Dr Holly Barker is a Senior Research Fellow at WEHI, co-leading the WEHI-Stafford Fox Rare Cancer Program (WEHI-SFRCP), which has consented >950 individuals with rare cancers to enable molecular profiling and preclinical model development. She leads projects with a focus on aggressive uterine malignancies, spanning genomics, organoid and PDX model development, drug screening and clinical translation. Dr Barker’s Cancer Research paper established the biological basis for treating ovarian carcinosarcoma (OCS), an aggressive rare cancer with no approved therapies. Her team demonstrated that epithelial-to-mesenchymal transition (EMT) drives OCS tumorigenesis and confers sensitivity to eribulin, a microtubule inhibitor, using PDX models. This directly led to patient benefit in an area of profound unmet need, underpinning the EPOCH international clinical trial (she attracted >$7.5M in-kind drug support from Eisai & MSD), for which she is Translational Research Lead.
Prior to her involvement in the WEHI-SFRCP, Dr Barker spent eight years as a postdoc at the Institute of Cancer Research in London. Her research focused on the tumour microenvironment (TME) in breast and head and neck cancers. With respect to breast cancer, she focused on the role of the collagen cross-linker, LOXL2, in breast cancer cell invasion and metastasis and supported the development of LOXL2 inhibitors by Gilead Sciences. Dr Barker currently holds a Victorian Cancer Agency Mid-Career Research Fellowship to undertake multi-omic analysis of uterine serous carcinoma and perform drug screening to define combination therapies involving HER2- and PARP-targeting agents. She also holds a philanthropic uLMS grant expanding her previously uLMS work to spatial transcriptomics and organoid studies. Overall, her research projects cover topics, such as EMT, DNA damage repair, genomic instability, cell signalling, matrix biology and metastasis, and employ a range of techniques, including spatial transcriptomics, single-cell RNA sequencing, multiplex immunofluorescent imaging, cell surface proteomics, flow cytometry, drug screening, organoid development and 3D bioprinting.
