Maternal nutrition modulates fetal development through inducing placental efficiency changes in gilts

ABSTRACT: Intra-uterine growth restriction (IUGR) and fetal overgrowth increase the risk of postnatal health. Maternal nutrition is the major intrauterine environmental factor that alters fetal weight. However, the mechanisms underlying maternal nutrition affect fetal development is not entirely clear. We developed a pig model and used isobaric tags for relative and absolute quantification (iTRAQ) to investigate alterations in the placental proteome were obtained from gilts in normal-energy-intake (Con) and high-energy-intake (HE) group, respectively.At 90 d of gestation, the heavy fetuses were found at the tubal ends and light fetuses at the cervical ends of the uterus in Con group and the heavy fetuses had higher glucose concentration than the light fetuses. However, a higher uniformity was noted in HE group. Placental promote between these two positions indicated that a total of 78 and 50 differentially expressed proteins were detected in Con and HE group, respectively. In Con group, these proteins related to lipid metabolism (HADHA, AACS, CAD), nutrient transport (GLUT, SLC27A1) and energy metabolism (NDUFV1, NDUFV2, ATP5C1). However, the differentially expressed proteins in HE group were mainly participation in transcriptional and translational regulation and intracellular vesicular transport.

<h4>Background</h4>Intra-uterine growth restriction (IUGR) and fetal overgrowth increase risks to postnatal health. Maternal nutrition is the major intrauterine environmental factor that alters fetal weight. However, the mechanisms underlying the effects of maternal nutrition on fetal development are not entirely clear. We developed a pig model, and using isobaric tags for relative and absolute quantification (iTRAQ), we investigated alterations in the placental proteome of gilts on a normal-ene ...[more]

Project description:Compairsion of transcriptional profiles of heart and skeletal muscle tissue of fetal rhesus monkey exposed to maternal Bisphenol A or vehicle during early or late gestaion. Maternal exposure to the endocrine disrupting chemical, bisphenol A (BPA) affects the development of multiple organ systems in rodents and monkeys. However, effects of BPA exposure on cardiac and skeletal muscle development have not been assessed. Given that maternal BPA crosses placenta and reaches developing fetus, examining the physiological consequences of gestational exposure during development is of research significance. Therefore, we evaluate the effects of daily, oral BPA exposure of pregnant rhesus monkeys (Macaca mulatta) on the fetal heart and skeletal muscle transcriptome. Pregnant monkeys were administered daily oral doses (400 M-BM-5g/kg body weight) of BPA during early (50 M-bM-^@M-^S100 M-BM-1 2 days post conception, dpc) or late (100 M-BM-1 2 dpc - term), gestation. At the end of treatment, fetal heart tissues; left ventricle (LV), right ventricle (RV), left atrium (LA), right atrium (RA) and skeletal muscle; biceps femoris (BFM), were collected. Transcriptome expression was assessed using genome-wide microarray in each of the tissues and compared paired-wise between the BPA and matched control fetuses. Our results show that maternal BPA exposure alters transcriptional profile of several coding and non-coding genes in fetal heart and skeletal muscle. Pregnant rhesus monkey were administered a daily oral dose of 400 M-NM-<g/kg. body weight of Bisphenol A (BPA) or vehicle (CON) either during early (50M-bM-^@M-^S100 M-BM-1 2 days) or late (100 M-BM-1 2 daysM-bM-^@M-^Sterm) gestation. Gene expression profiles of each of the heart chambers (left ventricle, LV; right ventricle, RV; left atrium, LA; and right atrium, RA) and skeletal muscle (biceps femoris, BFM) were analyzed using microarrays and compared between the BPA exposed and matched control fetuses. A total of 12 samples were analyzed for each tissue; LV, RV, LA, RA and BFM. This includes 6 samples at each time period (early vs. late gestation) and 3 biological replicates for each treatment (BPA, n=3; control, n=3).
