Project description:Analysis of gene expression in adipose tissue of female mice after continuous high fat diet (HFD) feeding for three generations. The hypothesis in this study is that continuous HFD feeding has transgenerational amplification effects to the offspring. Results provide important information on the impacts of over-nutrition over one generation on the offspring, such as transgenerational up-regulated or down-regulated genes.

Project description:Compelling evidence supports that gestational chronodisruption induces major changes in maternal circadian rhythms, fetal development and that these changes impact adult life at many physiological levels. Using a rat model of chronic photoperiod shifting throughout gestation (CPS), we investigated the detrimental effects of gestational CPS on glucose homeostasis, adipose tissue physiology and metabolism in the adult male offspring. At proteomic level, in CPS adipose tissue, 275 proteins displayed differential expression, compared with LD animals fed with a standard diet. Interestingly, CPS offspring and LD fed with HFD showed 20 proteins in common (2 upregulated 18 downregulated). Based on these common proteins, the IPA analysis found that 2 functional pathways were significantly altered; the network 1 (AKT/ERK) and the network 2 (TNF/IL4).

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:The objective of the experiment was to dissect the effects of a high-fat diet on juvenile adipose tissue gene expression under conditions of excess calorie intake versus normal calorie intake in comparison to a standard low-fat diet. For this purpose juvenile mice were fed (A) a standard low-fat diet (CD), (B) a high-fat diet ad libitum (excess calorie intake) (HFD) and (C) a high-fat diet with calorie consumption restricted to the calorie consumption of the CD diet (R-HFD). RNA expression was profiled after 1 week of feeding in the periuterine fat depot.

Project description:We have previously reported that providing a control diet to obese and diabetic mice during the periconceptional/gestation/lactation period, led to a drastic sex-specific shift from susceptibility to resistance to high fat feeding (HFD) in the female offspring. In the present study, we aimed to characterize exhaustively the metabolic phenotype of F1 and F2 sensitive (S1, S2) and resistant (R1, R2) mice and underscore in the liver, muscle and adipose tissue, the transcriptional and epigenetic mechanisms supporting the response to HFD, the trait of resistance/susceptibility and the adaptation across generations. We report the transcriptomic analyses realized based on a candidate gene approach in the liver using a custom mouse microchip. A direct comparison strategy with dye-swapping was used to compare two conditions and dye-swaps were replicated several times with at least 4 different animals/group. The comparisons of primary interest: S1 vs N1 (S1/N1); S2 vs N2 (S2/N2); R2 vs N2 (R2/N2); R2 vs S2 (R2/S2) and S2 vs S1 (S2/S1) were made according to a design such that secondary comparisons could be estimated.

Project description:Maternal obesity can program metabolic syndrome in offspring but the mechanisms are not well characterized. Moreover, the consequences of maternal overnutrition in the absence of frank obesity remain poorly understood. This study aimed to determine the effects of maternal consumption of a high fat-sucrose diet on the skeletal muscle metabolic and transcriptional profiles of adult offspring. Female Sprague Dawley rats were fed either a diet rich in saturated fat and sucrose (HFD, 23.5% fat, 20% sucrose wt/wt) or a standard chow diet (NFD, 7% fat, 10% sucrose w/w) for the 3 weeks prior to mating and throughout pregnancy and lactation. Although maternal weights were not different between groups at conception or weaning, HFD dams were ~22% heavier than chow fed dams from mid-pregnancy until 4 days post-partum. Adult male offspring of HFD dams were not heavier than controls but demonstrated features of insulin resistance including elevated plasma insulin concentration (+40%, P<0.05). Next Generation mRNA Sequencing was used to identify differentially expressed genes in the soleus muscle of offspring, and Gene Set Enrichment Analysis (GSEA) to detect coordinated changes that are characteristic of a biological function. GSEA identified 15 pathways enriched for up-regulated genes, including cytokine signaling (P<0.005), starch and sucrose metabolism (P<0.017), and inflammatory response (P<0.024). A further 8 pathways were significantly enriched for down-regulated genes including oxidative phosphorylation (P<0.004) and electron transport (P<0.022). Western blots confirmed a ~60% reduction in the phosphorylation of the insulin signaling protein Akt (P<0.05) and ~70% reduction in mitochondrial complexes II (P<0.05) and V expression (P<0.05). On a normal diet, offspring of HFD dams developed an insulin resistant phenotype, with transcriptional evidence of muscle cytokine activation, inflammation and mitochondrial dysfunction. These data indicate that maternal overnutrition, even in the absence of pre-pregnancy obesity can promote metabolic dysregulation and predispose offspring to type 2 diabetes. Messenger RNA profile of skeletal muscle of male offspring from female Sprague Dawley rats fed either a diet rich in saturated fat and sucrose (HFD, 23.5% fat, 20% sucrose wt/wt) or a standard chow diet (NFD, 7% fat, 10% sucrose w/w) for the 3 weeks prior to mating and throughout pregnancy and lactation. There were 5 HFD samples compared to 6 NFD control samples.

