          Abstract

          Resumen Introducción y objetivos: el estrés oxidante se considera uno de los principales mecanismos de genotoxicidad y carcinogenicidad de los metales pesados. Por otra parte, el resveratrol posee propiedades antioxidantes y es uno de los polifenoles más estudiados debido a su gran variedad de efectos benéficos para la salud. Sin embargo, no hay revisiones sistemáticas de la literatura científica en las que se analicen los efectos del resveratrol sobre el estrés oxidante inducido por metales pesados. Métodos: en esta revisión se realizó una búsqueda de artículos mediante las bases de datos PubMed® y ScienceDirect® (1996-2018). Después de aplicar diversos filtros, se consideraron once investigaciones in vivo e in vitro en las que se estudiaron los efectos del resveratrol sobre el estrés oxidante inducido por el arsénico (As), el cadmio (Cd), el cobre (Cu), el cromo (Cr) y el hierro (Fe). Resultados: en la revisión se presenta un análisis de los efectos químicos del resveratrol sobre el estrés oxidante asociado a la exposición a compuestos metálicos. Se discute la interacción del resveratrol con la producción de especies reactivas de oxígeno (ERO) y el sistema antioxidante endógeno, y sus efectos sobre el daño del ADN. A partir de estos estudios se genera un diagrama que muestra las interacciones propuestas para el resveratrol, los metales pesados As, Cd, Cu, Cr y Fe, y el estrés oxidante. Conclusiones: los estudios analizados muestran que el resveratrol es capaz de modular el estrés oxidante generado por diferentes compuestos de metales pesados como As, Cd, Cu, Cr y Fe.

          Abstract Introduction and objectives: oxidative stress is considered one of the main mechanisms of genotoxicity and carcinogenicity of heavy metals. In contrast, resveratrol has antioxidant properties and is one of the most studied polyphenols due to its wide variety of beneficial health effects. However, there are no systematic reviews of the scientific literature in which the effects of resveratrol on oxidative stress induced by heavy metals are analyzed. Methods: in this review, articles were searched using the PubMed® and ScienceDirect® databases (1996-2018). After applying various filters, eleven in vivo and in vitro researches were considered, in which the effects of resveratrol on oxidative stress as induced by arsenic (As), cadmium (Cd), copper (Cu), chromium (Cr) and iron (Fe) were studied. Results: this review presents an analysis of the chemical effects of resveratrol on the oxidative stress associated with exposure to metal compounds. The interaction of resveratrol with the production of reactive oxygen species (ERO), the endogenous antioxidant system, and the effects on DNA damage are discussed. From these studies a diagram that shows the proposed interactions for resveratrol, heavy metals As, Cd, Cu, Cr and Fe, and oxidative stress is generated. Conclusions: the studies analyzed show that resveratrol is able to modulate the oxidative stress generated by different heavy metal compounds such as As, Cd, Cu, Cr and Fe.

          Resveratrol scavenges reactive oxygen species and effects radical-induced cellular responses.

          Scavenging or quenching of the reactive oxygen species (ROS) involved in oxidative stress has been the subject of many recent studies. Resveratrol, found in various natural food products, has been linked to decreased coronary artery disease and preventing cancer development. The present study measured the effect of resveratrol on several different systems involving the hydroxyl, superoxide, metal/enzymatic-induced, and cellular generated radicals. The rate constant for reaction of resveratrol with the hydroxyl radical was determined, and resveratrol was found to be an effective scavenger of hydroxyl, superoxide, and metal-induced radicals as well as showing antioxidant abilities in cells producing ROS. Resveratrol exhibits a protective effect against lipid peroxidation in cell membranes and DNA damage caused by ROS. Resveratrol was also found to have a significant inhibitory effect on the NF-kappaB signaling pathway after cellular exposure to metal-induced radicals. It was concluded that resveratrol in foods plays an important antioxidant role.

            Neuroprotective action of resveratrol.

            Low-to-moderate red wine consumption appeared to reduce age-related neurological disorders including macular degeneration, stroke, and cognitive deficits with or without dementia. Resveratrol has been considered as one of the key ingredients responsible for the preventive action of red wine since the stilbene displays a neuroprotective action in various models of toxicity. Besides its well documented free radical scavenging and anti-inflammatory properties, resveratrol has been shown to increase the clearance of beta-amyloid, a key feature of Alzheimer's disease, and to modulate intracellular effectors associated with oxidative stress (e.g. heme oxygenase), neuronal energy homeostasis (e.g. AMP kinase), program cell death (i.e. AIF) and longevity (i.e. sirtuins). This article summarizes the most recent findings on mechanisms of action involved in the protective effects of this multi target polyphenol, and discusses its possible roles in the prevention of various age-related neurological disorders. This article is part of a Special Issue entitled: Resveratrol: Challenges in translating pre-clinical findings to improved patient outcomes.

              Protective effect of curcumin against heavy metals-induced liver damage.

              Occupational or environmental exposures to heavy metals produce several adverse health effects. The common mechanism determining their toxicity and carcinogenicity is the generation of oxidative stress that leads to hepatic damage. In addition, oxidative stress induced by metal exposure leads to the activation of the nuclear factor (erythroid-derived 2)-like 2/Kelch-like ECH-associated protein 1/antioxidant response elements (Nrf2/Keap1/ARE) pathway. Since antioxidant and chelating agents are generally used for the treatment of heavy metals poisoning, this review is focused on the protective role of curcumin against liver injury induced by heavy metals. Curcumin has shown, in clinical and preclinical studies, numerous biological activities including therapeutic efficacy against various human diseases and anti-hepatotoxic effects against environmental or occupational toxins. Curcumin reduces the hepatotoxicity induced by arsenic, cadmium, chromium, copper, lead and mercury, prevents histological injury, lipid peroxidation and glutathione (GSH) depletion, maintains the liver antioxidant enzyme status and protects against mitochondrial dysfunction. The preventive effect of curcumin on the noxious effects induced by heavy metals has been attributed to its scavenging and chelating properties, and/or to the ability to induce the Nrf2/Keap1/ARE pathway. However, additional research is needed in order to propose curcumin as a potential protective agent against liver damage induced by heavy metals.
