Epidermal growth factor receptor after 40 years
Discussion meeting organised by Professor Mark A Lemmon FRS.
Sequencing of the epidermal growth factor receptor (EGFR) 40 years ago revealed how oncogenic viruses hijack cell growth control processes in cancer. We are only now beginning to understand the complexity of signalling by EGFR and its relatives and how best to target them in cancers. This meeting will illuminate exciting new perspectives on EGFR signalling in health and disease.

The challenge of curing cancer by targeting major driver oncogenes EGFR and RAS
Forty years ago, the intersection of studies of acutely transforming retroviruses and normal growth regulatory proteins led to the identification of major driver oncogenes responsible for causing a large proportion of human cancers, such as EGFR and RAS. Subsequent studies showed that these lay in the same signalling pathway, along with other major oncogenes such as BRAF, and suggested that they would make excellent targets for therapeutic intervention in oncology. EGFR inhibitory drugs have been approved for clinical use for over 20 years, but initially suffered from rapid evolution of drug resistance. Subsequent generations of EGFR inhibitors, such as osimertinib, have reduced but not eliminated this problem. RAS inhibitors took much longer to develop, gaining clinical approval in 2021, but are still plagued by rapid evolution of drug resistance, with currently licenced RAS inhibitory drugs failing to extend overall survival in lung cancer patients, although providing short-term benefit. At the start of this journey of discovery, it was assumed that removing the driver of tumour growth would result in cancer elimination, but this has turned out not to be the case. This has led to great interest in combining oncogene inhibitors with other modalities to improve the durability of responses. Oncogenic signalling not only promotes the proliferation and survival of cancer cells, but can also play a major role in suppressing anti-tumour immunity through several mechanisms. This provides a rationale for combination of oncogene targeted drugs with various types of immunotherapies, which will be explored further in this presentation. Dr Julian Downward FRS, Francis Crick Institute, UK
Dr Julian Downward FRS, Francis Crick Institute, UKJulian trained with Mike Waterfield and Robert Weinberg before setting up his own lab in 1989 at the Cancer Research UK London Research Institute. He moved to the Francis Crick Institute in 2016. His work focuses on the role played by major oncogenes such as RAS and EGFR in human cancer. He established that EGFR is the product of the erbB proto-oncogene and was responsible for mapping out the signalling pathways linking EGFR to RAS and downstream to the MAP kinase and PI 3-kinase pathways. He now focuses on novel approaches to targeting RAS mutant lung cancers, exploring the effects of RAS signalling on suppression of the immune system’s response to the tumour.

Lessons learned from the EGF receptor about transmembrane signalling mechanisms
Together, the seminal 1979 discovery that EGF stimulates in vitro phosphorylation of a 170 kDa membrane protein, the presumptive EGF receptor (EGFR), and the 1980 revelation that this protein kinase activity is specific for tyrosine revolutionised our understanding of how extracellular growth factors deliver intracellular signals, and immediately suggested how receptor tyrosine kinase (RTK) pathways might be usurped by oncogenic retroviral tyrosine kinases, such as SRC. In 1981 we showed that EGF stimulates tyrosine phosphorylation of EGFR and several other proteins in intact cells. The 1984 cloning of an EGFR cDNA provided a predicted EGFR protein sequence, which led to the demonstration that EGF treatment stimulates EGF receptor autophosphorylation on several tyrosines in vivo and also increases phosphorylation of the EGFR at Thr654 in the cytoplasmic juxtamembrane domain, a site shown to be phosphorylated by protein kinase C that downregulates EGFR kinase activity. Fifty-eight of the 90 tyrosine kinases in the human kinome are RTKs; many of these are mutated and activated in cancer. Since the early 2000s, >85 clinically approved TKIs have been developed for treating cancer, including IressaTM/gefinitinib, an EGFR inhibitor approved in 2003 for treatment of non-small cell lung cancer. The development and use of anti-phosphotyrosine antibodies for studying tyrosine phosphorylation encouraged us to generate monoclonal antibodies specific for the 1- and 3-isoforms of phosphohistidine. Our recent work using these antibodies to study histidine phosphorylation of proteins will be discussed. Our findings suggest that protein-histidine phosphorylation is perturbed in several different human cancer types, affording possible therapeutic opportunities. Dr Tony Hunter FRS, Salk Institute, USA
Dr Tony Hunter FRS, Salk Institute, USATony Hunter received his BA and PhD from the University of Cambridge and did postdoctoral studies there and at the Salk Institute. Since 1975 he has been on the faculty of the Salk Institute, where he is the Renato Dulbecco Chair. In 1979, through his work on tumour viruses, he discovered a new class of protein kinases that phosphorylate tyrosine in proteins, establishing that dysregulated tyrosine phosphorylation by an activated tyrosine kinase can cause cancer. Tyrosine phosphorylation is a reversible protein modification essential for the regulation of a wide variety of cellular processes in multicellular eukaryotes, including transmembrane signal transduction by surface receptors. Hunter’s work led to the realisation that aberrant tyrosine phosphorylation is causal in several types of human cancer, and this has led to the successful development of a large number of small molecule inhibitors that target disease-causing tyrosine kinases, known as TKIs, such as GleevecTM. |

