Abstract:
S100 proteins are calcium-activated signaling proteins that interact with target proteins to modulate biological processes. Our present studies compare the level of expression, and cellular localization of S100A7, S100A8, S100A9, S100A10, and S100A11 in normal and psoriatic epidermis. S100A7 and S100A11 are present in the basal and spinous layers in normal epidermis. These proteins appear in the nucleus and cytoplasm in basal cells but are associated with the plasma membrane in spinous cells. S100A10 is present in basal and spinous cells, in the cytoplasm, and is associated with the plasma membrane. S100A8 and S100A9 are absent or are expressed at minimal levels in normal epidermis. In involved psoriatic tissue, S100A10 and S100A11 levels remain unchanged, whereas, S100A7, S100A8, and S100A9 are markedly overexpressed. The pattern of expression and subcellular localization of S100A7 is similar in normal and psoriatic tissue. S100A8 and S100A9 are strongly expressed in the basal and spinous layers in psoriasis-involved tissue. In addition, we demonstrate that S100A7, S100A10, and S100A11 are incorporated into detergent and reducing agent-resistant multimers, suggesting that they are in vivo trans-glutaminase substrates. S100A8 and S100A9 did not form these larger complexes. These results indicate that S100 proteins localize to the plasma membrane in differentiated keratinocytes, suggesting a role in regulating calcium-dependent, membrane-associated events. These studies also indicate, as reported previously, that S100A7, S100A8, and S100A9 expression is markedly altered in psoriasis, suggesting a role for these proteins in disease pathogenesis.

Abstract:
ABSTRACT The molecular immune response of the pulpal tissue during chronic carious infection is poorly characterized. Our objective was to examine the expression of potential molecular mediators of pulpal inflammation, correlate their levels with disease severity, and determine the cellular localization of key molecules. Results indicated that there was significantly increased transcriptional activity in carious compared to healthy pulp, and the increase correlated positively with disease severity. Semiquantitative reverse transcriptase PCR analysis in 10 carious and 10 healthy pulpal tissue samples of the S100 family members S100A8, S100A9, S100A10, S100A12, and S100A13; the cytokines tumor necrosis factor alpha (TNF-α), interleukin-1β (IL-1β), IL-8, IL-6, and epithelial cell-derived neutrophil attractant 78 (ENA-78); and the structural protein collagen-1α indicated that all genes tested, with the exception of S100A10, were more abundantly expressed in carious teeth. In addition, we found that the closer the carious lesion front was to the pulpal chamber the higher the expression was for all genes except S100A10. Multiple-regression analysis identified a significant positive correlation between the expression levels of S100A8 and IL-1β, ENA-78, and IL-6 and between collagen-1α and S100A8, TNF-α, IL-1β, IL-8, IL-6, and ENA-78. Immunohistochemical studies in carious pulpal tissue indicated that S100A8 and the S100A8/S100A9 complex were predominantly expressed by infiltrating neutrophils. Gene expression analyses in immune system cells supported these findings and indicated that bacterial activation of neutrophils caused upregulation of S100A8, S100A9, and S100A13. This study highlights the complex nature of the molecular immune response that occurs during carious infection.

The expression of the inflammatory S100 calgranulin proteins (S100A8, S100A9 and S100A12) in normal andHelicobacter pylori-infected gastric mucosa of children were examined. S100A8, S100A9 and S100A12, which were virtually absent in normal gastric mucosa, were highly expressed inH pylori-infected mucosa. This expression correlated with the severity of gastritis (r=0.9422, P<0.05). S100 calgranulins may be involved in bacterial-induced gastritis and may limit bacterial growth.

Abstract:
S100A8/A9 (calprotectin) and S100A12 proinflammatory mediators are found at inflammatory sites and in the serum of patients with inflammatory or autoimmune diseases. These cytoplasmic proteins are secreted by neutrophils at sites of inflammation via alternative secretion pathways of which little is known. This study examined the nature of the stimuli leading to S100A8/A9 and S100A12 secretion as well as the mechanism involved in this alternative secretion pathway. Chemotactic agents, cytokines, and particulate molecules were used to stimulate human neutrophils. MSU crystals, PMA, and H2O2induced the release of S100A8, S100A9, and S100A12 homodimers, as well as S100A8/A9 heterodimer. High concentrations of S100A8/A9 and S100A12 were secreted in response to nanoparticles like MSU, silica, TiO2, fullerene, and single-wall carbon nanotubes as well as in response to microbe-derived molecules, such as zymosan or HKCA. However, neutrophils exposed to the chemotactic factors fMLP failed to secrete S100A8/A9 or S100A12. Secretion of S100A8/A9 was dependent on the production of reactive oxygen species and required K+exchanges through the ATP-sensitive K+channel. Altogether, these findings suggest that S100A12 and S100A8/A9 are secreted independently either via distinct mechanisms of secretion or following the activation of different signal transduction pathways.

