A novel interaction mechanism accounting for different acylphosphatase effects on cardiac and fast twitch skeletal muscle sarcoplasmic reticulum calcium pumps. (1/8540)

In cardiac and skeletal muscle Ca2+ translocation from cytoplasm into sarcoplasmic reticulum (SR) is accomplished by different Ca2+-ATPases whose functioning involves the formation and decomposition of an acylphosphorylated phosphoenzyme intermediate (EP). In this study we found that acylphosphatase, an enzyme well represented in muscular tissues and which actively hydrolyzes EP, had different effects on heart (SERCA2a) and fast twitch skeletal muscle SR Ca2+-ATPase (SERCA1). With physiological acylphosphatase concentrations SERCA2a exhibited a parallel increase in the rates of both ATP hydrolysis and Ca2+ transport; in contrast, SERCA1 appeared to be uncoupled since the stimulation of ATP hydrolysis matched an inhibition of Ca2+ pump. These different effects probably depend on phospholamban, which is associated with SERCA2a but not SERCA1. Consistent with this view, the present study suggests that acylphosphatase-induced stimulation of SERCA2a, in addition to an enhanced EP hydrolysis, may be due to a displacement of phospholamban, thus to a removal of its inhibitory effect.  (+info)

In this study, we examined how cellular Ca2+ homeostasis is maintained in a vps33Delta vacuolar biogenesis mutant. We found that growth of the vps33Delta strain was sensitive to high or low extracellular Ca2+. This strain could not properly regulate cytosolic Ca2+ levels and was able to retain only a small fraction of its total cellular Ca2+ in a nonexchangeable intracellular pool. Surprisingly, the vps33Delta strain contained more total cellular Ca2+ than the wild type strain. Because most cellular Ca2+ is normally found within the vacuole, this suggested that other intracellular compartments compensated for the reduced capacity to store Ca2+ within the vacuole of this strain. To test this hypothesis, we examined the contribution of the Golgi-localized Ca2+ ATPase Pmr1p in the maintenance of cellular Ca2+ homeostasis. We found that a vps33Delta/pmr1Delta strain was hypersensitive to high extracellular Ca2+. In addition, certain combinations of mutations effecting both vacuolar and Golgi Ca2+ transport resulted in synthetic lethality. These results indicate that the Golgi apparatus plays a significant role in maintaining Ca2+ homeostasis when vacuolar biogenesis is compromised.  (+info)

Regulation of AMP deaminase from chicken erythrocytes. A kinetic study of the allosteric interactions. (3/8540)

The allosteric properties of AMP deaminase [EC] from chicken erythrocytes have been qualitatively and quantitatively accounted for by the concerted transition theory of Monod et al., on the assumption that this enzyme has different numbers of binding sites for each ligand. Theoretical curves yield a satisfactory fit for all experimental saturation functions with respect to activation by alkali metals and inhibition by Pi, assuming that the numbers of binding sites for AMP, alkali metals, and Pi are 4, 2, and 4, respectively. The enzyme was inhibited by concentrations of ATP and GTP below 0.1 and 0.25 mM, respectively, whereas activation of the enzyme was observed at ATP and GTP concentrations above 0.4 and 1.5 mM, respectively. These unusual kinetics with respect to ATP and GTP could be also accounted for by assuming 2 inhibitory and 4 activating sites for each ligand.  (+info)

Myocardial oxygenation during high work states in hearts with postinfarction remodeling. (4/8540)

BACKGROUND: Postinfarction left ventricular remodeling (LVR) is associated with reductions in myocardial high-energy phosphate (HEP) levels, which are more severe in animals that develop overt congestive heart failure (CHF). During high work states, further HEP loss occurs, which suggests demand-induced ischemia. This study tested the hypothesis that inadequate myocyte oxygen availability is the basis for these HEP abnormalities. METHODS AND RESULTS: Myocardial infarction was produced by left circumflex coronary artery ligation in swine. Studies were performed in 20 normal animals, 14 animals with compensated LVR, and 9 animals with CHF. Phosphocreatine (PCr)/ATP was determined with 31P NMR and deoxymyoglobin (Mb-delta) with 1H NMR in myocardium remote from the infarct. Basal PCr/ATP tended to be decreased in postinfarct hearts, and this was significant in animals with CHF. Infusion of dobutamine (20 microg x kg-1 x min-1 IV) caused doubling of the rate-pressure product in both normal and LVR hearts and resulted in comparable significant decreases of PCr/ATP in both groups. This decrease in PCr/ATP was not associated with detectable Mb-delta. In CHF hearts, rate-pressure product increased only 40% in response to dobutamine; this attenuated response also was not associated with detectable Mb-delta. CONCLUSIONS: Thus, the decrease of PCr/ATP during dobutamine infusion is not the result of insufficient myocardial oxygen availability. Furthermore, in CHF hearts, the low basal PCr/ATP and the attenuated response to dobutamine occurred in the absence of myocardial hypoxia, indicating that the HEP and contractile abnormalities were not the result of insufficient oxygen availability.  (+info)

