Publication: Tumor endothelial marker 8 promotes cancer progression and metastasis

Thomas R. Cox, Jul 2018

Tumor endothelial marker 8 promotes cancer progression and metastasis

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.

Understanding how molecules and cells behave in living animals can give researchers key insights into what goes wrong in diseases such as cancer, and how well potential treatments for these diseases work. Continue reading

Publication: Charting the unexplored extracellular matrix in cancer

Charting the unexplored extracellular matrix in cancer

Our new review on the recent advances in mapping the extracellular matrix in cancer has just been published in the International Journal of Experimental Pathology.

Composed of hundreds of different building blocks, the extracellular matrix (ECM) makes up the complex, highly cross‐linked, three‐dimensional (3D) network of macromolecules (proteins, glycoproteins and its subgroup of proteoglycans, polysaccharides (glycosaminoglycans), elastins and carbohydrates) that surround cells. It is essential to correct organisation and function of all tissues and organs, yet we know remarkably little about the assembly and organisation of these supramolecular structures of the ECM. In this review we discuss some of the recent advances and technologies that are helping us delve deeper into the matrix and further our understanding of the impact that dysregulated ECM has in diseases such as cancer.

Publication: Three-dimensional organotypic matrices from alternative collagen sources as pre-clinical models for cell biology

Three-dimensional organotypic matrices from alternative collagen sources as pre-clinical models for cell biology

Our new paper on alternative collagen sources for 3D organotypic cultures for use as pre-clinical models is now out in Scientific Reports

Collaroo: 3D Organotypic matrices for cancer biology

Cellular interactions with the extracellular matrix (ECM) occur in a three-dimensional (3D) context and this essential aspect of the tumour microenvironment can lead to altered sensitivity to therapeutics and even act as a barrier to their delivery. This key feature is often overlooked in pre-clinical studies and is likely one of the central factors contributing to the high attrition rates of lead compounds within the pharmaceutical industry. This organotypic platform allows assessment of lead compounds in both the stromal compartment or in a 3D co-culture setting using large scale collagen preparations from alternative sources.

Matrix: Dissolved – ABC Radio Network Health Report

ABC Radio National LogoThomas R. Cox, July 2017

I was recently invited to chat with Norman Swan on ABC Radio National’s Health report about some of the recent work we have been doing on the Extracellular Matrix in cancer.

The extracellular matrix or the matrix is the web- or mesh-like structure that encases the cells in the tissues and organs of our body.

We recently developed a new technique which dissolves the cells from tumours to leave behind this matrix, allowing us to study it in unprecedented detail – and we discuss the potential of these research outcomes. Continue reading

“We’re seeing things we’ve never seen before”: groundbreaking new technique sheds light on the ‘matrix’ surrounding our cells

Our most recent research  has just been published in Nature Medicine.

In our  paper we describe a new and intuitive new way to dissolve cells from tissues, leaving behind the extracellular matrix (ECM) or ‘matrix’.

The matrix is made up of 100’s of differing building blocks and surrounds the cells in our body. It is incredibly important in the progression and spread of cancer – but up until now it has been notoriously difficult to study in detail.

Publication: Transient tissue priming via ROCK inhibition uncouples pancreatic cancer progression, sensitivity to chemotherapy, and metastasis

Thomas R. Cox, Apr 2017

ROCK-ing pancreatic cancer to the core

Our new paper on short-term pulsed treatment, or ‘priming’ as a treatment strategy to boost chemotherapy has just been published in Science Translational Medicine.

Transient tissue priming via ROCK inhibition uncouples pancreatic cancer progression, sensitivity to chemotherapy, and metastasis

The research, spearheaded by Dr. Paul Timpson and Dr. Marina Pajic here at the Garvan Institute of Medical Research in Sydney, has uncovered a promising new approach to treating pancreatic cancer. By targeting the tissue surrounding the tumour to make it ‘softer’, it leads to tumours being more responsive to chemotherapy.

Pre-metastatic niches: organ-specific homes for metastases

Our new review on the importance of the pre-metastatic niche (PMN) in cancer has just been published in Nature Reviews Cancer. It summarises the natural progression of pre-metastatic niche formation and evolution, highlighting recent advances and future hurdles.
