Lipid peroxidation in cell death.
Disruption of redox homeostasis is a key phenotype of many pathological conditions. Though multiple oxidizing compounds such as hydrogen peroxide are widely recognized as mediators and inducers of oxidative stress, increasingly, attention is focused on the role of lipid hydroperoxides as critical mediators of death and disease. As the main component of cellular membranes, lipids have an indispe...
متن کاملFerroptosis: Death by Lipid Peroxidation.
Ferroptosis is a regulated form of cell death driven by loss of activity of the lipid repair enzyme glutathione peroxidase 4 (GPX4) and subsequent accumulation of lipid-based reactive oxygen species (ROS), particularly lipid hydroperoxides. This form of iron-dependent cell death is genetically, biochemically, and morphologically distinct from other cell death modalities, including apoptosis, un...
متن کاملLipid peroxidation is essential for α-synuclein-induced cell death
Parkinson's disease is the second most common neurodegenerative disease and its pathogenesis is closely associated with oxidative stress. Deposition of aggregated α-synuclein (α-Syn) occurs in familial and sporadic forms of Parkinson's disease. Here, we studied the effect of oligomeric α-Syn on one of the major markers of oxidative stress, lipid peroxidation, in primary co-cultures of neurons a...
متن کاملLipid peroxidation in cell membrane phospholipids
duced by reactive oxygen species and/or free radicals leads to alterations in the membrane structure and functions of cells, and has been proposed as a major mechanism for the onset of several pathological events in vivo, including postischemicreperfusion injury, cancer, senile dementia and aging. A number of studies have shown that peroxidation of membrane lipids in cells gives rise to highly ...
متن کاملPeroxide-induced cell death and lipid peroxidation in C6 glioma cells.
Peroxides are often used as models to induce oxidative damage in cells in vitro. The aim of the present study was to elucidate the role of lipid peroxidation in peroxide-induced cell death. To this end (i) the ability to induce lipid peroxidation in C6 rat astroglioma cells of hydrogen peroxide (H2O2), cumene hydroperoxide (CHP) and t-butyl hydroperoxide (t-BuOOH) (ii) the relation between pero...
