Accumulating evidence indicates that substantial iron accumulation, dysregulation of anti-oxidant defense systems, and elevated levels of lipid peroxidation are present in the brains of AD patients. These alterations create a conducive environment for ferroptosis and are closely associated with neuronal death and cognitive dysfunction. Therefore, targeting ferroptosis-related signaling pathways holds promise as a novel strategy to delay or halt the progression of AD.

While the great potential of ferroptosis in cancer therapy is well-established, and CEP has shown potential antitumor activity, the role of ferroptosis in CEP's impact on GC remains unknown. Our aim in this study is to uncover what role ferroptosis has in the impact of CEP on GC. To investigate this, cell viability was measured by CCK-8 assay, and the effect of CEP on GC cell ferroptosis was assessed by Fe2[Formula: see text], DCFH-DA, and TEM. Integrated transcriptomic analyses revealed the critical pathways involved in CEP-induced ferroptosis, and JC-1, MitoSOX Red, Mito-Tracker, and immunofluorescence staining were used to evaluate mitophagy. The interaction between CEP and PINK1 was further confirmed by molecular docking, CETSA, and DARTS, and a xenograft tumor was used both to evaluate the effect of CEP on GC and to verify its mechanism through immunohistochemistry and western blotting. It was found that CEP could induce ferroptosis in GC cells by inducing an increase in reactive oxygen species, malondialdehyde, and intracellular Fe[Formula: see text] levels, and that it had little effect on normal gastric epithelial cells. Mechanistically, CEP binds directly to RUNX2, PINK1, and FUNDC1 to thereby activate PINK1-mediated mitophagy, prompt FUNDC1 to recruit GPX4 into mitochondria, and ultimately lead to the autophagic degradation of GPX4 and ferroptosis.
