WebJul 5, 2024 · Collectively, these results indicate that superoxide production from complex III plays a pivotal role in the ferroptosis that is induced by Cys starvation, suggesting that protecting mitochondria is a promising therapeutic strategy for the treatment of multiple diseases featuring ferroptosis. WebMay 10, 2024 · When the transsulfuration pathway is activated, the sulfur atom of methionine (Met) is utilized to generate Cys, which can then suppress Cys-starvation-induced ferroptosis. In the current study, we cultured HeLa cells in Met- and/or cystine (an oxidized Cys dimer)- deprived medium and investigated the roles of Met in ferroptosis …
WebJul 27, 2024 · Our results indicate that, when mouse hepatoma Hepa 1-6 cells are incubated with NOC18, cell death induced by various ferroptotic stimuli such as cysteine (Cys) starvation, the inhibition of glutathione peroxidase 4 (GPX4) and treatment with tertiary-butyl hydroperoxide (TBHP) is significantly reduced. WebSep 1, 2010 · In this short paper, we test the hypothesis that Met and Cys starvation arising during Cr exposure is the cause of Cr-induced mRNA mistranslation. The results showed …
WebMar 30, 2024 · Since it has been reported that Cys starvation and the subsequent ferroptotic processes are associated with the hyperpolarization of MMP [11], we explored … WebVapC4 mimics a state of Cys starvation, which then activated Cys- attenuation at sORFs to globally redirect metabolism towards the synthesis of free Cys. The resulting newly enriched pool of Cys feeds into the synthesis of mycothiol, the glutathione counterpart in this pathogen that is responsible for maintaining cellular redox homeostasis ...
WebThis study indicates how cells save themselves under cystine or Cys starvation conditions, but it does not explain how Glu accumulation promotes ferroptosis. The function of glutaminolysis in ferroptosis could also be explained by the discovery that α-KG, a product of glutaminolysis, could substitute Gln to function in Cys deprivation-induced ...
WebJul 7, 2024 · Inhibiting the mitochondrial electron transport chain also attenuates ferroptosis induced by cys starvation, as does depletion of mitochondria (Gao et al., 2024; Figure 3). The role of the electron transport chain may be due to the leakage of electrons that produce superoxide and H 2 O 2 , which can then react with Fe(II) to drive Fenton ... signs and symptoms of vomitingWebFeb 1, 2024 · Furthermore, NOC18, another NO donor, could inhibit ferroptosis induced by numerous treatments including Cys starvation, GPX4 inhibition, and TBHP treatment. However, NOC18 does not alter iron status during ferroptosis, but disrupts ferroptosis by terminating the lipid peroxidation chain reaction [8].
