Functional genomics for rational tumor and immune cell combination therapy

Kép

Our Focus

Tumour heterogeneity, immune dysfunction and therapy resistance are among the most substantial challenges that limit durable benefit of cancer therapies. Using powerful function-based genomics, we screen for novel therapeutic targets to tackle those clinical problems. We develop rational combinatorial cancer treatments, which target both cancer and immune cells, thereby simultaneously eliminating the patient’s tumour and harnessing the immune system. This has already culminated in new concepts that we are translating to the benefit of the patient. 

About Daniel Peeper

My Research

Daniel Peeper is the Head of the Department of Molecular Oncology & Immunology and chairs both the Scientific Faculty Council and the Translational Research Board at the Netherlands Cancer Institute (NKI). He holds a professorship in Functional Oncogenomics at the VU University Medical Center (VUmc) and was elected as member of Oncode (a funded network of elected scientists in fundamental oncology from across the Netherlands).

Peeper studied Medical Biology at the VU University and received his PhD in the laboratory of Alex van der Eb at the University of Leiden (1994), for his work on adenoviral oncoproteins and cell cycle proteins. He received his postdoctoral training in the laboratories of Mark Ewen (Dana-Farber Cancer Institute, Harvard Medical School, Boston) and René Bernards (NKI). In 2002, Peeper became Assistant Professor and three years later Associate Professor at NKI. Also in that year, he was elected as an EMBO Young Investigator.

In 2002 and 2006, he received NWO VIDI and VICI awards, respectively for his functional oncogenomic studies. In 2007, he received the first KWF Queen Wilhelmina Award, by her Majesty the Queen Beatrix and the minister of Education, for his work on melanoma in collaboration with W. Mooi. In the same year, he received the Society for Melanoma Research Jr. Researcher Award. In 2008, Peeper was appointed affiliate Professor at the VUmc and was elected as EMBO member. In 2013, he received, together with colleagues including A Berns and M Stratton (Sanger Inst.), an ERC Synergy grant (€15 million) for the development of combinatorial cancer therapy. In 2015, he received the Outstanding research award by the Society for Melanoma Research and in 2016 he was elected to become a member of Academia Europaea. In 2017, he was invited to join Oncode.

Peeper has been a member of the European Association for Cancer Research (EACR) Board since 2013, and he also serves on the EACR Conference committee.

Highlights of the Peeper lab include their discoveries that a genomic screen for anoikis resistance can be used to identify metastasis genes (Nature 2004); that Oncogene-Induced cellular Senescence (OIS) serves as a potent in vivo tumor suppressor mechanism limiting cancer progression (Nature 2005; New Engl J Med 2006); the identification of several OIS-associated oncogenes (Nat Cell Biol 2005; Nat Rev Cancer 2006); that OIS is associated with the activation of an inflammatory transcriptome (Cell 2008; Nat Rev Cancer 2009; Genes Dev 2010); the identification of a novel candidate melanoma suppressor gene (EMBO J, 2011) and of a key mechanism of human melanomagenesis involving abrogation of OIS by reduction of PTEN expression (Genes Dev 2012). His laboratory also identified a prognostic breast cancer genetic signature and a factor essential to drive metastasis (PNAS 2013) and discovered that pyruvate dehydrogenase kinase (PDK1) acts as a critical switch for the execution of OIS and serves as an attractive drug target in melanoma (Nature 2013). Peeper and his team demonstrated the power of in vivo shRNA dropout screens for drug target identification (Cell Rep. 2014, Oncotarget 2016) and discovered a new mechanism mediating broad resistance to targeted therapy in melanoma (Nature Commun 2014). They also identified multiple resistance mechanisms to BRAF targeted therapy in a melanoma patient (EMBO Mol Med 2015) and developed a new bioinformatic tool to determine copy number alterations in cancer (Genome Biol 2015).

