Project title:
Pathogenesis of ASXL1mutated AML; deciphering mechanisms for novel rational interventions
This project aims to deepen our molecular understanding of ASXL1-mutated (ASXL1mut) acute myeloid leukemia (AML). ASXL1mut frequently occur in myeloid malignancies and, especially in AML, are accompanied by an unfavorable prognosis. By combining Asxl1mut with a genetic system randomly causing mutations, leukemia occurs in mice. After sequencing, Asxl1mut AML are compared to large-scale human ASXL1mut AML datasets, enabling the pinpointing of novel crucial events in leukemogenesis. The most promising identified cancer genes are then (pre)clinically validated for their therapeutic use, e.g., through the development of biomarkers or individualized targeted (combination) therapies.

Project Title: Unveiling interactions between senescent tumor cells and the host immune system - Implications for Senolytic Immunotherapy
Therapy-induced senescence (TIS) prevents tumor growth and improves treatment outcome in many preclinical cancer models. TIS also alters the tumor biology and environment, contributing to treatment resistance and tumor relapse. There is a close relationship between senescent tumors and the host immune system, but the molecular mechanism of their interaction remains unclear and contingent upon cancer type. Using spatial proteomic, biochemistry and molecular biology techniques, the aim of my project is to characterize the interactions between senescent tumor and the host immune system to identify new actionable moieties to improve the efficacy of senolytic immunotherapies in different cancers.

Project Title: Using DNA methylation profiling for differential diagnosis and for determining the origin of ovarian cancers
My research interests lie in classifying, solving differential diagnosis problems, and determining the origin of ovarian cancers. We are using DNA methylation data to develop machine learning algorithms for analyzing ovarian tumors. DNA methylation patterns are highly tissue specific, hence are an ideal method for performing differential diagnosis. Currently, we aim to develop a machine learning classifier that can differentiate subtypes of ovarian carcinomas. Additionally, we aim to use DNA methylation data to predict the outcome of and to subclassify ovarian carcinomas. We plan to expand our research to other female reproductive system tumors.

Project title: The Role of Radiotherapy in the Treatment of Atypical Meningiomas – A Methylome- and Genome-based Analysis.
The role of an adjuvant radiotherapy for grade 2 meningiomas remains unclear. The traditional approach of meningioma diagnosis using only light microscopy and immunohistochemistry to distinguish the current subclasses is prone to interobserver biases and limited regarding personalized treatment decision making. This knowledge gap is highlighted by contradictory findings in various studies. By implementing a DNA-methylation-based classifier and incorporating genetic risk factors to ensure accurate tumor subtype identification, the project aims to specifically assess the role of adjuvant radiotherapy in a homogenous meningioma cohort.

Project Title: Understanding and circumventing resistance to targeted immunotherapy in pediatric relapsed/refractory B-cell precursor acute lymphoblastic leukemia
Targeted immunotherapy, e.g. with the CD19-directed bispecific T-cell engager Blinatumomab or the CD22-directed toxin-conjugated monoclonal antibody Inotuzumab/Ozogamicin, has significantly improved the outcome of patients with pediatric r/r BCP-ALL. However, several resistance mechanisms have been observed. As a prerequisite for circumventing treatment failure, our research module aims at elucidating the underlying intrinsic or acquired resistance mechanisms. Furthermore, we investigate their relevance in clinical subgroups and try to identify predictors of response failure. We thereby hope to improve precision medicine concepts in upcoming clinical trials for pediatric r/r BCP-ALL.

Project Title: Functional relevance of DNA circularization and its contribution to genetic heterogeneity and evolution in childhood solid tumours
My work aims to assess changes in extrachromosomal circular DNA (ecDNA) heterogeneity over time using various cell types and sequencing techniques. Insights from these data will help determine how circular DNA elements are selected for and expressed in the context of enhanced proliferation. Understanding the nature and clinical importance of ecDNA is currently limited by our ability to reconstruct entire circles and genomic fragments contained therein. Hence, my project involves adaption and integration of existing methods, as well as development of new algorithms to reliably quantify and reconstruct ecDNA elements from bulk and single-cell sequencing data at clinically relevant time points.

My research interests lie in understanding and deciphering the molecular mechanisms underlying tumorigenesis and cause targeted and/or immune checkpoint inhibitor therapies to fail. Currently, we focus on biobanking for the purpose of comprehensive genomic tumor characterization and the implementation of liquid biopsy. Second, we study immune adverse events, especially in the skin, during immune checkpoint therapy to understand and compare the underlying molecular mechanism to inflammatory and autoimmune diseases of the skin. Third, we are interested in the different compartments of the immune system fighting cancer, particularly the role of the dendritic cells and the killing by granzymB.

Clonal hematopoiesis (CH) refers to the presence of mutant blood cell clones, a condition that is prevalent among the elderly population. Its significance extends to various clinical conditions, notably cardiovascular and malignant diseases. My project aims to explore the clinical and mechanistic implications of CH in CLL patients. Besides classical CH genes, I focus on mutations associated with targeted therapies, deciphering the behavior of the hematopoietic system under novel kinds of selection pressure. In addition to sequencing techniques, I employ CRISPR/Cas9 to create mutant CH model systems.