Effects of phosphate intake on distribution of type II Na/Pi cotransporter mRNA in rat kidney. (5/8540)

BACKGROUND: Renal phosphate (Pi) reabsorption is regulated by dietary Pi intake, as well as in other ways. Changes in Pi reabsorption are associated with the modulation of sodium/Pi cotransporter type II (NaPi-2) protein abundance in the brush border membrane (BBM) of proximal tubules (PTs) and of renal NaPi-2 mRNA levels. In this study, we address whether the NaPi-2 protein and NaPi-2 mRNA distribution patterns in the renal cortex vary in parallel with changes of dietary Pi intake. METHODS: We investigated in cryosections of perfusion-fixed rat kidneys by in situ hybridization (ISH) and immunohistochemistry (IHC) the distribution patterns of NaPi-2 mRNA and of NaPi-2 protein one week, two hours, and four hours after changes in dietary Pi intake. RESULTS: NaPi-2 mRNA and NaPi-2 protein were present in PTs exclusively. In rats adapted to one week of high Pi intake, signals for NaPi-2 mRNA and NaPi-2 protein in cortical PTs were weak, except in the convoluted parts of PTs of juxtamedullary nephrons. After one week of low Pi intake, the ISH and IHC signals for NaPi-2 were high in PT segments in all cortical levels. The switch from a chronic high to a low Pi intake within two and four hours induced no increase and a slight increase, respectively, in the NaPi-2 mRNA signal in PTs of midcortical and of superficial nephrons, whereas in the BBM of these nephrons, NaPi-2 protein was markedly up-regulated. Two and four hours after switching from low to high Pi intake, the overall high ISH signal for NaPi-2 mRNA was unchanged, whereas NaPi-2 protein staining was drastically down-regulated in the BBM of PTs from superficial and midcortical nephrons. CONCLUSIONS: The marked changes in NaPi-2 protein abundance in the BBM, following altered dietary Pi intake, precede corresponding changes at the RNA level by several hours. Thus, the early adaptation to altered Pi intake involves mRNA-independent mechanisms. The up- or down-regulation of NaPi-2 protein abundance in the BBM and NaPi-2 mRNA in PT affects mainly midcortical and superficial nephrons.  (+info)

Biochemical indices of osteomalacia in pregnant Asian immigrants in Britain. (6/8540)

Serum calcium, phosphate and alkaline phosphatase, and urinary calcium excretion were examined during the second trimester of uncomplicated normal pregnancy in Asian immigrants to Britain and in local Caucasians. The mean serum calcium was significantly lower in Asians than in Caucasians, and the mean serum alkaline phosphatase was significantly higher in Asians. The geometric mean of the urinary calcium excretion was highly significantly lower in Asians than in Caucasians. The variances of the serum calcium, serum alkaline phosphatase, and urine calcium excretion did not differ significantly in the two populations. This indicates that there is a shift in values of immigrant Asians as a group compared with Caucasians. A comparison with figures obtained on normal nonpregnant persons of both suggests that the shift is not an inherent feature of the Asian population.  (+info)

Bound forms of Ca taken up by the synaptic plasma membrane. (7/8540)

Temperature dependent Ca-binding by the synaptic plasma membrane was increased in the presence of ATP and Mg++. Apparent Km for ATP was about 2.8 X 10(-5) M and optimal concentration of Mg++ was 2 mM in the presence of 2 mM ATP. After preincubation with nonradioactive Ca++, ATP and Mg++ to attain a steady state, addition of 45Ca resulted in remarkable labelling of the membrane, indicating rapid turnover of most of the membrane bound Ca. The presence of oxalate (60 mM) greatly increased Ca up-take on prolonged incubation. The Ca uptake in presence and absence of oxalate had similar substrate specificity and was similarly influenced by various monovalent cations. Furthermore, activities for Ca-uptake in the presence and absence of oxalate could not be separated by sucrose density gradient centrifugation of the synaptic plasma membrane fraction. Accordingly, it was considered that Ca++ in the medium was taken up by surface of the membrane, ATP- and temperature-dependently and then transferred into a cavity where the Ca-oxalate complex is formed.  (+info)

Mutations of Arg198 in sarcoplasmic reticulum Ca2+-ATPase cause inhibition of hydrolysis of the phosphoenzyme intermediate formed from inorganic phosphate. (8/8540)