In addition, they established a large melanoma PDX platform that they used to identify a novel resistance mechanism of melanoma to BRAF inhibition (Cell Rep. 2016), and identified a prognostic genetic network driving human breast cancer (Oncotarget, 2017). Recently, they dissected the mechanism of cancer drug addiction and provided PoC of how this vulnerability may be used clinically (Nature 2017). Most recently, his lab developed a new concept for rational treatment combination: in collaboration with the biotech company Genmab it was demonstrated that melanoma intratumor heterogeneity is effectively targeted by a combination of an AXL-ADC (antibody-drug conjugate) and BRAF pathway inhibitors. By attacking distinct tumor subpopulations, these treatments act in a cooperative fashion, ensuring more durable responses (Nature Medicine 2018).

Transcription dynamics, single-molecule imaging

Kép

Our Focus

Gene expression is tightly regulated to ensure that genes are transcribed in the right cell at the right time. Yet, even genetically-identical cells in the same differentiation state and in the same environment exhibit considerable variability and fluctuations in the transcriptional process. This stochastic gene expression variation can influence important cell fate decisions and can also contribute to heterogeneity in tumours. A major source of stochastic gene expression heterogeneity is transcriptional bursting, where genes are transcribed during short periods of high gene activity interspersed by periods of inactivity. The origin and regulators of bursting remain largely unknown. Our lab aims to understand the regulatory mechanisms of transcriptional bursting in single cells. We use a range of single-molecule imaging techniques to directly observe the stochastic behaviour of regulatory factors and the process of transcription, as these dynamically occur inside living yeast and mammalian cells. We reveal how bursting is regulated by transcription factor binding dynamics, transcription factor clustering, enhancer-promoter interactions, chromatin, and DNA supercoiling. In addition, we are starting to apply our live-cell imaging approaches to study the function of stochastic heterogeneity in for example cancer plasticity.

Mouse models of breast cancer

Kép

Our Focus

My group studies human breast cancer development and progression, as well as therapy response and resistance, in genetically engineered murine models (GEMMs) and patient-derived tumour xenograft (PDX) models. We have developed models for BRCA1/2-associated breast cancer, invasive lobular carcinoma (ILC), ductal carcinoma in situ (DCIS) and oestrogen receptor (ER) positive breast cancer. These models are used to (1) study tumour cell-intrinsic and -extrinsic mechanisms of breast cancer development and progression; (2) develop novel therapeutic strategies for prevention and treatment of breast tumours; (3) study mechanisms of acquired resistance to targeted therapeutics. 

About Jos Jonkers

My Research

Jos Jonkers performed his PhD research (on retroviral insertional mutagenesis screens to identify oncogenes involved in lymphoma progression) in the group of Anton Berns at the NKI. In 1996 he became a postdoc in the Berns lab, where he developed GEMMs of BRCA1/2-associated breast cancer. In 2002, he joined the lab of Allan Bradley at the Wellcome Trust Sanger Institute to develop platforms for DNA copy number analysis of mouse tumors. He became a junior group leader at the NKI in 2003; was appointed as permanent staff member in 2008; and became Head of the Division of Molecular Pathology in 2012.

Major breakthroughs were:

  1. development of GEMMs of ILC and BRCA1/2-associated breast cancer

  2. identification of multiple mechanisms of therapy resistance in BRCA1-deficient breast cancer

  3. development of functional assays for classification of BRCA1 variants of unknown clinical significance

  4. development of CRISPR/Cas9-based non-germline GEMMs of breast cancer

Experimental biomedical genetics

Kép

Our Focus

Our group uses genetics in haploid human cells to construct a genetic wiring map for human cells and to study important outstanding questions in cell biology. To achieve this, we measure quantitative cellular traits in haploid cells carrying a gene-disruptive mutation and apply sequencing to link millions of mutations in parallel to cellular phenotypes.  

