IDH1 and glioblastoma: This study reports a novel stratification of IDH wild-type GBM patients based on high (M-H) or low (M-la and M-Lb) expression of core matrix protein encoding genes through analysis of multi-modal molecular and clinical datasets from diverse sources (TCGA, IvyGap, CPTAC, GLASS, and GBM single-cell transcriptomics).
