Taurine protects the antioxidant defense system in the erythrocytes of cadmium treated mice

The present study was undertaken to investigate the protective role of taurine (2-aminoethanesulfonic acid) against cadmium (Cd) induced oxidative stress in murine erythrocytes. Cadmium chloride (CdCl₂) was chosen as the source of Cd. Experimental animals were treated with either CdCl₂ alone or taur...

Description
Summary:The present study was undertaken to investigate the protective role of taurine (2-aminoethanesulfonic acid) against cadmium (Cd) induced oxidative stress in murine erythrocytes. Cadmium chloride (CdCl₂) was chosen as the source of Cd. Experimental animals were treated with either CdCl₂ alone or taurine, followed by Cd exposure. Cd intoxication reduced hemoglobin content and the intracellular Ferric Reducing/Antioxidant Power of erythrocytes, along with the activities of antioxidant enzymes, glutathione content, and total thiols. Conversely, intracellular Cd content, lipid peroxidation, protein carbonylation, and glutathione disulphides were significantly enhanced in these cells. Treatment with taurine before Cd intoxication prevented the toxin-induced oxidative impairments in the erythrocytes of the experimental animals. Overall, the results suggest that Cd could cause oxidative damage in murine erythrocytes and that taurine may play a protective role in reducing the toxic effects of this particular metal.