Project Title: Extrachromosomal MYCN amplification dynamics enable rapid adaptation to chemotherapy in neuroblastoma
Neuroblastoma commonly affects very young children. Despite their generally positive initial response to treatment, these tumors frequently recur with surprising resistance. This is especially puzzling since neuroblastomas typically show little genetic heterogeneity at diagnosis, pointing to unknown rapid adaptation mechanisms. By utilizing bulk and single-cell sequencing, as well as spatial proteomics analyses, we've found that extrachromosomal DNA (ecDNA)-driven genetic heterogeneity leads to variations in treatment response among cells containing MYCN amplification. This insight may explain why high-risk neuroblastomas can rapidly recur after initial treatment success.

Protein ubiquitination is a post-translational modification that leads to proteasomal degradation or altered function of a protein. My project aims to investigate the oncogenic role of deubuquitinating enzymes (DUBs) and their exploitation as drug targets in Acute Myeloid Leukemia (AML). Our preliminary CRISPR screenings for DUB inactivation identified USP7 to be essential for several AML cell lines. A combinatorial approach encompassing proteomic, biochemistry and molecular biology analyses will aim to identify novel the substrates of USP7 which are critical for AML. The results of this project will help to further understand the role of the ubiquitin-proteasome system in the pathogenesis of AML and to identify new therapeutic approaches.

Project Title: Genetic Characterization of Primary Mediastinal B cell Lymphoma
Unravelling genetic aberrations underlying PMBL lymphomagenesis has the potential to identify new targets for tailored therapy approaches. A thorough description of the mutational spectrum in PMBL and the identification of key oncogenic drivers will thus facilitate rational therapeutic approaches. Until now, we have collected the world’s largest PMBL cohort (n>400) through national and international collaborations comprising clinically well annotated patients. Using a combination of whole-exome, targeted deep resequencing and gene expression analysis, we aim to identify key oncogenic drivers and deregulated signaling pathways in PMBL. Based on the previous molecular analyses, functional consequences of candidate driver mutations will be analyzed in PMBL cell lines using the CRISPR/Cas technology.

Wat can we learn about disease from the healthy? To answer this question, in my current research project I focus on the molecular analysis of normal and diseased human tissues. Specifically, we analyze DNA-sequencing data from normal, precancerous, and cancerous tissues to analyze and compare mutational processes in the different stages of tumorigenesis. With this approach we aim to characterize different paths of tumorigenesis and identify yet unknown molecular tissues of origin of different cancer types.

Project title: Breaking Radioresistance of Soft Tissue Sarcomas by New Combination Therapies: Development of a Preclinical Pipeline
Despite their radioresistance and heterogeneity of over 70 subtypes, all soft tissue sarcomas (STS) are treated with the same perioperative radiotherapy regimen. Preclinical and clinical data on effective combination therapies of radiation and targeted compounds is scarce. This proof-of-concept study uses preclinical 3D models of STS to test two hypotheses: 1) Differences in radioresistance among STS subtypes can be reproducibly shown in 3D STS models; 2) New combination therapies of radiation + targeted compounds can overcome radioresistance in STS and be demonstrated in 3D STS models. The study lays the foundation for a preclinical drug and radiation screening platform for STS.

Project Title: Unraveling interplay between MYCN and cellular components in the immunosuppressive high-risk
neuroblastoma microenvironment to enhance immunotherapy success
Half of high-risk neuroblastomas harbor amplifications of the MYCN oncogene, a key player in progression and metastasis and correlating with poor prognosis in pediatric patients. Chimeric antigen receptor (CAR) T cells offer a new approach against high-risk neuroblastoma. However, tumorassociated macrophages and cancer-associated fibroblasts, contribute with intertwined function to the immunosuppressive microenvironment, thus impeding CAR T cell efficacy. My research aims to uncover how oncogenic MYCN levels influence the presence, behavior, and function of macrophages and fibroblasts in the neuroblastoma microenvironment and how these components in turn hinder CAR T cell success.

Project title: Characterizing the role of MACC1, a causal driver of cancer metastasis, in immune evasion
Metastasis accounts for >90% of cancer deaths. To improve patient outcomes, identifying (targetable) causal drivers of metastasis is essential. MACC1 acts as such a driver in more than 20 cancer entities. One key prerequisite for metastasis is the evasion of immune responses. Whilst MACC1 is central for many hallmarks of cancer, its effect on immunological processes remains poorly understood. Using spatial proteomics, high-throughput data sets and animal models, we aim to characterize the role of MACC1 in caner immune evasion. Characterizing metastatic potential and anti-tumor immunity will also help to improve the understanding of intervention strategies, specifically immunotherapies.

