Interplay between vitamin E, 5-lipoxygenase, mitochondrial damage, and apoptosis of mononuclear cells. ESRD patients on maintenance HD show enhanced 5-lipoxygenase (5-LOX) activity in peripheral blood mononuclear cells, which leads to increased membrane lipoperoxides and cytosolic reactive oxygen species (ROS), and to reduced mitochondrial membrane potential (ΔΨ). The increased cytochrome c (cyt c) release from mitochondria activates the caspase cascade, which, together with lipoperoxide and ROS formation, triggers nuclear alterations and ultimately leads to apoptosis. Oral or intramuscular (IM) administration of vitamin E, as well as the filter-bound form, increases the plasma level of vitamin E, which prevents ESRD/HD-induced apoptosis by directly inhibiting 5-LOX activity.
