Oxidative Stress: Signaling Pathways, Biological Functions, and Disease.

Summary

This review, published in MedComm in 2025, provides a comprehensive synthesis of current understanding of oxidative stress, covering its molecular origins, key signalling cascades, and roles in normal cellular function and disease pathogenesis. The authors likely examine how imbalances between ROS production and antioxidant capacity contribute to conditions including cardiovascular disease, neurodegeneration, cancer, and metabolic disorders. The paper is likely intended as a reference resource for researchers working across biomedical disciplines where oxidative stress is a mechanistic focus.

UK applicability

Although this is an international biomedical review rather than a UK-specific study, its findings are broadly applicable to UK clinical and public health contexts, particularly in relation to diet-derived antioxidants, chronic disease prevention, and the nutritional quality of food as it relates to oxidative stress mitigation.

Key measures

Reactive oxygen species (ROS) levels; antioxidant enzyme activity (e.g. superoxide dismutase, catalase, glutathione peroxidase); biomarkers of oxidative damage (e.g. malondialdehyde, 8-OHdG); disease associations and signalling pathway activation

Outcomes reported

The paper likely reviews the molecular signalling pathways underpinning oxidative stress, its physiological and pathological roles, and its associations with a range of chronic and acute diseases. It probably synthesises evidence on reactive oxygen species (ROS) generation, antioxidant defence mechanisms, and downstream biological consequences.
