Just published in Cancer Reports is our new protocol paper detailing the development of a rapid high-throughput (96wp) 3D organotypic coculture assay that is optimised for screening cancer cell and cancer-associated fibroblast response to drugs in physiologically relevant matrices.

We have just published a new paper in Breast Cancer Research in collaboration with lead researcher Dr. David Croucher from the Garvan Institute, looking at how and why ERBB2 (HER2) positive breast cancer cells develop resistance to targeted therapies such as trastuzumab (Herceptin™).

Our latest review in collaboration with Dr. David Croucher and Dr. Dirk Fey on ‘The extracellular matrix as a key regulator of intracellular signalling networks‘ has just been published as part of a special series on ‘Translating the Matrix’ in the British Journal of Pharmacology.
Computational model of the interplay between the ECM and drug activated MAPK‐JNK signalling network.
At their simplest, cells follow a set of rules governed by their genetic code. These rules, which are executed by the protein‐based signalling networks that the genes encode, control the assimilation of information and decision‐making processes that shape a cell’s response to their surroundings.

The Matrix and Metastasis group is excited to be welcoming two new Honours students to the team for 2019.
Yordanos Setargew (left) and Shivanjali Ratnaseelan (right) will both be joining us to spend the next 10 months in the lab as part of their UNSW Sydney, School of Medical Sciences (SoMS) Honours Program.

Yordanos will be looking at new ways to target the lysyl oxidase (LOX) family in pancreatic cancer, and Shivanjali will be looking at how the biomechanical properties of the tumour microenvironment alter breast cancer cell sensitivity to chemotherapy.

Just published in Molecular Biology of the Cell is our recent paper looking at the effect of extracellular matrix stiffness on the intrinsic biomechanical properties of cancer cells. Led by Professors Janine Erler (Biotech Research & Innovation Centre) and Lene Oddershede (Niels Bohr Institute) both from the University of Copenhagen, the study combines optical tweezers–based microrheology and deformability cytometry with 3D biological models to dissect how cancer cells biomechanically interact with and respond to the stiffness of the microenvironment they are within.

The results show that invasive cancer cells adjust their intracellular and overall viscoelasticity to ECM density, and that cancer cell viscosity increases during invasion into 3D collagen matrices.

The lab is excited to be welcoming our first Ph.D. student Michael Papanicoloau who has just started in the lab. Michael joins us after completing his Honours degree in Biomedical Science at UTS and the Woolcock Institute of Medical Research.
Having been awarded a prestigious UTS Research Excellence Scholarship, Michael’s Ph.D. will focus on understanding how the extracellular matrix changes over time in solid tumours, in particular breast cancer, and how these changes feed into the pathological progression of the disease at both primary and secondary sites.

Our new paper has just been published in Oncotarget. In this study, we show that Tumor endothelial marker 8 (TEM8) regulates the expression of multiple genes. In particular, we observed that the most common expression changes conserved between breast and colorectal cancer are involved in regulation of the cell cycle. In line with the microarray results we show that TEM8 regulates cancer cell proliferation and primary tumor growth. Since TEM8 KO tumors presented with fewer blood vessels we hypothesize that TEM8 contributes to the regulation of angiogenesis, likely by being secreted by cancer cells to alter endothelial cell migration and thereby supporting growth of the tumor. Moreover, we confirm that TEM8 is an important player in driving tumor cell invasion and metastatic dissemination in breast cancer.
Proposed mechanism behind the impact of TEM8 on breast and CRC cancer progression.