Arg198 of sarcoplasmic reticulum Ca2+-ATPase was substituted with lysine, glutamine, glutamic acid, alanine, and isoleucine by site-directed mutagenesis. Kinetic analysis was performed with microsomal membranes isolated from COS-1 cells which were transfected with the mutated cDNAs. The rate of dephosphorylation of the ADP-insensitive phosphoenzyme was determined by first phosphorylating the Ca2+-ATPase with 32Pi and then diluting the sample with non-radioactive Pi. This rate was reduced substantially in the mutant R198Q, more strongly in the mutants R198A and R1981, and most strongly in the mutant R198E, but to a much lesser extent in R198K. The reduction in the rate of dephosphorylation was consistent with the observed decrease in the turnover rate of the Ca2+-ATPase accompanied by the steady-state accumulation of the ADP-insensitive phosphoenzyme formed from ATP. These results indicate that the positive charge and high hydrophilicity of Arg198 are critical for rapid hydrolysis of the ADP-insensitive phosphoenzyme.  (+info)

The specific activities of these enzymes and their electrophoretic mobilities on polyacrylamide in sodium dodecyl sulfate are the same. A limited tryptic digestion yields products with no change in the enzyme activity but with a reduction in the molecular weight of about 2000. Both low and high phosphate enzymes can be phosphorylated by the catalytic subunit of cAMP-dependent protein kinase, and approximately twice as much [32P]phosphate is incorporated into the low phosphate than the high phosphate enzyme. A comparison of their allosteric kinetic properties reveal that the high ...
BackgroundPlant adaptation to limited phosphate availability comprises a wide range of responses to conserve and remobilize internal phosphate sources and to enhance phosphate acquisition. Vigorous restructuring of root system architecture provides a developmental strategy for topsoil exploration and phosphate scavenging. Changes in external phosphate availability are locally sensed at root tips and adjust root growth by modulating cell expansion and cell division. The functionally interacting Arabidopsis genes, LOW PHOSPHATE RESPONSE 1 and 2 (LPR1/LPR2) and PHOSPHATE DEFICIENCY RESPONSE 2 (PDR2), are key components of root phosphate sensing. We recently demonstrated that the LOW PHOSPHATE RESPONSE 1 - PHOSPHATE DEFICIENCY RESPONSE 2 (LPR1-PDR2) module mediates apoplastic deposition of ferric iron (Fe3+) in the growing root tip during phosphate limitation. Iron deposition coincides with sites of reactive oxygen species generation and triggers cell wall thickening and callose accumulation, which ...

Phosphorus is an important macronutrient that is severely lacking in soils. In plants, specific microRNAs (miRNAs) essential for nutrient management and the regulation of stress responses are responsible for the control of many phosphate starvation responses. Further understanding of conserved and species-specific microRNA species has potential implications for the development of crops tolerant to soils with low phosphate. This study identified and characterised phosphate starvation-responsive miRNAs in the native Australian tobacco Nicotiana benthamiana. Small RNA libraries were constructed and sequenced from phosphate-starved plant leaves, stems and roots. Twenty-four conserved miRNA families and 36 species-specific miRNAs were identified. The majority of highly phosphate starvation-responsive miRNAs were highly conserved, comprising of members from the miR399, miR827, and miR2111 families. In addition, two miRNA-star species were identified to be phosphate starvation-responsive. A total of seven
A mutant of Arabidopsis thaliana deficient in the accumulation of inorganic phosphate has been isolated by screening directly for plants with altered quantities of total leaf phosphate. The mutant plants accumulate approximately 5% as much inorganic phosphate, and 24 to 44% as much total phosphate, as wild-type plants in aerial portions of the plant. Growth of the mutant is reduced, relative to wild type, and it exhibits other symptoms normally associated with phosphate deficiency. The phosphate deficiency is caused by a single nuclear recessive mutation at a locus designated pho1. The rate of phosphate uptake into the roots was similar between mutant and wild-type plants over a wide range of external phosphate concentrations. In contrast, when plants were grown in media containing 200 micromolar phosphate or less, phosphate transfer to the shoots of the mutant was reduced to 3 to 10% of the wild-type levels. The defect in phosphate transfer to the shoots could be overcome by providing higher ...
The effects of the Na+ gradient and pH on phosphate uptake were studied in brush-border membrane vesicles isolated from rat kidney cortex. The initial rates of Na(+)-dependent phosphate uptake were measured at pH 6.5, 7.5 and 8.5 in the presence of sodium gluconate. At a constant total phosphate concentration, the transport values at pH 7.5 and 8.5 were similar, but at pH 6.5 the influx was 31% of that at pH 7.5. However, when the concentration of bivalent phosphate was kept constant at all three pH values, the effect of pH was less pronounced; at pH 6.5, phosphate influx was 73% of that measured at pH 7.5. The Na(+)-dependent phosphate uptake was also influenced by a transmembrane pH difference; an outwardly directed H+ gradient stimulated the uptake by 48%, whereas an inwardly directed H+ gradient inhibited the uptake by 15%. Phosphate on the trans (intravesicular) side stimulated the Na(+)-gradient-dependent phosphate transport by 59%, 93% and 49%, and the Na(+)-gradient-independent phosphate ...
Low phosphate in the blood is linked to the risk of heart attack and coronary artery disease, a new study in the journal PLOS One reports. Researchers from the University of Surrey found that insufficient levels of phosphate in the blood may pose a particular danger to cardiovascular health, contradicting previous research in this area, which suggested low volumes of the mineral was beneficial to the heart. The study, using data from the RCGP Research and Surveillance Centre, examined phosphate levels of more than 100,000 patients, over five and nine-year intervals, and the impact on their cardiac health.