Project Title: Characterization of the tumor microenvironment, cellular composition and molecular changes in CNS metastases and primary brain tumors of therapy naive and pre-treated patients
The primary objective of our study is to characterize the tumor immune microenvironment (TIME), cellular composition, and molecular changes in brain metastases (BrM). The research aims to understand the interactions between tumor cells and their surrounding environment, especially in patients who have undergone different treatments. The study hypothesizes that the composition of the tumor microenvironment can be altered by prior treatments but on the other hand can also assist predict response to future treatments such immunotherapy. Using scalable and spatial techniques like multiplex immunohistochemistry, MALDI imaging as well as gene expression analyzes the study will analyze tissue samples to identify therapy-associated changes.
Similarly, the project will employ an established pre-clinical ex vivo model using patient-derived explant cultures, which will facilitate experimental studies to define the functions of individual components of the tumor microenvironment. The ultimate goal is to identify potential resistance mechanisms to treatments and provide insights for future therapeutic strategies.

Project title: SIGN-OC (SIGNature for neoadjuvant chemotherapy in Ovarian Cancer)
The gold standard of care for ovarian cancer consists of chemotherapy and debulking surgery but the debate on optimal treatment sequence is still ongoing. In the phase III AGO-OVAR TRUST trial,746 patients were randomized into two treatment arms, comparing neoadjuvant chemotherapy followed by surgery vs. upfront surgery. Our goal within the SIGN-OC JF program is to analyze clinical samples obtained within the TRUST trial to study mutational signatures and predictive biomarkers of chemotherapy response with a custom designed panel of 232 genes, including frequent alterations in ovarian cancer, with emphasis on HRR- and PI3K/AKT/mTOR pathway associated genes.

Project title: Machine learning for risk stratification of liver cancer in real-world data
Hepatocellular carcinoma is a deadly malignancy, often diagnosed at late stages. Current screening is limited to patients with liver cirrhosis, despite a variety of risk factors being characterized. This poses a challenge in risk stratification. The goal of my project is to train machine learning models on real-world data from large-scale biobanks such as the UK Biobank (n=500.000), integrating physical, serum, genomic, and metabolomic data. Models will be built for several, clinically relevant scenarios, comparing added information per data modality. Once the external validation on several other biobanks is performed, the goal is to bring AI-based risk prediction into clinical studies.

Project title: Developing diagnostic and prognostic biomarkers for gastrointestinal cancers with AI-assisted image analysis
Artificial intelligence (AI) can process large amounts of data in a very short time, making it suitable for analyzing complex relationships beyond human capabilities. In precision oncology, this can be utilized to derive biological and prognostic information from oncological imaging data. Gastrointestinal tumors are of particular interest due to their high prevalence and biological heterogeneity. Colon and gastric adenocarcinomas in particular have a high incidence worldwide. Some patients exhibit differences in long-term survival despite similar initial disease stages, which is not tackled in clinical routine. AI has the potential to enhance existing strategies for prognostic stratification of patients with gastrointestinal tumors. In our project, we aim to identify prognostic information in clinical imaging data of colon and gastric adenocarcinoma patients across different time points and disease stages.

Project title: Modelling gastric cancer using stomach-specific inducible mouse models and patient

Gastric cancer (GC) is the third leading cause of cancer deaths. Due to missing early clinical signs, GC is diagnosed at late stage cancer with distant metastases, resulting in incurable disease. Therefore, I aim to shed light on the pathological mechanisms of GC metastasis. Additionally, I aim to investigate the tumorigenesis of gastric adenosquamous cancer (ASC) which is characterized by aggressive tumor progression. Since the pathogenesis of ASC is unknown, it is difficult to define treatment strategies.
Therefore, I plan to identify the mutational pattern and transcriptomic profile of ASC. For both projects, I will use stomach-specific mouse models and patient derived organoids.

Project title: Characterization of the antitumoral potential of human genome-modified macrophages
Cancer immunotherapy based on macrophages are hindered by a postmitotic phenotype and a proclivity for repolarization by tumor cells. Chimeric antigen receptor (CAR)-bearing macrophages have recently been shown to effectively eat away at tumor cells. Our work shows that genetic modification in the absence of specific CARs in macrophages maintains antitumoral effects which enables applicability in tumors that have no identifiable CAR target.
Our macrophages are denoted by a continuous expansion of terminally differentiated macrophages in vitro, thus potentially enabling cellular therapy. We are committed to delivering a cell therapy product able to outsmart solid tumors even in instances where conventional therapies have failed.

Project title: Beyond Traditional Methods: Leveraging Large Language Models to Unveil Hidden Gems in Oncology Data
The field of oncology heavily relies on the transfer of information between healthcare providers and researchers, a process often hampered by the unstructured nature of medical data. Key insights remain buried within free-text formats, eluding traditional quantitative analysis. Large Language Models (LLMs) present a solution to these longstanding challenges, surpassing classical natural language processing (NLP) techniques in both scope and depth. This project aims to employ LLMs to systematically decode and organize vast amounts of text data, which, due to time-consuming processing requirements, have been underutilized at scale for broader informational gains in oncology. The goal is to enhance oncological data management, facilitating a more scalable and efficient approach for information extraction that supports improvements in diagnosis and treatment strategies.

