Project description:Transcriptional profiling of mouse white adipose tissues The objective of this study is to explore the relationship between vitamin B6 activity and chronic inflammation of white adipose tissue in mice fed a high-fat diet. Twenty-four CD-1 mice were divided into two groups (n = 12) and fed either a 1 mg pyridoxine (PN) HCl /kg diet or a 35 mg PN HCl /kg diet for 8 weeks. We isolated total RNA from epididymal white adipose tissue of each group and compared gene expression profiles by DNA microarray data analysis.

Project description:C57BL/6J mice were from The Jackson Laboratory (Maine, USA) and were housed/caged and fed a standard chow diet until 6 weeks of age whereupon they were placed in one of 4 different dietary regimens for a period of 3 weeks prior to mating. Mice were housed under pathogen-free conditions of 21± 1°C, 40 to 60% humidity, and a 12 h-12 h light/dark cycle. The 4 diet regimens used in this study were: [1] ad lib Standard Chow (Control diet) with ad lib drinking water. [2] Ad lib Standard Chow, with ad lib drinking water containing 0.64 mg/ml (97 mg/Kg body weight) monosodium glutamate (MSG diet). [3] Ad lib Test Diet Purina 5001 with 20% 55-HFCS (5B4K, Purina, USA), and ad lib drinking water (HFCS diet). [4] Ad lib Purina 5001 with 20% 55-HFCS, and ad lib drinking water containing 0.64 mg/ml (97 mg/K body weight) monosodium glutamate (HFCS+MSG diet). See Table 1 for diet composition. Following mating, the 4 groups of dams were maintained on their respective diets throughout the gestation and nursing period. Male offspring used in these experiments were weighed, then weaned onto the same diets and maintained in this regimen until they reached either 16 or 32 weeks of age. Total RNA was prepared from the liver and visceral white adipose tissue (WAT) taken from 16-week-old mice in the 4 different diet groups using Qiagen RNeasy Kit (Qiagen USA) according to the manufacturers instructions and stored at -80 o C.<br>

Project description:We identified differentially expressed genes in epididymal white adipose tissue of high fat diet(HFD)-fed mice compared to low fat diet-fed mice using microarray analysis. Microarray analysis revealed that genes related to lipolysis, fatty acid metabolism, mitochondrial energy transduction, oxidation-reduction, insulin sensitivity, and skeletal system development were downregulated in HFD-fed mice, and genes associated with extracellular matrix (ECM) components, ECM remodeling, and inflammation were upregulated. The top 10 up- or downregulated genes include Acsm3, mt-Nd6, Fam13a, Cyp2e1, Rgs1, and Gpnmb, whose roles in obesity-associated adipose tissue deterioration are poorly understood. Total RNA of epididymal white adipose tissue was obtained from low fat diet (10 kcal% fat)- and high fat diet(45 kcal% fat)-fed mice and mRNA expression was measured using microarray analysis.

Project description:Purpose: To investigate the involvement of mTORC1 as a mediator of the actions of the PPARγ ligand rosiglitazone in subcutaneous inguinal white adipose tissue transcriptome; Methods: Mice bearing regulatory associated protein of mTOR (Raptor) deletion and therefore mTORC1 deficiency exclusively in adipocytes (adiponectin Cre recombinase) and littermate controls were fed a high-fat diet supplemented or not with the PPARγ agonist rosiglitazone (30 mg/kg/day) for 8 weeks and evaluated for inguinal white adipose tissue transcriptome (Rnaseq); Results: 3,2425 genes had their correspondent mRNA levels altered by either adipocyte Raptor deficiency or rosiglitazone administration or their combination. Among those, 408 genes modulated by rosiglitazone required mTORC1. Conclusion: PPARγ and mTORC1 are essential partners in the regulation of a cluster of genes in inguinal white adipose tissue.

