Mannose inhibits Arabidopsis germination via a hexokinase-mediated step. (1/363)

Low concentrations of the glucose (Glc) analog mannose (Man) inhibit germination of Arabidopsis seeds. Man is phosphorylated by hexokinase (HXK), but the absence of germination was not due to ATP or phosphate depletion. The addition of metabolizable sugars reversed the Man-mediated inhibition of germination. Carbohydrate-mediated regulation of gene expression involving a HXK-mediated pathway is known to be activated by Glc, Man, and other monosaccharides. Therefore, we investigated whether Man blocks germination through this system. By testing other Glc analogs, we found that 2-deoxyglucose, which, like Man, is phosphorylated by HXK, also blocked germination; no inhibition was observed with 6-deoxyglucose or 3-O-methylglucose, which are not substrates for HXK. Since these latter two sugars are taken up at a rate similar to that of Man, uptake is unlikely to be involved in the inhibition of germination. Furthermore, we show that mannoheptulose, a specific HXK inhibitor, restores germination of seeds grown in the presence of Man. We conclude that HXK is involved in the Man-mediated repression of germination of Arabidopsis seeds, possibly via energy depletion.  (+info)

Acute increase, stimulated by prostaglandin E2, in glucose absorption via the sodium dependent glucose transporter-1 in rat intestine. (2/363)

BACKGROUND/AIMS: Acute stimulation by cAMP of the sodium dependent glucose cotransporter SGLT1 has previously been shown. As prostaglandin E2 (PGE2) increases intracellular cAMP concentrations via its receptor subtypes EP2R and EP4R, it was investigated whether PGE2 could enhance intestinal glucose absorption. METHODS: The action of PGE2 on carbohydrate absorption in the ex situ perfused rat small intestine and on 3-O-[14C]methylglucose uptake in isolated villus tip enterocytes was determined. Expression of mRNA for the PGE2 receptor subtypes 1-4 was assayed in enterocytes by reverse transcriptase polymerase chain reaction (RT-PCR). RESULTS: In the perfused small intestine, PGE2 acutely increased absorption of glucose and galactose, but not fructose (which is not a substrate for SGLT1); in isolated enterocytes it stimulated 3-O-[14C]methylglucose uptake. The 3-O-[14C]methylglucose uptake could be inhibited by the cAMP antagonist RpcAMPS and the specific inhibitor of SGLT1, phlorizin. High levels of EP2R mRNA and EP4R mRNA were detected in villus tip enterocytes. CONCLUSION: PGE2 acutely increased glucose and galactose absorption by the small intestine via the SGLT1, with cAMP serving as the second messenger. PGE2 acted directly on the enterocytes, as the stimulation was still observed in isolated enterocytes and RT-PCR detected mRNA for the cAMP-increasing PGE2 receptors EP2R and EP4R.  (+info)

Muscle fiber type-specific defects in insulin signal transduction to glucose transport in diabetic GK rats. (3/363)

To determine whether defects in the insulin signal transduction pathway to glucose transport occur in a muscle fiber type-specific manner, post-receptor insulin-signaling events were assessed in oxidative (soleus) and glycolytic (extensor digitorum longus [EDL]) skeletal muscle from Wistar or diabetic GK rats. In soleus muscle from GK rats, maximal insulin-stimulated (120 nmol/l) glucose transport was significantly decreased, compared with that of Wistar rats. In EDL muscle from GK rats, maximal insulin-stimulated glucose transport was normal, while the submaximal response was reduced compared with that of Wistar rats. We next treated diabetic GK rats with phlorizin for 4 weeks to determine whether restoration of glycemia would lead to improved insulin signal transduction. Phlorizin treatment of GK rats resulted in full restoration of insulin-stimulated glucose transport in soleus and EDL muscle. In soleus muscle from GK rats, submaximal and maximal insulin-stimulated insulin receptor substrate (IRS)-1 tyrosine phosphorylation and IRS-1-associated phosphatidylinositol (PI) 3-kinase activity were markedly reduced, compared with that of Wistar rats, but only submaximal insulin-stimulated PI 3-kinase was restored after phlorizin treatment. In EDL muscle, insulin-stimulated IRS-1 tyrosine phosphorylation and IRS-1-associated PI-3 kinase were not altered between GK and Wistar rats. Maximal insulin-stimulated Akt (protein kinase B) kinase activity is decreased in soleus muscle from GK rats and restored upon normalization of glycemia (Krook et al., Diabetes 46:2100-2114, 1997). Here, we show that in EDL muscle from GK rats, maximal insulin-stimulated Akt kinase activity is also impaired and restored to Wistar rat levels after phlorizin treatment. In conclusion, functional defects in IRS-1 and PI 3-kinase in skeletal muscle from diabetic GK rats are fiber-type-specific, with alterations observed in oxidative, but not glycolytic, muscle. Furthermore, regardless of muscle fiber type, downstream steps to PI 3-kinase (i.e., Akt and glucose transport) are sensitive to changes in the level of glycemia.  (+info)

