The effect of chelating agents on iron mobilization in Chang cell cultures. (1/3854)

The investigation of chelating agents with potential therapeutic value in patients with transfusional iron overload has been facilitated by the use of Chang cell cultures. These cells have been incubated with [59Fe]transferrin for 22 hr, following which most of the intracellular radioiron is found in the cytosol, distributed between a ferritin and a nonferritin form. Iron release from the cells depends on transferrin saturation in the medium, but when transferrin is 100% saturated, which normally does not allow iron release, desferrioxamine, 2,3-dihydroxybenzoic acid, rhodotorulic acid, cholythydroxamic acid, and tropolone all promote the mobilization of ferritin iron and its release from cells. They are effective to an approximately equal degree. The incubation of [59Fe]transferrin with tropolone in vitro at a molar ratio of 1:500 results in the transfer of most of the labeled iron to the chelator, reflecting the exceptionally high binding constant of this compound. How far these phenomena relate to therapeutic potentially remains to be seen.  (+info)

Highly sensitive quantitation of methamphetamine by time-resolved fluoroimmunoassay using a new europium chelate as a label. (2/3854)

A simple and highly sensitive time-resolved fluoroimmunoassay of methamphetamine (MA) using a new fluorescent europium chelate (BHHCT-Eu3+) as a label is described. Two variations of competitive immunoassay were attempted. In the first (one-step) assay, microtiter plates coated with anti-MA were used, and the new label was bound to a conjugate of bovine serum albumin and N-(4-aminobutyl)-MA (MA-BSA). In the second (two-step) assay, instead of the labeled MA-BSA, biotinylated MA-BSA and BHHCT-Eu3+-labeled streptavidin-BSA were used. The lowest measurable concentrations of MA for the one-step and the two-step methods were 1 ng/mL (25 pg/assay) and 1 pg/mL (25 fg/assay), respectively. These were 10 to 1000 times superior to the detection limits of MA in any other immunoassay. Intra-assay coefficient of variation was approximately 2-8% at eight different concentrations (n = 4). Analysis of 34 urine samples with the new method and conventional gas chromatography showed a good correlation (r = 0.954). The high detectability of the present assay also enabled segmental hair analysis with a few centimeters of a hair.  (+info)

Plasticity of first-order sensory synapses: interactions between homosynaptic long-term potentiation and heterosynaptically evoked dopaminergic potentiation. (3/3854)

Persistent potentiations of the chemical and electrotonic components of the eighth nerve (NVIII) EPSP recorded in vivo in the goldfish reticulospinal neuron, the Mauthner cell, can be evoked by afferent tetanization or local dendritic application of an endogenous transmitter, dopamine (3-hydroxytyramine). These modifications are attributable to the activation of distinct intracellular kinase cascades. Although dopamine-evoked potentiation (DEP) is mediated by the cAMP-dependent protein kinase (PKA), tetanization most likely activates a Ca2+-dependent protein kinase via an increased intracellular Ca2+ concentration. We present evidence that the eighth nerve tetanus that induces LTP does not act by triggering dopamine release, because it is evoked in the presence of a broad spectrum of dopamine antagonists. To test for interactions between these pathways, we applied the potentiating paradigms sequentially. When dopamine was applied first, tetanization produced additional potentiation of the mixed synaptic response, but when the sequence was reversed, DEP was occluded, indicating that the synapses potentiated by the two procedures belong to the same or overlapping populations. Experiments were conducted to determine interactions between the underlying regulatory mechanisms and the level of their convergence. Inhibiting PKA does not impede tetanus-induced LTP, and chelating postsynaptic Ca2+ with BAPTA does not block DEP, indicating that the initial steps of the induction processes are independent. Pharmacological and voltage-clamp analyses indicate that the two pathways converge on functional AMPA/kainate receptors for the chemically mediated EPSP and gap junctions for the electrotonic component or at intermediaries common to both pathways. A cellular model incorporating these interactions is proposed on the basis of differential modulation of synaptic responses via receptor-protein phosphorylation.  (+info)

Hereditary juvenile haemochromatosis: a genetically heterogeneous life-threatening iron-storage disease. (4/3854)

