Temporal Dynamics of Pathogenesis Related Metabolites and their Metabolic Pathways Following Inoculation of Potato Leaves with Phytophthora infestans
Y. Abu-Nada, A. C. Kushalappa, W. D. Marshall, K. Al-Mughrabi, and A. Murphy

The resistance in potato cultivars against late blight caused by Phytophthora infestans is classified into vertical and horizontal. Several metabolites associated with resistance have been detected: phytoalexins such as rishitin, phytuberin, lubimin, solavetivone etc. Metabolite profiling is a novel technology for the discrimination of quantitative resistance in plants against pathogen stress.

Towards Understanding of Ryegrass-Endophyte Symbiosis through Data Integration of Transcriptome and Metabolome
Mingshu Cao, Linda Johnson, Albert Koulman, Geoff Lane and Susanne Rasmussen

Combined with extensive bioinformatics analyses, our joint analysis of transcriptomics and metabolomics data has generated interesting findings which led to further laboratory verification, such as potential genes associated with alkaloid production.

Ethnopharmacological Evaluation of Radal (leaves of Lomatia hirsuta) through Metabolite Profiling and Isolation of 2-Methoxyjuglone.
Henrik Toft Simonsena, Louise Berthelsenb, Anne Adsersenb, Søren Brøgger Christensenb, Alfonso Guzmánb and Per Mølgaardb

To evaluate the efficacy of the traditionally used herbal remedy Radal a metabolite profile of the original plant material was established. The EtOAc extract of the leaves and found to be active against the pathogenic fungus Candida albicans (MIC = 8 µg/ml). Cinnamic acid (2) and vanillic acid (5) were identified as the major constituents in the tea by GC-MS along with other phenolic derivatives.

The Comparison of Lipid Extraction Methods for the Lipidomic Analysis of Human Blood Plasma
Ali Awwad, Catharine Ortori, Dave A. Barrett and Clare A. Daykin

Although metabolomics is and should remain an integrated approach by itself, its complexity requires analogous approaches focused on its components, such as lipidomics. Lipid profiling by NMR without sample extraction, should be seen as only the first stage in lipidomic analysis. Subsequent analysis should involve extraction of the lipids from the biofluid or tissue prior to further profiling using a multi-technique metabolomic approach involving both NMR and MS.

Biomarker Identification Combining Multivariate Analysis of NMR Spectra with an Innovative Spectral Data Analysis Approach in an Integrated Working Environment
Regis Grenier, Yann Bidault, Chen Peng, Gregory M. Banik, Scott Ramos, Brian Rohrback, Tao Wang and Bin Xia,

A recently developed Metabolomics informatics solution from raw data processing to metabolite database searching, compatible with multiple instruments, has been successfully applied to the analysis of 1H NMR human serum spectra of diabetic and non-diabetic subjects. This study also highlights Overlap Density Heatmap, a novel technology that complements the use of chemometrics in biomarker identification.

Constructing Directed Metabolic Networks from Microarray Data
J. M. Easton, T. N. Arvanitis, A. Peet and M. Viant

Although it has been several years since metabolic networks became a commonly used analysis technique in bioinformatics, the question of how best to construct them from experimental data is still not satisfactorily resolved. Here we present a method for the construction of directed metabolic networks from microarray datasets using an enhanced version of the KEGG LIGAND database.

Application of 1H NMR Metabolomics to a Murine Model of Inflammatory Arthritis
Reza Dowlatabadi, B. Joan Miller, Frank R. Jirik, Hans J. Vogel and Aalim M. Weljie

The novel quantitative technique of "Targeted Profiling" of 1H 1D NMR data is applied to a unique model of rheumatoid arthritis. A number of candidate biomarkers not previously identified using NMR techniques are identified related to inflammation and immune response. The pharmaceutical relevance of several of these metabolites is discussed.

Herbal Metabolic Profiling of Raw and Steamed Panax notoginseng
Eric C.Y. Chan, Swee-Lee Yap, Aik-Jiang Lau, Pay-Chin Leow, Ding-Fung Toh, and Hwee-Ling Koh

At present, metabolite profiling is of growing importance in herbal medicine fields such as breeding, formulation, quality control and clinical trials. Herbal metabolic profiling allows direct detection of down-stream derivatives of metabolites, arising from herbal formulation process, using metabolite profiling ultra performance liquid chromatography time-of-flight mass spectrometry.