Abstract:
To investigate the roles of calcium-binding proteins in degranulation, we used three anti-allergic drugs, amlexanox, cromolyn and tranilast, which inhibit IgE-mediated degranulation of mast cells, as molecular probes in affinity chromatography. All of these drugs, which have different structures but similar function, scarcely bound to calmodulin in bovine lung extract, but bound to the same kinds of calcium-binding proteins, such as the 10-kDa proteins isolated in this study, calcyphosine and annexins I–V. The 10-kDa proteins obtained on three drug-coupled resins and on phenyl-Sepharose were analysed by reversed-phase HPLC. It was found that two characteristic 10-kDa proteins, one polar and one less polar, were bound with all three drugs, although S100A2 (S100L), of the S100 family, was bound with phenyl-Sepharose. The cDNA and deduced amino acid sequence proved our major polar protein to be identical with the calcium-binding protein in bovine amniotic fluid (CAAF1, S100A12). The cDNA and deduced amino acid sequence of the less-polar protein shared 95% homology with human and mouse S100A13. In addition, it was demonstrated that the native S100A12 and recombinant S100A12 and S100A13 bind to immobilized amlexanox. On the basis of these findings, we speculate that the three anti-allergic drugs might inhibit degranulation by binding with S100A12 and S100A13.

Abstract:
SUMMARYInfection by larvalEchinococcus granulosusis usually characterized by tight inflammatory control. However, various degrees of chronic granulomatous inflammation are also observed, reaching a high point in infection of cattle by the most prevalent parasite strain worldwide, which is not well adapted to this host species. In this context, epithelioid and multinucleated giant macrophages surround the parasite, and the secreted products of these cells often associate with the larval wall. The phagocyte-specific S100 proteins, S100A8, S100A9 and S100A12, are important non-conventionally secreted amplifiers of inflammatory responses. We have analysed by proteomics and immunohistochemistry the presence of these proteins at theE. granulosuslarva-host interface. We found that, in the context of inflammatory control as observed in human infections, the S100 proteins are not abundant, but S100A9 and S100A8 can be expressed by eosinophils distal to the parasite. In the granulomatous inflammation context as observed in cattle infections, we found that S100A12 is one of the most abundant host-derived, parasite-associated proteins, while S100A9 and S100A8 are not present at similarly high levels. As expected, S100A12 derives mostly from the epithelioid and multinucleated giant cells. S100A12, as well as cathepsin K and matrix metalloproteinase-9, also expressed byE. granulosus-elicited epithelioid cells, are connected to the Th17 arm of immunity, which may therefore be involved in this granulomatous response.

Abstract:
Background. S100 family genes exclusively encode at least 20 calcium-binding proteins, which possess a wide spectrum of intracellular and extracellular functions in vertebrates. Multiple lines of evidences suggest that dysregulated S100 proteins are associated with human malignancies including colorectal cancer (CRC). However, the diverse expression patterns and prognostic roles of distinct S100 genes in CRC have not been fully elucidated. Methods. In the current study, we analyzed the mRNA expression levels of S100 family genes and proteins and their associations with the survival of CRC patients using the Oncomine analysis and GEPIA databases. Expressions and mutations of S100 family genes were analyzed using the cBioPortal, and protein-protein interaction (PPI) networks of S100 proteins and their mutation-related coexpressed genes were analyzed using STRING and Cytoscape. Results. We observed that the mRNA expression levels of S100A2, S100A3, S100A9, S100A11, and S100P were higher and the level of S100B was lower in CRC tissues than those in normal colon mucosa. A high S100A10 levels was associated with advanced-stage CRC. Results from GEPIA database showed that highly expressed S100A1 was correlated with worse overall survival (OS) and disease-free survival (DFS) and that overexpressions of S100A2 and S100A11 were associated with poor DFS of CRC, indicating that S100A1, S100A2, and S100A11 are potential prognostic markers. Unexpectedly, most of S100 family genes showed no significant prognostic values in CRC. Conclusions. Our findings, though still need to be ascertained, offer novel insights into the prognostic implications of the S100 family in CRC and will inspire more clinical trials to explore potential S100-targeted inhibitors for the treatment of CRC.

