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.

Interaction Of Mc1r With The PRb And P53 Pathways In UVR-induced Melanoma Development
Funder
National Health and Medical Research Council
Funding Amount
$553,479.00
Summary
This project will shed light onto fundamental processes causing UV-induced melanoma (MM). Innate differences between individuals, independent of pigmentation, influence MM development. We will study the mechanisms of UVR-induced MM development in mice carrying gene mutations (Cdk4, Arf, Mc1r) that underpin human MM susceptibility. Knowledge of the sensitivity of an one's MCs to UV could be critical for targeting susceptible groups for health education campaigns and more intense screening.
Defining The Genetic Requirements For Maintenance Of Colorectal Cancer
Funder
National Health and Medical Research Council
Summary
Colorectal cancer is the second leading cause of cancer-related death worldwide because there are few effective treatments for people with aggressive disease. The goal of this project is to uncover how normal colon cells suppress cancerous changes and to identify the important factors that colon cancer cells depend on for survival and growth. With this knowledge we can begin to develop more effective cancer treatments with fewer side-effects.
The Genetic Control Of Platelet Production And Function

Summary
Platelets are the tiny cells that circulate in the body and make blood clot. The human body has more than a trillion of them at any one time, and they are replaced every week by the blood producing cells that reside in the bone marrow. Keeping the normal number of platelets steady is incredibly important any significant drop can result in a life-threatening hemorrhage. The clinical name given to a low platelet count is thrombocytopenia, and it is a very common problem.

The human body has more than a trillion of them at any one time, and they are replaced every week by the blood producing cells that reside in the bone marrow. Keeping the normal number of platelets steady is incredibly important any significant drop can result in a life-threatening hemorrhage. The clinical name given to a low platelet count is thrombocytopenia, and it is a very common problem. It can be caused by genetic mutations, viral infections, or by cancer treatments like chemotherapy. The only way to raise platelet numbers in a person with thrombocytopenia is a blood transfusion, which carries with it risks and potential side effects. While we understand quite a lot about how the body produces platelets, we don t know anywhere enough to be able to develop new treatments. Our work is focused on the identification of the genes that control the process, beginning with mouse models of thrombocytopenia, genome mapping, gene isolation, and finally, making the links between the newly identified genes and patients with thrombocytopenia. It will give us a much better understanding of how platelets are produced, how things go wrong in human disease, and how new therapies might be developed to treat them.Read moreRead less
The Role Of Muscle And The Application Of Muscle-cell Therapies In Bone Repair
Funder
National Health and Medical Research Council
Funding Amount
$438,936.00
Summary
Muscle is often close to bone and we have found that muscle cells can directly contribute to bone repair. We are examining importance of muscle cells in orthopaedic repair and whether new methods for mobilizing muscle cells can improve healing.
Manipulating Cardiac-selective PI3K Targets To Reverse Heart Failure Progression
Funder
National Health and Medical Research Council
Funding Amount
$532,921.00
Summary
Heart failure is a major clinical problem which is becoming worse as our population ages. New therapeutic strategies with the capability of improving function of the failing heart are greatly needed. We have identified novel targets of a gene with protective properties in the heart. This proposal will examine whether these new targets can reverse heart failure progression. Technologies that target these genes may lead to innovative pharmacotherapies in the clinical management of heart failure.
Site-specific Integration Of Functional Genomic Loci: Applications In Gene Therapy
Funder
National Health and Medical Research Council
Funding Amount
$442,664.00
Summary
Gene therapy strategies have traditionally focused on the delivery of therapeutic genes by viral vectors. Mindful of the limitations and potential problems of viral gene delivery, non-specific viral integration and limited transgene expression, this investigation will explore the delivery and site-specific integration of large genomic fragments into human stem cells. It is anticipated this approach will avoid some of the problems associated with poor gene expression and insertional oncogenesis.
Deregulated Cytokine Signalling As A Molecular Bridge Linking The Pathogenesis Of Emphysema To Lung Cancer.
Funder
National Health and Medical Research Council
Funding Amount
$524,820.00
Summary
Lung cancer is the most lethal form of cancer in Australia and worldwide. Although smokers with emphysema are at an increased risk of developing lung cancer, it is becoming apparent that emphysema can predispose to lung cancer independently of cigarette smoking, albeit by unknown mechanisms. Our aim is to combine smoke carcinogen and genetic mouse models of lung cancer with novel mouse strains displaying emphysema to identify the processes which link the pathogenesis of emphysema to lung cancer.
Intraprostatic Androgen Signalling As A Target In Prostate Cancer
Funder
National Health and Medical Research Council
Funding Amount
$372,049.00
Summary
Male hormones (androgens) are the fuel that drives prostate cancer so reducing androgen levels is the standard treatment but cant cure the disease and causes serious side-effects throughout the body. We need to better target androgen withdrawal to prostate cancers and learn more about how it works to improve treatment. This project utilizes unique mouse models for experiments not feasible in humans to learn how androgens act and can be better targeted to cure prostate cancers.

The project is divided into three parts. In the first part of the project, the research team will identify further novel disease genes, some of which they are already close to finding. In the second part of the project the team will determine how the mutations they have identified in the disease genes actually cause the diseases. The aim of this work is to discover targets that may ultimately lead to new therapies for these muscle diseases. In the third and final part of the project, the team will pursue one possible therapeutic approach, which is based upon the understanding of the diseases the researchers have gained from their previous studies. There are currently no cures for these muscle diseases, though symptoms can be treated. The team will determine whether heart actin can replace muscle actin in skeletal muscle and thus might treat the muscle disease.Read moreRead less