Project Title: cf-DNA and EVs as sources for biomarkers for early detection of second primary malignancies in patients with heritable retinoblastoma
Heritable retinoblastoma is a tumour predisposition syndrome caused by heterozygosity for pathogenic RB1 variants. Patients have a high risk to develop a second primary malignancy later in life. Development of such tumours is often initiated by loss of heterozygosity of the RB1 gene. The aim of our project is to develop a noninvasive blood test for the early detection of these secondary cancers. Therefore we investigate cfDNA released by tumour cells to detect the allelic imbalance at the RB1 gene locus. Using the SimSenSeq technology (Ståhlberg et al. 2017) we perform Next-Generation Sequencing to determine the allelic ratio with high sensitivity and specificity to reach the requirements of a diagnostic test.

Project Title: Translational theranostic applications in oncology
Theranostics stands as a cornerstone of personalized medicine, meticulously delving into specific target structures within tumors or their microenvironment to enable both diagnostic and therapeutic interventions. Within this cutting-edge domain, radiotheranostics integrates molecular imaging with targeted radionuclide therapy, offering an opportunity to selectively target and eliminate tumor cells while minimizing adverse effects. This approach holds promise for highly effective therapies with reduced toxicity, addressing concerns related to resistance.
My research primarily focuses on translational theranostic projects in a multidisciplinary and and comprehensive manner. On the one hand, i work on unravelling the intricate dynamics among FAP-expressing cells within tumors, cancer-associated fibroblasts (CAFs), and tumor cells, along with their interactions within the tumor microenvironment. This translational effort initially targets sarcomas, with the aim of extending to other tumor entities. Additionally, I aim to elucidate the role of SSTR2 in SCLC, investigating its correlation with immunohistochemistry and its impact on patient survival, with the utmost purpose of detecting patients eligible for theranostic approaches.

Project Title: Therapeutic modulation of glycosaminoglycan-chemokine interactions in cancer
Despite the significant success of the existing anticancer treatment options, the overall survival in various cancer types remains poor. One of the reasons of inefficiency of anticancer treatment is develpment of tumor resistance. It is partially mediated by expansion of exhausted and/or immunosuppressive immune cells in the tumor tissue and lymph nodes, which suppress the cytotoxic mechanisms and support the survival and metastasis.
Tumor microenvironment (soluble factors and cellular interactions) drive newly migrated immune cells into exhausted and/or immunosuppressive state. Glycosaminoglycans on endothelium and extracellular matrix bind the chemoattractants and provide the stable concentration gradient important for migration and activation of immune cells.
With this project, we aim to restore anti-tumor adaptive immune responses by targeting glycosaminoglycan-chemokine interactions.

Project Title: Cellular plasticity in pancreatic cancer – from phenotypical organoid screening to underlying biophysical mechanisms
Pancreatic cancer is notorious for its poor survival rates and remarkable resistance to available therapies. Early-passaged patient-derived tumor organoids (PDO) recapitulate tumor heterogeneity and have the potential for in vitro response prediction. However, widely utilized assays do not capture spatial heterogeneity and dynamics.
My research project focuses on temporally resolved, 3D imaging-based drug screenings of pancreatic cancer organoids to detect and characterize phenotypical and programmed cell death-related drug responses. Our aim is to incorporate these features to predict patient response in vitro and identify potential drug combinations to exploit cell state vulnerabilities. This translational project is complemented by a mechanistic project to study the role of collective cell mechanics in distinct phenotypes and clinical aggressiveness.
By integrating spatiotemporal information with mechanical properties, we hope to contribute to the utilization of PDO for clinical decision-making.

Project Title: Mechanisms of non-genetic resistance to Menin inhibitors in NPM1 mutant AML
The interaction between MLL1 and Menin proteins plays a crucial role in acute myeloid leukemias (AMLs) with MLL translocations (MLLr) or NPM1 mutations. Menin inhibitors disrupt this interaction, leading to reduced expression of leukemic genes and inducing differentiation in MLLr and NPM1mut AML. However, single-drug treatments often face limitations due to the development of drug resistance. To address this issue, we aimed to understand the molecular mechanisms underlying sensitivity and resistance to Menin-MLL1 inhibition in order to provide potential avenues for a promising and novel AML treatment.

Head and neck squamous cell carcinoma (HNSCC) are among the most common malignant neoplasms worldwide. While locally limited disease can be cured by surgery and/or radiochemotherapy, a multimodal and potentially side-effect rich therapy regimen is required for advanced HNSCC. The genetic heterogeneity and distinct aetiologies of HNSCC significantly complicates the therapy and makes an individualized therapeutic approach indispensable for a promising long-term treatment. Patient-derived tumor organoids (PDTOs) could provide a preclinincal model to test treatment responses in vitro.

