Transcription profiling of mouse placenta at different developmental time points

ABSTRACT: We used full genome microarrays to profile the full lifetime of the mouse placenta from embryonic day 8.5 (e8.5), at the time of chorioallantoic fusion, until postnatal day 0 (P0). For these samples, at each stage the fetal placenta and maternal decidual tissues were dissected and profiled separately (See series 1). For this experiment (Series 2), placental and decidual timecourse samples were normalized and modeled with two undissected (including placental and decidual tissue) e17 placentas to allow for scaling of values for comparison to the undissected placenta samples used in the publicly available mouse GeneAtlas dataset Experiment Overall Design: Mouse placentas were obtained from timed pregnant female mice at each timepoint, and fetal tissues were used to confirm embryo staging. For all dissected samples, fetal placenta and maternal decidual tissues were dissected and pooled separately for each litter prior to RNA extraction and hybridization on Affymetrix microarrays.

Genomic evolution of the placenta using co-option and duplication and divergence.

Knox Kirstin K Baker Julie C JC

Genome research 20080313 5

The invention of the placenta facilitated the evolution of mammals. How the placenta evolved from the simple structure observed in birds and reptiles into the complex organ that sustains human life is one of the great mysteries of evolution. By using a timecourse microarray analysis including the entire lifetime of the placenta, we uncover molecular and genomic changes that underlie placentation and find that two distinct evolutionary mechanisms were utilized during placental evolution in mice a ...[more]

Transcription profiling of mouse placental labyrinth and human villus tree

Project description:An important question for the use of the mouse as a model for studying human disease is the degree of functional conservation of genetic control pathways from human to mouse. The human placenta and mouse placenta show structural similarities but there has been no systematic attempt to assess their molecular similarities or differences. We built a comprehensive database of protein and microarray data for the highly vascular exchange region micro-dissected from the human and mouse placenta near-term. Abnormalities in this region are associated with two of the most common and serious complications of human pregnancy, maternal preeclampsia (PE) and fetal intrauterine growth restriction (IUGR), each disorder affecting ~5% of all pregnancies. To compare the gene expression patterns in the vascular exchange regions of the human (villus tree) and mouse (labyrinth) placenta. Experiment Overall Design: Mouse labyrinth tissue was micro-dissected form naturally mated crosses of C57Bl/6J mice. Placentas were individually dissected on embryonic day 17.5. From each litter ¼ of the tissue were set aside for RNA extraction and microarray analysis and ¾ for cellular fractionation and proteomic analysis, as recently described (Kislinger et al., 2006). Human villous trees were dissected from term normal placenta delivered by cesarean section from a term pregnancy (~ 38 weeks). Tissue was divided for organellar fractionation and RNA extraction.

O-GlcNAcome analysis in human placenta

Project description:In this study, we expand on this major advancement in O-GlcNAc enrichment protocols by adapting this approach to human-banked samples, which often presents their significant challenges. Indeed, patient samples are often banked without proper washing, thus contaminating cells with abundant O-glycosylated blood protein. These glycoproteins, such as human serum albumin, antibodies, and hemoglobin, pollute MS acquisition, masking the less abundant intracellular proteins and, even more, their O-GlcNAcylated forms. Thus, using freshly banked placentas, we present an adapted method to prepare human placental samples with naturally high blood content (13). We then enriched for O-GlcNAcylated protein using the PTMscan antibodies previously mentioned (12). However, our adapted protocol yielded over 60% of HexNAc peptide on total peptides. Per sample, we obtained up to 2,600 HexNAc-containing PSMs, 1,090 unique HexNAc peptides, and more than 1,000 unique HexNAc proteins using 45mg of starting placenta. Furthermore, we present a bioinformatic workflow to sort these HexNAc PSMs and extract the most confident O-GlcNAcylated proteins and sites. Thus, we confidentially identified 641 O-GlcNAcylated proteins, including up to 146 new proteins and 730 new sites within the 2 placental samples analyzed. Furthermore, we enriched for over 50 placenta-enriched O-GlcNAcylated proteins, such as RPA4, representing a new biomarker of the placental O-GlcNAcylation.