  

Whereas interesting findings can be derived from individual experiments, we have assigned genetic regulators to >160 quantitative phenotypes enabling comparative analysis. These comparisons point out specific regulators that affect only a limited number of traits and broad genetic regulators affecting many traits and can be used to cluster genes with similar phenotypic output.  

  

Next to a loss-of-function approach we have also studied a compendium of cellular phenotypes using a recently developed gain-of- function approach. Using both methods, we have recently identified new biological processes that we are characterizing further: new pathway for the synthesis of triglycerides, a p53-independent pathway for the induction of apoptosis by DNA damage, a new pathway for cellular iron uptake and a new co-activator complex that activates a large series of developmental transcription factors.  

About Thijn Brummelkamp

My Research

Thijn Brummelkamp received his Msc in biology from the Free University in Amsterdam, in 1998. He did his graduate research at The Netherlands Cancer Institute in the laboratory of René Bernards and received his PhD cum laude from Utrecht University in 2003. After his PhD he was appointed as group leader (Whitehead Fellow) at the Whitehead Institute for Biomedical Research in Cambridge, USA. In 2011 his laboratory moved to the Netherlands Cancer Institute in Amsterdam and he became adjunct PI at Center for Molecular Medicine (CeMM) in Vienna. Thijn has co-founded the biotech companies Haplogen GmbH (Vienna) and Scenic Biotech (Amsterdam).

He developed and applied technologies for genetics in cultured human cells (shRNA libraries and genetics in haploid mammalian cells) that are widely used in biomedical research. He identified a new class of intracellular receptors for highly pathogenic Ebola and Lassa viruses, studied the principles of synthetic lethal interactions in human cells, identified genes needed for glycosylation of alpha-dystroglycan and mutated in Walker-Warburg syndrome and assigned a function to the cylindromatosis tumor suppressor gene.

Functional Cancer Genetics

Kép

Our Focus

The most formidable obstacle in the treatment of cancer is the emergence of therapy resistance. Combination therapies can help fight therapy resistance, but with an arsenal of over 1000 cancer drugs in clinical development, the number of possible combinations seems nearly endless. In my laboratory we employ functional genetic screens to find powerful combinations of cancer drugs by exploiting the concept of "synthetic lethality". Using CRISPR/Cas9-based genetic screens focused on druggable gene families, we search for genes whose inactivation is particularly synergistic with clinically-relevant cancer drugs. Such screens can identify drug combinations that are far more powerful than the sum of the two single agents. We aim to understand the molecular rationale for the observed synergy between two cancer drugs. Once we have insight into the molecular mechanism, we aim to bring such rationally-designed combinations to the cancer clinic through collaboration with clinicians in our comprehensive cancer centre.

About René Bernards

Name

René Bernards

Position
Oncode Investigator at NKI
My research

René Bernards studied adenovirus transformation for his PhD research with Alex van der Eb in Leiden. He joined the laboratory of Robert Weinberg at the Whitehead Institute in Cambridge, USA for his postdoctoral training. He was appointed assistant professor at the Massachusetts General Hospital Cancer Center in 1988. In 1992 he joined the Netherlands Cancer Institute in Amsterdam. In 1994 he was also appointed part time professor of molecular carcinogenesis at Utrecht University, The Netherlands.

During his PhD research, he showed that the difference between oncogenic and non-oncogenic adenoviruses was primarily due to their differential ability to switch off the expression of MHC class I antigens, allowing evasion of T cell immune responses. During his postdoctoral work, he showed that downregulation of MHC class I antigens is also a property of the MYCN oncoprotein and, in collaboration with Stephen Friend, isolated the first tumor suppressor gene, RB1.

After returning to Amsterdam in 1992, his major scientific accomplishments include the development of MammaPrint, the first molecular diagnostic test for personalized treatment of breast cancer that has been used clinically since 2004 to select patients for adjuvant therapy. Recently, MammaPrint was validated in a large phase III clinical study, which demonstrated that over 250,000 women in the EU and US that are treated with chemotherapy annually can safely forego this toxic treatment without loss of survival benefit.

