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: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:The resveratrol-producing rice (Oryza sativa L.) inbred line, Iksan 526 (I.526), developed by the expression of the groundnut (Arachis hypogaea) resveratrol synthase 3 (AhRS3) gene in the japonica rice cultivar Dongjin, accumulated both resveratrol and its glucoside, piceid, in leaves and seeds. Especially, ultra-performance liquid chromatography (UPLC) analysis revealed that the biosynthesis of piceid reached peak levels at 20 days after heading (DAH) seeds. To investigate endogenous piceid biosynthesis genes (UGTs), total RNA samples of 20 DAH seeds was used for RNA-seq.

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. Male C57BL/6NIA mice at 11 months of age were maintained on a standard purified mouse diet (AIN-93G) for one month prior to the start of the experiment. Beginning at one year of age, SD and EOD groups were fed a standard AIN-93G diet or AIN-93G plus 0.01% or 0.04% resveratrol for the duration of the study. Three separate groups were placed on an HC diet (AIN-93G modified by the addition of hydrogenated coconut oil to provide 60% of calories from fat) or HC + 0.01% or 0.04% resveratrol 6 weeks later and remained on those diets throughout the study. SD and HC mice were fed ad libitum. EOD mice were fed ad libitum on alternate days then moved to a separate cage without food for 24 h. Food intake and body weight were measured on a weekly basis for the duration of the study.

Project description:Resveratrol in high doses has been shown to extend lifespan in some studies in invertebrates and to prevent early mortality in mice fed a high-fat diet. We fed mice from middle age (14-months) to old age (30-months) either a control diet, a low dose of resveratrol (4.9 mg kg-1 day-1), or a calorie restricted (CR) diet and examined genome-wide transcriptional profiles. We report a striking transcriptional overlap of CR and resveratrol in heart, skeletal muscle and brain. Both dietary interventions inhibit gene expression profiles associated with cardiac and skeletal muscle aging. Gene expression profiling suggests that both CR and resveratrol may retard some aspects of aging through alterations in chromatin structure and transcription. Resveratrol, at doses that can be readily achieved in humans, fulfills the definition of a dietary compound that mimics some aspects of CR. Keywords: aging intervention study

Project description:Chronic high-fat/high-sugar (HFS) feeding is linked to the development of insulin resistance as well as arterial wall and adipose tissue inflammation in nonhuman primates. These changes are significantly reduced when the animals are fed a HFS diet supplemented with resveratrol (RSV) for two years. Herein, we evaluated the occurrence of cerebral cortex injury in these HFS-fed middle-aged male rhesus monkeys and investigated the possibility of brain protection by RSV treatment. HFS caused a reduction in capillary density in the cerebral cortex that was preempted by RSV supplementation. The patterns of cDNA microarray analysis revealed upregulation of markers of oxidative stress, inflammation and apoptosis in the cortical cortex of HFS-fed monkeys, which was reversed by RSV. The underlying mechanism of RSV action included its ability to prevent the HFS-mediated NF-kappa-B activation and loss in mitochondrial aldehyde dehydrogenase 2 expression. We conclude that RSV may confer neuroprotection against HFS-mediated cerebral vascular dysfunction and activation of inflammatory pathways.

Project description:The polyphenol resveratrol has anti-inflammatory effects in various cells, tissues, animals and human settings of low-grade inflammation. Psoriasis is a disease of both localized and systemic low-grade inflammation. The Sirtuin1 enzyme thought to mediate the effects of resveratrol is present in skin and resveratrol is known to downregulate NF-κB; a major contributor in the development of psoriasis. Consequently we investigated whether resveratrol has an effect on an Imiquimod induced psoriasis-like skin inflammation in mice and sought to identify candidate genes, pathways and interleukins mediating the observed effects. The study consisted of three treatment groups: A control group, an Imiquimod group and an Imiquimod+resveratrol group. Psoriasis severity was assessed using elements of the Psoriasis Area Severity Index, actual skin thickness measurements, and histological examination. We performed an RNA microarray from lesional skin and afterwards Ingenuity pathway analysis to identify affected signalling pathways. Our microarray was compared to a previously deposited microarray to determine if gene changes were psoriasis-like, and to a human microarray to determine if findings could be relevant in a human setting. Imiquimod treatment induced a psoriasis-like skin inflammation. Resveratrol significantly diminished the severity of the psoriasis-like skin inflammation. The RNA microarray revealed a psoriasis-like gene expression-profile in the Imiquimod treated group, and highlighted several resveratrol dependent changes in relevant genes, such as increased expression of genes associated with retinoic acid stimulation and reduced expression of genes involved in IL-17 dependent pathways (e.g.IL-17A, IL-17F,IL-23p19 ). Quantitative PCR confirmed a resveratrol dependent decrease in mRNA levels of IL-17A and IL-19; both central in developing psoriasis. In conclusion, resveratrol ameliorates psoriasis, and changes in expression of retinoic acid stimulated genes, IL-17 signalling pathways, IL-17A and IL-19 mRNA levels in a beneficial manner suggests it might have a role in the treatment of psoriasis and should be explored further in a human setting.

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.
