Biological Pathways in Glioma [[PI3K]]/[[AKT]]/[[mTOR]] [[Pathway]]: Promotes cell growth, proliferation, and survival. Frequently hyperactivated due to PTEN loss or PIK3CA mutations. RAS/MAPK Pathway: Stimulates cell cycle progression and invasion. JAK/STAT3 Pathway: Drives inflammation, immune evasion, and stemness in glioma cells. Notch and Wnt Signaling: Regulate glioma stem cell maintenance and therapy resistance. Metabolic Reprogramming: Warburg effect: Preferential glycolysis even in oxygen-rich conditions. Increased lipid metabolism and glutamine dependence.
