Abstract:Parkinson’s disease is characterized by the substantia nigra pars compacta dopaminergic neuron-specific death and the presence of eosinophilic inclusion bodies-Lewy bodies which’s main component is α- synuclein in residual neuronal. Recent studies show that oxidative stress is a leading cause of brain dopaminergic neuron-specific death. DJ-1 (Park7) gene is an autosomal recessive Parkinson’s disease related genes. DJ-1 protein has a strong antioxidant effect,mainly acts as identity of active oxygen scavenger,chaperones,signaling pathways regulating molecules to against the oxidative stress,thereby protecting dopamine neurons from damage. Both deletion and mutation of DJ-1 gene will cause the reduction of its anti-oxidative stress,resulting in neuronal death,and this situation may be rescued by overexpression of DJ-1 protein. Because of the important role of DJ-1 in the development and occurrence of Parkinson’s disease,the paper will expand on its review of new research,and discuss primarily from the relationship between DJ-1 and oxidative stress.

Key words:Parkinson&,rsquo,s disease(PD),DJ-1,oxidative stress,reactive oxygen species(ROS)
