Project description:Early-life exposure to high-fat diet (HF) can program metabolic and cognitive alterations in adult offspring. Although the hippocampus plays a crucial role in memory and metabolic homeostasis, few studies reported the impact of maternal HF on this structure. We assessed the effects of maternal HF during lactation on physiological, metabolic and cognitive parameters in young adult offspring mice. To identify early-programming mechanisms in hippocampus, we developed a multi-omics strategy in male and female offspring. Maternal HF induced a transient increased body weight at weaning, a mild glucose intolerance only in 3-month-old male mice with no change in plasma metabolic parameters in adult male and female offspring. Behavioral alterations revealed by Barnes maze test were observed both in 6-month-old male and female mice. Multi-omics strategy unveiled sex-specific transcriptomic and proteomic modifications in the hippocampus of adult offspring. These studies, that were confirmed by regulon analysis, showing that, although genes whose expression was modified by maternal HF were different between sexes, the main pathways affected were similar with mitochondria and synapses as main hippocampal targets of maternal HF. The effects of maternal HF reported here may help to better characterize sex-dependent molecular pathways involved in cognitive disorders and neurodegenerative diseases.

Project description:Maternal diet is associated with the development of metabolism-related and other non-communicable diseases in offspring. Underlying mechanisms, functional profiles, and molecular markers are only starting to be revealed. Here, we explored the physiological and molecular impact of maternal Western-style diet on the liver of male and female offspring. C57BL/6 dams were exposed to either a low fat/low cholesterol diet (LFD) or a Western-style high fat/high cholesterol diet (WSD) for six weeks before mating, as well as during gestation and lactation. Dams and offspring were sacrificed at postnatal day 14, and body, liver, and blood parameters were assessed. The impact of maternal WSD on the pups' liver gene expression was characterised by whole-transcriptome microarray analysis. Exclusively male offspring had significantly higher body weight upon maternal WSD. In offspring of both sexes of WSD dams, liver and blood parameters, as well as hepatic gene expression profiles were changed. In total, 686 and 604 genes were differentially expressed in liver (pM-bM-^IM-$0.01) of males and females, respectively. Only 10% of these significantly changed genes overlapped in both sexes. In males, in particular alterations of gene expression with respect to developmental functions and processes were observed, such as Wnt/beta-catenin signalling. In females, mainly genes important for lipid metabolism, including cholesterol synthesis, were changed. We conclude that maternal WSD affects physiological parameters and induces substantial changes in the molecular profile of the liver in two-week-old pups. Remarkably, the observed biological responses of the offspring reveal pronounced sex-specificity. C57BL/6 dams were exposed to either a low fat/low cholesterol diet (LFD) or a Western-style high fat/high cholesterol diet (WSD) as six weeks pre-treatment before mating, as well as during gestation and lactation. Offspring were sacrificed at postnatal week two, livers were removed and RNA samples were subjected to gene expression profiling.

Project description:Background: Epidemiological studies suggest an association between maternal obesity and adverse neurodevelopmental outcomes in offspring. Objective: To compare the global proteomic portrait in the cerebral cortex between mice born to mothers on a high-fat or control diet who themselves were fed a high-fat or control diet. Methods: Male mice born to dams fed a control (C) or high fat (H) diet four weeks before conception and during gestation and lactation were assigned to either C or H diet at weaning. Mice (n=24) were sacrificed at 19-weeks and their cerebral cortices were pooled into 8 samples and analysed using an iTRAQ based 2D LC-MS methodology. Results: A total of 6,695 proteins were identified and fully quantified (q<0.01). Approximately 10% of these proteins demonstrated a minimum of one Standard Deviation of regulation across all biological replicates in at least one of the experimental groups (CH, HC, HH) relative to the control (CC). Principal component analysis and hierarchical clustering analysis showed that mice clustered based on the diet of the mother and not their current diet. In silico bioinformatics analysis revealed that maternal high-fat diet was significantly associated with response to hypoxia/oxidative stress and apoptosis in the cerebral cortex of the adult offspring. Conclusion: Maternal high-fat diet was associated with distinct endophenotypic changes of the adult mouse cerebral cortex independent of the diet of the offspring. The identified modulated proteins could represent novel therapeutic targets for the prevention of neuropathological features resulting from maternal obesity.

