Sulfhydryl Compounds 67-72 myeloperoxidase Homo sapiens 94-109 21884783-2 2011 We hypothesized that smokers would have a high level of thiocyanate (SCN(-)), a preferred substrate for MPO, which in turn would predispose to thiol oxidation, an established independent risk factor for atherosclerosis. Sulfhydryl Compounds 143-148 myeloperoxidase Homo sapiens 104-107 21884783-3 2011 In this study it is shown that on exposure to MPO/H(2)O(2), thiols on plasma proteins from nonsmokers were increasingly oxidized with increasing added SCN(-) concentrations. Sulfhydryl Compounds 60-66 myeloperoxidase Homo sapiens 46-49 21884783-5 2011 When plasma from smokers and nonsmokers was exposed to MPO/H(2)O(2)-stimulated oxidation, a strong positive correlation (r=0.8139, P<0.0001) between the extent of thiol oxidation and the plasma SCN(-) concentrations was observed. Sulfhydryl Compounds 166-171 myeloperoxidase Homo sapiens 55-58 21884783-7 2011 These data indicate that plasma SCN(-) levels are a key determinant of the extent of thiol oxidation on plasma proteins induced by MPO, and implicate HOSCN as an important mediator of inflammation-induced oxidative damage to proteins in smokers. Sulfhydryl Compounds 85-90 myeloperoxidase Homo sapiens 131-134
