(Submitter supplied) Obesity during pregnancy is related to adverse maternal and neonatal outcomes. Factors involved in these outcomes may include increased maternal insulin resistance, inflammation, oxidative stress and nutrient mishandling. The placenta is the primary determinant of fetal outcomes, and its function can be impacted by maternal obesity. The aim of this study in mice was to determine the effect of obesity on maternal lipid handling, inflammatory and redox state, and placental oxidative stress, inflammatory signalling, and gene expression relative to female and male fetal growth. more...

(Submitter supplied) Obesity during pregnancy is associated with fetal growth restriction in the offspring. We used RNA next generation sequencing analysis (HiSeq2000) to have a snapshot of the placenta transcriptome at embryonic day 19 to examine whether mice exposed to maternal obesity had significant changes in their transcriptome which may lead to growth restriction in the fetus.

(Submitter supplied) Sexual dimorphism in placental physiology during development affects the functionality of placental adaptation during adverse pregnancy, affecting fetal growth, development, and eventually fetal programming, which have long-term effects on the offspring’s adult life. However, studies focusing on the phenomenon and relationship between sex-specific placental adaptation and consequent altered fetal development are still elusive. more...

(Submitter supplied) Here, we describe the use of high-throughput sequencing to examine the developmental basis of placental growth defects observed in the male offspring of alcohol-exposed fathers. We exposed C57BL/6J male mice to 10% ethanol for ten weeks, then bred them to naïve CD-1 dams. The male offspring of ethanol-exposed sires exhibited placental growth defects. We isolated total RNA from four F1 male placentae from each control and ethanol preconception treatment and conducted deep-sequencing analysis of the transcriptome. more...

(Submitter supplied) Maternal obesity during pregnancy leads to a pro-inflammatory milieu in the placenta. We conducted a global transcriptomic profiling in BeWo cells following palmitic acid (PA, 500 uM) and/or TNF-alpha (10 ng/ml) treatment for 24 h. Microarray analysis revealed that placental cytotrophoblasts increased expression of genes related to inflammation, stress response and immediate-early factors in response to plamitic acid, TNF-alpha or a combination of both. more...
