MetabolomicsEffect of Genetically Reduced Maternal Myostatin on Late Gestation Maternal, Fetal, and Placental Metabolomes in Mice.
Myostatin (gene symbol: Mstn) is an autocrine and paracrine inhibitor of muscle growth. Pregnant mice with genetically reduced levels of myostatin give birth to offspring with greater adult muscle mass and bone biomechanical strength. However, maternal myostatin is not detectable in fetal cir...

MetabolomicsSexual dimorphism in the fetal cardiac response to maternal nutrient restriction
Poor maternal nutrition causes intrauterine growth restriction (IUGR); however, its effects on fetal cardiac development are unclear. We have developed a baboon model of moderate maternal undernutrition, leading to IUGR. We hypothesized that the IUGR affects fetal cardiac structure and metabolism. S...

MetabolomicsPregnancy-Induced Metabolic Phenotype Variations in Maternal Plasma
Metabolic variations occur during normal pregnancy to provide the growing fetus with a supply of nutrients required for its development and to ensure the health of the woman during gestation. Mass spectrometry-based metabolomics was employed to study the metabolic phenotype variations in the materna...

MetabolomicsMaternal Gut Microbiota Influences Immune Activation at the Maternal-Fetal Interface Affecting Pregnancy Outcome

Preeclampsia is a leading cause of morbidity and mortality in pregnant women, affecting 5-8% of gestations worldwide. Its development is influenced by maternal immune abnormalities, metabolic disorders and gut dysbiosis. In this study, we show that gut dysbiosis in pregnant C57BL/6J dams leads to...

MetabolomicsFaecalibaculum rodentium as a key player in combating maternal obesity-induced labor disorders

The global rise in maternal obesity increases the risk of adverse maternal and neonatal outcomes. This study demonstrates that both long- (12 weeks) and short-term (gestational) exposure to a high-fat diet (HFD) induces uterine labor disorders, elevates stillbirth rates, and alters gut microbiota...

MetabolomicsComparative characterization of the infant gut microbiome and their maternal lineage by a multi-omics approach

The human gut microbiome establishes and matures during infancy, and dysregulation at this stage may lead to pathologies later in life. We conducted a multi-omics study comprising three generations of family members to investigate the early development of the gut microbiota. Fecal samples from 20...

MetabolomicsMaternal steroids during pregnancy and their associations with ambient air pollution and temperature during preconception and early gestational periods
Hormones play critical roles in facilitating pregnancy progression and the onset of parturition. Several classes of environmental contaminants, including fine particulate matter (PM2.5) and ambient temperature, have been shown to alter hormone biosynthesis or activity. However, epidemiolo...

MetabolomicsMaternal MASLD rewires milk bile-acid hydrophobicity to restrict microbiome-dependent neonatal ketone supply_hippocampus
Maternal metabolic dysfunction-associated steatotic liver disease (MASLD) in mice creates a paradoxical neonatal ketone deficit during nursing, despite preserved hepatic ketogenesis, that precedes adult spatial memory impairment. Vulnerable litters show reduced β-hydroxybutyrate (β-HB) in the intest...

MetabolomicsMaternal plasma metabolomic profiling of periparturient dairy cows supplemented with high-dose chromium propionate before calving
This study contains untargeted LC-MS/MS metabolomic profiles of maternal plasma collected on the day of calving from Holstein dairy cows in the control and high-dose chromium propionate supplementation groups. Cows received either a basal total mixed ration without supplemental chromium propionate o...

MetabolomicsMaternal regulation of biliary disease in neonates via gut microbial metabolites

Maternal seeding of the microbiome in neonates promotes a long-lasting biological footprint, but how it impacts disease susceptibility in early life remains unknown. We hypothesized that feeding butyrate to pregnant mice influences the newborn’s susceptibility to biliary atresia, a severe cholang...
