Reactive Oxygen Species 126-129 thioredoxin Homo sapiens 46-50 28688762-6 2017 Our data demonstrated that Trx decreased NADPH oxidase activity, ROS production and ICAM-1 expression in ox-LDL treated HUVECs. Reactive Oxygen Species 65-68 thioredoxin Homo sapiens 27-30 28688762-9 2017 Transient transfection of Nox4 and p22phox significantly increased intracellular ROS generation, which could be blocked by Trx overexpression. Reactive Oxygen Species 81-84 NADPH oxidase 4 Homo sapiens 26-30 28688762-9 2017 Transient transfection of Nox4 and p22phox significantly increased intracellular ROS generation, which could be blocked by Trx overexpression. Reactive Oxygen Species 81-84 cytochrome b-245 alpha chain Homo sapiens 35-42 28688762-9 2017 Transient transfection of Nox4 and p22phox significantly increased intracellular ROS generation, which could be blocked by Trx overexpression. Reactive Oxygen Species 81-84 thioredoxin Homo sapiens 123-126 28688762-11 2017 These results suggest that Trx suppresses NADPH oxidase activity in vascular endothelia under pathological conditions and may prevent the initiation of atherosclerosis by attenuating exceeding ROS production. Reactive Oxygen Species 193-196 thioredoxin Homo sapiens 27-30
