Project description:Modern lifestyle is associated with a major consumption of ultra-processed foods (UPF) due to their practicality and palatability. The ingestion of emulsifiers, a main additive in UPFs, has been related to gut inflammation, microbiota dysbiosis, adiposity and obesity. Maternal unbalanced nutritional habits during embryonic and perinatal stages perturb offspring’s long-term metabolic health, thus increasing obesity and associated comorbidity risk. However, whether maternal emulsifier consumption influences developmental programming in the offspring remains unknown. Here we show that, in mice, maternal consumption of dietary emulsifiers (1% CMC and 1% P80 in drinking water), during gestation and lactation, perturbs the development of hypothalamic energy balance regulation centers of the progeny, leads to metabolic impairments, cognition deficits and induces anxiety-like traits in a sex-specific manner. Our findings support the notion that maternal consumption of emulsifiers, common additives of UPFs, causes mild metabolic and neuropsychological malprogramming in the progeny. Our data call for nutritional advice during gestation.

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:Early-life factors, including nutrition, shape long-term health outcomes. Despite the essential role of lactation in maternal nutritional support, the influence of epigenetic factors on lactation and postnatal growth remains poorly understood. Zinc-finger protein 57 (ZFP57), is an epigenetic regulator of genomic imprinting, a process that directs gene expression based on parental origin, playing a vital role in mammalian prenatal growth. Here, we identify a novel function of ZFP57 in the mammary glandI, where it serves as a key modulator of postnatal resource control, independently of imprinted genes. ZFP57 regulates multiple aspects of mammary gland functions, including ductal branching and cellular homeostasis. Its absence leads to significant differential gene expression, related to alveologenesis, lactogenesis and milk synthesis, associated with delayed lactation and altered milk composition. This results in life-long impacts on offspring including the development of metabolic syndrome. Cross-fostering reveals intricate dynamics between mother and offspring during lactation. Pups raised by a dam of a different genotype than their birth mother exhibit exacerbated metabolic features in adulthood, providing additional novel insight into the programming of offspring long-term health by maternal context. This study deepens our understanding of the interplay between epigenetic factors, lactation, and postnatal resource control.

Female F0 founders were raised on a standard diet in a normal cage until 12 weeks of age, at which point they were placed into the enriched environmental cage or stayed in the normal cage (chosen at random) for 4 weeks. Males were always raised on a standard diet in the standard cage. At 16 weeks, female F0 founders were mated with males in standard conditions. After 1 or 2 days, males were removed, and pregnant females were left alone with a standard diet in the standard cage until their litters were 3 weeks of age. Note that we always used virgin males to avoid confounding effects brought about by the males. Moreover, males mated with two female groups did not differ in phenotypic data (body weight, adiposity, fasting blood glucose and insulin levels). At 3 weeks of age, partial offspring were sacrificed and the median lobe of liver was rapidly dissected out and flash-frozen in liquid N2, each from an independent mother. Samples from five control and four slimming offspring, each from different mothers, were chosen for microarray analysis.
