AU - McDonald, R. B.. PY - 1993. Y1 - 1993. N2 - The purpose of this investigation was to evaluate insulin-stimulated skeletal muscle glucose uptake in male Fischer 344 rats, age 6, 12, and 27 mo, fed either a sucrose (S: 66.6% sucrose, 17.6% protein, 6.4% fat) or sucrose-free (SF: 66.6% starch, 17.6% protein, 6.4% fat) diet for 3 mo. Skeletal muscle glucose uptake (R(g)) in perfused hindlimbs was estimated from the uptake and subsequent phosphorylation of radiolabeled 2-deoxyglucose (2DG) in the gastrocnemius (GN), extensor digitorum longus (EDL), and soleus (SOL) muscles. Rat hindlimbs were perfused at a rate of 10 ml · min-1 with a modified Krebs Henseleit buffer containing bovine red blood cells (hematocrit: 40%) and 5.85 mmole · L-1 glucose along with 358 pmoles · L-1 followed by 3580 pmoles · L-1 insulin. ...

2-Deoxyglucose autoradiography and histological procedures.Four to 5 d after the tracer injections, domains sharing the ocular dominance and orientation specificity of the injection sites were additionally labeled by 2-[14C]deoxyglucose autoradiography. Anesthesia was induced and maintained as described above and supplemented by a muscle relaxant (Flaxedil, gallamine triethiodide, 160 mg in 50 ml of saline, 3 ml · kg−1 · hr−1; Specia) to prevent eye movements. All strabismic animals (cats C1-C6) were stimulated monocularly through the eye that dominated the neurons at the injection site. The respective nonstimulated eye (left eye in cats C1, C2, C3, and C5; right eye in cats C4 and C6) was covered with a black contact lens and an additional black patch. Simultaneously with the onset of the visual stimulation, the cats received an intravenous injection of 2-deoxy-d-[U-14C]glucose (dose, 100 μCi/kg; specific activity, 295 μCi/mmol; Amersham). Visual stimuli were the same as those used for ...

Insulin binding and 2-deoxy-d-glucose uptake were compared in the soleus, plantaris, and extensor digitorum longus (EDL) muscles, in vitro, since the known biochemical profile of the soleus differs markedly from the other two. The present study showed that insulin binding increased in all three muscles with increasing concentrations of insulin in the range of 0.2- 30 nM. However, the increase in binding of insulin to soleus at each insulin concentration exceeded that observed in the other two muscles (P , 0.05). Differences between the plantaris and EDL were not significant. The quantity of insulin bound at each concentration also increased more rapidly in the soleus than in either the plantaris (P , 0.05) or EDL (P , 0.05). Basal and insulin-stimulated uptake of 2-deoxy-d-glucose was also greater in the soleus than in the other muscles (P , 0.05). Maximal 2-deoxy-d-glucose uptake occurred at 1 nM insulin in each of the three muscles. These results indicate that in metabolically distinct types ...

The apparent enhancement of 2-deoxy-D-glucose uptake by mouse 3T3 cells accompanying transformation by SV40 virus is not due primarily to an effect on the transport process but to enhanced phosphorylation of the sugar by intracellular kinases. Moreover, the effect is not specifically a function of the presence of the viral genome, but is a reflection of the overall growth rate and physiological state of the cell. ...

We assessed the effect of the vasodilating calcium channel blocker nitrendipine on glucose tolerance in young spontaneously hypertensive rats (SHR) (n = 15). The nitrendipine group received 1 g/kg chow for 3 weeks. Untreated SHR (n = 14) served as controls. At 3 weeks body weight was comparable, whereas systolic blood pressure was 157 +/- 9 mm Hg in nitrendipine-treated rats versus 191 +/- 10 mm Hg in controls (mean +/- SD, P , .00001). Fasting glucose was 6.8 +/- 2.7 mmol/L in nitrendipine-treated versus 8.9 +/- 1.5 mmol/L in control rats (P , .03). An intravenous glucose tolerance test (300 mg/kg) showed plasma glucose levels at 2, 5, 15, and 30 minutes to be significantly lower in the nitrendipine-treated group versus controls (two-way ANOVA, P , .03). Glucose utilization was estimated by the uptake of [3H]deoxyglucose after its intravenous administration (2 microCi/100 g body wt) to instrumented awake animals. Heart and striated muscle uptake was, respectively, 7983 +/- 5812 and 951 +/- 731 ...

