Oxygen 11-17 NADPH oxidase 4 Homo sapiens 0-4 16019190-5 2006 In the present study, we propose that the NADPH oxidase NOX4 functions as an oxygen-sensing partner and that it modulates the oxygen sensitivity of TASK-1. Oxygen 77-83 NADPH oxidase 4 Homo sapiens 56-60 16019190-5 2006 In the present study, we propose that the NADPH oxidase NOX4 functions as an oxygen-sensing partner and that it modulates the oxygen sensitivity of TASK-1. Oxygen 126-132 NADPH oxidase 4 Homo sapiens 56-60 16019190-7 2006 In HEK293 cells expressing NOX4 endogenously, the activity of expressed TASK-1 was moderately inhibited by hypoxia, and this oxygen response was significantly augmented by NOX4. Oxygen 125-131 NADPH oxidase 4 Homo sapiens 27-31 16019190-7 2006 In HEK293 cells expressing NOX4 endogenously, the activity of expressed TASK-1 was moderately inhibited by hypoxia, and this oxygen response was significantly augmented by NOX4. Oxygen 125-131 NADPH oxidase 4 Homo sapiens 172-176 16019190-8 2006 Moreover, the oxygen sensitivity of TASK-1 was abolished by NOX4 siRNA and NADPH oxidase inhibitors. Oxygen 14-20 NADPH oxidase 4 Homo sapiens 60-64 16019190-9 2006 These results suggest a novel function for NOX4 in the oxygen-dependent regulation of TASK-1 activity.
