Efect of neonatal nutrition on adipose tissue remodeling genes during early development and in adult mice

ABSTRACT: While the phenomenon linking the early nutritional environment to disease susceptibility exists in many mammalian species, the underlying mechanisms are unknown. We hypothesized that nutritional programming is a variable quantitative state of gene expression, fixed by the state of energy balance in the neonate, that waxes and wanes in the adult animal in response to changes in energy balance. We tested this hypothesis with an experiment, based upon global gene expression, to identify networks of genes in which expression patterns in inguinal fat of mice have been altered by the nutritional environment during early post-natal development. Gene expression patterns in inguinal fat was assessed at 5, 10, 21 days of age and as adults fed chow (56 days of age) followed by high fat diet for 8 weeks (112 days of age) for C57BL/6J mice reared by lactating dams fed either a control diet (CONT), lactating dams fed a diet in which food intake was restricted to cause under-nourishment (lactation under-nutrition; LUN); and, lactating dams fed a high fat diet in where the number of progeny was limited to four (lactation over-nutrition; LON) . 15 samples with 3 technical replicates of each sample. Each of the 15 samples consisted of pooled total RNA from 12 male mice. Dietary control samples are included for each time period.

Project description:Objective: Procyanidins are polyphenolic bioactive compounds that exert beneficial effects against obesity and its related diseases. The aim of this study was to evaluate whether the supplementation with low doses of a grape seed procyanidin extract (GSPE) to dams during pre and postnatal periods has biological effects on their offspring at youth. Design: The metabolic imprinting effect of GSPE was evaluated in 30 days-old male offspring of four groups of rats that were fed either a standard diet (STD) or a high-fat diet (HFD) and supplemented with either GSPE at 25 mg per kg of body weight/day or vehicle during pregnancy and lactation. Results: A significant increase in the adiposity index and in the weight of all the white adipose tissue depots studied (retroperitoneal â??RWAT-, mesenteric â??MWAT-, epididymal â??EWAT- and inguinal â??IWAT-) was observed in offspring of dams fed with a HFD and treated with GSPE (HFT group), compared to the offspring of dams fed with the same diet and that do not received procyanidins (HF group). HFT animals also showed a higher number of cells in the EWAT, a sharply decrease of the circulating levels of monocyte chemoattractant protein-1 (MCP-1) as well as a moderate, but significant, decrease of plasma glycerol levels. The transcriptomic analysis performed in the EWAT showed 238 genes differentially expressed between HF and HFT animals, covering an entire range of processes related with the immune function and the inflammatory response (the metabolic pathway mainly reflected in the EWAT), adipose tissue remodeling and function, lipid and glucose homeostasis and metabolism of methyl groups. Conclusion: GSPE treatment to dams fed a HFD during pregnancy and lactation increases adiposity, decreases the circulating levels of MCP-1 and modulates the expression of key genes involved in the adipose tissue metabolism of their offspring. The microarray study was performed with the EWAT RNA samples of rats from the HF and the HFT groups (n=8 animals each).

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:There is increasing appreciation for sexually dimorphic effects, but the molecular mechanisms underlying these effects are only partially understood. In the present study, we explored transcriptomics and epigenetic differences in the small intestine and colon of prepubescent male and female mice. In addition, the microbiota composition of the colonic luminal content has been examined. At postnatal day 14, male and female C57BL/6 mice were sacrificed and the small intestine, colon and content of luminal colon were isolated. Gene expression of both segments of the intestine was analysed by microarray analysis. DNA methylation of the promoter regions of selected sexually dimorphic genes was examined by pyrosequencing. Composition of the microbiota was explored by deep sequencing. Sexually dimorphic genes were observed in both segments of the intestine of 2-week-old mouse pups, with a stronger effect in the small intestine. Amongst the total of 349 genes displaying a sexually dimorphic effect in the small intestine and/or colon, several candidates exhibited a previously established function in the intestine (i.e. Nts, Nucb2, Alox5ap and Retnlγ). In addition, differential expression of genes linked to intestinal bowel disease (i.e. Ccr3, Ccl11 and Tnfr) and colorectal cancer development (i.e. Wt1 and Mmp25) was observed between males and females. Amongst the genes displaying significant sexually dimorphic expression, nine genes were histone-modifying enzymes, suggesting that epigenetic mechanisms might be a potential underlying regulatory mechanism. However, our results reveal no significant changes in DNA methylation of analysed CpGs within the selected differentially expressed genes. With respect to the bacterial community composition in the colon, a dominant effect of litter origin was found but no significant sex effect was detected. However, a sex effect on the dominance of specific taxa was observed. This study reveals molecular dissimilarities between males and females in the small intestine and colon of prepubescent mice, which might underlie differences in physiological functioning and in disease predisposition in the two sexes. Small intestine and colon were isolated from two-week old pups of dams fed a low-fat diet and subjected to gene expression profiling

Project description:During lactation, mammary epithelial secretory cells secrete huge amounts of milk from their apical side. The major milk proteins, the caseins, are secreted by exocytosis, while milk fat globules are released by budding, enwrapped by the plasma membrane. Due to the number and large size of milk fat globules, the membrane surface needed for their secretion might exceed that of the apical plasma membrane. In order to identify the cellular compartments that may provide membrane during the budding of milk fat globules, a large-scale proteomics analysis of both cytoplasmic lipid droplets and secreted milk fat globules membranes was performed in mouse cells. The differential analysis of the protein profiles of these two organelles strongly suggest that, in addition to the apical plasma membrane, at least the endoplasmic reticulum, the secretory vesicles containing caseins, and potentially the mitochondria contribute to the formation of the milk fat globule membrane. Moreover, the specific analysis of the membrane-associated as well as the raft-associated proteins reinforces this possibility and points to a role for lipid rafts in milk product secretion. The subcellular localization of several major proteins of the cytoplasmic lipid droplets or of the milk fat globule membrane was investigated by immunofluorescence in lactating mammary epithelial cells. Furthermore, the localization of GM1 ganglioside, a known marker of lipid rafts and of free cholesterol, showed a clear association with both cytoplasmic lipid droplets and secreted milk fat globules. Additionally, the presence of some SNARE proteins that may be involved in casein exocytosis and of two Rab GTPases on both cytoplasmic lipid droplets and milk fat globules was demonstrated by immunofluorescence. Altogether, our results provide evidence for a pivotal role of the endoplasmic reticulum as membrane contributor to milk fat globule budding, and suggest that some SNARE proteins may spatio-temporally coordinate the secretion of milk products.
