In a research career spanning more than 20 years, Professor Sansom has published over 300 papers and made major contributions to understanding some of the key molecular drivers of epithelial cancer.
Professor Sansom received his PhD from the University of Edinburgh in 2001 before continuing his postdoctoral research using in vivo models of cancer at the University of Cardiff. In 2005, he established his own laboratory at the Cancer Research UK Beatson Institute in Glasgow. Since then, Professor Sansom has been instrumental in determining the molecular hallmarks of colorectal cancer. This has included defining the roles of the tumour suppressor protein APC and the WNT signalling pathway as well as the involvement of intestinal stem cells in tumourigenesis. His laboratory uses both in vivo and 3D in vitro models to recapitulate colorectal and pancreatic cancers to investigate the molecular mechanisms underpinning tumourigenesis and to identify novel drug targets.
Professor Sansom has also played an important leadership and management role at the CRUK Scotland Institute (formerly the Beatson Institute), particularly in ensuring its researchers are able to access the most sophisticated genetically engineered models of cancer. In 2011, he was appointed Deputy Director of the Institute and has been its Director since August 2017. Professor Sansom is also more broadly involved in driving cancer research strategy in Glasgow – up until April 2021, he was Director of the Institute of Cancer Sciences, University of Glasgow and currently is the Co-Director of the CRUK Scotland Centre, a joint initiative between Edinburgh and Glasgow, which aims to translate findings from the laboratory into the clinic for the benefit of cancer patients. In September 2021, Professor Sansom was appointed Director of the National Mouse Genetics Network, an investment of more than £20 million by the Medical Research Council to accelerate our understanding of human disease, including cancer, and improve diagnosis and treatments.

Dr Philip Dunne is a Reader in Molecular Pathology, in the Patrick G Johnston Centre for Cancer Research at Queen’s University Belfast. His translational research programme primarily focusses in the identification, mechanistic interrogation and therapeutic targeting of the biology (particularly tumour-immune-stromal interactions) underpinning disease relapse in early-stage colorectal cancer. If we are to maximise patient benefits from the extensive pre-clinical research focussed on CRC in the UK, we must ensure that treatments are delivered to the right patients with tumour types that are fully aligned to the pre-clinical models that have demonstrated the most benefit. The Dunne lab research programme has enabled the development of a number of novel resources to align biomarkers to patient data and the most appropriate model(s), which may help in improving the translation of mechanistic science into clinical trials.
We have seen a revolution in the development of cell- and animal-based models, coupled with rapid advances in the technologies being used for molecular, proteomic and histological profiling of tumour samples. The Dunne group utilises cross-disciplinary methodologies for biological discovery and identification of molecular signalling and/or phenotypes that will enable improved understanding of disease and translation of potential therapeutic options. The expertise required to perform, analyse and interpreted these new data now extends well beyond the field of biology and medicine, into new disciplines that will require translational and clinical research teams to establishment new collaborations.
This includes the development of a number of novel resources to align biomarkers to patient data and the most appropriate model(s). These research developments has enabled basic and mechanistic biologists to utilise the clinical and pre-clinical samples for downstream interrogation of the biology underpinning specific disease subtypes. A major barrier to more widespread alignment of human and mouse is inconsistencies in data analysis. To ensure that the wider research field can benefit from state-of-the-art disease-positioning developments from my research programmes, we have developed a freely-available human-mouse computational conversion application (MouSR: https://mousr.qub.ac.uk/) that streamlines transcriptional characterization between species for non-computational users. Furthermore, we continue to develop easy-to-use tool that enable users to interrogate the cellular source of their gene/signatures of interest, using an array of tissue processing methodologies (ConfoundR: https://confoundr.qub.ac.uk/).

Josep Tabernero and Elena Élez, are co-investigators and top-recruiters of the BEACON Trial. The practice-changing phase III BEACON trial evaluated targeted therapy for dual and triple targeted blockade in refractory BRAFV600E mCRC. Patients were randomly assigned (1:1:1) to receive the encorafenib plus cetuximab, encorafenib plus cetuximab plus binimetinib; or an irinotecan-based chemotherapy plus cetuximab as standard of care (SOC). The doublet combination was approved for adults with BRAFV600E mCRC and who have already undergone at least one prior treatment regimen (May 2020).
Hector Palmer’s Lab, in collaboration with clinical investigators are generating numerous PDX from CRC patients with different clinical profiles. A new GEMM has been generated to study hypermutant MSI CRC with BrafV600E mutation. A biobank of Msh2KO, BrafV600E and Msh2KO- BrafV600E organoids and syngeneic models is being created. Multiple rational drug combinations are showing activity controlling the growth of CRC PDXs and now we are testing our organoid and syngeneic mouse models. Finally, a comprehensive project to evaluate resistance to BRAFV600E inhibitors in collaboration with Novartis is currently running using PDX models collection. This is of high relevance since advanced CRC patients treated with anti-BRAFV600E-based therapies are currently progressing to treatments in several active clinical trials (e.g. BEACON trial).

