DNA Repair Genes in Parkinson's Disease

Abstract

In conclusion, our findings have suggested that APE1, XRCC1, and XRCC3 genetic variants may be a risk factor by increasing oxidative stress that might cause the loss of dopaminergic cells in the substantiata nigra and locus caeruleus, leading to abnormal signal transmittion, and ultimately, the development of PD. In addition, generation of reactive oxygen species from dopamine might affect the other DNA repair pathway proteins that we did not examine in the current study. Further studies with larger sample groups are necessary to clarify the role of DNA repair genes and the development of PD.
