Les protéines accomplissent leur fonction dans la cellule grâce à leur faculté de changer de forme. Chaque classe de protéines peut se caractériser par une structure spécia- lisée partagée par ses membres avec un certain degré de variabilité. Tel est le cas des protéines à motifs mains-EF, qui se transforment en liant et déliant l ’ion calcium. Ce motif permet à la Troponin C de s’ouvrir et se refermer afin de moduler le mécanisme de contraction des fibres musculaires. Un mécanisme similaire permet à la Calmoduline de gérer l’activité de divers canaux cellulaires. Les techniques de simulations numériques peuvent aider à comprendre les trajectoires de ces transformations. Le projet principal de cette thèse consistait à développer une méthode informatique multi-échelle permettant de simuler des mouvements complexes à l’intérieur d ’une protéine. La représentation multi-échelle développée peut changer et s’adapter en cours de simulation. La méthode, ART holographique, explore l’espace en générant des basculements d’ensembles atomiques, selon des champs de force atomistiques non biaisés indiquant à tout moment comment les ensembles doivent pivoter. La méthode réduit le calcul des fluctuations locales mais conserve une représentation spatiale complète. La représentation multi-échelle est combinée à une technique de recherche de passages de transition énergétiquement favorables, ART nouveau, qui conduit la trajectoire moléculaire d ’étape en étape. Appliquée à plusieurs protéines, dont la Calmodulin et la Troponin C, ART holographique génère des trajectoires de transformation entre des conformations distantes de celles-ci, déjà connues grâce aux techniques de RMN ou de cristallographie. L’usage d ’une représentation spatiale complète tout au long de la simulation favorise le discernement de certains détails des mécanismes. Le rôle, l’ordre d ’intervention, ainsi que la coopérativité de certains résidus et structures impliqués dans le mécanisme des paires main-EF ont été explorés plus en détail et un état intermédiaire est proposé. / Proteins accomplish their function inside cells by means of conformational changes. Each protein class may be characterized by a specialized structure shared by its members with some variability. EF-hands proteins present a special motif which transforms itself while binding or unbinding the calcium ion. This structure allows Troponin C domains to open and close as it modulates the muscular fibers contraction. A similar mechanism allow Calmodulin to manage the activity of a diversity of protein channels. Computational techniques may help discover how these transformations occur. The main project of this thesis was the development of a multi-scale computational method for the simulation of complex motions inside a protein. The multi-scale approach is designed to adapt and change all along the simulation. The method, holographic ART, explore conformational space by generating swiveling and rotation of atomic ensembles, leaded by non biased atomistic forcefields. This determines at each step the overall motion, keeping a complete spatial representation, but with minimal local fluctuations computation. The multi-scale representation is combined with a unbiased open ended algorithm for identifying transitions states, ART nouveau, which guides the molecular trajectory from state to state. Applied to several proteins, the method was able to generate transforma- tion trajectories between distant conformations known from NMR and crystallography techniques. The use of a complete spatial representation throughout the simulation allows the method to capture atomistic details of each event. The purpose, the intervention order, as well as cooperativity between some residues and sub-structures involved in the EF-hand pair mechanism have been explored more in detail and an intermediate state is proposed. / Les films de simulations qui accompagnent le document ont été réalisés avec Pymol.

Background: Heart damage from cancer therapy is a significant problem for survivors. Some of the most effective treatments, such as anthracyclines, cause heart toxicity that can lead to significant morbidity and mortality. Cardiotoxicity also contributes to the loss of promising cancer drugs in early development and is notoriously difficult to predict. This translational project employs parallel pre-clinical and clinical studies to explore circulating biomarkers and cardiac magnetic resonance imaging (CMR) during development of anthracycline associated cardiotoxicity with the aim of finding biomarkers to aid clinical decision making and enable forward/back translation. Methods: Pre-clinical work: A rat model of chronic anthracycline-induced cardiomyopathy was developed involving 8 weekly intravenous boluses of doxorubicin followed by a 4 week ‘washout’ period. A time course assessment of cardiac function using multiple MRI parameters was performed alongside a panel of circulating biomarkers measured prior to dosing. Clinical work: In parallel following ethical approval, 30 cancer patients receiving standard anthracycline chemotherapy were recruited. Serial CMR scans were performed using standard and new exploratory techniques before, during and after treatment and blood was taken to evaluate a similar panel of cardiotoxicity biomarkers using multiplex ELISA at corresponding time points. Results: Pre-clinical results: Systolic and diastolic function declined progressively, culminating in left ventricular dysfunction (LVEF < 50%) by 12 weeks. Myocardial electron microscopy revealed myofibrillar and mitochondrial damage after one dose and gross histopathological damage after 5 doses. Myocardial contrast enhancement and troponin I increased significantly after eight doses and preceded LV dysfunction. Extensive fibrosis was seen 1 month after drug cessation. Clinical results: LVEF declined progressively in all patients and 7 patients (23%) had persistent LV dysfunction 12 months after therapy. Troponin I elevations were seen towards the end of therapy and peak troponin I corresponded with LVEF decline. None of the other circulating biomarkers correlated strongly with outcome. Lower baseline extracellular volume (ECV) was associated with greater LVEF decline but little change in ECV was seen over time. Baseline dyssynchrony was associated with worse outcome and deteriorated with time alongside LVEF decline. Conclusions: Results suggest that troponin I and cardiac MRI are sensitive translational tools in drug induced cardiotoxicity. However, troponin I is a relatively late marker, peaking after substantial myocardial damage, too late to halt or change reatment. The imaging suggests that fibrosis and inflammation cannot be detected within a year of chemotherapy but baseline ECV and strain analysis may have a role in risk stratification.

