  • Remond Fijneman (NKI): "Access, query and view your translational research study in cBioPortal: the MEDOCC use case"
    Translational research studies face significant challenges with respect to data management and data analysis. Longitudinal clinical, imaging, biobanking and molecular data need to be collected and integrated to access, query and view translational research data. cBioPortal is an open-access, open-source resource for interactive exploration of multidimensional (cancer) genomics data sets. The cBioPortal tool is adopted and supported by Health-RI to facilitate multicenter translational research studies that are initiated in the Netherlands. One of these studies is PLCRC-MEDOCC, referring to Molecular Early Detection Of Colorectal Cancer (MEDOCC) as a substudy of the national prospective colorectal cancer cohort study (PLCRC). The aim of the PLCRC-MEDOCC study is to investigate cell-free circulating tumor DNA (ctDNA) as a biomarker for minimal residual disease in stage II and stage III colon cancer. The MEDOCC use case will be presented as an example of an international multicenter translational research study for which longitudinal clinical, biobanking and molecular data are currently being collected and integrated.

Watch recorded workshop 3

  • Patrick Deelen (UMCU & UMCG): "Reconciling GWAS and Mendelian genetics through core-gene identification using Downstreamer"
    I will show how we use genetics and RNA-seq to prioritize the important genes of common diseases and traits, such as auto-immine disorders and height. We observed that these prioritized genes are enriched for genes that cause rare diseases when damaged. This shows the shared biology of common and rare diseases.
  • Reconciling GWAS and Mendelian genetics through core-gene identification using Downstreamer

  • Gennady Roshchupkin (Erasmus MC): "Artificial Intelligence and multi-omics data: Better, Faster, Stronger"
    In this talk we will discuss the latest development in AI technologies (machine learning and deep learning) in application to various omics data. How such algorithms can help to analyze data and make new discoveries. What are the obstacles we need to overcome first and what are the new opportunities AI can bring to omics field?
  • Artificial Intelligence and multi-omics data: Better, Faster, Stronger

  • Erik van den Akker (LUMC): "Metabolomics-based predictors as markers of health and disease"
    The blood metabolome incorporates cues from the environment and the host’s genetic background, potentially offering a holistic view of an individual’s health status. Using vast resources of proton nuclear magnetic resonance metabolomics and phenotypic data we constructed predictors for mortality, biological age, and a wide array of cardio-metabolic variables routinely assessed in large epidemiological studies. For the mortality and biological age predictors we show associations with various clinical end points, suggesting that they pick up on a broad range of health aspects. We illustrate the value of the predictors for cardio-metabolic variables by using them to impute missing phenotypic data that can be employed for downstream association analyses.

  • Jan Koster

    Workshop #2

    After having been educated as a molecular biologist (Utrecht University), and subsequently trained as a cell biologist at the Netherlands Cancer Institute (NKI) (supervised by Prof. A. Sonnenberg), Jan Koster switched career to the at that time developing field of bioinformatics in 2003. He joined the team of Prof. Versteeg, and in 2007 obtained a staff position within the department with his own team of bioinformaticians. His group currently consists of 6 bioinformaticians. The focus of Koster’s group is on applied bioinformatics, where they try to bridge the gap between the molecular biologists and the complex data that they are generating using high throughput technologies. Aside from helping the biologists with the processing, analysis and interpretation of HT data, they have heavily invested in an idea conceived in 2005. ‘Wouldn’t it be great if molecular biologists could analyze and explore their own data’. With this aim in mind and their biology background and mindset they have developed the web-based R2 genomic analysis and visualization platform ( R2 is composed of a dedicated database containing the HT data, coupled to a web-based suite of analysis and visualization tools that can be operated by users without bioinformatics training. R2 handles many types of genomics data from mRNA gene expression to whole genome sequencing data. The success of this concept can be illustrated by a user base of 140,000+ users (IP-addresses) from around the world, ~2,000,000 page views a year and over 1,500 citations in PubMed listed publications (Jan 2021). Driven by user feedback and technological advances they are constantly improving R2 and extending it with new options. Koster also conducts research in new ways of making complex data insightful. With their biology driven focus, they have been fortunate to be involved in many collaborations with research groups around the globe, which has already resulted in authorships on 30+ high impact publications.

He develops and applies methods for the integrative analysis of large-scale biological, epidemiological and clinical data. The group uses the latest approaches in genomics, medical imaging, computer science, statistics and machine learning to sort through increasingly rich and massive amount of data. The goals are to improve the understanding of how various omics affect the complex traits and to make use of such insights to improve the diagnosis, prevention and treatment of diseases whenever possible.

  • Erik van den Akker

    Workshop #3

    I have a keen interest in studying the ageing hematopoietic and immune system and its effects on health. I performed most of my (post)doctoral training within (inter)national collaborative projects NCHA, IDEAL and BBMRI that aimed to elucidate the determinants contributing to healthy ageing. During this period, I specialized in developing methods for the integrative analysis of omics datasets within cross-disciplinary research. I'm currently working as an assistant professor on various computational topics, including the development of broadly applicable omics predictors for clinical outcomes and risk factors. In parallel, I perform research on the ageing hematopoietic system and its age-related changes to pre-leukemia, i.e. ‘age-related clonal hematopoiesis’, as highlighted by papers in Blood (Van den Akker et al. 2016) and Leukemia (van den Akker et al. 2020). Interestingly, age-related clonal hematopoiesis not only predisposes to hematologic malignancies, yet is also associated with a higher incidence of various low-grade inflammatory diseases, i.e. cardiovascular disease, and outcomes, i.e. cardiovascular mortality. I was awarded a Veni personal grant of the Dutch Research Council in 2019 to study the heterogeneity in clonal-hematopoiesis related outcomes using omics platforms. I was invited to the management team of the newly established Leiden Center for Computational Oncology (LCCO) to develop omics predictors for diagnostic and prognostic applications in acute myeloid leukemia.
