Resveratrol, a natural polyphenol abundant in grapes and red wine, has been reported to exert numerous beneficial health effects. Among others, acute neuroprotective effects of resveratrol have been described in several models of neurodegeneration, both in vitro and in vivo. In the present study we examined the neuroprotective effects of long-term dietary supplementation with resveratrol in mic...
Resveratrol (3,4’,5 tri-hydroxystilbene) is a plant phytoalexin produced in massive amount in grapevine skin in response to stress such as UV, phytosanitary treatment, and mostly following infection by Bothrytis cinerea. In this later case, the production of resveratrol inhibits the proliferation of the pathogen, thereby acting as a natural antifungal. Many experimental studies have reported in...
The thick ascending limb of the loop of Henle reabsorbs 30% of the NaCl filtered through the glomerulus. Nitric oxide (NO) produced by NO synthase 3 (NOS3) inhibits NaCl absorption by this segment. Resveratrol, a polyphenol, has beneficial cardiovascular and renal effects, many of which are mediated by NO. Resveratrol increases intracellular Ca2+ (Cai) and AMP kinase (AMPK) and NAD-dependent de...
Resveratrol is known to be a naturally produced polyphenol that is able to reduce cell proliferation in several types of cancer cells and adipocytes. However, the antiproliferative effects of resveratrol on the growth of human sebocytes are not yet clear. In the present study, we investigated possible cellular pathways associated with these growth inhibitory effects on human SZ95 sebocytes. Our...
Previous research has shown that resveratrol can increase cerebral blood flow (CBF) in the absence of improved cognitive performance in healthy, young human subjects during the performance of cognitively demanding tasks. This lack of cognitive effects may be due to low bioavailability and, in turn, reduced bioefficacy of resveratrol in vivo. Piperine can alter polyphenol pharmacokinetics, but p...
Epidemiological studies correlate moderate red wine consumption to reduced incidence of cardiovascular disease. Resveratrol is a polyphenolic compound in red wine that has cardioprotective effects in rodents. Although endothelial cell (EC) studies indicate that micromolar resveratrol has diverse biological activities, these concentrations are not physiologically relevant because human oral inge...
PURPOSE Resveratrol is a red wine polyphenol that causes vasorelaxation, which could be of interest in the treatment or prevention of eye diseases with an impaired blood flow. In this study, the vasorelaxant capacity of resveratrol (cis and trans) on bovine retinal arteries, its vasorelaxing mechanism, and its influence on the relaxation induced by the retinal relaxing factor (RRF) were examine...
Incidence of diabetic cardiomyopathy (DCM) is associated with increased mortality in diabetic patients. Mitochondrial dysfunction has been indicated to play a key role in the pathogenesis and development of diabetic cardiomyopathy. Accumulating evidence suggests that resveratrol, a polyphenol, exerts cardiovascular protective effects. In this study, we aimed to explore the effects of chronic re...
BACKGROUND AND PURPOSE Recent studies have shown that resveratrol increased endothelial progenitor cells (EPCs) numbers and functional activity. However, the mechanisms remain to be determined. Previous studies have demonstrated that increased EPC numbers and activity were associated with the inhibition of EPC senescence, which involves activation of telomerase. Therefore, we investigated wheth...
Resveratrol is known to improve functional recovery after spinal cord injury, but the exact mechanism involved is yet unclear. The aim of this study was to clarify whether resveratrol can exert neuroprotective effects via activating neuronal autophagic flux, in view of the underlying role of the autophagic flux mediated by resveratrol on neuronal apoptosis after spinal cord injury, and identify...