When is a kinase not a kinase?
The PKC family of protein kinases have revealed many behaviours that inform us more broadly on the manner in which this class of regulator operates physiologically and in disease. This includes recent findings relating to: stalled substrate complexes, kinase specificity switching and pertinent to the presentation here, nucleotide pocket dependent conformational changes. The unexpected finding that a typical nucleotide pocket binding inhibitor of PKCa could promote/stabilize the priming phosphorylation of an otherwise unstable/poorly phosphorylated PKCa point mutant, provided compelling evidence that pocket occupation is important conformationally for the retention of these priming phosphorylations in cells, corroborating early in vitro data on sensitivity to dephosphorylation. This has impacted the interpretation of anomalous activation of the ERK pathway in response to BRaf mutant-selective inhibitors; it is also germane to pseudokinases, where many retain ATP binding capacity. In the case of the pseudokinase in the EGFR family, HER3, it has been shown that retention of ATP binding is critical for allosteric activation of HER2 through the productive asymmetric dimer. This offers opportunities for small molecule intervention as demonstrated in a hit from a library screen for HER3 binders. For PKC itself, this behaviour has stimulated investigation into the function of the penetrant PKCa mutation found in chordoid glioma. Contrary to expectations, this kinase inactive catalytic aspartate mutation (D463H) is a gain of function allele revealing a conformationally dependent effector output for PKCa and the inevitable prediction that activity drives negative feedback – more akin to a G-Protein and its ATPase activity. So when is a kinase not a kinase (as we know it)? Professor Peter J Parker FRS, Francis Crick Institute and King's College London, UK
Professor Peter J Parker FRS, Francis Crick Institute and King's College London, UKPeter has had a career-long interest in biological control mechanisms, in particular the properties and actions of protein kinases. This was sparked when an undergraduate in Oxford, permeated his graduate and post-doctoral training and led him to a senior post-doctoral position with Mike Waterfield working on the kinase activity of EGFR. Inspired by Nishizuka’s work he ran a parallel programme on PKC, setting the cornerstone for this complex family of lipid-activated protein kinases. The study of these kinases, their regulators, outputs and druggability has occupied much of Peter’s research career, with learnings infusing the field of inositol lipid metabolism and the broader kinase superfamily. |

Targeting the EGFR family in cancer
ErbB/EGFR family members play a role in driving the growth of a number of solid tumours. Studies on TGFa, discovered in 1978 as the second member of the EGFR ligand family, led to the concept of autocrine growth factor signalling. Therapeutic agents directed against two receptor family members, EGFR and HER2/ErbB2, show meaningful clinical benefit in a number of solid tumours including breast, lung, colorectal, gastric, head and neck, etc. Clinically approved agents can be divided into three general categories: small molecule tyrosine kinase inhibitors, monoclonal antibodies and their conjugates. Multiple laboratory studies implicate HER3/ErbB3 and HER4/ErbB4 as potential targets for drug development. Surprisingly, none of these attempts have led to an approved therapeutic agent. Despite the success of the EGFR or HER2 therapies, a number of patients will recur with metastases outside the primary tumour site. Notably several cancers including breast, lung, and melanoma frequently metastasize to the brain. Unfortunately, conventional therapies do not traverse the blood brain barrier. Novel approaches to deliver macromolecules across the blood brain barrier are being developed and show early promising clinical data that they may be successful.

