Integrated multi-omics analysis uncovers metabolic subtypes in gliomas, suggesting novel therapeutic pathways.

This research aims to classify glioma-associated macrophages (GAMs) based on their metabolic profiles and assess their clinical significance.
Conducted integrated multi-omics analysis using single-cell RNA sequencing and bulk transcriptome data.
Stratified GAMs by metabolic profiles and correlated findings with patient outcomes.
Developed a prognostic risk model using machine learning algorithms based on GAM metabolic signatures.
Validated gene expression through Western blot analysis in glioblastoma and adjacent normal brain tissues.
Identified four GAM metabolic subtypes, with Detoxification and Energic Macrophages (DEMs) linked to worse survival outcomes.
Machine learning revealed six core prognostic markers associated with high-risk gliomas.
High-risk gliomas showed an immunosuppressive microenvironment with increased immune cell infiltration but reduced T-cell activity.
Integration of model findings with EGFR amplification and IDH1 mutation status improved clinical prognostication.
