High-throughput metabolomics is a dynamically developing technology that enables the mass separation of complex mixtures at very high resolu-tion. Metabolic profiling has begun to be widely used in clinical research to study the molecular mechanisms of complex cell disorders. | ễFEBS Journal TICL - a web tool for network-based interpretation of compound lists inferred by high-throughput metabolomics Alexey V.

Metabolic profiling has begun to be widely used in clinical research to study the molecular mechanisms of complex cell disorders. Similar to trans-criptomics which is capable of detecting genes at differential states meta-bolomics is able to deliver a list of compounds differentially present between explored cell physiological conditions. The bioinformatics challenge lies in a statistically valid interpretation of the functional context for identified sets of metabolites. Here we present TICL a web tool for the automatic interpretation of lists of compounds. The major advance of TICL is that it not only provides a model of possible compound transformations related to the input list but also implements a robust statistical framework to estimate the significance of the inferred model. The TICL web tool is freely cmp. accessible at http proj Received 12 November 2008 revised 28 January 2009 accepted 2 February 2009 doi Knowledge of
