2020 Development Fund Projects

– Understanding the impact of systemic immune tolerance caused by melanoma interacting with the liver microenvironment

Main applicants: Erik Sahai (Crick), Mala Maini (UCL)

Co-applicants: Rebecca Lee (Crick), Laura Pallett (UCL), Mariana Diniz (UCL)

Patients with liver metastases respond very poorly to checkpoint inhibitors (CPI) with both metastases within the liver and those at extra-hepatic sites progressing on therapy. We will study how liver metastases induce both local and systemic immune tolerance resulting in decreased response to CPI. Understanding of these processes will enable development of strategies to improve outcomes to CPI for patients with melanoma with liver metastases.

– Tracing and timing pre-cancerous clonal dynamics in normal tissues

Main applicant: Marnix Jansen (UCL)

Co-applicants: Kit Curtius (Barts), David Graham (UCL), Matthew Banks (UCL)

– The differential contribution of tumour infiltrating and circulating neutrophils to chemotherapy resistance in early breast cancers

Main applicant: Sheeba Irshad (KCL)

Co-applicants: Ilaria Malanchi (Crick), Shahram Kordasti (KCL)

Many patients with early breast cancers are treated with neoadjuvant chemotherapy (NACT).  Women with residual disease following NACT often suffer a poorer outcome, with early elapsed disease; and difficult to treat metastatic disease.   The immune cell populations and their functions within chemotherapy resistant residual disease are much less well understood.

Neutrophils constitute a significant part of the tumour microenvironment (TME). Traditionally, few studies have focussed on their role in tumour progression considering them to be hallmarks of acute inflammation with short survival time (3-24hr).  My co-investigator for this study, Dr Ilaria Malanchi has demonstrated that neutrophils specifically support metastatic initiation in the pre-metastatic niches of mouse models. In the context of the tumour microenvironment, neutrophilic recruitment and activation have been shown to have broad effects on tumour cells and the microenvironment, which include direct cellular injury from release of oxidants and granular constituents, remodelling of the extracellular matrix, release of pro-angiogenic products, and cross-signalling to other inflammatory cells and tumour stromal constituents.

We now seek to investigate the role and interaction of tumour associated and circulating neutrophils in chemotherapy resistant cancers across the different breast cancer subtypes.

– Evolution and ecology of oesophageal adenocarcinoma under neoadjuvant treatment

Main applicant: Trevor Graham (Barts)

Co-applicants: Melissa Schmidt (Barts), Marnix Jansen (UCL), Benny Chain (UCL)

Oesophageal adenocarcinoma (OAC) is the 8th most frequent cancer in Europe and remains challenging to treat with 40-55% of patients progressing on chemotherapy and 5-year survival of 12.6%.

In this pilot project we will make multi-omic genomic, transcriptomic, t-cell repotoire, and multi-marker immune profiling measurements of OACs at multiple time points (prior, during, and after therapy) in tumour tissue from OAC patients who are enrolled in a neoadjuvant therapy trial in Germany. We will then perform a detailed evolutionary analysis of these data, centred around tracking the size and emergence/disappearance of cancer clones over time, and the relationship of these evolutionary dynamics to tumour cell phenotypes and immune cell activity. We will use our data to parameterise mathematical models of tumour evolution to enable forecasting of individual tumour response to treatment.

The work is a collaboration between Dr Schmidt and Prof Graham at the Barts Cancer Institute (cancer genomics), Dr Jansen at UCL (pathology of OAC) and Prof Chain at UCL (immunogenomics).

– Targeted reversal of epigenetic silencing at specific tumour suppressor genes in lymphoma

Main applicant: Richard Jenner (UCL)

Co-applicants: Jude Fitzgibbon (Barts)

– Developing organotypic models of human osteosarcoma

Main applicant: Sibylle Mittnacht (UCL)

Co-applicants: Wenhui Song (UCL), Ilaria Malanchi (Crick)

Osteosarcoma (OS), despite rare, is a key cause of cancer death in children and young adults. Progress in rare cancers critically relies on tools and disease models that appropriately reflect their clinical presentation for conceptual studies and therapeutics testing. Ex vivo complex organotypic models that reflect the genetic and tissue heterogeneity of disease have been developed in many epithelial cancers but this has not been successful in OS thus far.

The proposed work seeks to combine front-line tissue engineering expertise in 3D scaffold- guided growth of human bone by the Song laboratory at the UCL Centre for Biomaterials in Surgical Reconstruction and Regeneration, translational therapeutic and cancer cell biology expertise by the Mittnacht laboratory at the UCL Cancer Institute and expertise in the study of tumour microenvironmental interactions by the Malanchi laboratory at the Francis Crick Institute, to build an organotypic platform for the propagation of patient-near orthotopic models of human OS.

