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.

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

Summary
Within each cell proteins are synthesised and destroyed with delicate control to ensure the cell functions appropriately. Excess proteins are removed by specific degradation pathways, which are often misregulated in cancer. This project aims to further our understanding of misregulated protein degradation in cancer. The knowledge gained will assist with the development of cancer targeting drugs specific to protein degradation pathways that become misregulated in tumour formation.

Summary
The increasing prevalence of Type 1 and Type 2 diabetes demands better treatments. Our Project is based on a fascinating discovery by our international team of CIs of a new type of insulin within marine organisms that could form the basis of a novel diabetes therapeutic. Within our Project we will exploit this discovery to develop a new class of ultra-rapid-acting therapeutic insulins.
Snake envenoming is a neglected tropical disease and results in numerous deaths, psychological problems and economic burden. Antivenoms aren't readily available in resource poor countries. The CRE will investigate the effects of venom and antivenom to improve understanding of human envenoming. It will also develop tests for early diagnosis of envenoming and undertake clinical trials of antivenom. These studies will be translated back into clinical practice to improve treatment of snake bites.
Snakebite is a worldwide health problem, causing some 100,000 deaths per year. We have preliminary evidence that application of nitric oxide-releasing chemical to the skin presents a novel approach to first aid treatment of venomous bites. The method has the advantage of being simple and reliable and could save lives applied by itself or as an adjunct to pressure bandaging with immobilisation (PBI).
