The molecular machinery of regulated cell death

Cell Research, Journal Year: 2019, Volume and Issue: 29(5), P. 347 - 364

Published: April 4, 2019

Cells may die from accidental cell death (ACD) or regulated (RCD). ACD is a biologically uncontrolled process, whereas RCD involves tightly structured signaling cascades and molecularly defined effector mechanisms. A growing number of novel non-apoptotic forms have been identified are increasingly being implicated in various human pathologies. Here, we critically review the current state art regarding types RCD, including necroptosis, pyroptosis, ferroptosis, entotic death, netotic parthanatos, lysosome-dependent autophagy-dependent alkaliptosis oxeiptosis. The in-depth comprehension each these lethal subroutines their intercellular consequences uncover therapeutic targets for avoidance pathogenic loss.

Ferroptosis as a target for protection against cardiomyopathy

Proceedings of the National Academy of Sciences, Journal Year: 2019, Volume and Issue: 116(7), P. 2672 - 2680

Published: Jan. 28, 2019

Significance Nonapoptotic cell death-induced tissue damage has been implicated in a variety of diseases, including neurodegenerative disorder, inflammation, and stroke. In this study, we demonstrate that ferroptosis, newly defined iron-dependent death, mediates both chemotherapy- ischemia/reperfusion-induced cardiomyopathy. RNA-sequencing analysis revealed up-regulation heme oxygenase 1 by doxorubicin as major mechanism ferroptotic As result, degrades releases free iron cardiomyocytes, which turn leads to generation oxidized lipids the mitochondria membrane. Most importantly, chelation therapy pharmacologically blocking ferroptosis could significantly alleviate cardiomyopathy mice. These findings suggest targeting strategy for treating deadly heart disease.

Reactive Oxygen Species-Induced Lipid Peroxidation in Apoptosis, Autophagy, and Ferroptosis

Oxidative Medicine and Cellular Longevity, Journal Year: 2019, Volume and Issue: 2019, P. 1 - 13

Published: Oct. 13, 2019

Reactive oxygen species- (ROS-) induced lipid peroxidation plays a critical role in cell death including apoptosis, autophagy, and ferroptosis. This fundamental conserved mechanism is based on an excess of ROS which attacks biomembranes, propagates chain reactions, subsequently induces different types death. A highly evolved sophisticated antioxidant system exists that acts to protect the cells from oxidative damage. In this review, we discussed how propagate reactions products initiate apoptosis autophagy current models. We also during ferroptosis, summarized pathological conditions illness. aim bring more global integrative sight know ROS-induced occurs among

NRF2 plays a critical role in mitigating lipid peroxidation and ferroptosis

Redox Biology, Journal Year: 2019, Volume and Issue: 23, P. 101107 - 101107

Published: Jan. 12, 2019

The transcription factor nuclear erythroid 2-related 2 (NRF2) is a key regulator of the cellular antioxidant response, controlling expression genes that counteract oxidative and electrophilic stresses. Many pathological conditions are linked to imbalances in redox homeostasis, illustrating important role defense systems preventing pathogenic effects associated with accumulation reactive species. In particular, it becoming increasingly apparent lipid peroxides has an driving pathogenesis multiple disease states. A example this recent discovery novel form cell death termed ferroptosis. Ferroptosis iron-dependent, peroxidation-driven cascade become target development anti-cancer therapies, as well prevention neurodegenerative cardiovascular diseases. review, we will provide brief overview peroxidation, components involved ferroptotic cascade. We also highlight NRF2 signaling pathway mediating peroxidation ferroptosis, focusing on established mitigate these pathways, relevance NRF2-lipid peroxidation-ferroptosis axis disease.

Cystine transporter SLC7A11/xCT in cancer: ferroptosis, nutrient dependency, and cancer therapy

Protein & Cell, Journal Year: 2020, Volume and Issue: 12(8), P. 599 - 620

Published: Oct. 1, 2020

Abstract The cystine/glutamate antiporter SLC7A11 (also commonly known as xCT) functions to import cystine for glutathione biosynthesis and antioxidant defense is overexpressed in multiple human cancers. Recent studies revealed that overexpression promotes tumor growth partly through suppressing ferroptosis, a form of regulated cell death induced by excessive lipid peroxidation. However, cancer cells with high expression (SLC7A11 ) also have endure the significant cost associated SLC7A11-mediated metabolic reprogramming, leading glucose- glutamine-dependency cells, which presents potential vulnerabilities therapeutic targeting cancer. In this review, we summarize diverse regulatory mechanisms cancer, discuss ferroptosis-dependent -independent promoting development, explore mechanistic basis SLC7A11-induced nutrient dependency conceptualize strategies target treatment. This review will provide foundation further understanding dependency, biology developing novel effective therapies.

Abstract Ferroptosis is an iron-dependent cell death, which different from apoptosis, necrosis, autophagy, and other forms of death. The process ferroptotic death defined by the accumulation lethal lipid species derived peroxidation lipids, can be prevented iron chelators (e.g., deferiprone, deferoxamine) small lipophilic antioxidants ferrostatin, liproxstatin).
