Cys starvation
WebDec 1, 2024 · Because Cys is a constituent of the tripeptide antioxidant, enhanced mitochondrial GSH turnover could provide Cys for the generation of Fe-S clusters. Consistent with this, CRISPR-mediated... WebMar 30, 2024 · Because the availability of Cys frequently limits the extent of GSH synthesis, ferroptosis is induced by Cys starvation; e.g. cystine deprivation from the culture medium and the inhibition of xCT by erastin. Thus, the Cys–GSH–GPX4 axis appears to be the primary protective system for coping with ferroptosis [7].

WebJan 23, 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 … WebOct 1, 2024 · Because the availability of free Cys is the major determinant of GSH synthesis, ferroptosis can be readily induced by either Cys starvation (e.g. the deprivation of cystine from the culture medium or the inhibition of xCT by erastin) or GPX4 inhibition.
WebMeanwhile, the starvation/chemodynamic synergistic therapy triggered by UCCG combined with PD-L1 antibody effectively inhibits the growth of primary tumors and cancer metastasis. In addition, the UCNPs in UCCG present upconversion luminescence enhancement, which can be exploited to visualize the reinforced ROS generation in real time. 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 ...
WebAug 18, 2024 · Here, an intelligent anticancer nanoplatform based on an Aza-boron-dipyrromethene dye (denoted as Aza-BDY) is elaborately established for ferroptosis augmented SDT through cysteine (Cys) starvation. After endocytosis by tumor cells, Aza-BDY serves as both a ferroptosis inducing agent and a sonosensitizer for tumor treatment. 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 …
