Project description:To determine differential expression of microRNAs in placentae with severe pre-eclampsia and normal placenta. Differential expression of microRNAs in placentae (4 severe pre-eclampsia and 4 normal control) was screened by microarray platform, then some differential microRNAs were selected and validated with real-time quantitative reverse transcription polymerase chain reaction in placentae of severe pre-eclampsia (n=24) and normal control group (n=26). Results: We validated the expression of some microRNAs altered in the microarray, and found the following microRNAs were significantly increased in severe pre-eclampsia placentae: miR-16, miR-29b, miR-195, miR-26b, miR-181a, miR-335 and miR-222. Conclusion: These differential microRNAs may play an important role in pathogenesis of pre-eclampsia.

We analyzed the microRNA expression in the placentae of Chinese patients with severe pre-eclampsia.

Project description:Genome-wide analysis of decidual transcriptome in pre-eclampsia compared with normotensive controls to find differentially expressed genes/pathways. Preeclampsia (PE) is a common and serious pregnancy hypertensive disorder with a strong genetic component. The study aims were to use genome-wide analysis of decidual transcriptome in pre-eclampsia compared with normotensive controls to identify differentially expressed biological pathways, and to determine common pathways between the transcriptome and previously identified maternal susceptibility genes.

Project description:Hypertensive disorders in pregnancy, of which the multisystem pathology pre-eclampsia is most severe, often lead to preterm delivery, maternal mortality and life-long complications. Pre-eclampsia lacks early screening tools and causal therapies, illustrating the urgent need for a better understanding of early disease dynamics. Here, we present the first study comparing single-nuclei transcriptomes of human diseased preterm preeclamptic placentae and healthy controls, embedding the characterization of the maternal-fetal barrier dysfunction in the context of a comprehensive spatio-temporal study including early and late gestational placentae. Our results highlight and contextualize a perturbed communication from fetal to maternal side during the development of pre-eclampsia starting with a dysregulated trophoblast stem-cell maturation. We provide new targets for potential early disease prevention in order to protect mother and child from increased gestational mortality and morbidity but also from life-long increased cardiovascular disease risk.

Project description:It has been well documented that pre-eclampsia and unexplained fetal growth restriction (FGR) has a common etiological background, but little is known about the linkage al the molecular level. we have performed global gene expression profiling by oligonucleotide microarrays for placentas from pre-eclamptic, unexplained FGR and normal pregnancies to further elucidate the mechanisms underlying the development of these two disorders. The total number of samples used was 8 from pre-eclampsia, 8 from normotensive pregnancies with FGR and 8 from those without FGR.

Project description:DNA from four 29 cases, 38 tumor samples (23 PB, 12 LN, 1 Tonsil, 1 colonic biopsy, 1 spleen) and 29 normal DNA from the same patients were analyzed with Affymetrix SNP 6.0 platform for copy number alterations study. Affymetrix SNP arrays were performed according to the manufacturer's directions on DNA extracted from blood samples, lymph nodes and other tissues like spleen, tonsil and colonic biopsy
