Hydroxyl Radical 228-236 synuclein alpha Homo sapiens 171-180 16984000-3 2006 Hydrogen peroxide is catalytically converted to the aggressive hydroxyl radical in the presence of Fe(II) and Cu(I), which renders amyloidogenic proteins such as beta-amyloid and alpha-synuclein (implicated in Alzheimer"s disease (AD) and Parkinson"s disease (PD), respectively) vulnerable to self-inflicted hydroxyl radical attack. Hydroxyl Radical 63-79 synuclein alpha Homo sapiens 179-194 23123341-9 2013 Through the measurements of H(2)O(2) and hydroxyl radicals (OH) in solutions containing different forms of Cu (II) (free and complexed by unstructured or alpha-helical alpha-syn), we demonstrate that the significantly enhanced Cu (I) binding affinity helps inhibit the production of highly toxic reactive oxygen species, especially the hydroxyl radicals. Hydroxyl Radical 336-353 synuclein alpha Homo sapiens 168-177 16984000-3 2006 Hydrogen peroxide is catalytically converted to the aggressive hydroxyl radical in the presence of Fe(II) and Cu(I), which renders amyloidogenic proteins such as beta-amyloid and alpha-synuclein (implicated in Alzheimer"s disease (AD) and Parkinson"s disease (PD), respectively) vulnerable to self-inflicted hydroxyl radical attack. Hydroxyl Radical 308-324 synuclein alpha Homo sapiens 179-194 12661766-6 2003 These results suggest that the oligomerization of alpha-synuclein is mediated by the generation of the hydroxyl radical through the metal-catalyzed reaction. Hydroxyl Radical 103-119 synuclein alpha Homo sapiens 50-65 12031892-0 2002 Formation of hydrogen peroxide and hydroxyl radicals from A(beta) and alpha-synuclein as a possible mechanism of cell death in Alzheimer"s disease and Parkinson"s disease. Hydroxyl Radical 35-52 synuclein alpha Homo sapiens 70-85 12031892-3 2002 We have shown recently that solutions of A(beta) 1-40, A(beta) 1-42, A(beta) 25-35, alpha-synuclein and non-A(beta) component (NAC; residues 61-95 of alpha-synuclein) all liberate hydroxyl radicals upon incubation in vitro followed by the addition of small amounts of Fe(II). Hydroxyl Radical 180-197 synuclein alpha Homo sapiens 127-130 12031892-5 2002 Hydroxyl radical formation was inhibited by the inclusion of catalase or metal-chelators during A(beta) or alpha-synuclein incubation. Hydroxyl Radical 0-16 synuclein alpha Homo sapiens 107-122 12196137-9 2002 Toxicity induced by alpha-synuclein, NAC and NAC(1-18) oligomers occurs via an apoptotic mechanism, possibly initiated by oxidative damage, since these peptides liberate hydroxyl radicals in the presence of iron. Hydroxyl Radical 170-187 synuclein alpha Homo sapiens 20-35 12196137-9 2002 Toxicity induced by alpha-synuclein, NAC and NAC(1-18) oligomers occurs via an apoptotic mechanism, possibly initiated by oxidative damage, since these peptides liberate hydroxyl radicals in the presence of iron. Hydroxyl Radical 170-187 synuclein alpha Homo sapiens 37-40 12453634-5 2002 Hydroxyl radical scavengers and spin-trapping agent such as 5,5"-dimethyl 1-pyrolline N-oxide and tert-butyl-alpha-phenylnitrone significantly inhibited the aggregation of alpha-synuclein. Hydroxyl Radical 0-16 synuclein alpha Homo sapiens 172-187 12453634-7 2002 This indicates that the aggregation of alpha-synuclein can be mediated by the CP/H(2)O(2) system via the generation of hydroxyl radical. Hydroxyl Radical 119-135 synuclein alpha Homo sapiens 39-54 11958955-7 2002 These results suggest that the aggregation of alpha-synuclein is mediated by the Cu,Zn-SOD/H(2)O(2) system via the generation of hydroxyl radical by the free radical-generating function of the enzyme. Hydroxyl Radical 129-145 synuclein alpha Homo sapiens 46-61
