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...

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...

MetabolomicsMetabolic profiling of maternal serum of women at high-risk of spontaneous preterm birth using NMR and MGWAS approach
Preterm birth (PTB) is a leading global cause of infant mortality. Risk factors include genetics, lifestyle choices and infection. Understanding the mechanism of PTB could aid the development of novel approaches to prevent PTB. This study aimed to investigate the metabolic biomarkers of PTB in early...

TranscriptomicsGene expression changes in the septum: possible implications for microRNAs in sculpting the maternal brain.
The transition from the non-maternal to the maternal state is characterized by a variety of CNS alterations that support the care of offspring. The septum (including lateral and medial portions) is a brain region previously linked to various emotional and motivational processes, including maternal c...

TranscriptomicsRNA-seq of estrogen (E2) induced changes of mRNA expression in early pregnant Sus scrofa endometrium
Maternal exposure to estrogens can induce long-term adverse effects in the offspring. This may be mediated through alterations in the endometrium affecting embryo-maternal communication as early as the preimplantational phase. Thus, we analyzed the effects of gestational estradiol-17β (E2) exposure ...

MetabolomicsLimited vertical transmission but profound immune dysregulation at the maternal-fetal interface after SARS-CoV-2 infection

The endemic of SARS-CoV-2 underscores the imperative to elucidate its effects on pregnancy, particularly regarding the potential for vertical transmission and its influence on the early maternal-fetal interface, which remain insufficiently defined. To address this, we performed an extensive cohor...

TranscriptomicsIdentification of differentially methylated regions between placentas and maternal blood cells on chromosome 18
Comparison of DNA methylation levels of chromosome 18 between placentas and blood cells of pregnant women Extracted DNA from 5 cases of placental tissues and 5 cases of maternal blood cell was subjected to MeDIP (methylated DNA immunoprecipitation) and hybridized to Affymetrix GeneChip® Human Tiling...

MetabolomicsGut Microbiota Mediates Maternal PM2.5 Exposure-induced Neurodevelopmental Disorder in offspring via Disturbing the Glutamate Metabolism: Evidence from Multiomics Analysis

While accumulating evidence links maternal PM2.5 exposure to offspring neurodevelopmental impairments, yet the underlying biological pathways require further elucidation. To address this, female ICR mice are exposed to filtered air (FA) or concentrated ambient particulate matter (CAP) for three ...

TranscriptomicsMaternal MicroRNAs are Essential for Mouse Zygotic Development
MicroRNAs (miRNAs) have been shown to have important functions in a variety of cellular processes. Here we report on miRNA expression and their dynamic regulation during mouse oogenesis and early embryos. We show that following specific deletion of Dicer from growing oocytes, the mutant oocytes ceas...

TranscriptomicsInvolvement of the brain renin-angiotensin system in the effects of maternal separation
The postnatal development of the mouse is characterized by a stress hyporesponsive period (SHRP), where basal corticosterone levels are low and responsiveness to mild stressors is reduced. Maternal separation is able to disrupt the SHRP and is widely used to model early trauma. In this study we aime...
