INTRODUCTION Previous magnetic resonance spectroscopy (MRS) and mass spectroscopy studies have shown accumulation of 2-hydroxyglutarate (2HG) in mutant isocitrate dehydrogenase (IDH) gliomas. IDH mutation is known to be a powerful positive prognostic marker in malignant gliomas. Hence, 2HG accumulation in gliomas was assumed to be a positive prognostic factor in gliomas, but this has not yet be...
Although many complex diseases including cancer manifest aberrant cellular metabolism and chromatin structure, the molecular connection between two processes remains poorly understood. The metabolite, αketoglurate (αKG), is a critical co-factor for a number of chromatin modifying enzymes. Its structural analogue, 2-hydroxyglutarate (2HG), was recently identified as the product of cancer-associa...
Intradialytic hypotension (IDH) has plagued hemodialysis (HD) patients and their caregivers since the early days of renal replacement therapy. Its persistence in the current era is evident from the results of the 1426-patient Hemodialysis (HEMO) study in this issue of JASN in which a median of 12.5% of dialysis sessions were complicated by IDH requiring saline infusion, lowering the ultrafiltra...
An important goal of systems biology is to develop quantitative models that explain how specific molecular features give rise to systems-level properties. Metabolic and regulatory pathways that contain multifunctional proteins are especially interesting to study from this perspective because they have frequently been observed to exhibit robustness: the ability for a system to perform its proper...
The new 2016 WHO brain tumor classification defines different diffuse gliomas primarily according to the presence or absence of IDH mutations ( IDH-mt) and combined 1p/19q loss. Today, the diagnosis of anaplastic oligodendroglioma requires the presence of both IDH-mt and 1p/19q co-deletion, whereas anaplastic astrocytoma is divided into IDH wild-type ( IDH-wt) and IDH-mt tumors. IDH-mt tumors h...
BALB/c.DBA/2 Idh-1b-Ityr-Pep-3b congenic mice were developed by introgressively backcrossing the Idh-1b and Pep-3b markers of DBA/2 mice onto the BALB/c pi mice. This introduced a 30-centimorgan chromosome 1 segment of DBA/2 chromatin that contained the Ityr gene. BALB/c.DBA/2 Idh-1b-Ityr-Pep-3b mice were resistant to in vivo infections by Salmonella typhimurium, Mycobacterium bovis, and Leishm...
The three isozymes of isocitrate dehydrogenase in Saccharomyces cerevisiae differ in subunit structure, subcellular location, and cofactor specificity. The two mitochondrial isozymes, IDH and IDP1, are NAD- and NADP-specific, respectively. Several lines of evidence presented here confirm the importance of IDH to respiratory processes. Expression of IDH RNA and protein is low with growth on gluc...
AIM To determine the incidence of intradialytic hypertension (IDH) during hemodialysis (HD) in end-stage renal disease (ESRD) patients using acetate dialysate compared to those using bicarbonate dialysate. METHODS This study was a double-blind cross-over randomized clinical trial. The effect of acetate and bicarbonate dialysate on blood pressure was analyzed in two consecutive HD sessions. Th...
Introduction. Intradialytic hypotension (IDH) is a common complication during hemodialysis which may increase mortality risks. Low dose of Korean red ginseng (KRG) has been reported to increase blood pressure. Whether KRG can improve hemodynamic stability during hemodialysis has not been examined. Methods. The 8-week study consisted of two phases: observation phase and active treatment phase. A...
The recent identification of IDH mutations in gliomas and several other cancers suggests that this pathway is involved in oncogenesis; however effector functions are complex and yet incompletely understood. To study the regulatory effects of IDH on hypoxia-inducible-factor 1-alpha (HIF1A), a driving force in hypoxia-initiated angiogenesis, we analyzed mRNA expression profiles of 288 glioma pati...
