What if science could be summed up in 280 characters?

Of course it can’t – but it’sworth a try. In this section, we’ve summarised all the projects approved in 2025 in 280 characters: light-hearted, direct, in the style of the old Twitter. The result isn’t a collection of abstracts, but a series of snapshots. A cross-section of contemporary cancer research – 60 projects, reduced to the essentials.

Dr. Anna Brichkina  

@Marburg Philipps-University

Tumour-associated macrophages suppress the immune system and shield lung tumours. We are developing encapsulated active substances that specifically target these immunosuppressive cells – thereby paving the way for more effective
immunotherapies.

#LungCancer

PD Dr. Katrin Böttcher

@Tübingen University Hospital

Non-alcoholic fatty liver disease significantly increases the risk of liver cancer. We are investigating how specific fatty acids impair the anti-tumour function of MAIT cells – and thereby weaken the immune system of this metabolically stressed organ.

#LiverCancer

Dr. Martina Lutz

@Eberhard Karls University of Tübingen

PD-L1 checkpoint inhibitors act systemically – with a corresponding side-effect profile. We are developing bispecific antibodies that restrict PD-L1 blockade to the tumour microenvironment: more effective immunotherapy with reduced collateral damage.

#Immunooncology

Dr. Jan Böttcher 

@Eberhard Karls University of Tübingen

NK cells recognise tumour cells directly – but the tumour microenvironment blocks them via PGE2-EP2/EP4 signalling. We inhibit this dysfunctional mechanism in order to restore the efficacy of adoptive NK cell therapies.

#Immunotherapy

Prof. Sonia Tugues Solsona 

@Zürich University

The liver is the preferred site for colorectal cancer metastases. We are looking for memory T cells that continue to target tumours over the long term – as prognostic markers and a potential basis for new immunotherapies for colorectal liver metastases

#Metastasis

Prof. Dr. Thomas Dobner

@ Leibniz Institute for Virology, Hamburg

Human adenoviruses can transform cells – via the oncoprotein E1B-55K, which dysregulates cellular transcription factors such as TEAD. We are unravelling this mechanism at the molecular level and searching for new targets for cancer therapies

#virotherapy

Prof. Dr. Duncan Odom

@German Cancer Research Centre

Men are twice as likely to develop liver cancer as women – a fact with a biological mechanism that is still poorly understood. We are investigating the influence of sex hormones and sex chromosomes on hepatocellular carcinoma, in a mouse model and in humans.

#LiverCancer

Prof. Dr. Kai Breuhahn 

@Heidelberg University Hospital

YAP/TAZ-TEAD inhibitors show promise in the treatment of liver cancer – but tumour cells reorganise their transcription factor complexes and circumvent the treatment. We are analysing these resistance mechanisms and searching for more effective
combination strategies.

#LiverCancer

Dr. Wilhelm Palm 

@German Cancer Research Centre

Pancreatic cancer resists almost every form of treatment. We have discovered that tRNA wobble enzymes make tumour cells resistant to the growth inhibito mTORC1 and are investigating whether this mechanism can be targeted therapeutically.

#PancreaticCancer

PD Dr. Bülent Polat

@Würzburg University Hospital

In the case of rectal cancer, radiotherapy is set to become even more effective. By combining it with HDM2 and BH3 inhibitors, we aim to specifically activate the p53 signalling pathway and reliably induce apoptosis in tumour cells with intact p53.

#Radiotherapy

Dr. Linda Hammerich

@Charité – Berlin University Hospital

Two-thirds of patients with gastroenteropancreatic neuroendocrine tumours do not respond to peptide receptor radionuclide therapy. We are investigating how this treatment modulates the immune system – and using these findings to develop new
biomarkers.

#Endocrinology

David Ghasemi

@Hamburg-Eppendorf University Hospital

SHH-activated medulloblastomas are molecularly similar –yet their clinical courses are very different: curable in one case, fatal in the other. We are analysing differentiation barriers in the aggressive cases to explain the cause of these differences in prognosis.

#Neurooncology

PD Dr. Heiko Bruns 

@Erlangen University Hospital

Multiple myeloma remains incurable for many patients, despite modern treatments. We are unravelling how tumour-associated macrophages sabotage antibody-mediated phagocytosis – and are looking for strategies to overcome this block.

#MultipleMyeloma

Prof. Dr. Oliver Jäkel 

@German Cancer Research Centre

Radiotherapy for lung cancer carries a risk of pneumotoxicity. We are training convolutional neural networks to identify individual risk factors – and aim to use this to predict toxicity more accurately than previous clinical models have been able to.

