WebAn anti-cancer drug, Eprenetapopt, inhibits ISC synthesis by inhibiting cysteine desulfurase activity, thereby inducing ferroptosis and limiting cell proliferation . In conclusion, affecting the synthesis of ISC by inhibiting NFS1 and thus altering the sensitivity of cells to ferroptosis is a potential therapeutic tool to promote ferroptosis in ... WebMar 24, 2024 · Ferroptosis, a concept first introduced in 2012, is an iron-dependent form of non-apoptotic cell death, morphologically characterized by necrotic morphology, dysmorphic small mitochondria with decreased crista, condensed membrane, and a ruptured outer membrane ( Dixon et al., 2012 ).
WebJul 25, 2024 · Ferroptosis, a newly discovered non-apoptotic form of cell death, is essentially iron ion–dependent RCD. Necroptosis is mainly mediated by cytokines (TNF-α, IFN-α, and IFN-γ), Toll-like receptors (TLR3, TLR4, and TLR9), and nucleic acid (DNA and RNA) receptors. WebJul 19, 2024 · A study showed that the knockdown of CARS1 can increase the compensatory transsulfuration pathway to increase cysteine and suppress ferroptosis induced by erastin, which can be resensitized by silencing CBS . Additionally, the ferroptosis-enhancing effect of suppressing CBS has been demonstrated in …
WebSLC7A11 is an essential component of system xc-, and p53 can inhibit cysteine uptake by downregulating SLC7A11 to reduce GPX activity and GSH synthesis, subsequently … WebSep 14, 2024 · Eprenetapopt also inhibits iron-sulfur cluster biogenesis by limiting the cysteine desulfurase activity of NFS1, which potentiates ferroptosis and may restrict cellular proliferation. The combination of eprenetapopt with dietary serine and glycine restriction synergizes to inhibit esophageal xenograft tumor growth.
WebFerroptosis is a new mode of cell death discovered in recent years, which emerged after the discovery that a small molecule compound, erastin and RSL-3, could induce a unique form of cell death in cells. 1, 2 In 2012, this method of death was officially named “Ferroptosis” by Dixon. 3 The research in the past decade has exponentially due to ...
