The mission of the core Lab is to provide the research platform, key technology, and standard operating protocols for metabolomics studies.
Metabolomics is a newly emerging field concerned with the comprehensive characterization of low-molecular-weight (LMW) metabolites in biological systems. Information obtained from metabolomics approach may provide a global view of the metabolic pathways, network, and their interactions in normal and pathophysiological states.
Accordingly, metabolomics-based information may help to detect disease progression, monitor response to treatment, and identify new targets for drug design. Since a global, unbiased approach is undertaken, metabolomics is most applicable to human degenerative diseases including diabetes, cardiovascular disease, and neurodegenerative diseases, which involve the interactions of multiple risk factors in disease pathogenesis and progression.
Metabolomics approach relies on nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS) as the key tools for untargeted metabolite profiling and target metabolite identification. Plasma, urine, CSF, cells and biospecimens are samples for analysis. Precise determination of metabolite concentration is not always necessary in an early stage. If specific metabolites (target metabolites) turn out to be important, the information of their concentrations becomes instructive.