Project description:Slimming is globally prevalent especially in young women, and it may contribute to the metabolic health of their offspring. Whereas some Lamarckian ideas about environmental inheritance have been dismissed, increasing evidence suggest that certain acquired traits can be transmitted to the next generation. It is therefore of great interest to determine how and to what extent a maternal lifestyle change contributes to their offspring. Here we show that enriched environment (EE) induced maternal slimming improves general health and reprograms metabolic gene expression in mice offspring. EE in mothers induced decreased body weight, adiposity, and improved glucose tolerance and insulin sensitivity. Relative to controls, their offspring exhibited improved general health such as reduced fat accumulation, enhanced metabolic parameters as well as glucose tolerance and insulin sensitivity. Maternal slimming altered the expression of 1,732 genes in the liver of offspring, with coherent downregulation of genes involved in lipid and cholesterol biosynthesis. Epigenomic profiling in offspring revealed numerous changes in cytosine methylation depending on maternal slimming, including hypermethylation of several genes involved in lipid biosynthesis, correlated with the downregulation of these genes. Maternal slimming also altered overall transcriptome patterns in mature oocytes, which contributes largely to the metabolic health and gene expression patterns in offspring. Overall, our studies suggest that maternal slimming have a beneficial role in regulating metabolic profiles in offspring, implying that it might be considered as a potential strategy to reverse the global prevalence of obesity and related metabolic syndromes. Examination of the effect of 2 different maternal lifestyles, control and slimming, on the mRNA expression in the mature oocytes of the female mice. Naturally ovulated mature oocytes (MII stage) were collected from 3 control and 3 slimming female F0 founders (3 oocytes per mouse, 9 oocytes for each group).

Project description:Enhanced prenatal fatty streak formation in human fetuses has been associated with maternal hypercholesterolemia. However, the possible roles of maternal genetic background and in utero environment on development of atherosclerosis in adult life have not been unraveled. We generated genetically identical heterozygous apoE-deficient mice offspring with a different maternal background to study the intrauterine effect of maternal genotype and associated hypercholesterolemia on the developing vascular system. As read out for increased atherosclerosis development in adult life, a constrictive collar was placed around the carotid artery to induce lesion formation. A significant increase in endothelial cell activation and damage was detected in the carotid arteries of heterozygous apoE-deficient fetuses with apoE-deficient mothers compared with offspring from wild type mothers, but no fatty streak formation was observed. Postnatally, all carotid arteries revealed normal morphology. In adult offspring with maternal apoE-deficiency, the constrictive collar resulted in severe lesion (9/10) development compared with no to only minor lesions (2/10) in offspring of wild type mothers. Microarray analysis showed no effect of maternal apoE-deficiency on gene expression in adult offspring. We conclude that maternal apoE-deficiency not only affects fetal arteries, but also increases the susceptibility for development of collar-induced atherosclerosis in adult life.

Project description:Maternal nutrition during embryonic development and lactation influences multiple aspects of offspring health. Using mice, this study investigates the effects of maternal caloric restriction (CR) during mid-gestation and lactation on offspring neonatal development and on adult metabolic function when challenged by a high fat diet (HFD). The CR maternal model produced male and female offspring that were significantly smaller, in terms of weight and length, and females had delayed puberty. Adult offspring born to CR dams had a sexually dimorphic response to the high fat diet. Compared to offspring of maternal control dams, adult female, but not male, CR offspring gained more weight in response to high fat diet at 10 weeks. In adipose tissue of male HFD offspring, maternal undernutrition resulted in blunted expression of genes associated with weight gain and increased expression of genes that protect against weight gain. Regardless of maternal nutrition status, HFD male offspring showed increased expression of genes associated with nonalcoholic liver disease (NAFLD). Furthermore, we observed significant, sexually dimorphic differences in serum TSH. These data reveal tissue- and sex-specific changes in gene and hormone regulation following mild maternal undernutrition, which may offer protection against diet induced weight gain in adult male offspring.
