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:We tested if minor changes in maternal non-shivering thermogenesis during pregnancy can severely alter the phenotype of the offspring already in the next generation. Therefore, male offspring of dams lacking the uncoupling protein 1 (UCP1-KO) in the thermogenic brown adipose tissue were analysed. Genome-wide expression profiling identified several alterations in the hepatic transcriptomic landscape, demonstrating that even minor differences in the demand for maternal thermogenesis profoundly and permanently alter hepatic gene activity in the adult offspring. Liver gene expression data of offspring from WT and UCP1-KO dams.

Project description:Fiber diet plays a beneficial role in neurocognitive disorders, like dementia and Alzheimer’s Disease. However, insufficient fiber consumption in public increases the concern about public health, particularly about neurocognitive diseases. To survey the association between fiber dietary and neurocognitive performances, mice were subjected to normal-fiber diet or low-fiber diet during gestation, and the neurocognitive functions of the offspring were assessed. We found that maternal low-fiber diet impaired the cognitive functions, and the impairments can be reversed by butyrate, rather than propionate intake. Mechanism studies showed that HDAC4 might become the most potential mediator in butyrate-dependent neurocognitive improvement. Besides, using human maternal serum and paired umbilical cord blood samples, we demonstrated that the SCFA levels in offspring are positively correlated with levels in maternal serum. Those results provide a solid basis for not only maternal fiber diet regulates neurocognitive functions in offspring through altering SCFA levels, but clinical practice in SCFAs-dependent maternal intervention for offspring health.

Project description:We tested if minor changes in environmental temperature during pregnancy can severely alter the phenotype of the offspring already in the next generation. Genome-wide expression profiling of liver samples obtained from adult male mice offspring identified several alterations in the hepatic transcriptomic landscape, thus demonstrating that even minor differences in the demand for maternal thermogenesis profoundly and permanently alter hepatic gene activity in the adult offspring. Liver gene expression data of offspring from dams that were kept at different ambient temperatures (30°C, 23°C, 18°C, 10°C) only during pregnancy.

Project description:TNF is a proinflammatory cytokine with established roles in host defense and immune system organogenesis. Here we report a novel physiological function of TNF that extends its effect beyond the host into the developing offspring. A partial/complete maternal TNF-deficit, specifically in hematopoietic cells, resulted in reduced milk levels of chemokines IP-10, MCP-1/-3/-5, and MIP-1β, which in turn, augmented offspring postnatal hippocampal proliferation, leading to improved adult spatial memory. These effects were reproduced by the postpartum administration of a clinically used anti-TNF agent. Chemokines, fed to suckling pups of TNF-deficient mothers, restored both postnatal proliferation and adult spatial memory to normal levels. This work identifies a TNF-dependent “lactrocrine” pathway that programs offspring hippocampal development and memory. The level of ambient TNF is known to be downregulated by physical activity/exercise and adaptive stress; thus, we propose that the maternal TNF-milk chemokine pathway evolved to promote offspring adaptation to post-weaning environmental challenges/competition.

Project description:Maternal exposure during pregnancy is a strong determinant of offspring health outcomes. Such exposures induce changes in the offspring epigenome resulting in gene expression and functional changes. In this study, we investigated the effect of maternal Western hypercaloric diet (HCD) programming during the perinatal period and its effect on neuronal plasticity and cardiometabolic health in adult offspring. C57BL/6J dams were fed HCD for 1 month prior to mating with regular diet (RD) sires and kept on the same diet throughout pregnancy and lactation. At weaning, offspring were maintained on either HCD or RD for 3 months duration. Maternal programming resulted in male-specific hypertension and hyperglycemia, with both males and females showing increased sympathetic tone to the vasculature. Surprisingly, programmed male offspring fed on HCD exhibited lower glucose levels, less insulin resistance, and leptin levels compared to non-programmed HCD-fed male mice. Hypothalamic genes involved in glial and astrocytic differentiation were differentially methylated in programmed male offspring. Genes involved in inflammation and type 2 diabetes were targeted by differentially expressed miRNA in programmed male offspring. Methyl-seq data were supported by our findings of astrogliosis and microgliosis as well as increased microglial activation in programmed males in the paraventricular nucleus (PVN). Aligned with programming-induced protective effect in HCD male mice, we observed lower protein levels of hypothalamic TGFβ2, NF-κB2, NF-κBp65, Ser-pIRS1, and GLP1R compared to non-programmed HCD-fed male mice. In conclusion, our study shows that maternal HCD programs neuronal plasticity in the offspring and results in male-specific hypertension and hyperglycemia. On the other hand, we observed a compensatory role of programming potentially by priming metabolic pathways to handle excess nutrients in a more efficient way.
