The proposed project will develop non-invasive assays based on magnetic resonance (MR) to study glucose metabolism and further the understanding of metabolic diseases such as cancer, non-alcoholic fatty liver disease and muscle dystrophy, aiming to provide a platform for personalized drug testing on organ-on-a-chip systems.
We use hyperpolarized 13C magnetic resonance imaging (MRI) and spectroscopy (MRS), where signals from endogenous molecules are detected with chemical specificity. This technique allows us to detect the chemical reaction kinetics of an individual metabolic pathway in real-time, in vivo and in a non-invasive manner. Hyperpolarized 13C MRI/MRS has been used to study metabolism in cells, in vivo in animals and it is already transitioning into phase I clinical trials (both in the USA and Europe). In our group, we aim to bring this technique to detect real-time metabolism in organ-in-chips, working on methodology for hyperpolarized 13C MR and organ-in-chip devices as well as identifying new biomarkers and potential MR probes of abnormal cell metabolism and biochemical pathways.
