Abstract
Nonalcoholic fatty liver disease (NAFLD) is the main liver disease worldwide, and its prevalence in children and adolescents has been increasing in the past years. It has been demonstrated that parental exposure to different conditions, both preconceptionally and during pregnancy, can lead to fetal programming of several metabolic diseases, including NAFLD. In this article, we review some of the maternal and paternal conditions that may be involved in early-life programing of adult NAFLD. First, we describe the maternal nutritional factors that have been suggested to increase the risk of NAFLD in the offspring, such as an obesogenic diet, overweight/obesity, and altered lipogenesis. Second, we review the association of certain vitamin supplementation and the use of some drugs during pregnancy, for instance, glucocorticoids, with a higher risk of NAFLD. Furthermore, we discuss the evidence showing that maternal-fetal pathologies, including gestational diabetes mellitus (GDM), insulin resistance (IR), and intrauterine growth restriction (IUGR), as well as the exposure to environmental contaminants, and the impact of microbiome changes, are important factors in early-life programming of NAFLD. Finally, we review how paternal preconceptional conditions, such as exercise and diet (particularly obesogenic diets), may impact fetal growth and liver function. Altogether, the presented evidence supports the hypothesis that both in utero exposure and parental conditions may influence fetal outcomes, including the development of NAFLD in early life and adulthood. The study of these conditions is crucial to better understand the diverse mechanisms involved in NAFLD, as well as for defining new preventive strategies for this disease.

Liver disease in obesity and underweight: the two sides of the coin. A narrative review. Eat Weight Disord 2021; 26:2097-2107.

Abstract
PURPOSE Malnutrition, whether characterized by not enough or too much nutrient intake, is detrimental to the liver. We herein provide a narrative literature revision relative to hepatic disease occurrence in over or undernourished subjects, to shed light on the paradox where both sides of malnutrition lead to similar liver dysfunction and fat accumulation. METHODS Medline, EMBASE, and Cochrane Library were searched for publications up to July 2020. Articles discussing the association between both chronic and acute liver pathology and malnutrition were evaluated together with studies reporting the dietary intake in subjects affected by malnutrition. RESULTS The association between overnutrition and non-alcoholic fatty liver disease (NAFLD) is well recognized, as the beneficial effects of calorie restriction and very low carbohydrate diets. Conversely, the link between undernutrition and liver injury is more complex and less understood. In developing countries, early exposure to nutrient deficiency leads to marasmus and kwashiorkor, accompanied by fatty liver, whereas in developed countries anorexia nervosa is a more common form of undernutrition, associated with liver injury. Weight gain in undernutrition is associated with liver function improvement, whereas no study on the impact of macronutrient distribution is available. We hypothesized a role for very low carbohydrate diets in the management of undernutrition derived liver pathology, in addition to the established one in overnutrition-related NAFLD. CONCLUSIONS Further studies are warranted to update the knowledge regarding undernutrition-related liver disease, and a specific interest should be paid to macronutrient distribution both in the context of refeeding and relative to its role in the development of hepatic complications of anorexia nervosa. LEVEL OF EVIDENCE Narrative review, Level V.

Abstract
Maternal cardiovascular disease (CVD) during pregnancy is on the rise worldwide, as both more women with congenital heart disease are reaching childbearing age, and conditions such as diabetes, hypertension, and obesity are becoming more prevalent. However, the extent to which maternal CVD influences offspring health, as a neonate and later in childhood and adolescence, remains to be fully understood. The thrifty phenotype hypothesis, by which a fetus adapts to maternal and placental changes to survive a nutrient-starved environment, may provide an answer to the mechanism of maternal CVD and its impact on the offspring. In this narrative review, we aim to provide a review of the literature pertaining to the impact of maternal cardiovascular and hypertensive disease on the health of neonates, children, and adolescents. This review demonstrates that maternal CVD leads to higher rates of complications among neonates. Ultimately, our review supports the hypothesis that maternal CVD leads to intrauterine growth restriction (IUGR), which, through the thrifty phenotype hypothesis and vascular remodelling, can have health repercussions, including an impact on CVD risk, both in the immediate newborn period as well as later throughout the life of the offspring. Further research remains crucial in elucidating the mechanism of maternal CVD long-term effects on offspring, as further understanding could lead to preventive measures to optimise offspring health, including modifiable lifestyle changes. Potential treatments for this at-risk offspring group could mitigate risk, but further studies to provide evidence are needed.

Abstract
An increased susceptibility to non-alcoholic fatty liver disease (NAFLD) in female rat offspring that experienced prenatal ethanol exposure (PEE) has been previously demonstrated. The present study further investigated the potential mechanism. Based on the results from both fetal and adult studies of offspring rats that experienced PEE (4 g/kg/day), the fetal weight, serum glucose and triglyceride levels decreased significantly and hepatocellular ultra-structure was altered. Fetal livers exhibited inhibited expression and activity of sirtuin 1 (SIRT1), enhanced expression of lipogenic genes: sterol regulatory element binding protein 1c (SREBP1c), fatty acid synthase (FASN), acetyl-coenzyme A carboxylase α (ACCα), stearyl-coenzyme A desaturase 1 (SCD1). In adult offspring fed with high-fat diet, the PEE offspring revealed obviously catch-up growth, increased food intake, elevated serum metabolic phenotypes, suppressed hepatic SIRT1-SREBP1c pathway, and formation of NAFLD. Resveratrol (the chemical activator of SIRT1) could remarkably reverse the serum metabolic phenotypes and alleviate the hepatocyte steatosis in relation to the PEE offspring through activating the hepatic SIRT1-SREBP1c pathway. Therefore, increased susceptibility to diet-induced NAFLD in PEE offspring appears to be mediated by intrauterine programming of hepatic lipogenesis via the SIRT1-SREBP1c pathway. This altered programming effect could partially be reversed by resveratrol intervention after birth in PEE offspring rats.

