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.

Nocturnin: A Post-transcriptional Regulator Of Circadian Fat Metabolism
Funder
National Health and Medical Research Council
Funding Amount
$574,696.00
Summary
Our metabolism is aligned with the 24-hour rotation of the earth in what is termed the circadian clock. Being misaligned to this clock explains jetlag and the poor health associated with shift-workers. For example, whether fat is utilised or stored depends on the time of day. This study aims to investigate the post-transcriptional mechanisms that underpin the rhythmic changes that occur throughout our bodies to ensure that our metabolism is matched to our environment.
MicroRNA Pathway Control Of Immune Cell Development
Funder
National Health and Medical Research Council
Funding Amount
$631,370.00
Summary
The immune system is comprised of many different cell types, each with a specialised function. Many are short-lived and must be continually replenished throughout life. Abnormalities in this process underlie many human diseases, including immunodeficiency, autoimmunity and cancer. My laboratory seeks to understand the molecular pathways that control development of immune cells and to identify the defects that lead to disease.
The 3’ UTR Codes That Control MRNA Translation In Development

Funding Amount
$609,281.00
Summary
We are the product of an exquisite programme that controls when and where genes are turned on and off, over time, from a single cell to adulthood. This project concerns codes that regulate this programme with a focus on early development, the germline and neuronal cells. Using the same technology that now allows individuals to sequence their own genome, we will study an aspect of this timing in model organisms having genetic lesions in specific pathways that relate also to human health and disea ....We are the product of an exquisite programme that controls when and where genes are turned on and off, over time, from a single cell to adulthood.

Role Of Sirtuins In The Regulation Of The Carcinogen Metabolising Arylamine N-acetyltransferases
Funder
National Health and Medical Research Council
Funding Amount
$327,324.00
Summary
This project will investigate critical biochemical pathways that regulate metabolic differences in normal and cancer cells. By understanding how these processes differ, novel approaches for detecting and managing cancer cell proliferation in humans may be achievable.
Antibiotic Tolerance And Small RNA Networks In Staphylococcus Aureus
Funder
National Health and Medical Research Council
Funding Amount
$521,559.00
Summary
Treatment of MRSA is restricted to last line antibiotics and treatment failure is associated with an intermediate tolerance to vancomycin. Regulatory molecules termed small RNA mediate responses to antibiotic challenge but their functions are poorly understood. This proposal will profile sRNA function to understand how they adapt S. aureus to antibiotic challenge. A molecular understanding of vancomycin-tolerance will inform development of diagnostics and treatment strategies.
Post-transcriptional Regulation Of Plasminogen Activator Inhibitor 2 Gene Expression
Funder
National Health and Medical Research Council
Funding Amount
$508,838.00
Summary
Plasminogen activator inhibitor type 2 (PAI-2) is a protease inhibitor that has intracellular and extracellular functions. The PAI-2 gene is highly regulated at the level of PAI-2 mRNA stability. We have identified regions within the PAI-2 transcript essential for this regulation and a number of novel proteins that engage these regions. This project is aimed at understanding how these and other proteins control PAI-2 expression at the mRNA level.
Alternative Splicing- A Regulatory Mechanism Determining Self-renewal And Pluripotency Of ES And IPS Cells
Funder
National Health and Medical Research Council
Funding Amount
$664,650.00
Summary
Stem cells hold great promise in cell replacement therapies and may provide models to study human diseases and to screen new pharmaceuticals. For successful future therapeutic applications, a deeper understanding of the molecular mechanisms governing the behavior of stem cells is crucial. In this proposal we will investigate the role of alternative splicing in the control of the fundamental properties of stem cells, and identify target RNAs and gene expression networks regulated by splicing fact ....Stem cells hold great promise in cell replacement therapies and may provide models to study human diseases and to screen new pharmaceuticals.

RNA Binding Protein Musashi: Role In Folliculogenesis And Oocyte Development
Funder
National Health and Medical Research Council
Funding Amount
$419,223.00
Summary
Women in Australian have opted for social and economic reasons to delay both marriage and childbirth. Both infertility and congenital abnormality is associated with advancing maternal age as the ovarian pool of oocytes declines in number and quality. In this project we aim to gain an understanding of the molecular mechanisms underpinning healthy oocyte development. Insights gained have the potential to alleviate miscarriage, infertility and congenital abnormalities in Australian families.
The Contribution Of Upstream Open Reading Frames To The Eukaryotic Proteome
Funder
National Health and Medical Research Council
Funding Amount
$197,911.00
Summary
This project will investigate the novel idea that genomes of complex organisms (including human) 'double-dip' with many genes containing information for more than one protein. It will also examine if these small supernumary proteins have cell regulatory functions. If proved, it would significantly alter current views on the information content of higher vertebrate genomes. An understanding of the roles of these novel protein sequences may result in the development of new drugs.
