The Effect of Resveratrol against Acrolein Toxicity in Mitochondria isolated from Rat Liver
Authors
Abstract:
Introduction: Acrolein is an important environmental, food and water pollutant that plays an important role in the development of several diseases. Resveratrol is a phenolic compound with antioxidant properties found in fruits such as grapes, berries and peanuts. The purpose of this study was to evaluate the protective effect of resveratrol in preventing Acrolein-induced toxicity in isolated mitochondria from the rat liver. Methods: Rat liver mitochondria were isolated by differential centrifugation. Different concentrations of Acrolein (100 μM to 2000 μM) were used to obtain an IC50. Different concentrations of resveratrol (2.5 μM to 40 μM) were then applied on mitochondria in the presence of Acrolein toxicity. Results: Acrolein IC50 was obtained via MTT assay as 400 μM. No toxic effect was observed for resveratrol and in the presence of Acrolein, there was a significant reduction in mitochondrial survival even at high concentrations of resveratrol compared to the control group (P < 0.001). Conclusions: The results of these study showed that resveratrol failed to exhibit a protective effect against acute Acrolein toxicity and just because a protective substance could be a marvelous antioxidant does not mean that it can prevent the mitochondrial damage resulted from any toxicant.

Doxorubicin (DOX) is an anthracycline antibiotic that has been used for a long time in therapy of an array of human malignancies either alone or in combination with other cytotoxic agents. The dose-dependent cardiotoxicity of DOX significantly limits its anticancer efficacies. Oxidative stress caused by enhanced production of reactive oxygen species is an important contributor to DOX mito...

Background and Objectives: Contact with acrolein rapidly reduces intracellular glutathione and its antioxidant capacity and causes mitochondrial dysfunction. The use of some polymeric nanocurcumin increases the stability of curcumin. In this study, the effect of these two, was investigated on acrolein-induced toxicity in mitochondria isolated from rat liver cells. Methods: In this experiment...

Pioglitazone (PG) is one of thiazolidinediones used for the treatment of type II diabetes mellitus. Some reports of its hepatotoxicity exist, but the mechanism of its hepatotoxicity is not well known. In the present study, the protective effect of some ATP suppliers are investigated against mitochondrial toxicity of PG in isolated rat mitochondria. Mitochondrial viability was investigated by MT...