Abstract
The rates of gestational cannabis use have increased despite limited evidence for its safety in fetal life. Recent animal studies demonstrate that prenatal exposure to Δ9-tetrahydrocannabinol (Δ9-THC, the psychoactive component of cannabis) promotes intrauterine growth restriction (IUGR), culminating in postnatal metabolic deficits. Given IUGR is associated with impaired hepatic function, we hypothesized that Δ9-THC offspring would exhibit hepatic dyslipidemia. Pregnant Wistar rat dams received daily injections of vehicular control or 3 mg/kg Δ9-THC i.p. from embryonic day (E) 6.5 through E22. Exposure to Δ9-THC decreased the liver to body weight ratio at birth, followed by catch-up growth by three weeks of age. At six months, Δ9-THC-exposed male offspring exhibited increased visceral adiposity and higher hepatic triglycerides. This was instigated by augmented expression of enzymes involved in triglyceride synthesis (ACCα, SCD, FABP1, and DGAT2) at three weeks. Furthermore, the expression of hepatic DGAT1/DGAT2 was sustained at six months, concomitant with mitochondrial dysfunction (i.e., elevated p66shc) and oxidative stress. Interestingly, decreases in miR-203a-3p and miR-29a/b/c, both implicated in dyslipidemia, were also observed in these Δ9-THC-exposed offspring. Collectively, these findings indicate that prenatal Δ9-THC exposure results in long-term dyslipidemia associated with enhanced hepatic lipogenesis. This is attributed by mitochondrial dysfunction and epigenetic mechanisms.

Abstract
Intrauterine growth restriction (IUGR) of the fetus, resulting from placental insufficiency (PI), is characterized by low fetal oxygen and nutrient concentrations that stunt growth rates of metabolic organs. Numerous animal models of IUGR recapitulate pathophysiological conditions found in human fetuses with IUGR. These models provide insight into metabolic dysfunction in skeletal muscle and liver. For example, cellular energy production and metabolic rate are decreased in the skeletal muscle and liver of IUGR fetuses. These metabolic adaptations demonstrate that fundamental processes in mitochondria, such as substrate utilization and oxidative phosphorylation, are tempered in response to low oxygen and nutrient availability. As a central metabolic organelle, mitochondria coordinate cellular metabolism by coupling oxygen consumption to substrate utilization in concert with tissue energy demand and accretion. In IUGR fetuses, reducing mitochondrial metabolic capacity in response to nutrient restriction is advantageous to ensure fetal survival. If permanent, however, these adaptations may predispose IUGR fetuses toward metabolic diseases throughout life. Furthermore, these mitochondrial defects may underscore developmental programming that results in the sequela of metabolic pathologies. In this review, we examine how reduced nutrient availability in IUGR fetuses impacts skeletal muscle and liver substrate catabolism, and discuss how enzymatic processes governing mitochondrial function, such as the tricarboxylic acid cycle and electron transport chain, are regulated. Understanding how deficiencies in oxygen and substrate metabolism in response to placental restriction regulate skeletal muscle and liver metabolism is essential given the importance of these tissues in the development of later lifer metabolic dysfunction.

Abstract
Alcohol consumption remains prevalent among pregnant and nursing mothers despite the well-documented adverse effects this may have on the offspring. Moderate-to-high levels of alcohol consumption in pregnancy result in fetal alcohol syndrome (FAS) disorders, with brain defects being chief among the abnormalities. Recent findings indicate that while light-to-moderate levels may not cause FAS, it may contribute to epigenetic changes that make the offspring prone to adverse health outcomes including metabolic disorders and an increased propensity in the adolescent-onset of drinking alcohol. On the one hand, prenatal alcohol exposure (PAE) causes epigenetic changes that affect lipid and glucose transcript regulating genes resulting in metabolic abnormalities. On the other hand, it can program offspring for increased alcohol intake, enhance its palatability, and increase acceptance of alcohol's flavor through associative learning, making alcohol a plausible second hit for the development of alcohol-induced liver disease. Adolescent drinking results in alcohol dependence and abuse in adulthood. Adolescent drinking results in alcohol dependence and abuse in adulthood. Alterations on the opioid system, particularly, the mu-opioid system, has been implicated in the mechanism that induces increased alcohol consumption and acceptance. This review proposes a mechanism that links PAE to the development of alcoholism and eventually to alcoholic liver disease (ALD), which results from prolonged alcohol consumption. While PAE may not lead to ALD development in childhood, there are chances that it may lead to ALD in adulthood.

Abstract
We aimed to investigate the effects of maternal tadalafil therapy on fetal programming of metabolic function in a mouse model of fetal growth restriction (FGR). Pregnant C57BL6 mice were divided into the control, L-NG-nitroarginine methyl ester (L-NAME), and tadalafil + L-NAME groups. Six weeks after birth, the male pups in each group were given a high-fat diet. A glucose tolerance test (GTT) was performed at 15 weeks and the pups were euthanized at 20 weeks. We then assessed the histological changes in the liver and adipose tissue, and the adipocytokine production. We found that the non-alcoholic fatty liver disease activity score was higher in the L-NAME group than in the control group (p < 0.05). Although the M1 macrophage numbers were significantly higher in the L-NAME/high-fat diet group (p < 0.001), maternal tadalafil administration prevented this change. Moreover, the epididymal adipocyte size was significantly larger in the L-NAME group than in the control group. This was also improved by maternal tadalafil administration (p < 0.05). Further, we found that resistin levels were significantly lower in the L-NAME group compared to the control group (p < 0.05). The combination of exposure to maternal L-NAME and a high-fat diet induced glucose impairment and non-alcoholic fatty liver disease. However, maternal tadalafil administration prevented these complications. Thus, deleterious fetal programming caused by FGR might be modified by in utero intervention with tadalafil.

