Cancer Neuroscience

The Cancer Neuroscience Laboratory aims to translate insights from fundamental neuroscience research and apply these to brain cancer, with a particular interest in glioblastoma, which is the most common malignant primary brain tumour in adults.

Research Focus

At the core of the Cancer Neuroscience Laboratory is a focus on researching cellular quiescence, a reversible hibernation-like state, adopted by brain cancer cells to evade chemotherapy and radiotherapy. By targeting these quiescent cells, we might overcome treatment resistance and improve outcomes for persons with glioblastoma.

To identify novel therapeutic approaches to target quiescence, the laboratory also focuses on understanding how quiescence is regulated in normal neural stem cells in the memory centres of our brains.

  1. Brain cancer – targeting treatment resistant, quiescent cancer stem cell populations through direct targeting, reactivation or suppression strategies.
  2. Modelling – determining the most effective approaches (direct targeting, reactivation, suppression) to target treatment resistant, quiescent cancer stem cell populations.
  3. Metabolism – its impact on quiescent brain cancer stem cells and normal adult neural stem cell populations.
  4. Healthy adult neural stem cell quiescence – identifying novel regulators, with a focus on calcium binding proteins.
  5. Dysfunction of adult neural stem cell quiescence during the aging process, and its possible role in cognitive disorders such as depression and anxiety.

After surgery, tumour tissue is cut into small pieces (~0.5 mm) and cultured for ~1 week. Using these organoids, we investigate how the proportion of quiescent/‘sleeping’ glioblastoma stem cells changes in response to various drug treatments. This information is invaluable in directing us in our mission to improve current treatment strategies for glioblastoma.
