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.

Project description:Although mitochondrial dysfunctions are implicated in the pathogenesis of obesity, the molecular mechanisms underlying obesity-related metabolic abnormalities are still not well established. To acquire a comprehensive picture of mitochondrial molecular changes within metabolically active tissues, we focused on hepatic and muscle whole cellular transcriptome and mitochondrial proteome alterations in 16 and 48 weeks old high fat diet (HFD)-feed wild type C57BL/6J and hyperphagic, genetically modified mice with leptin dysfunction (ob/ob and db/db). On transcriptome level, the most discriminative hepatic alterations distinguished between genetically modified and wild type mice, and between overnight fasted and non-fasted mice, while the muscle transcriptional alterations related mainly to the fasting state. The fractions of uniquely different proteins were consistently higher in hyperphagic than in HFD-fed mice and in fasted than non-fasted mice . The liver samples revealed overall higher number of differentially expressed RNAs and proteins than muscle samples. Differentially expressed genes and proteins in the liver, but not in the muscle, could be assigned to several Gene Ontology terms, including oxidation-reduction and several metabolic processes. Thus, altered expression of genes and proteins accompanied the state of obesity and was quantitatively different in the liver and muscle. Our parallel microarray- and quantitative mitochondrial mass spectrometry-based study performed on hepatic and muscle samples identified a higher number of differentially expressed proteins than any other studies investigating obesity-related proteomes. However, even with our integrated transcriptomic and proteomic approach still many details and dynamics of a chain of metabolic events leading to obesity-related mitochondrial dysfunctions remain unresolved . 48 samples each of liver and muscle (total samples: 96). Samples splitted equally according to 3 criterions: age (24 young/24 old), fasting status (24 fasted/24 non fasted), and strain+diet (12 each: B6.V-Lep ob/J+D12450B, B6.BKS(D)-Lep rdb/J+D12450B, C57BL/6J+D12450B, C57BL/6J+D12492). Overall 3 replicates for each strain+diet/age/fasting_status combination. Low fat diet = D12450B; high fat diet = D12492.

Project description:The composition of the diet affects many processes in the body, including body weight and endocrine system. We have previously shown that dietary fat also affects the immune system. Mice fed high fat diet rich in polyunsaturated fatty acids survive S. aureus infection to a much greater extent than mice fed high fat diet rich in saturated fatty acids. Here we present data regarding the dietary effects on protein expression in spleen from mice fed three different diets, I) low fat/chow diet (LFD, n=4), II) high fat diet rich in saturated fatty acids (HFD-S, n=4) and III) high fat diet rich in polyunsaturated fatty acids (HFD-P, n=4). We performed mass spectrophotometry based quantitative proteomics analysis of isolated spleen by implementing the isobaric tags for relative and absolute quantification (iTRAQ) approach. Mass spectrometry data were analysed using Proteome Discoverer 2.4 software using the search engine mascot against Mus musculus in SwissProt. 924 proteins are identified in all sets (n=4) for different dietary effects taken for statistical analysis using Qlucore Omics Explorer software. Only 20 proteins were found to be differentially expressed with a cut-off value of false discovery rate < 0.1 (q-value) when comparing HFD-S and HFD-P but no differentially expressed proteins were found when LFD was compared with HFD-P or HFD-S. We identified a subset of proteins that showed an inverse expression pattern between two high fat diets. These differentially expressed proteins were further classified by gene ontology for their role in biological processes and molecular functions.

Project description:An 8-week high fat palm oil diet causes obesity and insulin resistance in C57BL/6J mice, but induces only small changes in the muscle transcriptome. Introduction: The metabolic syndrome (MS) is a cluster of metabolic abnormalities linked to an increased risk of type 2 diabetes and cardiovascular diseases. Two major characteristics of the MS are obesity and insulin resistance. In the present study we investigated the effect of obesity and insulin resistance on the mouse muscle transcriptome. Methods: C57BL/6J mice were fed a palm oil-based low fat diet (LFD) or high fat diet (HFD) for eight weeks. Microarray analysis was performed by using two complementary strategies: (1) 8-week HFD transcriptome versus 8-week LFD transcriptome and (2) transcriptome of mice sacrificed at the start of the intervention versus 8-week LFD transcriptome and 8-week HFD transcriptome, respectively. Results: HFD mice develop obesity and whole-body insulin resistance. Despite these metabolic disturbances we found that HFD induces relatively small changes in gene expression (< 1.3 fold). Only the up-regulation of FA oxidation and the down-regulation of the MAPK cascade were specific for the HFD intervention. Eight-weeks of aging induced more changed gene expression levels than the HFD, including genes involved in cell-cell interaction and development. Conclusion: Eight weeks of aging induce more pronounced changes in the muscle transcriptome than an HFD. Since only one strategy revealed the transcriptional down-regulation of the MAPK cascade, whereas both strategies showed the up-regulation of FA oxidation we suggest the use of complementary analysis strategies by the genome-wide search of gene expression changes induced by mild interventions, such as an HFD. Keywords: diet intervention and time course In this study, C57BL/6J mice were fed a high fat (HF) diet for 8 weeks to induce obesity and insulin resistance. Plasma levels of the adipokines leptin and adiponectin were measured. To investigate how these metabolic disturbances will influence the skeletal muscle transcriptome we performed whole-genome microarray analysis. Functional implications were assessed by analyses of predefined gene sets based on Gene Ontology, biochemical, metabolic and signaling pathways.

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:In order to establish an obese mouse model, female mice were continuously fed with a high-fat diet (HFD) or a normal diet (control) for 16 weeks beginning at three weeks of age. In this paper, these mice are termed ‘HFD mice’ and ‘control mice’, respectively. Accordingly, we call their oocytes ‘HFD oocytes’ and ‘control oocytes’. Substantial evidence indicates that the effects of maternal obesity on embryo/offspring development can be attributed to factors within the oocyte (9). To identify such potential effectors, we performed a comparative proteomic analysis of ovulated MII oocytes from control and HFD mice.

Project description:The popularity of high fat foods in modern society has been associated with epidemic of various metabolic diseases characterized by insulin resistance, the pathology of which involves complex interactions between multiple tissues such as liver, skeletal muscle and white adipose tissue (WAT). To uncover the mechanism by which excessive fat impairs insulin sensitivity, we conducted a multi- tissue study by using TMT-based quantitative proteomics. 3-week-old ICR mice were fed with high fat diet (HFD) for 19 weeks to induce insulin resistance. Liver, skeletal muscle and epididymal fat were collected for proteomics screening. Additionally, PRM was used for validating adipose differential proteins. By comparing tissue-specific protein profiles of HFD mice, multi-tissue regulation of glucose and lipid homeostasis and corresponding underlying mechanisms was systematically investigated and characterized. NC: normal birth weight + chow diet; NH: normal birth weight + high fat diet; LC: low birth weight + chow diet; LH: low birth weight + high fat diet.
