Adaptive remodelling of metabolism during liver regeneration

Project Details

Unlike most human organs, the liver exhibits the remarkable capacity to regenerate. The process of liver regeneration is multifaceted, as it requires a complex tissue comprised of multiple cell types to sense the extent of injury and mount an appropriate compensatory regrowth response. However, despite decades of research, the molecular underpinnings of liver regeneration are poorly understood. Consequently, there is a need to better understand the molecular and cellular mechanisms that initiate liver regeneration. Nrf2 is a transcription factor that plays a pivotal role in the cell’s adaptation to stress. We previously identified that stimulation of the Nrf2 pathway upon liver injury facilitates regeneration. Recently, we have pioneered the use of integrated metabolomic and transcriptomic approaches in zebrafish to identify how metabolic remodelling impacts organ growth. We now have preliminary evidence that Nrf2 plays a key role in metabolic remodelling upon liver injury and is required for liver regeneration. Therefore, we are uniquely positioned to examine the mechanism by which Nrf2 remodels metabolism to fuel liver regeneration. This project will deliver new insights into the fundamental biological question of how metabolic remodelling is coordinated with tissue growth and regeneration.

Building on these studies, we currently have research projects that aim to…

  • To determine the role that Nrf2 plays in adaptive metabolic remodelling during regeneration.
  • To characterize a new injury model in zebrafish that recapitulates chronic liver disease.
  • To elucidate the dynamics of liver regeneration at the cellular level by in vivo imaging.
