Abstract
Reduction and oxidation reactions are essential for biochemical processes. They are part of metabolic pathways and signal transduction. Reactive oxygen species (ROS) as second messengers and oxidative modifications of cysteinyl (Cys) residues are key to transduce and translate intracellular and intercellular signals. Dysregulation of cellular redox signaling is known as oxidative distress, which has been linked to various pathologies, including neurodegeneration. Alzheimer's disease (AD) is a neurodegenerative pathology linked to both, abnormal amyloid precursor protein (APP) processing, generating Aβ peptide, and Tau hyperphosphorylation and aggregation. Signs of oxidative distress in AD include: increase of ROS (H2O2, O2 •-), decrease of the levels or activities of antioxidant enzymes, abnormal oxidation of macromolecules related to elevated Aβ production, and changes in mitochondrial homeostasis linked to Tau phosphorylation. Interestingly, Cys residues present in APP form disulfide bonds that are important for intermolecular interactions and might be involved in the aggregation of Aβ. Moreover, two Cys residues in some Tau isoforms have been shown to be essential for Tau stabilization and its interaction with microtubules. Future research will show the complexities of Tau, its interactome, and the role that Cys residues play in the progression of AD. The specific modification of cysteinyl residues in redox signaling is also tightly connected to the regulation of various metabolic pathways. Many of these pathways have been found to be altered in AD, even at very early stages. In order to analyze the complex changes and underlying mechanisms, several AD models have been developed, including animal models, 2D and 3D cell culture, and ex-vivo studies of patient samples. The use of these models along with innovative, new redox analysis techniques are key to further understand the importance of the redox component in Alzheimer's disease and the identification of new therapeutic targets in the future.

Abstract
Alzheimer's disease (AD) is a type of neurodegenerative malady that is associated with the accumulation of amyloid plaques. Metal ions are critical for the development and upkeep of brain activity, but metal dyshomeostasis can contribute to the development of neurodegenerative diseases, including AD. This review highlights the association between metal dyshomeostasis and AD pathology, the feasibility of rebalancing metal homeostasis as a therapeutic strategy for AD, and a survey of current drugs that action via rebalancing metal homeostasis. Finally, we discuss the challenges that should be overcome by researchers in the future to enable the practical use of metal homeostasis rebalancing agents for clinical application.

Abstract
Designed metal ion binding peptides offer a variety of applications in both basic science as model systems of more complex metalloproteins, and in biotechnology, e.g. in bioremediation of toxic metal ions, biomining or as artificial enzymes. In this work a peptide (HS: Ac-SCHGDQGSDCSI-NH2) has been specifically designed for binding of both Zn(II) and Hg(II), i.e. metal ions with different preferences in terms of coordination number, coordination geometry, and to some extent ligand composition. It is demonstrated that HS accommodates both metal ions, and the first coordination sphere, metal ion exchange between peptides, and speciation are characterized as a function of pH using UV-absorption-, synchrotron radiation CD-, (1)H-NMR-, and PAC-spectroscopy as well as potentiometry. Hg(II) binds to the peptide with very high affinity in a {HgS2} coordination geometry, bringing together the two cysteinates close to each end of the peptide in a loop structure. Despite the high affinity, Hg(II) is kinetically labile, exchanging between peptides on the subsecond timescale, as indicated by line broadening in (1)H-NMR. The Zn(II)-HS system displays more complex speciation, involving monomeric species with coordinating cysteinates, histidine, and a solvent water molecule, as well as HS-Zn(II)-HS complexes. In summary, the HS peptide displays conformational flexibility, contains many typical metal ion binding groups, and is able to accommodate metal ions with different structural and ligand preferences with high affinity. As such, the HS peptide may be a scaffold offering binding of a variety of metal ions, and potentially serve for metal ion sequestration in biotechnological applications.

Abstract
Alzheimer's disease (AD) is a multifactorial neurodegenerative disease. It begins years prior to the onset of clinical symptoms, such as memory loss and cognitive decline. Pathological hallmarks of AD include the accumulation of β-amyloid in plaques and hyperphosphorylated tau in neurofibrillary tangles. Copper, iron, and zinc are abnormally accumulated and distributed in the aging brain. These metal ions can adversely contribute to the progression of AD. Dysregulation of cholesterol metabolism has also been implicated in the development of AD pathology. To date, large bodies of research have been carried out independently to elucidate the role of metals or cholesterol on AD pathology. Interestingly, metals and cholesterol affect parallel molecular and biochemical pathways involved in AD pathology. The possible links between metal dyshomeostasis and altered brain cholesterol metabolism in AD are reviewed.

