    Preeclampsia is a common disease of pregnancy that is characterized by symptoms such as high blood pressure and proteinuria. Peroxiredoxin 4 (Prx4), is a protein with antioxidant properties which is produced in placenta and protects it from antioxidant stress and recurrent miscarriage. For regeneration of Peroxiredoxin 4 need to glutathione (GSH) and Glutamate-cysteine ligase (GCL) enzyme controls the pathway of glutathione regeneration. Apelin is a paired internal ligand with a G protein coupled receptor and is associated with angiotensin receptor (AT1) as a blood pressure regulator. This study was designed to evaluate GCL enzyme activity and Peroxiredoxin 4, glutathione and apelin levels in serum of women with preeclampsia. Thirty pregnant women with preeclampsia and 30 healthy pregnant women were enrolled in this study. All participants were diagnosed by clinical examination and confirmation by Obstetrician-Gynecologist. The GCL enzyme activity and concentration of Prx4 and apelin in serum samples were measured using ready-to-use non-competitive ELISA methods while glutathione level was determined using Ellman's reagent. The GCL enzyme activity and Prx4 level were significantly lower in preeclampsia compared with control group (p < 0.05). In addition, marked reductions were observed in the concentrations of glutathione and apelin in preeclampsia compared to the healthy pregnant women (p < 0.05). This study identified the role of the GCL and Prx4 system in preeclampsia disorder and may be one of the ways to prevent and reduce the risks of preeclampsia in high-risk women using diet control and stress reduction.