An inhibitor of p38 mitogen-activated protein kinase prevents insulin-stimulated glucose transport but not glucose transporter translocation in 3T3-L1 adipocytes and L6 myotubes. (4/363)

The precise mechanisms underlying insulin-stimulated glucose transport still require investigation. Here we assessed the effect of SB203580, an inhibitor of the p38 MAP kinase family, on insulin-stimulated glucose transport in 3T3-L1 adipocytes and L6 myotubes. We found that SB203580, but not its inactive analogue (SB202474), prevented insulin-stimulated glucose transport in both cell types with an IC50 similar to that for inhibition of p38 MAP kinase (0.6 microM). Basal glucose uptake was not affected. Moreover, SB203580 added only during the transport assay did not inhibit basal or insulin-stimulated transport. SB203580 did not inhibit insulin-stimulated translocation of the glucose transporters GLUT1 or GLUT4 in 3T3-L1 adipocytes as assessed by immunoblotting of subcellular fractions or by immunofluorescence of membrane lawns. L6 muscle cells expressing GLUT4 tagged on an extracellular domain with a Myc epitope (GLUT4myc) were used to assess the functional insertion of GLUT4 into the plasma membrane. SB203580 did not affect the insulin-induced gain in GLUT4myc exposure at the cell surface but largely reduced the stimulation of glucose uptake. SB203580 had no effect on insulin-dependent insulin receptor substrate-1 phosphorylation, association of the p85 subunit of phosphatidylinositol 3-kinase with insulin receptor substrate-1, nor on phosphatidylinositol 3-kinase, Akt1, Akt2, or Akt3 activities in 3T3-L1 adipocytes. In conclusion, in the presence of SB203580, insulin caused normal translocation and cell surface membrane insertion of glucose transporters without stimulating glucose transport. We propose that insulin stimulates two independent signals contributing to stimulation of glucose transport: phosphatidylinositol 3-kinase leads to glucose transporter translocation and a pathway involving p38 MAP kinase leads to activation of the recruited glucose transporter at the membrane.  (+info)

TGF-beta 1 stimulates glucose uptake by enhancing GLUT1 expression in mesangial cells. (5/363)

