Non-targeted metabolomics technologies have the potential for providing novel biomarkers of disease and drug efficacy, and are increasingly being incorporated into biomarker exploration studies. Contextualization of metabolomics results is enhanced by integration of study data from other platforms, such as transcriptomics, thus linking known metabolites and genes to relevant biochemical pathways. In the current study, urinary NMR-based metabolomic and liver, adipose, and muscle transcriptomic results from the db\/db diabetic mouse model are described. To assist with cross-platform integration, integrative pathway analysis was used. Sixty-six metabolites were identified in urine that discriminate between the diabetic db\/db and control db\/+ mice. The combined analysis of metabolite and gene expression changes revealed 24 distinct pathways that were altered in the diabetic model. Several of these pathways are related to expected diabetes-related changes including changes in lipid metabolism, gluconeogenesis, mitochondrial dysfunction and oxidative stress, as well as protein and amino acidmetabolism. Novel findings were also observed, particularly related to the metabolism of branched chain amino acids (BCAAs), nicotinamidemetabolites, and pantothenic acid. In particular, the observed decrease in urinary BCAA catabolites provides direct corroboration of previous reports that have inferred that elevated BCAAs in diabetic patients are caused, in part, by reduced catabolism. In summary, the integration of metabolomics and transcriptomics data via integrative pathway mapping has facilitated the identification and contextualization of biomarkers that, presuming further analytical and biological validation, may be useful in future T2D clinical studies by identifying patient populations that share common disease pathophysiology and therefore may identify those patients that may respond better to a particular class of anti-diabetic drugs.<\/jats:p>\n                  <jats:p\/>","DOI":"10.1039\/b914182k","type":"journal-article","created":{"date-parts":[[2010,3,23]],"date-time":"2010-03-23T08:00:14Z","timestamp":1269331214000},"page":"909-921","source":"Crossref","is-referenced-by-count":163,"title":["Integration of metabolomics and transcriptomics data to aid biomarker discovery in type 2 diabetes"],"prefix":"10.1093","volume":"6","author":[{"given":"Susan C","family":"Connor","sequence":"first","affiliation":[{"name":"Discovery Research a , GlaxoSmithKline, Ware UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael K","family":"Hansen","sequence":"additional","affiliation":[{"name":"Discovery Research b , GlaxoSmithKline 709 Swedeland Rd., King of Prussia, PA 19406, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam","family":"Corner","sequence":"additional","affiliation":[{"name":"Ingenuity Systems Inc. c , 1700 Seaport Blvd. Third Floor, Redwood City, CA 94063, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Randall F","family":"Smith","sequence":"additional","affiliation":[{"name":"Safety Assessment d , GlaxoSmithKline 709 Swedeland Rd., King of Prussia, PA 19406, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Terence E","family":"Ryan","sequence":"additional","affiliation":[{"name":"Discovery Research b , GlaxoSmithKline 709 Swedeland Rd., King of Prussia, PA 19406, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2010,3,23]]},"reference":[{"key":"2026012913192295600_cit1","author":"FDA, Challenge and opportunity on the critical path to new medical products, in: US FDA, 2004"},{"issue":"1","key":"2026012913192295600_cit2","doi-asserted-by":"crossref","first-page":"45","DOI":"10.1038\/83496","article-title":"A functional genomics strategy that uses metabolome data to reveal the phenotype of silent mutations","volume":"19","author":"Raamsdonk","year":"2001","journal-title":"Nat.
