Summary
We inherit our mitochondrial DNA from our mothers. Mutations to mitochondrial DNA can give rise to severely debilitating diseases that can be passed from one generation to the next. The aims of this application are to understand how mutant mitochondrial DNA is selected for; when it affects energy production during development; and to ensure that certain reproductive strategies do not result in the adverse transmission of mitochondrial DNA that will affect subsequent generations.
GTPase Regulation Of The Hippo Organ Size-control Pathway

Summary
The Hippo pathway is a key regulator of tissue growth. It was first discovered in vinegar flies and plays a similar role in mammals. We aim to define the mechanism by which two proteins, Pix and Git, control tissue growth by regulating the Hippo pathway. These studies will be performed in flies. Our studies will shed light on how tissue growth is controlled, and have the potential to inform the way that we treat human cancers and tissue growth disorders.
Tissue-dependent Proregenerative Mechanisms In Adult Vertebrates

Funding Amount

Summary
This proposal addresses how immune cells participate in regeneration of damaged organs in adult zebrafish. Unlike mammals, zebrafish have a remarkable capacity to regenerate their various body parts in adulthood, providing a model to understand how regeneration capacity might be induced in humans. The proposed study will define mechanisms of immune-mediated regeneration that could provide new cellular and molecular targets for stimulating replacement of damaged organs in the human injury setting
Understanding The Mechanisms That Regulate Spleen Organogenesis

Summary
Spleen is a organ with regenerative capacity but the cells driving this have been largely unexplored. A cell-type essential for spleen tissue formation was recently discovered, termed a spleen organiser cell. We are now are attempting to understand where these cells originate from, what cells they develop into, and which genes are important for spleen regeneration. These findings will advance fundamental knowledge of spleen development and lead to better strategies for spleen transplant therapy.
Identification And Characterisation Of Genes Required For Cardiac Morphogenesis

Summary
The heart is the first organ to become functional as an embryo forms, reflecting its critical role in sustaining life. Mistakes that occur as the heart develops have devastating consequences for an individualÍs survival and health. We have identified two zebrafish mutants with heart defects and, using sophisticated imaging and genetic studies, will investigate these defects and identify the genes responsible. This research will improve our understanding of correct and diseased heart formation.
