Project description:Growth restriction, craniofacial dysmorphology and central nervous system defects are the main diagnostic features of fetal alcohol syndrome. Studies in humans and mice have reported that the growth restriction can be prenatal and/or postnatal, but the underlying mechanisms remain unknown. We recently described a mouse model of moderate gestational ethanol exposure that produces measurable phenotypes in line with fetal alcohol syndrome, e.g. craniofacial changes and growth restriction in adolescent mice. Here we further characterize the growth restriction phenotype by measuring body weight at gestational day 16.5, cross-fostering from birth to weaning, and extending our observations into adulthood. Furthermore, in an attempt to unravel the molecular events contributing to the growth phenotype, we have compared gene expression patterns in the liver and kidney of non-fostered ethanol-exposed and control mice at postnatal day 28. We find that the ethanol-induced growth phenotype is not detectable prior to birth, but is present at weaning, even in mice that have been cross-fostered to unexposed dams. This suggests a postnatal growth restriction phenotype that is not due to deficient postpartum care by dams that drank ethanol, but rather a physiological result of ethanol exposure in utero. We also find that, despite some catch-up growth after five weeks of age, the effect extends into adulthood, consistent with longitudinal studies in humans. Genome-wide gene expression analysis revealed interesting ethanol-induced changes in the liver, including genes involved in the metabolism of exogenous and endogenous compounds, iron homeostasis and lipid metabolism. Gene expression changes in the livers of offspring exposed to alcohol in utero compared to controls.

Project description:Alcohol (ethanol, EtOH) consumption during pregnancy can result in fetal alcohol spectrum disorders (FASDs), which are characterized by prenatal and postnatal growth restriction and craniofacial dysmorphology. The specific mechanisms by which alcohol mediates these injuries have yet to be determined. Cell-derived extracellular vesicles, including exosomes and microvesicles containing several species of RNAs (exRNAs), have recently emerged as a mechanism of cell-to-cell communication. However, EtOH’s effects on the biogenesis and function of non-coding exRNAs during fetal development have not been explored. Therefore, we studied the effects of maternal EtOH exposure on the composition of exRNAs in the amniotic fluid (AF) using a rat fetal alcohol exposure (FAE) model. Timed pregnant Sprague Dawley rats received 0 or 2.5 g/kg of 20% EtOH by oral gavage on embryonic days 5, 8, 10, 12 and 15. Through RNA-Seq analysis we identified and verified AF exosomal miRNAs with differential expression levels specifically associated with maternal EtOH exposure.

Project description:Mouse model for Fetal Alcohol Syndrome. Embryos exposed to alcohol in controlled environment to assess teratogenic effects. Fetal Alcohol Syndrome (FAS) is a leading developmental disorder. To date, a holistic view of molecular gene changes is largely unexplored. Using microarray analysis of whole embryo mouse culture with strict-control over alcohol-level, we found, directly related alcohol-metabolism, a reduction of retinol binding protein 1(Rbp1), and a, de novo expression of aldehyde dehydrogenase 1B1 (ALDH1B1). Remarkably, four key hemopoiesis genes (glycophorin A, adducin 2, beta-2 microglobulin, and ceruloplasmin) became absent, and many histone variants genes were reduced. Hypothesis-driven informatics analysis and intersection analysis of two independent experiments indicated that the altered genes are involved in cell growth, hemopoiesis, histone modification, eye and heart development, and a collective reduction in expression of growth factor genes (Igf1, Efemp1, Tieg, and Edil3) and neural specification genes (neurogenin, Sox 5, bHLHb5). Down-regulated neural specification phenotypes further supported the above findings. Further more, the gene expression profile indicated distinct subgroups which overlapped with the teratogenesis of the open- and the closed-neural tubes known in FAS. In summary, our data reveal genes alteration with causal potential for dysmorpology (e.g. retinoic acid, neuronal specification, and neurotrophic factors, and epigenetics related histone genes) and those downstream responsive genes related to alcohol metabolism, and developmental teratogenesis. Experiment Overall Design: Comparison of whole embryo gene expression after exposure to ethanol for 46 hours. Note 2 independent experiments completed.

Project description:Intrauterine growth restriction (IUGR) impairs fetal growth and development, perturbs nutrient metabolism, and increases the risk of developing diseases in the postnatal life. However, the underlying mechanisms by which IUGR affects fetuses remain incompletely understood. Here, we applied high-throughput proteomics approach and biochemical analysis to investigate the impact of IUGR on fetal liver.