Renal reabsorption of inorganic phosphate (Pi) is mediated by the phosphate transporters NaPi-IIa, NaPi-IIc, and Pit-2 in the proximal tubule brush border membrane (BBM). Dietary Pi intake regulates these transporters; however, the contribution of the specific isoforms to the rapid and slow phase is not fully clarified. Moreover, the regulation of PTH and FGF23, two major phosphaturic hormones, during the adaptive phase has not been correlated. C57/BL6 and NaPi-IIa(-/-) mice received 5 days either 1.2 % (HPD) or 0.1 % (LPD) Pi-containing diets. Thereafter, some mice were acutely switched to LPD or HPD. Plasma Pi concentrations were similar under chronic diets, but lower when mice were acutely switched to LPD. Urinary Pi excretion was similar in C57/BL6 and NaPi-IIa(-/-) mice under HPD. During chronic LPD, NaPi-IIa(-/-) mice lost phosphate in urine compensated by higher intestinal Pi absorption. During the acute HPD-to-LPD switch, NaPi-IIa(-/-) mice exhibited a delayed decrease in urinary Pi ...

Phosphate starvation compromises electron flow through the cytochrome pathway of the mitochondrial electron transport chain, and plants commonly respond to phosphate deprivation by increasing flow through the alternative oxidase (AOX). To test whether this response is linked to the increase in nitric oxide (NO) production that also increases under phosphate starvation, Arabidopsis thaliana seedlings were grown for 15 d on media containing either 0 or 1mM inorganic phosphate. The effects of the phosphate supply on growth, the production of NO, respiration, the AOX level and the production of superoxide were compared for wild-type (WT) seedlings and the nitrate reductase double mutant nia. Phosphate deprivation increased NO production in WT roots, and the AOX level and the capacity of the alternative pathway to consume electrons in WT seedlings; whereas the same treatment failed to stimulate NO production and AOX expression in the nia mutant, and the plants had an altered growth phenotype. The NO donor S

Researchers at the University of Miami have identified a new marker to predict progressive kidney failure, death.. They have found that a high level of a hormone that regulates phosphate is associated with an increased risk of kidney failure and death among chronic kidney disease (CKD) patients.. Senior study author Myles Wolf, M.D., M.M.Sc., at the University of Miami, believes this discovery could lead to earlier diagnosis and treatment of phosphate problems.. Treatment typically consists of dietary phosphate restriction and phosphate binders - medications that work like a sponge to soak up phosphate in the gut.. Our bodies need phosphorus to build and repair bones and teeth, help cells function and maintain DNA. With fine-tuned regulation from hormones like FGF23, the kidneys help control the amount of phosphate in the blood by eliminating the excess.. Elevated phosphate levels are often a consequence of advanced kidney disease or damage. But too much phosphate may also make kidney disease ...
associated with effects on many organ systems as well. Because the complications of hyperphosphatemia are not even as predictable as those due to phosphate depletion, phosphate levels are typically described as elevated or severely elevated. Weakness, tetany, seizures, and dysrhythmias, including polymorphic ventricular tachycardia and torsades de pointes due to prolongation of the Q-T interval, can occur with hyperphosphatemia. These effects are not caused directly by the elevated phosphate, but are instead due to the resultant hypocalcemia. The reduction in ionized calcium can be demonstrated by the steady state reaction between calcium and phosphate. Hypomagnesemia, hypernatremia, and metabolic acidosis are also associated with hyperphosphatemia.. Treatment. Oral therapy is preferred over the IV route based on safety, no need for subsequent monitoring of electrolytes, and ease of administration. The plasma phosphate level peaks 1.5 h post ingestion, and typically rises 1 mg/dl for a 1g dose ...
Here, we present a new in situ microfluidic phosphate sensor that features an improved phosphate blue assay which includes polyvinylpyrrolidone in place of traditional surfactants-improving sensitivity and reducing temperature effects. The sensor features greater power economy and analytical performance relative to commercially available alternatives, with a mean power consumption of 1.8 W, a detection limit of 40 nM, a dynamic range of 0.14-10 μM, and an infield accuracy of 4 ± 4.5%. During field testing, the sensor was continuously deployed for 9 weeks in a chalk stream, revealing complex relations between flow rates and phosphate concentration that suggest changing dominance in phosphate sources. A distinct diel phosphorus signal was observed under low flow conditions, highlighting the ability of the sensor to decouple geochemical and biotic effects on phosphate dynamics in fluvial environments. This paper highlights the importance of high resolution in situ sensors in addressing the ...
We have developed methods that yield estimates of the 32P content of each of the individual phosphate groups of phosphatidylinositol 4-phosphate and phosphatidylinositol 4,5-bisphosphate, thus extending the information available from studies of the labelling of these lipids in intact cells or membrane preparations. The analyses are undertaken with the deacylated lipids. Assay of the 5-phosphate of phosphatidylinositol 4,5-bisphosphate is achieved by the use, under conditions of first-order kinetics, of a 5-phosphate-specific phosphomonoesterase present in isolated erythrocyte membranes [Downes, Mussat & Michell (1982) Biochem. J. 203, 169-177]. Assay of the 4-phosphate of phosphatidylinositol 4-phosphate and of the total monoester phosphate content (4-phosphate plus 5-phosphate) of phosphatidylinositol 4,5-bisphosphate employs alkaline phosphatase from bovine intestine. The radioactivity of the 1-phosphate is that remaining as organic phosphate after exhaustive alkaline phosphatase treatment. ...

