Summary
The receptor for the peptide hormone relaxin, RXFP1, is being targeted by numerous drug companies for the treatment of cardiovascular disease. However, the lack of molecular detail of how relaxin binds and activates RXFP1 is hindering new drug development. We will determine the structure of the complex of relaxin bound to RXFP1 and the mechanism by which this activates cells. The knowledge gained will aid in the design of new drugs targeting RXFP1 for the treatment of cardiovascular disease.
Glucocorticoids (or 'steroids') are among the most commonly used drugs in the world, chiefly used for inflammatory diseases. However, they have major predictable side effects that have been known for over 60 years. Science has, til now, failed to deliver an alternative that delivers the effects of steroids without the side effects. This application is for funds to support the development of the discovery of the protein known as GILZ towards a treatment to help patients.
Targeting The Complement Cascade: A Novel Therapeutic Strategy For Metastatic Melanoma

Summary
The incidence of melanoma is increasing world-wide, and Queensland has the highest rate of melanoma in the world. Despite advances in treatment, the 3-year survival rate for metastatic melanoma remains extremely low. This project builds on our recent research demonstrating a role for a key component of the innate immune system (complement C3a) in melanoma growth. Specifically we seek to investigate the potential of C3a as a therapeutic target for metastatic melanoma.
Molecular Toxinology Of Australian Box Jellyfish Venoms

Summary
Box jellyfish are an ongoing cause of illness and death for coastal communities and tourist regions in northern Australia. As well as creating a significant medical problem, the resulting closure of beaches during boxjellyfish 'season' results in an enormous loss of tourism income and threatens Australia's reputation as a safe destination. The jellyfish venoms contain toxins with potentially lethal effects on humans.

As well as creating a significant medical problem, the resulting closure of beaches during boxjellyfish 'season' results in an enormous loss of tourism income and threatens Australia's reputation as a safe destination. The jellyfish venoms contain toxins with potentially lethal effects on humans. For the first time, using pure venoms derived from the specialised stinging cells (i.e. nematocytsts), we will isolate and characterize the major toxins from four species of box jellyfish. Their mechanism of action will be determined and the effect of various treatments such as antivenom will be investigated. This will also lead to the discovery of toxins with potentially novel targets and modes of action and increase our understanding of proposed treatments and prevention of stings.Read moreRead less
