Lee YJ, Kim J, Kwon YH. Long-Term Effects of Maternal Fat Consumption on the Brain Transcriptome of Obesogenic Diet-Fed Young Adult Mice Offspring. J Nutr 2024:S0022-3166(24)00159-7. [PMID: 38484978 DOI: 10.1016/j.tjnut.2024.03.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 02/17/2024] [Accepted: 03/11/2024] [Indexed: 04/07/2024] Open
Abstract
BACKGROUND Substantial evidence has demonstrated that maternal high-fat (HF) consumption during gestation and lactation plays as a risk factor for neurodevelopmental alterations and subsequent neurological disorders. OBJECTIVE We investigated the regulatory mechanisms of maternal fat consumption on brain development and function in offspring at different ages. METHODS Mouse dams were fed either a control diet [low-fat (LF)] or an HF diet for 3 wk before mating and throughout pregnancy and lactation. Offspring were killed at postnatal day (PD) 21 (LF21 and HF21), and the rest were fed an HF diet for 12 wk until the killing at PD 105 (LF105 and HF105). The expression levels of genes and proteins in the brains of offspring were analyzed by microarray and immunoblotting, respectively. RESULTS Maternal dietary fat content, offspring age, and their interaction affected the expression levels of 1215, 10,453, and 2105 genes, respectively. The 67 differentially expressed genes (DEGs) between the HF21 and LF21 groups were enriched in several Gene Ontology terms related to nervous system development. Among 45 DEGs of the HF105/LF105 comparison, several genes associated with neurotransmitter action are detected. In addition, we observed increased activation of the AMP-dependent protein kinase-cAMP response element binding protein signaling pathway in HF105/LF105 comparison. However, maternal fat content did not change the protein levels of amyloid-β and tau hyperphosphorylation, the markers of neuropathogenesis. CONCLUSIONS Maternal HF feeding altered the expression of genes involved in the development and neurotransmitter system in the brains of PD 21 and HF diet-fed PD 105 offspring, respectively. Especially, the absence of overlap between DEGs at each comparison highlights the dynamic nature of alterations in gene expression in offspring of dams fed an HF diet. Further investigation on older adult offspring is necessary to elucidate the effects of maternal fat intake on the brain pathophysiology of offspring.

A Study of the Literature on Intrauterine Treatment Options for Chronic Placental Insufficiency with Intrauterine Growth Restriction Using Intrauterine Intravascular Amino Acid Supplementation. Life (Basel) 2023; 13:1232. [PMID: 37374014 DOI: 10.3390/life13061232] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 05/10/2023] [Accepted: 05/12/2023] [Indexed: 06/29/2023] Open
Abstract
BACKGROUND Intrauterine growth retardation (IUGR) is a very serious prenatal condition with 3-5% incidence of all pregnancies. It results from numerous factors, including chronic placental insufficiency. IUGR is associated with an increased risk of mortality and morbidity and is considered a major cause of fetal mortality. Currently, treatment options are significantly limited and often result in preterm delivery. Postpartum, IUGR infants also have higher risks of disease and neurological abnormalities. METHODS The PubMed database was searched using the keywords "IUGR", "fetal growth restriction", "treatment", "management" and "placental insufficiency" for the period between 1975 and 2023. These terms were also combined together. RESULTS There were 4160 papers, reviews and articles dealing with the topic of IUGR. In total, only 15 papers directly dealt with a prepartum therapy of IUGR; 10 of these were based on an animal model. Overall, the main focus was on maternal intravenous therapy with amino acids or intraamniotic infusion. Treatment methods have been tested since the 1970s to supplement the fetuses with nutrients lacking due to chronic placental insufficiency in various ways. In some studies, pregnant women were implanted with a subcutaneous intravascular perinatal port system, thus infusing the fetuses with a continuous amino acid solution. Prolongation of pregnancy was achieved, as well as improvement in fetal growth. However, insufficient benefit was observed in infusion with commercial amino acid solution in fetuses below 28 weeks' gestation. The authors attribute this primarily to the enormous variation in amino acid concentrations of the commercially available solutions compared with those observed in the plasma of preterm infants. These different concentrations are particularly important because differences in the fetal brain caused by metabolic changes have been demonstrated in the rabbit model. Several brain metabolites and amino acids were significantly decreased in IUGR brain tissue samples, resulting in abnormal neurodevelopment with decreased brain volume. DISCUSSION There are currently only a few studies and case reports with correspondingly low case numbers. Most of the studies refer to prenatal treatment by supplementation of amino acids and nutrients to prolong pregnancy and support fetal growth. However, there is no infusion solution that matches the amino acid concentrations found in fetal plasma. The commercially available solutions have mismatched amino acid concentrations and have not shown sufficient benefit in fetuses below 28 weeks' gestation. More treatment avenues need to be explored and existing ones improved to better treat multifactorial IUGR fetuses.