It is found that phosphate sorption on TiO2 decreases with increasing pH, whereas the phosphate uptake by TiO2 increases with increasing ionic strength of the solution. In I≤0.1M, the sorption sharply increases and reaches a near maximum and then followed by little changes showing Langmuir-type behavior, whereas in I=0.7M, non-Langmuirian uptake becomes evident as equilibrium phosphate concentrations increase in solution. The sorption of phosphate on TiO2 is rapid and mostly irreversible at pH 4.5 and 7.0. At pH 9.0, however, the phosphate sorption is initially reversible and followed by resorption ...

Phosphorus In the body, almost all phosphorus is combined with oxygen to form phosphate. Phosphate is used as a building block for many substances such as DNA, cell membranes, etc. The body obtains phosphate from food and excretes it in urine and sometimes stool. Foods that are phosphate rich are milk, egg yolks, chocolate and soft drinks. Imbalances in phosphate may be too high (Hyperphosphatemia) or too low (Hypophosphatemia).. Instructions for Hyperphosphatemia. You have been diagnosed with hyperphosphatemia, which means you have too much phosphorus in your blood. Phosphorus helps develop bones and teeth and helps control energy metabolism. Most cases of hyperphosphatemia are caused by other health problems, such as kidney disease.. While in the hospital, you may have been treated with medicines for hyperphophatemia.. Diet changes. ...
TY - JOUR. T1 - Roles of phosphate and fibroblast growth factor 23 in cardiovascular disease. AU - Scialla, Julia J.. AU - Wolf, Myles. PY - 2014/4/1. Y1 - 2014/4/1. N2 - Disturbances in phosphate homeostasis are common in patients with chronic kidney disease. As kidney function declines, circulating concentrations of phosphate and the phosphate-regulatory hormone, fibroblast growth factor (FGF)-23, rise progressively. Higher serum levels of phosphate and FGF-23 are associated with an increased risk of adverse outcomes, including all-cause mortality and cardiovascular events. The associations between higher FGF-23 levels and adverse cardiovascular outcomes are generally independent of serum phosphate levels, and might be strongest for congestive heart failure. Higher serum phosphate levels are also modestly associated with an increased risk of cardiovascular events even after accounting for FGF-23 levels. This observation suggests that FGF-23 and phosphate might promote distinct mechanisms of ...
Phosphorus, acquired in the form of phosphate (Pi), is one of the primary macronutrients for plants but is least available in the soil. Pi deficiency is a major factor limiting plant growth, development and reproduction. Plants have developed a complex signaling network to respond to Pi deficiency. The recent discovery of strigolactones, a new class of plant hormones, has led to an emerging signaling module illustrating the integrated control of Pi acquisition, plant-microbe symbiotic interactions and plant architecture. This review article focuses on the recent findings of plant responses and roles of strigolactones to Pi deficiency.
Project approach and work plan:. Phase 1: In the week prior to the collection of standard pre-clinic blood work (to include calcium, phosphate, PTH), PD patients will keep a 3-day diary that will include all foods and beverages consumed in addition to the portion sizes. At the time of standard pre-clinic bloodwork collection, patients will perform an adequest. Medication lists will be reviewed for: 1) Proton pump inhibitors/ H2 receptor antagonists 2) 25-hydroxyvitamin D3 and 1,25 dihydroxyvitamin D3 and 3) phosphate binders. Doses taken the week prior to standard pre-clinic blood work when the diet diaries are compiled will be recorded. This information will be used for 2 separate purposes: 1) A list of the foods that are actually being eaten by the PD patients will be generated 2) The 3-day average phosphate content will be estimated from each PD patients food diaries. A regression equation that predicts serum phosphate concentration taking into account phosphate intake, the amount of ...

