We measured the amounts of six antioxidant enzymes-SOD1, catalase, glutathione peroxidase 1 (GPx1), as well as peroxiredoxins (Prxs) I, II, and VI-in red blood cells (RBCs) of SCD patients and control subjects. The amounts of SOD1 and Prx VI were reduced by about 17% and 20%, respectively, in SCD RBCs compared with control cells. The amounts of Prx II and GPx1 did not differ between SCD and normal RBCs. However, about 18% of Prx II was inactivated in SCD RBCs as a result of oxidation to sulfinic Prx II, whereas inactive Prx II was virtually undetectable in control cells. Furthermore, GPx1 activity was reduced by about 33% in SCD RBCs, and the loss of activity was correlated with hemolysis in SCD patients. RBCs from SCD patients taking hydroxyurea demonstrated 90% higher GPx1 activity than did those from untreated SCD patients, with no differences seen for the other catalytic antioxidants. Hydroxyurea induced GPx1 expression in multiple cultured cell lines in a manner dependent on both p53 and NO-cGMP signaling pathways. GPx1 expression represents a previously unrecognized potential benefit of hydroxyurea treatment in SCD patients."xsd:string |
