The goal of the department is to use Systems Biology approaches to unravel the mechanisms underlying inborn and acquired metabolic diseases. We aim to understand how different proteins and metabolites in a complex metabolic network modulate disease outcome. This helps us to understand which people are at risk and develop personalized therapies. Our approach is based on interplay between experimental work and computational modeling.
Our department has established computational models on a range of pathways mostly related to central energy metabolism. Furthermore, we have an established workflow for quantitative, targeted proteomics applications. Assays including standards are available for pathways in energy metabolism (glycolysis, mitochondrial fatty-acid oxidation, TCA cycle and respiration). Within the various projects the models and targeted proteomics assays are being extended and these applications provide potential valuable tools for other research questions related to the same biological processes. Finally, we work on targeted metabolomics approaches, including workflows for analysis of stable isotopes.

Expertise and Track Record
Prof Dr. Bakker is coordinator of Marie Skłodowska Curie International Training Network ‘PoLiMeR’ (Polymers in the Liver: Metabolism and Regulation); www.polimer-itn.eu.
She applies the Systems Biology approaches for the computational modelling of metabolic networks based on ordinary differential equations and enzyme kinetics. The analytical platforms to support the modeling include targeted metabolomics and stable isotope fluxomics for specific metabolites.
Dr. Wolters has established the targeted proteomics workflow within the department for various applications. The method development of the mitochondrial targets has been published as methodology paper (Wolters, 2016) and the applications for the modeling are amongst others, published in relation to the MCAD deficiency mouse models (van Eunen, 2016) and a study dedicated to mouse aging mechanisms (Stolle, 2018). The developed methods have already been applied by external collaborators as well (Janssens 2017; van Erp, 2018).
Alternative applications for the targeted proteomics ranged from targeting proteins related to the bile acid metabolism (Hoogerland, 2019), quantification of patient specific (heterozygote) mutations in patients (Oldoni, 2018) to quantification of protein complexes in combination with silencing of specific components in these complexes (Fedeseioenko, 2018). Additionally, all assays are developed in such way that they are applicable both for human and mouse targets, making them widely applicable for animal models, cell lines and patient materials alike.