Phosphate-stress was determined in the monocot Zea mays. Definition of phosphate-stress was investigated by growing plants with and without phosphate in defined nutrient solution and measuring a number of parameters. These parameters included (1) measurements of shoot and root, (2) weight of shoot and root, (3) phosphatase activity present in the root, and (A) total phosphate levels of shoot and root. Conclusions of this study showed that phosphate-stressed corn had increased root growth, while shoot growth decreased. Not only were phosphate-starved roots longer, but they were less massive and less branching than phosphate-rich roots. Phosphatase secretion increased A-fold in roots starved for phosphate. Threshold for phosphate-stress has been determined to occur between 5uM and 15uM phosphate. The soluble phosphatase secreted from the root surface has been partially purified by ion-exchange chromatography. An acid and an alkaline phosphatase with pH optima 5.5 and 7.5, respectively, were ...

The soluble G protein, Gtr1, has previously been suggested to be involved in the derepressible Pho84 phosphate uptake function. This idea was based on a displayed deletion phenotype of Δgtr1 similar to the Δpho84 phenotype. As of yet, the mode of interaction has not been described. The consequences of a deletion of gtr1 on in vivo Pho84 expression, trafficking and activity, and extracellular phosphatase activity were analyzed in strains synthesizing either Pho84-green fluorescent protein or Pho84-myc chimeras. The studies revealed a delayed response in Pho84-mediated phosphate uptake and ...

In this study, we cloned and characterized a bHLH transcription factor, OsPTF1, which is responsible for tolerance to Pi starvation in rice. Overexpression of OsPTF1 can enhance tolerance to Pi deficiency. It was reported that PHO4, which was also a bHLH protein, acts as a key regulator of PHO regulon in yeast. In Pi starvation conditions, PHO4 combines with its partner, PHO2, and induces the expression of PHO5 and PHO84, the Pi starvation-induced acid phosphatase and the high-affinity Pi transporter (Johnston and Carlson, 1992; Oshima, 1997). Microarray analysis was performed to test whether OsPTF1 regulates downstream genes as PHO4. Unexpectedly, no high-affinity phosphate transporter genes or acid phosphatase genes were found to be controlled by OsPTF1 (see supplemental data). In addition, OsPTF1 is located in the nucleus in both high- and low-Pi conditions, which is different from PHO4, which is imported into or exported out of the nucleus under Pi-sufficient or starvation conditions (Kaman ...
The increase in the ratio of root growth to shoot growth that occurs in response to phosphate (Pi) deprivation is paralleled by a decrease in cytokinin levels under the same conditions. However, the role of cytokinin in the rescue system for Pi starvation remains largely unknown. We have isolated a gene from Arabidopsis thaliana (AtIPS1) that is induced by Pi starvation, and studied the effect of cytokinin on its expression in response to Pi deprivation. AtIPS1 belongs to the TPSI1/Mt4 family, the members of which are specifically induced by Pi starvation, and the RNAs of which contain only short, non-conserved open reading frames. Pi deprivation induces AtIPS1 expression in all cells of wild-type plants, whereas in the pho1 mutant grown on Pi-rich soils, AtIPS1 expression in the root was delimited by the endodermis. This supports the view that pho1 is impaired in xylem loading of Pi, and that long-distance signals controlling the Pi starvation responses act via negative control. Exogenous cytokinins

Maize (Zea mays) is not only a key human food and animal feed crop throughout the world but also an important raw material for the food industry and energy production plants [1]. Low phosphate concentrations are frequently a constraint for maize growth and development, and therefore, enormous quantities of phosphate fertilizer are expended in maize cultivation, which increases the cost of planting. Although the total amount of phosphorus (P) in the soil may be high, plants mainly absorb P in the inorganic form (Pi), which is present at a low concentration, limiting plant growth and development [2].. Phosphorus is an essential macronutrient for all living organisms and plays important roles in energy metabolism; biosynthesis of nucleic acids, phospholipids and membranes; cellular signal transduction and the regulation of many enzymes [3, 4]. Plants have evolved two broad strategies to cope with phosphate starvation, which involve changes in physiology, biochemistry and root morphology that ...

