Oxidative stress has been implicated in the pathogenesis of preeclampsia. This study measured the relative mRNA expression of antioxidant proteins glutathione peroxidase 1 and 4, glutathione reductase, thioredoxin 1 and 2, thioredoxin reductase 1, thioredoxin peroxidase 3 and superoxide dismutase 1 and 2 in preeclamptic and non-preeclamptic placentae. Quantitative real-time PCR was conducted on placental mRNA isolated from preeclamptic and control patients. Cycle threshold numbers and fold differences were calculated as a measure of linear product amplification and used for comparison. The mRNA expression of glutathione reductase was significantly reduced (fold difference 0.41, p<0.05) in pr..
