Maternal nutrition is one of the major determinants of pregnancy outcome. It has been suggested that reduced intakes or lack of specific nutrients during pregnancy influences the length of gestation, proper placental and fetal growth during pregnancy. Maternal nutrition, particularly micronutrients such as folate and vitamin B12, and long-chain polyunsaturated fatty acids (LCPUFA) are the major determinants of the one carbon cycle and are suggested to be at the heart of intrauterine programming of diseases in adult life...

BACKGROUND: Maternal overweight and obesity during pregnancy is associated with insulin resistance, hyperglycaemia, hyperlipidaemia and a low-grade state of chronic inflammation. The aim of this pre-specified analysis of secondary outcome measures was to evaluate the effect of providing antenatal dietary and lifestyle advice on cardiometabolic and inflammatory biomarkers. METHODS: We conducted a multicentre trial in which pregnant women who were overweight or obese were randomised to receive either Lifestyle Advice or Standard Care...

BACKGROUND: The study of lipid metabolism in stem cell physiology has recently raised great interest. The role of lipids goes beyond the mere structural involvement in assembling extra- and intra-cellular compartments. Nevertheless, we are still far from understanding the impact of membrane lipidomics in stemness maintenance and differentiation patterns. In the last years, it has been reported how in vitro cell culturing can modify membrane lipidomics. The aim of the present work was to study the membrane fatty acid profile of mesenchymal stromal cells (MSCs) derived from human fetal membranes (hFM-MSCs) and to correlate this to specific biological properties by using chemically defined tailored lipid supplements (Refeed®)...

OBJECTIVE: To investigate if the role of Cav-1 in GDM-induced macrosomia is through regulating AMPK signaling pathway in placenta. METHODS: We used diagnostic criteria of gestational diabetes mellitus (GDM) and macrosomia to separate and compare placental protein and mRNA levels from GDM with macrosomia group (GDMM), GDM with normal birth weight group (GDMN) and normal glucose tolerance (NGT) with normal birth weight group (CON). Western blotting was performed to examine differentially expressed proteins of caveolin-1 (Cav-1) and Adenosine monophosphate-activated protein kinase (AMPK) signaling pathway related proteins, including phosphorylated-AMPKα(Thr172), AMPKα, phosphorylated-Acetyl-CoA carboxylase(Ser79) (p-ACC(Ser79)), ACC and glucose transporter 1 (GLUT1) in placenta between the three groups...

Trans fatty acid may impair fetal growth and infant neurodevelopment, but the quantity in a placenta and human tissues remains unknown. To address the issue, a simple and reliable method of quantification is needed. We established a method of quantifying trans-octadecenoic acids (trans-6,8,9,11 18:1 fatty acids, TOAs), a major component of TFA, in human tissue samples, and then determined the TOAs level in the placenta. Oleic acid (OA) (C18:1(9c)) was measured by isotope dilution gas-chromatography mass-spectrometry, and the TOAs level was subsequently calculated based on the ratio of the peak areas for TOAs and OA (TOAs/OA) in the mass chromatogram...

Metabolic disorders usually increase the level of reactive oxygen species (ROS) and damage mitochondrial function. The placenta supplies nutrients and hormonal signals to the fetus for regulating fetal metabolism, and is also prone to injury by oxidants. The aim of this study was to determine the effect of pre-existing maternal type 2 diabetes mellitus (DM) combined with obesity on placental mitochondrial function and metabolism disorders of offspring. The study included 96 pregnant women. The women were put into the following groups: healthy women (control, n=24), women with DM (DM, n=24), women with obesity (OB, n=24) and women with both DM and obesity (DM+OB, n=24)...

BACKGROUND: Gestational diabetes mellitus (GDM) is associated with increased fetal adiposity, which may increase the risk of obesity in adulthood. The placenta has insulin receptors and maternal insulin can activate its signaling pathways, affecting the transport of nutrients to the fetus. However, the effects of diet or insulin treatment on the placental pathophysiology of GDM are unknown. SUMMARY: There are very few studies on possible defects in the insulin signaling pathway in the GDM placenta...

BACKGROUND: Oxidative damage present in obese/overweight mothers may lead to further oxidative stress conditions or inflammation in maternal and cord blood samples. Thirty-four pregnant women/newborn pairs were included in this study to assess the presence of oxidative stress biomarkers and their relationship with serum cytokine concentrations. Oxidative stress biomarkers and antioxidant enzymes were compared between the mother/offspring pairs. The presence of 27 cytokines was measured in maternal and cord blood samples...

High fructose consumption in the Western diet correlates with disease states such as obesity and metabolic syndrome complications, including type II diabetes, chronic kidney disease, and non-alcoholic fatty acid liver disease. Liver and kidneys are responsible for metabolism of 40-60% of ingested fructose, while the physiological fate of the remaining fructose remains poorly understood. The primary metabolic pathway for fructose includes the fructose-transporting solute-like carrier transport proteins 2a (SLC2a or GLUT), including GLUT5 and GLUT9, ketohexokinase (KHK), and aldolase...

