This program aims to understand the biochemical and biological basis of colorectal cancer, a major cause of cancer deaths in Australia. The Chief Investigators have extensive experience in the analysis of the molecular defects in colorectal cancer cells and have already developed new drugs to treat successfully experimental colon tumours in animals.

The Chief Investigators have extensive experience in the analysis of the molecular defects in colorectal cancer cells and have already developed new drugs to treat successfully experimental colon tumours in animals. During this research program, we will explore these systems further, concentrating on the identification of novel inhibitors of colon cancer cell growth, survival and movement. Newly developed instruments and techniques will allow us to identify and detect the critical steps during the development of colorectal cancer and to design potent drugs to fight the disease. We have experience in conducting novel clinical trials in colon cancer and have developed imaging techniques for monitoring the effectiveness and safety of new anti-cancer drugs. Our collective scientific experience and ability to work in the clinic provides a unique opportunity for developing more effective treatments for colorectal cancer patients.Read moreRead less
Analysis Of APC And APC Protein Complexes In Colon Cancer

Funding Amount
$110,786.00
Summary
Colorectal cancer is one of the foremost causes of death in Australia. A defective form of a protein called APC has been shown to be present in more than 80% of colon tumours. How APC contributes to colon cancer is still not known. We aim to determine the function of the APC protein by studying the APC protein and proteins that interact with APC in normal and cancerous colon epithelial cells. We will use cells derived from normal colon epithelium as well as from colon carcinomas. Once we have id ....Colorectal cancer is one of the foremost causes of death in Australia.

We aim to determine the function of the APC protein by studying the APC protein and proteins that interact with APC in normal and cancerous colon epithelial cells. We will use cells derived from normal colon epithelium as well as from colon carcinomas. Once we have identified proteins that interact with APC in normal colonic cells, we will have a more complete understanding of the function of APC and its role in the development of colonic tumours.Read moreRead less
Mechanisms Regulating Mitochondrial Outer Membrane Permeabilisation During Programmed Cell Death

Funding Amount
$306,562.00
Summary
Apoptosis is a form of cell suicide that is vital in human development and health by removing damaged or unwanted cells in a regulated manner. Disturbances in this pathway are known to be the cause of cancers and other diseases. This research will investigate how the pivotal step in cell death, termed mitochondrial outer membrane permeabilisation (MOMP) is regulated.
Structure And Function Of A Cancer-linked Co-regulator Complex

Funding Amount
$1,282,475.00
Summary
We seek to understand the mechanisms by which genes are switched on and off throughout our lifetime. A number of multi-component protein machines are involved in this process but their make-up and mechanism of action is not understood. We will investigate the structure and function of one of these machines that has been strongly linked to cancer.

Developing Novel Molecules That Target Hormone Receptors As An Alternative Cancer Therapy

Funding Amount
$459,867.00
Summary
A promising class of cancer drugs target heat shock protein 90 (Hsp90) and prevent Hsp90 from maintaining its ~100 proteins involved in cell growth. However, all current Hsp90 chemotherapeutics non-selectively target proteins maintained by Hsp90, and induce a cell rescue mechanism involving Hsp70. We describe the development of a novel molecule that will selectively control cell growth and prevent cell rescue via a unique Hsp90 regulated mechanism.
Prion-like Behaviour In Immunity: Super-sized Signalling Platforms?
Funder
National Health and Medical Research Council
Funding Amount
$611,995.00
Summary
Prions have been mostly associated with pathologies but recent discoveries show that prion-like behaviour may be beneficial, enhancing our immune response for example. To test this, we want to systematically explore all human proteins involved in the defence against pathogens, find new prion-like trends and probe their role in the innate immune response.
Endosomal Protein Trafficking Complexes - Therapeutic Targets For Novel Antivirals
Funder
National Health and Medical Research Council
Funding Amount
$543,727.00
Summary
The enzyme Vps4 is a key target for the development of new antiviral drugs targeting a family of enveloped viruses that includes HIV (17,000 cases), Hepatitis B and C (420,000 cases) and Herpes Simplex (type I, II - 1.3 million cases). This project will use high resolution microscopy to investigate the molecular structures that enable infection by these and other Vps4-dependent enveloped viruses.