Project description:We demonstrated that RORa-deficient staggerer mice (RORasg/sg) fed with a high fat diet (HFD) showed reduced adiposity and hepatic triglyceride levels compared to wild type (WT) littermates and were resistant to the development of hepatic steatosis, adipose-associated inflammation, and insulin resistance. Gene expression profiling showed that many genes involved in triglyceride synthesis and storage, including Cidec, Cidea, and Mogat1, were expressed at much lower levels in liver of RORasg/sg mice. In addition to reduced lipid accumulation, inflammation was greatly diminished in white adipose tissue (WAT) of RORasg/sg mice fed with a HFD. The infiltration of macrophages and the expression of many immune-response and pro-inflammatory genes, including those encoding various chemo/cytokines, toll-like receptors, and TNF signaling proteins, were significantly reduced in RORasg/sg WAT. Moreover, RORasg/sg mice fed with a HFD were protected from the development of insulin resistance. Together, these results indicate that RORa plays a critical role in the regulation of several aspects of metabolic syndrome. Therefore, RORa may provide a novel therapeutic target in the management of obesity and associated metabolic diseases. Liver and white adipose tissue (WAT) total RNAs were purified from 5 WT and 5 RORasg/sg (natural deletion of RORa gene in mice) mice fed with a high fat diet for 6 weeks. Then samples were applied on Agilent mouse genome chip.

Project description:Using standardized, semipurified diets is a crucial factor for reproducibility of experimental nutritional studies. For the purpose of comparability and integration of research, two European consortia, Mitofood and BIOCLAIMS, proposed an AIN-93-based standard reference diet, the standardized BIOCLAIMS low-fat diet (LFD) as well as a high-fat diet (HFD). In order to evaluate the BIOCLAIMS LFD and HFD, we performed short-term (5 days) and long-term (12 weeks) feeding experiments using male C57BL/6 mice. The HFD has the same composition as the LFD except the fat content is increased to 40% energy in exchange for carbohydrates. Both diets were accepted by the animals and proof of principle was given that the BIOCLAIMS HFD increases body weight and body fat and affects glucose homeostasis. Short-term feeding trials (5 days) were performed in order to identify metabolic and molecular parameters which can serve as acute predictors for metabolic disorders due to high-fat diet-induced obesity. We analyzed gene expression in gonadal white adipose tissue of short- and long-term fed animals with whole genome microarrays. The BIOCLAIMS HFD strongly influenced gene expression in white adipose tissue after short- and long-term intervention. A total number of 973 and 4678 transcripts were significantly different between both diets after 5 days feeding and 12 weeks feeding, respectively. A total number of 764 transcripts encoding 549 genes were significantly differentially regulated between LF and HF animals after 12 weeks feeding as well as after 5 days feeding. Of these 549 overlapping genes, a substantial number (434 genes) were expressed at a lower level and 115 genes were expressed at a higher level in the HF mice compared to the LF mice. Without exception, all genes were regulated equally. Pathway analysis revealed a prominent role for genes involved in lipid metabolism, carbohydrate metabolism and oxidative phosphorylation. This was confirmed by quantitative real-time reverse transcription PCR. The high predictive value of gene expression changes in our short-term study compared to long-term high fat feeding is a promising step to get well-defined, early biomarkers that could shorten animal trials considerably and allow a more rapid and efficient screening of different compounds. C57BL/6J wildtype male mice, aged 12 weeks, received a low-fat diet or a high-fat diet for 5 days or 12 weeks. After sacrification, white adipose tissue depots were dissected, and immediately snap frozen in liquid nitrogen. Total RNA was isolated, quantified and qualified, and subsequently used for global gene expression profiling using Agilent 4x44K microarrays.

Project description:The present study aimed to examine the effect of high-fat diet prior to pregnancy on the liver of mouse offspring. Female C57BL/6J mice were fed a normal chow (15.2% fat by energy) (CTR and CTR-PP groups) or a high-fat chow (31.2% fat by energy) (HFD and HFD-PP groups) for 3−4 weeks and then mated with male C57BL/6J mice fed normal chow. Some mothers continued on the same diet until pups reached 21 days of age (CTR and HFD), and others were fed the different chows from gestational day 0 (CTR-PP and HFD-PP) to determine the effects of a high-fat diet during the pre-pregnancy period in HFD-PP/CTR and HFD/CTR-PP comparisons. RNA sample was taken from liver of 3-week-old mouse prenatally received high-fat diet prior to pregnancy, during pregnancy and lactation, or through prior to and during pregnancy and lactation, while control RNA was taken from control counterpart prenatally received normal diet alone. Comparisons among groups were made by one-color method with normalized data from Cy3 channels for data analysis.
