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.

Cytoskeletal Regulation Of Adhesion Structure And Cell Movement

Funding Amount
$60,420.00
Summary
Metastatic (secondary) cancers are a frequent cause of patient mortality. Central to the development of metastasis is cell motility-movement. A key component of cell movement is the way that cells bind and release the extra-cellular matrix as they move. By understanding how the dynamics of cell interaction with the matrix are regulated, we will identify molecules that are critical to the development of metastatic cancer and thus novel targets for inhibition of metastasis.
Most normal cells naturally cease their growth because their chromosomes erode from repeated cell division. The erosion takes place at the ends of the chromosomes, or telomeres. All cancer cells avoid this erosion, and thus fail to cease their growth. About 85% of all cancers achieve this by activating an enzyme called telomerase, an enzyme that allows cancer cells to avoid the natural ageing process. This project aims to understand how this enzyme gets recruited to chromosome ends.
Generation Of Embryonic Stem Cell-like Cells By Reprogramming Somatic Cell Nuclei

Funding Amount

Summary
Human embryonic stem (ES) cells possess considerable potential in treating numerous human diseases. However, ethical concerns surround the isolation of embryonic stem cells from human embryos. Therefore, this proposal aims to develop a reliable method of deriving human ES-like cells from normal adult cells (eg. skin cells). For example, preliminary results suggest ES cells can impart their 'stemness' onto adult cells when the two cells are fused together.
Clinical And Molecular Analyses Of Nodular Melanoma

Summary
There have been very recent advances in our understanding of the biology of melanoma that are now poised to have major impacts in the outcome of patients with this disease. The nodular subtype of melanoma contributes disproportionately to mortality from melanoma. By using the latest molecular techniques to study these melanomas I will identify causative factors, diagnostic features and molecular profiles associated with these poor-prognosis melanomas leading to new approaches in the prevention, ....There have been very recent advances in our understanding of the biology of melanoma that are now poised to have major impacts in the outcome of patients with this disease.

Identification Of Genes That Predict Outcomes In Acute Leukaemia

Summary
This study aims to identify genetic factors that contribute to the resistance of acute leukaemias to treatment, and to poor outcomes in patients with acute leukaemias.
The Characterisation Of The Mechanism Of Beta Amyloid Toxicity In Alzheimer's Disease
Funder
National Health and Medical Research Council
Funding Amount
$94,430.00
Summary
Alzheimer�s disease (AD) is the most common form of dementia and is characterised by the beta amyloid peptide (A_) found in plaques in the brain. A structural transition to aggregated/ oligomeric forms of A_ is accompanied by a gain of toxicity. In this study the biological and biophysical characterisation of a variety of A_ peptides will be performed. The study will also use oligomers from cell culture media and brain tissue that have been influential in AD research but poorly characterised.
Biological And Clinical Characterisation Of Human Phosphatidylinositide 3-kinase Mutations
Funder
National Health and Medical Research Council
Funding Amount
$33,626.00
Summary
The frequency of PI3K mutations in tumours, suggests that PI3K is one of the most common human oncogenes. Understanding the biological and biochemical significance of these mutations will provide new insights into the biology of human tumourigenesis and further our understanding of the consequence pathways and the progression of human tumours. Such knowledge will help us to identify more effective markers of prognosis, diagnosis, early detection of cancer and design new anti-cancer therapy.
