WebFeb 8, 2024 · Consistently, Tsvetkov et al. showed that depletion of GSH by buthionine sulfoximine promotes copper-induced cell death . Interestingly, several studies have shown that p53 plays a role in GSH biogenesis. p53 was found to transcriptionally repress the expression of SLC7A11, which is critical for the import of the GSH precursor cystine ... WebApr 10, 2024 · Ferroptosis is a disease-relevant and pervasive form of cell death triggered by iron-dependent lipid peroxidation and resulting in membrane rupture. A new study addresses how tension-sensing channels can balance and modulate membrane tension in the context of ferroptotic cell death. Good stories are driven by conflict, tension, and high …