Abstract
Speciation of the complexes of zinc(II) with a dodecapeptide (Ac-SCPGDQGSDCSI-NH2), inspired by the metal binding domain of MerR metalloregulatory proteins, have been studied by pH-potentiometric titrations, UV, SRCD (synchrotron radiation circular dichroism) and (1)H NMR experiments. (MerR is a family of transcriptional regulators the archetype of which is the Hg(2+)-responsive transcriptional repressor-activator MerR protein.) The aim of the ligand-design was to retain the advantageous metal binding features of MerR proteins in a model peptide for the efficient capture of toxic metal ions. The peptide binds zinc(II) via two deprotonated Cys-thiol groups and one of the Asp-carboxylates in the ZnL parent complex, possessing a remarkably high stability (logK=9.93). In spite of the relatively long peptide loop, bis-complexes are also formed with the metal ion under basic conditions. In a competition with cadmium(II) or mercury(II), zinc(II) cannot prevent the binding of toxic metal ions by the thiolate donor groups of the ligand. Around neutral pH one equivalent of mercury(II) was shown to fully replace zinc(II) from the ZnL species. Partial replacement of zinc(II) from the peptide by one equivalent of cadmium(II), relative to zinc(II) and the ligand, is also presumable, nevertheless, spectroscopic data may suggest the formation of mixed metal ion complexes, as well. Based on the obtained results the investigated dodecapeptide can be a promising candidate for capturing toxic metal ions in practical applications.

Abstract
Progressive deposition of amyloid beta (Aβ) peptides into amyloid plaques is the pathological hallmark of Alzheimer's disease (AD). The amyloid cascade hypothesis pins this deposition as the primary cause of the disease, but the mechanisms that causes this deposition remain elusive. An increasing amount of evidence shows that biometals Zn(II) and Cu(II) can interact with Aβ, thus influencing the fibrillization and toxicity. This review focuses on the role of Zn(II) and Cu(II) in AD, and revisits the amyloid cascade hypothesis demonstrating the possible roles of Zn(II) and Cu(II) in the disease pathogenesis.

Abstract
This tutorial review presents descriptions of two amyloidogenic proteins, amyloid-β (Aβ) peptides and islet amyloid polypeptide (IAPP), whose misfolding propensities are implicated in Alzheimer's disease (AD) and type II diabetes, respectively. Protein misfolding diseases share similarities, as well as some unique protein-specific traits, that could contribute to the initiation and/or development of their associated conditions. Aβ and IAPP are representative amyloidoses and are used to highlight some of the primary considerations for studying misfolded proteins associated with human diseases in this review. Among these factors, their physiological formation, aggregation, interactions with metal ions and other protein partners, and toxicity are presented. Small molecules that target and modulate the metal-Aβ interaction and neurotoxicity are included to illustrate one of the current approaches for uncovering the complexities of protein misfolding at the molecular level.

Abstract
There is an evolving field of metallobiology that has begun to describe a key role for bioavailable metals (particularly copper, zinc and iron) in the pathogenesis of Alzheimer’s disease (AD). In particular, there is an apparent failure in metal ion homeostasis, potentially caused by a pathological mislocalization of the metals in the brain, which appears to be an obligatory step in both the precipitation and potentiation of the disease. A number of both preclinical and clinical studies have also provided a strong burden of proof that normalizing metal ion homeostasis represents a valid therapeutic target, and may indeed represent the first disease-modifying strategy for AD. The role of metals in the pathophysiology of AD will be discussed in this article.

Abstract
Alzheimer disease (AD) is associated with extracellular deposition of proteolytic fragments of amyloid precursor protein (APP). Although mutations in APP and proteases that mediate its processing are known to result in familial, early onset forms of AD, the mechanisms underlying the more common sporadic, yet genetically complex forms of the disease are still unclear. Four single-nucleotide polymorphisms within the ubiquilin-1 gene have been shown to be genetically associated with AD, implicating its gene product in the pathogenesis of late onset AD. However, genetic linkage between ubiquilin-1 and AD has not been confirmed in studies examining different populations. Here we show that regardless of genotype, ubiquilin-1 protein levels are significantly decreased in late onset AD patient brains, suggesting that diminished ubiquilin function may be a common denominator in AD progression. Our interrogation of putative ubiquilin-1 activities based on sequence similarities to proteins involved in cellular quality control showed that ubiquilin-1 can be biochemically defined as a bona fide molecular chaperone and that this activity is capable of preventing the aggregation of amyloid precursor protein both in vitro and in live neurons. Furthermore, we show that reduced activity of ubiquilin-1 results in augmented production of pathogenic amyloid precursor protein fragments as well as increased neuronal death. Our results support the notion that ubiquilin-1 chaperone activity is necessary to regulate the production of APP and its fragments and that diminished ubiquilin-1 levels may contribute to AD pathogenesis.

