Project description:Expression of genes related to fibrosis was assessed in the liver of AIM+/+ and AM-/- mice fed a high-fat diet (HFD) for various period. Overall, there was no significant difference in the magnitude of expression of fibrosis-related genes during the steatosis progression. AIM+/+ and AIM-/- mice were fed an HFD for 0, 12 or 20 weeks. Liver samples were homogenized with Trizol, and total RNA was extracted according to the manufacturer's instructions. Microarray experiments were performed using Mouse Genome 430 2.0 Arrays (Affymetrix).

Project description:Adipose tissue dysfunction is closely associated with the development and progression of nonalcoholic fatty liver disease (NAFLD). Recent studies have implied an important role of prohibitin-1 (PHB1) in adipose tissue function. In the current study, we aimed to explore the function of adipocyte PHB1 in the development and progression of NAFLD. The PHB1 protein levels in adipose tissues were markedly decreased in mice fed a high-fat diet (HFD) compared to those fed a chow diet. To explore the function of adipocyte PHB1 in the progression of NAFLD, mice with adipocyte-specific (adipo) deletion of Phb1 (Phb1adipo-/- mice) were generated. Notably, Phb1adipo-/- mice did not develop obesity but displayed severe liver steatosis under HFD feeding. Compared to HFD-fed wild-type (WT) mice, HFD-fed Phb1adipo-/- mice displayed dramatically lower fat mass with significantly decreased levels of total adipose tissue inflammation, including macrophage and neutrophil number as well as the expression of inflammatory mediators. To our surprise, although liver steatosis in Phb1adipo-/- mice was much more severe, liver inflammation and fibrosis were similar to WT mice after HFD feeding. RNA sequencing analyses revealed that the interferon pathway was markedly suppressed while the bone morphogenetic protein 2 pathway was significantly up-regulated in the liver of HFD-fed Phb1adipo-/- mice compared with HFD-fed WT mice. Conclusion: HFD-fed Phb1adipo-/- mice display a subtype of the lean NAFLD phenotype with severe hepatic steatosis despite low adipose mass. This subtype of the lean NAFLD phenotype has similar inflammation and fibrosis as obese NAFLD in HFD-fed WT mice; this is partially due to reduced total adipose tissue inflammation and the hepatic interferon pathway.

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:To assess the effect of steatosis and oxidative stress on progression of liver fibrosis, we have employed whole genome microarray expression profiling as a discovery platform to identify genes that are related with oxidative stress- and steatosis-induced hepatic fibrogenesis. When wild type mice were fed high-fat/high-sucrose diet for 24 weeks, expression of 69 genes was changed more than 10-fold compared with wild type animals fed normal diet, 11 of which were categorized to lipid metabolic process. Moreover, expression of 208 genes showed more than 5-fold changes in Tet-mev-1 mice fed high-fat/high-sucrose diet compared with the same transgenic animals fed normal diet, and gene ontology analyses indicated significant changes in chemokine activity and chemokine receptor binding as well as defense and immune responses.

Project description:Using a C57BL6/J mouse model of diet-induced obesit,we observed that mannose supplementation of high fat diet (HFD)-fed mice prevents weight gain,lowers adiposity, reduces liver steatosis, and improves glucose tolerance and insulin sensitivity. We used microarrays to determine the gene expression pattern in epididymal fat frommice weaned on Normal diet (ND), HFD and HFD with mannose (HFDM)

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:In this study, we assessed the effect of acute oral administration of ellagic acid on metabolic parameters, oxidative stress and transcriptomic profiles in an inbred rodent model, carrying a variant of one of the metabolic syndrome-related genes, Zbtb16 (Zinc Finger And BTB Domain Containing 16). Over a period of three weeks, adult male rats of the SHR-Lx/k.o. strain were fed a high-fat diet accompanied with daily intragastric gavage of ellagic acid (50 mg/kg body weight; HFD-EA rats) or solvent only (HFD rats). At the end of the protocol, morphometric and metabolic parameters, including glucose tolerance test, serum lipid concentration and oxidative stress markers along with transcriptomic profile of liver, brown, and epididymal adipose tissues were assessed.

Project description:Obesity and insulin resistance are associated with oxidative stress, which may be implicated in their progression. The kinase JNK1 emerged as a promising drug target for the treatment of obesity and type-2 diabetes. However, JNK1 is a key mediator of the oxidative stress response, promoting either cell dead or survival depending on magnitude and context of its activation. Furthermore, JNK inactivation shortens lifespan in drosophila and c. elegans. To learn on the safety and efficacy of long-term JNK inhibition in vertebrates, we investigated mice lacking JNK1 (JNK1-/-) exposed over a long period to an obesogenic high-fat diet (HFD). JNK1-/- mice chronically fed an HFD developed more skin oxidative damage because of reduced catalase expression, but also showed sustained protection from obesity, adipose tissue inflammation, steatosis, and insulin resistance, paralleled by decreased oxidative damage in fat and liver. We conclude that JNK1 is a relatively safe drug target for obesity-related diseases. RNA was collected from liver, skin and epididymal fat tissues from JNK1 KO mice and WT mice fed in high fat diet. Each condition was run in quadruplicate
