    Quantification of 2-Hydroxyglutarate Enantiomers by Liquid Chromatography-mass Spectrometry
    Authors:  William M. Oldham and Joseph Loscalzo, date: 08/20/2016, view: 9017, Q&A: 0
    [Abstract] Two enantiomers of 2-hydroxyglutarate (2HG), L (L2HG) and D (D2HG), are metabolites of unknown function in mammalian cells that were initially associated with separate and rare inborn errors of metabolism resulting in increased urinary excretion of 2HG linked to neurological deficits in children (Chalmers et al., 1980; Duran et al ...
    Extraction and Quantification of Tryptophan and Kynurenine from Cultured Cells and Media Using a High Performance Liquid Chromatography (HPLC) System Equipped with an Ultra-sensitive Diode Array Detector
    Authors:  Jeffrey Kim, Benjamin Stewart and Robert H Weiss, date: 04/05/2016, view: 7094, Q&A: 0
    [Abstract] Evidence of the involvement of tryptophan and its metabolite, kynurenine, in various biological processes including cancer is constantly expanding. Analysis of cell extracts and culture media can allow for quick snapshots of the metabolic fluctuations occurring in vitro. Here, we describe a method for metabolite extraction from mammalian ...
    [14C]-Tryptophan Metabolic Tracing in Liver Cancer Cells
    Authors:  Krishna S. Tummala and Nabil Djouder, date: 09/05/2015, view: 7530, Q&A: 1
    [Abstract] Nicotinamide adenine dinucleotide (NAD+) is a coenzyme for many NAD+-consuming proteins with diverse biological functions. Oscillations in NAD+ levels may influence several cellular signaling pathways. NAD+ synthesis via Preiss-Handler route (salvage reactions) has been extensively reported. However, the ...