Abstract:
Pattern recognition receptors (e.g., S100A12 or S100A8/A9) hold promise as inflammatory biomarkers. We prospectively determined and compared serum S100A12 and S100A8/A9 concentrations in dogs with sepsis ( n = 11) or systemic inflammatory response syndrome (SIRS; n = 8) over a 3-d period with each other, healthy controls ( n = 50), and other clinical and clinicopathologic variables. Serum S100A12 and S100A8/A9 concentrations were significantly higher in dogs with sepsis or SIRS (all p < 0.05) at the time of hospital admission (day 1) compared to healthy controls, with no differences between patient groups. However, septic dogs had significantly lower serum S100A12 concentrations on day 2 and day 3 (both p < 0.05) compared to dogs with SIRS. Likewise, dogs with sepsis had significantly lower S100A8/A9 concentrations on day 2 ( p < 0.05). Neither serum S100A12 nor S100A8/A9 concentrations were associated with survival to discharge. Our results suggest a differential expression of the S100/calgranulins between dogs with sepsis and those with SIRS. Serum S100A12 or S100A8/A9 concentration at the time of hospital admission did not differentiate dogs with sepsis from those with SIRS, but the trend of S100/calgranulin concentrations during the following 24–48 h may be a useful surrogate marker for differentiating sepsis from SIRS.

Abstract:
S100 proteins are involved in the pathogenesis of sporadic colorectal carcinoma through different mechanisms. The aim of our study was to assess tissue mRNA encoding S100 proteins in patients with non-advanced and advanced colorectal adenoma. Mucosal biopsies were taken from the caecum, transverse colon and rectum during diagnostic and/or therapeutic colonoscopy. Another biopsy was obtained from adenomatous tissue in the advanced adenoma group. The tissue mRNA for each S100 protein (S100A4, S100A6, S100A8, S100A9, S100A11 and S100P) was investigated. Eighteen biopsies were obtained from the healthy mucosa in controls and the non-advanced adenoma group (six individuals in each group) and thirty biopsies in the advanced adenoma group (ten patients). Nine biopsies were obtained from advanced adenoma tissue (9/10 patients). Significant differences in mRNA investigated in the healthy mucosa were identified between (1) controls and the advanced adenoma group for S100A6 (p = 0.012), (2) controls and the non-advanced adenoma group for S100A8 (p = 0.033) and (3) controls and the advanced adenoma group for S100A11 (p = 0.005). In the advanced adenoma group, differences between the healthy mucosa and adenomatous tissue were found in S100A6 (p = 0.002), S100A8 (p = 0.002), S100A9 (p = 0.021) and S100A11 (p = 0.029). Abnormal mRNA expression for different S100 proteins was identified in the pathological adenomatous tissue as well as in the morphologically normal large intestinal mucosa.

Abstract:
Increasing evidence indicates calcium-binding S100 protein involvement in inflammation and tumor progression. In this prospective study, we evaluated the mRNA levels of two members of this family, S100A9 and S100A12, in peripheral blood mononuclear cells (PBMCs) in a cohort of 121 prostate cancer patients using RT-PCR. Furthermore, monocyte count was determined by flow cytometry. By stratifying patients into different risk groups, according to TNM stage, Gleason score and PSA concentration at diagnosis, expression of S100A9 and S100A12 was found to be significantly higher in patients with metastases compared to patients without clinically detectable metastases. In line with this, we observed that the protein levels of S100A9 and S100A12 in plasma were higher in patients with advanced disease. Importantly, in patients with metastases at diagnosis, high monocyte count and high levels of S100A9 and S100A12 were significantly associated with short progression free survival (PFS) after androgen deprivation therapy (ADT). High monocyte count and S100A9 levels were also associated with short cancer-specific survival, with monocyte count providing independent prognostic information. These findings indicate that circulating levels of monocytes, as well as S100A9 and S100A12, could be biomarkers for metastatic prostate cancer associated with particularly poor prognosis.

