Замечательный последовательный обзор роли окислительно -
восстановительного потенциала в регуляции функции митохондрий и
клетки вообще, значения свободных радикалов во внутреклеточном
сигнализировании. Детально освещено функционирование естественных
антиоксидантных механизмов.
Redox-dependent processes influence most cellular functions, such
as differentiation, proliferation, and apoptosis. Mitochondria are
at the center of these processes, as mitochondria both generate
reactive oxygen species (ROS) that drive redox-sensitive events and
respond to ROS-mediated changes in the cellular redox state. In
this review, we examine the regulation of cellular ROS, their modes
of production and removal, and the redoxsensitive targets that are
modified by their flux. In particular, we focus on the actions of
redox-sensitive targets that alter mitochondrial function and the
role of these redox modifications on metabolism, mitochondrial
biogenesis, receptor-mediated signaling, and apoptotic pathways. We
also consider the role of mitochondria in modulating these
pathways, and discuss how redox-dependent events may contribute to
pathobiology by altering mitochondrial function.