Juvenile haemochromatosis is a rare inborn error of iron metabolism with clinical manifestations before 30 years of age. Unlike adult haemochromatosis which principally affects men, juvenile haemochromatosis affects the sexes equally; it causes early endocrine failure, dilated cardiomyopathy and joint disease. We report four patients (two of each sex) from three pedigrees affected by juvenile haemochromatosis with a mean onset at 22 years (range 14-30). All had endocrine deficiency with postpubertal gonadal failure secondary to pituitary disease; two suffered near-fatal cardiomyopathy with heart failure. Mean time to diagnosis from the first clinical signs of disease was 9.8 years (range 0.5-20) but general health and parameters of iron storage responded favourably to iron-depletion therapy. A 24-year-old man listed for heart transplantation because of cardiomyopathy [left ventricular (LV) ejection fraction 16%] responded to intravenous iron chelation with desferrioxamine combined with phlebotomy (ejection fraction 31%). A 27-year-old woman with subacute biventricular heart failure refractory to medication required orthotopic cardiac transplantation before the diagnosis was established (LV ejection fraction 25%). Genetic studies showed that these two patients with cardiomyopathy from unrelated families were heterozygous for the HFE 845G-->A (C282Y) mutation and wild-type at the H63D locus: complete sequencing of the intron-exon boundaries and entire coding sequence of the HFE gene failed to identify additional lesions. Two siblings in a pedigree without cardiomyopathy were wild-type at the HFE C282Y locus; although the brother harboured a single copy of the 187C-->G (H63D) allele, segregation analysis showed that in neither sibling was the iron-storage disease linked to MHC Class I markers on chromosome 6p. Juvenile haemochromatosis is thus a genetically heterogenous disorder distinct from the common adult variant.  (+info)

Similarities and differences in 111In- and 90Y-labeled 1B4M-DTPA antiTac monoclonal antibody distribution. (5/3854)

Monoclonal antibodies (MoAb) labeled with 90Y are being used for radioimmunotherapy. Because 90Y is a beta emitter, quantitative information from imaging is suboptimal. With the concept of a "matched pair" of isotopes, 111In is used as a surrogate markerfor90Y. We evaluated the differences in biodistribution between 111In- and 90Y-labeled murine antiTac MoAb directed against the IL-2Ralpha receptor. METHODS: The antiTac was conjugated to the 2-(4-isothiocyanatobenzyl)-6-methyl-diethylenetriamine pentaacetic acid (1B4M-DTPA, also known as MX-DTPA). Nine patients with adult T-cell leukemia were treated. Patients received approximately 185 MBq (5 mCi) 111In-labeled antiTac for imaging and 185-555 MBq (5-15 mCi) 90Y-labeled antiTac for therapy. The immunoreactivity of 111In-labeled antiTac was 90%+/-6%, whereas for 90Y-labeled antiTac, it was 74%+/-12%. RESULTS: The differences in blood and plasma kinetics of the two isotopes were small. The area undemeath the blood radioactivity curve was 1.91 percentage+/-0.58 percentage injected dose (%ID) x h/mL for 111In and 1.86%+/-0.64 %ID x h/mL for 90Y. Urinary excretion of 90Y was significantly greater than that of 111In in the first 24 h (P = 0.001), but later, the excretion of 111In was significantly greater (P = 0.001 to P = 0.04). Core biopsies of bone marrow showed a mean of 0.0029+/-0.0012 %ID/g for 111In, whereas the 90Y concentration was 0.0049+/-0.0021 %ID/g. Analyses of activity bound to circulating cells showed concentrations of 500-30,000 molecules of antiTac per cell. When cell-bound activity was corrected for immunoreactive fraction, the ratio of 111In to 90Y in circulating cells was 1.11+/-0.17. Three biopsies of tumor-involved skin showed ratios of 111In to 90Y of 0.7, 0.9 and 1.1. CONCLUSION: This study shows that differences typically ranging from 10% to 15% exist in the biodistribution between 111In- and 90Y-labeled antiTac. Thus, it appears that 111In can be used as a surrogate marker for 90Y when labeling antiTac with the 1 B4M chelate, although underestimates of the bone marrow radiation dose should be anticipated.  (+info)

Augmentation is a potentiation of the exocytotic process. (6/3854)