Abstract:
The S100s comprise a group of Ca2+-binding proteins of the EF-hand superfamily with varied functions. Within this family, three inflammatory-related proteins - S100A8, S100A9 and S100A12 - form a subcluster known as the 'calgranulins'. S100A12 levels are elevated in sera from patients with inflammatory diseases, such as rheumatoid arthritis and inflammatory bowel disease. S100A12 is constitutively expressed in neutrophils and induced in monocytes by LPS and TNFα, and in macrophages by IL-6. S100A12 is a potent monocyte and mast cell chemoattractant and its potentiation of mast cell activation by IgE cross-linking indicates an important role in allergic inflammation. Importantly, mast cell-dependent activation of acute inflammatory responses and monocyte recruitment is provoked by S100A12 administration in vivo. S100A12 may also influence adhesion molecule expression on endothelial cells, stimulate IL 1β and TNFinduced in monocytes production in BV 2 microglial cells, and stimulate IL 2 secretion by T lymphocytes via ligation of the receptor for advanced glycation end-products (RAGE). To date, the only extracellular receptor characterised for S100A12 is RAGE, although additional/alternate receptors are indicated. In particular, recent studies indicate that chemotaxis and mast cell activation by S100A12 are likely mediated by other receptors. The studies presented here investigated some extracellular functions of S100A12, factors influencing these functions and suggest mechanisms that may be involved. In addition to Ca2+, S100A12 binds Zn2+. Chapter 3 explores the relevance Zn2+ binding to S100A12 structure and function. Zn2+ induced formation of complexes, principally hexamers, and this was not influenced by Ca2+. S100A12 inhibited the gelatinolytic activities of matrix metalloproteinase (MMP)-2 and 9 by chelating Zn2+ from their active sites. MMPs are important in processes leading to plaque rupture. An antibody that specifically recognised Zn2+-induced complexes was generated and immunohistochemical studies demonstrated S100A12, the hexameric complex, and MMP 2 and 9 co-localisation in human atheroma. These results suggest that hexameric S100A12 may form in vivo and may implicate S100A12 in regulating plaque rupture by inhibiting MMP activity. Interestingly S100A12 synergised with LPS to induce MMP 3 and 13 expression in vitamin D3-differentiated THP 1 macrophages (THP 1 macs). S100A12 regulation of MMP expression and activity indicates that it may be involved in a self-regulatory loop, which depends on relative levels of Zn2+ and on other stimuli (eg LPS) in the inflammatory milieu. Chapter 4 describes the development of tools and methods for assessing interactions of S100A12 with cell surface receptors. To assay surface binding, an alkaline phosphatase fusion protein, a biotinylated hinge peptide and biotinylated recombinant S100A12 were generated; only S100A12 b proved useful. Surface binding of S100A12 was detected on several monocytoid/macrophage and mast cells using flow cytometry and immunocytochemistry. Some cells contained intracytoplasmic granular structures that were S100A12-positive. Unexpectedly, a subpopulation of cells in murine bone marrow-derived mast cell cultures that expressed low levels of c-kit, a marker of mature mast cells, bound high levels of S100A12. These may represent haematopoietic stem cells, which express low levels of c kit, and S100A12-mediated functional changes of these cells is worthy of characterisation. Unlike interactions of S100A8/A9 with endothelial cells, pre-incubation of S100A12 with Zn2+ or heparin had no effect on surface binding to THP 1 macs, indicating that Zn2+-induced structural changes were unlikely to alter receptor interactions. Heparan sulfate moieties are unlikely to mediate surface binding of S100A12 even though S100A12 bound heparin with relatively high affinity. Chapter 5 focussed on mechanisms involved in some S100A12 extracellular functions. Based on experiments studying effects of bovine S100A12 on BV-2 murine microglial cells, S100A12 is proposed to induce pro-inflammatory cytokine in monocytes via RAGE. Human peripheral blood mononuclear cells or human THP 1 macs activated with S100A12 did not increase cytokine induction at the mRNA or protein levels, indicating that the 'S100/RAGE pro-inflammatory axis' theory should be re-evaluated. In an attempt to provide insights into a novel receptor, mechanisms involved in S100A12-provoked THP 1 chemotaxis were investigated. This activity was sensitive to pertussis toxin, but not to an ERK1/2 pathway inhibitor, suggesting involvement of a G protein-coupled receptor. Although some RAGE ligands also bind and activate Toll-like receptors (TLRs) antibodies to TLR2 and TLR4 did not block S100A12 binding to THP 1 macs. Affinity enrichment and separation of proteins by SDS PAGE and peptide mapping by mass spectrometry identified the α and γ subunits of F1 ATP synthase, implicating ATP synthase as a putative receptor. Although primarily mitochondrial, this complex is expressed on the surface of several cell types and was confirmed on THP 1 cells and mast cells by flow cytometry. By modulating surface F1 ATP synthase activity, and thereby extracellular ATP/ADP concentrations, S100A12 may mediate its pro-inflammatory functions through G-protein coupled purinergic receptors. This work has generated new directions for studying mechanisms by which S100A12 influences monocyte/macrophage and mast cell functions that are relevant to important inflammatory diseases, such as atherosclerosis and allergic inflammation.

Bien que les protéines S100A8/A9 et S100A12 exprimées par les neutrophiles ne possèdent pas de peptide signal, elles sont retrouvées dans le sérum de patients souffrant de diverses maladies inflammatoires. Les mécanismes de sécrétion de ces protéines demeurent peu connus ainsi que les agonistes qui favorisent leur sécrétion. Nous avons donc émis l´hypothèse que plusieurs voies de sécrétion alternative ainsi que plusieurs agonistes des neutrophiles pourraient participer à la libération de ces protéines. Dans un premier temps, nous avons étudié les stimuli capables de provoquer la sécrétion de la calprotectine et/ou de la S100A12. Dans une deuxième partie, nous nous sommes intéressés aux signaux et mécanismes alternatifs de sécrétion impliqués dans le relargage de ces protéines. L’ensemble de ces travaux montre la complexité des voies de sécrétion alternatives impliquées dans la sécrétion des protéines S100 et comment ces voies sont influencées par l’activation des neutrophiles par différents agonistes.
Although S100A8/A9 (calprotectin) and S100A12 proteins expressed by neutrophils lack a signal peptide, they are found in the serum of patients with various inflammatory diseases. However, the mechanisms of secretion and the agonists that promote their secretion are still unknown. We hypothesized that several alternative secretory pathways and several agonists of neutrophils may participate in the release of S100A8/A9 and S100A12 protein. Initially, we studied the stimuli inducing the secretion of calprotectin and / or S100A12. In a second part, we were interested in signals and alternative mechanisms of secretion involved in the release of the calprotectin and S100A12. In conclusion, this study shows the complexity of alternative secretion pathways involved in S100 secretion and that these pathways are influenced by the activation of neutrophils by various agonists.

