Scientific Focus
– Metabolic alterations in malignant glioma
– Signal transduction
– Hypoxia-induced cell death
Methods
– Metabolic analysis (consumption of oxygen and glucose, production of lactate)
– Cell death analysis (LDH-release, flow cytometry, apoptosis assays)
– Molecular analysis (quantitative RT-PCR, reporter assays)