Abstract
Intrauterine Growth Restriction (IUGR) hinders the correct growth of the fetus during pregnancy due to the lack of oxygen or nutrients. The developing fetus gives priority to brain development ("brain sparing"), but the risk exists of neurological and cognitive deficits at short or long term. On the other hand, diets rich in fat exert pernicious effects on brain function. Using a pig model of spontaneous IUGR, we have studied the effect on the adult of a long-term high-fat diet (HFD) on the neurotransmitter profile in several brain areas, and the morphology and the proteome of the hippocampus. Our hypothesis was that animals affected by IUGR (born with low birth weight) would present a different susceptibility to an HFD when they become adults, compared with normal birth-weight animals. Our results indicate that HFD affected the serotoninergic pathway, but it did not provoke relevant changes in the morphology of the hippocampus. Finally, the proteomic analysis revealed that, in some instances, NBW and LBW individuals respond to HFD in different ways. In particular, NBW animals presented changes in oxidative phosphorylation and the extracellular matrix, whereas LBW animals presented differences in RNA splicing, anterograde and retrograde transport and the mTOR pathway.

Abstract
Supplementation of a mother’s diet with antioxidants such as hydroxytyrosol (HTX) has been proposed to ameliorate the adverse phenotypes of foetuses affected by intrauterine growth restriction (IUGR). Our previous studies showed, in a porcine model of IUGR, an effect of maternal HTX supplementation on the neurotransmitter profile of several brain areas and the morphology of the hippocampus in 100 days old foetuses. The present study analyzed the impact of maternal HTX supplementation on the hippocampus proteome at this foetal age by TMT10plex labelling. Eleven differentially abundant proteins were identified by comparing both conditions, and eight of them downregulated and three upregulated in the HTX-treated group. The downregulated proteins were mainly involved in protein synthesis and RNA metabolism and may explain the differences in neuron differentiation in the HTX-treated group. The upregulated proteins were related to cell detoxification and could represent a potential mechanism to explain the neuroprotective effect of HTX.

Abstract
Supplementation of a mother’s diet with antioxidants, such as hydroxytyrosol (HTX), has been proposed to ameliorate the adverse phenotypes of fetuses at risk of intrauterine growth restriction. In the present study, sows were treated daily with or without 1.5 mg of HTX per kilogram of feed from day 35 of pregnancy (at 30% of total gestational period), and individuals were sampled at three different ages: 100-day-old fetuses and 1-month- and 6-month-old piglets. After euthanasia, the brain was removed and the hippocampus, amygdala, and prefrontal cortex were dissected. The profile of the catecholaminergic and serotoninergic neurotransmitters (NTs) was characterized and an immunohistochemical study of the hippocampus was performed. The results indicated that maternal supplementation with HTX during pregnancy affected the NT profile in a brain-area-dependant mode and it modified the process of neuron differentiation in the hippocampal CA1 and GD areas, indicating that cell differentiation occurred more rapidly in the HTX group. These effects were specific to the fetal period, concomitantly with HTX maternal supplementation, since no major differences remained between the control and treated groups in 1-month- and 6-month-old pigs.