Le sepsis est la 3eme cause de mortalité dans les pays occidentaux, avec un taux de mortalité entre 20 et 50% selon la sévérité. La « prédiction » du devenir clinique du patient est essentielle pour établir le traitement le plus adéquat. Quelques protéines marqueurs de l'inflammation ou d'une infection (CRP, procalcitonine) sont citées pour le suivi des patients en clinique mais manquent de spécificité pour le sepsis. D'autre part, les études « omiques » ont permis de générer des listes de biomarqueurs potentiels du pronostic vital du sepsis. En revanche, aucun n'a encore été validé et/ou confirmé en fonction de la gravité du sepsis et du devenir du patient. Il faut pour cela accéder non seulement à des cohortes de patients parfaitement caractérisées et également disposer de méthodes quantitatives robustes et validées. La spectrométrie de masse apporte une capacité de spécificité et de multiplexage à haut niveau qui permettait de confirmer l'intérêt d'une ou plusieurs de ces protéines dans le cas du pronostic du sepsis. Les dosages immunologiques apportent quant à eux en plus de la sensibilité et de la spécificité, une mise en œuvre en routine clinique simple et rapide. Dans un premier temps, une liste de biomarqueurs identifiés avec des cohortes de patients a été établie d’après la littérature. Puis, des méthodes de quantification de ces biomarqueurs ont été développées. Nous nous sommes intéressés d’une part à quantifier les calgranulines dans le plasma en développant des ELISA et des méthodes de spectrométrie de masse par des approches bottom-up et top-down. D’autre part, deux méthodes de quantification multiplexes ont été développées par spectrométrie de masse avec et sans étape d’immunopurification en fonction des concentrations des protéines présentes dans le plasma afin de vérifier la pertinence de la liste de biomarqueurs potentiels. Toutes ces méthodes ont été appliquées à une cohorte de 49 patients atteints de choc septique
Sepsis is the 3rd leading cause of death in Western countries, with a mortality rate between 20 and 50% depending on the severity. The 'prediction' of the patient's clinical outcome is essential to establish the most appropriate treatment. Some inflammation or infection markers protein (CRP, procalcitonin) are cited for clinical follow-up of patients but lack specificity for sepsis. On the other hand, "omics" studies have generated lists of potential biomarkers of sepsis prognosis. However, none have yet been validated and/or confirmed based on the severity of the sepsis and the patient's fate. This requires access not only to fully characterized patient cohorts but also to robust and validated quantitative methods. Mass spectrometry provides a high level of specificity and high multiplex capacity and that would allow to confirm the interest of one or more of these proteins for sepsis prognosis. Immunological assays provide, in addition to sensitivity and specificity, a simple and rapid routine clinical implementation. First, a list of biomarkers identified with patient cohorts was established from the literature. Then, methods to quantify these candidate biomarkers were developed. On the one hand, we have been interested in quantifying calgranulins in plasma by developing ELISAs and mass spectrometry methods using bottom-up and top-down approaches. On the other hand, two multiplex quantification methods by mass spectrometry with and without immunopurification step according to protein concentrations have been developed to verify the relevance of the list of potential biomarkers. All these methods were applied to a cohort of 49 patients with septic shock

