Topic: Towards personalized approaches for relapsed and refractory childhood leukemia

Jean-Pierre Bourquin is the elected chair of the largest division in pediatric Hematology/Oncology in Switzerland and directing a large translational research effort within the Comprehensive Cancer Center Zurich at the at the Children’s Research Centre at the University Children’s Hospital in Zurich. He is a physician scientist with an active clinical and translational research program. Since 2019, he chairs the resistant disease committee of the international BFM Study Group, which is the central organization in Europe that leads the development of new treatments for childhood leukemia and have initiated a Scientific Working Group for functional  precision hematology for  the European Society of Hematoloty in 2019.

His research focus is on transcriptional dependencies and mechanisms of drug  resistance in childhood acute lymphoblastic leukemia (ALL). Over the last decade the Bourquin group has built and characterized a large repository of patient-derived xenografts within the framework of our international clinical studies. This constitutes a comprehensive model and a renewable resource to address mechanistic research directly in the relevant cancer cells. Using this model they have developed a functional screening platform for precision medicine that will be implement in clinical trials within the international BFM study group (application of drug response profiling to individualize treatment components for relapsed and refractory ALL). Using this model, they are dissecting different aspects of the biology of resistant disease. We have a program to define the leukemia microenvironment, are dissecting the function of relevant fusion transcription factors such as TCF3-HLF, which defines a paradigm of resistant ALL and highjacks a stem cell program driven by the master regulator transcription factor HLF, and are exploring new phenotypes that emerge from our comprehensive modelling approach. Relevant for this application, we have identified a signature that is highly associated with de novo resistance to chemotherapy in ALL (persistence of minimal residual disease). A key feature is the aberrant expression of the cell surface protein gp180, also called Vanin-2 or VNN2. This gene is only expressed in the hematopoietic system and markes a very early fetal stem cell compartment that also expresses HLF. VNN2 is also expressed in subsets of cord blood and adult hematopoietic stem cells, and in a later wave in differentiated myelomonocytic cells and lymphoid cells. In a prospective study, we confirm association of VNN2 by flow cytometry with MRD persistence in different genetic subgroups at risk. Given the association of VNN2 with stemness and inflammation, we seek to identify the underlying program with the aim to identify common actionable principles in resistant disease.

Schwiete-Laboratory for Microbiota and Inflammation, Deutsches Rheuma-Forschungszentrum (DRFZ) Berlin, a Leibniz Institute, Berlin, Germany

Topic:
T cells, Microbiota, Chronic Inflammation

Hyun-Dong Chang studied biology at the Free University Berlin and at the University of California, San Diego (UCSD). During his PhD thesis at the German Rheumatism Research Center (DRFZ) Berlin, he studied the regulation of cytokine expression in T cells. His research focused on the establishment and maintenance of a functional memory in T cells, in particular the molecular basis and prerequisites of epigenetic and functional imprinting of T cells for cytokine expression and the molecular adaptations of T cells to chronic inflammation allowing them to function and persist in inflamed tissue. He is the scientific leader of the flow cytometry core facility of the DRFZ and past president of the German Society for Cytometry (DGfZ). As the group leader of the Schwiete-Laboratory for Microbiota and Inflammation at the DRFZ, his current research activities focus on understanding the role of the intestinal microbiota in the prevention, triggering and maintenance of chronic inflammation.

Dr. Shyamala Maheswaran

Massachusetts General Hospital, Boston, USA

Topic: Epithelial to Mesenchymal Transition: A dynamic Process Contributing to Genomic Diversity​


Dr. Shyamala Maheswaran’s research  is focused on defining the molecular mechanisms that drive breast cancer progression and metastasis. Breast cancer, initially confined to the primary site, eventually spreads to distal sites, including lung, liver, bone and brain, by invading into the bloodstream. Upon reaching these distal sites, the tumor cells continue to grow and evolve well after removal of the primary tumor resulting in overt metastasis and disease recurrence, the leading causes of cancer-related deaths. Using cell culture and mouse models and patient derived tissues and circulating tumor cells (CTCs) enriched from breast cancer patients’ blood, Dr. Maheswaran's laboratory characterizes the contribution of oncogenic cues, tumor microenvironment-derived signals, epithelial to mesenchymal transition and tumor heterogeneity to breast cancer progression and therapeutic responses. She collaborates closely across several disciplines including Clinicians and Engineers at MGH and is currently the Scientific Director of the Center for Cancer Risk Assessment at the Massachusetts General Hospital (MGH).
