Abstract
CuZn superoxide dismutase (SOD) secretion was detected in media of [ 35S]cysteine-labeled human neuroblastoma SK-N-BE cells precipitated with antihuman CuZn SOD antibodies. The ability of Fe 2+/ascorbate oxidative stress to induce CuZn SOD in SK-N-BE cells was evaluated by Western blot analysis. The results showed that, like human hepatocarcinoma cells and human fibroblasts, SK-N-BE cells secrete CuZn SOD. In addition, the CuZn SOD concentration was higher in cells subjected to oxidative stress than in unstressed cells. The secretion of CuZn SOD and the ability of Fe 2+/ascorbate to increase its protein content in SK-N-BE cells indicates that this enzyme protects the brain from damage induced by oxidative stress.
