Alterations in the extracellular matrix at the biochemical, biomechanical, architectural and topographilcal levels contribute to the development and progression of solid tumours. Our increased understanding of matrix biology is leading to the development of new approaches that co-target the matrix in cancer, including in metastasis.
Targeting Lysyl Oxidase Family Meditated Matrix Cross-Linking as an Anti-Stromal Therapy in Solid Tumours
Congratulations to Kaitlin and Yordanos who just had their co-first author review published inCancers as part of a special edition on Treating the Cancer Matrix: Progress in the Identification of Potential Therapeutic Targets. Also a shout out to Rhiannon for her amazing illustrator skills and creating some beautiful figures. And finally to Jess, who as co-senior author played an instrumental role in bringing everything together.
Remodeling of the extracellular matrix (ECM) in solid tumours. In healthy tissue, the ECM has a structured basement membrane consisting primarily of collagens IV and VI as well as a scaffolding arrangement of fibrillar collagens that are predominantly secreted by the fibroblasts. In comparison, solid tumours typically consist of more densely packed, aberrantly cross-linked fibrillar collagens resulting from the recruitment and activation of CAFs. As the level of deposition of fibrillar collagens such as collagens I, III and V increases in the tumour ECM, so too does LOX family mediated collagen cross-linking. In addition, tumour ECM results in a breakdown of the structure of the normal basement membrane.Continue reading →
The Role of the ECM in Lung Cancer Dormancy and Outgrowth
We are pleased to report that our recent in depth review on the role of the extracellular matrix (ECM) in Lung cancer, both in primary and metastatic settings has just been published as part of a special edition on ‘Revisiting Seed and Soil: A New Approach to Target Hibernating Dormant Tumor Cells‘ in Frontiers in Oncology: Molecular and Cellular Oncology.
Stromal cell diversity associated with immune evasion in human triple‐negative breast cancer
We are excited to have been part of a recent piece of work using single cell genomics to map the different cell types present with triple negative breast cancer which has recently been published in EMBO.
The work, led by Alex Swarbrick and his team here at the Garvan uncovered four new subtypes of cells within triple negative breast cancer, which contain promising new therapeutic targets for the aggressive disease. These cells produces molecules that suppress immune cells, which may help cancer cells evade the body’s immune system, and the work could lead to a new class of therapies for triple negative breast cancer.
Plasma polymerized nanoparticles effectively deliver dual siRNA and drug therapy in vivo
We are delighted to have been part of an exciting study looking into the potential of a new class of multifunctional nanocarrier to deliver dual siRNA and drug therapy to breast tumours which was recently published in Scientific Reports.
The work was led by our collaborators Miguel Santos and Steven Wise from the Applied Materials Group at the University of Sydney who pioneered the development of these novel multifunctional nanocarriers.
Australian Pancreatic Cancer Matrix Atlas (APMA) as a national and international portal for pancreatic cancer and matrix biology research
We are delighted to announce the launch of our Avner Australian Pancreatic Cancer Matrix Atlas (APMA) as a national and international portal for pancreatic cancer and matrix biology research.
About APMA
Desmoplasia (fibrosis) is a key hallmark of pancreatic cancer, which can be targeted in concert with tumour cell-centric therapies. The overarching goal of APMA is to facilitate the translation of stromal-centric therapy as a mainstay in our emerging multimodal armoury against pancreatic cancer.
APMA is a collaborative effort by researchers at the Garvan Institute of Medical Research and The Kinghorn Cancer Centre in Sydney, working closely with clinical teams at Royal North Shore Hospital.
Committee Members
Prof. Paul Timpson, A/Prof. Thomas Cox, A/Prof. Marina Pajic, Prof. Anthony Gill, Dr. Brooke Pereira, Dr. David Herrmann, Prof. Jas Samra, Amber Johns, Gloria Jeong.
Vision and goals
APMA’s aim is to better understand how the dynamic extracellular matrix landscape is linked to alterations in drug response and patient survival in pancreatic cancer. By mapping the histological, immunohistochemical, and proteomic differences between normal pancreatic tissue and matched pancreatic cancer samples we aim to define which matrix elements are deregulated in this disease and reveal new targets.
Detailed comprehensive mapping of the topology and 3D structure of the matrix in native pancreatic tissue and pancreatic cancer, in correlation with clinicopathological and genetic sequencing data, has not been possible until now. The Garvan Institute of Medical Research, working with the Royal North Shore Hospital (RNSH) here in Australia are perfectly placed to achieve this, thereby establishing the first national and international comprehensive human pancreatic cancer matrix database.
APMA is positioned to become an international resource held in Australia for pancreatic cancer matrix targeting, creating a portal for matrix biology researchers and clinicians to interrogate and query disease progression, outcome, survival and relapse in the context of matrix composition and 3D matrix topology. APMA integrates our laboratory based studies of the matrix with clinicopathological data including survival, relapse, and resistance, to identify matrix companion biomarkers and actionable targets that may be diagnostic and/or prognostic.
We are delighted that Yordanos Setargew who recently graduated with First Class Honours from our the lab will be continuing on in the team as one of our Research Assistants.
Yordanos will continue working on projects focussing on the role of the extracellular matrix in pancreatic cancer.
As with any new lab (M&M turned 3 a couple of months ago 🎉), the first few years are typically about building a reliable team to help a new PI lay the foundations for establishing a functioning (and hopefully successful) research laboratory. The actual hiring process is incredibly stressful for new PI’s, often agonising for days over their first few hires. A bad hire when starting out can really set you back when the lab is in a fledgling state. At the same time, the inevitable moving on of good hires can be equally as hard…
Cancer Metastasis: The Role of the Extracellular Matrix and the Heparan Sulfate Proteoglycan Perlecan