Unlocking secrets of HER heterodimers
Dr Jura will present studies from her laboratory describing application of structural biology methods including X-ray crystallography and cryo-electron microscopy (cryo-EM) towards obtaining high resolution structures of human epidermal growth factor receptor (HER) tyrosine kinase signalling complexes. She will also discuss implications of these studies for signalling and therapeutic targeting. Her group’s research provided first structural insights into assembly of heterotypic kinase complexes between HER receptors by solving crystal structures of the EGFR/HER3 kinase domain complex in the wild type form and in the presence of HER3 oncogenic mutations. Following these findings, the Jura lab group developed methods for purification of full-length HER2 and HER3 receptors and their analysis by cryo-EM. This led to the first structure of the HER2/HER3 heterodimer, revealing its unique activation mechanism and explaining the activating effect of the most common HER2 oncogenic mutation, S310F, located in the extracellular domain. These studies also delineated structural basis for the binding of the HER2/HER3 complex to a therapeutic antibody trastuzumab (Herceptin). Most recent work from the Jura laboratory describes first cryo-EM structures of the HER4 homo- and HER2/HER4 heterodimeric complexes solved in the context of nearly full-length receptors. These studies shed light on the mechanisms of activation of these complexes by different growth factors and highlight presence of elaborate glycosylation modifications on HER4.

After her BSc (physics), Marisa became a keen biophysicist, subsequently training as cell biologist. As a PI since 2002, she focused on understanding how dysregulated Epidermal Growth Factor Receptor (EGFR) signals drive the development of lung tumours. Towards this goal, she developed a portfolio of single-molecule and super-resolution imaging methods, and data analysis routines aiming at determining in cells the structure of active and inactive EGFR macromolecular assemblies and their dysregulated versions in cancer EGFR mutants. Exploiting the ~3 nm resolution in cells afforded by these methods, a recent breakthrough is the discovery of an unsuspected signal amplification mechanism that could be targeted to slow tumour progression and increase the efficacy of drugs.

The generation of ligand-dependent differential outputs by the epidermal growth factor receptor
The epidermal growth factor receptor (EGFR) binds to different high-affinity ligands, such as EGF and TGF-α, initiating intracellular signalling that is subtly different. Cryo-EM analyses reveal that EGFR adopts similar dimeric conformations when bound to these ligands, but with differences in conformational variability. EGF and TGF-α appear to differ in their ability to maintain a specific conformation correlated with increased EGFR activity, particularly when an oncogenic mutation is present. This study suggests a molecular mechanism by which EGFR produces different responses depending on the bound high-affinity ligand.

Understanding GDNF-dependent neurotrophic signalling assembles
GDNF is made by glial cells in response to aging, damage and inflammation leading to neuroprotection by activation the RET receptor tyrosine kinase. GDNF also plays a key role in the developing enteric nervous system development and in kidney morphogenesis. The molecular mechanisms underpinning these distinct roles are not yet clear. GDNF acts with its GFRa1 co-receptor to signal through RET but can also engage the adhesion receptor NCAM and the proteoglycan syndecan-3. Structural efforts to understand these distinct GDNF-driven assemblies and their signalling outputs are revealing a surprising complexity. Recent structures will be presented together with efforts to develop GDNF mimetics as a new therapeutic modality. Professor Neil Q McDonald, The Francis Crick Institute, UK