Short-term synaptic enhancement is caused by an increase in the probability with which synaptic terminals release transmitter in response to presynaptic action potentials. Since exocytosed vesicles are drawn from a readily releasable pool of packaged transmitter, enhancement must result either from an increase in the size of the pool or an elevation in the fraction of releasable vesicles that undergoes exocytosis with each action potential. We show here that at least one major component of enhancement, augmentation, is not caused by an increase in the size of the readily releasable pool but is instead associated with an increase in the efficiency with which action potentials induce the exocytosis of readily releasable vesicles.  (+info)

Receptor clearance obscures the magnitude of granulocyte-macrophage colony-stimulating factor responses in mice to endotoxin or local infections. (7/3854)

Marrow cells from mice lacking high-affinity receptors for granulocyte-macrophage colony-stimulating factor (GM-CSF; betac-/- mice) were shown to bind and internalize much less GM-CSF than cells from normal (betac+/+) mice. betac-/- mice were used to determine the effect of negligible receptor-mediated clearance on detectible GM-CSF responses to the intravenous injection of endotoxin or the intraperitoneal injection of casein plus microorganisms. Unlike the minor serum GM-CSF responses to endotoxin seen in betac+/+ mice, serum GM-CSF levels rose 30-fold to 9 ng/mL in betac-/- mice even though loss of GM-CSF in the urine was greater than in betac+/+ mice. Organs from betac-/- and betac+/+ mice had a similar capacity to produce GM-CSF in vitro, as did peritoneal cells from both types of mice when challenged in vitro by casein. However, when casein was injected intraperitoneally, betac-/- mice developed higher and more sustained levels of GM-CSF than did betac+/+ mice. The data indicated that receptor-dependent removal of GM-CSF masks the magnitude of GM-CSF responses to endotoxin and local infections. Because of this phenomenon, serum GM-CSF concentrations can be a misleading index of the occurrence or nonoccurrence of GM-CSF responses to infections.  (+info)

Selective induction of LTP and LTD by postsynaptic [Ca2+]i elevation. (8/3854)

Long-term potentiation (LTP) and long-term depression (LTD), two prominent forms of synaptic plasticity at glutamatergic afferents to CA1 hippocampal pyramidal cells, are both triggered by the elevation of postsynaptic intracellular calcium concentration ([Ca2+]i). To understand how one signaling molecule can be responsible for triggering two opposing forms of synaptic modulation, different postsynaptic [Ca2+]i elevation patterns were generated by a new caged calcium compound nitrophenyl-ethylene glycol-bis(beta-aminoethyl ether)-N,N,N',N'-tetraacetic acid in CA1 pyramidal cells. We found that specific patterns of [Ca2+]i elevation selectively activate LTP or LTD. In particular, only LTP was triggered by a brief increase of [Ca2+]i with relatively high magnitude, which mimics the [Ca2+]i rise during electrical stimulation typically used to induce LTP. In contrast, a prolonged modest rise of [Ca2+]i reliably induced LTD. An important implication of the results is that both the amplitude and the duration of an intracellular chemical signal can carry significant biological information.  (+info)

ABSTRACT Growth factors are thought to activate estrogen receptor-alpha ERα by phosphorylating the serines in the N-terminus of the receptor. However, this mechanism does not account for the conformational changes that occur in the ligand binding domain (LBD) of receptor to render the receptor active. It is hypothesized that epidermal growth factor (EGF) activates ERα through the PLC--calcium-calmodulin pathway by increasing intracellular calcium which, upon binding to the LBD, induces a conformational change that activates the receptor. In support of this hypothesis, treatment of MCF-7 cells with EGF (150 ng/ml) lead to an increase in intracellular calcium from 150 nM to 350 nM (+/-70 nM) and the induction of the ERα responsive genes, progesterone receptor (PgR) and pS2. The ability of EGF to induce PgR and pS2 mRNA was blocked by inhibitors of phospholipase C-, calmodulin, and calmodulin kinase II, the intracellular calcium chelator BAPTA-AM, and by an antiestrogen.