Abstract
OBJECTIVE To investigate fetal epicardial fat thickness (EFT) value in fetal growth restriction (FGR) and its relationship with clinical parameters, fetal modified myocardial index (Mod-MPI), and the Doppler parameters. MATERIAL METHODS Eighty-five pregnant women, with 30 diagnosed with FGR and 55 healthy pregnant women as control group participated in this prospective case-control study. FGR group was divided into 2 subgroups as early (n = 9) and late FGR (n = 21) groups. Demographic data were taken from the medical records. Amnion fluid value, fetal biometric measurements, and Doppler parameters were obtained. Fetal EFT and fetal Mod-MPI were measured by using the echocardiographic methods. The correlation tests were performed to assess the association between EFT and clinical and ultrasonographic parameters. p < .05 was interpreted as statistically significant. RESULTS EFT value was found statistically lower in the early and late FGR groups than the control group (p = .003). Higher umbilical artery pulsatility index (PI) and lower cerebroplacental ratio (CPR) values were found in the early and late FGR (p < .001, p = .001). The optimal EFT cutoff level to predict FGR disease was measured as 1.25 with 63.3% specificity and 77.4% sensitivity. Lower ejection time (ET) and higher Mod-MPI and isovolumetric contraction time (ICT) values were found in the group FGR with absent UAEDF than in the group FGR with no absent UAEDF (p = .001, p < .000, p < .000, respectively). Correlation tests showed statistically negative and weak correlations among EFT, umbilical artery PI, and mean Ut A-PI (p = .019, p = .019). Positive correlations were found in regard to gestational age, EFW, and EFT (p = .002, p < .000). CONCLUSION Our study showed that the measurement of EFT may contribute to predicting the diagnosis of FGR. Moreover, lower EFT values can be related to the severity of FGR. Future randomized control studies are needed to understand the effects and pathways of fetal EFT on fetal cardiac function.

Abstract
SIGNIFICANCE We determined decreases in choroidal thickness and retinal nerve fiber layer (RNFL) thickness in all quadrants. Our findings show that the choroid and RNFL are affected before the emergence of ocular symptoms in malnourished children. PURPOSE We aimed to determine whether the RNFL, a component of the neuronal structure, and the choroid, supplying the retina, are affected in children with malnutrition using spectral-domain optical coherence tomography. METHODS One hundred twenty-six malnourished patients without ocular symptoms, aged between 5 and 10 years, and 116 healthy children were included in the study. Age, sex, weight-for-age (WFA) z score, height-for-age z score, body mass index-for-age z score, and spectral-domain optical coherence tomography data were recorded. RESULTS Average RNFL thickness was 96.5 μm (82.0 to 128.0 μm) in the malnutrition group and 111.0 μm (95.0 to 128.0 μm) in the control group (P < .001). Retinal nerve fiber layer thickness was statistically significantly lower in all quadrants in malnourished patients compared with the control group. Median choroidal thickness in the foveal center was 304.0 μm (250.0 to 375.0 μm) in the malnutrition group and 345.0 μm (280.0 to 403.0 μm) in the control group (P < .001). Choroidal thickness in all quadrants was also statistically significantly lower in malnourished patients. Positive correlation was determined between average RNFL thicknesses and WFA z score. Average RNFL thickness decreased as WFA z score decreased (r = 0.730 and P < .001). Positive correlation was also observed between choroidal thickness in the foveal center and WFA z score. Foveal center choroidal thickness decreased in line with WFA z score (r = 0.786 and P < .001). CONCLUSIONS Our results show that the retinal nerve fiber layer and choroidal thickness decreased in malnourished children without clinically reported ocular symptoms. A decreased retinal nerve fiber layer and choroidal thickness may be an important clue to the prevention of retinal pathologies that may develop at later ages if the malnutrition is not addressed.

Abstract
In the first case, the AA and glucose were infused through a perinatal port system into the umbilical vein at 30 weeks' gestation due to severe IUGR. The patient received daily hyperbaric oxygenation (HBO, 100% O2) with 1.4 atmospheres absolute for 50 min for 7 days. At 31+4 weeks' gestation, the patient gave birth spontaneously to a newborn weighing 1378 g, pH 7.33, APGAR score 4/6/intubation. In follow‐up examinations at 5 years of age, the boy was doing well without any neurological disturbance or developmental delay. In the second case, the patient presented at 25/5 weeks' gestation suffering from severe IUGR received HBO and maternal AA infusions. The cardiotocography was monitored continuously during HBO treatment. The short‐time variations improved during HBO from 2.9 to 9 msec. The patient developed pathologic CTG and uterine contractions 1 day later and gave birth to a hypotrophic newborn weighing 420 g. After initial adequate stabilization, the extremely preterm newborn unfortunately died 6 days later. Fetal nutrition combined with HBO is technically possible and may allow the prolongation of the pregnancy. Fetal‐specific amino‐acid composition would facilitate the treatment options of IUGR fetuses and extremely preterm newborn.

