Abstract
Both acute kidney injury (AKI) and chronic kidney disease (CKD) are major causes of renal failure in humans and are associated with high incidences of morbidity and mortality rates. AKI and CKD are closely interconnected, and fueled by the obesity and diabetes epidemic, their prevalence is alarmingly increasing to the point that it currently represents a major heath issue worldwide. The kidney is an organ that is particularly sensitive to redox imbalance, resulting in excessive production of reactive oxygen species. Oxidative stress is viewed as a critical pathogenic factor implicated in the initiation, development, and progression of most renal diseases. This Forum discusses the redox-dependent factors and mechanisms accounting for the perturbation of renal function and circulation in the context of the major kidney pathologies linked to hypertension, diabetes, and cancer.