Abstract:
O trabalho ora apresentado foi concebido como tendo dois objetivos. O primeiro, mais geral, foi implementar uma nova metodologia para o estudo de mudanças conformacionais em proteínas, ou seja, de sua dinâmica estrutural. A técnica de marcação de spin sítio dirigida aliada à ressonância paramagnética eletrônica (SDSL-RPE) são os pilares desse novo método que faz, agora, parte do conjunto de técnicas disponíveis no Grupo de Biofísica Molecular Sérgio Mascarenhas do Instituto de Física de São Carlos (USP). O segundo objetivo, mais específico, representou o caminho efetivamente tomado para que se alcançasse o objetivo geral. Para isso, foi proposto o estudo da correlação estrutura e função de dois sistemas biológicos muito interessantes. O primeiro deles envolveu o estudo do movimento das hélices que compõem a estrutura da proteína ligante de cálcio S100A12 humana (HS100A12) induzido pelos íons cálcio e zinco. Sabendo que a proteína S100A12 humana além de ligar íons Ca+2, apresenta afinidade por outros metais divalentes, como os íons Zn+2 e Cu+2, e que a formação de diferentes oligômeros da proteína é governada pela concentração dos íons Ca+2 e Zn+2, realizamos estudos espectroscópicos utilizando a técnica de dicroísmo circular a fim de investigarmos a estabilidade térmica da proteína HS100A12 na presença e ausência dos íons cálcio e zinco. Mudanças conformacionais na estrutura da HS100A12 foram monitoradas através da construção de uma série de mutantes (simples e duplos) em que resíduos nas hélices B, C e D foram trocados por cisteínas, subsequentemente marcadas com a sonda magnética MTSSL e submetidas às análises de SDSL-RPE. Estas consistiram na medida do espectro de RPE dos vários mutantes em temperatura ambiente para estudarmos os efeitos da presença dos íons sobre a dinâmica experimentada pela sonda nas diversas posições. Além disso, efetuamos medidas de distância entre duas sondas seletivamente inseridas na estrutura protéica, procurando assim complementar o entendimento acerca do efeito da presença dos íons sobre a proteína. Por fim, devido ao fato da proteína HS100A12 estar envolvida em alguns eventos de sinalização celular e interação com o receptor para produtos de glicosilação (RAGE), decidimos também, estudar a interação da proteína com modelos de biomembranas, utilizando monocamadas de Langmuir. O outro problema de interesse utilizou a lizosima do fago T4, uma proteína padrão, da qual uma variedade de mutantes é produzida rotineiramente a fim de obtermos mais detalhes a respeito da sua correlação estrutura e função e tornar mais sólido o entendimento da técnica SDSL. Inicialmente, realizamos um estudo com a suposta criação de uma cavidade no \"core\" hidrofóbico da porção C-terminal da enzima, quando mutamos a Leu 133 por Ala e/ou Gly, ou seja, quando trocamos um resíduo grande por um de menor volume, pois se acredita que a proteína sofra um reajuste estrutural com o intuito de preencher o espaço vazio criado por essa substituição. Para isso, propusemos estudar por SDSL o movimento da α-hélice H inserindo o marcador de spin na posição vizinha ao resíduo mutado. Adicionalmente, realizamos um experimento de \"transmutação\" com a enzima T4L, a fim de investigar a natureza das contribuições para os diferentes modos dinâmicos experimentados pelo marcador de spin quando introduzido em sítios topologicamente semelhantes.
The work presented here was conceived with two main objectives. The first one, more general, involved the implementation of a new methodology for the study of conformational changes in proteins, i.e., its structural dynamics. The technique of Site-directed Spin Labeling combined with Electronic Paramagnetic Resonance (SDSL-EPR) are the pillars of this new method, which is now part of the set of techniques available at the Grupo de Biofísica Molecular Sérgio Mascarenhas, Instituto de Física de São Carlos (USP). The second objective, more specific, represented the path actually taken to achieve the overall goal. Therefore, it was proposed to study the structure-function correlation in two interesting biological systems. The first involved the study of the movement of the helices that form the structure of the human calcium binding protein S100A12 (HS100A12) induced by calcium and zinc ions. Knowing that, besides Ca+2, human S100A12 has also affinity for other divalent metals, such as Zn+2 and Cu+2 ions, and that the formation of different protein oligomers is governed by the concentration of Ca+2 and Zn+2, we performed spectroscopic studies using circular dichroism (CD) to investigate the thermal stability of protein HS100A12 in the presence and absence of calcium and zinc. Conformational changes in the structure of HS100A12 were monitored by producing a series of mutants (singles and doubles) in which residues in helices B, C and D were replaced by cysteine and subsequently labeled with a magnetic probe MTSSL and then analyzed via SDSL-EPR. The latter consisted of the EPR spectra measurement of many mutants at room temperature to study the effects of the presence of ions on the dynamics experienced by the probe in different positions. In addition, we performed measurements of the distance between two probes inserted in the protein structure, thereby, seeking to improve the understanding of the effect of the ions presence on the protein. Finally, due to the fact that HS100A12 is involved in some events of cell signaling and interaction with the Receptor for Advanced Glycation End Products (RAGE), we also decided to study the interaction of protein with models of biomembranes using Langmuir monolayers. In the other problem of interest, we used a variety of mutants of the enzyme T4 lysozyme, a protein standard, in order to obtain more details about its structure-function correlation and make more solid the understanding of SDSL technique. Initially, we conducted a study about the alleged creation of a cavity in the hydrophobic C-terminal portion of the enzyme, when we replaced the Leu 133 by Ala and/or Gly, or when we changed a large residue for a smaller one, because it is believed that the protein undergoes a structural adjustment in order to fill the gap created by this substitution. For this, we studied by SDSL the α-helix H motion, inserting the spin label in a neighbor position of the mutated residue. Additionally, we performed an experiment of \"transmutation\" with the enzyme T4L in order to investigate the nature of contributions for different dynamic modes experienced by the spin label when it is introduced in topologically similar sites.