Abstract
The results of different human epidemiological datasets provided the impetus to introduce the now commonly accepted theory coined as 'developmental programming', whereby the presence of a stressor during gestation predisposes the growing fetus to develop diseases, such as metabolic dysfunction in later postnatal life. However, in a clinical setting, human lifespan and inaccessibility to tissue for analysis are major limitations to study the molecular mechanisms governing developmental programming. Subsequently, studies using animal models have proved indispensable to the identification of key molecular pathways and epigenetic mechanisms that are dysregulated in metabolic organs of the fetus and adult programmed due to an adverse gestational environment. Rodents such as mice and rats are the most used experimental animals in the study of developmental programming. This review summarises the molecular pathways and epigenetic mechanisms influencing alterations in metabolic tissues of rodent offspring exposed to in utero stress and subsequently programmed for metabolic dysfunction. By comparing molecular mechanisms in a variety of rodent models of in utero stress, we hope to summarise common themes and pathways governing later metabolic dysfunction in the offspring whilst identifying reasons for incongruencies between models so to inform future work. With the continued use and refinement of such models of developmental programming, the scientific community may gain the knowledge required for the targeted treatment of metabolic diseases that have intrauterine origins.

Abstract
Lipid homeostasis is essential for normal cell physiology. Generally, lipids are stored in a lipid droplet (LD), a ubiquitous organelle consisting of a neutral lipid core and a single layer of phospholipid membrane. It is thought that LDs are generated from the endoplasmic reticulum and then released into the cytosol. Recent studies indicate that LDs can exist in the nucleus, where they play an important role in the maintenance of cell phospholipid homeostasis. However, the details of nuclear lipid droplet (nLD) generation have not yet been clearly characterized. SEIPIN is a nonenzymatic protein encoded by the Berardinelli-Seip congenital lipodystrophy type 2 (BSCL2) gene. It is associated with lipodystrophy diseases. Many recent studies have indicated that SEIPIN is essential for LDs generation. Here, we review much of this research in an attempt to explain the role of SEIPIN in nLD generation. From an integrative perspective, we conclude by proposing a theoretical model to explain how SEIPIN might participate in maintaining homeostasis of lipid metabolism.

Abstract
BACKGROUND Early life exposure to famine and adulthood obesity increased the risk of nonalcoholic fatty liver disease (NAFLD) in adulthood. However, the joint effects on adulthood NAFLD risk are not clear. AIM This study aimed to explore the joint effects of famine exposure and adulthood obesity on NAFLD risk in later life. METHODS We included 7632 subjects aged ≥40 years from a community-dwelling population. Participants were divided into 4 famine exposure groups according to the birth year, including nonexposed (1963-1974), fetal-exposed (1959-1962), childhood-exposed (1949-1958) and adolescent-exposed (1941-1948). General obesity was assessed by body mass index (BMI: overweight ≥24.0 kg/m2 , obesity ≥28.0 kg/m2 ) and abdominal obesity assessed by waist-to-hip ratio (WHR, men/women: moderate ≥0.90/0.85, high ≥0.95/0.90). RESULTS Compared with nonexposed, fetal- and childhood-exposed participants show an increased risk of NAFLD with multivariable-adjusted odds ratio (OR) and 95% confidence interval (CI) of 1.28 (1.02-1.61) and 1.40 (1.04-1.88) respectively. After further adjusting BMI and WHR, the increased risk was observed only in childhood-exposed participants (OR = 1.46, 95% CI = 1.04-2.05). Significant interaction between famine exposure and general obesity on the risk of NAFLD was observed in women (P for interaction = .02). No significant interactions were detected between famine exposure and abdominal obesity (all P for interaction >.05). Compared with normal-BMI and -WHR participants, those with both general and abdominal obesity in adulthood had 20.74 (95% CI: 12.00-35.96), 14.45 (8.76-23.86), 23.02 (16.28-32.57) and 13.04 (8.30-20.48)-fold higher risk in nonexposed, fetal-, childhood- and adolescent-exposed groups respectively. CONCLUSION Coexistence of early life famine exposure and adulthood obesity was associated with a higher risk of NAFLD.

Abstract
Abnormal lipid metabolism, oxidative stress (OS), and inflammation play a pivotal role in the increased susceptibility to neonatal fatty liver diseases associated with intrauterine growth retardation (IUGR). This study was firstly conducted to investigate whether resveratrol could alleviate IUGR-induced hepatic lipid accumulation, alteration of redox and immune status in a sucking piglet model and explore the possible mechanisms at transcriptional levels. A total of 36 pairs of 7 d old male normal birth weight (NBW) and IUGR piglets were orally fed with either 80 mg resveratrol/kg body weight/d or 0.5% carboxymethylcellulose sodium for a period of 14 days, respectively. Compared with the NBW piglets, the IUGR piglets displayed compromised growth performance and liver weight, reduced plasma free fatty acid (FFA) level, increased hepatic OS, abnormal hepatic lipid accumulation and weakened hepatic immune function, and hepatic aberrant transcriptional expression of some genes such as heme oxygenase 1, superoxide dismutase 1, sterol regulatory element-binding protein 1c, stearoyl-CoA desaturase 1, liver fatty acid-binding proteins 1, toll-like receptor 4, and tumor necrosis factor alpha (TNF-α). Oral administration of resveratrol to piglets decreased the levels of FFA and total triglycerides (TG) in the plasma and hepatic TNF-α concentration, and increased glutathione reductase activity and reduced glutathione level in the liver. Resveratrol restored the increased alanine aminotransferase activity in the plasma of IUGR piglets. Treatment with resveratrol ameliorated the increased hepatic malondialdehyde, protein carbonyl, TG, and FFA concentrations induced by IUGR. Resveratrol treatment alleviated the reduced lipoprotein lipase activity and its mRNA expression as well as TNF-α gene expression in the liver of IUGR piglets. Hepatic glutathione peroxidase 1 and monocyte chemotactic protein 1 genes expression of piglets was upregulated by oral resveratrol administration. In conclusion, resveratrol administration plays a beneficial role in hepatic redox status and lipid balance of the IUGR piglets.

Prevalence of NAFLD in Guatemala following exposure to a protein-energy nutrition intervention in early life. Ann Hepatol 2020; 19:373-379.

