We further validated the impact of reduced SLC3A2 expression on the sensitivity to ferroptosis in glioma cells through Cell Counting Kit-8 assays, flow cytometry, western blotting, and transmission electron microscopy. Western blot was used to explore how SLC3A2 affects glioma sensitivity to ferroptosis through the AKT\/NF-E2-related factor 2 (NRF2)\/glutathione peroxidase 4 (GPX4) axis. By establishing a subcutaneous xenograft tumor model in BALB\/c-nude mice, we investigated the growth of tumors following the knockout of SLC3A2 in glioma cells.Results Downregulation of SLC3A2 suppressed the malignant phenotype of glioma by blocking the cell cycle and epithelial-mesenchymal transition processes. On the other hand, loss of SLC3A2 not only downregulated SLC7A11 but also prevented the activation of the AKT\/NRF2\/GPX4 axis. These lead to increased accumulation of reactive oxygen species and lipid peroxides, ultimately enhancing the susceptibility of glioma to ferroptosis.Conclusion Our findings suggest that SLC3A2 is an oncogene in gliomas, promoting their occurrence and development. It plays a critical role in ferroptosis resistance through the AKT\/NRF2\/GPX4 axis.<\/jats:p>","DOI":"10.4143\/crt.2024.933","type":"journal-article","created":{"date-parts":[[2025,3,10]],"date-time":"2025-03-10T05:04:07Z","timestamp":1741583047000},"page":"71-94","update-policy":"https:\/\/doi.org\/10.4143\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Elevated
