NAD 8-12 angiotensinogen Homo sapiens 43-57 9740615-0 1998 Role of NADH/NADPH oxidase-derived H2O2 in angiotensin II-induced vascular hypertrophy. Hydrogen Peroxide 35-39 angiotensinogen Homo sapiens 43-57 9740615-2 1998 We previously showed that angiotensin II (Ang II) increases superoxide production by activating an NADH/NADPH oxidase, which contributes to hypertrophy. Superoxides 60-70 angiotensinogen Homo sapiens 26-40 9740615-2 1998 We previously showed that angiotensin II (Ang II) increases superoxide production by activating an NADH/NADPH oxidase, which contributes to hypertrophy. Superoxides 60-70 angiotensinogen Homo sapiens 42-48 9740615-3 1998 In this study, we determined whether Ang II stimulation of this oxidase results in H2O2 production by studying the effects of Ang II on intracellular H2O2 generation, intracellular superoxide dismutase and catalase activity, and hypertrophy. Hydrogen Peroxide 83-87 angiotensinogen Homo sapiens 37-43 9740615-4 1998 Ang II (100 nmol/L) significantly increased intracellular H2O2 levels at 4 hours. Hydrogen Peroxide 58-62 angiotensinogen Homo sapiens 0-6 9740615-5 1998 Neither superoxide dismutase activity nor catalase activity was affected by Ang II; the SOD present in VSMCs is sufficient to metabolize Ang II-stimulated superoxide to H2O2, which accumulates more rapidly than it is degraded by catalase. Hydrogen Peroxide 169-173 angiotensinogen Homo sapiens 76-82 9740615-5 1998 Neither superoxide dismutase activity nor catalase activity was affected by Ang II; the SOD present in VSMCs is sufficient to metabolize Ang II-stimulated superoxide to H2O2, which accumulates more rapidly than it is degraded by catalase. Hydrogen Peroxide 169-173 angiotensinogen Homo sapiens 137-143 9740615-5 1998 Neither superoxide dismutase activity nor catalase activity was affected by Ang II; the SOD present in VSMCs is sufficient to metabolize Ang II-stimulated superoxide to H2O2, which accumulates more rapidly than it is degraded by catalase. Hydrogen Peroxide 169-173 catalase Homo sapiens 229-237 9740615-6 1998 This increase in H2O2 was inhibited by extracellular catalase, diphenylene iodonium, an inhibitor of the NADH/NADPH oxidase, and the AT1 receptor blocker losartan. Hydrogen Peroxide 17-21 catalase Homo sapiens 53-61 9740615-7 1998 In VSMCs stably transfected with antisense p22phox, a critical component of the NADH/NADPH oxidase in which oxidase activity was markedly reduced, Ang II-induced production of H2O2 was almost completely inhibited, confirming that the source of Ang II-induced H2O2 was the NADH/NADPH oxidase. Hydrogen Peroxide 176-180 cytochrome b-245 alpha chain Homo sapiens 43-50 9740615-7 1998 In VSMCs stably transfected with antisense p22phox, a critical component of the NADH/NADPH oxidase in which oxidase activity was markedly reduced, Ang II-induced production of H2O2 was almost completely inhibited, confirming that the source of Ang II-induced H2O2 was the NADH/NADPH oxidase. Hydrogen Peroxide 176-180 angiotensinogen Homo sapiens 147-153 9740615-7 1998 In VSMCs stably transfected with antisense p22phox, a critical component of the NADH/NADPH oxidase in which oxidase activity was markedly reduced, Ang II-induced production of H2O2 was almost completely inhibited, confirming that the source of Ang II-induced H2O2 was the NADH/NADPH oxidase. Hydrogen Peroxide 259-263 cytochrome b-245 alpha chain Homo sapiens 43-50 9740615-7 1998 In VSMCs stably transfected with antisense p22phox, a critical component of the NADH/NADPH oxidase in which oxidase activity was markedly reduced, Ang II-induced production of H2O2 was almost completely inhibited, confirming that the source of Ang II-induced H2O2 was the NADH/NADPH oxidase. Hydrogen Peroxide 259-263 angiotensinogen Homo sapiens 147-153 9740615-8 1998 Using a novel cell line that stably overexpresses catalase, we showed that this increased H2O2 is a critical step in VSMC hypertrophy, a hallmark of many vascular diseases. Hydrogen Peroxide 90-94 catalase Homo sapiens 50-58 9740615-9 1998 Inhibition of intracellular superoxide dismutase by diethylthiocarbamate (1 mmol/L) also resulted in attenuation of Ang II-induced hypertrophy (62+/-2% inhibition).
