Project description:Through a series of mouse genetic studies, we concluded that miR-26 overexpression in intestinal epithelial cells inhibits tumor formation in Apcmin/+ mice. We isolated intestinal epithelial cells from M2rtTA and M2rtTA; eGFP.miR-26a to assess gene expression changes after the induction of miR-26a expression. Intestinal epithelial cells were isolated from three M2rtTA and three M2rtTA; eGFP.miR-26a mice after treatment with doxycycline for 10 days. Gene expression was profiled using Illumina microarrays.

Project description:Intra-uterine growth restriction (IUGR) and fetal overgrowth increase the risk of postnatal health. Maternal nutrition is the major intrauterine environmental factor that alters fetal weight. However, the mechanisms underlying maternal nutrition affect fetal development is not entirely clear. We developed a pig model and used isobaric tags for relative and absolute quantification (iTRAQ) to investigate alterations in the placental proteome were obtained from gilts in normal-energy-intake (Con) and high-energy-intake (HE) group, respectively.At 90 d of gestation, the heavy fetuses were found at the tubal ends and light fetuses at the cervical ends of the uterus in Con group and the heavy fetuses had higher glucose concentration than the light fetuses. However, a higher uniformity was noted in HE group. Placental promote between these two positions indicated that a total of 78 and 50 differentially expressed proteins were detected in Con and HE group, respectively. In Con group, these proteins related to lipid metabolism (HADHA, AACS, CAD), nutrient transport (GLUT, SLC27A1) and energy metabolism (NDUFV1, NDUFV2, ATP5C1). However, the differentially expressed proteins in HE group were mainly participation in transcriptional and translational regulation and intracellular vesicular transport.

Project description:In cattle, harnessing information from the maternal blood to predict fetal health and development is attractive yet scarcely explored. We hypothesised that variations in fetal growth at the end of the organogenesis period impact on the molecular profile of fetal organs and is reflected in the maternal blood transcriptome. The objectives were to determine the transcriptomic modifications in maternal blood and in fetal liver, gonads, and heart according to fetal weight and to model a molecular signature based on the fetal organs allowing the prediction of fetal weight from the maternal blood transcriptome. In addition to a contemporaneous maternal blood sample, organ samples were collected from 10 male fetuses at day 42 day of gestation for RNA-sequencing. Fetal weight ranged from 1.25 to 1.69 gr (mean 1.44 ± 0.15 gr). Data were analysed through co-expression cluster analysis to identify biologically relevant genes dynamically changing according to fetal weight in each fetal organ and in maternal blood. Results revealed clusters of genes, the expression of which was positively correlated with fetal weight, and which enriched ontological terms involved in the organ functionality. For the heart, the 1346 co-expressed genes were involved in energy generation and protein synthesis. For the gonads, the 1042 co-expressed genes enriched seminiferous tubule development. The 459 co-expressed genes identified in the liver were associated with lipid synthesis and metabolism. Finally, the cluster of 571 co-expressed genes determined in maternal blood enriched oxidative phosphorylation and thermogenesis. The expression patterns of the common genes between the clusters in each fetal organ and the cluster in maternal blood were employed to construct a predictive regression model of fetal weight. The data from the fetal organs were used to train the model, and the data from the maternal blood were used to test it. The best prediction was achieved when the model was trained with the 35 common genes between heart and maternal blood (root mean square error=0.04, R-square=0.93). In conclusion, linking transcriptomic information from maternal blood with that from the fetal heart unveils maternal blood as a sensor of fetal development.

Project description:The discovery of fetal mRNA transcripts in maternal circulation holds great promise for noninvasive prenatal diagnosis. To identify potential fetal biomarkers, we studied whole blood and plasma transcripts common to term pregnant women and their newborns but reduced or absent in the postpartum mothers. In whole blood, 157 potentially-fetal transcripts were identified. RT-PCR confirmed the presence of specific transcripts, SNP analysis confirmed the presence of fetal transcripts in maternal circulation. Comparison of whole blood and plasma samples from the same women suggested that placental genes are more easily detected in plasma. We conclude that fetal and placental mRNA circulates in the blood of pregnant women.

[I] We profiled whole antepartum (A), postpartum (P), and umbilical cord (U) blood samples from each of 9 mothers and their 10 newborns (1 set of twins, denoted as a and b after the sample names). [II] We also profiled plasma samples (A, P, and U) from three of those mothers to allow for a direct comparison between blood and plasma.

Project description:Human mesenchymal stem cells circulate in 1st and early 2nd trimester fetal blood, but not in adults. Like other fetal cell types they cross the placenta, and can be found in maternal organs decades later. To determine potential ligands in human fetal mesenchymal stem cells not present in maternal blood, the gene expression of 1st trimester human fetal bone marrow, liver and blood derived mesenchymal stem cells will be compared to blood mononuclear cells from pregnant women using a Affymetrix human gene array system.

Project description:Maternal and fetal monocytes and tissue macrophages (decidual macrophages, Hofbauer cells) at the feto-maternal interface have different methylome. Paired and balanced design. We compared maternal blood monocytes (MB) vs. cord blood monocytes (CB), maternal blood monocytes (MB) vs. decidual macrophages (Deci), cord blood monocytes (CB) vs placental macrophages (villi) and decidual macrophages (Deci) vs. placental macrophages (villi).

Project description:Maternal obesity in mice negatively affects placental functionand maternal and fetal liver function. We performed a global proteomic analysis using a liquid-chromatography/mass-spectrometry system to investigate total and phosphorylated proteins in the placenta and fetal liver in a mouse model that combines maternal obesity with maternal androgen excess to identify changes in molecular pathways that might promote diseases in adulthood.
