Abstract: DJ-1, also known as Parkinson disease protein 7 (PARK7), belongs to the ThiJ/PfpI/DJ-1 superfamily of PARK7. DJ-1 is an antioxidant and antioxidant stress is its main function. In recent years, it is speculated that DJ-1 is involved in the development of preeclampsia through oxidative stress pathway. Preeclampsia (PE) is a special disease of pregnancy and a leading cause of both maternal and neonatal morbidity and mortality. However the pathophysiological mechanisms of PE remain poorly known, and the role of oxidative stress injury in the development of preeclampsia is a hot topic. The view summarized the mechanism of DJ-1 in preeclampsia.

Key words: Pre-eclampsia, Oxidative stress, Reactive oxygen species, DJ-1
