  • [Show abstract] [Hide abstract] ABSTRACT: Background: Several studies suggest that pathological changes in Alzheimer's disease (AD) brain begin around 10-20 years before the onset of cognitive impairment. Biomarkers that can support early diagnosis and predict development of dementia would, therefore, be crucial for patient care and evaluation of drug efficacy. Although cerebrospinal fluid (CSF) levels of Aβ42, tau, and p-tau are well-established diagnostic biomarkers of AD, there is an urgent need to identify additional molecular alterations of neuronal function that can be evaluated at the systemic level. Objectives: This study was focused on the analysis of oxidative stress-related modifications of the CSF proteome, from subjects with AD and amnestic mild cognitive impairment (aMCI). Methods: A targeted proteomics approach has been employed to discover novel CSF biomarkers that can augment the diagnostic and prognostic accuracy of current leading CSF biomarkers. CSF samples from aMCI, AD and control individuals (CTR) were collected and analyzed using a combined redox proteomics approach to identify the specific oxidatively modified proteins in AD and aMCI compared with controls. Results: The majority of carbonylated proteins identified by redox proteomics are found early in the progression of AD, i.e., oxidatively modified CSF proteins were already present in aMCI compared with controls and remain oxidized in AD, thus suggesting that dysfunction of selected proteins initiate many years before severe dementia is diagnosed. Conclusions: The above findings highlight the presence of early oxidative damage in aMCI before clinical dementia of AD is manifested. The identification of early markers of AD that may be detected peripherally may open new prospective for biomarker studies.

  • [Show abstract] [Hide abstract] ABSTRACT: Alzheimer disease (AD) is the most common form of dementia among the elderly and is characterized by progressive loss of memory and cognition. Amyloid-ß-peptide (Aß) forms senile plaques, which, together with hyperphosphorylated tau-based neurofibrillary tangles, are the hallmarks of AD neuropathology. Evidence support the involvement of immune system in AD progression and current concepts regarding its pathogenesis include the participation of inflammatory and autoimmune components in the neurodegenerative process. Pathologically, immune system components have been detected in the brain, cerebrospinal fluid (CSF) and in serum of AD subjects and their trend of variation correlates with disease progression. However, patients with AD present significantly lower levels of antibody immunoreactivity against Aß in serum and CSF than healthy controls suggesting that a depletion of such patrolling system is involved in the deposition of toxic aggregates in AD. Within this frame, incomplete and often controversial results are reported about CNS immune/ autoimmune responses during AD, and a better comprehension of such processes is needed. Our research will aim to shed light on the nature and potential role of autoantibodies in CSF and serum from AD and amnestic mild cognitive impairment (aMCI) patients compared to healthy subjects by using an immunoproteomics approach. Our method allows recognition of natural occurring antibodies by the identification of brain antigen targeted by human IgGs. Overall our data reveal that the alterations of autoantibodies profile both in CSF and serum follow disease staging and progression. However, we demonstrate a fair overlap between CSF and serum suggesting the existence of different immunogenic events. Interestingly, CSF autoantibodies recognized, among others, key players of energy metabolic pathway, including glycolysis and TCA cycle, found oxidatively modified in AD brain studies. These data suggest a potential casual sequence between oxidative damage at brain level, autoantibodies presence in CSF and reduced energy metabolism of AD patients.

    [Show abstract] [Hide abstract] ABSTRACT: Rosemary (Rosmarinus officinalis L.) has been used since ancient times in traditional medicine, while nowadays various rosemary formulations are increasingly exploited by alternative medicine to cure or prevent a wide range of health disorders. Rosemary's bioproperties have prompted scientific investigation, which allowed us to ascertain antioxidant, anti-inflammatory, cytostatic, and cytotoxic activities of crude extracts or of pure components. Although there is a growing body of experimental work, information about rosemary's anticancer properties, such as chemoprotective or anti-proliferative effects on cancer cells, is very poor, especially concerning the mechanism of action. Melanoma is a skin tumor whose diffusion is rapidly increasing in the world and whose malignancy is reinforced by its high resistance to cytotoxic agents; hence the availability of new cytotoxic drugs would be very helpful to improve melanoma prognosis. Here we report on the effect of a rosemary hydroalcoholic extract on the viability of the human melanoma A375 cell line. Main components of rosemary extract were identified by liquid chromatography coupled to tandem mass spectrometry (LC/ESI-MS/MS) and the effect of the crude extract or of pure components on the proliferation of cancer cells was tested by MTT and Trypan blue assays. The effect on cell cycle was investigated by using flow cytometry, and the alteration of the cellular redox state was evaluated by intracellular ROS levels and protein carbonylation analysis. Furthermore, in order to get information about the molecular mechanisms of cytotoxicity, a comparative proteomic investigation was performed.