Abstract
The amyloid precursor protein (APP) is the key player in Alzheimer's disease pathology, yet APP and its analogues are also essential for neuronal development and cell homeostasis in mammals. We have determined the crystal structure of the entire N-terminal APP-E1 domain consisting of the growth factor like and the copper binding domains at 2.7-A resolution and show that E1 functions as a rigid functional entity. The two subdomains interact tightly in a pH-dependent manner via an evolutionarily conserved interface area. Two E1 entities dimerize upon their interaction with heparin, requiring 8-12 sugar rings to form the heparin-bridged APP-E1 dimer in an endothermic and pH-dependent process that is characterized by a low micromolar dissociation constant. Limited proteolysis confirms that the heparin-bridged E1 dimers obtained in solution correspond to a dimer contact in our crystal, enabling us to model this heparin-[APP-E1](2) complex. Correspondingly, the APP-based signal transduction, cell-cell- and/or cell-ECM interaction should depend on dimerization induced by heparin, as well as on pH, arguing that APP could fulfill different functions depending on its (sub)cellular localization.

Electrospray ionization mass spectrometry was used to measure the binding of copper and nickel ions to the newly synthesized model peptides H(2)N-AAAAHAAAAHAAAAHAAAA-COOH (P19-H5) and H(2)N-AAAHAAAHAAAHAAAAAAA-COOH (P19-H4). The affinity of histidine-containing peptides toward heavy metal ions proved to be related to the position of each histidine residue in the peptide sequence. In contrast to P19-H5, P19-H4 peptide bound no nickel or copper ions in the gas phase, whereas its spectra showed an intense fragmentation. The role of spacing residues (Ala repeats) in selecting the various conformations was also investigated. Finally, the circular dichroism and Fourier transform infrared spectra indicated that these isomer peptides have quite different conformations. A close relationship between the conformation of alanine-based peptides and their affinity toward metal ions may result in different patterns of metal ion-peptide systems.

Interaction of beta-amyloid(1-40) peptide with pairs of metal ions: An electrospray ion trap mass spectrometric model study. Biophys Chem 2009; 144:9-20. [PMID: 19539421 DOI: 10.1016/j.bpc.2009.05.008] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2009] [Revised: 05/22/2009] [Accepted: 05/27/2009] [Indexed: 02/04/2023]
Abstract
The stoichiometries and the affinity toward simple and paired metal ions of synthetic amyloid-beta(1-40) peptide (Abeta1-40) were investigated by electrospray ion trap mass spectrometry (ESI-MS), circular dichroism (CD), and atomic force microscopy (AFM). The results lead to the working hypothesis that pH-dependent metal binding to Abeta1-40 may induce conformational changes, which affect the affinity toward other metals. A significant copper and zinc binding to Abeta1-40 peptide at pH 5.5 was found, whereas nickel ions commonly bind to each molecule of beta-amyloid peptide. Some complexes of Abeta1-40 with more than one nickel ion were identified by ESI-MS. In addition, nickel ions proved to enhance Abeta oligomerization. On increasing pH, up to 12 ions of zinc may bind to a single Abeta molecule. Under the same pH and concentration conditions, the binding pattern of the independent copper and silver ions to Abeta1-40 was different from that of the equimolecular mixture of the two metal ions. One might assume that some conformational changes due to water loss altered the capacity of Abeta peptide to bind certain heavy metal ions. As a consequence, copper-silver interaction with the binding process to Abeta1-40 became highly complex. A competition between silver and nickel ions for Abeta1-40 binding sites at high pH was also observed. New strategies were proposed to identify the characteristic signals for some important metal ion-peptide complexes in the spectra recorded at high pH or high concentrations of metal ions. To explain the formation of such a large number of high metal ion-Abeta complexes, we took into consideration the participation of both histidine residues and free amino groups as well as carboxylate ones in the binding process. Finally, CD and AFM studies supported the mass spectrometric data.

Abstract
Iron and other metal ions appear to play an important role in protein aggregation and are therefore likely to provide a link between protein aggregation and oxidative damage. This work reports on iron binding to amyloid- beta peptide (Abeta1-40), which affords a very specific electrospray ionization mass spectrometric (MS) spectrum. Both MS and MS/MS study confirmed that amyloid-beta peptide displays a high affinity toward iron(III) ions, producing multi charged molecular ions and peptide aggregates. Finally, the circular dichroism spectra indicate an unexpected modification of Abeta1-40 peptide conformation upon iron binding.

