The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

CHARACTERISATION OF THE PROSTATE ANDROGEN-RESPONSE PROGRAM USING COMBINED TRANSCRIPT AND PROTEIN EXPRESSION PROFILING

Summary
Carcinoma of the prostate exhibits a wide range of biological variation influenced by genetic, racial, environmental, and other as yet undefined factors. For 1997 the Australian Bureau of Statistics estimates revealed that 27% of all deaths (> 34,000) were due to cancer. Among males, the second leading cause of death (13%) was prostate cancer. The development and progression of human prostate cancer is driven by the accumulation of genetic changes and influenced by a multitude of currently un ....Carcinoma of the prostate exhibits a wide range of biological variation influenced by genetic, racial, environmental, and other as yet undefined factors. For 1997 the Australian Bureau of Statistics estimates revealed that 27% of all deaths (> 34,000) were due to cancer. Among males, the second leading cause of death (13%) was prostate cancer. The development and progression of human prostate cancer is driven by the accumulation of genetic changes and influenced by a multitude of currently unknown events. In addition, a genetic predisposition to certain environmental elements may also provide susceptibility to the onset of prostate cancer. Inherent in identifying the mechanisms leading to prostate cancer is defining the molecular factors involved in the biological processes that influence the development, progression, and treatment of this malignancy. This proposal aims to address the lack of fundamental knowledge relating to the androgen hormone mediated molecular pathways through a comprehensive approach using genomic (DNA), transcribed (RNA) and translated (protein) information that will define the components of the androgen regulated events; i.e. identify the proteins and genes directly or indirectly regulated by androgenic hormones and their cognate receptors. Importantly we will apply technologies that can detect molecular changes in the cell without preconceived ideas about which information will be most valuable to monitor or which technologies will have the greatest impact. We anticipate that the characterisation of the prostate androgen-response will not only provide fundamental knowledge concerning androgen-mediated mechanisms of growth and cellular differentiation, but will also provide a molecular framework for therapeutic intervention through the identification of novel therapeutic targets suitable for a variety of interventions ranging from dietary modification to immunological and gene-therapy approaches.Read moreRead less
Structural Biology Of Cytokine Receptor Signalling
Funder
National Health and Medical Research Council
Funding Amount
$3,988,996.00
Summary
This Program will be focused on a group of protein hormones and their receptors, implicated in blood cell cancers and inflammatory diseases and for which current treatments are inadequate. We will determine the mechanism of receptor activation and in particular will seek to link different forms of receptor assembly to different functions. This information will help us develop new drugs with more specificity for certain hormone functions and thus less side-effects.
Colon Cancer: Receptors, Signalling And Therapeutics

Summary
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. During this research program, we will explore these systems further, concentrating on the identification of novel inhibitors of colon cancer cell gr ....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. 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

An X-ray Crystallographic Investigation Into The Adaptive Immune Response To Epstein Barr Virus
Funder
National Health and Medical Research Council
Funding Amount
$521,961.00
Summary
This proposal is focussed on understanding the precise shape of proteins that control the immune response to Epstein Barr Virus. EBV is an ubiquitous human pathogen that has been linked to a number of cancers. This research proposal will further our understanding of the immune response to EBV, which will lay the foundations for developing therapeutics against this disease.
Affinity-based Profiling Of Bacterial Fe(III)-siderophore Receptors: Design Strategies For Antibiotics And Iron Overload
Funder
National Health and Medical Research Council
Funding Amount
$275,016.00
Summary
In order to establish an infection, bacteria compete with the host for iron, which is in scarce supply. To access iron, bacteria produce compounds called siderophores which bind iron strongly. The iron-siderophore complex, which is unique to each bacterium, is recognised by specific receptors at the bacterial cell-surface and imported for use. In this project, we are using modified siderophores as platforms for bacteria-specific drug design with the aim of producing new antibiotics.