  • [Show abstract] [Hide abstract] ABSTRACT: A common feature of non-coding repeat expansion disorders is the accumulation of RNA repeats as RNA foci in the nucleus and/or cytoplasm of affected cells. These RNA foci can be toxic by sequestering RNA-binding proteins, thus affecting various steps of post-transcriptional gene regulation. However, the precise step that is affected by C9orf72 GGGGCC (G4C2) repeat expansion, the major genetic cause of Amyotrophic Lateral Sclerosis, is still poorly defined. In this work, we set out to characterise these mechanisms by identifying C9orf72 RNA binding proteins. Sequestration of some of these factors into RNA foci was observed when a (G4C2)31 repeat was expressed in NSC34 and HeLa cells. Most notably, (G4C2)31 repeats widely affected the distribution of Pur-alpha and its binding partner FMRP, which accumulate in intra-cytosolic granules that are positive for stress granules markers. Accordingly, translational repression is induced. Interestingly, this effect is associated to a marked accumulation of poly(A) mRNAs in cell nuclei. Thus, defective trafficking of mRNA, as a consequence of impaired nuclear mRNA export, might affect translation efficiency and contribute to the pathogenesis of C9orf72 ALS.

    [Show abstract] [Hide abstract] ABSTRACT: Microglia are resident macrophages in the central nervous system, whose participation against exogenous injuries and infections is mainly marked by an immediate release of inflammatory cytokines along with a toxic efflux of superoxide radicals. Indeed, many lines of evidence indicate that persistent activation of these cells turns their neuroprotective phenotype into a neurotoxic one, which contributes to destroy neuronal activity and induces neuronal loss in several neurodegeneration processes, such as Alzheimer's disease. In this study we attempted to fill-in the gap in our knowledge about redox regulation of amyloid activated microglia. With this aim, we carried out a robust and comprehensive characterization of the reversibly redox modified proteome both at the level of resting and amyloid-activated BV2 cells, an immortalised cell line of murine microglia. The approach we used combined the selective enrichment of reversible redox modified proteins through a biotin bait with nanoscale liquid chromatography tandem mass spectrometry of their proteolytic peptides. By this reliable approach, we identified 60 proteins changing the redox status of their selective cysteine residues upon treatment with the amyloidogenic Aβ25-35 peptide. These results assessed that in microglia stimulated by amyloids, redox modifications of the proteome specifically target proteins involved in crucial cell processes, i.e. those involved in the protein synthesis. In particular, for peroxiredoxin-6 (Prdx6) and Ras-related C3 botulinum toxin substrate 1 (Rac1) we suggest mechanisms through which reversible redox modifications could affect the peculiar role of microglia in amyloidogenic injury, which at the same time reinforce the oxidative burst and resist toward it. Moreover, the redox modulation we observed on chloride intracellular channel protein 1 (CLIC1) strengthens the structural and functional relationship between the oxidative stress and the metamorphic transition of this protein from a soluble form to an integral membrane form. The redox signatures we determined might also provide neurologists with more specific and reliable biomarkers to distinguish the diverse microglia status in neurodegeneration and then to drive targeted drug design.

  • [Show abstract] [Hide abstract] ABSTRACT: Microglia are macrophages within the central nervous system playing a central role in neurodegenerative disorders. Although the initial engagement of microglia seems to be neuroprotective, many lines of evidence indicate that its persistent activation contributes to dismantle neuronal activity and to induce neuronal loss. The molecular pathways that lead from amyloid interaction with membrane receptors to the microglial activation have been extensively investigated, although a definitive picture is not yet at hand. In this work, primary and immortalised microglial cells were treated with a synthetic form of Aß peptides, and relative abundance of acetylated and phosphorylated STAT3 were assayed. Results highlight, for the first time, three distinctive sequential events: i) an earlier event marked by the increase in the level of STAT3 acetylated species, followed by ii) a later increase in the level of STAT3 phosphorylated form, and finally iii) an involvement of phosphorylated STAT3 in the increase in expression of the 14-3-3 epsilon, a protein frequently associated with neurodegenerative diseases and known to be a marker of Aß-activated microglia. These data outline a complex, time-dependent modification of STAT3 signalling triggered by amyloid in the microglial compartments, that once confirmated by in vivo experiments will broad knowledge of the molecular basis of amyloid neurotoxicity.