BACKGROUND: An increase in the expression of transforming growth factor-beta 1 (TGF-beta 1) has been proposed to play an important role in the excessive production of extracellular matrix (ECM) proteins seen in diabetes. Because the linkage between glucose metabolism and ECM protein production was found in mesangial cells overexpressed with the brain-type glucose transporter (GLUT1), we hypothesized that TGF-beta 1 could affect glucose metabolism. METHODS: To prove this hypothesis, we examined the effect of TGF-beta 1 on glucose uptake, the first step of glucose metabolism, in mesangial cells. 2-Deoxy-D-glucose (2DOG) uptake and the expression of GLUT1 were measured in mesangial cells exposed to various concentrations of TGF-beta 1. The kinetic constants were determined using 2DOG and 3-O-methyl-D-glucose (3OMG). The effect of anti-TGF-beta neutralizing antibody on 2DOG uptake and GLUT1 mRNA was also examined in mesangial cells cultured under high-glucose (22.2 mM) conditions for 72 hours. RESULTS: TGF-beta 1 stimulated 2DOG uptake in mesangial cells by approximately 2.5-fold in a dose- (1.25 ng/ml maximum) and time-dependent manner, with a peak stimulation at nine hours. The increase in 2DOG uptake by TGF-beta 1 was completely abolished by the addition of 1 microgram/ml cycloheximide, and kinetic analysis of 2DOG or 3OMG uptake revealed an increase in Vmax by TGF-beta 1. Furthermore, TGF-beta 1 enhanced the expression of GLUT1 mRNA from one hour, followed by an enhancement of the expression of GLUT1 protein at nine hours. Finally, 2DOG uptake was significantly enhanced in cells cultured under high-glucose (22.2 mM) conditions as compared with that in cells under normal glucose (5.6 mM) conditions, and this increase in 2DOG uptake in cells under high-glucose conditions was inhibited by the addition of anti-TGF-beta neutralizing antibody. CONCLUSIONS: TGF-beta 1 stimulates glucose uptake by enhancing the expression of GLUT1 in mesangial cells, which leads to the acceleration of intracellular metabolic abnormalities in diabetes.  (+info)

Characterization of cyclosporin A transport in cultured rabbit corneal epithelial cells: P-glycoprotein transport activity and binding to cyclophilin. (6/363)

PURPOSE: The purpose of this study was to characterize cyclosporin A (CsA) uptake and transport in cultured rabbit corneal epithelial cells (RCECs). METHODS: CsA uptake was evaluated by measuring time-dependent 3H-CsA accumulation in confluent RCECs. Bidirectional 3H-CsA fluxes were measured across the RCEC layers grown on Transwell-COL culture plate inserts. The anti-P-gp monoclonal antibody C219 was used in western blot analysis to probe for the presence of P-gp in these cells. RESULTS: The accumulation of 3H-CsA was time and temperature dependent. Steady state was reached by 60 minutes. The initial uptake was saturable and was suppressed as a function of increases in preloading with unlabeled CsA. This uptake process was enhanced by metabolic inhibition with either 3-O-methylglucose, MG, or 10 mM NaN3 and 3-O-MG. The largest increase was obtained with 10 mM NaN3 in combination with 3-O-MG. In their presence, uptake increased by 40%. A multidrug-resistance (MDR)-reversing agent (i.e., 500 microM verapamil, 100 microM vincristine, 100 microM progesterone, 100 microM testosterone, 500 microM quinidine, or 100 microM chlorpromazine) significantly increased 3H-CsA accumulation. The largest increase was obtained with 500 microM quinidine (i.e., 36%). Conversely, verapamil and vincristine produced the largest inhibition of 3H-CsA efflux (i.e., 19% and 28%, respectively). However, in the presence of 10 microM unlabeled CsA, 3H-CsA efflux increased. 3H-CsA flux across RCEC layers showed marked directional asymmetry. The stromal (S) to tear (T) side transcellular 3H-CsA permeability coefficient (Ptrans) was approximately seven times higher than that in the T-to-S direction. The S-to-T Ptrans was reduced by an MDR-reversing agent by up to 40%. Western blot analysis of lysates revealed a 170-kDa membrane protein band. CONCLUSIONS: These results suggest that in RCEC the tear-side-facing membrane has a P-gp-mediated drug efflux pump. In addition, there is suggestive evidence for the presence of the cytosolic protein, cyclophilin. The presence of P-gp in these cells could help protect them from being damaged by the uptake of toxic substances.  (+info)

In vitro analysis of the glucose-transport system in GLUT4-null skeletal muscle. (7/363)

