Scientific Focus
Mechanisms of programmed cell death, acute and chronic cns damage, neuronal stress signalling, physiological and pathophysiological roles of the amyloid precursor protein and its family members, mitochondrial control of cell death, target-specific therapies for the treatment of brain tumors, oncogenic signalling pathways, autophagy in health and disease, mechanisms of tumor cell migration and invasion.
Methods
Assays for detection of apoptosis (Caspase assays, FACS Annexin/propidium iodide, measurement of mitochondrial membrane potentials), autophagy and mitophagy (LC3 conversion and translocation, autophagic flux of GFP-LC3-RFP, FACS MTG, MTDR, Lysotracker) and cell viability (MTT assay), cultivation of primary neurons, organotypic cultures, in vitro hypoxia/ischemia models, reporter gene assays, shRNA/siRNA techniques, CRISPR/Cas, lentiviral gene transfer, live cell imaging, in vivo brain tumor models, in vitro models for cell migration and invasion, glioma stem-like cell models.