Numerous laboratories have shown that hyperglycemia increases cerebral ischemic damage. This presumably results from increased lactate production and accumulation during ischemia. Although increased tissue lactic acidosis is associated with increased ischemic brain damage, this damage has not been directly linked to glycolytic flux. Because 2-deoxyglucose (2-DG) is a competitive inhibitor of glycolysis we tested its ability to reduce hyperglycemia-exacerbated ischemic brain damage. Severe forebrain ischemia was produced by the four-vessel occlusion model in rats. Four rats received 3 g/kg glucose and saline while a second group (n = 5) was injected with 3 g/kg glucose plus 1.6 g/kg 2-DG. A third group (n = 5) was treated with 1 g/kg glucose plus saline and a fourth group (n = 5) received 1 g/kg glucose and 1.6 g/kg 2-DG. All rats were injected i.p. 10 minutes prior to the ischemic insult with the same volume/kg body weight. All rats receiving the high dose of glucose alone (3 g/kg) were dead ...

We studied the uptake of 2-deoxy-D-glucose (2DG) and the synthesis of its phosphorylated product 2DG-6-phosphate (2DG-6P) by the retinas of the clawed frog (Xenopus laevis) and the bullfrog (Rana catesbeiana). Autoradiographs showed that most of the retinal 2DG uptake is by the photoreceptor layer. The 2DG accumulation by isolated Xenopus retinas was time and concentration dependent. The Kt for transport was 5.05 mM; Vmax was 6.99 X 10(-10) mol . mg-1 tissue wet weight min-1. The Km for 2DG-6P formation was estimated to be 2-3 mM and Vmax to be approximately 4 x 10(-9) mol . mg-1 min-1. 2DG uptake was inhibited competitively by glucose with a Ki of 2.29 mM. Exposure to light reduced 2DG uptake by no more than 10% as compared with dark uptake. Low sodium or ouabain (10(-4)-10(-7) M) treatment did not significantly alter 2DG uptake as compared with control retinas. In experiments upon intact, anesthetized bullfrogs, light reduced both the total amount of radioactivity acquired by the retina and ...

Purpose: To evaluate 2-deoxy-2-[18F]fluoro-d-glucose positron emission tomography imaging (18FDG-PET) as a predictive, noninvasive, pharmacodynamic (PD) biomarker of response following administration of a small-molecule insulin-like growth factor-1 receptor and insulin receptor (IGF-1R/IR) inhibitor, OSI-906.. Experimental Design: In vitro uptake studies of 3H-2-deoxy glucose following OSI-906 exposure were conducted evaluating correlation of dose with inhibition of IGF-1R/IR as well as markers of downstream pathways and glucose metabolism. Similarly, in vivo PD effects were evaluated in human tumor cell line xenografts propagated in athymic nude mice by 18FDG-PET at 2, 4, and 24 hours following a single treatment of OSI-906 for the correlation of inhibition of receptor targets and downstream markers.. Results: Uptake of 3H-2-deoxy glucose and 18FDG was significantly diminished following OSI-906 exposure in sensitive tumor cells and subcutaneous xenografts (NCI-H292) but not in an insensitive ...

TY - JOUR. T1 - Serum glucose. T2 - Effects on tumor and normal tissue accumulation of 2-[F-18]-fluoro-2-deoxy-D-glucose in rodents with mammary carcinoma. AU - Wahl, Richard L.. AU - Henry, Christine A.. AU - Ethier, Stephen P.. PY - 1992/6. Y1 - 1992/6. N2 - The positron-emitter-labeled glucose analogue 2-[fluorine-18]-fluoro-2-deoxy-D-glucose (FDG) accumulates into many cancers after intravenous injection, but the effect of serum glucose levels on FDG uptake in the tumor has not been extensively studied. In vitro, elevated media glucose levels markedly diminished FDG and FDG 6-phosphate uptake and retention in human adenocarcinoma cells, while insulin had no effect. Mammary cancers were established subcutaneously in 12 rats. Six control rats with mammary tumors were fasted overnight. Hyperglycemia was established in six rats by means of continuous glucose infusion (glucose clamp). All animals were then intravenously administered 50 μCi of FDG. Serum glucose levels were 87 mg/dL (4.83 mmol/L) ...

Our previous study demonstrated that microinjection of leptin into the ventromedial hypothalamus (VMH) dramatically increased glucose uptake in the heart, brown adipose tissue (BAT), and skeletal muscles, but not in white adipose tissue (WAT) in conscious unrestrained rats, as assessed in vivo by the 2-[3H]deoxyglucose method. Here we examined the role of the sympathetic nervous system and insulin in enhanced glucose uptake by tissues after hypothalamic leptin injection. Pretreatment with guanethidine significantly suppressed the increased glucose uptake by the tissues in response to leptin injected into the VMH, whereas bilateral adrenal demedullation had no significant effect. Treatment with propranolol but not phenoxybenzamine also decreased significantly enhanced glucose uptake by the tissues. We further examined the interaction of the effects of hypothalamic leptin and insulin administered peripherally by clamping the glucose concentrations at a constant level. When leptin was injected into ...

