The genetic material is packaged in the cell nucleus with histone proteins. Modifications of histones determine if a particular area of the genome is active or repressed. We are investigating the roles of a family of histone modifying proteins, the MYST proteins. Mutations in these proteins cause intellectual disability and cancer. The research program will provide knowledge that may become the basis for the development of drugs for the treatment of cancer and neurodegenerative disorders.
In Australia, chronic kidney disease costs >$1 billion per annum and can only be treated by dialysis or transplantation. Your kidney function depends upon what happened during your development as all the functional units of the kidney are made prior to birth from a stem cell population that then disappears. We have found a way to recreate these stem cells from adult cells. In this project, we will optimise this process and investigate whether regenerated stem cells can repair an adult kidney.

The zebrafish is a small tropical fish that is an alternative model to mice for genetic studies. We have used zebrafish to discover genes that are essential for the rapid development of the intestine in the belief that these genes are also essential for tumour growth. We will test whether the loss of RNPC3 (the human version of one of our genes), which is required for the production of a small number of proteins that can suppress the development of cancer, plays a hitherto unappreciated causal r ....The zebrafish is a small tropical fish that is an alternative model to mice for genetic studies. We have used zebrafish to discover genes that are essential for the rapid development of the intestine in the belief that these genes are also essential for tumour growth. We will test whether the loss of RNPC3 (the human version of one of our genes), which is required for the production of a small number of proteins that can suppress the development of cancer, plays a hitherto unappreciated causal role in the development of colon tumours.Read moreRead less
Cancer is linked to mutations in a large variety of genes but how these changes impact on cell behaviour is often unknown. We are using functional genomics in zebrafish to identify genes that are essential for rapid rates of proliferation by intestinal epithelial cells. Seven genes have been cloned so far and our next task is to analyse, using mouse models and human cancer transcriptome analysis, whether any are indispensable for cancer growth and thereby present suitable targets for therapy.

Summary
The cells of the skin play an essential role in development of the mammalian embryo. They are critical for closure of the brain and spinal cord, for forming a protective barrier against infection and noxious stimuli, for preventing excess fluid loss, for repair of defects and wounds, and for the generation of hair. Our laboratory has identified a family of genes that are critical for all these processes. Loss of individual members of the family has different consequences and the aim of this stud ....The cells of the skin play an essential role in development of the mammalian embryo. They are critical for closure of the brain and spinal cord, for forming a protective barrier against infection and noxious stimuli, for preventing excess fluid loss, for repair of defects and wounds, and for the generation of hair. Our laboratory has identified a family of genes that are critical for all these processes. Loss of individual members of the family has different consequences and the aim of this study is to determine the relationship between the genes to further our understanding of the skin and its functions. These studies have direct and important relevance to human conditions such as the congenital birth defects spina bifida and anencephaly, and infant prematurity where the skin is underdeveloped and lacks barrier function. They also have relevance to wound healing and to conditions in which hair growth is affected, such as alopecia. We believe that therapeutic interventions and prenatal diagnostic tests could evolve from these studies.Read moreRead less

Summary
Neurons form an extensive series of connections to relay information across the entire body. It is essential to understand how neurons know to find their way, and form the right connections, in a developing animal. This project will investigate the genes which control formation of neural circuits that are essential for correct movement.

Summary
Exquisite regulation of gene expression is a fundamental principle underlying growth and development of an embryo as well as homeostasis in the adult. Following the identification of hundreds of microRNAs within the genome which act to modulate gene expression, the challenge and the goal of these studies, is to identify individual microRNAs which contribute significantly to bone formation in the developing embryo.