Human cytomegalovirus (HCMV)-encoded G protein-coupled-receptor US28 is believed to participate in virus dissemination through modulation of cell migration and immune evasion. US28 binds different CC chemokines and the CX3C chemokine CX3CL1. Membrane-anchored CX3CL1 is expressed by immune-activated endothelial cells, causing redirection of CX3CR1-expressing leukocytes in the blood to sites of infection. Here, we used stable transfected cell lines to examine how US28 expression affects cell migration on immobilized full-length CX3CL1, to model how HCMV-infected leukocytes interact with inflamed endothelium. We observed that US28-expressing cells migrated more than CX3CR1-expressing cells when adhering to immobilized CX3CL1. US28-induced migration was G protein-signalling dependent and was blocked by the phospholipase Cβ inhibitor U73122 and the intracellular calcium chelator BAPTA-AM. In addition, migration was inhibited in a dose-dependent manner by competition from CCL2 and CCL5, whereas CCL3 ...

Coordination complexes are so pervasive that their structures and reactions are described in many ways, sometimes confusingly. The atom within a ligand that is bonded to the central metal atom or ion is called the donor atom. In a typical complex, a metal ion is bonded to several donor atoms, which can be the same or different. A polydentate (multiple bonded) ligand is a molecule or ion that bonds to the central atom through several of the ligands atoms; ligands with 2, 3, 4 or even 6 bonds to the central atom are common. These complexes are called chelate complexes; the formation of such complexes is called chelation, complexation, and coordination. The central atom or ion, together with all ligands, comprise the coordination sphere.[5][6] The central atoms or ion and the donor atoms comprise the first coordination sphere. Coordination refers to the coordinate covalent bonds (dipolar bonds) between the ligands and the central atom. Originally, a complex implied a reversible association of ...

In the present study, we demonstrated that H2O2 modulates the relative levels of XO and XDH in endothelial cells via a pathway requiring ER calcium release. We also showed that ROS slowly released from Menadione and SIN-1 and stimulation of endogenous ROS using angiotensin II decreased the XDH content of endothelial cells in a manner similar to bolus H2O2. H2O2 evoked a progressive decline in XDH, and our metabolic labeling studies demonstrated that this was caused by conversion of XDH to XO. This conversion resulted in increased ROS production by XO as shown by ESR analysis. The effect of H2O2 was mediated by [Ca2+]i, because it was prevented by the calcium chelator BAPTA-AM and mimicked by the calcium ionophore A23187. Further, we demonstrated that H2O2 stimulated release of calcium from the ER, and that this was prevented by thapsigargin and the IP3 receptor antagonist 2-APB. The PLC activator m-3M3FBS mimicked the effect of H2O2, in keeping with the concept that PLC activation may be a ...
It is thought that selection determines which cells in a tissue give rise to a tumour through clonal expansion. Identifying biomarkers that detect this early precancerous process might enable prevention before tumours form. Based on findings that Flower protein marks pretumoral cells in Drosophila, Petrova et al. set out to study whether the mouse homologue (mFwe) has the same function. They show that mFwe expression is increased in skin cells surrounding papillomas in mice, and that mFwe-deficient mice develop normally but are resistant to chemically induced skin papillomas, suggesting that mFwe promotes the expansion of pretumoral cells. These data suggest that Flower protein might be a biomarker for early skin cancer detection and a potential drug target. Page 553. ...