Abstract
INTRODUCTION AND OBJECTIVES The global prevalence of non-alcoholic fatty liver disease (NAFLD) is approximately 25%, with Hispanic populations at greatest risk. We describe the prevalence of NAFLD in a cohort of Guatemalan adults and examine whether exposure to a protein-energy supplement from conception to two years is associated with lower prevalence of NAFLD. MATERIALS AND METHODS From 1969 to 1977, four villages in Guatemala were cluster-randomized to receive a protein-energy supplement (Atole) or a no-protein, low-energy beverage (Fresco). We conducted a follow-up of participants from 2015 to 2017. We assessed blood samples (n=1093; 61.1% women; aged 37-53 years) for alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and estimated NAFLD prevalence using the liver fat score. We used generalized linear and logistic models to estimate the difference-in-difference effect of Atole from conception to two years on NAFLD. RESULTS Median ALT and AST were 19.7U/L (interquartile range, IQR: 14.1, 27.4) and 26.0U/L (IQR: 21.4, 32.8), respectively. The median NAFLD liver fat score was 0.2 (IQR: -1.2, 1.6) in women and -1.2 (IQR: -2.2, 0.5) in men (p<0.0001). The prevalence of NAFLD was 67.4% among women and 39.5% among men (p<0.0001). The association between Atole exposure from conception to two years and NAFLD was not significant (OR: 0.90, 95% CI: 0.50-1.63). CONCLUSIONS NAFLD prevalence among Guatemalan adults exceeds the global average. Protein-energy supplementation in early life was not associated with later NAFLD. There is a need for further studies on the causes and onset of NAFLD throughout the life course.

Abstract
Increasing evidence indicates that the intra-uterine environment has consequences for later life. However, the mechanisms of this fetal programming remain unclear. We aimed to investigate the impact of diet-induced maternal hypercholesterolemia on the predisposition of offspring to nonalcoholic fatty liver diseases (NAFLD) and metabolic diseases and its underlying mechanisms. Female apolipoprotein (Apo) E-deficient mice were fed a control diet (CD) or high fat/high cholesterol Western-type diet (WD) before and throughout pregnancy and lactation, and their offspring were weaned onto a CD postnatally. Strikingly, male offspring of WD-fed dams developed glucose intolerance and decreased peripheral insulin sensitivity and exhibited hepatic steatosis. Hepatic steatosis could be attributed, at least in part, to increased hepatic lipogenesis in E18.5 embryos and decreased serum VLDL levels in adulthood. In addition, males born to WD-fed dams had lower serum ApoB levels and hepatic ApoB gene expression compared with males born to CD-fed dams. DNA methylation analysis revealed increased methylation of CpG dinucleotides on the promoter region of the ApoB genes in the livers of male offspring of WD-fed dams. Our findings suggest that maternal WD intake can exacerbate the development of NAFLD in male offspring potentially by affecting ApoB gene expression through epigenetic alterations.

Abstract
This study aimed to evaluate female adult offspring induced by prenatal caffeine exposure (PCE) are susceptible to non-alcoholic fatty liver disease (NAFLD) and to explore the underlying programming mechanisms. Pregnant rats were intragastrically administered caffeine (30, 60, and 120 mg/kg.d) on gestational day (GD) 9-20. The female adult offspring were randomly divided into three groups: offspring without or with chronic stress during postnatal week (PW) 10-12 and PW28 offspring. Results showed that PW28 PCE female offspring had a higher hepatic triglyceride content and Kleiner scores, accompanied by elevated serum corticosterone levels. Moreover, the expression levels of hepatic glucocorticoid receptor (GR), CCAAT enhancer binding protein α (C/EBPα), fatty acid synthetase (FASN) and the transcription factor-sterol regulatory element binding protein 1c (SREBP1c) were increased, but SIRT1 expression was decreased. The fetal rats and PW12 offspring with chronic stress exhibited similar changes as PW28 offspring, accompanied by increased levels of H3K14ac and H3K27ac in the SREBP1c and FASN gene promoters. These effects were also observed by treating L02 cells with cortisol and were partially reversed by GR or C/EBPα siRNA or treatment with the SIRT1 agonist resveratrol. Taken together, PCE-induced high glucocorticoids levels enhanced histone modifications and expression of SREBP1c and FASN via activation of the GR-C/EBPα-SIRT1 pathway in utero. This enhanced female fetal hepatic triglyceride synthesis and continued throughout postnatal and adult life, increasing the susceptibility to adult NAFLD.

Abstract
Intrauterine growth restriction (IUGR) is an accepted risk factor for metabolic disorders in later life, including obesity and type 2 diabetes. The level of metabolic dysregulation can vary between subjects and is dependent on the severity and the type of IUGR insult. Classical IUGR animal models involve nutritional deprivation of the mother or uterine artery ligation. The latter aims to mimic a placental insufficiency, which is the most frequent cause of IUGR. In this study, we investigated whether IUGR attributable to placental insufficiency impacts the glucose and lipid homeostasis at advanced age. Placental insufficiency was achieved by deletion of the transcription factor AP-2y ( Tfap2c), which serves as one of the major trophoblast differentiation regulators. TdelT-IUGR mice were obtained by crossing mice with a floxed Tfap2c allele and mice with Cre recombinase under the control of the Tpbpa promoter. In advanced adulthood (9-12 mo), female and male IUGR mice are respectively 20% and 12% leaner compared with controls. At this age, IUGR mice have unaffected glucose clearance and lipid parameters (cholesterol, triglycerides, and phospholipids) in the liver. However, female IUGR mice have increased plasma free fatty acids (+87%) compared with controls. This is accompanied by increased mRNA levels of fatty acid synthase and endoplasmic reticulum stress markers in white adipose tissue. Taken together, our results suggest that IUGR by placental insufficiency may lead to higher lipogenesis in female mice in advanced adulthood, at least indicated by greater Fasn expression. This effect was sex specific for the aged IUGR females.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is a global epidemic in obese children and adults, and the onset might have fetal origins. A growing body of evidence supports the role of developmental programming, whereby the maternal environment affects fetal and infant development, altering the risk profile for disease later in life. Human and nonhuman primate studies of maternal obesity demonstrate that risk factors for pediatric obesity and NAFLD begin in utero. The pathologic mechanisms for NAFLD are multifactorial but have centered on altered mitochondrial function/dysfunction that might precede insulin resistance. Compared with the adult liver, the fetal liver has fewer mitochondria, low activity of the fatty acid metabolic enzyme carnitine palmitoyl-CoA transferase-1, and little or no gluconeogenesis. Exposure to excess maternal fuels during fetal life uniquely alters hepatic fatty acid oxidation, tricarboxylic acid cycle activity, de novo lipogenesis, and mitochondrial health. These events promote increased oxidative stress and excess triglyceride storage, and, together with altered immune function and epigenetic changes, they prime the fetal liver for NAFLD and might drive the risk for nonalcoholic steatohepatitis in the next generation.