    [Show abstract] [Hide abstract] ABSTRACT: Creutzfeldt–Jakob disease (CJD) is a neurodegenerative disorder characterized by the deposition of the pathological conformer (PrPCJD) of the host encoded cellular prion protein (PrPC). In genetic CJD associated with V210I or R208H PrP substitutions, the pathogenic role of mutant residues is still poorly understood. To understand how V210I or R208H PrP mutations facilitate the development of the disease, we determined by mass spectrometry the quantitative ratio of mutant/wild-type PrPCJD allotypes in brains from affected subjects. We found that the mutant PrPCJD allotypes moderately exceeds of 2- or 3-fold the amount of the wild-type counterpart suggesting that these mutations mainly exert their pathogenic effect on the onset of the pathogenic cascade.

  • [Show abstract] [Hide abstract] ABSTRACT: Down syndrome (DS) is the most common genetic cause of intellectual disability, due to partial or complete triplication of chromosome 21. DS subjects are characterized by a number of abnormalities including premature aging and development of Alzheimer's disease (AD) neuropathology after approximately 40 years of age. Several studies show that oxidative stress plays a crucial role in the development of neurodegeneration in DS population. Increased lipid peroxidation is one of the main events causing redox imbalance within cells through the formation of toxic aldehydes that easily react with DNA, lipids and proteins. In this study we used a redox proteomics approach to identify specific targets of 4-hydroxynonenal modifications in the frontal cortex from DS cases, with and without AD pathology. We suggest that a group of identified proteins followed a specific pattern of oxidation in DS vs. young controls (CTRY), likely indicating characteristic features of DS phenotype; a second group of identified proteins showed increased oxidation in DS/AD vs. DS, thus possibly playing a role in the development of AD. The third group of comparison, DS/AD vs. old controls (CTRO), identified proteins that may be considered specific markers of AD pathology. All the identified proteins are involved in important biological functions including intracellular quality control systems, cytoskeleton network, energy metabolism and antioxidant response. Our results demonstrate that oxidative damage is an early event in DS, as well as dysfunctions of protein degradation systems and cellular protective pathways, suggesting that DS subjects are more vulnerable to oxidative damage accumulation that might contribute to AD development. Further, considering that the majority of proteins have been already demonstrated to be oxidized in AD brain, our results strongly support similarities with AD in DS.

    [Show abstract] [Hide abstract] ABSTRACT: The development of plant root systems is characterized by a high plasticity, made possible by the continual propagation of new meristems. Root architecture is fundamental for overall plant growth, abiotic stress resistance, nutrient uptake and response to environmental changes. Understanding the function of genes and proteins which control root architecture and/or stress resistance will contribute to develop more sustainable systems of intensified crop production. To meet these challenges, proteomics provides the genome-wide scale characterization of protein expression pattern, subcellular localization, post-translational modifications, activity regulation and molecular interactions. In this review, we describe a variety of proteomic strategies that have been applied to study the proteome of the whole organ and of specific cell-types during root development. Each has advantages and limitations, but collectively they are providing important insights into the mechanisms by which auxin structures and patterns the root system, and on the interplay between signaling networks, auxin transport and growth. The acquisition of proteomic, transcriptomic and metabolomic datasets of the root apex on the cell scale has revealed the high spatial complexity of regulatory networks, and fosters the use of new powerful proteomic tools for a full understanding of the control of root developmental processes and environmental responses.

    [Show abstract] [Hide abstract] ABSTRACT: Multiple sclerosis (MS) is an autoimmune inflammatory demyelinating disease of the central nervous system. Several evidences suggest that MS can be considered a multi-factorial disease in which both genetics and environmental factors are involved. Among proposed candidates, growing results support the involvement of oxidative stress (OS) in MS pathology. The aim of this study was to investigate the role of OS in event of exacerbations in MS on serum of relapsing-remitting (RR-MS) patients, either in relapsing or remitting phase, with respect to serum from healthy subjects. We applied proteomics and redox proteomics approaches to identify differently expressed and oxidatively modified proteins in the low-abundant serum protein fraction. Among differently expressed proteins ceruloplasmin, antithrombin III, clusterin, apolipoprotein E, and complement C3, were up-regulated in MS patients compared with healthy controls. Further by redox proteomics, vitamin D-binding protein showed a progressive trend of oxidation from remission to relapse, respect with controls. Similarly, the increase of oxidation of apolipoprotein A-IV confirmed that levels of OS are elevated with the progression of the disease. Our findings support the involvement of OS in MS and suggest that dysfunction of target proteins occurs upon oxidative damage and correlates with the pathology.