Abstract:
Calgranulina C (S100A12) é membro da família das proteínas S100 \"EF-hands\" que complexam cálcio. A S100A12 humana é expressa predominantemente por granulócitos e é superexpressa em compartimentos inflamatórios. Níveis séricos elevados de S100A12 são encontrados em pacientes acometidos por distúrbios inflamatórios, neurodegenerativos, metabólicos e neoplasias. A S100A12 intracelular existe como um homodímero anti-paralelo. Cada monômero é composto por um \"EF-hand\" clássico, C-terminal (HI - LI - HII), e um \"EF-hand\" N-terminal, o pseudo \"EF-hand\" (HIII - LIII - HIV). Os \"motifs\" são conectados pela região do \"hinge\" (LII). A Calgranulina C também liga íons zinco e cobre em uma região formada pelas duas subunidades do dímero. Mudanças nas concentrações citosólicas de íons regulam uma grande variedade de processos celulares, e as proteínas que complexam íons são moléculas importantes na transdução do sinal, diferenciação e controle do ciclo celular. O mecanismo pelo qual a Calgranulina C modula o curso do processo inflamatório está relacionado à interação com o receptor para produtos finais de glicosilação (RAGE). Para obter detalhes sobre os mecanismos envolvidos nas etapas de sinalização celular das quais a S100A12 participa, nosso objetivo foi qualificar e quantificar a atividade conformacional dos domínios da S100A12 induzida por variações de parâmetros termodinâmicos intensivos, como mudanças nas concentrações de íons. Além disso, nós investigamos os detalhes da interação entre S100A12 e RAGE para elucidar a região do receptor com a qual a S100A12 interage e quais são os resíduos envolvidos nesta interação. Para os estudos da influência da presença de íons na dinâmica conformacional da S100A12, simulações de dinâmica molecular foram realizadas usando o pacote de simulação GROMACS com o campo de força OPLS-AA, no \"ensemble\" NVT. As estruturas iniciais usadas foram as estruturas cristalográficas da S100A12 (PDB ID: 2WCE e 1E8A). Estas foram submetidas a diferentes concentrações de cloreto de sódio, cálcio e zinco em sistemas separados e solvatados com o modelo de água \"SPC\". Nossos resultados sugerem que em baixas concentrações de Ca2+, o LI permanece ocupado pelo Na+. No período entre ondas de Ca2+, este íon tem acesso à proteína exclusivamente pelo LIII (no EF-2). A medida em que há presença de Zn2+, esse contribui para a saída do Na+ do LI, evento que envolve a participação do resíduo Asp25, permitindo que o LI se abra e descomplexe o Na+. Além disso, devido a alta deformabilidade estrutural, a HIII é muito influenciada pelos íons Na+ e Ca2+, sendo que em determinadas concentrações, ambos levam a perda parcial desta hélice e da HIIa (\"Hinge-Region\") e ao aumento da flexibilidade desta região, embora apenas o Ca2+ seja capaz de se complexar, via HIII, a região próxima ao LIII. Com relação aos estudos com o RAGE, foram realizados estudos de \"docking\" molecular e simulações de SMD (\"Steered Molecular Dynamic\"). A análise dos nossos resultados, sugere que a interação da S100A12 com o RAGE ocorre tanto no domínio V, quanto no domínio C1 do RAGE e depende da região de conexão entre estes domínios. Também, observamos que estados oligoméricos maiores, por exemplo, hexâmeros de S100A12 (PDB ID: 1GQM), têm possibilidades maiores de interação com RAGE e que nestes casos, as regiões relevante da interação envolvem, de acordo com nossos resultados, porções N e C-terminal da HI e C-terminal da HIV da S100A12.
Calgranulin C (S100A12) is a member of the S100 family of EF-hand calcium-binding proteins. Human S100A12 is predominantly expressed by granulocytes and is markedly overexpressed in inflammatory compartments. Elevated serum levels of S100A12 are found in patients suffering from various inflammatory, neurodegenerative, metabolic, and neoplasic disorders. Intracellular S100A12 exists as an anti-parallel homodimer. Each monomer is composed of a C-terminal, classic EF-hand (HI - LI - HII), an N-terminal, pseudo EF-hand (HIII - LIII - HIV). The motifs are linked by the hinge-region. Calgranulin C also binds zinc and copper ions in a site formed by both subunits of dimer. Changes in cytosolic ions concentrations regulate a wide variety of cellular process, and ions-binding proteins are the key molecules in signal transduction, differentiation, and cell cycle control. The mechanism by which calgranulin C modulates the course of inflammatory process is related to its interaction with the receptor for advanced glycated products (RAGE). In order to obtain details about the mechanism involved in cell signaling steps in which S100A12 participates, our goal was to qualify and quantify the activity conformational of S100A12 domains, induced by variations of intensive thermodynamic parameters, as changes in the concentration of ions. Furthermore we investigated the details of the interaction between S100A12 and RAGE in order to elucidate the region of the receptor which interacts with S100A12 and what are the residues involved in this interaction. In order to access the influence of the presence of ions over the conformational dynamics of S100A12, molecular dynamics simulations were performed using the GROMACS suite with the OPLS-AA force field and NVT ensemble. The initial structures used were experimentally determined by X-ray crystallography (PDB ID: 2WCE and 1E8A). They were separately submitted to different concentrations of sodium, calcium and zinc chloride and solvated with the SPC water model. Our results suggest that at low concentrations of Ca²?, LI remains occupied by Na?. During calcium-waves, it can reach the protein exclusively through LIII (in EF-2). As the Zn²? concentration rises, it contributes to the Na? unbinding from LI, an event that involves the residue ASP-25, which allows LI to open and the Na? to unbind. Furthermore, because of its high structural deformability, HIII is strongly influenced by both Na? and Ca²? ions which, in certain concentrations, leads to partial loss of this helix and of HIIa (Hinge-Region) and increases in the flexibility of this region, although only Ca²? is able to bind, through HIII, to the region near LIII. Regarding the RAGE studies, molecular docking essays and SMD (Steered Molecular Dynamics) simulations were performed. Our data analysis suggests that the interaction between S100A12 and RAGE takes place through both V and C1 RAGE domains and depends upon the interdomain region. Additionally, we observed that higher oligomeric states, e.g. S100A12 hexamers (PDB ID: 1GQM), have more interaction possibilites with RAGE and that, according to our results, in this case the interacting region of S100A12 comprises the N- and C-terminal portions of HI and Cterminal of HIV.

