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.

Corneal and Ocular Surface Immunology and Regeneration
Assoc Professor Holly Chinnery’s career in ocular immunology began with a focus on animal models; however, it has recently transitioned into clinical imaging studies involving human research participants. The ability to visualise the immune system and sensory nerves in the human cornea represents a significant advantage in corneal immunology and neuroimmunology research.

Life-changing donor milk for preterm babies
Dr Laura Klein is National Milk Research Leader at Australian Red Cross Lifeblood. Australian Red Cross Lifeblood is funded by Australian governments to provide life-giving blood, plasma, and transplantation and biological products.
Dr Klein works with clinicians and researchers across Australia to understand how donated breast milk can be used to improve outcomes for vulnerable babies. She’s passionate about generating evidence to improve the products and services that milk banks provide to donors and the families who receive donated breast milk.