    [Show abstract] [Hide abstract] ABSTRACT: DS is the most frequent genetic cause of intellectual disability characterized by the anomalous presence of three copies of chromosome 21. One of the peculiar features of DS is the onset of Alzheimer's disease neuropathology after the age of 40 years characterized by deposition of senile plaques and neurofibrillary tangles. Growing studies demonstrated that increased oxidative damage, accumulation of unfolded/damaged protein aggregates and dysfunction of intracellular degradative system are key players in neurodegenerative processes. In this study, redox proteomics approach was used to analyze the frontal cortex from DS subjects under the age of 40 compared with age-matched controls, and proteins found to be increasingly carbonylated were identified. Interestingly, our results showed that oxidative damage targets specifically different components of the intracellular quality control system such as GRP78, UCH-L1, V0-ATPase, cathepsin D and GFAP that couples with decreased activity of the proteasome and autophagosome formation observed. We also reported a slight but consistent increase of Aß 1-42 SDS- and PBS-soluble form and tau phosphorylation in DS versus CTR. We suggest that disturbance in the proteostasis network could contribute to the accumulation of protein aggregates, such as amyloid deposits and NFTs, which occur very early in DS. It is likely that a sub-optimal functioning of degradative systems occur in DS neurons, which in turn provide the basis for further accumulation of toxic protein aggregates. The results of this study suggest that oxidation of protein members of the proteostatis network is an early event in DS and might contribute to neurodegenerative phenomena.

    [Show abstract] [Hide abstract] ABSTRACT: The pathological form of prion protein (PrPSc), as other amyloidogenic proteins, causes a marked increase of membrane permeability. PrPSc extracted from infected Syrian hamster brains induces a considerable change in membrane ionic conductance, although the contribution of this interaction to the molecular mechanism of neurodegeneration process is still controversial. We previously showed that the human PrP fragment 90–231 (hPrP90–231) increases ionic conductance across artificial lipid bilayer, in a calcium-dependent manner, producing an alteration similar to that observed for PrPSc. In the present study we demonstrate that hPrP90–231, pre-incubated with 10 mM Ca++ and then re-suspended in physiological external solution increases not only membrane conductance but neurotoxicity as well. Furthermore we show the existence of a direct link between these two effects as demonstrated by a highly statistically significant correlation in several experimental conditions. A similar correlation between increased membrane conductance and cell degeneration has been observed assaying hPrP90–231 bearing pathogenic mutations (D202N and E200K). We also report that Ca++ binding to hPrP90–231 induces a conformational change based on an alteration of secondary structure characterized by loss of alpha-helix content causing hydrophobic amino acid exposure and proteinase K resistance. These features, either acquired after controlled thermal denaturation or induced by D202N and E200K mutations were previously identified as responsible for hPrP90–231 cytotoxicity. Finally, by in silico structural analysis, we propose that Ca++ binding to hPrP90–231 modifies amino acid orientation, in the same way induced by E200K mutation, thus suggesting a pathway for the structural alterations responsible of PrP neurotoxicity.

    [Show abstract] [Hide abstract] ABSTRACT: Failure in cytokinesis, the final step in cell division, by generating tetra- and polyploidization promotes chromosomal instability, a hallmark of cancer. Here we show that HIPK2, a kinase involved in cell fate decisions in development and response to stress, controls cytokinesis and prevents tetraploidization through its effects on histone H2B. HIPK2 binds and phosphorylates histone H2B at S14 (H2B-S14(P)), and the two proteins colocalize at the midbody. HIPK2 depletion by targeted gene disruption or RNA interference results in loss of H2B-S14(P) at the midbody, prevention of cell cleavage, and tetra- and polyploidization. In HIPK2 null cells, restoration of wild-type HIPK2 activity or expression of a phosphomimetic H2B-S14D derivative abolishes cytokinesis defects and rescues cell proliferation, showing that H2B-S14(P) is required for a faithful cytokinesis. Overall, our data uncover mechanisms of a critical HIPK2 function in cytokinesis and in the prevention of tetraploidization.

