Furthermore, we analyzed various oxidative and antioxidant markers, including malondialdehyde (MDA), SOD, glutathione peroxidase (Gpx), total antioxidant capacity (TAC), as well as trace elements such as zinc (Zn), selenium (Se), and copper (Cu), to evaluate the redox balance in patients with preeclampsia. The gene discussed is SOD1; the disease is preeclampsia.