Project description:SNPs affecting disease risk often reside in non-coding genomic regions. Here we show that SNPs are highly enriched at mouse strain-selective adipose tissue binding sites for PPARγ, a nuclear receptor for antidiabetic drugs. Many such SNPs alter binding motifs for PPARγ or cooperating factors, and functionally regulate nearby genes whose expression is strain-selective and imbalanced in heterozygous F1 mice. Moreover, genetically-determined binding of PPARγ accounts for mouse strain-specific transcriptional effects of TZD drugs, providing proof-of- concept for personalized medicine related to nuclear receptor genomic occupancy. In human fat, motif-altering SNPs cause differential PPARγ binding, provide a molecular mechanism for some expression quantitative trait loci, and are risk factors for dysmetabolic traits in genome- wide association studies. One PPARγ motif-altering SNP is associated with HDL levels and other metabolic syndrome parameters. Thus, natural genetic variation in PPARγ genomic occupancy determines individual disease risk and drug response. Comparison of 5 RNA-seq experiments between 2 strains of mice differing in diet and fat depot. One of the experiments was evaluation of the response to a drug Rosiglitazone. Our RNA-seq data comprises primarily of 4 main experiments: The first experiment consists of samples taken from 2 strains of mice and their F1 progeny The samples are all taken from the same depot and when the mice were fed the same chow diet The second experiment has 2 parts, the first one involves samples taken from the 2 strains from the same eWAT depot when they were kept on a Low Fat Diet (LFD) This first part serves as a control for the second one in which the mice were treated with a drug, rosiglitazone in conjunction with a LFD The third experiment consists of samples taken from mice being fed on LFD. The samples are taken from the eWAT depot for both the strains. The fourth experiment consists of samples taken from mice being fed on LFD. The samples are taken from the iWAT depot for both the strains. We also have a solitary sample from a GRO-seq experiment which was done on eWAT in a B6 strain of mice being fed a LFD eWAT: epididymal White Adipose Tissue iWAT: inguinal White Adipose Tissue LFD-12w: mice were fed a control low fat diet (Research Diet D12450B) chow: mice were fed standard rodent chow Diet LFD w/rosiglitazone: Drug rosiglitazone (Cayman Chemicals) was incorporated into low fat diet D12450B by Research Diets at 36mg/kg of diet. Mice received control low fat diet for 10 weeks (age 6-16 weeks), and the rosiglitazone-containing diet versus control diet for the final 2 weeks (until sacrifice at 18 weeks) LFD control for rosi: mice were fed a control low fat diet (Research Diet D12450B)

Project description:Gaining understanding of common complex diseases and their treatments are the main drivers for life sciences. As we show here, comprehensive protein set analyses offer new opportunities to decipher functional molecular networks of diseases and assess the efficacy and side-effects of treatments in vivo. Using mass spectrometry, we quantitatively detected several thousands of proteins and observed significant changes in protein pathways that were (dys-) regulated in diet-induced obesity mice. Analysis of the expression and post-translational modifications of proteins in various peripheral metabolic target tissues including adipose, heart, and liver tissue generated functional insights in the regulation of cell and tissue homeostasis during high-fat diet feeding and medication with two antidiabetic compounds. Protein set analyses singled out pathways for functional characterization, and indicated, for example, early-on potential cardiovascular complication of the diabetes drug rosiglitazone. In vivo protein set detection can provide new avenues for monitoring complex disease processes, and for evaluating preclinical drug candidates. Male C57BL/6 mice (age 6 wks) were fed for 12 weeks with high-fat diet (HFD) and than distributed into 3 groups. Mice were than fed over 3 weeks with HFD without compound ('HFD'), HFD with 4 mg/kg/d rosiglitazone ('HFD_RSG') or with 100 mg/kg/d amorfrutin 1 ('HFD_A1'). In parallel, mice were fed for 15 weeks with low-fat diet (LFD) as healthy control subjects. In addition, a group of mice was treated with 37 mg/kg/d amorfrutin 1 during the whole 15 weeks of HFD feeding ('HFD+A1prev'). Finally, visceral white adipose tissue (WAT) was harvested and RNA extracted. --> 2-4 biological replicates (2 mice per each replicate, RNA of 2 mice always pooled).

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).
