Developing the dunnart as a marsupial model for conservation research. The Australian bushfire crisis of 2020 has taken an enormous toll on our unique wildlife. With no halt in sight to rising global temperatures, more extreme weather events are predicted to increase in frequency and severity. We simply must act now to preserve our unique native mammals in Australia and safeguard against species loss and irreversible declines in genetic diversity. This project will develop methods for the genera ....Developing the dunnart as a marsupial model for conservation research. The Australian bushfire crisis of 2020 has taken an enormous toll on our unique wildlife. With no halt in sight to rising global temperatures, more extreme weather events are predicted to increase in frequency and severity. We simply must act now to preserve our unique native mammals in Australia and safeguard against species loss and irreversible declines in genetic diversity. This project will develop methods for the generation and preservation of stem cells from a range of our most endangered and vulnerable marsupial species. These cells not only allow us to ‘bank’ species and genetic diversity but also provide a route to enabling genetic manipulation, opening up a completely new niche for conservation biology in marsupials.Read moreRead less
Using Drosophila to analyse a master regulator of epithelial homeostasis. Aims:
This proposal aims to use genetic and cell biological analysis of the vinegar fly, Drosophila, to identify the function of the grainyhead gene in intestinal regeneration.
Significance:
This gene is conserved in all animal species and appears to be a master regulator of epithelial tissue development but it is unclear how it can both influence stem cell maintenance and production of functional cell types.
Expected out ....Using Drosophila to analyse a master regulator of epithelial homeostasis. Aims:
This proposal aims to use genetic and cell biological analysis of the vinegar fly, Drosophila, to identify the function of the grainyhead gene in intestinal regeneration.
Significance:
This gene is conserved in all animal species and appears to be a master regulator of epithelial tissue development but it is unclear how it can both influence stem cell maintenance and production of functional cell types.
Expected outcomes:
We will identify a new mechanism that governs tissue development, and introduce new imaging and genetic technologies to the Australian research community.
Benefit:
We expect potential economic and commercial interest in development of new gene analysis tools and biotechnological tissue manipulation applications.Read moreRead less
Defining signals that regulate intestinal stem cells during organ growth. This project will define the key signals that promote cell division in the stem cells which produce the inner epithelial lining of the gut. This fundamental knowledge is of significance as it will provide information about how key signals are delivered to promote repair of injury to this key cell layer. The gut is a vital organ conserved across species that is prone to injury as it is exposed to a very harsh environment of ....Defining signals that regulate intestinal stem cells during organ growth. This project will define the key signals that promote cell division in the stem cells which produce the inner epithelial lining of the gut. This fundamental knowledge is of significance as it will provide information about how key signals are delivered to promote repair of injury to this key cell layer. The gut is a vital organ conserved across species that is prone to injury as it is exposed to a very harsh environment of bacteria and the products of food digestion. The outcomes of this project will provide an understanding of development and regeneration of the epithelial lining and key signals that may augment repair. The future benefits include improved health outcomes for animals and humans and potential economic benefits.Read moreRead less