We have characterized the glucose-transport system in soleus muscle from female GLUT4-null mice to determine whether GLUT1, 3 or 5 account for insulin-stimulated glucose-transport activity. Insulin increased 2-deoxyglucose uptake 2.8- and 2.1-fold in soleus muscle from wild-type and GLUT4-null mice, respectively. Cytochalasin B, an inhibitor of GLUT1- and GLUT4-mediated glucose transport, inhibited insulin-stimulated 2-deoxyglucose uptake by >95% in wild-type and GLUT4-null soleus muscle. Addition of 35 mM fructose to the incubation media was without effect on insulin-stimulated 3-O-methylglucose transport activity in soleus muscle from either genotype, whereas 35 mM glucose inhibited insulin-stimulated (20 nM) 3-O-methylglucose transport by 65% in wild-type and 99% in GLUT4-null mice. We utilized the 2-N-4-1-(1-azi-2,2,2-triflu oroethyl)benzoyl-1, 3-bis(D-mannose-4-yloxy)-2-propylamine (ATB-BMPA) exofacial photolabel to determine if increased cell-surface GLUT1 or GLUT4 content accounted for insulin-stimulated glucose transport in GLUT4-null muscle. In wild-type soleus muscle, cell-surface GLUT4 content was increased by 2.8-fold under insulin-stimulated conditions and this increase corresponded to the increase in 2-deoxyglucose uptake. No detectable cell-surface GLUT4 was observed in soleus muscle from female GLUT4-null mice under either basal or insulin-stimulated conditions. Basal cell-surface GLUT1 content was similar between wild-type and GLUT4-null mice, with no further increase noted in either genotype with insulin exposure. Neither GLUT3 nor GLUT5 appeared to account for insulin-stimulated glucose-transport activity in wild-type or GLUT4-null muscle. In conclusion, insulin-stimulated glucose-transport activity in female GLUT4-null soleus muscle is mediated by a facilitative transport process that is glucose- and cytochalasin B-inhibitable, but which is not labelled strongly by ATB-BMPA.  (+info)

Adipocyte insulin action following ovulation in polycystic ovarian syndrome. (8/363)

The role of anovulation and insulin resistance in the pathogenesis of polycystic ovarian syndrome (PCOS) remains to be determined. The aim of this study was to investigate whether the metabolic abnormality of insulin resistance in PCOS reflects, rather than causes, the ovarian dysfunction. Eight subjects with classical PCOS were studied on two occasions. Adipocyte insulin sensitivity together with hormonal and metabolic changes were investigated in patients with PCOS following prolonged amenorrhoea and then again in the early follicular phase after ovulation. Insulin receptor binding in amenorrhoeic subjects with PCOS was low at 0.78 +/- 0.08% and this increased to 1.18 +/- 0.19% after an ovulatory cycle (P < 0.05). Maximal insulin stimulated 3-O-methylglucose uptake was 0.70 +/- 0. 14 during amenorrhoea and increased to 1.08 +/- 0.25 pmol/10 cm(2) cell membrane (P < 0.05). Plasma testosterone fell (4.0 +/- 0.4 to 2. 3 +/- 0.2 nmol/l; P < 0.001), luteinizing hormone fell (17.6 +/- 2.3 to 6.7 +/- 0.8 IU/l; P < 0.001) but plasma insulin concentrations remained unchanged following ovulation (14.6 +/- 1.9 and 15.7 +/- 3. 8 pmol/l during amenorrhoea and after ovulation respectively). The results of this study suggest that chronic anovulation per se appears to modify the factors contributing to cellular insulin resistance seen in PCOS.  (+info)

