Project description:We characterized the insulin sensitivity and multi-tissue gene expression profiles of lean and insulin resistant, obese Zucker rats untreated or treated with one of four PPARγ ligands (pioglitazone, rosiglitazone, troglitazone, and AG035029). We analyzed the transcriptional profiles of adipose tissue, skeletal muscle, and liver from the rats and determined whether ligand insulin-sensitizing potency was related to ligand-induced alteration of functional pathways. Ligand treatments improved insulin sensitivity in obese rats, albeit to varying degrees. Male Zucker fatty (fa/fa) and lean (fa/+) rats (Charles River, Wilmington, MA) were received at 6 weeks of age. Fatty rats were weight-matched upon arrival and randomly divided into one of five experimental groups. The fatty rat groups varied by the type of chow they were fed - normal chow alone or with a PPARγ ligand admixture: normal chow (fatty control, FC), rosiglitazone-treated (Rosi), pioglitazone-treated (Pio), troglitazone-treated (Tro), or AG035029-treated (AG). Lean control (LC) rats were all fed normal chow. Rats groups were maintained on the diets for 21 days. Adipose tissue (epididymal), skeletal muscle (gastrocnemius), and liver were harvested from lean (LC) and insulin resistant, obese Zucker rats untreated (FC) or treated with one of four PPARγ ligands (pioglitazone [Pio], rosiglitazone [Rosi], troglitazone [Tro], and AG035029 [AG]).

Project description:Thiazolidinediones increase tissue insulin sensitivity and are protective against worsening of nephropathy and hypertension in diabetes. Mechanisms underlying protection at the renal level likely involve a variety of unknown changes in gene expression. We examined kidney gene expression in obese and lean Zucker rats in response to rosiglitazone (Avandia®), a peroxisome proliferator activated receptor (gamma-subtype) agonist. Lean and obese Zucker rats were treated with either control chow or chow with added rosiglitazone (3 mg/kg�bw) for 12 weeks (n = 3/group). Total kidney mRNA expression was evaluated using the Affymetrix Rat Genome 230 2.0 GeneChip. 903 probe sets were significantly (P < 0.05) altered with at least 1.5-fold changes between groups. In untreated obese rats, 300 probe sets were increased and 244 decreased, relative to lean. Increased genes included the β-subunit of the epithelial sodium channel (ENaC), the thiazide-sensitive Na-Cl cotransporter, and aquaporin 3. Decreased genes included angiotensin converting enzyme, type 1 (ACE1). FatiGO analysis showed that the highest number of altered genes between lean and obese belonged to the categories: ion binding, hydrolase activity, and protein binding. RGZ increased expression of uncoupling protein 1 (UCP1), CD36, and fatty acid binding protein 4 (FAbp4) in both lean and obese rats. In obese rats, 33 genes were normalized by RGZ (no longer different from lean) including ACE1, fatty acid synthase (Fasn), and stearoyl-coenzyme A desaturase 2 (Scd2). Ingenuity Pathways System analysis of genes upregulated by RGZ in obese rats revealed two major nodes affected: PPAR-gamma and tumor necrosis factor alpha (TNF-alpha). Experiment Overall Design: Twelve male Zucker rats (6 Lean and 6 Obese) were used in the study. Three rats from each body type were fed either with control diet (ground chow diet) or control diet with rosiglitazone (3 mg/kg body weight). The rats were weighed weekly and fed diets and recieved water ad libitum for 12 weeks.

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:De novo lipogenesis (DNL) has been implicated in the development and progression of hepatic liver steatosis. Hepatic DNL is strongly influenced by dietary macronutrient composition with diets high in carbohydrate increasing DNL and diets high in fat decreasing DNL. The enzymes in the core DNL pathway have been well characterised however less is known about proteins that play accessory or regulatory roles in DNL. In the current study, we associate measured rates of hepatic DNL and liver fat content with abundance of liver proteins from liquid chromatography mass spectrometry in mice to identify known and uncharacterised proteins that may have a role in DNL. Male C57BL/6J mice were fed either a standard chow diet a semi-purified high starch diet or a high fat diet. Both semi-purified diets resulted in increased body weight, fat mass and liver triglyceride content compared to chow-fed mice while hepatic DNL was increased in the high starch fed mice and decreased in the high fat fed mice. Proteomic analysis was carried out on the livers of these mice and proteins were identified that associated with either the rate of DNL or triglyceride content in the liver. There was no overlap between DNL and triglyceride associated proteins. We identify novel proteins associated with DNL that are involved in taurine metabolism, which suggests a link between these pathways. Further analysis identified proteins that are differentially regulated when comparing a non-purified chow diet to either of the semi-purified diets to provide a set of proteins that are regulated by the degree of dietary complexity alone. Finally, we compared the liver proteome between 4 week-fed and 30-week diet-fed mice and found remarkable similarity suggesting that the majority of diet-regulated proteins change early in response to differing dietary components.

Project description:The satellite cell of skeletal muscle provides a paradigm for quiescent and activated tissue stem cell states. We have carried out transcriptome analyses by comparing satellite cells from adult skeletal muscles, where they are mainly quiescent, with cells from growing muscles, regenerating (mdx) muscles, or with cells in culture, where they are activated. Our study gives new insights into the satellite cell biology during activation and in respect with its niche. We used microarrays to study the global programme of gene expression underlying adult satellite cell quiescence compared to activation states and to identify distinct classes of up-regulated genes in these two different states Skeletal muscle satellite cells were isolated by flow cytrometry using the GFP fluorescence marker from Pax3GFP/+ mice skeletal muscle. The transcriptome of quiescent satellite cells from adult Pax3GFP/+ muscle was compared to the transcriptome of activated satellite cells obtained from three different samples: 1) regenerating Pax3GFP/+:mdx/mdx muscle (Ad.mdx) , 2) growing 1 week old Pax3GFP/+ muscle (1wk), and 3) adult Pax3GFP/+ cells after 3 days in culture (Ad.cult).
