Resveratol

BACKGROUND: Traumatic brain injury (TBI) is the damage to the brain caused by external blow or jolt to the head or body. TBI secondarily induces cell damage in the hippocampus. This study aimed to investigate effects of resveratrol treatment histological examination and nuclear factor kappa B (NFκB) expression in hippocampus after TBI. MATERIALS AND METHODS: Twenty-four rats were assigned to three groups: sham, TBI and TBI+Resveratol. TBI was conducted by dropping a 50-g weight from a 1-meter height from a tube to the head of animals...

UNLABELLED: Parkinson's disease (PD) is primarily the second most common neurological disorder, caused by the degeneration of dopaminergic neurons in the midbrain, which is primarily responsible for the onset of the disease. The major challenge faced in PD is the Blood Brain Barrier (BBB) which doesn't allow the delivery of therapeutics to the targeted locations. To solve the issue, lipid nano-systems have been used for precisely targeted delivery of therapeutic compounds for anti-PD therapy...

In this study, the black fertile (BSs) and the red unfertile seeds (RSs) of the Greek endemic Paeonia clusii subsp. rhodia (Stearn) Tzanoud were studied for the first time.

We aimed to design novel biocompatible nanocomposites containing natural antioxidant, resveratrol or curcumin and ZIF-8/mesoporous silica...

Hyperinflammation is related to the development of COVID-19. Resveratrol is considered an anti-inflammatory and antiviral agent. Herein, we used a network pharmacological approach and bioinformatic gene analysis to explore the pharmacological mechanism of Resveratrol in COVID-19 therapy. Potential targets of Resveratrol were obtained from public databases. SARS-CoV-2 differentially expressed genes (DEGs) were screened out via bioinformatic analysis Gene Expression Omnibus (GEO) datasets GSE147507, followed by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis; then, protein-protein interaction network was constructed...

Resveratol (RES) and its natural precursor polydatin (PD) are polyphenols that may display a broad variety of beneficial effects including anti-inflammatory properties. This study aimed to investigate the role of RES and PD in the inflammatory process induced by monosodium urate (MSU) and calcium pyrophosphate (CPP) crystals in vitro. A monocytic cell line (THP-1) was primed for 3 hours with phorbol myristate acetate (100 ng/mL) and stimulated with synthetic MSU (0.05 mg/mL) and CPP (0.025 mg/mL) crystals. RES and PD were added to cultures concurrently with the crystals, or as 2-hour pretreatment...

BACKGROUND: Resveratrol, a kind of polyphenol, has the potential to activate the longevity gene in several cells, in the same manner as calorie restriction. We investigated the effect of resveratrol and ω-3-line polyunsaturated fatty acid on surtuin 1 (SIRT1) gene expression in human monocytes (THP1) cells. MATERIALS AND METHODS: We examined the gene expression of THP1 cells using real-time polymerase chain reaction and Western blotting analysis. Resveratol, eicosapentaenoic acid (EPA) and docosahexaeanoic acid (DHA) as n-3 polyunsaturated fatty acid were added on THP1 cells...

Resveratrol (RV) is a natural polyphenol compound with a wide range of activities, including inhibition of human bladder cancer (HBC) cell growth. Because RV is rapidly metabolized and has poor bioavailability, it is unclear whether the antitumor activity is due to RV or its metabolites. We therefore used liquid chromatography-mass spectroscopy, qRT-PCR, immunocytochemistry and western blotting to evaluate the metabolic profile and biotransformation of RV in the T24 and EJ HBC cell lines. Both T24 and EJ cells generated the same RV metabolite, RV monosulfate (RVS), and both exhibited upregulation of the RV-associated metabolic enzyme SULT1A1 (sulfotransferase)...

Combining metformin with exercise has been proposed to improve glucose homeostasis. However, we primarily discuss evidence suggesting that metformin and other pharmacological agents/dietary supplements (e.g., statins, resveratol, or antioxidants) may in fact oppose exercise-induced benefits on insulin sensitivity and cardiometabolic health. We explore the novel hypothesis that attenuation of oxidative stress from exercise by these exogenous compounds blunts metabolic adaptation.

In addition to thousands of research papers related to resveratrol (RSV), approximately 300 review articles have been published. Earlier research tended to focus on pharmacological activities of RSV related to cardiovascular systems, inflammation, and carcinogenesis/cancer development. More recently, the horizon has been broadened by exploring the potential effect of RSV on the aging process, diabetes, neurological dysfunction, etc. Herein, we primarily focus on the in vivo pharmacological effects of RSV reported over the past 5 years (2009-2014)...