Esse estudo descreve casos de “morte súbita” em bovinos associados com a ingestão de Amorimia (Mascagnia) exotropica em seis propriedades rurais localizadas na região metropolitana de Porto Alegre e da serra gaúcha. Os bovinos intoxicados foram encontrados mortos sem história de sinais clínicos prévios, ou apresentaram tremores musculares, quedas bruscas, movimentos de pedalagem, opistótono, respiração ofegante e decúbito lateral, quando induzidos ao movimento poucos minutos antes da morte. Registrou-se maior número de casos entre os meses de maio e agosto. Nove bovinos foram necropsiados e os principais achados macroscópicos observados foram mucosa oral levemente cianótica (3/9), hidropericárdio leve a moderado (3/9), petéquias e equimoses no epicárdio (5/9), coágulo no interior do ventrículo esquerdo (4/9), edema pulmonar (5/9) e mucosas vermelhas no abomaso e no intestino delgado (6/9). Histologicamente havia necrose de coagulação no miocárdio (9/9) caracterizada por retração celular, aumento da eosinofilia do citoplasma com perda das estriações, núcleos em picnose e ocasionais núcleos em cariorrexia e cariólise. No coração, edema intersticial (3/9) e infiltrado inflamatório intersticial, predominantemente, mononuclear (7/9) também foram observados. Nos rins de três bovinos havia degeneração hidrópicovacuolar multifocal das células epiteliais dos túbulos contorcidos distais associada com núcleos picnóticos deslocados para periferia da célula. As lesões cardíacas desses bovinos foram demonstradas através da imuno-histoquímica para troponina cardíaca C (cTnC). Nos corações dos bovinos intoxicados ocorreu diminuição acentuada de cTnC no citoplasma de grupos dos cardiomiócitos com características microscópicas de degeneração e necrose e, em algumas áreas havia perda total de imunomarcação. Raras fibras musculares cardíacas sem alteração histológica apresentaram perda de imunomarcação. Nos demais cardiomiócitos dos bovinos intoxicados sem lesões histológicas observou-se intensa marcação citoplasmática. / This study describes cases of sudden death in cattle that were associated with the consumption of Amorimia (Mascagnia) exotropica and occurred in six ranches located in the mountainous region of Rio Grande do Sul and the metropolitan region of Porto Alegre, Brazil. Affected cattle were found dead with no history of previous clinical signs, or showed muscular tremors, falls, paddling, opistotonus, panting, and lateral recumbence after being induced to move, few minutes before death. Most cases were recorded between May and August. Nine cattle were necropsied and main gross findings were oral mucosa slightly cyanotic (3/9), mild to intermediate hydropericardium (3/9), epicardial petechiae and ecchymoses (5/9), clot within the left ventricle (4/9), lung edema (5/9), apart of abomasal and small intestinal reddened mucosa (6/9). Histologically, there was myocardial coagulation necrosis (9/9), which was characterized by cellular retraction, enhanced cytoplasmic eosinophilia, lack of cytoplasmic striations and occasional nuclear karyorrhexis and karyolysis. There also were interstitial edema (3/9) and interstitial inflammatory infiltrate (mainly mononuclear) (7/9) in the heart. Apart of multifocal vacuolar-hydropic degeneration in the epithelial cells of the distal convoluted tubules associated with pyknotic and eccentric nuclei in the kidneys of three cattle. The cardiac lesions of these cattle were demonstrated by immunohistochemistry for cardiac troponin C (cTnC). In the hearts of cattle intoxicated was severe reduction of the cTnC in the cytoplasm of cardiomyocytes groups with microscopic features of degeneration and necrosis, and in some areas with complete loss of immunoreactivity. Rare cardiac muscle fibers showed no histological abnormality loss of immune-marking. In the remaining cardiomyocytes in cattle poisoned histological lesions were absent, but an intense cytoplasmic staining in these cells was observed.