Project Title: Disentangling tumor tissue specific regulatory mechanisms of prothrombin (proF2) gene expression by differential high-content screening in an integrated genetic reporter system
In this project, we are interested in developing a standardized methodology for systematically dissecting the tumor-specific disease entities and mechanism that promote extrahepatic proF2 involved in cancer progression using a transgenic reporter mouse model (Nourse et al., 2021). In a proof of concept, the suitability of this experimental setup to perceive hitherto unknown sources of detrimental extrahepatic proF2 has been confirmed (Nourse et al., 2021) which corresponds to findings from tumor patients (Xue et al., 2010). A broad direct in vivo RNAi screening (Wuestefeld et al., 2013) and counter validation in human patient’s samples is expected to unravel novel insights into disease relevant entities and pave the way for developing new therapeutic concepts.

Muscle-invasive bladder cancer (MIBC) is a heterogeneous disease with poor oncologic outcome. Six different molecular subtypes of bladder cancer have been identified by transcriptomic profiling. These classes differ regarding underlying oncogenic mechanisms, histology and clinical characteristics, including outcomes. But so far, no clinical translation and application of molecular subtypes has occurred. We aim to validate a robust method to define molecular subtypes in MIBC and to correlate these with histological subtypes, response to chemotherapy and survival-rates.

Project Title: Synonymous mutations driving clonal hematopoiesis in the context of cardiovascular and malignant diseases
Hematopoietic stem cells acquire somatic mutations in distinct driver genes leading to clonal hematopoiesis (CH), a state which frequently fades to hematologic malignancy. Besides, several studies revealed association of CH with chronic heart failure. Importantly, this was only investigated for amino acid-affecting mutations while synonymous mutations have been completely neglected despite their potential to alter RNA folding, stability, splicing or translational speed and pausing. Therefore, the primary objective of the project is the mechanistic elucidation of how synonymous mutations drive CH and subsequently cause cardiovascular and malignant diseases.

Our research focuses on the menin-MLL1 interaction, an epigenetic dependency in NPM1 mutated and MLL-rearranged leukemia. Menin-inhibitors have demonstrated promising in vitro and in vivo activity and are currently investigated in clinical trials. While immunotherapy has revolutionized the treatment of solid tumors and lymphatic neoplasms, it has been far less successful against AML. We are investigating if the use of selective epigenetic drugs like menin-inhibitors can augment the efficacy of immunotherapies in AML.

Project Title: Investigating the consequences and therapeutic vulnerabilities of KDM6A and KDM6C mutations in Urothelial carcinoma
KDM6A and KDM6C, tumor suppressor genes on the X and Y chromosomes, are frequently inactivated in male bladder cancer. This project investigates their roles in bladder carcinogenesis. KDM6A often undergoes inactivating mutations, while KDM6C is inactivated through Y chromosome loss. These genes will be knocked in bladder cancer cells, followed by phenotypic assessment including proliferation, migration, invasion, as well as changes in chromatin modifications and protein interactions. Finally, utilizing chemical screening, we will identify synthetic lethalities with
gene loss, in hope of elucidation their role for potential therapies.

Project Title: Development and translation of novel theranostic hybrid molecules for pre-, intra-, and postoperative diagnosis and therapy of cancer
Our research is focusing on identifying new biomarkers for the classification of tumors, assessing metastasizing potential and monitoring therapy. In particular my group is working on the development of small molecule peptides with a strong focus on hybrid molecules suitable for preoperative imaging, intraoperative navigation as well as for targeted endoradiotherapy of different cancer types. Therefore, we are using innovative biological, biotechnological and chemical approaches to identify novel peptides to a variety of clinically relevant target structures. Our development pipeline comprises the identification of potential binders, their detailed preclinical characterization including imaging studies finally leading to clinical translation.

Project Title: In-depth proteogenomics of solid tumors to expand and complement routine molecular diagnostics and support personalized therapeutical strategies
Proteogenomics describes the integration of proteomics to multi-omics studies that integrate DNARNA-, and protein-level omics-data. In my research I apply in-depth proteogenomics on solid tumors
to address two different aspects:
a) Corroboration of determined sequence variants (DNA or RNA-level) on the proteome level; an approach which may also yield information on the proteomic penetrance of said variants. Results may aid in prioritization of potential treatment schemes if there is co-occurrence of multiple variants with clinical implications.
b) Determine the impact of genomic aberrations on oncogenic signaling pathways; many genomic aberrations are linked to oncogenic signaling and proteomic approaches enable corroborative, direct probing of this impact.

My junior research group “MALDI imaging” investigates tumor tissue cohorts and organotypic tissue slice cultures by MALDI mass spectrometry imaging and complementary omics and imaging modalities. MALDI imaging derives hundreds of molecular distribution maps directly from thin tissue slices. We apply MALDI imaging of metabolites and peptides to investigate spatially resolved tumor biology and to derive spatio-molecular signatures with diagnostic and prognostic potential. Furthermore, we establish open-source analysis tools and workflows in the Galaxy platform and work towards standardization and reproducibility of MALDI imaging, which lays the foundation for future clinical applications.

