Summary
Vaccines are among the most effective medical interventions. The recent discovery that cholera toxin, when applied to the normal skin of humans and laboratory animals, stimulates powerful and protective immune responses to itself, and to other proteins has opened up the possibility of needle-free vaccines in the form of skin patches. How CT brings about this effect is currently unknown. We have discovered that the immune stimulating effect of CT depends upon the production of an immune protein ( ....Vaccines are among the most effective medical interventions. The recent discovery that cholera toxin, when applied to the normal skin of humans and laboratory animals, stimulates powerful and protective immune responses to itself, and to other proteins has opened up the possibility of needle-free vaccines in the form of skin patches. How CT brings about this effect is currently unknown. We have discovered that the immune stimulating effect of CT depends upon the production of an immune protein (cytokine) called tumour necrosis factor (TNF). TNF is known to activate specialised immune cells within the skin (Langerhan's Cells ) and we hypothesise that the interaction beween CT and LC via TNF is the pathway to the potent immune response. In this project we propose to investigate the cells and molecules involved in the immune effects of CT in the skin with a view to the development of new skin based vaccine strategies.Read moreRead less

Summary
We have discovered two molecules from pineapple stems that show anti-tumour activity in laboratory studies. One molecule, called ananain, blocks a cancer causing protein called Ras, which is defective in approximately 30% of all cancers. The other molecule, called canizain, stimulates the bodies own immune system to target and kill cancer cells. The proposed research seeks to provide proof of concept of the use of ananain and canizain as drug development targets.

The other molecule, called canizain, stimulates the bodies own immune system to target and kill cancer cells. The proposed research seeks to provide proof of concept of the use of ananain and canizain as drug development targets. Once this early proof of principle phase has been completed, we believe that ananain and canizain would be extremely attractive targets for further investment by a major pharmaceutical company.Read moreRead less

Summary
In the next few years cancer is projected to become the leading cause of death in industrialised countries. Cancer chemotherapy currently relies on destruction of tumours by toxic drugs that indiscriminately kill all cell types, resulting in side effects that limit treatment. In the 21st century new cancer drugs will more effectively destroy malignant tumour cells without damaging normal cells.

Cancer chemotherapy currently relies on destruction of tumours by toxic drugs that indiscriminately kill all cell types, resulting in side effects that limit treatment. In the 21st century new cancer drugs will more effectively destroy malignant tumour cells without damaging normal cells. The R and D herein will value-add to our discovery of a new class of potent and orally active anti-tumour drugs that possess unusually high selectivity in acting on cancer cells without killing normal human cells. Our current proof of concept will be turned into a drug development candidate that will improve our negotiating position with commercial partners.Read moreRead less
Developing Novel Anti-cancer Agens By High Throughput Chemical Screens For Small Molcules That Modulate The Pro-survival
Funder
National Health and Medical Research Council
Funding Amount
$125,000.00
Summary
Cancer is the second commonest cause of deaths in our community. Unfortunately, treatment often fails or causes unwanted side effects. This proposal seeks to discover and develop a novel class of anti-cancer drugs that act by directly activating programmed cell death (apoptosis). The Bcl-2 proteins are key regulators of cell death and by exploiting knowledge about these prime targets for cancer therapy, we aim to discover drugs that are potentially of considerable medical and commercial value.
Pre-clinical Evaluation Of Nano-membrane Dressings To Promote Wound Healing
Funder
National Health and Medical Research Council
Funding Amount
$188,600.00
Summary
This project will investigate whether a novel type of wound dressing can promote faster wound healing and reduce scarring. Time taken to heal is one of the best predictors of whether a wound will heal with significant scarring. The faster wounds heal the better. We have identified a new dressing with specific nano-scale pores that may promote faster healing. This dressing will be tested in the best model of human wound healing with the potential to progress to clinical trials if successful.

Every year, around 10,000 Australian men are diagnosed and more than 2,500 die of the disease, making prostate cancer the second largest cause of male cancer deaths after lung cancer. The research progress made on prostate cancer over the past 10 years has been encouraging. However the five-year survival rate remains low. There is a vital need to develop new methods to treat this disease. An exciting principle has emerged recently with the use of monoclonal antibodies (Mabs) such as Herceptin (a humanised anti-HER2 Mab), which is now being widely used to treat breast cancer. We produced 2 Mabs to Pim1, which significantly inhibited prostate cancer cell growth in mouse prostate cancer model. Pim1 is a novel oncoprotein, a biomarker for the treatment of prostate cancer as it overexpresses in more than 90% of prostate cancer, but not or less expressed in normal prostate, demonstrated by genearrays and immunohistochemical staining. Pim1 plays an important role in cell survival, proliferation and metastasis. Pim1 is a novel target, and the anti-Pim1 Mabs may be of value for the cancer therapy in humans. However, the murine Mab can not be repeatedly used in human because human would produce anti-mouse antibody response, and the murine Mab would be rapidly removed from circulation, which will greatly limit the therapeutic potential of the Mabs. Fortunately, the problem can be overcome by the use of hybrid chimeric antibodies. In this study, we are going to use chimeric technology to humanise the anti-Pim1 Mab and test them in vitro and in mouse model for the preclinical studies. We have had patent to protect our finding, and we are confident to produce mouse-human chimeric Mab for the future clinical trial as we have proper knowledge, techniques. We are also optimic for the future clinical trial as we have the experiences on commercialisation.Read moreRead less

Summary
Chronic leg ulcers are a common, painful and costly reality for many Australians, impacting on sufferers' mobility, social interactions and overall quality of life. This research is directed at developing a novel cost-effective wound dressing for treatment of this condition. This will be achieved through neutralising the ulcer's toxic proteolytic environment through an interactive wound dressing. This then will allow the body's own cells to promote wound healing.

Summary
New therapies to treat cancers and inflammatory diseases are urgently required. Our aim is to develop a new treatment for cancer and inflammation, by blocking the chemokine receptor CXCR2 which is central to angiogenesis (blood vessel growth) and inflammation. We have produced a highly effective monoclonal antibody (mAb) inhibitor of CXCR2, that is suitable for preclinical and clinical development. The project aims to examine the efficacy of this mAb in mouse tumour models and inflammation.
