The author describes Nox3's discovery, structural components, activating factors, and broad expression across various tissues beyond the inner ear, such as in the brain, pancreas, and immune cells. A key limitation noted is that many studies show correlative changes in Nox3 mRNA expression, with few providing direct genetic or enzymatic confirmation of Nox3-derived ROS as the causal factor. The review concludes that Nox3 is a significant, yet understudied, isoform with implications for multiple physiological and pathological processes, calling for more focused research.