The proposed work fills a recognized technology gap in OS research that is limiting therapeutics discovery and conceptual studies in this disease.

2019 Development Fund Projects

– Deep Learning of High Dimensional Genetic, Immune and Clinical Parameters to Predict Patient Response to Immune Checkpoint Blockade

Main applicant: Francesca Ciccarelli (Crick/KCL)

Co-applicants: Jo Spencer (KCL), Daniel Hochhauser (UCL), Manuel Rodriguez-Justo (UCL) and Kai-Keen Shiu (UCL)

– Connecting Single-Cell Ligands, Receptors, and Signals in Tumour Microenvironment Organoids

Main applicant: Chris Tape (UCL)

Co-applicants: Vivian Li (Crick)

Tumours are heterogeneous mixtures of different cell-types. In addition to mutated cancer cells themselves, the tumour microenvironment contains multiple stromal and immune cells that each contribute to a patient’s cancer. While we now understand the cellular composition of tumours relatively well, how different cell-types collectively integrate to drive cancer is poorly defined.

Our ignorance of cell-cell communication in the tumour microenvironment largely stems from our inability to simultaneously measure ligands (cues), receptors (transducers), and signals (effectors) across all cells in a tumour. Without such data it is incredibly challenging to ‘connect’ mutations in cancer cells with deregulated phenotypes in stromal and immune cells.

To address this, the UCL Cell Communication Laboratory ( have developed a novel mass-cytometry (CyTOF) technology to measure single-cell post-translational modification (PTM) signalling in organoid models of the colorectal cancer (CRC) tumour microenvironment. While incredibly powerful for understanding PTM signalling, CyTOF data cannot describe the 1,000s of putative cell-type specific ligands or receptors responsible for transducing each signal. As a result, we cannot connect signals between cancer, stromal, and immune cells in the tumour microenvironment.

The aim of this CRUK City of London Development Fund project is to integrate our single-cell PTM technology (CyTOF) with single-cell ligand and receptor transcriptomics (10x Genomics). By simultaneously measuring cell-type specific ligand / receptor expression and PTM signalling in organoid models of the CRC tumour microenvironment (in collaboration with Vivian Li Lab, Francis Crick Institute), this will allow us to ‘connect’ cell-cell signalling across the tumour microenvironment.

– Targeting the Tumour Microenvironment to Enhance Immunotherapy: A Cross-Disciplinary Approach to Assessing Treatment Efficacy

Main applicant: Kairbaan Hodivala-Dilke (Barts)

Co-applicants: Ralph Sinkus (KCL)

Enhancing drug efficacy by manipulating the tumour microenvironment is a primary goal of our laboratory research. We have published that intravenous administration of the integrin-targetting agent, low dose Cilengitide (ldCil), increases tumor angiogenesis and drug delivery whilst reducing hypoxia and desmoplasia in gold standard preclinical models of lung and pancreatic (KrasLSL-G12D/+;p53R172H/+;PDXCre, KPC) cancers. Together this approach reduces tumour growth and metastasis, whilst extending survival (Reynolds et al., Nature Medicine, 2009; Wong et al., Cancer Cell 2015). We have also collaborated with medicinal chemists who have developed a second generation orally available agent, Agent X, currently under patent application. Our new data indicate that combination treatment including Agent X also reduces desmoplasia.

Magnetic resonance elastography (MRE) is an innovative non-invasive imaging technique that not only determines the presence of a tumour but also identifies the desmoplastic pathophysiological status of cancers and can be used to assess the anti-desmoplastic efficacy of cancer therapies. Our partner in this application, Ralph Sinkus’s has developed methods of improved MRE technologies across multiple cancer types has provided the opportunity to utilize MRE as a tool for therapy efficacy (Fovargue et al., NMR Biomed. 2018; Jamin et al., Cancer Res 2015).

Through this City of London Development Fund we now have the opportunity to join forces from Barts and Kings to examine the efficacy our new anti-cancer strategy using state of the art imaging thus bringing added-value to this cross institutional collaboration.

– CAESAR: Comprehensive Analysis of Epigenetic Heterogeneity in SARcoma

Main applicant: Iben Lyskjaer (UCL)

Co-applicants: Adrienne Flanagan (UCL), Stephan Beck (UCL) and Peter Van Loo (Crick)

Despite progress in the histological classification of the different subtypes of sarcoma, the clinical outcome of patients with the majority of these subtypes has not improved over the last 40 years. To change this, there is a need to understand the molecular basis of sarcoma in the context of clinical presentation, outcome and response to therapies.