The risk of coronary heart disease can be reduced by taking steps to prevent and control those adverse factors that put people at greater risk. Contact me to address potential risk factors such as poor diet and nutrition, hormone imbalance, toxic metal burden in the body, and to discuss the possibility of IV EDTA chelation for prevention and treatment ...
The appropriate dose of L-Glutathione depends on age, health and other conditions. Recommended dosage is 50mg taken daily with meals, or as directed by a physician. For adults only. Take with food. A physician should monitor use of LGlutathione to ensure adequate levels are achieved.. L-Glutathione is also recommended to be used in conjunction with heavy metal chelation to facilitate excretion rather than redepositing mobilized toxins. This is due to heavy metal chelation mobilizing toxins and overloading filtration organs (kidney, liver). When chelation occurs too quickly, toxins can be redeposited in different organs resulting in additional damage. ...
Collagen is a dominant protein in connective tissues and highly valuable in food industry. Fish processing byproducts are good alternative source for collagen. The objective of this study was to develop a simple non-toxic method to extract crude collagen from Yellowfin tuna skin and to check functional properties of its hydrolysates. Extraction procedures were conducted using acetic acid and citric acid with 0.5 M concentrations. Based on 8% SDS-PAGE gel, type I collagens were identified. Enzymatic hydrolysis was done with Protease, Trypsin and Pepsin enzymes with different time combinations (0 h, 3 h, 6 h, 9 h, 12 h and 24 h) at 37 °C after adjusting to its optimum pH level. Best hydrolysate was selected and subjected to antioxidant activity by Diphenyl-1-picryhydrazyl (DPPH) radical scavenging activity and Metal (Fe2+) chelating activity. Proximate analysis was conducted for raw skin to determine moisture, ash, crude protein, crude fat content and 59.44±0.013%, 1.91±0.37%, 28.55±1.19%, ...
Fig. 7 Activation of the P2X7 receptor on APCs by 3 μM ATP initiates the heightened immune responses associated with hypertension.. (A) Splenocytes from either C57BL/6 or P2X7 knockout mice were labeled with the Ca2+ probe Fluo-4 AM in vitro. The cells were then treated with either 3 or 500 μM ATP, and Ca2+ influx into DCs (left) and T cells (middle) was monitored continuously for 4 min by flow cytometry (right). The first minute kinetics of Ca2+ influx into DCs in the presence of 3 μM ATP is also shown. (B) Splenic DCs were stimulated with or without 3 μM ATP. Some of the ATP-treated cells were pretreated with the calcium chelator BAPTA or the calmodulin inhibitor chlorpromazine (Chlor). Surface CD86 was measured after 18 hours. (C) Peritoneal macrophages were treated with 3 or 500 μM ATP for 18 hours ex vivo, and IL-1β in the medium was measured by ELISA. Data were analyzed with paired Students t test. (D) Splenic DCs and T cells were purified from the spleen of naïve mice. DCs (2 × ...

EDTA chelation therapy is a nonsurgical treatment for heart disease. It can help you avoid heart and artery disease or could be an alternative to bypass surgery.
Copper(II) complexes of hexadentate ethylenediaminetetracarboxylic acid type ligands H4eda3p and H4eddadp (H4eda3p = ethylenediamine-N-acetic-N,N′,N′-tri-3-propionic acid; H4eddadp = ethylenediamine-N,N′-diacetic-N,N′-di-3-propionic acid) have been prepared. An octahedral trans(O6) geometry (two propionate ligands coordinated in axial positions) has been established crystallographically for the Ba[Cu(eda3p)]·8H2O compound, while Ba[Cu(eddadp)]·8H2O is proposed to adopt a trans(O5) geometry (two axial acetates) on the basis of density functional theory calculations and comparisons of IR and UV-vis spectral data. Experimental and computed structural data correlating similar copper(II) chelate complexes have been used to better understand the isomerism and departure from regular octahedral geometry within the series. The in-plane O-Cu-N chelate angles show the smallest deviation from the ideal octahedral value of 90°, and hence the lowest strain, for the eddadp complex with two ...

Copper-64 has been shown to dissociate from TETA and TETA-conjugates and to undergo transchelation to superoxide dismutase in rat liver in biodistribution and metabolism studies (7 , 20 , 21 , 27) . The cross-bridged cyclam, CB-TE2A, has demonstrated improved in vitro kinetic stability as well as a reduction of in vivo transchelation (25 , 27 , 38) . These studies suggest that CB-TE2A is an enhanced chelator compared with TETA for labeling 64Cu for in vivo imaging and therapy.. Similar binding affinities for SSTr prepared from AR42J tumor membranes were determined for 64Cu-TETA-Y3-TATE and 64Cu-CB-TE2A-Y3-TATE (Fig. 3)⇓ . However, there was a significant difference in the Bmax values measured for the TETA (192 fmol/mg) and CB-TE2A (1551 fmol/mg) conjugates. This might be attributed to a broader specificity for 64Cu-CB-TE2A-Y3-TATE binding to SSTr than for 64Cu-TETA-Y3-TATE. Although AR42J tumors express SSTr2, these tumor cells have also been shown to express SSTr1, SSTr3, and SSTr5 (31) . ...
