4 In this paper, we demonstrate that H2O2 at pathological concentrations triggers the fibrillization of wild-type SOD1 both in vitro and in SH-SY5Y cells. Hydrogen Peroxide superoxide dismutase 1 Homo sapiens
5 Using an anti-dimedone antibody that detects sulfenic acid modification of proteins, we found that Cys-111 in wild-type SOD1 is oxidized to C-SOH by pathological concentration of H2O2, followed by the formation of sulfenic acid modified SOD1 oligomers. Hydrogen Peroxide superoxide dismutase 1 Homo sapiens
6 Thus, we propose that H2O2 at pathological concentrations triggers the fibrillization of wild-type SOD1 and subsequently induces SOD1 toxicity and TDP-43 toxicity in neuronal cells via sulfenic acid modification of Cys-111 in SOD1. Hydrogen Peroxide superoxide dismutase 1 Homo sapiens
7 Thus, we propose that H2O2 at pathological concentrations triggers the fibrillization of wild-type SOD1 and subsequently induces SOD1 toxicity and TDP-43 toxicity in neuronal cells via sulfenic acid modification of Cys-111 in SOD1. Hydrogen Peroxide superoxide dismutase 1 Homo sapiens

9 These findings can explain how H2O2 at pathologic concentrations regulates the misfolding and toxicity of SOD1 and TDP-43 associated with ALS, and suggest that sulfenic acid modification of wild-type SOD1 should play pivotal roles in the pathogenesis of sporadic ALS.
