Microenvironments which support extramedullary hematopoiesis. Tissue regeneration is a breakthrough technology absolutely dependent on knowledge of the stem cells and stromal cells which support differentiation and tissue development. This project investigates the stromal cell types in spleen which can regenerate blood-forming cells in an ectopic tissue site or artificial matrix.
Gain from pain: new tools from venomous animals for exploring pain pathways. This project aims to explore animal venoms for new pain-causing toxins, to determine their structure and mechanism of action. Many venomous animals use their venom defensively and envenomation is frequently associated with rapid and often excruciating pain. In most cases the molecular mechanisms by which they achieve this is unknown. Using biochemical, pharmacological and biophysical techniques, this project expects to ....Gain from pain: new tools from venomous animals for exploring pain pathways. This project aims to explore animal venoms for new pain-causing toxins, to determine their structure and mechanism of action. Many venomous animals use their venom defensively and envenomation is frequently associated with rapid and often excruciating pain. In most cases the molecular mechanisms by which they achieve this is unknown. Using biochemical, pharmacological and biophysical techniques, this project expects to uncover toxins that employ new mechanisms of pain signalling, leading to new insights into pain physiology.Read moreRead less
Understanding the molecular function of plant disease resistance proteins, pathogen effectors and their interaction to protect Australian agriculture. This project aims to understand the processes that enable resistant plants to detect and respond to pathogen attack. The acquired knowledge will form the foundation for durable plant disease resistance measures that can be applied to a wide range of crop diseases in an environmentally sustainable manner.
Directed evolution of enzymes for bioremediation: structure function studies of bimetalloenzymes. We will evolve enzymes that degrade organophosphate pesticides (OPs) that are used in Australian agriculture. Although these OPs were designed to kill insects they are closely related to chemical warfare agents and are known to be toxic to humans. Bacteria have acquired a number of enzymes that degrade some OPs. One such enzyme has been used in field trials demonstrating its potential to degrade OP ....Directed evolution of enzymes for bioremediation: structure function studies of bimetalloenzymes. We will evolve enzymes that degrade organophosphate pesticides (OPs) that are used in Australian agriculture. Although these OPs were designed to kill insects they are closely related to chemical warfare agents and are known to be toxic to humans. Bacteria have acquired a number of enzymes that degrade some OPs. One such enzyme has been used in field trials demonstrating its potential to degrade OP residues. However, many pesticides are not removed rapidly and OP-degrading enzymes require modification(s) if they are to be useful environmental reagents - this can be achieved with directed evolution.

Selectively targeting cancer and infectious disease with fragment-based drug discovery. Finding better compounds as starting points is one of the major challenges for drug discovery research. Fragments are small, weak binding molecules that can be upsized into drug leads with better properties when compared to starting with larger molecules. This project addresses two weaknesses of current fragment based drug discovery (FBDD) methods: first, the limitations associated with screening fragments; a ....Selectively targeting cancer and infectious disease with fragment-based drug discovery. Finding better compounds as starting points is one of the major challenges for drug discovery research. Fragments are small, weak binding molecules that can be upsized into drug leads with better properties when compared to starting with larger molecules. This project addresses two weaknesses of current fragment based drug discovery (FBDD) methods: first, the limitations associated with screening fragments; and second, the quality of commercial fragment libraries. This project anticipates that the findings will establish a commanding role for both mass spectrometry and three-dimensional fragments in advancing FBDD approaches. It also expects to identify fragments with favourable development prospects towards the next generation of therapeutics.Read moreRead less
The use of molecular sponges to inhibit small Ribonucleic acid activity in plants. The deletion of gene activity is the most powerful way to understand gene function; however for genes encoding small Ribonucleic acids (RNAs) no current methodology can efficiently achieve this. Here, we aim to develop a gene silencing technology for small RNA encoding genes, which can be utilised to determine their function and used for biotechnological applications.
Mediator: a new concept for controlled gene expression in plant biotechnology. The Mediator protein complex is a new control point for the activation of all genes in higher organisms and the purpose of this project is to understand how three Mediator subunits regulate disease resistance in plants. The outcomes provide a new concept to direct natural gene expression towards robust crop plants able to cope with climatic variations.
