title: Expression of recombinant human glutathione reductase in eukaryotic cells after DNA-mediated gene transfer.
abstract: Glutathione reductase (EC 1.6.4.2) protects tissues from oxidant stress by catalyzing the NADPH-mediated reduction of glutathione disulfide to glutathione. We describe construction of a vector for DNA-mediated gene transfer and successful transient overexpression of human glutathione reductase cDNA in CHO cells. No expression was observed when the same vector was transiently transfected into NIH3T3 or LA4 cells or stably integrated in CHO cells. These results demonstrate the ability to constitute recombinant glutathione reductase expression in eukaryotic cells but suggest that this expression may be toxic.
