Glioblastoma (GBM) is characterized by significant cell state plasticity, which contributes to therapeutic resistance and tumor progression. Recent studies have highlighted the role of BRD2 in regulating NF-κB-mediated mesenchymal transition, suggesting that targeting this pathway may enhance therapy response (ref: Vadla doi.org/10.1093/neuonc/). Additionally, Bourmeau et al. utilized fluorescent reporters to monitor the plasticity of proneural and mesenchymal subtypes in real-time, revealing that hybrid glioblastoma cells exhibit resistance to therapy and are dependent on nuclear import mechanisms (ref: Bourmeau doi.org/10.1093/neuonc/). Doroszko et al. further elucidated the relationship between GBM cell differentiation states and invasion routes, identifying biomarkers that could be targeted to modulate invasive cell states (ref: Doroszko doi.org/10.1038/s41467-025-61999-1/). Liu's research identified a metabolic-epigenetic axis involving the mitochondrial calcium uniporter that supports glioblastoma stem cell survival, indicating potential vulnerabilities for therapeutic targeting (ref: Liu doi.org/10.1158/0008-5472.CAN-25-0419/). Overall, these studies underscore the complexity of GBM plasticity and the need for innovative strategies to overcome therapeutic resistance.
