Abstract:
:Dopamine can be autoxidized to superoxides and quinones. Superoxides can form hydroxyl radicals that are highly reactive with lipids, proteins and DNA leading to neuronal damage and cell death. We used a clonal catecholaminergic cell line (CATH.a) derived from the central nervous system to evaluate the effects of dopamine on cell death, lipid peroxidation and DNA base damage. Dopamine produces cell death in CATH.a cells and this is associated with an increase in annexin binding, which is an early indicator of apoptosis. Incubation of CATH.a cells with deferoximine, an iron chealator, partially antagonizes dopamine-induced cell death. In CATH.a cells, dopamine produces an increase in both lipid peroxidation, as measured by cis-parinaric acid fluorescence, and DNA oxidative base damage, as measured by 8-hydroxy-2'-deoxyguanosine formation. Cell death was inhibited 84-92% by the hydrophilic antioxidants, dithiothreitol, L-cysteine, and N-acetylcysteine. The lipophilic vitamins, retinol and vitamin E and the vitamin E analog, Trolox, inhibited dopamine-induced cell death by 18-33%. The lipophilic antioxidants probucol, propyl glycol and butylated hydroxyanisone had no inhibitory effect on dopamine-induced cell death. These data suggest that damage to DNA and lipids may be partially responsible for dopamine-induced cell death in CATH.a cells.
