Solid phase synthesis of side-chain cross-linked peptide oligomers. This research will provide a unique opportunity to investigate the biological pathways and causative factors leading to diseases such as Alzheimer’s disease. Such information will guide the design and development of therapeutic strategies and diagnostic reagents.
The Role of Amyloid Protein Precursor in Mammalian Copper Transport. The knowledge gained from this investigation will help us to develop new medicines for the treatment of debilitating and ever more prevalent age-related neurodegenerative diseases and will help us to illuminate the role of metals in the ageing process itself. Apart from the obvious economic and social benefits in extending the productive lifetime of its citizens, the outcomes of this project have clear commercial applications. ....The Role of Amyloid Protein Precursor in Mammalian Copper Transport.

Apart from the obvious economic and social benefits in extending the productive lifetime of its citizens, the outcomes of this project have clear commercial applications. We anticipate that there will be patents that will ensue from the programme, which will be licensed to Australian interests, and contribute to the national revenue in the biotechnology and pharmaceutical sector.Read moreRead less
Neural Copper Homeostasis: the role of the Alzheimer Amyloid-beta Precursor Protein. Alzheimer's disease (AD) is creating a growing burden upon Australian medical resources. Copper plays an important role in the development of AD, and drugs designed to adjust brain copper levels are being tested for AD treatment and show therapeutic benefits. This project will determine how copper is involved in AD so that more effective drugs can be developed. Focus will primarily be on copper-binding proteins ....Neural Copper Homeostasis: the role of the Alzheimer Amyloid-beta Precursor Protein. Alzheimer's disease (AD) is creating a growing burden upon Australian medical resources. Copper plays an important role in the development of AD, and drugs designed to adjust brain copper levels are being tested for AD treatment and show therapeutic benefits. This project will determine how copper is involved in AD so that more effective drugs can be developed. Focus will primarily be on copper-binding proteins central to AD, including amyloid-beta, and their role in AD development. Upon completion of this project, we expect to better understand neural copper metabolism in health and in AD pathology, with outcomes directly applicable to therapeutic AD intervention.Read moreRead less
The ApoE Interactome in Human Plasma. In this, the post-genome era, the emphasis has switched from the delineation of genome structure to the tremendous task of characterizing the gene products. One of the important aspects evolving in this new era is the design of strategies that enable identification of global protein-protein interactions, defined by the Human Proteome Organisation as the interactome. This, the apoE interactome in human plasma project, will identify novel interactions between ....The ApoE Interactome in Human Plasma. In this, the post-genome era, the emphasis has switched from the delineation of genome structure to the tremendous task of characterizing the gene products. One of the important aspects evolving in this new era is the design of strategies that enable identification of global protein-protein interactions, defined by the Human Proteome Organisation as the interactome. This, the apoE interactome in human plasma project, will identify novel interactions between plasma proteins and apoE, which is a lipid-binding protein genetically linked to age-related diseases affecting more than 500,000 Australians. This project will therefore provide scope for novel treatments and early detection of disease, namely cardiovascular and Alzheimer's disease.Read moreRead less
The Role of Metals in the Biology of the Ageing Brain. Aims
1.To advance basic understanding of the interactions between cellular proteins and biologically important metals
2. To learn how these interactions change as the organism ages
3. To study the pathological results of aberrant metal biology using animal and cellular models of major age-dependent neurodegenerative disease.

2. To learn how these interactions change as the organism ages
3. To study the pathological results of aberrant metal biology using animal and cellular models of major age-dependent neurodegenerative disease.
In a rapidly ageing society, neurodegenerative disorders such as Alzheimer's and Parkinson's diseases will present a medical and economic challenge demanding novel and powerful science. This research will lead both to deeper understanding of the basic mechanisms underlying such disorders and to tools for designing new and effective treatments.

Novel compounds to disrupt protein-protein interactions. Many diseases involve aberrant interactions between proteins. Strategies to inhibit such interactions have potential as tool reagents for biological research but also as new therapies. Most drugs currently used in the clinic are small organic molecules, though these typically are not effective at disrupting protein complexes, hence alternatives are required. This proposal to examine foldamers as a novel strategy for inhibiting protein: pro ....Novel compounds to disrupt protein-protein interactions.

Most drugs currently used in the clinic are small organic molecules, though these typically are not effective at disrupting protein complexes, hence alternatives are required. This proposal to examine foldamers as a novel strategy for inhibiting protein: protein interactions could lead to the development of new drugs for the treatment of diseases where the current traditional approaches have proven ineffective.Read moreRead less
DEEP DRILLING OF THE HUMAN PLASMA PROTEOME. Like turning out city lights lets you see the faint stars more clearly - removal of high abundance proteins from human biofluids allows quantum leaps in biomarker discovery. This project will develop products that remove the biggest obstacle in proteomics - high abundance proteins (city lights). Cheap, efficient and routine removal of abundant proteins will amplify the power of ?cutting edge? proteomic technologies in the discovery of novel biomarkers ....DEEP DRILLING OF THE HUMAN PLASMA PROTEOME.

This project will develop products that remove the biggest obstacle in proteomics - high abundance proteins (city lights). Cheap, efficient and routine removal of abundant proteins will amplify the power of ?cutting edge? proteomic technologies in the discovery of novel biomarkers. This is possible because undiscovered low copy number biomarkers (faint stars) exist in human diagnostic fluids at levels far lower than current proteomic array detection limits.Read moreRead less
Unraveling Fibrosis By Pharmacological Targeting Of The G Protein-coupled Receptor, RXFP1
Funder

Funding Amount
$798,618.00
Summary
Peptides, with their high specificity and low toxicity profiles, are highly attractive alternatives to small molecule drugs. H2 relaxin, a peptide hormone, has a strong potential for treating fibrosis. However, the large size of H2 relaxin makes it difficult and expensive to manufacture. Once administered to patients, it is also quickly degraded. We have developed a small anti-fibrotic relaxin peptide, and propose to understand its mechanism of action and improve its therapeutic indices.

Summary
Relaxin-3 is a neuropeptide that regulates a number of physiological processes, including food intake, suggesting that the relaxin-3 receptor RXFP3 may be a new target for treatment of eating disorders such as obesity. This project will develop new selective and high-affinity ligands for RXFP3, which will be critical pharmacological tools for the preclinical studies and evaluation of this system.
