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.

Determing Whether Breast Stem Cells Mediate The Risk Of Developing Breast Cancer
Funder

Funding Amount
$433,894.00
Summary
Whilst the outcomes for women with breast cancer have improved significantly, the incidence of breast cancer continues to increase. Research needs to focus on prevention now to try to stop the increase. Apart from age, our reproductive behaviour is the largest risk factor for breast cancer. If a woman does not bear children, or has them after 35 years of age, she is at 25-50% increased risk of breast cancer. We would like to determine whether the breast stem cells play a role in this and why.
The Characterisation Of An Essential Regulator Of Pre-mRNA Splicing Required For Germ Cell Function And Male Fertility
Funder

Funding Amount
$1,116,739.00
Summary
The male germ line is a fantastic system within which to define processes of fundamental importance to cell biology and health broadly. Within this grant we will define the role of a poorly described RNA splicing factor in all of stem cell function (spermatogonia), meiosis (spermatocytes) and in the remarkable metamorphosis underlying spermatid maturation. This will be done using a range of phenotypic characterizations, CHIP and RNA Seq technologies and gene sequencing.
Katanin P80 Is A Key Regulator Of Microtubule Dynamics And Male Fertility.

Funding Amount
$603,756.00
Summary
Male fertility is a complex process requiring the co-ordinated activation of thousands of gene products. It is not surprising therefore that 1 in 15 Australian men are infertile. This project will explore an essential pathways for sperm production, specifically related to sperm shaping and motility. This work may ultimately have implications for the diagnosis and treatment of male infertility, but also for pathology in tissues will similar cellular structures.
Epigenetic Regulation Of Male Fetal Germ Cell Development.

Funding Amount
$562,176.00
Summary
Men’s health has declined over recent decades, but the causes remain unknown. Non-genetic (epigenetic) mechanisms affecting formation and function of the male germ cells (which produce sperm) may play an important role. We will determine the role of a key epigenetic modifier on the formation and function of male germ cells, including germ cell tumours. This study will provide fundamental insights into male germ cell epigenetics, and significantly contribute to understanding men's health.
Antioxidant Enzymes Counter Reactive Oxygen Species From Steroidogenic Cytochrome P450 Enzymes In The Ovary To Limit Aneuploidy Of Embryos

Funding Amount
$536,978.00
Summary
Many birth defects are due to damage sustained by the eggs before ovulation. Aging allows more damage, hence the advice to have babies earlier in life. However, we believe we have identified a source of damage that happens during late development of the follicle in the weeks before ovulation. Proving this will enable us define when an egg is most at risk of damage and to devise strategies to lower the risk.
Manipulating Ovarian Follicle - Oocyte Communication To Control Reproductive Outcomes
Funder

Funding Amount
$567,424.00
Summary
Ovarian follicles provide the environment supporting oocyte (egg) development. Communication between cells of the follicle and oocytes modulate this environment. We discovered new cell surface molecules that receive the signals from the oocyte and we identified a class of drug compounds that can modulate this signalling. This discovery offers a unique potential to therapeutically intervene in this signalling process and both improve infertility therapies and develop new non-steroidal contracepti ....Ovarian follicles provide the environment supporting oocyte (egg) development.

Male-female Sperm Signalling - A Novel Pathway For Peri-conceptual Health?
Funder
National Health and Medical Research Council
Funding Amount
$674,920.00
Summary
This project will investigate a new biological process in reproduction, whereby sperm delivered to the cervix at coitus transmit signalling molecules called microRNAs that influence the female immune response, to increase the chances of conception and pregnancy. We will define the molecular details of this signalling pathway in mouse models, and then determine whether human sperm have a comparable function in ‘priming’ the female body to conceive.
