Quantitative Imaging of D-2-Hydroxyglutarate in Selected Histological Tissue Areas by a Novel Bioluminescence Technique
Patients with malignant gliomas have a poor prognosis with average survival of less than 1 year. Whereas in other tumor entities the characteristics of tumor metabolism are successfully used for therapeutic approaches, such developments are very rare in brain tumors, notably in gliomas. One metabolic feature characteristic of gliomas, in particular diffuse astrocytomas and oligodendroglial tumo...
متن کامل2-Hydroxyglutarate is not a metabolite; D-2-hydroxyglutarate and L-2-hydroxyglutarate are!
In the recent study by Wang et al. (1), the prognostic significance of the assessment of serum 2-hydroxyglutarate (2-HG) concentrations in acute myeloid leukemia was investigated. The authors report that in 87% of the patients with high serum concentrations of 2-HG, mutations in isocitrate dehydrogenase (IDH)1/IDH2 occurred, versus 29% in the group with moderately high 2-HG concentrations. This...
متن کاملNuclear microscopy: a novel technique for quantitative imaging of gadolinium distribution within tissue sections.
All clinically-approved and many novel gadolinium (Gd)-based contrast agents used to enhance signal intensity in magnetic resonance imaging (MRI) are optically silent. To verify MRI results, a "gold standard" that can map and quantify Gd down to the parts per million (ppm) levels is required. Nuclear microscopy is a relatively new technique that has this capability and is composed of a combinat...
متن کاملIdentification of a dehydrogenase acting on D-2-hydroxyglutarate.
Extracts of frozen rat liver were found to catalyse the formation of 3H2O from DL-2-hydroxy[2-3H]glutarate. Three peaks of enzyme activities were observed on separation by chromatography on DEAE-Sepharose. The first and second peaks corresponded to an enzyme acting on L-2-hydroxyglutarate and the third peak corresponded to an enzyme acting on D-2-hydroxyglutarate, as indicated by competitive in...
متن کاملVisualization of Leishmania tropica Infection in BALB/c Mice by Bioluminescence Imaging
Background: Leishmania tropica is the cause of more than one form of leishmaniasis and lacks a known reservoir animal. This study compares the potential infectivity of recombinant and wild-type L. tropica in BALB/c mice. Methods: The potential infectivity of recombinant L. tropicaEGFP or L. tropicaEGFP-LUC by two different, the subcutaneous and intradermal, routes was compared using a range of ...