AU - Lee, Sang-Hyup. AU - Lee, Seunghak. AU - Choi, Jae Woo. PY - 2014. Y1 - 2014. N2 - To remove phosphate from solution, a new class of sorbent based on chitosan bead (CB) was prepared using copper ion (Cu(II)) with/without a traditional crosslinking agent (glutaraldehyde [GLA]); these materials are referred to as CB-G-Cu and CB-Cu, respectively. Copper ions play a key role in the CB synthesis; these species crosslink each polymer chain, and during phosphate removal, they are the active functional group. Overall, 2.5% (w/w) of chitosan is necessary to maintain the physical properties of the bead. In the FTIR spectra, adding GLA decreased the intensity of the amino group in chitosan, lowering the amount of copper in the CB. The maximum phosphate uptake (Q) for CB-Cu was 53.6 mg g-1 when calculated with the Langmuir ...
The mechanisms and regulation of intestinal phosphate absorption remain poorly defined. This is partly due to known species differences, as well as the variety of techniques and experimental conditions that have been used to assess phosphate absorption, particularly the wide range (and largely unphysiological choice) of phosphate concentrations added to uptake buffers. In the present study we have determined the luminal concentration of phosphate available for absorption, and we have used in vivo and in vitro methods to characterize the relative contributions of Na+‐dependent and Na+‐independent phosphate transport along the rat small and large intestine.. We have used the in vitro, everted sleeve technique developed by Karasov and Diamond (Karasov et al. 1983), and optimized by ourselves for the measurement of phosphate transport at the enterocyte BBM (Marks et al. 2007). Phosphate uptake was measured within the linear phase to ensure unidirectional flux, and that the isotope had not ...

Sucroferric oxyhydroxide (INN; trade name Velphoro, by Vifor Fresenius Medical Care Renal Pharma) is a non-calcium, iron-based phosphate binder used for the control of serum phosphorus levels in adult patients with chronic kidney disease (CKD) on haemodialysis (HD) or peritoneal dialysis (PD). It is used in form of chewable tablets. In a healthy person, normal serum phosphate levels are maintained by the regulation of dietary absorption, bone formation and resorption, equilibration with intracellular stores, and renal excretion. When kidney function is impaired, phosphate excretion declines. Without specific treatment, hyperphosphataemia occurs almost universally, despite dietary phosphate restriction and conventional dialysis treatment. In patients on dialysis, hyperphosphataemia is an independent risk factor for fractures, cardiovascular disease and mortality. Abnormalities in phosphate metabolism such as hyperphosphatemia are included in the definition of the new chronic kidney ...

DESCRIPTION (provided by applicant): In patients with chronic kidney disease (CKD), phosphate retention may contribute to progression of renal failure and is a major factor in the development of secondary hyperparathyroidism and vascular calcification. Progression of injury is causally associated with risk of mortality that is estimated 10 to 30 times higher for CKD patients undergoing dialysis than the general population. In fact, death is a more common outcome than dialysis or transplantation in patients with CKD. Phosphate binders are clinical mainstays in reducing dietary phosphate absorption and preventing hyperphosphatemia in the roughly 370,000 end-stage renal disease (ESRD) patients in the United States. While medicines exist that bind phosphorus effectively, all current forms of phosphate binder therapy are associated with very poor patient compliance due to a host of problems, including side effects that run the gamut of poor taste, halitosis, gastric bloating, constipation, the number ...
Hyperphosphatemia, that is, an abnormally high serum phosphate level, can result from increased phosphate (PO4) intake, decreased phosphate excretion, or a disorder that shifts intracellular phosphate to extracellular space. (See Pathophysiology, Etiology, Clinical Presentation, and Workup.
Introduction: Serum phosphate levels are insufficiently controlled in many patients with end-stage renal disease (ESRD), and novel therapeutic strategies are needed. Blocking intestinal phosphate absorption mediated by sodium-dependent phosphate co-transporter type 2b (NPT-IIb) holds promise; thus, we evaluated the efficacy, safety, tolerability, and pharmacokinetics of the novel and specific small molecule NPT-IIb inhibitor ASP3325 for the first time in humans. Methods: We conducted a randomized, double-blind, placebo-controlled, phase 1a single (n = 88) and multiple (n = 36) ascending dose study in healthy subjects, and a randomized, open-label, uncontrolled, phase 1b study in hyperphosphatemic ESRD patients on hemodialysis (single oral dose, n = 5; multiple oral doses, n = 17 ...
In order to determine the relation between depression of myocardial function and the myocardial high energy phosphate stores during acute hypoxia, a technique for serial evaluation of these stores was developed. Acute hypoxia was induced in 18 anesthetized dogs and serial determinations of adenosine triphosphate (ATP) and creatine phosphate (CP) were made while myocardial function was continuously measured. Myocardial concentrations of ATP were maintained even in the presence of severe hypoxia and myocardial failure. There was a small depression of the average myocardial CP concentration during early heart failure. However, in more than one-third of the dogs there was no significant depression of CP concentration at this time. It is concluded that hypoxic depression of myocardial function is not initiated by a decrease in the total myocardial high energy phosphate stores. The possibility could not be excluded that a particular fraction of the high energy phosphate store is decreased when ...

