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.

The Assessment And Treatment Of Cardiovascular Risk Factors,diabetes And Insulin Resistance In Polycystic Ovary Syndrome

Summary
Cardiovascular disease (CVD) and Type II Diabetes Mellitus (T2DM) are major health burdens in Australia. T2DM is increased and CVD may be increased in polycystic ovary syndrome (PCOS), a condition present in 10% of women and 30% of obese reproductive aged women. We aim to explore risk factors for CVD and T2DM in women with PCOS and to assess the effect of treatment strategies on metabolic and reproductive features in PCOS. This is crucial for reducing disease risk in this common condition.
Adrenal Cushings:natural History And Genetic Analysis Of Inherited Forms, And Prevalence In High Risk Groups.

Summary
This study aims to diagnose early Cushing's in certain high risk groups - before debilitating complications have developed which increase mortality. Early treatment normalises life expectancy and improves quality of life. We aim to discover the genetic cause of inherited Cushing's. This will allow a genetic test to be developed - so gene carriers can be carefully followed for onset of symptoms of Cushing's and those who are not carriers can be reassured.
Hormonal Influences In The Pathogenesis Of Ovarian Tumours

Summary
Ovarian cancer is one of the most common malignancies affecting the female reproductive system. We have found that two types of tumour of the ovary produce a hormone called inhibin; these tumours are also known to produce the steroid hormone estrogen. In these studies we are seeking to determine the genetic changes in the tumours that cause the production of these hormones. We suspect that these genetic changes are also the same changes which contribute to the development of the cancers.

We have found that two types of tumour of the ovary produce a hormone called inhibin; these tumours are also known to produce the steroid hormone estrogen. In these studies we are seeking to determine the genetic changes in the tumours that cause the production of these hormones. We suspect that these genetic changes are also the same changes which contribute to the development of the cancers. In order to identify these genes we will draw on our knowledge of the genes that are important in the controlof growth and hormone secretion in normal ovarian cells. To assist this molecular analysis we will use two ovarian cell lines in culture that have many of the features of the primary tumours including inhibin secretion. We will also use new techniques to scan over 500 genes involved in tumours in general to see whether we detect any unusual or distinctive patterns in this sub-group of tumours. A genome wide scanning technique will be used to seek changes in the DNA of the tumours, inparticular loss of genetic material or amplification of regions. Identification of the genetic changes within these tumours should enable better systems of classification, enhance prognostication and provide specific targets for the development of appropriate treatment strategies.Read moreRead less
Kallikrein Proteases Have Key Functional Roles In Peritoneal Invasion And Chemoresistance In Epithelial Ovarian Cancer
Funder

Funding Amount
$815,541.00
Summary
Only 30% of ovarian cancer patients with advanced disease survive for 5 years. This is because the cancer quickly spreads into the abdominal cavity and often becomes resistant to chemotherapy. We aim to use a new 3D culture system, mouse models and novel inhibitors to study the roles of 4 kallikrein enzymes in these events. The outcomes from this study will lead to a better understanding of the role of kallikreins in ovarian cancer and may lead to new treatment approaches.
Short Term Effects Of Overfeeding On Metabolic Risk In Humans

Funding Amount
$380,558.00
Summary
Obesity is associated with increased risk of diabetes, heart disease and cancer. Obesity prevalence is rapidly increasing and consitutes one of the greatest threats to human health. The aim of this study is to determine mechanism-s underlying the close relationship between obesity and insulin resistance by inducing experimental weight gain in humans with and without a genetic predisposition to diabetes. This project will help identify new candidates for anti-diabetes drugs.
Molecular Characterisation Of Adiponectin Receptors: Implications For Adiponectin Action And Resistance
Funder
National Health and Medical Research Council
Funding Amount
$95,137.00
Summary
Adiponectin is a hormone secreted by fat cells with anti-inflammatory, anti-atherogenic and insulin sensitising properties. Adiponectin levels and actions are compromised in obesity and type 2 diabetes. Adponectin mediates its effects via two receptors but the mechanisms are poorly understood. This proposal aims to define the underlying mechanisms with the ultimate goal of identifying novel therapeutic strategies to improve adiponectin's actions.
Evaluation Of The Therapeutic Potential Of SFTI-FCQR, A Novel Kallikrein 4-specific Protease Inhibitor

Summary
Prostate and ovarian cancers are on the rise in Australia's ageing population. In previous work, we have studied prostate and ovarian cancer cells that we have engineered to make the protease KLK4. These cells show signs associated with aggressive tumours and in particular may have some of the changes found in cancer cells that spread from their site of origin (metastasize). In this project, we will look at a drug-like molecule that we have designed with the aim of blocking the activity of KLK4.