Abstract
Intrauterine growth restriction (IUGR) leads to the development of metabolic syndrome in adulthood. To explore the potential mechanisms of metabolic imprinting, we investigated the effect of malnutrition in utero on hepatic unfolded protein response (UPR)-related genes in IUGR offspring. An IUGR rat model was developed by feeding a low-protein diet to pregnant rats. The expression levels and activity of hepatic UPR genes were analysed by quantitative PCR (qPCR) arrays and western blotting. The hepatic UPR molecules heat-shock 70-kDa protein 4l (Hspa4l), mitogen-activated protein kinase 10 (Mapk10), and endoplasmic reticulum to nucleus signalling 2 (Ern2) were markedly downregulated in IUGR foetuses, but the expression of Mapk10 and Ern2 returned to normal levels at 3 weeks postnatal. In contrast, cAMP responsive element binding protein 3-like 3 (Creb3l3) was upregulated in hepatic tissues at embryo 20(E20), then restored to normal in adulthood (12 weeks). The protein levels of activating transcription factor 2 (Atf2) and Atf6, two key factors of the UPR pathway, were upregulated in the livers of IUGR foetuses, and the latter remained upregulated until 12 weeks. Combined with our previous findings showing an increase in hepatic gluconeogenesis enzymes in IUGR offspring, we speculated that aberrant intrauterine milieu impaired UPR signalling in hepatic tissues; these alterations early in life might contribute to the predisposition of IUGR foetuses to adult metabolic disorders.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is a hepatic manifestation of metabolic syndrome. Its prevalence is currently increasing not only in developed obese countries but also in developing countries. Recent findings from human cohorts and animal studies suggest that a nutritional imbalance in the early critical period is causatively associated with the incidence of NAFLD in later life. Based on the current theory of the developmental origins of health and disease (DOHaD), undernourishment and overnourishment in utero are both hypothesized to prime the predisposition for hepatic fat storage. Current knowledge on the developmental origins of NAFLD is introduced in this chapter.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is a hepatic manifestation of metabolic syndrome. The prevalence of NAFLD in Japan has nearly doubled in the last 10-15 years. Increasing evidence supports undernourishment in utero being causatively connected with the risk of NAFLD in later life. Low body mass index (BMI) has been common among Japanese women of childbearing age for several decades due to their strong desire to be thin. It is plausible that insufficient maternal energy intake by pregnant Japanese women may underlie the rapid increase in the prevalence of NAFLD in Japan. In order to clarify the mechanisms by which undernourishment in utero primes adult hepatic steatosis, we developed a mouse model of fetal undernourishment with a hepatic fat deposit-prone phenotype on an obesogenic high fat diet in later life. We found that endoplasmic reticulum (ER) stress response parameters were activated concomitantly with the deterioration of hepatic steatosis and also that the alleviation of ER stress with the chemical chaperone, tauroursodeoxycholic acid (TUDCA), significantly improved hepatic steatosis. Therefore, undernourishment in utero may program the future integration of ER stress in the liver on an obesogenic diet in later life and also induce the deterioration of hepatic steatosis. These results also provide an insight into interventions for the potential high-risk population of NAFLD, such as those born small or exposed to maternal undernourishment during the fetal period, with the alleviation of ER stress by dietary supplements and/or specific food including chaperones.

Abstract
Non alcoholic fatty liver disease is linked to obesity and the metabolic syndrome. As rates of obesity rise it has become the major etiology of liver dysfunction. Despite intense study the molecular mechanisms contributing to the onset of fatty liver remain debatable. Furthermore, few therapies exist and as a result dietary therapy is commonly prescribed and remains problematic. Fibroblast growth factor is a complex metabolic regulator that is synthesized in multiple organs including the liver, with resulting complex systemic effects. Several lines of evidence suggest that effects in the liver lead to decreased fat accumulation and that treatment results in reduced inflammation and fibrosis. Understanding the physiology of FGF21 is important to the understanding of liver disease and may also provide targets for future therapy.