Low weight at birth associates with subsequent susceptibility to diabetes. Epigenetic modulation is among the mechanisms potentially mediating this association. We performed a genome-wide DNA methylation analysis in placentas from term infants born appropriate-for-gestational-age (AGA) or small-for-gestational-age (SGA), to identify new genes related to fetal growth and neonatal body composition. Candidate genes were validated by bisulfite pyrosequencing (30 AGA, 21 SGA) and also analyzed in cord blood. Gene expression analyses were performed by RT-PCR...

Overweight during pregnancy predisposes both the mother and foetus to health complications. Maternal complications include gestational diabetes, obstetric problems and type 2 diabetes later in life. Complications for the offspring are not only restricted to the foetal period or birth, such as prematurity and foetal macrosomia, but may also have long-term metabolic health implications through the mechanism of early nutrition programming. One of the key metabolic components characterising overweight in the non-pregnant state is low-grade inflammation manifested by elevated levels of circulatory pro-inflammatory cytokines...

The factors determining fatty acid transfer across the placenta are not fully understood. This study used a combined experimental and computational modeling approach to explore placental transfer of nonesterified fatty acids and identify the rate-determining processes. Isolated perfused human placenta was used to study the uptake and transfer of (13)C-fatty acids and the release of endogenous fatty acids. Only 6.2 ± 0.8% of the maternal (13)C-fatty acids taken up by the placenta was delivered to the fetal circulation...

BACKGROUND: Abnormal fatty acid oxidation (FAO) is associated with maternal and fetal complications during pregnancy. The contribution of maternal and fetal tissues to FAO capacity during late pregnancy is important to understand the pathophysiology of pregnancy-associated complications. The aim of this study was to determine the expression levels of mitochondrial FAO enzymes in maternal and fetal tissues during late normal pregnancy. METHODS: We have measured by Real-time PCR the levels of long- and medium -chain acyl-CoA dehydrogenase (LCHAD and MCAD), two acyl-CoA dehydrogenases that catalyze the initial step in the mitochondrial FAO spiral...

Since it is known that placental overexpression of the human anti-angiogenic molecule sFlt-1, the main candidate in the progression of preeclampsia, lead to intrauterine growth restriction (IUGR) in mice by lentiviral transduction of mouse blastocysts, we hypothesize that sFlt-1 influence placental morphology and physiology resulting in fetal IUGR. We therefore examined the effect of sFlt-1 on placental morphology and physiology at embryonic day 18.5 with histologic and morphometric analyses, transcript analyses, immunoblotting, and methylation studies...

Changes in the maternal environment leading to an altered intrauterine milieu can result in subtle insults to the fetus, promoting increased lifetime disease risk and/or disease acceleration in childhood and later in life. Particularly worrisome is that the prevalence of NAFLD is rapidly increasing among children and adults, and is being diagnosed at increasingly younger ages, pointing towards an early-life origin. A wealth of evidence, in humans and non-human primates, suggests that maternal nutrition affects the placenta and fetal tissues, leading to persistent changes in hepatic metabolism, mitochondrial function, the intestinal microbiota, liver macrophage activation and susceptibility to NASH postnatally...

Over the past three decades, extensive research has been able to determine the biologic functions for the main bioactive sphingolipids, namely ceramide, sphingosine, and sphingosine 1-phosphate (S1P) (Hannun, 1996; Hannun et al., 1986; Okazaki et al., 1989). These studies have managed to define the metabolism, regulation, and function of these bioactive sphingolipids. This emerging body of literature has also implicated bioactive sphingolipids, particularly S1P and ceramide, as key regulators of cellular homeostasis...

Pregnancy represents a state of heightened oxidative stress and inflammation, and these processes are further increased in pregnancy complications. The quality of the maternal diet is directly associated with maternal health and wellbeing, pregnancy and fetal outcomes, as well as the risk of pregnancy complications. Long chain polyunsaturated fatty acids (LCPUFAs) have significant potential to modify placental and fetal lipid environments and thereby modulate health outcomes. The omega-3 (n-3) LCPUFA in particular have been shown to exhibit both antioxidant and anti-inflammatory properties, and have potential therapeutic applications in reducing oxidative damage and inflammation during pregnancy...

Inflammation and dysregulated lipid metabolism are involved in the pathogenesis of preeclampsia, and fatty acid binding protein 4 (FABP4) is known to regulate both inflammation and lipid metabolism. In the present study, we elucidated the role of FABP4 using in vitro and in vivo models of preclampsia. We found increased expression of FABP4 in the placenta of preeclamptic rats, which was further confirmed in HTR-8 cells, an extravillous trophoblast cell line, treated with L-NAME. Overexpression of FABP4 in HTR-8 cells resulted in upregulated expression of pro-inflammatory cytokines IL-6 and TNF-α, and increased lipid accumulation, suggesting that FABP4 plays a role in preeclampsia...