The C elegans EGFR is a missing link that unifies EGFR and IR family activation mechanisms
It is generally accepted that ligand-induced dimerization is a key element in the activation of human EGFR. Nonetheless, there is evidence that unliganded dimers and/or oligomers of the receptor are relevant for EGFR activation at the cell surface. The precise role of these unliganded dimers is unclear, however, and none has been visualised structurally. Interestingly, unlike human EGFR, the Caenorhabditis elegans EGFR orthologue (LET-23) is always dimeric, even in the absence of ligand. It is clear that LET-23 activation is dependent on binding of its ligand (LIN-3), but activation appears to occur without alteration in the oligomeric state of the receptor – a situation that is also well known for the insulin receptor. Cryo-electron microscopy was used to determine the structure of the LET-23 extracellular region with- and without bound LIN-3, providing the first structural view of ligand-induced conformational changes within a pre-formed EGFR family dimer. In the unliganded dimer, unexpected interactions involving the C-terminal region hold the two intracellular kinase domains apart, preventing their allosteric activation. Ligand binding destabilises these interactions to allow the C-terminal legs to come together, which would allow activation of the intracellular kinase domains. Consistent with an autoinhibitory role for these C-terminal interactions, in vivo C elegans experiments show that weakening these interactions sensitises the receptor to its ligand. Our model for LET-23 activation has striking similarities to current models for insulin receptor activation, consistent with the similarities of their N-terminal ligand binding modules and modes of ligand binding.

From structure and mechanism to medicine: an allosteric inhibitor for EGFR L858R+ lung cancer
Mutations in the epidermal growth factor receptor (EGFR) are a common cause of non-small cell lung cancer. While osimertinib is highly efficacious in lung cancers with sensitising mutations in EGFR, there is a major unmet need for agents that overcome resistance to it and other covalent third-generation EGFR TKIs due to the C797S mutation. Furthermore, osimertinib extends overall survival in patients with exon19 deletions but offers no improvement in overall survival in patients with the L858R mutation relative to the first-generation inhibitors. Building on structural and mechanistic insights into the mechanism of EGFR regulation, we discovered allosteric inhibitors that bind the kinase in a manner that blocks its activity and disrupts formation of the activating asymmetric dimer. EAI-432 is a mutant-selective allosteric inhibitor that is effective against L858R and its common resistance variants, including T790M and C797S, while sparing WT EGFR. We are developing EAI-432 with the goal of improving outcomes for patients with EGFRL858R+ lung cancer. The compound is brain-penetrant and induces tumour regressions in multiple xenograft models at low doses (5-25 mg/kg). EAI-432 co-binds with osimertinib, allowing double-drugging of the mutant receptor. The distinct binding site and allosteric mechanism of EAI-432 confer exquisite kinome-wide selectivity and orthogonal resistance mechanisms as compared with osimertinib and other ATP-competitive TKIs, properties that are highly desirable in a combination agent. The compound has efficacy, mutant-selectivity, and pharmacokinetic properties that support its further development as a therapeutic agent for EGFRL858R+ lung cancer alone or in combination with osimertinib.

Air pollutants promote non-small cell lung carcinogenesis
A mechanistic basis for non-small cell lung cancer (NSCLC) initiation in never smokers, a disease with high frequency EGFR mutations (EGFRm), is unclear. Air pollution particulate matter (PM) is known to be associated with the risk of NSCLC, however a direct cause and mechanism remain elusive. We analysed 463,679 individuals to address the associations of increasing 2.5um PM (PM2.5) concentrations with cancer risk. We performed ultra-deep profiling of 247 normal lung tissue samples, analysed normal lung tissue from humans and mice following exposures to PM, and investigated the consequences of PM in mouse lung cancer models. Increasing PM2.5 levels are associated with increased risk of EGFRm NSCLC in England, South Korea and Taiwan. 18-33% of normal lung tissue samples harbour driver mutations in EGFR and KRAS in the absence of malignancy. PM promotes a macrophage response and a progenitor-like state in lung epithelium harbouring mutant EGFR. Consistent with PM promoting NSCLC in at-risk epithelium harbouring driver mutations, PM accelerates tumourigenesis in three EGFR or KRAS driven lung cancer models in a dose-dependent manner. Finally, we uncover an actionable inflammatory axis driven by IL1B in response to PM, in agreement with reductions in lung cancer incidence with anti-IL1ß therapy. These results shed light on the etiology of EGFRm lung cancer and suggest that oncogenic mutations may be necessary but insufficient for tumour formation. These data reveal a mechanistic basis for PM driven lung cancer providing an urgent mandate to limit air pollution. Importantly, the observation of a reduction in pollution-induced tumour growth upon anti-IL1ß treatment suggested that tumorigenesis may be prevented.

