We use the fruit fly Drosophila to study how organ size is maintained and how metabolism can shape organ growth.

  • How differentiation is maintained in the developing nervous system
  • How the niche surrounding the neural stem cells affects stem cell behaviour
  • How one specialized cell type in the CNS can become another through trans-differentiation
  • How regeneration is regulated in the CNSs of flies and zebrafish (in collaboration with Patricia Jusuf, UoM)
  • How tumours breakdown fat and muscles during cachexia 
  • How organs communicate with each other to maintain tissue homeostasis

How do neurons maintain their specialised status?

The bidirectional conversion between differentiated cells and stem cells often underlies carcinogenesis. Mechanisms must be in place to prevent differentiated cells from reverting to multipotent stem cells. We have recently discovered that zinc finger transcription factor Nerfin-1 is required to maintain neurons in a differentiated state. In the absence of Nerfin-1, neurons rapidly increase their cellular growth and switch on stem cell markers, then form tumours. The lab is interested in identifying novel transcription factors that regulate this process, and investigate whether these factors are involved in regeneration.

How do dietary nutrients affect the ability of stem cells and stem cell-derived tumours to grow and divide?

The effect of diet on stem cell proliferation and tumour growth is poorly characterised. Using a chemically defined diet together with metabolomic approaches, we are interested in identifying metabolic alterations associated with dedifferentiation, stem cell reactivation and cancer.