His laboratory also developed the first shRNA vector for gene silencing in mammalian cells and used this vector to create the first genome-scale library of shRNA vectors, enabling genome-wide loss of function genetic screens in mammalian cells. His laboratory has used this vector collection to identify the PI3K pathway as a major determinant of resistance to herceptin in breast cancer and to identify the CYLD tumor suppressor gene as a regulator of NF-kB signaling, which suggested a strategy to treat cylindromatosis. His laboratory also used genetic screens to identify a number of particularly powerful drug combinations for the treatment of cancer, based on the concept of synthetic lethality. This work identified the combination of a BRAF inhibitor and an EGFR inhibitor as effective for the treatment of BRAF mutant colon cancer, a combination that was FDA and EMA approved in 2020. There are currently multiple clinical trials ongoing that test the efficacy of the combination therapies suggested by genetic screens from his laboratory.

He has co-founded four companies: Prolifix (developed belinostat for treatment of peripheral T cell lymphoma), Agendia (developed MammaPrint for breast cancer diagnosis), Qameleon Therapeutics (Qamelostat for treatment of BRAF inhibitor-resistant melanoma) and Oncosence (pro senescence therapy for cancer).

During his PhD research, he showed that the difference between oncogenic and non-oncogenic adenoviruses was primarily due to their differential ability to switch off the expression of MHC class I antigens, allowing evasion of T cell immune responses. During his postdoctoral work, he showed that downregulation of MHC class I antigens is also a property of the MYCN oncoprotein and, in collaboration with Stephen Friend, isolated the first tumor suppressor gene, RB1.

After returning to Amsterdam in 1992, his major scientific accomplishments include the development of MammaPrint, the first molecular diagnostic test for personalized treatment of breast cancer that has been used clinically since 2004 to select patients for adjuvant therapy. Recently, MammaPrint was validated in a large phase III clinical study, which demonstrated that over 250,000 women in the EU and US that are treated with chemotherapy annually can safely forego this toxic treatment without loss of survival benefit.

His laboratory also developed the first shRNA vector for gene silencing in mammalian cells and used this vector to create the first genome-scale library of shRNA vectors, enabling genome-wide loss of function genetic screens in mammalian cells. His laboratory has used this vector collection to identify the PI3K pathway as a major determinant of resistance to herceptin in breast cancer and to identify the CYLD tumor suppressor gene as a regulator of NF-kB signaling, which suggested a strategy to treat cylindromatosis. His laboratory also used genetic screens to identify a number of particularly powerful drug combinations for the treatment of cancer, based on the concept of synthetic lethality. This work identified the combination of a BRAF inhibitor and an EGFR inhibitor as effective for the treatment of BRAF mutant colon cancer, a combination that was FDA and EMA approved in 2020. There are currently multiple clinical trials ongoing that test the efficacy of the combination therapies suggested by genetic screens from his laboratory.

He has co-founded four companies: Prolifix (developed belinostat for treatment of peripheral T cell lymphoma), Agendia (developed MammaPrint for breast cancer diagnosis), Qameleon Therapeutics (Qamelostat for treatment of BRAF inhibitor-resistant melanoma) and Oncosence (pro senescence therapy for cancer).

Controlling cancer by RNA

Our Focus

By developing innovative genomic, genetic, and proteomics tools, we set to identify novel cellular vulnerabilities that can be exploited for cancer (immune) therapies. In recent years, we have made major discoveries in mRNA translation in cancer, particularly in the context of amino acid availability to the tumour. We demonstrated that despite restrictive amino acid availability, protein production is maintained in the cancer cells, albeit with a high frequency of specific mistakes. We coined this phenomenon “Sloppiness” and showed that its outcome is the production of aberrant proteins and the presentation of neo-epitopes at the surface of cancer cells. These neoepitopes can serve as targets for immunotherapy. Currently, we use genetic tools to underpin genetic drivers of Sloppiness and employ immunological tools to utilize this knowledge for novel therapeutic approaches.