Recent reports using metabolism regulating drugs showed that nutrient deprivation was an efficient tool to suppress cancer progression. In addition, autophagy control is emerging to prevent cancer cell survival. Autophagy breaks down the unnecessary cytoplasmic components into anabolic units and energy sources, which are the most important sources for making the ATP that maintains homeostasis in cancer cell growth and survival. Therefore, the glucose analog 2-deoxyglucose (2DG) has been used as an anticancer reagent due to its inhibition of glycolysis. Prostate cancer cells (PC3) were treated with 2DG for 6 h or 48 h to analyze the changing of cell cycle and autophagic flux. Rapamycin and LC3B overexpressing vectors were administered to PC3 cells for autophagy induction and chloroquine and shBeclin1 plasmid were used to inhibit autophagy in PC3 cells to analyze PC3 cells growth and survival. The samples for western blotting were prepared in each culture condition to confirm the expression level of

immune Adenosine Deaminase 1226781-44-7, Rabbit Polyclonal to ZP4 Background Improved glycolysis is definitely a hallmark of cancer metabolism, yet relatively little is definitely known about this phenotype at premalignant stages of progression. a cell collection produced from a patient with early genetically stable Become; however, all cell lines keep active mitochondria. In response to the glycolytic inhibitor 2-deoxyglucose, the most glycolytic cell lines (CP-C and CP-D) experienced the very best suppression of extra-cellular acidification, but were able to compensate with upregulation of oxidative phosphorylation. In addition, these cell lines showed the least expensive compensatory raises in glycolysis in response to mitochondrial uncoupling by 2,4-dinitrophenol. Finally, these cell lines also upregulated their oxidative phosphorylation in response to glucose via the Crabtree effect, and demonstrate a higher range of modulation of air intake. A conclusion/Significance Our results recommend ...

Objective: 1, 5-anhydroglucitol (1,5-AG) is a short-term marker of metabolic control in diabetes. Its renal loss is stimulated in hyperglycemic conditions by glycosuria, which results in lowered plasma concentration. As low renal threshold for glucose has been described in HNF-1α MODY, 1,5-AG level may be altered in these patients. The purpose of this study was to assess the 1,5-AG levels in HNF-1α MODY patients and in type 2 diabetes (T2DM) subjects with a similar degree of metabolic control. In addition, we aimed to evaluate this particle as a biomarker for HNF-1α MODY.. Research Design and Methods: We included 33 diabetic patients from the Polish Nationwide Registry of MODY. In addition, we examined 43 T2DM patients and 47 non-diabetic controls. 1,5-AG concentration was measured with an enzymatic assay (GlycoMark). The ROC (receiver operation characteristic) analysis was utilized to evaluate 1,5-AG as a screening marker for HNF-1α MODY.. Results: The mean 1, 5-AG plasma concentration in ...

Aged rats (22 to 24 months) and young control rats (3 months) were tested in a battery of behavioral tests which included tests of learning, place navigation, sensorimotor integration, motor coordination, activity, and exploration. Following testing all animals were analyzed in an unanesthetized state for their local glucose utilization. Significant differences in glucose utilization were found between the aged and young groups on some behaviors and in some brain regions. There was considerable variability in the aged group in both their behavioral performance and their glucose utilization scores; thus, attempts were made to determine whether the variability in the degree of impairment within any particular behavioral test was correlated to the regional glucose utilization scores in any of the 45 brain regions analyzed. In two of the behavioral tests employed (i.e., one for learning and one for place navigation), the decline in performance correlated significantly with the decrement in regional ...

We studied regional cerebral glucose metabolism in 15 patients with a clinical diagnosis of corticobasal degeneration (CBD), 15 patients with probable Alzheimers disease (AD), and 15 healthy controls

Cerebral metabolic rate for glucose (CMRG) was measured using the 14C-deoxyglucose technique in a stroke model of the gerbil produced by bilateral common carotid artery occlusion. During 30 minutes of ischemia, 14C-deoxyglucose uptake in the brain was increased along the border zone between the ischemic and nonischemic area and decreased in the ischemic areas. During the early stage of reperfusion (2 or 3 to 30 minutes), CMRG increased 50 to 150% in the cerebral cortex, caudoputamen and thalamus and 270 to 320% in the hippocampus, globus pallidus and amygdala. During the late stage of reperfusion (15 to 45 minutes), heterogeneity of CMRG appeared in the cerebral cortex, caudoputamen and thalamus. CMRG decreased to less than 50% of the control value in the cerebral cortex but remained at 200 to 300% of control in the hippocampus, globus pallidus and amygdala. The latter structures exhibited a larger and more protracted increase in glucose metabolism than the other structures most probably due to ...