Project Titel: Systematic analysis of nonstop extension mutations in high throughput
Research in our group has shown that nonstop mutations are associated with cancer and are known to have a functional impact on protein expression and function. Our group has created the database NonStopDB, a comprehensive set of nonstop mutations in human cancer. In this project we aim to systematically analyse the functional impact of all non-stop extension mutations found somatically in human cancer in a pooled format using reporters and next generation sequencing.

Project title: Deciphering Menin-MLL inhibitors to better target MLL/KMT2A-rearranged leukemia via combinatorial genetic and epigenetic targeting approaches.
Targeting protein-protein interactions (PPIs) with small-molecule inhibitors has become a hotbed of modern drug development. In this project, we investigate effect of PPI inhibitors that block Menin from binding to MLL proteins. Menin acts as an essential cofactor for MLL/KMT2A-rearranged leukemia. Menin-MLL inhibitors have recently entered phase I/II clinical trials for treating MLL/KMT2A translocated or NPM1 mutant leukemia. Understanding the complete mechanism of action of Menin-MLL inhibitors as well as developing novel epigenetic/ genetic combinatorial treatment strategies to better eradicate MLL-rearranged leukemia are main objectives of the project.

Project Title: The immune environment of acute myeloid leukemia
Acute myeloid leukemia (AML) is the most common hematologic malignancy in adults. It is characterized by poor outcome with an overall 5-year-survival of only 50% in young patients and 20% in elderly patients. As the curative potential of allogeneic hematopoietic stem cell transplantation is dependent on immunotherapeutic effects (graft-versus-leukemia effects), immune evasion seems to play a pivotal role in the pathogenesis of AML. A comprehensive research program using highdimensional single cell cytometry combined with bioinformatic analyses represents a powerful tool to gain deep and unbiased insights into the immune signatures of AML patients. Immune patterns that predict response may be integrated into the stratification of AML, particularly in the absence of predictive genetic markers. To verify the impact of the identified signatures, detailed functional analyses of patient mononuclear cells will be performed in vitro to investigate the effect of cell-intrinsic and -extrinsic alterations on anti-AML immunity. The ultimate goal is to identify novel stratifying biomarkers and/or therapeutic targets to overcome immune evasion of AML cells and achieve improved patient outcome.

Project Title: Discovering non-canonical driver mutations in cancer in high-throughput using endogenous models
Most point mutations found in cancer are functionally uncharacterized and hence cannot be exploited for patient stratification and therapy decisions. Current approaches to study mutations endogenously are time-consuming and lack the possibility for high-throughput. In this project, we focus on the introduction of comprehensive libraries of targeted mutations endogenously into the cell genome using innovative CRISPR-derived tools to assess their functional impact and their impact on therapy response and resistance.

Project Title: Characterization and Molecular Targeting of Patient-derived Organoids
This project aims at achieving a comprehensive understanding of pancreatic ductal adenocarcinoma (PDAC) at both the single-cell level and through patient-derived organoids. To deconvolute the heterogeneity of the tumor and its microenvironment, single-cell RNA sequencing will be performed on biopsy samples from primary PDAC patients. In parallel, these biopsies will be used to establish patient-derived organoids (PDOs), which can be used as a model system to predict patient response to chemotherapeutic agents and targeted therapies. The rapid development of chemoresistance poses a substantial challenge in the treatment of PDAC patients. To address this, we plan to continuously expose PDOs to sub-lethal doses of chemotherapeutic drugs over an extended period to induce chemoresistance in vitro. Through a multi-omics approach, including whole genome sequencing (WGS), RNA sequencing, and metabolomics, we aim to identify the molecular mechanisms driving chemoresistance, providing potential targets for overcoming resistance.

Project Title: Genotypic and phenotypic characterization of patient-derived melanoma cell lines
Based on a transcriptome analysis, the aim of this project is to characterize the phenotypic properties of the four individual malignant melanoma cell lines, such as cell survival, proliferation, migration, and invasion. Furthermore, we are studying the underlying mechanisms, which effectuate the phenotype of the melanoma cell lines. Therein, we mainly focus on the MAPK/ERK or PI3K pathways, components of which are frequently mutated and thus are often constitutively active in cancer cells, driving their development and enhanced survival.
Project Title: Identification of early detection markers in pancreatic ductal adenocarcinoma (PDAC)
The aim of this project is to establish an early genetic classifier of PDAC based on a meta-analysis of independent studies. In combination with system biology and bioinformatics approaches, it is our aim to identify early markers of PDAC in patient-derived samples (eg. liquid biopsies). This may allow the differentiation of PDAC from early pancreatic intraepithelial neoplasia (PanIN), pancreatitis, and healthy tissues. In a parallel approach, we seek to inactivate the classifier genes in established PDAC cell lines and to assess the effects of the inactivation on the functionality of these cells.

