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:Most commonly used models of non-alcoholic steatohepatitis (NASH) are diets based on specific gene knockouts or represent extreme manipulations of diet. We have examined the effects of modest increased caloric intake and high dietary unsaturated fat content on the development of NASH in male rats using a model in which overfeeding is accomplished via intragastric infusion of liquid diets as a part of total enteral nutrition. Male Sprague dawley rats were fed diets 5% corn oil containing diets at 187 Kcal/kg3/4/d or fed 70% corn oil containing diets at 220 Kcal/kg3/4/d for a period of 3 weeks. Hepatic gene expression were assessed at the end of the study. Our results indicate that overfeeding of high unsaturated fat diets leads to pathological, endocrine and metabolic changes characteristic of NASH patients and is associated with increased oxidative stress and TNF-a.

Project description:High fat diets (HFDs) are linked to several diseases including obesity, diabetes, insulin resistance, fatty liver, and susceptibility to inflammatory bowel disease (IBD) in both mouse and humans. RNA-seq from male mice (C57BL/6N) fed Vivarium Chow (VIV) or any one of three high fat diets (40% kcal fat) (SO+CO, PL+CO, CO) for 24 weeks was performed on four segments of the intestinal tract (Duodenum, Jejunum, Terminal Ileum and Proximal Colon).

Project description:A diet rich in nucleic acids and protamin protein, termed as nucleoprotein was used for the study. Mice were fed with NP diets for 4 weeks followed by removal of the liver and spleen. Total RNA extracted from livers and spleens was pooled in each group (low NP or LNP-control, and 1.2% NP-treatment, diets), prior to DNA microarray analysis (Agilent mouse whole genome 4 x 44K). Results revealed 1373 & 3386 up (>1.5 fold)- and down (<0.75 fold)-regulated genes in the liver, and 252 & 1838 up- and down-regulated genes in the spleen, respectively following 1.2%NP diet. Analysis of genes related to NP diets will be discussed.

Project description:Obesity has been shown to increase risk for cardiovascular disease and type-2 diabetes. In addition, it has been implicated in aggravation of neurological conditions such as Alzheimer’s. In the model organism Drosophila melanogaster, a physiological state mimicking diet-induced obesity can be induced by subjecting fruit flies to a solid medium disproportionately higher in sugar than protein (HSD) or that has been supplemented with a rich source of saturated fat (HFD). These flies can exhibit increased circulating glucose levels, increased triglyceride content, insulin-like peptide resistance, and behavior indicative of neurological decline, such as decreased climbing ability. We subjected Oregon-R-C flies to variants of the HSD, HFD, or normal (control) diet (ND), followed by a total RNA extraction from fly heads of each diet group for the purpose of Poly-A selected RNA-Sequencing. We targeted at least 50 million paired-end, stranded reads of 75 basepairs in size, and analyzed 4 biological replicates per dietary condition. Our objective was to identify the effects of obesogenic diets on transcriptome patterns, how they differed between obesogenic diets, and identify genes that may relate to pathogenesis accompanying an obesity-like state. Functional annotation and enrichment analysis among genes whose expression was significantly affected by the obesogenic diets indicated an overrepresentation of genes associated with immunity, metabolism, and hemocyanin in the HFD group, and CHK, cell cycle activity, and DNA binding and transcription in the HSD group. Heat map representation of genes affected by both diets illustrated a large fraction of differentially expressed genes between the two diet groups. Diets high in sugar and diets high in fat both have notableeffects on the Drosophila transcriptome in head tissue. The impacted genes, and how they may relate to pathogenesis in the Drosophila obesity-like state, warrant further experimental investigation. Our results also indicate differences in the effects of the HFD and HSD on expression profiles in head tissue of Oregon-R-C flies, despite the reportedly similar phenotypic impacts of the diets.

Project description:Hybrid sturgeon, an ancient fish, has great economic and nutritional value as a source of caviar. Although significant differences exist in the female reproductive capacity under artificial breeding conditions, differential gene expression associated to domesticated female reproductive capacity have never been investigated. In this study, we conducted reference genome-based transcriptome sequencing of 16 individuals from high-yield (H) and low-yield (L) populations, respectively.
