Summary
Almost one in six men will develop prostate cancer during his lifetime. 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 re ....Almost one in six men will develop prostate cancer during his lifetime. 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
Antibodies are the main line of defence the immune system utilises to target viruses and bacteria that invade our body. Raising the level of antibodies can therefore offer effective protection against disease. However, as antibodies cannot be taken orally (as a tablet) they have to be injected into the blood stream. We aim to overcome this limitation by generating antibodies that survive the passage through the stomach, allowing us to target conditions such as Crohn's disease.

Summary
Antibodies are a relatively new class of drugs that directly target molecular mechanisms of disease. Antibody therapies, such as the breast cancer drug Herceptin, have significantly increased our arsenal of effective therapeutics. In collaboration with G2 Therapies, we will use cutting-edge genetic engineering technology to produce fully human antibodies for the treatment of inflammatory diseases, such as rheumatoid arthritis.
New Therapies Requiring Ultra Large Scale Monoclonal Ab Production In Microalgae

Summary
Monoclonal antibodies target pathogens and molecules with exquisite specificity, and are essential for therapeutics and diagnostics. They are currently made using high-tech/limited-capacity mammalian cell cultures which limit them to low-dose applications. We aim to enable new, high-dose antibody therapies (e.g. antiviral treatments, passive immunisation) via rapid, low-cost, dramatically larger-scale production of valuable medicinal antibodies in a photosynthetic-driven, green algae system.
Developing New Immunotherapeutics Through Studying Immune Effectors In Situ

Summary
The immune system deploys pore forming proteins to clear viral and bacterial infections and to eliminate cancerous cells. The unwanted activities of these molecules, however, results in chronic disease and in transplant rejection. We aim to understand how pore forming immune weapons interact with our own cells, with the goal of using this information to develop new approaches to treat immune driven disease and to improve the success of transplantation therapy.
