Model of the intracellular signaling mechanisms underlying OA-Alb induced superoxide production in renal proximal tubular cells. Proteinuria associated with physiologic luminal acidification cooperatively induces robust Pyk2 activation in proximal tubular cells. The activated Pyk2 induces extensive ROS accumulation through activation of c-Src and NAD(P)H oxidase.