Patient-derived in vitro models present a promising platform to predict the efficacy of different radiation modalities, including types and dosages, thus promoting personalized treatment planning in radiation oncology. Our aim is to tailor radiation treatment to the preserved tumor biology of individual patients, making it amenable to in-depth analyses. This approach may improve our molecular understanding of how radiation affects brain cancer cells through a comprehensive multi-omic approach and ultimately improve radiation effectiveness while mitigating side effects by optimizing radiation protocols.

The 2021 update of the WHO classification of central nervous system tumors has integrated comprehensive molecular findings into the diagnostic workflow, enabling a more accurate diagnostic process and risk assessment. Novel radiotherapeutic modalities using protons or carbon ions represent an auspicious therapeutic concept with an increased accuracy in dose delivery - while reducing the radiation dose for the surrounding organs at risk. Post-hoc integrated molecular-morphological scoring will identify patients at risk of progression, where proton- or carbon ion radiotherapy may be particularly beneficial, facilitating the path to a molecularly-guided treatment in patients with brain tumors.

Project Title: Novel strategies to analyze the role of Wnt-signaling in cancer
Deciphering the crosstalk of tumor cells and their surrounding stroma during cancer progression and metastasis is of highest importance to further optimize therapeutic strategies and prevent late recurrence. Wnt signaling governs cell faith and tissue polarity during development and aging. It was found dysregulated in various pathological processes and diseases such as cancer. This project aims to get further mechanistic insights into the complex Wnt-signaling networks using genome engineering and advanced imaging techniques that could lead to the identification of targets for earlier diagnostics and therapeutic intervention.

Project Title: Alterations of fatty acid metabolism and pharmacological counteraction in ZBTB7A deficient leukemia
ZBTB7A is a transcription factor frequently mutated in acute myeloid leukemia (AML) patients with t(8;21) translocation (which results in the RUNX1-RUNX1T1 fusion protein). We use CRISPR-Cas9 to knockout ZBTB7A and mimic these loss-of-function mutations in order to study ZBTB7A effect in metabolism. Our ultimate goal is to find metabolic drug targets for therapy. For that, we perform metabolic tracing by mass spec, metabolic flux assays, and treatment with several metabolic inhibitors. Besides, since ZBTB7A prevents RUNX1-RUNX1T1-mediated clonal expansion in vitro, we are interested in investigating the cooperation of ZBTB7A knockout and RUNX1-RUNX1T1 during leukemogenesis in a mouse model.

Project Title: Tumour evolution and immune microenvironment dynamics in response to neoadjuvant treatment in oesophagael adenocarcinoma
Patients with locally advanced oesophageal cancer (OAC) are treated with surgical resection and neoadjuvant chemotherapy or radiochemotherapy. However, 50% to 60% of tumours are resistant to neoadjuvant therapy, leading to an overall poor outcome with a 5-year survival of 12.6%. The ecological and evolutionary dynamics responsible for treatment failure are incompletely understood. In my research I perform a multi-omics study (whole exome sequencing, RNA-sequencing, T-cell receptor sequencing and image mass cytometry) with a multi-timepoint strategy to examine treatment response at clonal resolution and to investigate genetic and transcriptomic changes induced by neoadjuvant therapy in OAC patients. This project will provide fundamental insights into clonal dynamics, transcriptomic changes and dynamics of the microenvironment in response to neoadjuvant treatment in OAC patients, in order to provide fundamental insights into treatment response on the molecular level.

Project title: Metabolic features of high-risk multiple myeloma
The risk of progression and the response to therapy in multiple myeloma are determined by genomic risk factors including deletion of the tumor suppressor p53. Importantly, p53 is known to profoundly impact cellular metabolism. In our project, we will characterize the metabolic landscape of high-risk myeloma in cell line models and primary patient samples through metabolomic analyzes. We furthermore aim to identify underlying mechanisms and metabolite mediated effects on the tumor environment by employing transcriptomic technologies and functional assays. Ultimately our goal is to identify resistance mechanisms to established drugs and to discover novel therapeutic targets in multiple myeloma.

Project Title: Identification of tumor-antigen specific T cell receptors for the treatment of
pediatric cancers.
Despite significant survival improvements, cancer ranges among the leading causes of deaths in children and young adults. Immunotherapy including adoptive T cell transfer emerges as promising therapeutic strategy in pediatric hematological and solid malignancies.
The short- and mid-term goals of the project are to identify and characterize T cell receptors (TCRs) in vitro and in preclinical models targeting overexpressed and shared antigens in pediatric cancers. The aim is to provide data for efficacy and safety of selected TCRs for further evaluation in phase I clinical trials.

Project Title: Spatial transcriptomic-based dissection of tumor-infiltrating
lymphocytes (TIL) for the improvement of immunotherapies and cellular therapies in pancreatic cancer
The field of artificial intelligence is rapidly expanding, providing novel insights into tumor biology. Single-cell RNA-sequencing (scRNA-Seq) for example can provide information of cell-to-cell interactions at an unforeseen resolution. However, one fundamental limitation of scRNA-seq is the loss of spatial information, which is known to influence prognosis and treatment response of certain cancers. Building on our previous successful investigations, we hypothesize that we can leverage spatially-resolved gene expression profiling to identify pivotal signaling pathways in tumor-infiltrating lymphocytes (TIL) and exploit these pathways for engineering of next-generation cellular therapies.

