The purpose of this study is to characterize oxidative stress and the Nrf2 antioxidant response in early stages of Autosomal Dominant Polycystic Kidney Disease (ADPKD), while identifying candidate biomarkers.
Intracellular Reactive Oxygen Species (ROS) concentration is a major determinant of cellular fate and is finely regulated by the cell's antioxidant systems. While low levels of ROS are required for pro-survival signaling, cell proliferation, growth, and energy metabolism, the excess of ROS or oxidative stress leads to inflammation, cell death, and disease/injury progression. Indeed, oxidative stress is commonly observed in several renal diseases including ADPKD. On the other hand, a surplus of antioxidants will not only neutralize ROS, but may result in the antithesis of oxidative stress, whic…
