Pedersen,Steven R. Smith,Fiona Bamforth,Russell Greiner,Bruce M. McManus,John W. Newman,Theodore L. Goodfriend,David S. Wishart,David S. Wishart +24 more
TL;DR: This work has combined targeted and non-targeted NMR, GC-MS and LC-MS methods with computer-aided literature mining to identify and quantify a comprehensive, if not absolutely complete, set of metabolites commonly detected and quantified (with today's technology) in the human serum metabolome.
Journal ArticleDOI
The Human Urine Metabolome
Souhaila Bouatra,Farid Aziat,Rupasri Mandal,An Chi Guo,Michael Wilson,Craig Knox,Trent C. Bjorndahl,Ramanarayan Krishnamurthy,Fozia Saleem,Philip B. Liu,Zerihun T. Dame,Jenna Poelzer,Jessica Huynh,Faizath S. Yallou,Nick Psychogios,Edison Dong,Ralf Bogumil,Cornelia Roehring,David S. Wishart,David S. Wishart +19 more
TL;DR: A comprehensive, quantitative, metabolome-wide characterization of human urine and the identification and annotation of several previously unknown urine metabolites and to substantially enhance the level of metabolome coverage are undertaken.
Journal ArticleDOI
Progeny of tobacco mosaic virus-infected Nicotiana tabacum plants exhibit trans-generational changes in metabolic profiles
Rupasri Mandal,Palak Kathiria,Nikolaos Psychogios,Souhaila Bouatra,Ramanarayan Krishnamurthy,David S. Wishart,Igor Kovalchuk +6 more
TL;DR: Viral infections can lead to trans-generational or heritable metabolic changes to plants, and infection of Nicotiana tabacum plants with tobacco mosaic virus results in transgenerational changes in plant phenotype.
Journal ArticleDOI
Differential metabolite profiles and salinity tolerance between two genetically related brown-seeded and yellow-seeded Brassica carinata lines.
Thomas Canam,Xiang Li,Xiang Li,Jennifer Holowachuk,Min Yu,Jianguo Xia,Rupasri Mandal,Ramanarayan Krishnamurthy,Souhaila Bouatra,Igor Sinelnikov,Bianyun Yu,Larry Grenkow,David S. Wishart,Harold Steppuhn,Kevin C. Falk,Tim J. Dumonceaux,Margaret Y. Gruber +16 more
TL;DR: The data indicate that the brown-seeded line has greater sodium tolerance than the yellow-seed line, provide clues to the biochemical underpinnings for the phenotypic variation, and highlight the utility of B. carinata as a biorefinery crop for saline land.
Journal ArticleDOI
Metabolomic Analysis of Cold Acclimation of Arctic Mesorhizobium sp. Strain N33
Abdollah Ghobakhlou,Serge Laberge,Hani Antoun,David S. Wishart,Jianguo Xia,Ramanarayan Krishnamurthy,Rupasri Mandal +6 more
TL;DR: Isobutyrate was highly upregulated (19.4-fold) during growth at 4°C, thus suggesting that this compound is a precursor for the cold-regulated fatty acids modification to low temperature adaptation.
