Abstract

Schreck C, O'Connor PM. NAD(P)H oxidase and renal epithelial ion transport. Am J Physiol Regul Integr Comp Physiol 300: R1023-R1029, 2011. First published January 26, 2011; doi:10.1152/ajpregu.00618.2010.-A fundamental requirement for cellular vitality is the maintenance of plasma ion concentration within strict ranges. It is the function of the kidney to match urinary excretion of ions with daily ion intake and nonrenal losses to maintain a stable ionic milieu. NADPH oxidase is a source of reactive oxygen species (ROS) within many cell types, including the transporting renal epithelia. The focus of this review is to describe the role of NADPH oxidase-derived ROS toward local renal tubular ion transport in each nephron segment and to discuss how NADPH oxidase-derived ROS signaling within the nephron may mediate ion homeostasis. In each case, we will attempt to identify the various subunits of NADPH oxidase and reactive oxygen species involved and the ion transporters, which these affect. We will first review the role of NADPH oxidase on renal Na+ and K+ transport. Finally, we will review the relationship between tubular H+ efflux and NADPH oxidase activity.