Assistant Professor Emilia Lim, The University of British Columbia, CanadaDr Emilia Lim is an Assistant Professor in the Department of Biochemistry and Molecular Biology at the University of British Columbia in Vancouver BC. Most recently, she completed her postdoctoral training with Dr Charles Swanton at the Francis Crick Research Institute, studying chromosomal instability and how it shapes lung cancer evolution. She currently leads an environmental oncogenomics group. Her research program concerns how environmental exposures disrupt normal cells to accelerate the initiation of age-related disease states such as cancer. Her team performs multi-omic investigations of how environmental pollutants co-opt molecular mechanisms to shape tissue landscapes into diseased states. This will be done with a view towards molecular disease prevention, revealing targets for screening and intervention. |

Panel discussion
Panel discussion with Professor Daniel J Leahy, Associate Professor Chiara Francavilla, Professor Daniel Hochhauser and Professor Linda J Pike. Professor Daniel J Leahy, University of Texas at Austin, USA
Professor Daniel J Leahy, University of Texas at Austin, USADr Daniel J Leahy is the former chair of the largest department in University of Texas at Austin’s College of Natural Sciences, the Department of Molecular Sciences. His research focuses on molecular mechanisms of cell signalling, examining the processes by which proteins and other molecules behave within living systems including molecular mechanisms that regulate growth in normal and malignant cells. Dr Leahy’s work on one family of signalling molecules—the epidermal growth factor receptor (EGFR) and human epidermal growth factor reception 2 (HER2)—has contributed to our understanding of how these molecules function in healthy people and in people with cancer. This research has influenced medical professionals’ strategies to treat cancers of the lung, breast, colon and gastric system. Before coming to University of Texas at Austin in 2016, he was a member of the faculty at Johns Hopkins University School of Medicine from 1993-2015. Associate Professor Chiara Francavilla, Technical University of Denmark, Denmark, and The University of Manchester, UK
Associate Professor Chiara Francavilla, Technical University of Denmark, Denmark, and The University of Manchester, UKChiara got her PhD in 2009 and after two postdoctoral positions in Copenhagen, Denmark, she started as Wellcome Trust Sir Henry Dale-funded research fellow at the University of Manchester (UoM), United Kingdom, in 2016. Since July 2023 Chiara is Associate Professor at the Technical University of Denmark with an honorary position at the UoM. Chiara’s team studies the regulation of cellular signalling in several mammalian cell models, particularly breast cancer models including patient samples, using a multi-disciplinary approach. By integrating mass-spectrometry-based omics methods with bioinformatics and functional assays in vitro and in vivo, Chiara’s research focuses on how:
Chiara’s research aims at identifying and characterising signalling proteins with key roles in cell survival which can be targeted for personalised intervention in human diseases. Professor Daniel Hochhauser, University College London Cancer Institute, UK
Professor Daniel Hochhauser, University College London Cancer Institute, UKProfessor Daniel Hochhauser is a medical oncologist specialising in the treatment of gastrointestinal cancer. His focus is on the investigation of the EGFR pathway in colorectal cancer and how this can modulate responses to anticancer therapy. Professor Linda J Pike, Washington University in St Louis, USA
Professor Linda J Pike, Washington University in St Louis, USADr Pike has worked in the area of signalling for over 4 decades. She did her thesis work in the laboratory of Robert J Lefkowitz, where she studied G protein-coupled receptors. She then moved to the laboratory of Edwin Krebs where she initiated her work on the EGF receptor. Her work has been focused on understanding how ligand binding can be used to understand structural and functional changes in the EGF receptor. Her recent studies have examined how extracellular domain mutations in the EGF receptor alter the binding and signalling of the seven different EGF receptor ligands. |
