Project description:The tubal ectopic pregnancy (TEP) is a severe pregnancy complication accounted for 10-15% pregnancy-related deaths owing to the implantation and growth of embryos in fallopian tubes. Placental villi from TEP exhibit significant difference compared with that from intrauterine pregnancy (IP) in total volumes, trophoblast differentiation and intravillous vascularization. To investigate the difference in expression profiles of placental villi from IP and TEP, placental villi were collected from each phenotype, separated from maternal tissues and analyzed by high-throughput sequencing. generated a mouse model in which p53 is activated in neural crest cells due to the expression of a mutant p53 protein (p53-25,26) that can bind to and stabilize wild-type p53. Here, we performed gene expression profiling on neural crest cells isolated from these embryos, to identify the transcriptional response to p53 activation during embryogenesis.

Molecular expression in endometrial biopsies of non-viable ectopic and intrauterine pregnancies.

Project description:Ectopic pregnancy is the leading cause of morbidity and mortality among women in the first trimester. A reliable diagnostic test for the detection of ectopic pregnancy in cases of non-viable pregnancy of unknown location (NV-PUL) is needed. The objective of the current study is to prospectively validate our previous findings of a 12-cilia gene classifier for the identification of ectopic pregnancy. Molecular interrogation is performed to define differences in molecular expression profiles in ectopic and abnormal intrauterine pregnancies. These samples come from a prospective cohort study comparing transcriptome profiles from women with ectopic pregnancy (ECT) or non-viable intrauterine pregnancy (NV-IUP). Samples were analyzed with the Affymetrix Human Gene 2.0 ST Array.

Differences in molecular expression in cases of non-viable ectopic and intrauterine pregnancies

Project description:Ectopic pregnancy is the leading cause of morbidity and mortality among women in the first trimester. A reliable diagnostic test for the detection of ectopic pregnancy in cases of non-viable pregnancy of unknown location (NV-PUL) is needed. The objective of the current study is to define differences in molecular expression profiles in ectopic and abnormal intrauterine pregnancies toward discovery of biologically plausible ectopic classifier candidate. These samples come from a prospective cohort study comparing transcriptome profiles from women with ectopic pregnancy (ECT) or non-viable intrauterine pregnancy (NV-IUP).

Differential miRNA profiles of pregnancy tissue in ectopic pregnancies

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. This study was authorized by the Institutional Review Board/Independent Ethics Committee of the Hospital Universitario La Fe, Valencia, Spain. Eight patients suffering from tubal EP and another eight patients with a normal ongoing pregnancy scheduled for a VTOP were recruited.