Integrated proteomics reveals apoptosis-related mechanisms associated with past-chronic stage of placental malaria

Project description:Malaria in pregnancy remains a substantial public health concern in malaria-endemic areas. Accumulation of maternal immune cells in the placenta and increased levels of inflammatory cytokines caused by sequestration of Plasmodium falciparum-infected erythrocytes (IE) in the placental intervillous blood spaces have been associated to poor neonatal outcomes, including low birth weight due to fetal growth restriction. However, little is known about the molecular changes occurring in the placenta in past-stages of P. falciparum infection when the hemozoin pigment is present in the absence of parasites. We conducted an integrated proteome, phosphoproteome and glycoproteome analysis in P. falciparum infected and non-infected placentas aiming to find molecular changes occurring in past-stage infection. A total of 2946 proteins, 1733 glycosites and 4100 phosphosites were identified and quantified in this study, disclosing overrepresented processes related to oxidative stress, protein folding and regulation of apoptosis, as well as AKT and ERK signaling pathways activation, which together with clinical data and literature-based information were further correlated to an increased apoptosis in infected placentas. This study showed apoptosis-related mechanisms associated with past-stage of malaria infection that can be further explored as therapeutic target against adverse pregnancy outcomes in placental malaria.

Transcriptomic effects of human STOX1B overexpression on the mouse placenta

Project description:STOX1B, the short protein-coding isoform of STOX1 (227 amino acids), has been shown to present opposite effects than the one of STOX1B in trophoblast cell models. Here, we investigate the overexpression of STOX1B in vivo in the mouse placenta. The changes accompany maternal effects on blood pressure and proteinuria reminiscent of preeclampsia, and effects of Intra Uterine Growth Restriction upon the foetuses.

Curing Preeclampsia induced by STOX1A expression in Mouse Placentas by Dietary Tetrahydrobiopterin Treatment

Project description:STOX1A overexpression in mice placenta triggers a preeclamptic phenotype in the mothers, with hypertension, proteinuria and kidney alterations (Doridot et al, Hypertension, 2013), this being connected with NO depletion and increase of nutrosative stress (Doridot et al, Antiox Redox Signal, 2014). Tetrahydrobiopterin (BH4) is a cofactor essential for NO production. We treated preeclamptic mice with this drug, and analyzed placental gene expression in four groups (Control mice, Control mice with BH4, Preeclamptic mice and preeclamptic mice with BH4).

Organ-specific gene expression changes in the fetal liver and placenta in response to maternal folate depletion

Project description:Growing evidence supports the hypothesis that the in utero environment can have profound implications for fetal development and for offspring health in later life. Current theory suggests that conditions experienced in utero prepare, or ‘programme’, the fetus for its anticipated post-natal environment. The mechanisms responsible for these programming events are poorly understood but are likely to involve gene expression changes. Folate is essential for normal fetal development and inadequate maternal folate supply during pregnancy has long term adverse effects on the offspring. We tested the hypothesis that inadequate folate supply during pregnancy alters offspring programming through altered gene expression. Female C57BL/6J mice were fed diets containing 2 mg folic acid/kg or 0.4 mg folic acid/kg for 4 weeks before mating and throughout pregnancy. At 17.5 day gestation, genome-wide gene expression in fetal liver and placenta of male offspring was measured by microarray analysis. In the fetal liver, 989 genes (555 up-regulated, 434 down-regulated) were expressed differentially in response to maternal folate depletion, with 460 genes expressed differentially (250 up-regulated, 255 down-regulated) in the placenta. Only 25 differentially expressed genes were common between organs, revealing that maternal folate intake during pregnancy influences fetal gene expression in a highly organ specific manner which, we propose, reflects prioritised protection of essential organ-specific functions.