3-O-Methylglucose: A non-metabolizable glucose analogue that is not phosphorylated by hexokinase. 3-O-Methylglucose is used as a marker to assess glucose transport by evaluating its uptake within various cells and organ systems. (J Neurochem 1993;60(4):1498-504)
Insulin stimulates glucose transport in isolated fat cells by activation of glucose transporters in the plasma membranes and through translocation of the glucose transporter sub-types GLUT4 (insulin-regulatable) and GLUT1 (HepG2 transporter). The protein kinase C-stimulating phorbol ester phorbol 12-myristate 13-acetate (PMA) is able to mimic partially the effect of insulin on glucose transport, apparently through stimulation of carrier translocation. In order to ascertain whether protein kinase C is involved in the translocation signal to both carrier sub-types, we determined the effect of PMA on the subcellular distribution of GLUT1 and GLUT4 by immunoblotting with specific antibodies directed against these transporters. Isolated rat fat cells (4 x 10(6) cells/ml) were stimulated for 20 min with insulin (6 nM) or PMA (1 nM). 3-O-Methylglucose transport was determined and plasma membranes and low-density microsomes were prepared for Western blotting. 3-O-Methylglucose transport was stimulated ...

The transport properties for phenylalanine and glucose in luminal-membrane vesicles from outer cortex (pars convoluta) and outer medulla (pars recta) of rabbit kidney were studied by a spectrophotometric method. Uptake of phenylalanine as well as of glucose by the two types of membrane vesicles was found to be Na+-dependent, electrogenic and stereospecific. Na+-dependent transport of L-phenylalanine by outer-cortical membrane vesicles could be accounted for by one transport system (KA congruent to 1.5 mM). By contrast, in the outer-medullary preparation, L-phenylalanine transport occurred via two transport systems, namely a high-affinity system with K1A congruent to 0.33 mM and a low-affinity system with K2A congruent to 7 mM respectively. Na+-dependent uptake of D-glucose by pars convoluta and pars recta membrane vesicles could be described by single, but different, transport systems, namely a low-affinity system with KA congruent to 3.5 mM and a high-affinity system with KA congruent to 0.30 ...
Glucose toxicity is a well-established entity that has been shown in animal models of diabetes to contribute to development of insulin resistance and impaired insulin secretion. In type II (non-insulin-dependent) diabetes in humans, a considerable body of evidence has accumulated indicating that a chronic physiological increment in the plasma glucose concentration leads to progressive impairment in insulin secretion and may contribute to insulin resistance as well. The precise biochemical mechanism(s) responsible for the hyperglycemia-induced defect in insulin secretion remains to be defined but may be related to a defect in phosphoinositide metabolism. In animal models of diabetes, development of insulin resistance is related to downregulation of the glucose-transport system, and a similar phenomenon is also likely to occur in humans. In addition, hyperglycemia in humans may lead to a defect in glycogen synthesis. In this respect, humans may be different from rats. In type I (insulin-dependent) ...
Downloadable! This paper uses Purchasing Power Parity (PPP) and Uncovered Interest Rate Parity (UIP) to estimate a time-varying equilibrium for the $NZ/$US nominal exchange rate over the period 1992 to 2003. While PPP is supported, the data does not support the strictest form of UIP. The estimated equilibrium can be considered a Behavioural Equilibrium Exchange Rate (BEER) that is conditional on interest rates and price levels. The large swings in New Zealands exchange rate during the 1990s were broadly consistent with the estimated conditional equilibrium, while the equally large swings in the exchange rate since 2000 were moves away from the conditional equilibrium. This may be because some factor other than interest rates or price levels has driven the exchange rate away from the conditional equilibrium since 2000. Alternatively, the long-run relationship between interest rates and the exchange rate may have changed since the 1990s.