Abstract
We evaluated the effects of protein malnutrition on liver morphology and physiology in rats subjected to different malnutrition schemes. Pregnant rats were fed with a control diet or a low protein diet (LPD). Male offspring rats received a LPD during gestation, lactation, and until they were 60 days old (MM group), a late LPD that began after weaning (CM), or a LPD administrated only during the gestation-lactation period followed by a control diet (MC). On day 60, blood was collected and the liver was dissected out. We found a decrease in MM rats' total body (p < 0.001) and liver (p < 0.05) weight. These and CM rats showed obvious liver dysfunction reflected by the increase in serum glutamic pyruvic transaminase (SGOT) (MM p < 0.001) and serum glutamic pyruvic transaminase (SGPT) (MM and CM p < 0.001) enzymes, and liver content of cholesterol (MM and CM p < 0.001) and triglycerides (MM p < 0.01; CM p < 0.001), in addition to what we saw by histology. Liver dysfunction was also shown by the increase in gamma glutamyl transferase (GGT) (MM, MC, and CM p < 0.001) and GST-pi1 (MM and CM p < 0.001, MC p < 0.05) expression levels. MC rats showed the lowest increment in GST-pi1 expression (MC vs. MM; p < 0.001, MC vs. CM; p < 0.01). ROS production (MM, CM, and MC: p < 0.001), lipid peroxidation (MM, CM, and MC p < 0.001), content of carbonyl groups in liver proteins (MM and CM p < 0.001, MC p < 0.01), and total antioxidant capacity (MM, CM, and MC p < 0.001) were increased in the liver of all groups of malnourished animals. However, MM rats showed the highest increment. We found higher TNF-α (MM and CM p < 0.001), and IL-6 (MM and CM p < 0.001) serum levels and TGF-β liver content (MM p < 0.01; CM p < 0.05), in MM and CM groups, while MC rats reverted the values to normal levels. Pro-survival signaling pathways mediated by tyrosine or serine/threonine kinases (pAKT) (MM and CM p < 0.001; MC p < 0.01) and extrasellular signal-regulated kinase (pERKs) (MM p < 0.01; CM p < 0.05) appeared to be activated in the liver of all groups of malnourished rats, suggesting the presence of cells resistant to apoptosis which would become cancerous. In conclusion, a LPD induced liver damage whose magnitude was related to the developmental stage at which malnutrition occurs and to its length.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is associated with obesity, insulin resistance, type 2 diabetes and cardiovascular disease and can be considered the hepatic manifestation of the metabolic syndrome. NAFLD represents a spectrum of disease, from the relatively benign simple steatosis to the more serious non-alcoholic steatohepatitis, which can progress to liver cirrhosis, hepatocellular carcinoma and end-stage liver failure, necessitating liver transplantation. Although the increasing prevalence of NAFLD in developed countries has substantial implications for public health, many of the precise mechanisms accounting for the development and progression of NAFLD are unclear. The environment in early life is an important determinant of cardiovascular disease risk in later life and studies suggest this also extends to NAFLD. Here we review data from animal models and human studies which suggest that fetal and early life exposure to maternal under- and overnutrition, excess glucocorticoids and environmental pollutants may confer an increased susceptibility to NAFLD development and progression in offspring and that such effects may be sex-specific. We also consider studies aimed at identifying potential dietary and pharmacological interventions aimed at reducing this risk. We suggest that further human epidemiological studies are needed to ensure that data from animal models are relevant to human health.

Abstract
Epidemiology formed the basis of ‘the Barker hypothesis’, the concept of ‘developmental programming’ and today’s discipline of the Developmental Origins of Health and Disease (DOHaD). Animal experimentation provided proof of the underlying concepts, and continues to generate knowledge of underlying mechanisms. Interventions in humans, based on DOHaD principles, will be informed by experiments in animals. As knowledge in this discipline has accumulated, from studies of humans and other animals, the complexity of interactions between genome, environment and epigenetics, has been revealed. The vast nature of programming stimuli and breadth of effects is becoming known. As a result of our accumulating knowledge we now appreciate the impact of many variables that contribute to programmed outcomes. To guide further animal research in this field, the Australia and New Zealand DOHaD society (ANZ DOHaD) Animals Models of DOHaD Research Working Group convened at the 2nd Annual ANZ DOHaD Congress in Melbourne, Australia in April 2015. This review summarizes the contributions of animal research to the understanding of DOHaD, and makes recommendations for the design and conduct of animal experiments to maximize relevance, reproducibility and translation of knowledge into improving health and well-being.

Abstract
OBJECTIVE To determine whether maternal intrauterine undernutrition and post-weaning fish oil intake influence lipid profile in juvenile offspring, and explore the possible mechanisms at transcriptional levels. METHODS After weaning, 32 control offspring and 24 intrauterine growth retardation (IUGR) offspring were randomly allocated to standard chow or fish oil diet. At 10 weeks, fasting plasma glucose, triglycerides, total cholesterol and expressions of related hepatic genes were examined. RESULTS IUGR offspring without catch-up growth tended to develop hyperglycemia, dyslipidemia and hepatic steatosis. Down-regulation of CPT-1 and LDLR at transcriptional levels were found in IUGR offspring. Early short-term fish oil intervention reversed these unfavorable changes in juvenile rats with IUGR. The mechanisms might be mediated by decreased expression of ACC-1, increased expression of CPT-1, LDLR and ABCG5. CONCLUSION These data suggest that IUGR offspring already present lipid abnormality in juvenile stage, and early short-term fish oil consumption is beneficial to prevent these unfavorable changes.

Abstract
In order to investigate the possible involvement of endoplasmic reticulum (ER) stress in the developmental origins of hepatic steatosis associated with undernourishment in utero, we herein employed a fetal undernourishment mouse model by maternal caloric restriction in three cohorts; cohort 1) assessment of hepatic steatosis and the ER stress response at 9 weeks of age (wks) before a high fat diet (HFD), cohort 2) assessment of hepatic steatosis and the ER stress response on a HFD at 17 wks, cohort 3) assessment of hepatic steatosis and the ER stress response at 22 wks on a HFD after the alleviation of ER stress with a chemical chaperone, tauroursodeoxycholic acid (TUDCA), from 17 wks to 22 wks. Undernourishment in utero significantly deteriorated hepatic steatosis and led to the significant integration of the ER stress response on a HFD at 17 wks. The alleviation of ER stress by the TUDCA treatment significantly improved the parameters of hepatic steatosis in pups with undernourishment in utero, but not in those with normal nourishment in utero at 22 wks. These results suggest the pivotal involvement of the integration of ER stress in the developmental origins of hepatic steatosis in association with undernourishment in utero.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is fast becoming the most common liver disease globally and parallels rising obesity rates. The developmental origins of health and disease hypothesis have linked alterations in the early life environment to an increased risk of metabolic disorders in later life. Altered early life nutrition, in addition to increasing risk for the development of obesity, type 2 diabetes, and cardiovascular disease in offspring, is now associated with an increased risk for the development of NAFLD. This review summarizes emerging research on the developmental programming of NAFLD by both maternal obesity and undernutrition with a particular focus on the possible mechanisms underlying the development of hepatic dysfunction and potential strategies for intervention.