Abstract
Objectives: Placental steroid metabolism is linked to the fetal hypothalamus-pituitary-adrenal axis. Intrauterine growth restriction (IUGR) might alter this cross-talk and lead to maternal stress, in turn contributing to the pathogenesis of anxiety-related disorders of the offspring, which might be mediated by fetal overexposure to, or a reduced local enzymatic protection against maternal glucocorticoids. So far, direct evidence of altered levels of circulating/local glucocorticoids is scarce. Liquid chromatography tandem-mass spectrometry (LC-MS/MS) allows quantitative endocrine assessment of blood and tissue. Using a rat model of maternal protein restriction (low protein [LP] vs. normal protein [NP]) to induce IUGR, we analyzed fetal and maternal steroid levels via LC-MS/MS along with the local expression of 11beta-hydroxysteroid-dehydrogenase (Hsd11b). Methods: Pregnant Wistar dams were fed a low protein (8%, LP; IUGR) or an isocaloric normal protein diet (17%, NP; controls). At E18.5, the expression of Hsd11b1 and 2 was determined by RT-PCR in fetal placenta and brain. Steroid profiling of maternal and fetal whole blood, fetal brain, and placenta was performed via LC-MS/MS. Results: In animals with LP-induced reduced body (p < 0.001) and placental weights (p < 0.05) we did not observe any difference in the expressional Hsd11b1/2-ratio in brain or placenta. Moreover, LP diet did not alter corticosterone (Cort) or 11-dehydrocorticosterone (DH-Cort) levels in dams, while fetal whole blood levels of Cort were significantly lower in the LP group (p < 0.001) and concomitantly in LP brain (p = 0.003) and LP placenta (p = 0.002). Maternal and fetal progesterone levels (whole blood and tissue) were not influenced by LP diet. Conclusion: Various rat models of intrauterine stress show profound alterations in placental Hsd11b2 gatekeeper function and fetal overexposure to corticosterone. In contrast, LP diet in our model induced IUGR without altering maternal steroid levels or placental enzymatic glucocorticoid barrier function. In fact, IUGR offspring showed significantly reduced levels of circulating and local corticosterone. Thus, our LP model might not represent a genuine model of intrauterine stress. Hypothetically, the observed changes might reflect a fetal attempt to maintain anabolic conditions in the light of protein restriction to sustain regular brain development. This may contribute to fetal origins of later neurodevelopmental sequelae.

Abstract
Balancing self-renewal with differentiation is crucial for neural stem cells (NSC) functions to ensure tissue development and homeostasis. Over the last years, multiple studies have highlighted the coupling of either metabolic or epigenetic reprogramming to NSC fate decisions. Metabolites are essential as they provide the energy and building blocks for proper cell function. Moreover, metabolites can also function as substrates and/or cofactors for epigenetic modifiers. It is becoming more evident that metabolic alterations and epigenetics rewiring are highly intertwined; however, their relation regarding determining NSC fate is not well understood. In this review, we summarize the major metabolic pathways and epigenetic modifications that play a role in NSC. We then focus on the notion that nutrients availability can function as a switch to modify the epigenetic machinery and drive NSC sequential differentiation during embryonic neurogenesis.

Abstract
PURPOSE Intrauterine growth restriction (IUGR) has been shown to induce the programming of metabolic disturbances and obesity, associated with hypothalamic derangements. The present study aimed at investigating the effects of IUGR on the protein and metabolite profiles of the hypothalamus of adult female rats. METHODS Wistar rats were mated and either had ad libitum access to food (control group) or received only 50% of the control intake (restricted group) during the whole pregnancy. Both groups ate ad libitum throughout lactation. At 4 months of age, the control and restricted female offspring was euthanized for blood and tissues collection. The hypothalami were processed for data independent acquisition mass spectrometry-based proteomics or targeted mass spectrometry-based metabolomics. RESULTS The adult females submitted to IUGR showed increased glycemia and body adiposity, with normal body weight and food intake. IUGR modulated significantly 28 hypothalamic proteins and 7 hypothalamic metabolites. The effects of IUGR on hypothalamic proteins and metabolites included downregulation of glutamine synthetase, glutamate decarboxylase, glutamate dehydrogenase, isocitrate dehydrogenase, α-ketoglutarate, and up-regulation of NADH dehydrogenase and phosphoenolpyruvate. Integrated pathway analysis indicated that IUGR affected GABAergic synapse, glutamate metabolism, and TCA cycle, highly interconnected pathways whose derangement has potentially multiple consequences. CONCLUSION The present findings suggested that the effects of IUGR on GABA/glutamate-glutamine cycle may be involved in the programming of obesity and hyperglycemia in female rats.