Methods: This is a study of a prospective cut, which evaluates 49 consecutive patients who underwent coronary angioplasty with stent implantation. A cTnI serum dosage was done both before and after the procedure. Patients with a cut off >1.0 ng/mL before implantation were excluded. All the others received follow up for one year, to record the presence of ACE (death, acute myocardial infarction, another angioplasty). Results: cTnI serum elevations occurred in 21(45.7%) of the patients after the PCI. At the end of the follow up period, 11(23.9%) of the patients presented adverse cardiac events. There was no association between the cTnI serum elevation and the presence of ACE in the follow up. Conclusions: The elevation of cTnI found after a coronary angioplasty with stent implantation was frequent in our sample, but these elevations in serum did not show any association with clinical variables and the occurrence of adverse cardiac events following 12 months / A presença da elevação da troponina I(cTnI) é comum em pacientes submetidos a uma intervenção coronariana percutânea (ICP), porém é questionado se a lesão miocárdica ocorrida na intervenção permite identificar pacientes com maior risco de apresentar eventos cardíacos adversos. Objetivo: O objetivo geral do estudo foi avaliar o comportamento evolutivo imediato dos níveis séricos de troponina I (cTnI), em pacientes submetidos eletivamente à angioplastia coronária com implante de stent , e também, comparar pacientes com alterações séricas pós-procedimento de angioplastia coronária com implante de stent, com as variáveis clínicas e a ocorrência de eventos cardíacos adversos (ECA) no seguimento de 12 meses. Metodologia: Este é um estudo de coorte prospectivo, que avaliou 49 pacientes consecutivos, submetidos à angioplastia coronariana com implante de stent. Fez-se dosagens séricas de cTnI antes e após o procedimento. Pacientes com cut off > 1,0 ng/mL antes do implante foram excluídos, e os demais foram acompanhados em um ano de seguimento, para registro da presença de ECA (óbito, infarto do miocárdio e nova angioplastia). Resultados: Ocorreram elevações séricas de cTnI em 21(45,7%) dos pacientes após a ICP. Ao término do seguimento 11(23,9%) dos pacientes apresentaram eventos cardíacos adversos. A correlação entre a elevação sérica da cTnI e a presença de ECA no seguimento não mostrou associação. Conclusão: A elevação da cTnI encontrada após uma angioplastia coronariana com o implante de stent foi freqüente em nossa amostra, porém estas elevações séricas não apresentaram nenhuma associação com as variáveis clínicas e a ocorrência de eventos cardíacos adversos no seguimento de 12 meses

Aim: The overarching aim of the thesis was to explore the occurrence and clinical importance of two manifestations of myocardial injury; unrecognized myocardial injury (UMI) and altered levels of cardiac biochemical markers in patients with stable coronary artery disease (CAD). Methods: A prospective multicenter cohort study investigated the prevalence, localization, size, and prognostic implication of UMI in 235 patients with stable CAD. Late gadolinium enhancement cardiovascular magnetic resonance (LGE-CMR) imaging and coronary angiography were used. The relationship between UMI and severe CAD and cardiac biochemical markers was explored. In a substudy the short- and longterm individual variation in cardiac troponins I and T (cTnI, cTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) were investigated. Results: The prevalence of UMI was 25%. Subjects with severe CAD were significantly more likely to exhibit UMI than subjects without CAD. There was a strong association between stenosis ≥70% and presence of UMI in the myocardial segments downstream. The presence of UMI was associated with a significant threefold risk of adverse events during follow up. After adjustments UMI was associated with a nonsignificant numerically doubled risk. The levels of cTnI, NT-proBNP, and Galacin-3 were associated with the presence of UMI in univariate analyses. The association between levels of cTnI and presence of UMI remained significant after adjustment. The individual variation in cTnI, cTnT, and NT-proBNP in subjects with stable CAD appeared similar to the biological variation in healthy individuals. Conclusions: UMI is common and is associated with significant CAD, levels of biochemical markers, and an increased risk for adverse events. A change of &gt;50% is required for a reliable short-term change in cardiac troponins, and a rise of &gt;76% or a fall of &gt;43% is required to detect a long-term reliable change in NT-proBNP.

