Project description:To systemically evaluate the comprehensive alterations under the supplements of quercetin and/or resveratrol in high fat diet (HFD) fed mice, we have employed whole genome microarray expression profiling as a discovery platform to identify genes that differentially altered by different treatments. Gene expression profiles were significantly altered by long term HFD feeding. However, quercetin, resveratrol and their combination could effectively attenuate this alteration. Especially, combination use of quercetin and resveratrol showed more signifcant benefits on the changes of genes, involved in metabolic disorders, induced by HFD, which revealed a synergistic effect of quercetin and resveratrol supplementation in high fat diet fed mice.

Project description:To determine the effect of resveratrol or metformin on high fat diet induced insulin resistance mice and elucidate their underlying mechanisms, we conducted a high-throughput sequencing analysis on epididymal fat tissue. LncRNAs and mRNAs were quantified and differentially expressed genes were identified, providing a potential gene signature for pharmacological mechanism of resveratrol and metformin.

Project description:Recent discovery reveals HFD insult can cause insulin resistance very rapidly, but the underlying mechanism is still not well understood. We performed a short term experiment in a Diet Induced Insulin resistance mouse model. Objective: Insulin resistance (IR) is one of the earliest predictors of type 2 diabetes. However, diagnosis of IR is limited. High fat fed mouse models provide key insights into IR. We hypothesized that early features of IR are associated with persistent changes in gene expression (GE) and endeavoured to (a) develop novel methods for improving signal:noise in analysis of human GE using mouse models; (b) identify a GE motif that accurately diagnoses IR in humans; and (c) identify novel biology associated with IR in humans. Methods: We integrated human muscle GE data with longitudinal mouse GE data and developed an unbiased three-level cross-species analysis platform (single-gene, gene-set and networks) to generate a gene expression motif (GEM) indicative of IR. A logistic regression classification model validated GEM in 3 independent human datasets (n =115). Results: This GEM of 93 genes substantially improved diagnosis of IR compared to routine clinical measures across multiple independent datasets. Individuals misclassified by GEM possessed other metabolic features raising the possibility that they represent a separate metabolic subclass. The GEM was enriched in pathways previously implicated in insulin action and revealed novel associations between β-catenin and Jak1 and IR. Functional analyses using small molecule inhibitors showed an important role for these proteins in insulin action. Conclusions: This study shows that systems approaches for identifying molecular signatures provides a powerful way to stratify individuals into discrete metabolic groups. Moreover, we speculate that the β-catenin pathway may represent a novel biomarker for IR in humans that warrant future investigation. Comparison of gene expression in muscle tissue during High Fat Diet (HFD) time course (day 5 and day 42). Chow diet will serve as control for HFD. 4 samples per group serve as experimental replicates.

Project description:Maternal health and diet can have important consequences for offspring nutrition and metabolic health. Signals are communicated from the mother to the infant during lactation through milk via macronutrients, hormones and bioactive molecules. In this study we designed experiments to probe the mother-milk-infant triad in the condition of normal maternal health and upon exposure to high fat diet (HFD) with or without concurrent metformin exposure. We examined maternal characteristics, milk composition and offspring metabolic parameters on postnatal day 16, prior to offspring beginning to wean. We found that lactational HFD increased maternal adipose tissue, mammary gland adipocytes, and altered milk lipid composition causing a higher amount of n-6 long chain fatty acids and lower n-3. Offspring of HFD dams were heavier with more body fat during suckling. Metformin exposure decreased maternal glucose and several amino acids. Offspring of met dams were smaller during suckling. Gene expression in the lactating mammary glands was impacted to a greater extent by metformin but both metformin and HFD altered genes related to muscle contraction, indicating that these genes may be more susceptible to lactational stressors. Our study demonstrates the impact of common maternal exposures during lactation on milk composition, mammary gland function and offspring growth with metformin having little capacity to recuse from the effects of a maternal HFD during lactation.

Project description:Eight weeks after C57BL / 6J mice fed a high-fat diet (HFD), the degree of insulin resistance was assessed by intraperitoneal glucose tolerance test (IPGTT) and the insulin resistance model was successfully established. Mice were then treated with resveratrol and metformin for 6 weeks and blood and liver tissue samples were collected. Blood biochemical parameters were determined by kit, protein expression of hepatic insulin signaling pathway mRNA and mRNA was determined by Western blot and real-time polymerase chain reaction, and histomorphological changes were observed by histological staining. Mouse liver tissue samples were detected by high-throughput sequencing technology to obtain differential lncRNA expression profiles. Further differentially expressed genes were analyzed using bioinformatics techniques.

Project description:Resveratrol delays age-related deterioration and mimics transcriptional aspects of dietary restriction without extending lifespan A small molecule that safely mimics the ability of dietary restriction (DR) to delay age-related diseases in laboratory animals is greatly sought after. We and others have shown that resveratrol mimics effects of DR in lower organisms. In mice, we find that resveratrol induces gene expression patterns in multiple tissues that parallel those induced by DR and every-other-day feeding. Moreover, resveratrol-fed elderly mice shows a marked reduction in signs of aging including reduced albuminuria, decreased inflammation and apoptosis in the vascular endothelium, increased aortic elasticity, greater motor coordination, reduced cataract formation, and preserved bone mineral density. However, mice fed a standard diet did not live longer when treated with resveratrol beginning at mid-life. Our findings indicate that resveratrol treatment has a range of beneficial effects in mice but does not increase the longevity of ad libitum-fed animals when started mid-life.

Project description:Obesity is associated with a chronic, low-grade, systemic inflammation that may contribute to the development of insulin resistance and type 2 diabetes. Resveratrol, a natural compound with anti-inflammatory properties, is shown to improve glucose tolerance and insulin sensitivity in obese mice and humans. Here we tested the effect of a 2-year resveratrol administration on the pro-inflammatory profile and insulin resistance caused by a high-fat, high-sugar (HFS) diet in white adipose tissue (WAT) from rhesus monkeys. Eighty mg/day of resveratrol for 12-month followed by 480 mg/day for the second year decreased adipocyte size, increased sirtuin 1 expression, decreased NF-kB activation and improved insulin sensitivity in visceral but not subcutaneous WAT from HFS-fed animals. These effects were reproduced in 3T3-L1 adipocytes cultured in media supplemented with serum from monkeys fed HFS +/- resveratrol diets. In conclusion, chronic administration of resveratrol exerts beneficial metabolic and inflammatory adaptations in visceral WAT from diet-induced obese monkeys.