#LungCancer

PD Dr. Anna-Luisa Luger 

@Frankfurt University Hospital

Targeted therapies against RTKPI3K- AKT signalling fail clinically in glioblastoma, even though the target structures are present. We are testing a library of specific kinase inhibitors on patient-derived tumour organoids in the tumour microenvironment.

#Glioblastoma

Dr. Dr. Varun Venkataramani 

@Heidelberg University Hospital

Glioblastoma cells form connections with oligodendrocytes via gap junctions – and utilise these connections to develop resistance to treatment. We are investigating this intercellular communication as a therapeutic target that has received little attention to date.

#Glioblastoma

PD Dr. Iurii Tolkach 

@Cologne University Hospital

The grading of prostate cancer remains subjective and prone to error today. We are developing AI-based analysis tools for digital histological slides, which enable a more objective assessment of tumour aggressiveness and clinical progression.

#ProstateCancer

Prof. Dr. Kyeong-Hee Lee 

@Hannover Medical School

A disrupted microbiota is a key factor in inflammation-associated colorectal cancer. We are identifying IgA antibodies from innate B-cell subpopulations that modulate the gut microbiome – and are evaluating their therapeutic potential in IBD-related cancer.

#ColorectalCancer

PD Dr. Sebastian Ziegelmayer

@The Entrepreneurial University Munich

Thickening of the colon wall on CT scans is common – and the cause is often unclear. Our multi-task deep learning framework automatically detects and characterises these findings and helps to distinguish between malignant and benign pathologies more reliably.

#Radiology

Prof. Dr. Günter Niegisch 

@Düsseldorf University Hospital

PARP inhibitors have so far had little effect on urothelial carcinoma. We are combining them with BET inhibitors to induce a BRCAness-like DNA repair deficiency in tumour cells – thereby making them responsive to this class of therapy for the first time.

#Urology

Prof. Dr. Lothar Dieterich

@Mannheim University Medical Centre

Tumours send extracellular vesicles to draining lymph nodes – and there prepare the pre-metastatic niche. We are investigating, using melanoma as a model, how these vesicles reprogramme lymphatic endothelial cells and macrophages for immune evasion.

#Lymphnodes

Prof. Dr. Oliver Brüstle 

@Bonn University Hospital

ZFTA-RELA fusion ependymomas are rare, have a poor prognosis and are difficult to model. We are establishing the first human iPSC-based disease modeland using it for a high-throughput drug screen in the search for new treatment options.

#Neurooncology

Prof. Dr. Sabine Werner 

@ETH Zurich

Tumour cells transfer mitochondria to cancer-associated fibroblasts – thereby altering the tumour microenvironment of skin cancer. We are unravelling the mechanisms of this intercellular transfer and investigating whether it can be blocked for therapeutic purposes.

#SkinCancer

Prof. Dr. Ferenc Krausz

@Ludwig Maximilian University of Munich

A blood test that detects cancer in several organs at the same time – even before symptoms appear? Using infrared laser technology, we analyse molecular fingerprints in blood plasma. The aim: early cancer detection via high-throughput diagnostics.

#EarlyDetection

Dr. Henry Fechner

@Berlin University of Technology

The oncolytic Coxsackievirus B3 attacks and destroys bowel cancer cells, whilst leaving healthy tissue unharmed. We are developing synthetic viral RNA based on an optimised variant, in order to advance this immunotherapy approach for clinical application.

#Virotherapy

PD Dr. Katja Breitkopf-Heinlein 

@Tübingen University Hospital

Non-alcoholic fatty liver disease significantly increases the risk of liver cancer. We are investigating how specific fatty acids impair the anti-tumour function of MAIT cells – and thereby weaken the immune system of this metabolically stressed organ.

#LiverCancer

Dr. Bodo Linz

@Friedrich-Alexander University of Erlangen-Nuremberg

Helicobacter pylori is a trigger for gastric cancer – but what happens in the tumour stroma afterwards? We are investigating how the microbiota and immune cells interact in various histological subtypes of gastric adenocarcinoma and influence tumour progression.

#GastricCancer

Dr. Wibke Bayer 

@Essen University Hospital

Not all macrophages are the same – and which subpopulation dominates in the tissue has a significant influence on how well leukaemia viruses are kept under control. We are investigating these population dynamics and their effects on the adaptive immune response.

#Leukaemia

PD Dr. Lars Schiffmann 

@Cologne University Hospital

Tumour blood vessels require considerable amounts of energy for growth and branching. We show that this metabolic demand is met by mitochondrial activity – and investigate whether this energy metabolism can be used as a therapeutic target.

#Metabolism

Prof. Dr. Anna Dubrovska  

@Helmholtz Centre Dresden-Rossendorf

HPV-negative head and neck tumours resist chemoradiotherapy and show little immune response. We are investigating how CD98hc reprogrammes tumour cell metabolism and inhibits anti-tumour immunity – and whether this pathway is therapeutically vulnerable.

