abstract::6-Hydroxydopamine (6-OHDA) is a neurotoxin to produce an animal model of Parkinson's disease. 6-OHDA increased the formation of 8-oxo-7, 8-dihydro-2'-deoxyguanosine (8-oxodG), a biomarker of oxidatively damaged DNA, and induced apoptosis in human neuroblastoma SH-SY5Y cells. Iron or copper chelators inhibited 6-OHDA-i...
