Computational Techniques and Systems For Metabolomics Analysis

Abstract

Metabolomics is a relatively new “omics” platform, which measures and analyzes a discreet set of small molecules (metabolites) detected in bio-fluids or tissue samples of organisms. Life scientists hypothesize about under-the-hood mechanisms of drug or disease related changes using metabolite measurements over the associated metabolic network of the organism. Given the high number of observations and complex relationships among metabolites, metabolomics analysis is a challenging task with a large search space. Therefore, efficient algorithms and user-friendly computer systems that embrace biochemical principles and guide life scientists through the hypothesis generation stage are needed. In this talk, I will describe two algorithms that serve this purpose. (1) Steady-State Metabolic Network Dynamics Analysis (SMDA) Algorithm that generates possible activation scenarios of the metabolic network, and (2) Algorithm to DEtermine Metabolic Alterations (ADEMA) that computes disease specific metabolic signatures given the metabolite measurements of the control and the variable groups. I will also make a demo on our metabolomics analysis systems: PathCaseMAW and PathCaseRECON, which are available online at nashua.case.edu.
