Summary
Sphingosine kinase is a protein that when dysregulated is involved in cancer development and progression. We have recently made a substantial breakthrough in this area by identifing a naturally occuring variant of sphingosine kinase that is constantly activated and has an enhanced ability to induce cancer. In this study we will examine and target this form of sphingosine kinase as a potential therapeutic intervention in cancer.
The Role Of Protein Glycosylation In The Malaria Parasite

Summary
The parasites that cause malaria have unique proteins on their surface that are essential for infection of humans. These proteins are useful for making vaccines to train our immune system to recognize and block infection by the malaria parasite. Our latest research has shown that these proteins are modified with sugars that enhance parasite virulence. We are studying these modifications more closely to facilitate the development of improved malaria vaccines.
Characterization Of The Type IX Secretion System In Porphyromonas Gingivalis

Summary
Periodontitis is associated with the keystone pathogen Porphyromonas gingivalis. We have identified a novel protein secretion machine comprised of at least 12 components in P. gingivalis which transports the bacterium's major virulence factors to the cell surface and attaches them to the outer membrane. We aim to determine the spatial arrangement and specific role of each of these 12 components and thereby provide targets for future treatments against this disease.
Characterising Protein And Membrane Changes In Age-related Cataract Lenses.

Summary
Cataract is the major cause of blindness worldwide. At present the only treatment for cataract, is surgery. This, however, is associated with complications (e.g. posterior capsule opacification), is expensive (a major component of the Health budget) and cannot keep pace with the incidence of cataract in developing nations. In addition, due to the greying of the community , this problem will be of increasing importance in the future. For prevention, we need to understand why cataract develops.
Role Of Sirtuins In The Regulation Of The Carcinogen Metabolising Arylamine N-acetyltransferases

Summary
This project will investigate critical biochemical pathways that regulate metabolic differences in normal and cancer cells. By understanding how these processes differ, novel approaches for detecting and managing cancer cell proliferation in humans may be achievable.
Most diseases are much more common in the elderly. The reasons are poorly understood. We have evidence that the most common eye diseases, cataract and presbyopia, are due to the fact that the large molecules that make up the lens do not turnover. In lenses of older people proteins, which make up the bulk of the transparent tissue, become degraded. It turns out that very long lived proteins are quite common in the body. This proposal seeks to determine what role degradation of these ancient prote ....Most diseases are much more common in the elderly. The reasons are poorly understood.

Protein Prenylation And Inflammation: New Insights Into The Pathophysiology And Treatment Of Mevalonate Kinase Deficiency
Funder
National Health and Medical Research Council
Funding Amount
$715,755.00
Summary
This project is focused on a genetic, potentially fatal, inflammatory disease that appears in infancy. We have developed a new way of detecting the underlying defect as well as the first animal models that have the same genetic mutations and mimic the disease. With these revolutionary new approaches, we will discover the exact cause of the inflammation, test a new way of diagnosing the disease, and identify new and better therapies that treat the underlying cause rather than just the symptoms.
Understanding Age-related Protein Aggregation. The Mechanism Of Cataract And Its Prevention
Funder
National Health and Medical Research Council
Funding Amount
$709,333.00
Summary
Cataract arises from clouding of the eye lens due to the aggregation of crystallin proteins whose high concentration and close packing facilitate lens transparency. This proposal will investigate crystallin structure and interactions to understand the reasons for cataract formation and its prevention via the design of aggregation inhibitors. The results will facilitate the development of drugs to prevent cataract and other related protein aggregation diseases, e.g. Alzheimer’s and Parkinson’s.
Investigating Drug Treatments For A Machado Joseph Disease Using Transgenic Zebrafish

Funding Amount
$443,425.00
Summary
Machado Joseph disease (MJD) is a hereditary neurodegenerative disease that causes problems with a patient’s co-ordination and movement, leading to paralysis and death. Although the disease affects patients throughout the world, it is most common within Aboriginal communities of Arnhem Land in the Northern Territory. This project seeks to identify a drug treatment for the disease by examining the effect of relevant drugs on zebrafish genetically modified to have the human gene that causes MJD.
