Oxidative Stress: Molecular Mechanisms, Diseases, and Therapeutic Targets

Although the physiological level of reactive oxygen species (ROS) is crucial for governing life processes through redox signaling, the excessive accumulation of ROS can contribute to biomolecular damage and pathological state, namely, oxidative stress. This review systematically summarizes the molecular mechanisms underlying the dynamic equilibrium of cellular redox state, including the intracellular sources of ROS and the multilayered antioxidant defense network. When ROS production exceeds the regulatory limits of the antioxidant system, excessive ROS will act on a series of molecular targets and participate in the pathogenesis of diseases. Therapeutic targeting of the redox balance is regarded as an…
