Ovarian cancer, one of the deadliest cancers affecting women worldwide, is a challenging disease to treat. High rates of chemotherapy resistance hinder treatment success and patient survival.
Dr Alex Cole, from the Centenary Institute’s Centre for Biomedical AI, is now leading the research focused on developing a new treatment to counteract a protein called follistatin (FST), known for making ovarian cancer cells resistant to chemotherapy.
By employing cutting-edge molecular biology and directed evolution techniques, the project aims to create nanobodies—small, precise molecules—that can block FST. If successful, these nanobodies could enhance the effectiveness of chemotherapy and improve ovarian cancer treatment rates.
“We know that chemotherapy triggers increased FST production in the body, which aids cancer cells in resisting treatment,” said Dr Cole.
“Our nanobodies, derived from antibodies and engineered to target and neutralise FST, could potentially make cancer cells vulnerable to chemotherapy again.”
Dr Cole emphasised the critical importance of developing innovative therapies like FST nanobody therapy to improve patient outcomes.
“Chemotherapy is initially highly effective in treating ovarian cancer in women. However, in over 70% of cases the cancer will reoccur, often having developed resistance to chemotherapy, rendering it ineffective,” he said.
The grant, received through Cancer Australia’s Priority-driven Collaborative Cancer Research Scheme (PdCCRS) is co-funded by Cancer Australia and the Ovarian Cancer Research Foundation
Dr Cole received his PhD from the University of Sydney in 2017 (Kolling Institute) where he studied the role of epigenetic histone modifications on ovarian cancer. Alex continued his ovarian cancer research investigating the role of quiescence on cancer stem cells during Postdocs at the University of Michigan and the University of Pittsburgh. During this time, he received the Ann and Sol Schreiber Mentored Investigator Award from the Ovarian Cancer Research Fund Alliance, which led to the discovery that follistatin is secreted in response to chemotherapy where it actively promotes chemoresistance.
In 2020, he joined the Directed Evolution Lab at the Centenary Institute under Associate Professor Daniel Hesselson, where he worked to develop the novel viral directed evolution platform PROTEUS (Protein Evolution Using Selection). In 2023, Alex received a Tour de Cure grant which allowed for the validation of PROTEUS for nanobody evolution.

Biomarkers for early sepsis detection
Dr Gabrielle Briggs is a biomedical scientist dedicated to finding smarter, faster ways to diagnose and treat life threatening complications in critically ill patients. Dr Briggs established a research laboratory embedded within the John Hunter Hospital – one of the busiest major trauma centres in NSW. Dr Briggs works alongside surgeons, intensivists, and pathologists to turn complex clinical problems into practical research solutions. Her work spans two major programs: developing a rapid diagnostic test to detect bacterial infections in blood before sepsis takes hold, and exploring mitochondrial transplantation as a novel therapy to rescue injured tissues after trauma and ischaemia.

Brain ageing, dementia and psychiatric disorders
Professor Perminder Sachdev graduated from the All-India Institute of Medical Sciences, New Delhi, in 1978 and completed his MD in Psychiatry there in 1983. Following time in New Zealand, he relocated to Australia, where he completed psychiatric training and a PhD at UNSW in 1991. His doctoral work examined ethnopsychological concepts in Māori culture. His early research focused on drug-induced movement disorders, including akathisia, tardive dyskinesia and neuroleptic malignant syndrome, while his later work has centred on dementia and pre-dementia syndromes, particularly neuroimaging, biomarkers and risk factors.

Causal genes and pathogenic mechanisms underlying gastrointestinal diseases
Professor D’Amato has more than 25 years research experience in the field of human genetics and complex diseases, with activities most recently geared towards a translational application for therapeutic precision in gastroenterology. His team, the Gastrointestinal Genetics Laboratory, combine leading expertise in genomic, computational and pre-clinical research, and have contributed important breakthroughs linking specific genes and pathogenetic mechanisms to a number of gastrointestinal diseases like inflammatory bowel disease (IBD), microscopic colitis (MC) and irritable bowel syndrome (IBS).
