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. Treatment with ...

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 ...

Exposure to environmental and occupational toxicants is responsible for adverse effects on human health. Chelation therapy is the only procedure able to remove toxic metals from human organs and tissue, aiming to treat damage related to acute and/or chronic intoxication. The present review focuses on the most recent evidence of the successful use of the chelating agent ethylenediaminetetraacetic acid (EDTA). Assessment of toxic-metal presence in humans, as well as the rationale of EDTA therapy in cardiovascular and neurodegenerative diseases, is reported.
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 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.

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) . ...
