KDM1A/HDAC2-driven epigenetic dysregulation maintains a drug-resistant, relapse-initiating glioblastoma cell niche at the peri-tumoral margin.
Glioblastoma (GBM) is among the most aggressive primary brain tumors, marked by rapid proliferation, therapeutic resistance, and profound intratumoral heterogeneity. Epigenetic regulators such as lysine-specific demethylase 1A (KDM1A) and histone deacetylase 2 (HDAC2) are aberrantly expressed in resistant GBM subpopula...
