Development of Isotope Labeling Liquid Chromatography Mass Spectrometry for Biofluid Metabolomics and Applications in Disease Studies
DownloadSpring 2014
Metabolomics is a research field focusing on global study of all the metabolites present in a biological system (i.e., the metabolome). Metabolome analysis involves identifying and quantifying as many small molecule metabolites as possible in a biological sample. Metabolomics has attracted much...

Development of isotope labeling liquid chromatography mass spectrometry for metabolome analysis
DownloadSpring 2011
As the endpoint of the “omics” cascade, metabolomics has attracted much attention in the discovery of diagnostic or prognostic disease biomarkers, and as a powerful tool to understand biological and biochemical processes and mechanisms. The objective of my research was to develop a highly...

Development of Isotope Labeling Methods and Data Processing Program for Liquid Chromatography Mass Spectrometry-Based Metabolome Analysis
DownloadSpring 2014
Metabolomics strives to gain a comprehensive picture of the metabolites in a biological system. This emerging research field gives us an insight into the discovery of disease-related biomarkers and an understanding of metabolic flux as well as mechanisms. Liquid chromatography mass spectrometry...

Development of Liquid Chromatography Mass Spectrometry Methods for the Identification and Quantification of Acylcarnitines in Biological Samples
DownloadFall 2012
The field of metabolomics follows the Greek premise where metabolic changes are believed to be indicative of disease. Acylcarnitines, for example, can be dysregulated in the presence of various diseases including genetic metabolic disorders and multiple sclerosis. Liquid chromatography mass...

Development of Mass Spectrometric Methods for Membrane Proteome Analysis and Protein Sequence Mapping
DownloadSpring 2014
This thesis work mainly focused on the development of mass spectrometric methods for membrane proteome analysis and protein sequence mapping. First, the comparison of the performance of RapiGest-, PPS- and SDS-based sample preparation methods for shotgun membrane proteome analysis was...

Differential 15N2-/14N2-isotope Dansylhydrazine Labeling and LC-MS for Quantification of the Human Carbonyl Metabolome
DownloadFall 2011
The objective of this work was the design and use of paired labeling reagents that are chemically identical but isotopically different to provide a simple and robust means of quantitative mass spectrometry (MS) based metabolome profiling. Herein is presented the differential 15N2-/14N2-isotope...

Functional and topological analysis of yeast acyl-CoA:diacylglycerol acyltransferase 2, an endoplasmic reticulum enzyme essential for triacylglycerol biosynthesis
Download2011
Siloto, Rodrigo M. P., Snyder, Crystal L., Liu, Qin, Weselake, Randall J.
Acyl-CoA:diacylglycerol acyltransferase (EC 2.3.1.20) is a membrane protein present mainly in the endoplasmic reticulum. It catalyzes the final and committed step in the biosynthesis of triacylglycerol, which is the principal repository of fatty acids for energy utilization and membrane...