It has been hypothesized on the basis of studies on BC3H-1 myocytes that diacylglycerol generation with activation of protein kinase C (PKC) is involved in the stimulation of glucose transport in muscle by insulin. In the present study, we used the rat epitrochlearis muscle to evaluate the possibility that PKC activity mediates the stimulation of glucose transport by insulin in mammalian skeletal muscle. Phospholipase C from Clostridium perfringens (PLC-Cp), which generates diacylglycerol from membrane phospholipids, and 4 beta-phorbol 12 beta-myristate 13 alpha-acetate (PMA) induced increases in glucose transport activity (assessed using 3-O-methylglucose transport) that were approximately 80 and approximately 20% as great, respectively, as that induced by a maximal insulin stimulus. PLC-Cp and PMA both caused a approximately 2-fold increase in membrane-associated PKC activity. In contrast, insulin did not affect PKC activity. These findings argue against a role of diacylglycerol-mediated PKC ...
To determine the role of insulin in reversing the insulin resistance associated with depletion of the intracellular pool of glucose transporters, streptozocin-induced diabetic rats were treated with 5 U/day s.c. of insulin for 0, 8, or 14 days. At each time point, adipose cells were isolated, and 3-O-methylglucose transport was measured in the absence and presence of 1000 μU/ml insulin. With the cytochalasin B-binding assay, concentrations of glucose transporters in the plasma and the low-density microsomal membrane fractions were determined. Eight-day insulin therapy enhanced glucose transport rate (mean ± SE) from 0.2 ± 0.0 to 1.1 ± 0.1 fmol · cell−1 · min−1 in the basal state and from 0.8 ± 0.1 to 5.5 ± 0.4 fmol · cell−1 · min−1 in the insulin-stimulated state in untreated and treated diabetic rats, respectively; this is a 3-fold increment of glucose transport rate in both states compared with control rats.

PURPOSE: To evaluate the ability of spin-lock imaging to detect the uptake of 3-o-methyl-D-glucose (3oMG) in normal brain and brain tumors in animals. METHODS: Measurements of the longitudinal relaxation rate in the rotating frame (R 1ρ ) were made over a range of spin-lock powers in rat brains bearing 9L tumors. The dispersion of R 1ρ values was quantified by ΔR 1ρ , the difference of R 1ρ values acquired with low and high locking powers. The glucose analogue 3oMG was administered intravenously and the differences of ΔR 1ρ values ( ΔR1ρdiff) before and as a function of time after administration were calculated to isolate the contribution of 3oMG to the dispersions, which at high fields primarily reflects chemical exchange effects ...

There is this one single real life friend of mine whom Ive told about fandom and shown one of my stories to (unless you count the sister, whom I sometimes forget is in fact a being separate from my own). The girl is everything I am not, with the shining exception of a few moments. She was in an up moment and I was in a down one, and it was the perfect time for us to meet because shes uplifting and I needed that. She bragged a new sexual experiment; she says I have that effect on her, to make her talk of sex (a statement I wont comment on, despite being terribly tempted :g:), which in all accuracy is not by any means on purpose. "I did something new and different that I had been meaning to do for a while," she said in those exact words, and by telepathy and a healthy weekly dose of slash porn I knew before the sentence was over what she had done. "its actually very, very good, and not what a girl generally expects of it" she continued, after some time of omg-how-did-you-know and ...

This study was designed to examine the effects of a high-fat refined-sugar (HFS) or a low-fat complex-carbohydrate (LFCC) diet on insulin-stimulated skeletal muscle glucose transport, plasma insulin, blood pressure, plasma triglycerides, plasma glycerol, body weight, and body fat in female Fischer rats. Insulin-stimulated glucose transport was significantly reduced in the HFS group at 2 wk, 2 mo, and 2 yr, whereas serum insulin was significantly elevated at all time points. Blood pressure was not significantly elevated in the HFS group until 12 mo, and all HFS animals were hypertensive by 18 mo. Glycerol, triglycerides, and abdominal fat cell size were not significantly different at 2 wk but were significantly elevated in the HFS rats at 2 and 6 mo. Body weight was similar in both groups until 20 wk on the diet, when the HFS rats started to gain more weight. These results demonstrate that insulin resistance and hyperinsulinemia occur before the other manifestations of the metabolic syndrome and ...
A protein of ~ 70-kDa was identified as a candidate Na +/Mg 2+ exchanger in rumen epithelial cells (REC). Melastatin-related Transient Receptor Potential 7 (TRPM7) and Magnesium Transporter 1 (MagT1) transcripts and, from them, encoded proteins were also detected. The regulation of these Mg transport pathways by extracellular [Mg] changes was the main focus of this study. Therefore, a 24-h pre-incubation of ovine REC in control (1.2 mM), low (0.12 mM)-Mg, and high (5 mM)-Mg medium was performed. Na +/Mg 2+ exchangers, TRPM7 and MagT1 abundance and activity were investigated by Western blot analysis, flow cytometry, immunocytochemistry and fluorescence spectroscopic measurements of [Mg 2+] i changes. Inhibitors were employed to differentiate Na +/Mg 2+ exchanger-mediated (imipramine) and channel-mediated (cobalt(III)hexaammine, nitrendipine) Mg transport. Basal [Mg 2+] i (0.40 ± 0.02 mM) was not influenced by pre-incubation in low- or high-Mg medium. However, compared with control REC (4.1 ± ...
Dehydroascorbate (DHA) competitively inhibits the uptake of 2-deoxy-D-glucose and of3-O-methyl-D-glucose by human blood neutrophils; 2-deoxyglucose and 3-0-methylglucose competitively inhibit dehydroascorbate uptake Ratios of Km to KI are near unity for each of these I gands. Exposure of cultured human fibroblasts to insulin enhances cytochalasin B-inhibitable uptake of DHA and of 2-deoxyglucose, both to the same degree.

