CASE STUDY
Filmed in Melbourne | March 2025
A landmark study led by WEHI and La Trobe University has found a potential new diagnostic marker that could be used to better detect the level of tissue damage in our bodies.
This study revealed, for the first time, a link between levels of EVs in the blood and tissue damage caused by diseases such as leukaemia.
Researchers hope to leverage the critical new insight to develop a blood test to monitor cancer patients with tissue damage, which could, in future, enhance treatment strategies for blood cancers and other diseases.
Extracellular vesicles (EVs) are like small delivery trucks in the human body that are dispatched by our cells to distribute important materials like proteins, fats and genetic information to other cells.
This delivery system helps cells communicate with each other, especially when they are under stress or dying.
Research into how EVs form and their link to disease progression is challenging because of their small size, with most studies restricted to a ‘cells-in-a-dish’ approach.
In an unprecedented study, researchers were able to overcome this significant barrier by imaging live EVs inside the bone marrow of mice.
The study involved a significant collaboration with Professor Ivan Poon, Director of the La Trobe Research Centre for Extracellular Vesicles (RCEV) – the largest group of EV researchers in the Southern Hemisphere.
The WEHI research team is now assessing whether EVs can be used as a biomarker in acute myeloid leukemia (AML) patients. They hope to develop new tools and techniques that would allow clinicians to determine the impact of disease on healthy tissue, and assess the disease progression by analysing patient samples.
The study, published in Nature Communications Oct 2024, also involved collaborations with the University of Melbourne, The Florey, Olivia Newton-John Cancer Research Institute, Peter MacCallum Cancer Centre and Monash University.
The research was supported by the National Health and Medical Research Council, Australian Research Council, CASS Foundation, Jack Brockhoff Foundation, L’Oreal UNESCO For Women in Science, Victorian Cancer Agency, a Sir Clive McPherson Family Fellowship and a Rae Foundation grant.

Benefits of prehabilitation ahead of surgery
Dr Matthew Wallen PhD, AES, AEP is a Senior Research Fellow in Cancer Survivorship, the Deputy Lead of the Cancer Survivorship Program, and a Senior Lecturer in Exercise Science and Clinical Exercise Physiology within the College of Nursing and Health Sciences at Flinders University, in South Australia. His clinical interest focuses on improving outcomes for people requiring major surgery, specifically (1) lifestyle interventions, including exercise, nutritional, and psychological support to improve the health and wellbeing of people prior to surgery, termed ‘prehabilitation’, (2) novel physical function assessments aimed at identifying people at risk of treatment-related complications, and (3) implementation of new models of care in cancer.

Better biomarkers for predicting the incidence of having atherosclerosis and heart attack
Assoc Prof Bursill is a vascular biologist with interests and expertise in vascular inflammation, atherosclerosis and angiogenesis. She completed her PhD at The University of Adelaide in lipid metabolism then headed to Oxford University for five years to undergo a postdoctoral post in the Departments of Cardiovascular Medicine and Pathology. Her postdoctoral time triggered her interest in the mechanisms that cause atherosclerosis and in particular the role of small inflammatory proteins called chemokines.

CASE STUDY Role of Exercise in Metabolic Associated Fatty Liver Disease
Dr. Shelley Keating AES AEP* is an Accredited Exercise Physiologist, a researcher, and a senior lecturer at the School of Human Movement and Nutrition Sciences at the University of Queensland in Brisbane, Australia. Dr. Keating’s research primarily focuses on the role of exercise in the management of metabolic dysfunction associated steatotic liver disease (MASLD), previously known as non-alcoholic fatty liver disease. MASLD affects a significant portion of the global adult population, with many individuals unaware of their condition.
