WebFerroptosis is a regulated form of cell death characterized by iron dependency and increased lipid peroxidation. Initially assumed to be selectively induced in tumour cells, … The production and oxidation process of GSH has multiple links that can be regulated (Fig. 3). RSL3 was discovered together with RSL5, though they function differently. RSL3 targets enzymes with nucleophilic active sites, acting on GPX4 to induce ferroptosis [37]. Other compounds, such as ML162, DPI7 and … See more Erastin, as mentioned above, was first discovered in 2003 as a genotype-selective antitumor agent. Erastin induces ferroptosis in multiple … See more NDP4928 is a small molecule that is more of an enhancer of ferroptosis than an inducer. It has been reported that NDP4928 shows … See more Ferroptosis can alternatively be induced by affecting lipid metabolism and directly producing lipid ROS (Fig. 2). In the context of the treatment of hepatocellular carcinoma, sorafenib, an FDA-certified antitumor drug, can … See more Although most ferroptosis inducers work through the three ways mentioned above, there are some inducers affecting other targets (Fig. 4). As an example, DHODH can be inhibited by brequinar. Therefore, brequinar can inhibit … See more

Prevotella histicola suppresses ferroptosis to mitigate ethanol …

WebMechanistically, autoantibodies and interferon-α present in the serum induce neutrophil ferroptosis through enhanced binding of the transcriptional repressor CREMα to the glutathione peroxidase 4 (Gpx4, the key ferroptosis regulator) promoter, which leads to suppressed expression of Gpx4 and subsequent elevation of lipid-reactive oxygen species. WebThe lethal lipid accumulation caused by glutathione depletion or inactivation of glutathione peroxidase 4 (GPX4) is characteristic of the ferroptosis process. In recent years, with the in-depth study of ferroptosis, various types of diseases have been reported to … flashcard hero windows

WebMar 4, 2024 · What is ferroptosis? Ferroptosis is a regulated mode of cell demise driven by iron-dependent peroxidation of membrane lipids [1–3,9].Such cell death can be induced upon failure of the lipid peroxide reducing system that involves glutathione peroxidase 4 (GPX4) [10,11], which enzymatically converts phospholipid hydroperoxides to nontoxic … WebFeb 2, 2024 · Ferroptosis-inducing agents (FINs) have been classified into class I FINs that involve cellular GSH depletion, and class II FINs which trigger ferroptosis through … flashcard heure
