Journal ArticleDOI
Extraction and GC/MS Analysis of the Human Blood Plasma Metabolome
A Jiye,Johan Trygg,Jonas Gullberg,Annika I. Johansson,Pär Jonsson,Henrik Antti,Stefan L. Marklund,Thomas Moritz +7 more
TL;DR: An extraction and derivatization protocol, developed using experimental design theory, for analyzing the human blood plasma metabolome by GC/MS, suggests that the method could be usefully integrated into metabolomic studies for various purposes, e.g., for identifying biological markers related to diseases.
Journal ArticleDOI
An Auxin Gradient and Maximum in the Arabidopsis Root Apex Shown by High-Resolution Cell-Specific Analysis of IAA Distribution and Synthesis
Sara V. Petersson,Annika I. Johansson,Mariusz Kowalczyk,Alexander Makoveychuk,Jean Y. J. Wang,Thomas Moritz,Markus Grebe,Philip N. Benfey,Göran Sandberg,Karin Ljung +9 more
TL;DR: Fluorescence-activated cell sorting of green fluorescent protein–marked cell types combined with highly sensitive mass spectrometry methods are introduced as a novel means for analyses of IAA distribution and metabolism at cellular resolution to indicate that local biosynthesis and polar transport combine to produce auxin gradients and maxima in the root tip.
Journal ArticleDOI
High-throughput data analysis for detecting and identifying differences between samples in GC/MS-based metabolomic analyses.
Pär Jonsson,Annika I. Johansson,Jonas Gullberg,Johan Trygg,Jiye A,Bjørn Grung,Stefan L. Marklund,Michael Sjöström,and Henrik Antti,Thomas Moritz +9 more
TL;DR: A new semiautomated strategy using a hierarchical multivariate curve resolution approach that processes all samples simultaneously is described that generates tables of all the detected metabolites that differ in relative concentrations between samples.
Journal ArticleDOI
Environmental and hormonal regulation of the activity-dormancy cycle in the cambial meristem involves stage-specific modulation of transcriptional and metabolic networks.
Nathalie Druart,Annika I. Johansson,Kyoko Baba,Jarmo Schrader,Andreas Sjödin,Rupali Bhalerao,Lars Resman,Johan Trygg,Thomas Moritz,Rishikesh P. Bhalerao +9 more
TL;DR: The data reveal the dynamics of transcriptional and metabolic networks and identify potential targets of environmental and hormonal signals in the regulation of the activity-dormancy cycle in cambial meristem.
Journal ArticleDOI
Metabolomic Characterization of Human Prostate Cancer Bone Metastases Reveals Increased Levels of Cholesterol
Elin Thysell,Izabella Surowiec,Emma Hörnberg,Sead Crnalic,Anders Widmark,Annika I. Johansson,Pär Stattin,Anders Bergh,Thomas Moritz,Henrik Antti,Pernilla Wikström +10 more
TL;DR: Cholesterol is identified as a possible therapeutic target for advanced PCa after being identified in primary tumor tissue and in plasma which were significantly associated with metastatic disease.
