WebJul 1, 2024 · Thus, GPx4, GSH, and α-tocopherol are integrated in a concerted anti-peroxidant mechanism. Recent Advances: Ferroptosis has been recently identified as a cell death subroutine that is specifically activated by missing GPx4 activity and inhibited by iron chelation or α-tocopherol supplementation. WebSep 1, 2024 · In the present study, we examined the contribution of mitochondrial GSH to ferroptotic cell death. First, we confirmed the specificity of ferroptotic cell death in H9c2 cardioblastic cells when RSL3-induced cell death was prevented by Fer-1. Second, we revealed an early response of cardiac mitochondria to ferroptosis that were found mostly ...
WebJun 2, 2012 · Abstract. Significance: Glutathione (GSH) depletion is a central signaling event that regulates the activation of cell death pathways. GSH depletion is often taken as a marker of oxidative stress ... WebMay 7, 2024 · Moreover, GSH has also been involved in other types of cell death such as necroptosis and for more details, refer to Lv's review . In line with this, one other mechanism recently described to be involved in the resistance to GSH depletion is the overexpression of deubiquitinases that inhibit protein degradation following ER-stress ( 74 ).
WebGSH is a well-known antioxidant tripeptide that also functions as a cofactor for the GPX4 enzyme. System xc − inhibition depletes cellular cysteine, making it unavailable for GSH synthesis and inactivation of GPX4. These results in the accumulation of lipid-peroxide and ROS subsequently ferroptosis cell death [20, 21]. Despite its critical ... WebMetabolomic profiling revealed GSH depletion as one mechanism of ferroptosis. •. Chemoproteomics identified GPX4 as a target for RSL3, a second ferroptosis inducer. •. …
WebGSH also modulates cell death. Apoptosis, characterized by chromatin condensation, fragmentation and internucleosomal DNA cleavage, and necrosis, characterized by rupture or fragmentation of the plasma membrane and ATP depletion can coexist and share common pathways, such as involvement of the mitochondria . GSH modulates both …