My lab conducts frontier research to understand the role of the tumor microenvironment during colorectal cancer (CRC) progression, as well as the relation between stem cells (SCs) and cancer in the intestine. We perform fundamental research using innovative model systems and technologies on topics that are often clinically relevant. Over the past few years, my lab has devoted large efforts to understand the determinants of metastatic dissemination in CRC. We discovered that metastasis in CRC is a cancer cell non-autonomous process that depends on a TGF-beta-driven gene program expressed in stromal cells (Calon et al. Cancer Cell 2012, Calon et al. Nature Genetics 2015).
Moreover, we established a pre-clinical model of metastatic CRC in an immunocompetent background and demonstrated that checkpoint immunotherapies are effective against metastatic CRC in the presence of TGF-beta inhibitors (Tauriello et al. Nature 2018).
This research line holds a great potential to change the clinical management of CRC patients. We are leveraging our knowledge and expertise in order to:
- Develop methods to stratifycancer patients based on measuring the expression of stromal genes in patient samples
- Characterise the changes in the tumour microenvironment of metastatictriggered by inhibition of the TGF-beta pathway and treatment with checkpoint immunotherapies
- Develop novelbased on organoids to reproduce disease relapse. This model will allow pre-clinical evaluation of adjuvant therapies in a human-like model that mimics disease relapse in CRC after curative therapy.

Since October 2008 until May 2019, Dr Esteller was the Director of the Cancer Epigenetics and Biology Program (PEBC) in Barcelona. He is currently the Director of the Josep Carreras Leukaemia Research Institute (IJC) in Barcelona, Chairman of Genetics in the School of Medicine of the University of Barcelona, and an ICREA Research Professor.
His current research is devoted to the establishment of the epigenome maps in health and disease. As a well-recognized expert in the epigenetics field, Dr. Esteller is leading the epigenomic characterization of patient-derived xenograft (PDX) models developed by the ACRCelerate consortium using the latest platform from Illumina, the Human Methylation EPIC Beadchips that allows to interrogate the methylation status of almost a million of genome-wide distributed CpGs. Moreover, Dr. Esteller’s team in currently validating the first comprehensive mouse DNA methylation microarray that will be a key tool to characterize the epigenomic landscape of colorectal cancer mouse models developed under the umbrella of this project. The epigenomic data derived from both approaches, PDXs and murine models, will provide crucial information to improve the molecular stratification of colorectal cancer patients. Moreover, the knowledge generated with this strategy could be useful to identify novel targets for therapeutic intervention.

Research conducted in Livio Trusolino’s laboratory aims at exploring the mechanisms underlying tumour dependencies on defined oncogenic drivers or pathways and how such dependencies can be translated into therapeutic opportunities, with an emphasis on colorectal cancer. This goes along with the implementation of studies that correlate clonal competition with fitness effects as a means to understand whether variations in fitness landscape are dictated by clonal selection of heritable genomic traits or by non-genetic mechanisms impacting on cell phenotypes. To these objectives, Livio uses integrative multi-omic approaches and functional genomics in patient-derived xenografts and organoids.

PDX FINDER - open global cancer research portal to patient derived xenograft models
Patients-derived xenograft (PDX) mouse models are an important oncology research platform to study tumour evolution, drug response and personalised medicine approaches. However, because of the distributed and heterogeneous nature of PDX repositories, finding relevant models of interest to investigators is a challenge. The global success of PDX models will depend on their collective distribution and usage worldwide by academic and private sectors.
To facilitate PDX models discovery, EMBL-EBI and The Jackson Laboratory are co-developing PDX Finder – a comprehensive open global catalogue of PDX models and their associated data across resources. In support of this initiative, we coordinated the community initiative to develop the PDX Models Minimal Information Standard (PDX-MI) that defines the minimal information necessary for describing key elements of a PDX model including the clinical attributes of a patient’s tumour, methods of implantation, host strain, and quality assurance methods used for model validation.

