Inhibition of FOXM1 Leads to Suppression of Cell Proliferation, Migration, and Invasion Through AXL/eEF2 Kinase Signaling and Induces Apoptosis and Ferroptosis in GBM Cells

Glioblastoma multiforme (GBM) is an aggressive and molecularly heterogeneous brain cancer with a poor prognosis. Despite advancements in standard-of-care therapies, including surgery, radiotherapy, and temozolomide (TMZ), the median survival remains approximately 15 months, with a 5-year survival rate of less than 10%. We and others have demonstrated that FOXM1 is a critical oncogenic driver of GBM cell proliferation. However, the role of FOXM1 and its interaction with other oncogenic signaling pathways in GBM remains incompletely understood. In this study, we identified FOXM1, AXL, and eEF2K as highly upregulated oncogenes in GBM patient tumors. We demonstrated, for the first time, that FOXM1 directly interacts with AXL and eEF2K, regulating their expression and promoting GBM cell proliferation, migration, and invasion. Knockdown of these genes disrupted cell proliferation, spheroid formation, migration, and invasion, and induced apoptosis and ferroptosis. Additionally, inhibiting the FOXM1–AXL/eEF2K signaling axis sensitized GBM cells to TMZ, further enhancing apoptotic and ferroptotic responses. These findings highlight the critical role of the FOXM1–AXL/eEF2K signaling pathway in GBM progression and suggest that targeting this axis may offer a novel multitargeted therapeutic strategy in GBM.