A number of small molecules with the ability to extend the lifespan of multiple organisms have recently been discovered. Resveratrol, amongst the most prominent of these, has gained widespread attention due to its ability to extend the lifespan of yeast, worms, and flies, and its ability to protect against age-related diseases such as cancer, Alzheimer's, and diabetes in mammals. In this review, we discuss the origins and molecular targets of resveratrol and provide an overview of its effects on the lifespan of simple model organisms and mammals...

Throughout the Western world obesity prevalence is steadily increasing, and associated metabolic co-morbidities are projected to rise during the years to come. As weight loss and weight maintenance remains a major problem, new strategies to protect against obesity-related morbidity are needed. There is a clear association between obesity, low-grade inflammation and obesity-associated diseases, thus, the development of new anti-inflammatory substances is urgently needed as these may ultimately pave the way for novel treatments of obesity and lifestyle-related diseases...

There is an increasing need for novel preventive and therapeutic strategies to combat obesity and related metabolic disorders. In this respect, the natural polyphenol resveratrol has attracted significant interest. Animal studies indicate that resveratrol mimics the effects of calorie restriction via activation of sirtuin 1 (SIRT1). SIRT1 is an important player in the regulation of cellular energy homeostasis and mitochondrial biogenesis. Rodent studies have shown beneficial effects of resveratrol supplementation on mitochondrial function, glucose metabolism, body composition and liver fat accumulation...

Diabetes mellitus is a serious disease affecting about 5% of people worldwide. Diabetes is characterized by hyperglycemia and impairment in insulin secretion and/or action. Moreover, diabetes is associated with metabolic abnormalities and serious complications. Resveratrol is a natural, biologically active polyphenol present in different plant species and known to have numerous health-promoting effects in both animals and humans. Anti-diabetic action of resveratrol has been extensively studied in animal models and in diabetic humans...

Osteoporosis is a major public health issue that is expected to rise as the global population ages. Resveratrol (RES) is a plant polyphenol with various anti-aging properties. RES treatment of bone cells results in protective effects, but dose translation from in vitro studies to clinically relevant doses is limited since bioavailability is not taken into account. The aims of this review is to evaluate in vivo evidence for a role of RES supplementation in promoting bone health to reduced osteoporosis risk and potential mechanisms of action...

Low capacity runner (LCR) rats have been developed by divergent artificial selection for treadmill endurance capacity to explore an aerobic biology-disease connection. The beneficial effects of resveratrol supplementation have been demonstrated in endurance running. In this study it was examined whether 12 weeks of treadmill exercise training and/or resveratrol can retrieve the low running performance of the LCR and impact mitochondrial biogenesis and quality control. Resveratrol regressed running performance in trained LCR (p<0...

INTRODUCTION: Resveratrol is a plant-derived polyphenol suggested to have many beneficial health effects, including antioxidant, anti-inflammatory, anti-proliferative, proapoptotic, and anti-angiogenic. It is even specu- lated that uptake of resveratrol by red wine consumption could be behind the so-called French paradox the lower incidence of cardiovascular diseases in the French population. These properties, together with good absorption and tolerance, would make it an attractive agent in prostatic diseases, especially in cancer prevention and treatment...

OBJECTIVE: To study the effect of resveratol on ischemia reperfusion-induced cardiocyte apoptosis and its relationship with PI3K-Akt signaling pathway. METHOD: Fifty male SD rats were divided randomly into five groups: the control group (SH group), the ischemia reperfusion group (I/R group), the resveratol pretreatment group (Res group), the resveratol pretreatment + wortmannin group (Res +Wom group) and the ischemia reperfusion + wortmannin group (I/R + Wom group)...

Glomerular podocytes are highly specialized epithelial cells whose injury in glomerular diseases causes proteinuria. Since mitochondrial dysfunction is an early event in podocyte injury, we tested whether a major regulator of oxidative metabolism and mitochondrial function, the transcriptional coactivator peroxisome proliferator-activated receptor-γ coactivator 1α (PGC-1α), affects podocyte damage. Aldosterone-induced injury decreased PGC-1α expression, and induced mitochondrial and podocyte damage in dose- and time-dependent manners...

To observe the effect of resveratol on cartilage, chondrocyte apoptosis, and nitric oxide in experimental osteoarthritis (OA) of rabbit and to study the mechanism of resveratol in the treatment of osteoarthritis. Thirty New Zealand rabbits were randomly divided into 5 groups: group A (normal control group), group B (model control group), group C (resveratrol intervention high-dosage group), group D (resveratrol intervention middle dosage group), and group E (resveratrol intervention low-dosage group). The model of OA of the knee was established using Hulth technique in groups B, C, D, and E...