Microorganisms that release plant-available phosphate from natural soil phosphate stores may serve as biological alternatives to costly and environmentally damaging phosphate fertilizers. To explore this possibility, we engineered a collection of root bacteria to release plant available orthophosphate from phytate, an abundant phosphate source in many soils. We identified 82 phylogenetically diverse phytase genes, refactored their sequences for optimal expression in Proteobacteria, then synthesized and engineered them into the genomes of three root-colonizing bacteria. Liquid culture assays revealed 41 engineered strains with high levels of phytate hydrolysis. Among these, we identified 12 strains across three bacterial hosts that confer a growth advantage on the model plant Arabidopsis thaliana when phytate is the sole phosphate source. These data demonstrate that DNA synthesis approaches can be used to generate plant-associated strains with novel phosphate solubilizing capabilities.Importance ...
We report the synthesis of luminescent nanoparticles of manganese doped zinc sulfide (ZnS:Mn2+) with an emission peak at around 590 nm. Nanoparticles of ZnS:Mn2+ are prepared by a co-precipitation reaction from homogenous solutions of zinc and manganese salts. Based on Ostwald ripening and surface passivation, we discuss a mechanism for the formation of ZnS:Mn2+ nanoparticles. The reaction proceeds with the nucleation of ZnS crystals, which are immediately passivated by the anions in the solution. This in turn attracts cations including zinc and manganese which contribute to the growth of the crystal. These nanoparticles are sterically stabilized using polyphosphates of sodium namely sodium tripolyphosphate (STTP) and sodium hexametaphosphate (SHMP). The nanoparticles consist of particles of 60-80 nm in diameter, each containing primary crystallites that was estimated from the X-ray diffraction patterns to be at around 2.2 nm. ...

Genotypic variability in utilization of rock phosphates including the local source Eppawale was evaluated using Hevea clones during the early immature phase. All the clones responded to P fertilization, and the responces were related to the source of fertilizers and other soil characteristics. Plants of clone RR1C 121 utilized Eppawala rock phosphate efficiently, both in Matale and Boralu soil. But, plants of clone RR1C 110 were able to use both rock phosphate sources only in Matale soils. However, responce to rock phosphate from plants of 100 was comparatively low in relation to P uptake and dry matter production. The necessity of testing these clones for the locally available phosphate source in the field scale is also ...

Phosphate is a chemical compound that contains phosphorus and oxygen. It is necessary to the growth of plants and animals, and has extensive use as fertilizers. Phosphates are also used in the manufacture of detergents. In these products, phosphates help remove dirt and soften hard water. There are large amounts of natural phosphates. They occur in phosphate rocks, mostly combined with the elements calcium and magnesium. They also occur in the remains of animals(bone ash) and of plants (vegetable mold). Phosphate rock is the chief source of fertilizers containing phosphates. A soluble fertilizer known as superphosphate acts much more quickly than the pulverized rock. It is made by crushing the phosphate rock and treating it with sulfuric acid. Phosphorous is a chemical element that man, animals, and plants need for normal growth. Phosphorus is also used in the manufacture of many industrial products, such as plant fertilizers. Plants absorb phosphorus compounds from the soil, and human beings ...
ATP-binding cassette domain of the phosphate transport system. Phosphate uptake is of fundamental importance in the cell physiology of bacteria because phosphate is required as a nutrient. The Pst system of E. coli comprises four distinct subunits encoded by the pstS, pstA, pstB, and pstC genes. The PstS protein is a phosphate-binding protein located in the periplasmic space. PstA and PstC are hydrophobic and they form the transmembrane portion of the Pst system. PstB is the catalytic subunit, which couples the energy of ATP hydrolysis to the import of phosphate across cellular membranes through the Pst system, often referred as ABC-protein. PstB belongs to one of the largest superfamilies of proteins characterized by a highly conserved adenosine triphosphate (ATP) binding cassette (ABC), which is also a nucleotide binding domain (NBD). ...

Although some members of the major facilitator superfamily are known to play a role in transport into organelles, until now, transporters of the PiT and PHS families have not been found in organellar membranes. The initial clue to the location of PHT2;1 came from its long N-terminal extension, which is a feature unique to the plant members of the PiT family. In other transport families, extended N-terminal regions have been associated with regulation (Harper et al., 1998; Pittman and Hirschi, 2001), and Daram et al. (1999) proposed this function for PHT2;1 as well. However, computer predictions indicated that the N-terminal region probably was a transit peptide, and localization of a PHT2;1-GFP fusion protein confirmed that PHT2;1 resides in the chloroplast. The ChloroP 1.1 program predicted correctly a chloroplast localization for PHT2;1 and suggested a cleavage site between amino acids 71 and 72, which results in a transit peptide similar in length to those of the TPTs (Fischer et al., ...
