NADPH-Oxidasen und HIF: zentrale Elemente der Redoxhomöostase

Abstract

Reactive oxygen species (ROS) are not only toxic agents but also potent signaling molecules. NADPH oxidases are the sole enzymes to generate ROS playing an important role in redox signaling. They closely interact in several ways with hypoxia-inducible transcription factors of the HIF family. This signaling network is active under normoxic and hypoxic conditions as an important regulator of redox homeostasis. Members of the NADPH oxidases-HIF axis appear as interesting therapeutic targets for various disorders characterized by an impaired redox homeostasis.
