Metabolic Influences on Glioblastoma Survival

Glioblastoma is characterised by profound alterations in cellular metabolism that support rapid proliferation, invasion and resistance to therapy. Tumour cells commonly exhibit enhanced glycolysis even under aerobic conditions, a phenomenon known as the Warburg effect, which facilitates biosynthetic processes and acidifies the microenvironment. In parallel, mitochondrial function is often reprogrammed to balance energy demands and oxidative stress, while lipid biosynthesis and glutamine metabolism provide key substrates for membrane formation and redox homeostasis. Systemic factors such as hyperglycaemia have been linked to poorer outcomes, emphasising the importance of glycaemic control in clinical management. Within the tumour microenvironment, interactions between cancer cells, immune cells and stromal elements further modulate nutrient availability and metabolic crosstalk. Glioma stem cells contribute to recurrence and exhibit distinct metabolic vulnerabilities, including reliance on oxidative phosphorylation and altered reactive oxygen species handling. Therapeutic strategies aimed at targeting these metabolic dependencies—ranging from dietary interventions and biguanide drugs to inhibitors of specific metabolic enzymes—seek to exploit the metabolic plasticity of glioblastoma and improve patient survival.
