Toward Diagnosis of Diabetes by NMR and Mulitvariate Analysis: Study of 1H NMR Spectra of Human Serum in an Integrated Working Environment

In order to improve the efficiency of NMR-based metabolomics studies, we have developed KnowItAll® Informatics System, Metabolomics Edition as a consistent and integrated software environment that covers the entire process from processing raw NMR data —to multivariate analysis—to biomarker identification. Using two datasets of 1H NMR spectra of mouse urine and human serum, we demonstrate the high efficiency of this integrated workflow for metabolomics data analysis.

Gene Experssion-based Prediction and Mechanistic Assessment of Non-Genotoxic Chemical-Induced Hepatocarcinogenicity

To facilitate both prediction and mechanism-based assessment of human cancer risk, a liver gene expression signature was derived from short term experiments in the rat to predict non-genotoxic hepatocarcinogenicity. The signature was shown to classify 47 independent chemicals with 85% accuracy, much greater than other putative early biomarkers.

Effective Fishing of Characteristic Proteome Fractions and Identification of Biomarkers Therein: Application of VisualCockpit to Multidimensional Chromatogram and MS Data

Characteristic 2D fractions are rapidly identified among thousands using interactive visualization, filtering and data mining with VisualCockpit. Biomarker candidates are found therein after identifying proteins from sequence tags. VisualCockpit correlates their concentrations, reflected by normalized MS peptide peak height sum, enzyme activity and immunoreactivity, to donor conditions.

Metabonomics for MolPAGE Discovering Diabetes Biomarkers

MolPAGE (Molecular Phenotyping to Accelerate Genomic Epidemiology) is an EU consortium with almost twenty collaborating universities and companies throughout Europe. One of the aims of MolPAGE is to find early onset biomarkersfor type 2 diabetes (T2DM) and cardio-vascular diseases(CVD).