Abstract
PICK1 (protein interacting with Ckinase 1) containing a PDZ domain, a BAR domain, and two short acidic regions is as an adaptor protein that plays an important role in alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid receptor trafficking, cell morphology and migration, as well as in some diseases such as cancer, schizophrenia and pain. To better understand the physiological function of PICK1, we expressed the recombinant PICK1 and its truncated mutants in E.coli, and measured their zinc binding properties by fluorescence and competition assay. It is shown that PICK1 has one Zn2+-binding site. The Zn2+-binding properties of PICK1 are not appreciably affected after the removal of BARC domain (involving BAR domain and C-terminal acidic region). Deleting the N-terminal acidic region of NPDZ domain (involving PDZ domain and N-terminal acidic region) in PICK1 impairs its Zn2+-binding capacity. The mutation of the CPC (Cys-Pro-Cys) motif in the PDZ domain of PICK1 abolishes the ability of Zn2+-binding. In addition, Zn2+ can enhance the lipid-binding ability of PDZ domain as observed in both protein-lipid overlay assay and fluorescence analysis. The results presented in this report suggested that Zn2+ plays a regulatory role in the trafficking of PICK1 from the cytoplasm to cell membrane.

Abstract
The amyloid precursor protein (APP) is a transmembrane protein that plays major roles in the regulation of several important cellular functions, especially in the nervous system, where it is involved in synaptogenesis and synaptic plasticity. The secreted extracellular domain of APP, sAPPalpha, acts as a growth factor for many types of cells and promotes neuritogenesis in post-mitotic neurons. Alternative proteolytic processing of APP releases potentially neurotoxic species, including the amyloid-beta (Abeta) peptide that is centrally implicated in the pathogenesis of Alzheimer's disease (AD). Reinforcing this biochemical link to neuronal dysfunction and neurodegeneration, APP is also genetically linked to AD. In this review, we discuss the biological functions of APP in the context of tissue morphogenesis and restructuring, where APP appears to play significant roles both as a contact receptor and as a diffusible factor. Structural investigation of APP, which is necessary for a deeper understanding of its roles at a molecular level, has also been advancing rapidly. We summarize recent progress in the determination of the structure of isolated APP fragments and of the conformations of full-length sAPPalpha, in both monomeric and dimeric states. The potential role of APP dimerization for the regulation of its biological functions is also discussed.

Abstract
Current research suggests that imbalances in metal-ion homeostasis play a critical role in neurodegenerative disorders, such as Alzheimer's disease and transmissible spongiform encephalopathy, and in cancer. It is thus important to elucidate the mechanisms by which homeostasis is maintained and how metals function in cellular processes, including cell signaling, neurotransmission, and protein transport and storage. This summary of a meeting recently held in Barcelona, Spain, highlights some of the latest findings on intra- and extracellular zinc signaling, the consequences of zinc imbalances on cells and on the brain, the mechanisms of metal-ion influx and efflux, how metal ions are sequestered by metallothioneins, and the development of candidate drugs to treat brain injury due to metal-ion imbalances.

Abstract
Aggregation of the human peptide amyloid-beta (Abeta) is a key event in Alzheimer's disease (AD). Zinc ions play an important role in AD and in Abeta aggregation. In vitro, Zn(II) binds to Abeta and accelerates its aggregation. In this work we have investigated Zn(II) binding to the synthetic peptide Abeta1-16, which contains the metal-binding domain of Abeta. Cd(II) was used to probe the Zn(II) site. Abeta1-16 bound one equivalent of Zn(II) with an apparent dissociation constant (Kd) of 10(-4) M. This Kd value is in the same range as the Zn concentration needed to precipitate Abeta. Circular dichroism and NMR indicated predominantly random-coil secondary structures of apo-Abeta1-16, Zn(II)-Abeta1-16 and Cd(II)-Abeta1-16, which were all highly dynamic and flexible. The three histidines at positions 6, 13 and 14 were suggested to be ligands to Zn(II) and Cd(II). Evidence that the aspartate at position 1 served as a fourth ligand to Zn(II) and Cd(II) was found at pH 8.7. 111Cd(II) NMR showed a resonance at 84 ppm, in line with a mixed oxygen-/nitrogen-ligand environment. The tyrosine at position 10 could be excluded as a ligand.