Project Title: OXPHOS-Dependent Radiosensitization of Patient-Derived Pancreatic Cancer Organoids
Pancreatic ductal adenocarcinoma is a highly lethal entity with poor prognosis. Neoadjuvant chemoradiotherapy aims to achieve resectability, but intrinsic radioresistance and hypoxia hinder therapeutical success. This project investigates whether inhibiting oxidative phosphorylation (OXPHOS) can enhance radiosensitivity by increasing intracellular oxygen levels. For a translational approach we are using patient-derived organoids, to assess the efficacy of OXPHOS inhibitors combined with radiation. We employ a range of techniques, including immunohistochemistry, cell viability assays, 3D fluorescence microscopy and RNA sequencing to characterize radiation response.

Mucosal-associated Innate T (MAIT) cells are highly enriched in healthy liver but depleted in hepatocellular carcinoma (HCC), which prevents them from executing their potential antitumor functions. My research aims to elucidate how MAIT cells are routed towards tissues and which factors determine their adaptation to tissue microenvironments. Understanding the factors contributing to a tissue-resident MAIT cell phenotype could lead to an improvement in their anti-cancer functions. Moreover, I am interested in establishing MAIT-based cell therapies against solid tumors by taking advantage of their innate-like tumor killing capabilities and absence of HLA restriction.

Project Title: Leveraging omics data for AML prognostication and prediction of therapeutic outcomes
Acute Myeloid Leukemias (AML) are malignancies affecting myeloid hematopoietic stem cells. The prognosis depends on underlying genomic, transcriptomic and epigenomic aberrations. Historically, genetic data have been leveraged to predict survival. Today, a much larger wealth of available data combined with the introduction of multiple new drug classes makes both the prediction of therapeutic outcomes and a data-based selection of the best possible therapy more complex. We aim to integrate multi-omic data from large cohorts of AML patients to better predict outcomes and aid therapeutic decision-making.

Project Title: DKTK Organoid Platform; Droplet Microfluidics for PDO Culture
In Prof. Reichert’s group I am co-coordinating the establishment of the DKTK Organoid Platform with its first two use cases, NeoMatch and MetPredict. Both are prospective multicenter pilot trials: NeoMatch aims to confirm the ability of pancreatic cancer patient-derived organoids (PDOs) in forecasting response to neoadjuvant chemotherapy, and MetPredict the ability of colorectal cancer liver metastasis patient-derived organoids (CRC LM PDOs) in forecasting liver metastasis recurrence, respectively. Additionally, I am building a microfluidic workflow and aim to demonstrate its effectiveness in improving our current pipeline for generating PDOs of pancreatic ductal adenocarcinoma. Ultimately, this work will result in a better understanding of tumor heterogeneity and plasticity, as well as the interplay with the tumor microenvironment – major obstacles in successful treatment of PDAC, which to this day has a low 5-year-survival rate, despite our best efforts and recent advances. Moreover, breakthroughs relating to PDO model systems would most certainly be translatable to precision medicine applications with an even more direct impact on patients.

The immune system protects the organism from infections, but also from the development of malignant tumors. Adaptive immune cells are well-known to control tumor initiation, progression, and metastasis formation in various cancer entities. During the last years, myeloid immune cells have additionally been recognized as essential players in these processes. The mechanisms underlying the trafficking of these immune cells to malignant lesions, however, remain largely unclear. Hence, the aim of our translational project is to characterize the mechanisms of myeloid leukocyte trafficking to malignant tumors to identify novel therapeutic targets for innovative immuno-oncological treatment strategies.

Project Title: Validate and improve the treatment effects of CAR T cells against brain metastases from lung
cancer
Lung carcinoma represents the primary contributor to global cancer-related fatalities, 50% of
patients develop brain metastases throughout disease progression. The median survival time
of patients with brain metastases accepting current treatment strategies is < 12 months. CAR
T cells emerged as a powerful treatment for hematological malignancies, however, the
treatment effect of CAR T cells against solid tumor is limited, especially in brain tumors. To
uncover the underlying mechanisms leading to its failure, we established a syngeneic
orthotopic immunocompetent brain metastasis model in mice by combining a chronic cranial
window with repetitive intracerebral two-photon laser scanning-microscopy. This approach
enabled the in vivo-characterization of anti-tumor effects of fluorescent CAR T-cells and
cerebral lung cancer metastasis on a single-cell level over weeks, including the migration,
infiltration and persistence of CAR T cells inside tumor area, and interaction between CAR T
cells and tumor cells or tumor associated macrophages/microglia. With the expertise in
neurosurgery, coupled with the experience of mouse model in the field of cellular
immunotherapy, continues our research in the field of CAR T treatment for brain malignancies,
furthermore, we are establishing a mouse model to dissect neurotoxic side effects during CAR
T cell treatment.