PURPOSE: To characterize the properties of the glucose transporters of bovine retinal capillary endothelial cells and pericytes and to determine the effects of increased glucose concentrations on glucose transport activity. METHODS: Primary cultures of bovine retinal capillary endothelial cells and pericytes were exposed to low and high glucose concentrations, and immunoblot analysis, 14C-3-O-methylglucose transport activity, and cytochalasin B binding assays were used to characterize the glucose transporters. RESULTS: GLUT1, but not GLUT3 or GLUT4 transporter isoforms, was present in plasma membranes isolated from each cell type. The EC50 for glucose transport was similar in endothelial cells and pericytes (3.94 to 0.48 mM versus 2.24 to 0.69 mM) and was consistent with the EC50 previously reported for GLUT1 transporters on other cells, as was the observation that insulin did not acutely stimulate glucose transport in either cell type. The Vmax for glucose transport was greater in pericytes ...
Incubation of chicken embryo fibroblasts with mitogenic concentrations of insulin for 24 hr or with the tumor promoter phorbol 12-myristate 13-acetate for 6 hr stimulated lactate release and 3-O-methylglucose uptake. Insulin also increased the Vmax of 6-phosphofructo-1-kinase (ATP:D-fructose-6-phosphate 1-phosphotransferase, EC 2.7.1.11). Both agents increased the concentration of fructose 2,6-bisphosphate and the activity of 6-phosphofructo-2-kinase (EC 2.7.1.-), the enzyme that catalyzes the synthesis of this stimulator of 6-phosphofructo-1-kinase. These changes provide an explanation for the stimulation of glycolysis by insulin and phorbol esters. In contrast to the situation in rat liver, fructose 2,6-bisphosphate concentration did not decrease after cyclic AMP treatment. Incubation of cells with phorbol ester analogues or with glycerol derivatives that are known to stimulate, or to bind to, protein kinase C did increase the concentration of fructose 2,6-bisphosphate, suggesting that the ...
Calcium-tolerant myocytes from the adult rat heart were used to study the effects of insulin on the kinetics of myocardial 3-0-methylglucose transport at 37 degrees C. Insulin increased the initial velocity of sugar influx without affecting the equilibrium uptake values. Maximal stimulation averaged 50-80%, with a half-maximal response at an insulin concentration of 0.1 nM and maximal stimulation occurring at 1 nM. The onset of insulin action was preceded by a lag-phase of 20 s, reaching maximal action by 60 s. The Vmax. of the glucose transport system was increased from 160 to 287 nmol/min per 10(6) cells with an unaltered affinity. Neither extracellular nor intracellular calcium was found to be involved in the stimulatory action of insulin. Removal of intracellular magnesium resulted in a loss of insulin action. This study demonstrates that activation of the cardiac glucose transporter by insulin is due exclusively to an increase in the maximal velocity representing one of the very early effects of
Annes initial forays into mass spectrometry for glycopolymer analysis were stimulated in 1979 by a sabbatical visit to Imperial by Clint Ballou, Chair of Biochemistry at Berkeley. Together, they undertook pioneering work revising the structure of the 6-O-methylglucose polysaccharide of Mycobacterium smegmatis utilizing field desorption and fast-atom bombardment mass spectrometry. A few years later, her research on leukocyte glycosylation with Minoru Fukuda at the La Jolla Cancer Research Foundation was fundamental to the emerging field of glycobiology, laying foundations for studies into the roles of carbohydrates in the immune system. A seminal discovery was her identification of sialyl-Lewis X on neutrophils, pivotal to defining ligands for the selectins when they were cloned in 1989. Annes characterization of the glycoprotein hormone that controls erythropoiesis (erythropoietin) in the late 1980s was crucial for biopharmaceutical progress, as it provided the first evidence the recombinant ...

