ABSTRACT: C57BL/6 Male mice were treated with high fat diet at the age of 8 weeks and continue the diet for 16 weeks(4 mo) and then injected them with placebo/drug for 1 week before sacrifice. Their were sacrifised at the age of 6 months. Drug: Lira is used to reduce morbidity and mortality due to obesity and its effect on heart. 10 C57BL/6 Male mice under high fat diet for 16 weeks treated with either Placebo/drug were chosen for the microarray analysis. Heart from each mouse was disected and the left ventricle was used for TRNA extraction.
Project description:Two different mouse models of cardiac-specific ILK expression (ILKS343D and ILKR211A) were used to investigate the role of ILK in cardiac regeneration 4 groups with 3 mice (biological replicates) in each group with the total of 12 heart samples were used in this microarray experiment

Project description:Right ventricular samples were serially acquired during surgical repair of ventricular septal defect. Expression profiling revealed three patterns of gene expression: (1) increased expression above control levels within one hour of cardioplegic arrest, with further amplification during early reperfusion; (2) increased expression limited to the reperfusion phase; and (3) reduced expression during reperfusion. Experiment Overall Design: 4 replicates each: Experiment Overall Design: Stage2, End-ischemia Experiment Overall Design: Stage1, Immediately post-cardioplegic arrest Experiment Overall Design: Stage3, After 5 min. Reperfusion
Project description:Murine 3T3-L1 progenitor adipocytes cell cultures, treated and untreated (Control) with resveratrol before the induction of differentiation and the effects on adipogenesis and insulin signaling was investigated. Keywords: Treatment response 3 Replicates of treated and untreated (Control) cell cultures
Project description:Nocturnal home hemodialysis (NHD) [5 â 6 times a week, 6-8 hours per session] augments uremia clearance and is associated with an increase in hemoglobin level. We have used microarray to have a global image of the changes at the gene expression. Experiment Overall Design: Sixteen stable end-stage renal disease patients (age: 47 ñ 2 years; 9M) [mean ñ SEM] were studied. Total RNA (TRNA) was isolated from whole blood before and after 3 months of established NHD. Gene expression before and after NHD was acquired through hybridizations on Human HG-U133_PLUS2 GeneChip and genes with differential gene expression were identified.
Project description:To decipher the beneficial effects of Polyphenols on health, healthy volunteers were randomized into two groups and were submitted to either a red grape polyphenol rich extract supplemented diet (PP) or a placebo diet (PCB) during 8 weeks. Then they were submitted to a fructose load (3g/kg Fat Free Mass/day) during 7 days. Muscle biopsies were taken before the protocol, 8 weeks after PP or PCB diet and after the 7 days fructose load. We have employed whole genome microarray expression profiling as a discovery platform to identify genes regulated by fructose and to identify the mechanism of action of Polyphenols. Healthy volunteers were randomized into two groups and were submitted to either a red grape polyphenol rich extract supplemented diet (PP) or a placebo diet (PCB) during 8 weeks. Then they were submitted to a fructose load (3g/kg Fat Free Mass/day) during 7 days. Muscle biopsies were taken before the protocol, 8 weeks after PP or PCB diet and after the 7 days fructose load. We have employed whole genome microarray expression profiling as a discovery platform to identify genes regulated by fructose and to identify the mechanism of action of Polyphenols. Ten biological replicates were processed for PP diet, nine for PCB diet.
Project description:Lean male mice were fed a high fat diet (HFD, lard 24% w/w) for 16 weeks. At 9 weeks, when all hallmarks of prediabetes were established, groups of mice were treated with drug (rosiglitazone, pioglitazone, T0901317, or salicylate) for another 7 weeks together with the high fat diet. An additional group was switched back to a chow diet (dietary lifestyle intervention) after the first 9 weeks of high fat diet. All groups were compared to a control group receiving HFD alone and to a reference group fed chow (baseline reference) for the entire experimental period (16 weeks).

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).
