung gene expression profile, we performed microarray analysis on the lungs of 14-day-old rats born to diabetic dam. Keywords: disease state analysis Four neonatal lungs exposed to maternal diabetes and four control lungs were analyzed.

Project description:Intrahepatic cholestasis of pregnancy (ICP) is estimated to impact between 0.4% and 5% of pregnancies worldwide. This disease is associated with elevated maternal bile acids and frequently untoward neonatal outcomes such as respiratory distress and asphyxia. Multiple candidate genes have been implicated, but none have provided insight into the mechanisms of neonatal respiratory distress and death. Herein our studies demonstrate that maternal cholestasis (due to Abcb11 deficiency) produces 100% neonatal death within 24h due to atelectasis producing pulmonary hypoxia, which recapitulates the respiratory distress and asphyxia of human ICP. We show that these neonates have elevated pulmonary bile acids that are associated with disrupted structure of pulmonary surfactant. Maternal absence of Nr1i2 superimposed upon Abcb11 deficiency strongly increased neonatal survival and is directly related to reduced maternal bile acid concentrations. The mechanism accounting for reduced serum bile acids in the mothers deficient in both Nr1i2 and Abcb11 appears related to disrupted reabsorption of intestinal bile acids due to changes in transporter expression. These findings provide novel insights into pulmonary failure by revealing bile acids capability to disrupt the structure of surfactant producing collapsed alveoli, pulmonary failure and ultimately death. These findings have important implications for neonatal health especially when maternal bile acids are elevated during pregnancy and highlight a potential pathway and targets amenable to therapeutic intervention to ameliorate this condition. We used microarrays to measure changes in gene expression profiles in lung tissues from Abcb11+/- lungs after interbreeding C57BL/6 wild-type female or C57BL/6 Abcb11-/- female mice against either C57BL/6 wild-type male mice or C57BL/6 Abcb11-/- male mice to create only heterozygote offspring. We also measured profiles in liver tissues from age-matched C57BL/6 wild-type and C57BL/6 Abcb11-/- mice. Lung tissues were collected from day E17.5, E18.5 and neonatal (N0) mice. Liver tissues were collected from 1.5-month-old C57BL/6 wildtype and Abcb11-/- mice.

Project description:Disruption of circadian rhythm during pregnancy produced adverse health outcomes in offspring. However, the role of maternal circadian rhythms in infants’ immunity and their susceptibility to inflammation remains poorly understood. Here we reported that disruption of circadian rhythms in pregnant mice profoundly aggravated the severity of neonatal inflammatory disorders, including necrotizing enterocolitis (NEC) and sepsis. The diminished production of maternal-derived docosahexaenoic acid (DHA) and the impaired immunosuppressive function of myeloid-derived suppressor cells (MDSCs) in neonates played a dominant role in this process. Mechanistically, DHA enhanced the immunosuppressive function of neonatal MDSCs viaPPARγ mediated mitochondrial oxidative phosphorylation. Transfer of MDSCs or perinatal supplementation of DHA relieved neonatal inflammation induced by maternal rhythms disruption. These observations revealed an important role of maternal circadian rhythms in the control of neonatal inflammation via metabolic reprograming of myeloid cells.

Project description:Gene expression profiling was performed on CNS tissue from neonatal mice carrying the T9H translocation and maternal or paternal duplication of proximal Chromosomes 7 and 15. Our analysis revealed the presence of two novel paternally expressed intergenic transcripts at the PWS/AS locus. The transcripts were termed Pec2 and Pec3 for paternally expressed in the CNS.Our analysis also revealed imprinting of Magel2, Mkrn3, Ndn,Ube3a and Usp29, as well as Pec2 and Pec3 in embryonic brain, 15.5 dpc, and provided a survery of biallelically expressed genes on proximal Chromosomes 7 and 15 in embryonic and neonatal CNS. This SuperSeries is composed of the following subset Series:; GSE12227: Neonatal and embyronic CNS of mice with maternal or paternal duplication of proximal chromosomes 7 and 15 (430A); GSE12230: Neonatal and embyronic CNS of mice with maternal or paternal duplication of proximal chromosomes 7 and 15 (430B) Experiment Overall Design: Refer to individual Series

Project description:Feed additives aiming to improve gastrointestinal health are frequently supplied to piglets after weaning but might be more effective when administered before weaning. In this period, feed additives can either be administered directly to neonates, or indirectly via sow’s feed. It is yet unknown what the effect of the administration route is on gut functionality and health. Therefore, we compared the effect of different dietary interventions on gut functionality after maternal administration (lactation feed) to the neonatal administration route (oral gavage). These feed interventions included medium chain fatty acids (MCFA), beta-glucans (BG), and galacto-oligosaccharides (GOS). We measured intestinal gene expression and microbiota composition after birth (d1) and after weaning (d31). Our results show that the type of intervention and the administration route influence gut functionality (microbiome and gene expression profiles). MCFA administration led to a more differentially orchestrated response when comparing the neonatal and maternal administration route then the other two additives, indicating the route of administration of the feed interventions is determinative for the outcome. This implies that for each nutritional intervention in early life of a pig the optimal route of administration needs to be determined.