#HeadAndNeckTumours

Dr. André Pfob 

@Heidelberg University Hospital

Unclear breast findings often lead to unnecessary biopsies. We are developing an intelligent, multimodal elastography system that combines tissue stiffness with AI analysis – for more precise differentiation and less invasive investigations.

#AIandMedicine

Prof. Dr. Mark Rubin 

@University of Bern

Anti-hormone therapy for prostate cancer drives tumour cells into lineage plasticity – they change their identity in order to evade the therapy. We are investigating chromatin remodelling mechanisms that regulate this plasticity as new target structures.

#ProstateCancer

Prof. Dr. Dr. Roland Ullrich 

@Cologne University Hospital

Small-cell lung cancer metastasises early and aggressively. In our analyses, metastases lose MHCI – an indication of active immune evasion. We are investigating the mechanisms behind this and looking for targets for immunotherapy strategies.

#LungCancer

Prof. Dr. Georg Lenz 

@University of Münster

One third of patients with diffuse large B-cell lymphoma do not respond to standard treatment. We are investigating the role of the AP-1 factor BATF in the molecular pathogenesis of various DLBCL subtypes as a potential therapeutic target.

#Haematology

PD Dr. Lisa Adams 

@The Entrepreneurial University Munich

CT, MRI and radiology findings combined in a single AI model: We are developing a multimodal foundation model that uses contrastive learning to generate generalisable tumour representations – across different organs and without the need for retraining.

#AIandMedicine

Prof. Dr. Christian Karger 

@German Cancer Research Centre

Carbon ions, protons or photons: How does each type of radiation affect prostate tumour cells? We are carrying out a comprehensive proteome analysis on 220 tissue samples and deciphering radiation-type-specific molecular signatures and resistance mechanisms.

#Radiotherapy

Prof. Dr. Dr. Christoph Schell

@Albert Ludwig University of Freiburg

The tumour microenvironment in muscle-invasive bladder cancer determines the response to immunotherapy. We are creating a molecular map of the tumour-associated matrixome – to predict who will benefit from checkpoint inhibitors.

#Urology

Dr. Anne-Marlen Ada  

@Carl Gustav Carus University Hospital, Dresden

Chromosomal instability occurs in 60–80 % of all carcinomas – and is particularly pronounced in gastric carcinoma. We model CIN in the laboratory to address the resulting growth advantages, immune evasion and metastatic potential from a
therapeutic perspective.

#Gastroenterology

PD Dr. Maike Buchner

@The Entrepreneurial University Munich

In chronic lymphocytic leukaemia checkpoint inhibitors and CAR-T cells, which are effective in other lymphomas, fail. We are investigating DUSP1/6 inhibition as a strategy to overcome the tumour’s own immunosuppression in CLL.

#Haematology

Pietro Crivello, PhD

@Essen University Hospital

T-cell alloreactivity against mismatched HLA is crucial for leukaemia control following stem cell transplantation. We use divergences in the HLA class III immunopeptidome to activate T cells specifically against leukaemia cells.

#Haematology

Dr. Ilona Hagelstein

@Tübingen University Hospital

T cells targeting lymphomas require two activation signals – TCR/ CD3 and co-stimulation via CD28. We are developing trispecific antibodies that modulate both signals in a tumourrestricted manner: precise immunotherapy rather than systemic T-cell activation.

#Immunotherapy

Dr. Angela Riedel 

@Julius Maximilian University of Würzburg

Recurrence is a clinically significant problem in hormone-receptor-positive breast cancer. We use patients’ own tumour organoids to determine the effectiveness of CDK4/6 inhibitors in the early stages – to inform more personalised treatment decisions.

#breastcancer

Dr. Dr. Raphael Johannes Morscher 

@University of Zurich

Neuroblastomas arise due to a block in cell differentiation – associated with a disrupted lipid metabolism. We specifically intervene in this lipid metabolism to force cancer cells to differentiate and halt their growth.

#PaediatricOncology

Prof. Dr. Volker Ellenrieder  

@Göttingen University Hospital

KRAS is mutated in 90 % of pancreatic cancers – and was long considered untreatable. New mutation-specific inhibitors are now available, but tumour cells adapt their metabolism accordingly. We are unravelling these transcription-induced resistance
adaptations.

#PancreaticCancer

Prof. Dr. Claudia Günther  

@Erlangen University Hospital

Genotoxic E. coli strains containing the pks operon are linked to the development of colorectal cancer. We are investigating how extracellular vesicles from these bacteria damage intestinal epithelial cells and what role the microbiome plays in carcinogenesis.