Abstract:
S100A12 porcina é um membro da família das proteínas S100, um grupo de pequenas proteínas ligantes de cálcio caracterizado pela presença de dois motivos “EF-hand”. Estas proteínas estão envolvidas em diversos eventos celulares, como a regulação da fosforilação protéica, atividade enzimática, tamponamento de Ca+2, processos inflamatórios e a polimerização de filamentos intermediários. Adicionalmente, algumas dessas proteínas podem ligar Zn+2, o qual pode afetar a ligação do íon Ca+2, particularmente para as proteínas S100. Neste trabalho, a seqüência gênica que codifica a proteína S100A12 porcina foi obtida por meio da construção de um gene sintético usando códons preferenciais para E.coli, permitindo a produção recombinante de grandes quantidades da proteína. Um estudo termodinâmico da estabilidade estrutural foi realizado, assim como a interação da proteína recombinante com íons divalentes usando técnicas de dicroísmo circular (CD) e fluorescência extrínseca. A desnaturação e renaturação induzidas por uréia ou temperatura indicam que se trata de um processo reversível e que a ligação dos íons Zn+2 e ou Ca+2 à rS100A12 aumenta sua estabilidade. A interação da sonda ANS com a proteína na presença de seus ligantes expõe superfícies hidrofóbicas podendo assim facilitar sua interação com macromoléculas alvo. Analisados em conjunto, os resultados obtidos indicam que S100A12 porcina é capaz de assumir diferentes conformações as quais podem estar correlacionadas com sua função fisiológica.
Porcine S100A12 is a member of S100 family, a small acidic calcium-binding proteins group characterized by the presence of two EF-hand motifs. These proteins are involved in many cellular events as the regulation of protein phosphorylation, enzymatic activity, Ca+2 homeostasis, inflammatory processes and intermediate filament polymerization. In addition, some of these proteins can bind Zn+2, which can affect the binding of Ca+2 particularly to S100 proteins. In this study, the gene sequence encoding S100A12 was obtained by the synthetic gene approach using E. coli codon bias allowing the recombinant production of large amounts of the protein. We report here a thermodynamic study on the structural stability of this recombinant protein and its interaction with divalent ions using circular dichroism and extrinsic fluorescence. The folding/unfolding induced by urea or temperature indicated a reversible process and the binding of Zn+2 or Zn+2 and Ca+2 to S100A12 increasing its stability. The interaction of the ANS probe with the protein in the ligant presence can lead to exposition of hydrofobic regions allowing its interaction with target macromolecules. Taken together, the results indicated that porcine S100A12 may assume different conformations that could be correlated to its physiological function.
