Multi-omics study reveals a brain radiotoxicity gene signature predicts survival in glioblastoma, highlighting potential targets for neuro-oncology drug repositioning.

Key Points

To assess whether brain radiotoxicity-related genes have prognostic value for glioblastoma patient survival and whether their encoded proteins serve as novel therapeutic targets.
Identified radiotoxicity-related genes using single-nucleotide variants linked to brain radiotoxicity and mapped their functional interactions through protein-protein interaction networks.
Evaluated survival prognostic significance using clinical glioblastoma cohorts from the Glioblastoma Bio-Discovery Portal and validated findings in the Chinese Glioma Genome Atlas dataset.
Performed computational 3D structural analyses to detect clusters of radiotoxic and pathogenic variants within encoded proteins.
Identified the 15CAcBRT signature derived from COMT and APOE functional groups, which predicted glioblastoma survival independently of age, MGMT promoter methylation, and IDH mutation status.
Demonstrated significant expression alterations in the IL6, APOE, and MAOB genes, mapping to biological pathways overlapping cancer and neurodegenerative diseases.
Uncovered 3D variant clusters in radiotoxicity-related proteins that pinpoint candidate targets for neuro-oncology drug repositioning.
