Mitochondrial distribution and motility are recognized as central to many cellular functions but their regulation by signaling mechanisms remains to be elucidated. Here we report that ROS, either derived from an extracellular source or intracellularly generated, controls mitochondrial distribution and function, by dose-dependently, specifically and reversibly decreasing mitochondrial motility in both rat hippocampal primary cultured neurons and cell lines. ROS decrease motility independently of cytoplasmic [Ca2+], mitochondrial membrane potential or permeability transition pore opening, known effectors of oxidative stress. However, multiple lines of genetic and pharmacological evidence support that a ROS-activated MAP kinase, p38α is required for the motility inhibition. Furthermore, anchoring mitochondria directly to kinesins without involvement of the physiological adaptors between the organelles and the motor protein prevents the H2O2–induced decrease in mitochondrial motility. Thus, ROS engage p38α and the motor adaptor complex to exert changes in mitochondrial motility, which likely has both physiological and pathophysiological relevance.
