Hydrogen Peroxide 25-29 Rac family small GTPase 1 Rattus norvegicus 273-277 16354758-8 2006 Decreased Rac1 activity lowers intracellular H(2)O(2) levels, thus attenuating cell motility. Hydrogen Peroxide 45-53 Rac family small GTPase 1 Rattus norvegicus 10-14 35390465-4 2022 Here, we show that treatment with 6-OHDA, MPP+ or rotenone induced H2O2 generation by upregulating the levels of NOX2 and its regulatory proteins (p22phox, p40phox, p47phox, p67phox, and Rac1), leading to apoptotic cell death in PC12 cells and primary neurons. Hydrogen Peroxide 67-71 Rac family small GTPase 1 Rattus norvegicus 187-191 15475011-0 2004 Hydrogen peroxide mediates Rac1 activation of S6K1. Hydrogen Peroxide 0-17 Rac family small GTPase 1 Rattus norvegicus 27-31 15475011-6 2004 In contrast, Rat2 cells stably transfected with Rac1V12 produced high level of H2O2 in the absence of PDGF, comparable to that in the control cells stimulated with PDGF. Hydrogen Peroxide 79-83 Rac family small GTPase 1 Rattus norvegicus 48-55 15475011-7 2004 More importantly, elimination of H2O2 produced in Rat2 cells overexpressing Rac1V12 inhibited the Rac1V12 activation of S6K1, indicating the possible role of H2O2 as a mediator in the activation of S6K1 by Rac1. Hydrogen Peroxide 33-37 Rac family small GTPase 1 Rattus norvegicus 76-83 15475011-7 2004 More importantly, elimination of H2O2 produced in Rat2 cells overexpressing Rac1V12 inhibited the Rac1V12 activation of S6K1, indicating the possible role of H2O2 as a mediator in the activation of S6K1 by Rac1. Hydrogen Peroxide 33-37 Rac family small GTPase 1 Rattus norvegicus 98-105 15475011-7 2004 More importantly, elimination of H2O2 produced in Rat2 cells overexpressing Rac1V12 inhibited the Rac1V12 activation of S6K1, indicating the possible role of H2O2 as a mediator in the activation of S6K1 by Rac1. Hydrogen Peroxide 33-37 Rac family small GTPase 1 Rattus norvegicus 76-80 15475011-7 2004 More importantly, elimination of H2O2 produced in Rat2 cells overexpressing Rac1V12 inhibited the Rac1V12 activation of S6K1, indicating the possible role of H2O2 as a mediator in the activation of S6K1 by Rac1. Hydrogen Peroxide 158-162 Rac family small GTPase 1 Rattus norvegicus 76-83 15475011-7 2004 More importantly, elimination of H2O2 produced in Rat2 cells overexpressing Rac1V12 inhibited the Rac1V12 activation of S6K1, indicating the possible role of H2O2 as a mediator in the activation of S6K1 by Rac1. Hydrogen Peroxide 158-162 Rac family small GTPase 1 Rattus norvegicus 98-105 15475011-7 2004 More importantly, elimination of H2O2 produced in Rat2 cells overexpressing Rac1V12 inhibited the Rac1V12 activation of S6K1, indicating the possible role of H2O2 as a mediator in the activation of S6K1 by Rac1. Hydrogen Peroxide 158-162 Rac family small GTPase 1 Rattus norvegicus 76-80 15475011-9 2004 Taken together, these results suggest that H2O2 plays a pivotal role as a mediator in Rac1 activation of S6K1. Hydrogen Peroxide 43-47 Rac family small GTPase 1 Rattus norvegicus 86-90 15475011-2 2004 In this study, we investigated a possible role of H2O2 as a molecular linker in Rac1 activation of S6K1. Hydrogen Peroxide 50-54 Rac family small GTPase 1 Rattus norvegicus 80-84 15213258-8 2004 It was also shown that SMV, by inhibiting Rac1 activity, reversed Ang II-induced increase in intracellular H2O2 production, Akt activation, and p27 protein expression.
