    Research profile

    Glycans are key players in many cellular processes. As abundant components on the cell surface, glycans are exposed to the environment, act as mediators of intercellular interactions and participate in the pathogen recognition by components of the immune system. Due to their crucial role in many important processes, abnormal glycosylation has been linked to the pathology of many diseases, such as the malignant transformation of cancer cells, certain neurodegenerative diseases and inflammation. As a non-templated, posttranslational modification, glycans are not amenable to investigations by traditional genetic techniques. Given their heterogenic nature, glycoprotein analysis faces technical challenges that require the development of new tools and strategies for a better investigation of these molecules. As a chemical biologist, I use chemical tools to address complex biological questions. I am particularly interested in elucidating the role of glycans in the pathology of diseases, such as cancer or certain genetic disorders of glycosylation that have been associated with abnormal glycosylation pattern.

     

    Glycosylation in Cancer

    Altered protein glycosylation has long been identified as a hallmark of cancer. Tumor immune evasion, tumor progression, metastatic spread and poor clinical prognosis have been linked to abnormal glycosylation pattern. However, the functional significance with respect to tumor progression and immune cell modulation are not well understood.

    The new established Cancer Therapy Research Center, integrated in the department of Biochemistry, is focusing on projects in molecular oncology with the goal of developing new technologies for cancer therapy. One concept is the use of tumor killing oncolytic viruses, which is based on tumor lysis by the virus followed by activation of the body’s own immune system to attack the tumor cells. Recent studies revealed that hiding the virus from the immune system by using certain cell carriers, significantly prolonged the life time of the virus and resulted in increased oncolysis and immune stimulation.

    Our goal is to understand the role of glycosylation in this process. In this context, we aim to elucidate glycosylation profiles in different stem, cancer and immune cells. Identifying the key players that support successful virus replication in cells and better understanding how altered surface glycosylation modulates the interaction with immune cells, will be the basis to improve the efficacy of stem cell-mediated delivery of oncolytic viruses and the successful development of cancer specific vaccines.

     

    Congenital Disorders of Glycosylation (CDGs)

    Congenital disorders of glycosylation (CDGs), are rare genetic diseases affecting enzymes involved in the assembly and processing of glycans. The clinical spectrum is broad, ranging from severe multisystemic phenotypes to symptoms restricted to specific organs. Today more than 100 district CDGs have been identified in humans, most of which affect the N-glycan biosynthesis, an essential process for the survival of all eukaryotes. However, little is known about the glycobiology underlying the pathology of CDGs, such as proteins and pathways that are impaired due to altered or truncated glycosylation.

    We aim to understand cause and consequences of altered protein glycosylation on a molecular level. Our goal is to explain the diverse clinical phenotypes in CDGs by linking aberrantly glycosylated proteins to impaired biological functions and pathways. We are investigating patient cells and generated knock out cell lines with a combination of multi-omics approaches and biochemical methods to identify proteins with impaired functions due to altered glycan structures. Thereby, we are elucidating new crucial functions of glycoproteins and unravel their role in essential biological pathways. The gain in this fundamental knowledge will contribute to better understand altered glycosylation pattern in other, more common diseases, such as cancer, neurodegenerative diseases and inflammation.

     

    Bioothogonal tool development for glycan analysis

    The analysis of glycans and glycoproteins is still very challenging. Bioorthogonal chemistry alleviates some of these problems by incorporating chemical handles into biomolecules and utilizing them to attach probes in a way that does not exhibit cross reactivity with the natural environment. To better analyze glycans and glycoproteins in our research, we constantly develop new bioorthogonal probes with a broad application spectrum. Our probes can be used for qualitative and quantitative analysis of glycoproteins and other biomolecules in multiple applications such as imaging, mass spectrometry, isolation and purification.
