Dieter Saur - Translational Cancer Research and Experimental Cancer Therapy
We are studying fundamental biologically and clinically relevant aspects of cancer: how it develops, progresses, spreads to distant sites, and why it becomes resistant to anti-cancer therapies.
Cancer arises from a complex and heterogeneous interaction of driver mutations that can affect hundreds of genes. The function of most of these genes, their interplay and how we can exploit cancer specific dependencies for therapy is largely unknown.
To understand the complexity of this disease, we are analyzing patient samples, model cancer subtypes in vitro and at the organismal level by genetic engineering. Our lab is developing and deploying innovative genetic tools, such as dual and triple recombinase systems, organoids as well as microscopy to understand the cross-talk of cells in tumors with different genetic makeups.
We perform in vitro studies, such as large-scale drug and genetic screens, and follow in vivo approaches to uncover the interaction of tumor cells with their environment. For example, we are exploring the complex communication between cancer cells and their neighbors to dissect how they escape immune attack and suppress the immune system or prevent chemotherapy from working. This allows us to identify novel vulnerabilities for cancer therapy and investigate the mechanisms that make cancer resistant to therapy.
Identifying therapeutic vulnerabilities, understanding metastasis and tackling primary treatment failure are among the most challenging problems in oncology. Our work explores new ways to target solid tumors more efficiently and translate these finding to clinical trials to improve the prognosis of cancer patients.
Our Mission: Understanding the biology of cancer to uncover therapeutic vulnerabilities.
Dieter Saur studied medicine in Munich and obtained his doctorate in gastroenterology at TUM’s university hospital, graduating summa cum laude and winning TUM’s doctoral award. His doctoral thesis and postdoctoral qualification (2006) investigated neuronal control of the intestine, i.e. “brain-gut” function. A clinician and a researcher in one person, Saur established a new focus on tumor diseases of the gastrointestinal tract in 2002. The use of new imaging procedures for early detection of gastrointestinal tumors and the development of novel therapeutic strategies for tumor subtypes are key topics of his research. A consultant of internal medicine specializing in gastroenterology since 2007, Chair of Translational Cancer Research since 2017 and Director of the Institute of Experimental Cancer Therapy since 2018, Saur has accumulated a range of awards and grants along the way – most recently the prestigious Consolidator Grant from the European Research Council (ERC) and the German Cancer Award for his work in pancreatic cancer.