One time she hadnt eaten or drunk water in days and we thought she had come to the end. The vet was coming that afternoon to help her slip into the next life. I lay with her on our bed, sobbing on and off as one does, and after awhile Penny lifted her head and looked at me, jumped off the bed and headed to the toilet for a drink, then to the kitchen where she ate.

... Barnes B.R., T.C. Selix, D.C. Wright, and B.W. Craig. Ball State University, Muncie, IN.The purpose of this investigation was to determine the effects of a glucocorticoid-antagonist (RU486) on insulin-like-growth-factor-1 (IGF1)stimulated glucose transport following two weeks of hindlimb suspension (HS) on 100 gm male rats. After two weeks of HS and/or oral RU486 administration the animals were anesthetized, and the soleus (SOL) and extensor digitorum longus (EDL) muscles isolated and clamped at their resting length. Following an incubation series to prepare the muscle, the muscle was incubated in radioactive 3-O-methylglucose for 10 min. in the presence/absence of 75 ng/ml of IGF1, digested with 0.5 NaOH, and the amount of glucose transported measured. Two weeks of RU486 treatment significantly (P:5 0.05) elevated IGF1-stimulated glucose transport of SOL (0.576 ± 0.071 vs ...
Kaur D, Pham H, Larrouy-Maumus G, Rivière M, Vissa V, Guerin ME, Puzo G, Brennan PJ, Jackson Met al., 2009, Initiation of methylglucose lipopolysaccharide biosynthesis in mycobacteria., PLoS One, Vol: 4 BACKGROUND: Mycobacteria produce two unique families of cytoplasmic polymethylated polysaccharides -- the methylglucose lipopolysaccharides (MGLPs) and the methylmannose polysaccharides (MMPs) -- the physiological functions of which are still poorly defined. Towards defining the roles of these polysaccharides in mycobacterial physiology, we generated knock-out mutations of genes in their putative biosynthetic pathways. METHODOLOGY/PRINCIPAL FINDINGS: We report here on the characterization of the Rv1208 protein of Mycobacterium tuberculosis and its ortholog in Mycobacterium smegmatis (MSMEG_5084) as the enzymes responsible for the transfer of the first glucose residue of MGLPs. Disruption of MSMEG_5084 in M. smegmatis resulted in a dramatic decrease in MGLP synthesis directly attributable to the ...
The molecular and metabolic mechanisms underlying the increase in insulin sensitivity (i.e. increased insulin-stimulated skeletal muscle glucose uptake, phosphorylation and storage as glycogen) observed from 12 to 48 h following a single bout of exercise in humans remain unresolved. Moreover, whether these mechanisms differ with age is unclear. It is well established that a single bout of exercise increases the translocation of the glucose transporter, GLUT4, to the plasma membrane. Previous research using unilateral limb muscle contraction models in combination with hyperinsulinaemia has demonstrated that the increase in insulin sensitivity and glycogen synthesis 24 h after exercise is also associated with an increase in hexokinase II (HKII) mRNA and protein content, suggesting an increase in the capacity of the muscle to phosphorylate glucose and divert it towards glycogen synthesis ...
