(Submitter supplied) Pre-eclampsia is one of the most serious pregnancy-associated disorders, and is defined by hypertension (systolic blood pressure higher than 140mmHg or diastolic blood pressure higher than 90mmHg) with proteinuria (more than 0.3g/day). It is not a simple complication of pregnancy, but is rather a syndrome of multiple organ failure involving the liver, kidney, and lung, as well as coagulatory and neural systems. more...

(Submitter supplied) d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. more...

(Submitter supplied) We investigated the DNA methylation and gene expression of 20 chorionic villi samples from early onset preeclampsia placentas to 20 gestational age matched controls. From this we were able to see a widespread disregulation in DNA methylation across a subset of genes in the genome. This may help to elucidate the underlying biological problems that lead to early onset preeclampsia. We noted that there were DNA methylation changes in many genes of importance as well as in different genomic elements such as enhancers.

(Submitter supplied) 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.

(Submitter supplied) Maternal smoking has a severe negative effect on all stages of pregnancy that in consequence impairs fetal growth and development. Tobacco smoke-related defects are well established at the clinical level; however, little is known about molecular mechanisms underlying these pathological conditions. We thus employed a genomic approach to determine transcriptome alterations induced by maternal smoking in pregnancy. more...

(Submitter supplied) Background: Early-onset preeclampsia (EOPE) and late-onset preeclampsia (LOPE) has been regarded as two different phenotypes with heterogeneous manifestation. The underlying mechanisms remain elusive. Aim to gain insight into the pathogenesis of the two traits, we analyzed the placental gene expression profiles in preeclampsia placentas. Methods: Whole genome-wide microarray was used to describe the gene expression profiles in the placenta tissues from patients with early-(n=7; <34 weeks), late-onset(n=8; >36 weeks) PE and their controls who delivered preterm (n=5;<34 weeks) or at term(n=5; >36 weeks) Genes were selected as differentially expressed upon a fold-change≥2 and q-value<0.05. more...

(Submitter supplied) Human epidemiological evidence has led scientists to theorize that undernutrition during gestation is an important early origin of adult diseases. Animal models have successfully demonstrated that maternal diet could contribute to some of adult diseases. Undernutrition is perceived harmful in pregnant women whereas calorie restriction is a strategy proven to extend healthy and maximum life span in adult. more...