Abstract
Inadequate magnesium (Mg) intake is a widespread problem, with over 50% of women of reproductive age consuming less than the Recommended Dietary Allowance (RDA). Because pregnancy increases the requirement for Mg and the beneficial effects of magnesium sulfate for preeclampsia/eclampsia and fetal neuroprotection are well described, we examined the outcomes of Mg deficiency during pregnancy. Briefly, pregnant Swiss Webster mice were fed either control or Mg-deficient diets starting on gestational day (GD) 6 through euthanasia on GD17. Mg-deficient dams had significantly reduced weight gain and higher plasma adipokines, in the absence of inflammation. Livers of Mg-deficient dams had significantly higher saturated fatty acids (SFAs) and monounsaturated fatty acids (MUFAs) and lower polyunsaturated fatty acids (PUFAs), including docosahexaenoic acid (DHA) (P < 0.0001) and arachidonic acid (AA) (P < 0.0001). Mechanistically, Mg deficiency was accompanied by enhanced desaturase and elongase mRNA expression in maternal livers along with higher circulating insulin and glucose concentrations (P < 0.05) and increased mRNA expression of Srebf1 and Chrebp, regulators of fatty acid synthesis (P < 0.05). Fetal pups exposed to Mg deficiency were growth-restricted and exhibited reduced survival. Mg-deficient fetal livers showed lower MUFAs and higher PUFAs, with lower desaturase and elongase mRNA expression than controls. In addition, DHA concentrations were lower in Mg-deficient fetal brains (P < 0.05). These results indicate that Mg deficiency during pregnancy influences both maternal and fetal fatty acid metabolism, fetal growth and fetal survival, and support better understanding maternal Mg status before and during pregnancy.

Abstract
Intrauterine growth-restricted (IUGR) offspring are at increased risk of adult obesity, as a result of changes in energy balance mechanisms. We hypothesized that impairment of hypothalamic insulin signaling contributes to hyperphagia in IUGR offspring. Study pregnant dams were 50% food restricted from days 10 to 21 to create IUGR newborns. At 5 weeks of age, food intake was measured following intracerebroventricular (icv) injection of vehicle or insulin (10 mU) in control and IUGR pups. At 6 weeks of age, with pups in fed or fasted (48 h) states, pups received icv vehicle or insulin after which they were decapitated, and hypothalamic arcuate (ARC) nucleus dissected for RNA and protein expression. IUGR rats consumed more food than controls under basal conditions, consistent with upregulated ARC phospho AMP-activated protein kinase (pAMPK) and neuropeptide Y (NPY). Insulin acutely reduced food intake in both control and IUGR rats. Consistent with anorexigenic stimulation, central insulin decreased AMP-activated protein kinase and NPY mRNA expression and increased proopiomelanocortin mRNA expression and pAkt, with significantly reduced responses in IUGR as compared with controls. Despite feeding, IUGR offspring exhibit a persistent state of orexigenic stimulation in the ARC nucleus and relative resistance to the anorexigenic effects of icv insulin. These results suggest that impaired insulin signaling contributes to hyperphagia and obesity in IUGR offspring.

Abstract
Prenatal ethanol exposure (PEE) induces dyslipidemia and hyperglycemia in fetus and adult offspring. However, whether PEE increases the susceptibility to non-alcoholic fatty liver disease (NAFLD) in offspring and its underlying mechanism remain unknown. This study aimed to demonstrate an increased susceptibility to high-fat diet (HFD)-induced NAFLD and its intrauterine programming mechanisms in female rat offspring with PEE. Rat model of intrauterine growth retardation (IUGR) was established by PEE, the female fetus and adult offspring that fed normal diet (ND) or HFD were sacrificed. The results showed that, in PEE+ND group, serum corticosterone (CORT) slightly decreased and insulin-like growth factor-1 (IGF-1) and glucose increased with partial catch-up growth; In PEE+HFD group, serum CORT decreased, while serum IGF-1, glucose and triglyceride (TG) increased, with notable catch-up growth, higher metabolic status and NAFLD formation. Enhanced liver expression of the IGF-1 pathway, gluconeogenesis, and lipid synthesis as well as reduced expression of lipid output were accompanied in PEE+HFD group. In PEE fetus, serum CORT increased while IGF-1 decreased, with low body weight, hyperglycemia, and hepatocyte ultrastructural changes. Hepatic IGF-1 expression as well as lipid output was down-regulated, while lipid synthesis significantly increased. Based on these findings, we propose a "two-programming" hypothesis for an increased susceptibility to HFD-induced NAFLD in female offspring of PEE. That is, the intrauterine programming of liver glucose and lipid metabolic function is "the first programming", and postnatal adaptive catch-up growth triggered by intrauterine programming of GC-IGF1 axis acts as "the second programming".

Effects on transcriptional regulation and lipid droplet characteristics in the liver of female juvenile pigs after early postnatal feed restriction and refeeding are dependent on birth weight.

Abstract
Epidemiological and experimental data indicate that caloric restriction in early postnatal life may improve liver lipid metabolism in low birth weight individuals. The present study investigated transcriptional and metabolic responses to low (U) and normal (N) birth weight (d 75, T1) and postnatal feed restriction (R, 60% of controls, d 98, T2) followed by subsequent refeeding until d 131 of age (T3). Liver tissue studies were performed with a total of 42 female pigs which were born by multiparous German landrace sows. Overall, 194 genes were differentially expressed in the liver of U vs. N (T1) animals with roles in lipid metabolism. The total mean area and number of lipid droplets (LD) was about 4.6- and 3.7 times higher in U compared to N. In U, the mean LD size (µm2) was 24.9% higher. 3-week feed restriction reduced total mean area of LDs by 58.3 and 72.7% in U and N, respectively. A functional role of the affected genes in amino acid metabolism was additionally indicated. This was reflected by a 17.0% higher arginine concentration in the liver of UR animals (vs. NR). To evaluate persistency of effects, analyses were also done after refeeding period at T3. Overall, 4 and 22 genes show persistent regulation in U and N animals after 5 weeks of refeeding, respectively. These genes are involved in e.g. processes of lipid and protein metabolism and glucose homeostasis. Moreover, the recovery of total mean LD area in U and N animals back to the previous T1 level was observed. However, when compared to controls, the mean LD size was still reduced by 23.3% in UR, whereas it was increased in NR (+24.7%). The present results suggest that short-term postnatal feed restriction period programmed juvenile U animals for an increased rate of hepatic lipolysis in later life.

