Targeting a unique glutamine dependence in brain tumour stem cells: A novel therapeutic option for GBM
FY 2016-17
Summary
GBM is the most common and most aggressive adult brain cancer. It is thought that therapeutic resistance and tumour recurrence may be due, in part, to brain tumour stem cells (BTSCs) within these tumours. We have over 100 BTSC lines and have utilized these lines to study GBM biology and for the development of novel, experimental therapeutics. We have recently found that more stem-like populations in BTSCs have different metabolic requirements favouring glutamine over glucose. We aim to use this glutamine dependence to develop experimental therapeutic strategies targeting BTSCs. Our results also show an inverse correlation between the STAT3 pathway activity in BTSCs and this dependence on glutamine metabolism. We plan to combinatorially target these two pathways to help achieve greater therapeutic efficacy in BTSCs.