Fluorescent glucose biosensors are devices that measure the concentration of glucose in diabetic patients by means of sensitive protein that relays the concentration by means of fluorescence, an alternative to amperometric sension of glucose. No device has yet entered the medical market, but, due to the prevalence of diabetes, it is the prime drive in the construction of fluorescent biosensors. Keeping glucose levels in check is crucial to minimize the onset of the damage caused by diabetes. As a consequence, in conjunction with insulin administrations, the prime requirement for diabetic patients is to regularly monitor their blood glucose levels. The monitoring systems currently in general use have the drawback of below optimal number of readings, due to their reliance on a drop of fresh blood. Some continuous glucose monitors are commercially available, but suffer from the severe drawback of a short working life of the probe. The majority of these work amperometrically. As a result, there is ...

TY - JOUR. T1 - Tritiated 2‐deoxy‐D‐glucose. T2 - A high‐resolution marker for autoradiographic localization of brain metabolism. AU - Hammer, Ronald P.. AU - Herkenham, Miles. PY - 1984/1/1. Y1 - 1984/1/1. N2 - The technique for autoradiographic localization of 2‐deoxy‐D‐glucose (2DG) uptake has become a useful method for observing alterations of functional brain activity resulting from experimental manipulation. Autoradiographic resolution is improved using tritiated ([3H]) rather than carbon‐14 ([14C])2DG, due to the lower energy and shorter path of tritium emissions. In addition, lower 2DG uptake by white matter relative to gray matter is exaggerated in the [3H]2DG autoradiographs due to the greater absorption of tritium emissions by lipids. Using [3H]2DG, it is possible to observe differential metabolic labeling in various individual nuclei or portions of nuclei that is unresolvable using [14C]2DG in the awake, normal animal. Heterogeneous patterns of 2DG uptake seen only ...

[more ▼]. Objectives: To investigate whether the combination of fluoro-2-deoxy-D-glucose (FDG) PET measures with the APOE genotype would improve prediction of the conversion from mild cognitive impairment (MCI) to Alzheimer disease ( AD). Method: After 1 year, 8 of 37 patients with MCI converted to AD (22%). Differences in baseline regional glucose metabolic rate (rCMRglc) across groups were assessed on a voxel-based basis using a two-factor analysis of variance with outcome (converters [n = 8] vs nonconverters [n = 29]) and APOE genotype (E4 carriers [E4+] [n = 16] vs noncarriers [E4-] [n = 21]) as grouping factors. Results were considered significant at p , 0.05, corrected for multiple comparisons. Results: All converters showed reduced rCMRglc in ...

Neurofunctional Imaging of Plasticity in Mouse Somatic Sensory Cortex during Development and in Maturity: The color-coded images show energy metabolism in sections cut tangentially through the right cortical hemisphere. The quantitative autoradiographic deoxyglucose method was employed for neurofunctional imaging. Outlines of the barrels in somatic sensory cortex are superimposed on the images (The nose is to the right; the midline is up). When six whiskers, that is whiskers B1-3 and D1-3, on the left side were stimulated, focal regions of increased metabolic nerve cell activity (red) were found co-localized with the corresponding barrels B1-3 and D1-3 (top image; row A is outside the plane of section; the arrow points at barrel E1). The distinct gap of low activity between the highly activated regions comprises barrels C1-3. When the follicles of whiskers C1-3 were removed on the day of birth, the barrels that would have represented these whisker did not develop and the adjacent barrels ...

The carbon flux through the oxidative branch of the pentose phosphate pathway (PPP) can be viewed as an integrator of the antioxidant mechanisms via the generation of NADPH. It could therefore be used as a control point of the cellular response to an oxidative stress. Replacement of glucose by galactose sensitized the human epithelial cell line HGT-1 to H2O2 stress. Here we demonstrate that, due to the restricted galactose flux into the PPP, the H2O2 stress led to early cellular blebbing followed by cell necrosis, these changes being associated with a fall in the NADPH/NADP+ ratio and GSH depletion. H2O2 cytotoxicity was prevented by adding 2-deoxyglucose (2dGlc). This protection was associated with an increased flow of 2-deoxyglucose 6-phosphate into the oxidative branch of the PPP together with the prevention of the NADPH/NADP+ fall and the maintenance of intracellular GSH redox homoeostasis. Inhibitors of enzyme pathways connecting the PPP to GSH recycling abolished the 2dGlc protection. In ...

