The Nobel Prize in Chemistry for 2002 was shared by John B. Fenn and Koichi Tanaka "for their development of soft desorption methods for mass spectrometric analyses of biological macromolecules". Indeed, electrospray ionization and soft laser desorption ionization have proved to be of great value in "omics", such as metabolomics, transcriptomics and proteomics in providing a systematic and quantitative approach to the study of biological systems and networks. Moreover, these techniques have made great contributions to metabolic studies that are used for development of new drugs, as well as to the diagnosis of diseases including cancer based on the specific and sensitive detection of molecular biomarkers. In this article, we describe our recent results on characterization of bile acid metabolism in hepatobiliary disease as well as measurement of conjugated urinary tetrahydrocorticosteroids for assessment of altered corticoid metabolism in endocrine disease and the metabolic syndrome.