The ultimate goal of the ACRCelerate Project is to improve the next generation of stratified trials for CRC, through accurate disease subtype positioning. This will be achieved with rapid and robust cross-validation of concepts across a suite of “state of-the art” models, at a rate and scale that would be unachievable by an individual center. These include new model systems with patient-derived xenografts (PDX), patient and PDX derived cell-lines (PDCL and PDXCL) and organoid models.
One aspect of the project is to perform preclinical testing of agents and combination therapies within defined target groups.
Bardelli’s group has developed a large collection of CRC cell lines, drug-resistant cells and tumour (patient or PDX-derived) derived cells. CRC cell lines have specific molecular features and will support the stratification of therapies that target cell intrinsic tumour mechanisms. They have performed a systematic screening with chemotherapeutic agents (5-fluorouracil, oxaliplatin, irinotecan metabolite) in a group of over 100 cell lines recapitulating the genomic landscape of colorectal cancer and plan to investigate on potential correlations between the genomic milieu and the pharmaco-response profiles obtained in different CRC models.
To begin mechanistically dissecting effective combinatorial therapies in CRC, in 2020 they reported how in CRC, KRAS G12C inhibitors needed to be combined with EGFR blocking agents in order to overcome drug resistance to these targeted agents. Most excitingly, the first patients treated with the proposed combination showed tumor regression on scans in January 2021, less than a year after our publication. Overall our preclinical experiments therefore continue to provide the rationale for innovative clinical trials.

MouSR - Molecular Subtyping Resource
Human-mouse computational conversion application
Generation of transcriptional data has dramatically increased in the past decade, driving the development of analytical algorithms that enable interrogation of the biology underpinning the profiled samples. However, these resources require users to have expertise in data wrangling and analytics, reducing opportunities for biological discovery by ‘wet-lab’ users with a limited programming skillset. Although commercial solutions exist, costs for software access can be prohibitive for academic research groups.
To address these challenges, we have developed an open source and user-friendly data analysis platform for on-the-fly bioinformatic interrogation of transcriptional data derived from human or mouse tissue, called Molecular Subtyping Resource (MouSR).
This internet-accessible analytical tool, enables users to easily interrogate their data using an intuitive ‘point-and-click’ interface, which includes a suite of molecular characterisation options including quality control, differential gene expression, gene set enrichment and microenvironmental cell population analyses from RNA sequencing.
The MouSR online tool provides a unique freely available option for users to perform rapid transcriptomic analyses and comprehensive interrogation of the signalling underpinning transcriptional datasets, which alleviates a major bottleneck for biological discovery.

ConfoundR
Interrogation of the cellular source of gene/signatures of interest
Precise mechanism-based gene expression signatures (GESs) have been developed in appropriate in vitro and in vivo model systems, to identify important cancer-related signalling processes. However, some GESs originally developed to represent specific disease processes, primarily with an epithelial cell focus, are being applied to heterogeneous tumour samples where the expression of the genes in the signature may no longer be epithelial-specific. Therefore, unknowingly, even small changes in tumour stroma percentage can directly influence GESs, undermining the intended mechanistic signalling.
Using colorectal cancer as an exemplar, we deployed numerous orthogonal profiling methodologies, including laser capture microdissection, flow cytometry, bulk and multiregional biopsy clinical samples, single cell RNAseq and finally spatial transcriptomics, to perform a comprehensive assessment of the potential for the most widely-used GESs to be influenced, or confounded, by stromal content in tumour tissue. To complement this work, we generated a freely-available resource, ConfoundR; https://confoundr.qub.ac.uk/ that enables users to test the extent of stromal influence on an unlimited number of the genes/signatures simultaneously across colorectal, breast, pancreatic, ovarian and prostate cancer datasets.
Findings presented here demonstrate the clear potential for misinterpretation of the meaning of GESs, due to widespread stromal influences, which in-turn can undermine faithful alignment between clinical samples and preclinical data/models, particularly cell lines and organoids, or tumour models not fully recapitulating the stromal and immune microenvironment. As such, efforts to faithfully align preclinical models of disease using phenotypically-designed GESs must ensure that the signatures themselves remain representative of the same biology when applied to clinical samples.

S-CORT
Stratification in Colorectal Cancer
Stratified medicine holds the promise to tailor appropriate treatments to patients by linking variables such as molecular or imaging phenotypes to clinical decisions. The aim of the combined effort of S-CORT is to better diagnose CRC in such a way as to increase the likelihood that the treatment with the highest chance of success, is prescribed to patients. It also aims to minimise the sometimes negative side effects associated with various therapies. In this comprehensive analysis, tissue taken from patients receiving surgery, radiotherapy and/or chemotherapy are analysed using techniques summarised above to identify signatures which will improve how those therapies are used going forward.
