WebJan 4, 2024 · Our animal study demonstrated that high-iron diets or the conditional knockout of Gpx4in the pancreas (genotype: Pdx1-Cre;Gpx4−/-) promoted experimental pancreatitis in mice induced by the administration of cerulein or L-arginine (a conditionally essential amino acid).4In contrast, liproxstatin-1 (a ferroptosis inhibitor) reversed this … WebJan 31, 2024 · GPX4 uses GSH as an essential cofactor to prevent lipid peroxide and maintain redox homeostasis ( 22 ). In 2008, Seiler et al. identified lipid peroxidation as the key mediator of cell death in glutathione peroxidase 4 (GPX4) knockout cells ( 23 ). Thus, people began to consider this type of cell death different from either apoptosis or necrosis.
WebAlthough heat shock protein family B (small) member 1 (HSPB1, a member of small HSP) or HSP90 also inhibits or promotes ferroptotic cancer cell death by targeting iron uptaking … WebOct 3, 2016 · GPX4 is a glutathione peroxidase that catalyzes the reduction of lipid peroxides on the cellular membrane. Lipid peroxidation and ferroptosis were observed in mouse xenografts harboring a Gpx4 knockout, highlighting the central regulating role of GPX4 in the ferroptotic pathway . However, we did not observe a change in the level of …
WebUsing genetic screens, we compared metabolic genes essential for proliferation upon inhibition of cystine uptake or glutathione peroxidase-4 (GPX4). Interestingly, very few genes were commonly required under both conditions, suggesting that cystine limitation and GPX4 inhibition may impair proliferation via distinct mechanisms.
WebNov 6, 2024 · However, as mentioned previously, SLC7A11 inhibitor HG106 can induce non-ferroptotic cell death in lung cancer cells, while GPX4 inhibitors appear to induce cancer cell-specific ferroptosis.
