PRMT1 regulates glioblastoma stemness and immunosuppression via nitric oxide metabolism: Multi-cohort analysis and experimental validation
Abstract
Glioblastoma is the most common primary malignant brain tumor with poor prognosis. The immunosuppressive microenvironment and cancer stem cells (CSCs) drive therapeutic resistance. The role of nitric oxide (NO) metabolism in coordinating glioma stemness and immune evasion remains unclear. We performed multi-omics analysis using CGGA, TCGA, and Rembrandt datasets (n=1,500) and single-cell RNA sequencing (n=65,655 cells). PRMT1 was identified as a key NO metabolism-associated prognostic gene through Cox regression and LASSO modeling. Validation used glioma cell lines, patient-derived GSCs, and orthotopic mouse models. NO metabolism activity increased with glioma grade and correlated with poor survival (p