Deep sequencing of cancer genomes has revealed complex patterns of inter- and intra-tumour heterogeneity, providing insight into a tumour’s evolutionary trajectory and is starting to inform on patient prognosis and therapeutic decisions. The main clinical consequence of tumour heterogeneity and clonal evolution is the emergence of resistance to systemic drug therapy. Epigenetics has been shown to contribute to intra-tumour heterogeneity and evolution, as first reported in haematological malignancies, by measuring DNA methylation at single-nucleotide level using Reduced-Representation Bisulfite Sequencing (RRBS).

This study aims to generate a comprehensive profile at base pair resolution of the DNA methylation heterogeneity in osteosarcoma tumours and for the first time determine if locally disordered methylation exists in osteosarcoma. Building on the samples already collected and submitted to the 100,000 Genomes project, which includes whole genome sequencing of up to 8 samples per osteosarcoma, we will interrogate DNA methylation heterogeneity at a single nucleotide level using enhanced RRBS targeting over 4 million CpG dinucleotides in CpG-rich regions of the genome. Further, we will characterise the epigenetic tumour evolution in osteosarcoma tumours by looking at multiple samples from each tumour lesion, and determine associations between heterogeneity and the presence of particular driver mutations by using WGS data from the 100,000 Genomes Project.

– Intra Tumour Heterogeneity at the Level of Ploidy: A Need to Re-Evaluate Copy Number Inference from Bulk DNA Profiling

Main applicant: Maxime Tarabichi (Crick)

Co-applicants: Nischalan Pillay (UCL), Peter Van Loo (Crick), Kevin Bryson (UCL), Andrew Feber (UCL) and Marnix Jansen (UCL)

Most cancer evolution studies, because they rely on bulk DNA sequencing data, are inevitably compromised by ambiguous estimates of tumour ploidy.

Aberrations in ploidy and in particular whole genome doubling are macro-evolutionary events that are associated with increased fitness of cancer cells and poor prognosis. The largest pan-cancer bulk DNA sequencing studies to date have relied on ploidy estimates derived in silico, which are ambiguous and often incorrect. The problem arises from the fact that, in theory, multiples of 2 times the ploidy are mathematically equivalent solutions to fit the data, and although hints in the data can help select between the various potential solutions, this exercise remains hand-wavy. In addition, tumours can show heterogeneity at the level of ploidy, containing multiple populations with very different ploidy values, which is not modelled by current copy number inference methods.

Hence, our current pan-cancer picture of heterogeneity at the level of copy number and ploidy is challenged, and, although previous and recent results strongly support the use of systematic experimental ploidy validation to inform sequencing-based copy number callers, this still has to become good practice in the field. This is especially relevant and timely for large whole genome sequencing programs such as the 100,000 genomes project, but also for all DNA-profiling-based studies of cancer evolution and intra tumour heterogeneity.

This is why we aim to develop standards for the field by benchmarking ploidy estimated from bulk sequencing against experimental ploidy using FACS, single cell sequencing and digital imaging; and study the extent and spatial mapping of intra-tumour heterogeneity at the level of ploidy. This will be done across multiple cancer types, with a particular focus on undifferentiated sarcomas, which were recently shown to display high amounts of inter- and intra-tumour heterogeneity at the level of ploidy.

– A Novel Approach for Identifying Neoantigens from Cancer Cell-lines and Organoids

Main applicant: Faraz Mardakheh (Barts)

Co-applicants: Chris Tape (UCL)

Immunotherapy has revolutionised the outlook on treatment of various cancers in recent years. Several strategies have been developed for immunotherapy, majority of which ultimately depend on presence of neoantigens, tumour-specific antigens which arise from coding mutations that get translated and presented on the surface of the cells in form of peptides associated with Human Leukocyte Antigen-I (HLA-I). The ability to detect and monitor these neoantigens is critical, not only for better understanding the process of cancer cell detection by the immune system, but also for devising novel immunotherapies against cancer such as personalised vaccines. Despite years of research, however, neoantigen discovery and validation remains a daunting problem in the cancer biotherapeutics field.

The most common method for neoantigen discovery is in silico prediction of neoantigens from bulk tumour sequencing data. Although relatively easy to implement, the actual success rate of in silico methods for predicting neoantigens that can elicit an immune response remains very low. Direct identification of neoantigens by mass spectrometry (MS) represents an alternative to in silico based prediction. However, current available methods either suffer from lack of specificity, or are labour-intensive and require large quantities of input material, thus rendering their widespread use challenging. In this project, we propose to develop a novel approach that overcomes these major limitations, enabling rapid MS based identification of HLA-I-bound neoantigens, with high specificity, from a variety of live cancer models. As a proof-of-concept, we will then apply our method to analysis of neoantigens a panel of patient-derived colorectal cancer organoids grown in 3D culture.