Abstract
Hyperemesis gravidarum (HG) is characterized by severe gestational nausea and vomiting, leading to dehydration, electrolyte imbalance and nutritional deficits. HG adversely affects the health and wellbeing of the woman. However, the detrimental impact of HG on fetal brain development has not been addressed. We evaluate herein the emerging evidence suggesting that HG interferes with human brain development, and discuss putative mechanisms. Evidence emerges from prospective developmental studies in offspring exposed in utero to HG, from studies of pregnancy outcome after in utero exposure to famine, as well as evidence on specific nutritional deficiencies affecting fetal brain development.

Cardiac and placental mitochondrial characterization in a rabbit model of intrauterine growth restriction. Biochim Biophys Acta Gen Subj 2018; 1862:1157-1167.

Abstract
BACKGROUND Intrauterine growth restriction (IUGR) is associated with cardiovascular remodeling persisting into adulthood. Mitochondrial bioenergetics, essential for embryonic development and cardiovascular function, are regulated by nuclear effectors as sirtuins. A rabbit model of IUGR and cardiovascular remodeling was generated, in which heart mitochondrial alterations were observed by microscopic and transcriptomic analysis. We aimed to evaluate if such alterations are translated at a functional mitochondrial level to establish the etiopathology and potential therapeutic targets for this obstetric complication. METHODS Hearts and placentas from 16 IUGR-offspring and 14 controls were included to characterize mitochondrial function. RESULTS Enzymatic activities of complexes II, IV and II + III in IUGR-hearts (-11.96 ± 3.16%; -15.58 ± 5.32%; -14.73 ± 4.37%; p < 0.05) and II and II + III in IUGR-placentas (-17.22 ± 3.46%; p < 0.005 and -29.64 ± 4.43%; p < 0.001) significantly decreased. This was accompanied by a not significant reduction in CI-stimulated oxygen consumption and significantly decreased complex II SDHB subunit expression in placenta (-44.12 ± 5.88%; p < 0.001). Levels of mitochondrial content, Coenzyme Q and cellular ATP were conserved. Lipid peroxidation significantly decreased in IUGR-hearts (-39.02 ± 4.35%; p < 0.001), but not significantly increased in IUGR-placentas. Sirtuin3 protein expression significantly increased in IUGR-hearts (84.21 ± 31.58%; p < 0.05) despite conserved anti-oxidant SOD2 protein expression and activity in both tissues. CONCLUSIONS IUGR is associated with cardiac and placental mitochondrial CII dysfunction. Up-regulated expression of Sirtuin3 may explain attenuation of cardiac oxidative damage and preserved ATP levels under CII deficiency. GENERAL SIGNIFICANCE These findings may allow the design of dietary interventions to modulate Sirtuin3 expression and consequent regulation of mitochondrial imbalance associated with IUGR and derived cardiovascular remodeling.

Abstract
OBJECTIVE To investigate the effect of aspirin on fetal weight in fetuses with idiopathic asymmetrical intrauterine growth restriction (IUGR) complicated by abnormal umbilical artery Doppler indices. MATERIALS AND METHODS The study was a randomized controlled trial conducted at Woman's Health Hospital, Assiut, Egypt, between June 2016 and the January 2017 included 60 pregnant women (28-30 weeks) with idiopathic asymmetrical IUGR associated with abnormal umbilical artery Doppler indices. Women were randomly assigned to group I (aspirin 75 mg) daily for four weeks or group II (no intervention). The primary outcome was the fetal weight after four weeks. Secondary outcomes included Doppler blood flow changes in the umbilical artery plus delivery and neonatal outcomes. RESULTS The estimated fetal weight and umbilical artery blood flow increased significantly in aspirin group (p = .00) when compared with no intervention group. As regard neonatal outcomes; aspirin group showed better results and encouraging outcomes (p < .05). CONCLUSIONS Aspirin improves fetal weight and umbilical artery blood flow in idiopathic asymmetrical IUGR fetuses complicated by abnormal umbilical artery Doppler blood flow.
