Project description:Preeclampsia (PE) is a common pregnancy disorder, and it complicates 5~7% of all pregnancies. At present, termination of pregnancy is the only curative strategy for PE. To explore a potential target for PE treatment, we collected placental tissue samples from patients with preeclampsia (PE) and normal pregnant women (N), and performed high-throughput RNA sequencing. We found that FOXP2 was significantly downregulated in placental samples of patients with PE compared with the controls.

Project description:Normal pregnancy requires adaptations of the maternal vasculature. During preeclampsia these adjustments are not well established, resulting in maternal hypertension and proteinuria. The effects of preeclampsia on the maternal vasculature are not yet fully understood. We aimed to identify gene expression differences in the aorta between non pregnant, healthy pregnant, and experimental preeclamptic rats using a genome wide approach. Whole aortic tissue was isolated from rats with low-dose LPS-induced preeclampsia, healthy pregnant and non-pregnant rats. Gene expression was measured by a whole genome microarray.

Project description:The pathogenesis of preeclampsia superimposed on chronic hypertension is poorly understood relative to preeclampsia occurring in pregnant people without chronic hypertension. Placental transcriptomes in pregnancies complicated by de novo preeclampsia and superimposed preeclampsia have not been previously compared.

Project description:It has been proposed that two amino acid substitutions in the transcription factor FOXP2 have been positively selected during human evolution due to effects on aspects of speech and language. Here, we introduce these substitutions into the endogenous Foxp2 gene.of mice. Although these mice are generally healthy, they have qualitatively different ultrasonic vocalizations, decreased exploratory behavior and decreased dopamine concentrations in the brain suggesting an effect of the humanized Foxp2 allele on basal ganglia. In the striatum, a part of the basal ganglia that is affected in humans with a speech deficit due to one non-functional FOXP2 allele, we find that medium spiny neurons have increased dendrite lengths and increased synaptic plasticity. Since mice carrying one non-functional Foxp2 allele show opposite effects, this suggests that alterations in cortico-basal ganglia circuits might have been important for the evolution of speech and language in humans. In this particular experiment, we investigate the effects of human Foxp2 (Foxp2hum) and the non-functional Foxp2 allele on striatal gene expression in embryonic, young and adult mice. We determined genome-wide gene expression patterns in striatal biopsies from Foxp2hum/hum, Foxp2wt/ko and Foxp2wt/wt mice using high-density oligonucleotide arrays. The animals were derived from two independent FoxP2 knock-in strains and one knock-out strain. In total 71 animals were used, 29 males and 42 females. The mice ages were E16.5, P15, P18, P21 and P95 when sacrificed. The microarrays were processed in totally six batches.

Project description:We perform placental microRNA expression profiling to identify potential microRNAs involved in the development and pathogenesis of preeclampsia. microRNA expression profiling for serum was quantified by qPCR and evaluated at 12, 16, and 20 gestational weeks and at the time of preeclampsia diagnosis. Two groups were evaluated using TaqMan Low Density Array plates: a control group with 18 normotensive pregnant women and a preeclampsia group with 16 patients who developed preeclampsia during the follow-up period. The placental microRNA profile was assayed at delivery (7 cases and 7 controls) using the Illumina GAIIx sequencing platform.

Project description:Preeclampsia is a severe placenta-related pregnancy disorder that is generally divided into two subtypes named early-onset preeclampsia (onset <34 weeks of gestation), and lateonset preeclampsia (onset ≥34 weeks of gestation), with distinct pathophysiological origins. Both forms of preeclampsia have been associated with maternal systemic inflammation. However, alterations in the placental immune system have been less well characterized. Here, we studied immunological alterations in early- and late-onset preeclampsia placentas using a targeted expression profile approach. RNA was extracted from snap-frozen placenta samples (healthy n=13, early-onset preeclampsia n=13, and late-onset preeclampsia n=6). The expression of 730 immune-related genes from the Pan Cancer Immune Profiling Panel was measured, and the data were analyzed Q10 in the advanced analysis module of nSolver software (NanoString Technology). The results showed that early-onset preeclampsia placentas displayed reduced expression of complement, and toll-like receptor (TLR) associated genes, specifically TLR1 and TLR4. Mast cells and M2 macrophages were also decreased in early-onset preeclampsia compared to healthy pl acentas. The findings were confirmed by an immunohistochemistry approach using 20 healthy, 19 early-onset preeclampsia, and 10 late-onset preeclampsia placentas. We conclude that the placental innate immune system is altered in early-onset preeclampsia compared to uncomplicated pregnancies. The absence of these alterations in late-onset preeclampsia placentas indicates dissimilar immunological profiles. The study revealed distinct pathophysiological processes in earlyonset and late-onset preeclampsia placentas and imply that a tailored treatment to each subtype is desirable.

Project description:Maternal serum levels of calcyclin and heat shock protein 90 were compared throughout pregnancy from the first trimester till term among women with preeclampsia (PE) and age-matched normotensive pregnant controls (C). Serum samples from two different studies, a nested case-control study embedded in the Rotterdam periconception cohort and the Lepra Study both conducted at the Erasmus MC in Rotterdam. They were collected in the first, second and third trimester of pregnancy in 43 patients with preeclampsia, consisting of 20 early-onset and 23 late-onset preeclampsia, and 46 normotensive pregnant controls. A serum based 2D LC-MS assay on Parallel Reaction Monitoring mode using a high resolution tribrid mass spectrometer was used to quantify both calcyclin and heat shock protein 90.

Project description:Preeclampsia (PE) is a hypertensive pregnancy syndrome associated with target organ damage and higher cardiovascular sequelae and requires antihypertensive therapy. However, about 40% of patients are nonresponsive to treatment, leading to worse clinical outcomes. Through proteomics, we aimed to compare the circulating protein profiles and identify differentially expressed proteins of 10 responsive (R-PE) and 10 nonresponsive (NR-PE) patients to 10 healthy pregnant controls (HP). We performed plasma protein relative quantification using mass spectrometry.

Project description:During pregnancy, perfluorooctane sulfonate (PFOS) exposure is linked to increased risks of preeclampsia and fetal developmental complications. Although experimental and circumstantial data suggest that PFOS induces endothelial dysfunction, leading to decreased uterine arterial blood flow and gestational hypertension, the precise regulatory mechanisms responsible for this effect remain unknown. To address this issue, we treated human uterine artery endothelial cells (hUAECs) isolated from pregnant women with PFOS and conducted a comparative transcriptomic analyses to understand the underlying mechanism of PFOS-induced endothelial dysfunction.