Abstract
An increase in susceptibility to metabolic syndromes (MetS) in rat offspring that experienced prenatal caffeine exposure (PCE) has been previously demonstrated. The present study aimed to clarify this increased susceptibility and elucidate the mechanism of foetal origin that causes or contributes to adult non-alcoholic fatty liver disease (NAFLD) as a result of PCE. Based on the results from both foetal and adult studies of rats that experienced PCE (120 mg/kgd), the foetal weight and serum triglyceride levels decreased significantly and hepatocellular ultrastructure was altered. Foetal livers exhibited inhibited insulin-like growth factor-1 (IGF-1), enhanced lipogenesis and reduced lipid output. In adult female offspring of PCE+lab chow, lipid synthesis, oxidation and output were enhanced, whereas lipogenesis was inhibited in their male conterparters. Furthermore, in adult offspring of PCE+ high-fat diet, catch-up growth appeared obvious with enhanced hepatic IGF-1, especially in females. Both males and females showed increased lipid synthesis and reduced output, which were accompanied by elevated serum triglyceride. Severe NAFLD appeared with higher Kleiner scores. Gluconeogenesis was continuously enhanced in females. Therefore, increased susceptibility to diet-induced NAFLD in PCE offspring was confirmed, and it appears to be mediated by intrauterine glucose and alterations in lipid metabolic programming. This altered programming enhanced foetal hepatic lipogenesis and reduced lipid output in utero, which continued into the postnatal phase and reappeared in adulthood with the introduction of a high-fat diet, thereby aggravating hepatic lipid accumulation and causing NAFLD.

Abstract
Exposure to an adverse intrauterine environment increases the risk for adult metabolic syndrome. However, the influence of prenatal hypoxia on the risk of fatty liver disease in offspring is unclear. The purpose of the present study was to evaluate the role of reduced fetal oxygen on the development and severity of high-fat (HF) diet-induced nonalcoholic fatty liver disease (NAFLD). Based on design implicating 2 factors, ie, maternal hypoxia (MH) and postnatal HF diet, blood lipid and insulin levels, hepatic histology, and potential molecular targets were evaluated in male Sprague Dawley rat offspring. MH associated with postnatal HF diet caused a significant increase in plasma concentration of triglycerides, free fatty acids, low-density lipoprotein cholesterol, and insulin. Histologically, a more severe form of NAFLD with hepatic inflammation, hepatic resident macrophage infiltration, and progression toward nonalcoholic steatohepatitis was observed. The lipid homeostasis changes and insulin resistance caused by MH plus HF were accompanied by a significant down-regulation of insulin receptor substrate 2 (IRS-2), phosphoinositide-3 kinase p110 catalytic subunit, and protein kinase B. In MH rats, insulin-stimulated IRS-2 and protein kinase B (AKT) phosphorylation were significantly blunted as well as insulin suppression of phosphoenolpyruvate carboxykinase and glucose-6-phosphatase. Meanwhile, a significant up-regulation of lipogenic pathways was noticed, including sterol-regulatory element-binding protein-1 and fatty acid synthase in liver. Our results indicate that maternal hypoxia enhances dysmetabolic liver injury in response to an HF diet. Therefore, the offspring born in the context of maternal hypoxia may require special attention and follow-up to prevent the early development of NAFLD.

Abstract
PURPOSE OF REVIEW The association between nutrition during pregnancy and the development of metabolic disease in the offspring has been well evidenced in humans and animals. Whilst evidence has accumulated to support various theories linking maternal diet to long-term health, the precise mechanisms of action remain poorly understood. This review summarizes recent advances within the field, focusing on the use of animal models to investigate common phenotypic outcomes. RECENT FINDINGS Continued characterization of postnatal phenotypes has highlighted the importance of postnatal diet in unmasking programming effects of prenatal diet. Whilst common phenotypes are observed across models, differences in associated regulatory processes exist dependent upon the dietary exposure used and sex of the offspring. The use of unbiased techniques at developmental stages has identified gene pathways sensitive to maternal diet, potentially explaining the induction of a common phenotype by different nutritional interventions. Evidence has also grown to support the role of epigenetic modification, with an increasing range of targets identified as being sensitive. SUMMARY A challenge remains in identifying the direct functional and long-term consequences of changes in gene expression or epigenetic status during development, and to translate these back to human populations.

Abstract
Lipid droplets (LDs) are dynamic, cytosolic lipid-storage organelles found in nearly all cell types. Too many or too few LDs during excess or deficient fat storage lead to many different human diseases. Recent insights into LD biology and LD protein functions shed new light on mechanisms underlying those metabolic pathologies. These findings will likely provide opportunities for treatment of diseases associated with too much or too little fat.

Abstract
OBJECTIVE We hypothesized that gestationally programmed nonalcoholic fatty liver disease in low-birthweight offspring is mediated through nutrient sensors nicotinamide adenine dinucleotide+-dependent histone deacetylase (SIRT1) and AMP-activated protein kinase (AMPK). STUDY DESIGN Pregnant dams received ad libitum food or were 50% food restricted from pregnancy days 10-21 to produce control and low-birthweight newborn offspring, respectively. All pups were nursed by control dams and weaned to ad libitum feed. We determined hepatic SIRT1 and AMPK activities and protein expression of lipid targets in low-birthweight and control fetuses, newborns, and adult offspring (3 months). RESULTS Low-birthweight fetuses demonstrated increased prenatal hepatic SIRT1 activity, although with increased lipogenesis. After birth, low-birthweight newborn offspring undergo postnatal suppression of hepatic SIRT1 and AMPK activities in conjunction with increased lipogenesis, decreased lipolysis, and increased fat stores. CONCLUSION These findings suggest that undernutrition stress in utero may program hepatic nutrient sensors to perceive normal postnatal nutrition as a state of nutrient excess with the induction of hepatic lipid storage.