Glycolysis simply means the breakdown (lysis) of glucose and consists of a series of chemical reactions that are controlled by enzymes. How does glycolysis produce ATP? Important Facts about Glycolysis (cont. Glycolysis Inhibitors Upregulation of glycolysis with increase in glucose consumption for metabolic pathways to generate ATP is the universal property of all the cancers and tumors. 1 ATP, 3 NADH, and 1 FADH2 2 ATPs and 2 NADH 3 NADH and 1 FADH2 4 ATPs, 6 NADH, and 2 FADH2 Newtons second law states that force is equal to mass times acceleration: F = ma. Im aware that ultimately in the human body, after sugar is converted into pyruvate, then if fermentation happens it will be converted into lactate, or if aerobic respiration happens then it wont. ATP is created directly from glycolysis through the process of substrate-level phosphorylation (SLP) and indirectly by oxidative phosporylation (OP). Does Glycolysis produce lactate, or pyruvate? Something as complicated as cellular respiration ...

Sarcomas represent a diverse group of malignancies with distinct pathological and molecular features. and regular cells. Curiously, inhibitors of mitochondrial breathing do not really considerably impact viability, but had been capable to boost level of sensitivity of sarcomas to inhibition of glycolysis. Additionally, inhibition of glycolysis considerably decreased intracellular ATP amounts, and level of sensitivity to 2-DG-induced development inhibition was related to respiratory prices and glycolytic addiction. Our results demonstrate book human relationships between sarcoma bioenergetics and level of sensitivity to metabolic inhibitors, and recommend that inhibition of metabolic paths in sarcomas should become additional looked into as a potential restorative technique. < 0.05, indicating that WHI-P 154 IC50 cells that are more reliant on glycolysis possess WHI-P 154 IC50 lower ATP-linked respiration rates.

Introduction: Metabolic adaptations favor survival of cancer cells with higher glucose uptake. 2-Deoxy-glucose (2DG), a mimetic of glucose cannot undergo further glycolysis and hampers cell growth, essential during tumor metabolism. Chemotherapy with Cisplatin (Cis) and Pemetrexed (Pem) is the main treatment for malignant pleural mesothelioma (MPM). However, there is lack of evidence on the effects of 2DG in MPM.. Aim: To assess the synergistic effect of 2DG with Cis+Pem during cell migration in wound scratch assay.. Methods: Epithelioid (M14K), biphasic (MSTO) and sarcomatoid (ZL34) MPM cells were used in the study. Cells were grown into confluent monolayers and wounded. Wound widths were measured by microscopic imaging immediately and 8 hours after wound scratch in 10%FBS-RPMI (con), Cis(10μM)+Pem(200μM) or 2DG(3mM)+Cis+Pem. Statistical analyses were performed to assess cell migration.. Results: Migration with both treatments (Cis+Pem, 2DG+Cis+Pem) was significantly reduced compared to ...

In the present study, we have shown the antitumoral effect generated by the lis/lin/GO treatment. The linamarase/linamarin system induces cell death in a proportional manner to the linamarin concentration, destroying the entire cell culture in ∼96 to 120 hours. Cyanide mainly inhibits oxidative phosphorylation, the most important cellular source of energy. However, several studies had reported that the mitochondrial function is impaired in tumor cells, resulting in an elevated rate of glycolysis (30-32), which would circumvent the described therapy. In this context, we tried to combine lis/lin system with subtoxic amounts of the glycolysis inhibitor 3-bromo-pyruvate and we did not find any improvement of the therapy (data not shown). We have nevertheless investigated a combination that increases the system aggressiveness by combining a cyanide-inducing process with a nontoxic amount of GO that accelerates death by 48 hours. In the conditions we have used, GO advances cell death without causing ...

There are two main pathways of ATP biosynthesis: glycolysis and oxidative phosphorylation. As a rule, the two pathways are not fully active in a single cell. In this review, we discuss mechanisms of glycolytic inhibition of respiration (Warburg and Crabtree effects). What are the reasons for the existence of this negative feedback? It is known that maximal activation of both processes can cause generation of reactive oxygen species. Oxidative phosphorylation is more efficient from the energy point of view, while glycolysis is safer and favors biomass synthesis. This might be the reason why quiescent cells are mainly using oxidative phosphorylation, while the quickly proliferating ones - glycolysis ...