#ColorectalCancer

Prof. Martin Müller 

@German Cancer Research Centre

HPV vaccines based on virus-like particles offer only limited cross-protection. We combine structural biology with AI to design bespoke protein vaccines that provide broader protection and can be produced more cost-effectively.

#Vaccine

Prof. Dr. Dr. Ghazaleh Tabatabai  

@University of Tübingen

Meningiomas are the most common intracranial primary tumours – some progress despite resection and radiotherapy. We use DNA hypermethylation signatures as a molecular fingerprint to develop new targeted therapeutic strategies.

#Neurooncology

Prof. Dr. Barbara Walch-Rückheim

@Augsburg University Hospital

Cancer treatments have a lasting effect on the immune system – though not always for the better. Elevated Th17 levels following treatment are associated with recurrences of cervical and vulvar cancer. We are characterising the role of succinate in this process.

#CervicalCancer

Dr. Elisabeth Meedt

@Regensburg University Hospital

Antibiotics following stem cell transplantation – a curse or a blessing? We are investigating calprotectin as an indicator of bacterial translocation and changes in the microbiome – to provide a more rational basis for decision-making regarding the use of antibiotics.

#Haematology

Prof. Dr. Raphael Reuten 

@Albert Ludwig University of Freiburg

The mechanics of the basement membrane influence how lung adenocarcinomas develop and progress – an underestimated factor. We are investigating the biomechanical properties of the extracellular matrixas a new therapeutic target in lung
cancer.

#LungCancer

Prof. Dr. Volker Dötsch

@Johann Wolfgang Goethe University, Frankfurt am Main

p53 is mutated in one in every two tumours – and was long considered untreatable. We are developing tailored DARPin proteins, which correct structural hotspot mutations in the p53 DNA-binding domain and reactivate the tumour suppressor.

#MolecularBiology

Dr. Nadine Bayerl 

@Erlangen University Hospital

Predicting prostate cancer requires the integration of many data sources. We are developing an AI-powered chatbot that links imaging biomarkers, clinical parameters and body composition in a multimodal way – for personalised risk assessment.

#ProstateCancer

Dr. Isabel Poschke

@German Cancer Research Centre

Gliomas respond very little to immunotherapies – too few antigens, too severe immunosuppression. We are developing pan-HLA-reactive T-cell receptors for adoptive T-cell therapy, which can be used regardless of the patients’ HLA type.

#Neurooncology

Prof. Dr. Florian Heidel

@Hannover Medical School

CAT6A fusion oncogenes affect epigenetic regulators and drive rare, highly aggressive leukaemias. We are investigating, for the first time, the leukaemogenesis of these entities and examine whether targeted inhibition opens a clinically relevant therapeutic approach.

#Haematology

Dr. Marius Mader 

@Hamburg-Eppendorf University Hospital

Paediatric high-grade gliomas are virtually untreatable – the tumour microenvironment plays a crucial role. We are modelling in vivo how microglia cells are reprogrammed by tumour cells and end up supporting the tumour rather than the immune system.

#paediatriconcology

Prof. Dr. Thomas Rösch 

@University Medical Centre Hamburg-Eppendorf

The surgical removal of early-stage oesophageal cancer carries significant risks – organ-preserving endoscopy is an attractive alternative. We are conducting a wide analysis of risk factors for recurrence to refine the selection criteria for this treatment.

#gastroenterology

Dr. Fung-Yi Cheung

@Essen University Hospital

Ductal adenocarcinoma of the pancreas is almost impossible to control despite chemotherapy – desmoplastic stroma and progranulin promote resistance. We are investigating progranulin as a target to make the tumour microenvironment more
accessible to chemotherapy.

#PancreaticCancer

PD Dr. Hanna-Mari Baldauf 

@Ludwig Maximilian University of Munich

SAMHD1 protects AML cells from the chemotherapy drug Ara-C. We are using novel Vpx virus-like particles to specifically degrade SAMHD1 – and are testing this approach not only in leukaemias, but also in solid tumours.

#Haematology

Dr. Tamas Rasko 

@Würzburg University Hospital

CAR-T cell therapies work – but random genomic integration carries risks. We are developing a sequence-specific ‘Sleeping Beauty’ transposon system for the targeted, safe integration of CAR genes: genomically safe cell therapy of the next generation.

#CellTherapy

Prof. Dr. Ian Frew  

@Albert Ludwig University of Freiburg

Clear-cell renal cell carcinomas often remain incurable at the metastatic stage. We have identified that tumour cells exploit aberrant tubular repair mechanisms – and are investigating whether this vulnerability can be exploited for new therapeutic
approaches.
