Molecular hallmarks of androgen receptor targeting in prostate cancer. There is a critical need in oncology drug development for better biomarkers of response to prostate cancer therapies, clinically to assist with treatment decision making, and pre-clinically to facilitate translation of emerging agents into clinical practice. Using a unique explant culture model, this project will identify protein and lipid markers that can be used to accurately and reliably assess response to androgen recepto ....Molecular hallmarks of androgen receptor targeting in prostate cancer. There is a critical need in oncology drug development for better biomarkers of response to prostate cancer therapies, clinically to assist with treatment decision making, and pre-clinically to facilitate translation of emerging agents into clinical practice. Using a unique explant culture model, this project will identify protein and lipid markers that can be used to accurately and reliably assess response to androgen receptor (AR)-targeting therapies in human prostate tumours. The identification and functional assessment of these biomarkers will identify those that can be used as surrogate endpoints in clinical trials, facilitate earlier approval of investigational agents and lead to improved options for therapeutic management of prostate cancer.Read moreRead less
Response of Proteins to External Non-Ionising Radiation: an Experimental and Computer Modelling Investigation. The expanding use of digital technologies such as mobile phones has led to major health concerns about the effects of non-ionising pulsed radiation exposure which has been shown to produce instantaneous temperature rises undetectable by normal thermometry. The health implications of exposure are not understandable without establishing molecular mechanisms by which pulsed microwaves can ....Response of Proteins to External Non-Ionising Radiation: an Experimental and Computer Modelling Investigation. The expanding use of digital technologies such as mobile phones has led to major health concerns about the effects of non-ionising pulsed radiation exposure which has been shown to produce instantaneous temperature rises undetectable by normal thermometry. The health implications of exposure are not understandable without establishing molecular mechanisms by which pulsed microwaves can cause biological effects. We aim to establish methods for studying the molecular mechanisms of protein structural and energetic changes occurring due to non-ionising radiation. The results will help our industry partner to design specific drugs as well as formulate a scientifically based standard for microwave utilisation.Read moreRead less
How SEP-like genes determine cereal inflorescence architecture. This project aims to understand the morphological diversity of inflorescence architecture between cereal crop species. To do so, this project will identify functions and analyse the regulatory networks of conserved SEPALLATA genes (SEPs). This will enable them to determine cereal inflorescence morphogenesis of rice (branching) and barley (non-branching), representing the most important cereals. Identifying and understanding rice and ....How SEP-like genes determine cereal inflorescence architecture. This project aims to understand the morphological diversity of inflorescence architecture between cereal crop species. To do so, this project will identify functions and analyse the regulatory networks of conserved SEPALLATA genes (SEPs). This will enable them to determine cereal inflorescence morphogenesis of rice (branching) and barley (non-branching), representing the most important cereals. Identifying and understanding rice and barley SEPs, their direct targets and interactors, and how they regulate inflorescence branches and spikelets in both species is expected to provide evolutionary and developmental insights and targets to improve for crop yield. A molecular understanding of the regulatory network that underpins inflorescence shape and grain number will advance fundamental biology, and could form the basis for significant yield improvements by manipulating key points in the developmental pathway.Read moreRead less

Protecting cereal grain development at high temperatures. This project aims to investigate new temperature-responsive factors that regulate cereal grain development to protect grain production under heat stress. The new research will leverage international collaborations with access to cutting-edge genetic and technological resources, and refine novel X-ray imaging techniques in Australia, to observe how temperature affects flower structure and function in barley and rice.

This project aims to investigate new temperature-responsive factors that regulate cereal grain development to protect grain production under heat stress. The new research will leverage international collaborations with access to cutting-edge genetic and technological resources, and refine novel X-ray imaging techniques in Australia, to observe how temperature affects flower structure and function in barley and rice. Favourable mutations that optimise plant yield and fitness will be defined and explored in other, more complex, cereals such as wheat. Expected outcomes will be fundamental breakthroughs in understanding how plants respond to, and buffer, the effects of heat to lead to translational breeding strategies that bolster grain yield.Read moreRead less
ARC Centre of Excellence in Plant Cell Wall Biology. The ARC Centre for Plant Cell Wall Biology will define the regulatory mechanisms that control molecular, enzymic and cellular processes involved in the synthesis, deposition, re-modelling and depolymerisation of cell wall polysaccharides of cereals and grasses.

The ARC Centre for Plant Cell Wall Biology will define the regulatory mechanisms that control molecular, enzymic and cellular processes involved in the synthesis, deposition, re-modelling and depolymerisation of cell wall polysaccharides of cereals and grasses. Plant cell walls represent the world's largest renewable carbon resource, but the regulatory mechanisms responsible for their synthesis and assembly are not understood. Key distinguishing features of the Centre will be the international, integrative, and multidisciplinary approach towards addressing major questions in plant biology, its strategy to leverage ARC funding, and its linkages with potential national and international end-users of the fundamental scientific discoveries.Read moreRead less
Multifunctional channels as key components of biotrophic interfaces in legumes. In legumes there are two types of membrane interfaces between different genomes that are critical for growth and yield (nitrogen fixation and seed loading), which require cell-signalling pathways to control nutrient exchange. The membranes of these interfaces contain specialised proteins that form multifunctional channels through which water, uncharged molecules and electrolytes move. These channels are likely to be ....Multifunctional channels as key components of biotrophic interfaces in legumes. In legumes there are two types of membrane interfaces between different genomes that are critical for growth and yield (nitrogen fixation and seed loading), which require cell-signalling pathways to control nutrient exchange. The membranes of these interfaces contain specialised proteins that form multifunctional channels through which water, uncharged molecules and electrolytes move. These channels are likely to be responsible for supporting the bulk of transported nutrients and in controlling their exchange. We aim to discover how these channels function in nitrogen fixation and seed loading with a view to developing new technologies that may enhance crop productivity.Read moreRead less

Summary
MicroRNAs function as regulators of gene expression. It is becoming appreciated that microRNAs are frequently expressed as variants with subtly different sequences. We find here that variation in one important cancer-associated microRNA, miR-222, promotes differences in the behaviour of cells expressing them. This work seeks to understand how microRNA variation confers such properties to cells, to identify the genes miR-222 variants regulate, and to examine how widespread it is that microRNA var ....MicroRNAs function as regulators of gene expression.
