FOSL1 and glioblastoma: This review provides a comprehensive overview of canonical and non-canonical NF-κB signaling pathways and their molecular mechanisms in GBM, with a focus on their regulation in glioma stem-like cells (GSCs), interactions with key oncogenic factors (including STAT3, FOSL1, and TRPM7), and roles in maintaining tumor stemness, metabolic adaptation, and angiogenesis.
