Project description:The purpose of this study was to determine the difference of the miRNA profiles between normal and preeclamptic placenta. Ten placental samples were analyzed. Six were from preeclamptic patients and four were from normal pregnancies.
Project description:Plasma from normal and preeclamptic pregnancies was collected and added in the culture medium of HUVEC cells. The aims are double: identifying putative biomarkers that could be modified recurrently in the endothelium under preeclampsia and understand at term the molecular bases of the increased risk of cardiovascular and kidney diseases in woman that have had a preeclampsia. 2 pools of 3 control plasmas and 2 pools of 4 preeclamptic plasma were organized and added at a concentration of 1/10 on HUVEC cells, during 24 hours before transcriptomic analysis

Project description:Genome wide DNA methylation profiling of normal and preeclampsia placental samples. Illumina Infinium HumanMethylation450 BeadChip (450K array) was used to obtain DNA methylation profiles in placental samples. Samples included 16 samples from healthy uncomplicated pregnancies and 8 samples from pregnancies affected by preeclampsia.
Project description:Plasma from pregnant women were applied three days in three steps to HUVEC cells. RNAs were isolated and prepared. Four pools of RNAs were obtained, two of them from cells exposed to preeclamptic plasma (2 and 3, corresponding to mild and severe preeclampsia, respectively) and two from cells exposed to normal plasma from pregnant women (five and five).
Project description:Abstract Objective: To investigate the physiology of ectopic pregnancy by analyzing the miRNA profiles of the pregnancy tissue from both ectopic and control pregnancies (voluntary termination of pregnancy). Design: Research study. Setting: Academic research institute in collaboration with a university hospital. Patients: Patients suffering from tubal EP and patients with a normal ongoing pregnancy scheduled for a voluntary termination of pregnancy (VTOP) were recruited. Interventions: Pregnancy tissue samples were analyzed by miRNA microarray and further validated by qPCR. Main Outcome measures: Gene expression profiles and quantitative PCR measurements. Results: Four miRNAs were found to be downregulated in EP compared to healthy trophoblast tissue, and three miRNAs were upregulated in EP trophoblast compared to control tissue samples. All genes were validated by q-PCR. We found three statistically significant miRNAs, all of which were upregulated in the EP sample group. Conclusion: We describe the alteration of seven miRNAs in EP samples that could alter pathways which are critical for correct implantation such as extracellular matrix (ECM) remodeling, or mucin biosynthesis, thus resulting in ectopic pregnancies.
