Summary
A major limitation to the success of targeted therapies in cancer is the fact that we have few if any tools to study in detail their mechanism of action within cancerous and normal cells. If we were able to visualise these drugs within cells and precisely characterise the proteins, DNA and RNA within a cell that interact with these therapies we will be able to identify strategies that can optimise their efficacy and reduce the side-effects of these treatments.
VCAM-targeted Delivery Of Recombinant CD39 To The Endothelium Is Antithrombotic, Antiinflammatory And Ameliorates Ischaemia Reperfusion Injury.

Summary
Blockage of arteries with clots leads to heart attacks and strokes. Reestablishment of blood supply by clot-busting drugs or mechanical interventions paradoxically causes further organ injury. This is due to toxic chemicals generated by inflammatory processes and free oxygen radicals. We have created an unique drug that selectively targets blood vessels that are injured by process. The drug will deliver blood-thinning activity and reduce inflammatory stress selectively at the site of need.
A Pharmacological Targeting Approach Implementing Albumin As A Carrier Of A Novel Chemotherapeutic

Summary
New drugs for cancer therapy are essential to develop that overcome resistance to standard chemotherapeutics. We have developed potent anti-cancer chelators that bind to the abundant plasma protein, albumin. Our studies showed increased tumour cell uptake of the chelator, Dp44mT, mediated by albumin. We will elucidate the mechanisms of their albumin-mediated uptake, with the aim to implement albumin nanoparticles as carriers of novel chelators to selectively target tumours.
Inflammation And Oxidative Stress In Emerging Psychotic And Mood Disorders

Summary
We are conducting four large clinical trials testing anti-inflammatory treatments like ?-3 PUFAs and aspirin in young people who are at high-risk for psychosis or have depression. This proposal adds an important component to this research by investigating inflammatory and oxidative stress markers. We aim to determine if the investigated biomarkers predict the course of illness and response to treatments. The findings will facilitate early intervention and targeted treatment.
Molecular Profiling Residual Disease From Early Stage HER2 Positive Breast Cancer Treated With Neoadjuvant Chemo- And Anti-HER2 Therapy

Summary
Chemotherapy given prior to surgery can often inform us if a breast tumour is sensitive or resistant to therapy by the amount of disease remaining at time of surgery. We have further shown that the immune response is also important in these patients. In this study we propose to analyse the tumour samples that remain after chemotherapy in order to understand possible resistance mechanisms as well as how the immunity influences survival of HER2-positive breast cancer patients

Summary
Gum disease (periodontitis) is an inflammatory disease caused by bacterial pathogens that is the major cause of tooth loss in adults. It is also associated with systemic diseases such as cardiovascular disease. In this study we will develop novel peptide-based therapeutics to inhibit the proteases that enable these bacteria to cause disease.
Colorectal cancer is the third leading cause of cancer related death in Australia. While there are now a number of treatment options for patients with colon cancer, there is significant variability in response among patients to individual drugs. This NHMRC project grant will seek to identify genetic markers which predict the likelihood of a patient responding to a specific therapy. This will enable individual patients to be treated with the drug most likely to be of benefit to them.
Chemotherapy causes a massive depletion of blood-producing cells in the bone marrow. This results in a condition known as myelosuppression that has many harmful side effects for cancer patients. Our aim is to develop a safe and inexpensive approach that will specifically protect the blood-producing cells from chemotherapy but leave the cancer cells sensitive. If this treatment shows significant benefits in mouse models of cancer then the establishment of clinical trials will be initiated.
During injury or infection, our body’s immune system protects us by launching inflammation. But uncontrolled inflammation drives common diseases such as cancer, diabetes and Alzheimer’s. This project will reveal how the body deactivates inflammasomes - protein complexes at the heart of inflammation and disease – so we can design better strategies for treating patients with inflammation-driven disease.
EEF1A1 Is Critical For HIV-1 Reverse Transcription And Replication

Summary
The project will investigate interaction between the AIDS virus, HIV-1, and the human cell it grows in specifically focusing on a human protein called eEF1A. Our research shows eEF1A is required for HIV-1 growth by regulating a step in the virus life cycle called reverse transcription. The goal of this project is investigate how interaction with eEF1A helps HIV-1 reverse transcription and to find drugs that block HIV-1 interaction with eEF1A.
