Abstract: | AbstractAcrylamide is a highly soluble and widely produced industrial chemical that has been shown to pose numerous health hazards. This study aimed to assess the effects of acrylamide on the cytotoxicity and oxidative damage in embryonic fibroblast cells (BALB/c 3T3) and to measure protective roles of the natural antioxidants vitamin C and curcumin. Embryonic fibroblast cells were exposed to acrylamide at concentrations of 1, 10, 100, and 1000?μmol/L and vitamin C (50?μmol/L) or curcumin (2.5?μmol/L) for 24?h. Cell viability, cytotoxicity, the activities of antioxidant enzymes superoxide dismutase, glutathione-S-transferase, glutathione peroxidase and catalase, and the markers of oxidative lipid peroxidation, hydroxyl radical, hydrogen peroxide and glutathione were measured. Co-treatment of the acrylamide-exposed fibroblast cells with vitamin C or curcumin attenuated the cytotoxicity and formation of reactive oxygen species and decreased the antioxidant enzyme activity. Thus, it was concluded that vitamin C and curcumin may play a protective role against acrylamide toxicity; the treatment with 50?μmol/L vitamin C was found to be more effective than the treatment with 2.5?μmol/L curcumin. |
