Amino acid analysis using chromatography-mass spectrometry: An inter platform comparison study.
J. Pharm. Biomed. Anal. 114 , 398-407, (2015) The analysis of amino acids has become a central task in many aspects. While amino acid analysis has traditionally mainly been carried out using either gas chromatography (GC) in combination with flame ionization detection or liquid chromatography (LC) with e... |

Inactivation of human salivary glutathione transferase P1-1 by hypothiocyanite: a post-translational control system in search of a role.
PLoS ONE 9(11) , e112797, (2014) Glutathione transferases (GSTs) are a superfamily of detoxifying enzymes over-expressed in tumor tissues and tentatively proposed as biomarkers for localizing and monitoring injury of specific tissues. Only scarce and contradictory reports exist about the pre... |

High-Throughput Assay Development for Cystine-Glutamate Antiporter (xc-) Highlights Faster Cystine Uptake than Glutamate Release in Glioma Cells.
PLoS ONE 10 , e0127785, (2015) The cystine-glutamate antiporter (system xc-) is a Na+-independent amino acid transporter that exchanges extracellular cystine for intracellular glutamate. It is thought to play a critical role in cellular redox processes through regulation of intracellular g... |

A quantitative metabolomics peek into planarian regeneration.
Analyst 140 , 3445-64, (2015) The fresh water planarian species Schmidtea mediterranea is an emerging stem cell model because of its capability to regenerate a whole animal from a small piece of tissue. It is one of the best model systems to address the basic mechanisms essential for rege... |

Image-based RNA interference screening reveals an individual dependence of acute lymphoblastic leukemia on stromal cysteine support.
Oncotarget 5(22) , 11501-12, (2014) Interactions with the bone marrow microenvironment are essential for leukemia survival and disease progression. We developed an imaging-based RNAi platform to identify protective cues from bone marrow derived mesenchymal stromal cells (MSC) that promote survi... |

Dietary methionine can sustain cytosolic redox homeostasis in the mouse liver.
Nat. Commun. 6 , 6479, (2015) Across phyla, reduced nicotinamide adenine dinucleotide phosphate (NADPH) transfers intracellular reducing power to thioredoxin reductase-1 (TrxR1) and glutathione reductase (GR), thereby supporting fundamental housekeeping and antioxidant pathways. Here we s... |

Physiological Roles and Adverse Effects of the Two Cystine Importers of Escherichia coli.
J. Bacteriol. 197 , 3629-44, (2015) When cystine is added to Escherichia coli, the bacterium becomes remarkably sensitive to hydrogen peroxide. This effect is due to enlarged intracellular pools of cysteine, which can drive Fenton chemistry. Genetic analysis linked the sensitivity to YdjN, a se... |