My Research

Reuven Agami started his research career as a PhD student working on the c-Abl kinase protein and apoptosis in the lab of Yosef Shaul at the Weizmann Institute of Science, Israel. In 1998 he moved to The Netherlands Cancer Institute, Amsterdam, as a postdoc fellow working on initiation and maintenance of DNA damage responses. In 2001 he began his own lab at the division of tumor biology at the Netherlands Cancer Institute working on stable inactivation of human genes by RNA interference as well as microRNAs. In 2008 he was chosen to become a division head of Gene regulation at the Netherlands Cancer Institute, Amsterdam. In 2009 he became professor at the department of Genetics, Erasmus medical center in Rotterdam. In 2014 he moved to head the division of Biological Stress Response at the Netherlands Cancer Institute, and since 2017 he is heading the division of Oncogenomics at the Netherlands Cancer Institute.

Major breakthroughs of Reuven Agami were the discovery of c-Abl/p73 interaction and its role in cell cycle arrest and apoptosis during his PhD, the role of cyclin D1 degradation following DNA damage during his Postdoc, as well as the development of pSUPER, the first RNAi vector for stable suppression of gene expression in mammalian cells, and the establishment of cancerous roles of numerous microRNAs and RNA binding proteins using novel genetic screening approaches as a young group leader. As a more senior investigator he contributed to understanding the role of alternative cleavage and polyadenylation of mRNAs (APA) in human disease, the functional role of regulatory DNA elements in cancer, the connection between transcription and translation, and finally the identification and utilization of amino acid shortages in cancer.

Immune cells and macrophages in therapeutically challenging tumors

Kép

Our Focus

Our lab mission is to identify the co-evolving features fuelling tumour cells and myeloid cell subsets pro-tumorigenic interactions in the course of cancer progression, therapy response and tumour relapse. Our lab extensive background in glioblastoma and hepatocellular carcinoma has uncovered cell autonomous and non-cell autonomous mechanisms underlying carcinogenesis and the intricacies of evolution of immune cells underlying malignancy and therapy resistance. Using complementary toolboxes ranging from immunocompetent murine models of these diseases, ex vivo and in vitro systems recapitulating the heterotypic communication between tumour and immune cells, patient samples and dataset analyses, we study the heterogeneity of immune cells in the course of tumour progression. The interests of our research can be summarized in the following points: 
  

  1. Uncovering the mechanistic bases of the coevolution occurring between cancer and immune cells that fuel cancer growth and can we therapeutically harness vulnerabilities in these interactions  
  1. Design novel, efficiently superior tools to rewire specific subsets of immune cells and improve current therapeutic approaches  

About Leila Akkari

My Research

Leila Akkari trained in cellular and molecular biology during a BA at the University of Montpellier in France, and graduated in 2004 before performing a Master in oncology and immunology between Montpellier and Manchester (England). She performed her PhD in health sciences at the Molecular Genetics Institute of Montpellier, CNRS, in HCV-driven liver cancer prior to joining Prof. Johanna Joyce's laboratory at Memorial Sloan Kettering Cancer Center in NYC as a post doc. During this time, she worked on mouse models of brain and pancreatic cancer, primarily focusing on tumor-associated macrophages and their pro-tumorigenic roles in multiple tumor microenvironment.

Since January 2017, Leila Akkari leads a research group at the Netherlands Cancer Institute in Amsterdam that is interested in the microenvironment-mediated mechanisms of tumor maintenance and therapeutic resistance to therapy in brain and liver malignancies. The main focus of her research is to understand and target the dynamic changes in the tumor microenvironment that are associated with cancer malignancy, with a particular interest in macrophages, a highly plastic and heterogenous immune cell type in solid cancers. Her lab uses a plethora of murine models of cancers to develop and test microenvironment- targeted drugs in a stage-dependent and population-dependent manner.