  • [Show abstract] [Hide abstract] ABSTRACT: By means of ELISA, confocal microscopy, FACS, 2-DE, ImageJ software, MALDI-ToF-MS, and PMF, in this study we report the differentially phosphoproteins expressed in untreated as well as in AZT-treated K562 cells. As evidenced by ELISA, and partly confirmed by confocal microscopy and flow cytometry analysis, an overall increase in Ophosphorylation was found in the AZT-treated samples. Additional analyses allowed to identify 17 spots representing 10 phosphoproteins differentially expressed, proteins which are involved in many significant biological functions such as mRNA processing, assembly and/or transport of ribosome, protein folding, energetic metabolism, cytoskeleton motility, growth control, hypoxia tolerance, allergic and stress responses. Five out of 10 phosphoproteins were up-regulated in K562 cells previously exposed to 20 μM AZT for 3 h (i.e. calreticulin, stathmin, triosephosphate isomerase, stressinduced- phosphoprotein-1, peptidyl-prolyl cis-trans isomerase A). On the contrary, the other five phosphoproteins were down-regulated (i.e. nucleophosmin, lactoylglutathione lyase, 3-hydroxyacyl-CoA dehydrogenase type-2, heterogeneous nuclear ribonucleoproteins A2-B1, alpha-enolase). The proteins identified in the present study represent the first clear report of differential phosphoproteins expression upon AZT treatment of human chronic myeloid leukemia (K562) cells. Therefore, this type of proteomic analysis could be envisaged as a further tool useful for monitoring response(s) to the drug, like the toxic side effects observed in HIV-infected patients under AZT therapy.

    [Show abstract] [Hide abstract] ABSTRACT: Genital infection by high risk Human Papillomavirus (HR-HPV), although recognized as the main etio-pathogenetic factor of cervical cancer, is not per se sufficient to induce tumour development. Oxidative stress (OS) represents an interesting and under-explored candidate as a promoting factor in HPV-initiated carcinogenesis. To gain insight into the role of OS in cervical cancer, HPV-16 positive tissues were collected from patients with invasive squamous cervical carcinoma, from patients with High Grade dysplastic HPV lesions and from patients with no clinical evidence of HPV lesions. After virological characterization, modulation of proteins involved in the redox status regulation was investigated. ERp57 and GST were sharply elevated in dysplastic and neoplastic tissues. TrxR2 peaked in dysplastic samples while iNOS was progressively reduced in dysplastic and neoplastic samples. By redox proteomic approach, five proteins were found to have increased levels of carbonyls in dysplastic samples respect to controls namely: cytokeratin 6, actin, cornulin, retinal dehydrogenase and GAPDH. In carcinoma samples the peptidyl-prolyl cis-trans isomerase A, ERp57, serpin B3, Annexin 2 and GAPDH were found less oxidized than in dysplastic tissues. HPV16 neoplastic progression seems associated with increased oxidant environment. In dysplastic tissues the oxidative modification of DNA and proteins involved in cell morphogenesis and terminal differentiation may provide the conditions for the neoplastic progression. Conversely cancer tissues seem to attain an improved control on oxidative damage as shown by the selective reduction of carbonyl adducts on key detoxifying/pro-survival proteins.

    [Show abstract] [Hide abstract] ABSTRACT: Importin-β is the main vector for interphase nuclear protein import and plays roles after nuclear envelope breakdown. Here we show that importin-β regulates multiple aspects of mitosis via distinct domains that interact with different classes of proteins in human cells. The C-terminal region (which binds importin-α) inhibits mitotic spindle pole formation. The central region (harboring nucleoporin-binding sites) regulates microtubule dynamic functions and interaction with kinetochores. Importin-β interacts through this region with NUP358/RANBP2, which in turn binds SUMO-conjugated RANGAP1 in nuclear pores. We show that this interaction continues after nuclear pore disassembly. Overexpression of importin-β, or of the nucleoporin-binding region, inhibited RANGAP1 recruitment to mitotic kinetochores, an event that is known to require microtubule attachment and the exportin CRM1. Co-expressing either importin-β-interacting RANBP2 fragments, or CRM1, restored RANGAP1 to kinetochores and rescued importin-β-dependent mitotic dynamic defects. These results reveal previously unrecognized importin-β functions at kinetochores exerted via RANBP2 and opposed by CRM1.

    [Show abstract] [Hide abstract] ABSTRACT: Highly stable natural scaffolds which tolerate multiple amino acid substitutions represent the ideal starting point for the application of rational redesign strategies to develop new catalysts of potential biomedical and biotechnological interest. The knottins family of disulphide-constrained peptides display the desired characteristics, being highly stable and characterized by hypervariability of the inter-cysteine loops. The potential of knottins as scaffolds for the design of novel copper-based biocatalysts has been tested by engineering a metal binding site on two different variants of an ω-conotoxin, a neurotoxic peptide belonging to the knottins family. The binding site has been designed by computational modelling and the redesigned peptides have been synthesized and characterized by optical, fluorescence, electron spin resonance and nuclear magnetic resonance spectroscopy. The novel peptides, named Cupricyclin-1 and -2, bind one Cu(2+) ion per molecule with nanomolar affinity. Cupricyclins display redox activity and catalyze the dismutation of superoxide anions with an activity comparable to that of non-peptidic superoxide dismutase mimics. We thus propose knottins as a novel scaffold for the design of catalytically-active mini metalloproteins.