– Exploring How Rho Regulated Kinases Modulate the Immune Landscape in Colorectal Tumours

Main applicant: Angus Cameron (Barts)

Co-applicants: Shahram Kordasti (KCL)

Immunotherapy has provided new hope for many cancer patients, with the potential to treat or cure even advanced metastatic disease. Although considered a huge breakthrough, immunotherapy only currently works in a subset of patients. Identifying ways to predict which patients will respond and approaches to sensitise non-responders, are critical next steps to extend impact. In colon cancer, immunotherapy ‘checkpoint inhibitors’ have already been approved for use in a subset of cancer patients who show high mutation rates (MSI+ tumours). Immunoscore – a quantitative assessment of the immune infiltrate in tumours – is also emerging as a powerful indicator of response to immunotherapy in colon cancer. As a consequence, interventions which modulate the immune infiltrate are of huge interest as they could be used to expand the group of patients who could benefit.

Our multidimensional and in vivo data indicate that Rho effector kinases may suppress tumour growth and promote an anti-tumour immune landscape. In this project, we wish to assess the immune cell repertoire in colorectal tumours induced in Rho effector knockout mice, to assess a novel mechanism to predict or modulate immunotherapy responses. We will use state-of-the-art Mass Cytometry (CyTOF) and tumour phenotyping to examine a broad range of immune cell types in colon tumours from our novel in vivo models. Our preliminary data suggest that specific Rho effectors may promote infiltration of tumours with CD8+ T-cells; intervention by activating or inhibiting this pathway would be expected to modulate both the immune infiltrate and response to immune checkpoint inhibition. This study will lay the ground work for the development of novel therapies to use in conjunction with existing immunotherapy drugs.

– Exploring Order in Chaotic Cancer Genomes

Main applicant: Nicholas McGranahan (UCL)

Co-applicants: Sarah McClelland (Barts)

– Non-invasive Imaging of Immune-mediated Tumour Ferroptosis

Main applicant: Timothy Witney (KCL)

Co-applicants: Crispin Hiley (UCL)

Ferroptosis is a morphologically and biochemically distinct form of regulated cell death that results from the excessive peroxidation of polyunsaturated fatty acids. Ferroptotic cell death is catalysed by iron and if left unregulated results in a chain reaction of lipid-derived reaction oxygen species (ROS) and eventual membrane destruction. Glutathione metabolism and antioxidant capacity mediate the sensitivity of tumours to ferroptosis through the combined activity of glutathione peroxidase and the cystine/glutamate transporter, xCT. Recently it has been shown that that immunotherapy-activated CD8+ T-cells induce ferroptosis-specific lipid peroxidation in tumour cells. T-cell immunity was enhanced by immune checkpoint blockade through a mechanism of interferon gamma release and subsequent xCT downregulation.

We are currently evaluating a novel PET imaging agent, [18F]FSPG, as a non-invasive marker of the tumour redox microenvironment. [18F]FSPG is taken up by tumour cells via xCT, providing a non-invasive measure of its activity. In this City of London Centre Development Project, we will monitor the efficacy of T-cell immunotherapy with [18F]FSPG in animal models of lung cancer. In genetically-modified animals and in patient-derived xenografts, we will image tumour-induced ferroptosis with [18F]FSPG following checkpoint blockade. Tumour-associated T-cell infiltration, activation and dysfunction will be assessed ex vivo along side lipid peroxidation as a marker of ferroptosis. Together, this will provide a rapid, whole-body assessment of the treatment efficacy for these novel immunotherapies.

– Identification of Novel Mechanisms of Cancer Immunoevasion

Main applicant: Paola Scaffidi (Crick)

Co-applicants: Francesca Ciccarelli (KCL), Gabriella Ficz (Barts), Julian Downward (Crick)

Immuno-surveillance is a critical tumour-suppressive mechanism that transformed cells need to evade to establish a full-blown cancer. Many immunoevasive strategies employed by cancer cells rely on aberrant transcriptional regulation of immunomodulatory molecules, implicating chromatin and DNA methylation in these processes.

Despite the recent success of immune checkpoint inhibitors, a significant fraction of patients do not respond to the therapy, suggesting that cancer cells likely exploit yet unidentified immunoevasive strategies. Using a unique experimental model, we have identified chromatin regulators whose inactivation favours the transition from an immunogenic to an immunoevasive phenotype.

We now propose to dissect the processes underpinning this transition, assess their prevalence in various cancer types, and provide a proof of principle that interfering with the identified mechanisms synergizes with other therapies.