O complexo troponina-tropomiosina regula a contração muscular esquelética e cardíaca. A ligação do cálcio nos sítios regulatórios localizados no domínio N-terminal da troponina C (TnC) induz uma mudança conformacional que remove a ação inibitória da troponina I (TnI) e inicia a contração muscular. Nós usamos fragmentos recombinantes da TnI e uma série de mutantes da TnC para estudar as interações estruturais e regulatórias das diferentes regiões da TnI com os domínios da TnC, TnT e actina-tropomiosina. Nossos resultados indicam que a TnI é organizada em regiões que apresentam funções estruturais e regulatórias e que se ligam de modo antiparalelo com os correspondentes domínios estruturais e regulatórios da TnC. Estudos funcionais mostram que a região inibitória (aminoácidos 103-116) em combinação com a região C-terminal da TnI (TnI103-182) pode regular a atividade ATPásica da acto-miosina de maneira dependente de Ca2+. A regulação não é observada com a região inibitória em combinação com a região N-terminal (TnI116) Estudos de ligação mostram que a região N-terminal da TnI (TnI1-98) interage com o domínio C-terminal da TnC na presença e na ausência de Ca2+ e também interage com a TnT. A região inibitória/C-terminal da TnI (TnI103-182) interage com o domínio N-terminal da TnC de maneira dependente de Ca2+. Baseados nestes resultados, propomos um modelo para a mudança conformacional induzida pelo Ca2+. Neste modelo, a região N-terminal da TnI está ligada fortemente com o domínio C-terminal da TnC na presença ou na ausência de Ca2+. As regiões inibitórias e C-terminal da TnI ligam-se à actina-tropomiosina na ausência de Ca2+ e nos domínios N-terminal e C-terminal da TnC na presença de Ca2+. / The troponin-tropomyosin complex regulates skeletal and cardiac muscle contraction. Calcium binding to the regulatory sites in the N-terminal domain of troponin C (TnC). induces a conformational change which removes the inhibitory action of troponin I (TnI) and initiates muscular contraction. We used recombinant TnI fragments and a series of TnC mutants to study the structural and regulatory interactions between different TnI regions and the domains of TnC, TnT and actin-tropomyosin. Our results indicate that TnI is organized into regions with distinct structural and regulatory functions which bind, in an antiparallel manner, with the corresponding structural and regulatory domains of TnC. Functional studies show that a fragment containing the inhibitory and C-terminal regions of TnI (TnIl03-182) can regulate the actomyosin ATPase in a Ca2+- dependent manner. Regulation was not observed with a fragment containing the N-terminal and inhibitory regions (TnIl-116). Binding studies show that the N-terminal region of TnI (TnI1-98) interacts with the C-terminal domain of TnC in the presence of Ca2+ or Mg2+. The inhibitory/C-terminal region of TnI (TnI103-182) binds to the N-terminal domain of TnC in a Ca2+-dependent manner. Based on these results, we propose a model for the Ca2+ -induced conformational change. In this model the N-terminal region of TnI is bound strongly to the C-terminal domain of TnC in the presence or absence of Ca2+. The inhibitory and C-terminal regions of TnI bind to actin-tropomyosin in the absence of Ca2+ and to tne N- and C-terminal domains of TnC in the presence of Ca2+.

Yes / The development of androgenetic alopecia is associated with a risk of developing cardiovascular diseases, but the association of alopecia areata with cardiovascular diseases in humans is largely unexplored. We measured the plasma level of two common cardiovascular disease markers, cardiac troponin I and Creactive protein, in alopecia areata and androgenetic alopecia-affected subjects. Also, we investigated the possible presence of pro-apoptotic factors in the plasma of hair loss subjects. The mean plasma cardiac troponin I level was highest in alopecia areata subjects, moderately higher in androgenetic alopecia subjects, and lowest in subjects without hair loss (p < 0.05). Alopecia areata subjects not receiving treatments had highest levels of cardiac troponin I (p < 0.05). Alopecia areata plasma samples with high cardiac troponin I levels also induced significantly higher rates of cardiomyocyte apoptosis in cell culture assays. The results suggest the potential for increased heart remodelling. Close monitoring of cardiovascular health in alopecia areata subjects, as well as subsets of androgenetic alopecia patients, may be appropriate. / Canadian Institutes of Health Research (CIHR; MOP-82927).

(1) Background: Patients with severe chronic kidney disease (CKD G4–G5) often have chronically elevated high-sensitivity cardiac troponin T (hs-cTnT) values above the 99th percentile of the upper reference limit. In these patients, optimal cutoff levels for diagnosing non-ST-elevation acute coronary syndrome (NSTE-ACS) requiring revascularization remain undefined. (2) Methods: Of 11,912 patients undergoing coronary angiography from 2012 to 2017 for suspected NSTE-ACS, 325 (3%) had severe CKD. Of these, 290 with available serial hs-cTnT measurements were included, and 300 matched patients with normal renal function were selected as a control cohort. (3) Results: In the CKD cohort, 222 patients (76%) had NSTE-ACS with indication for coronary revascularization. Diagnostic performance was high at presentation and similar to that of the control population (AUC, 95% CI: 0.81, 0.75–0.87 versus 0.85, 0.80–0.89, p = 0.68), and the ROC-derived cutoff value was 4 times higher compared to the conventional 99th percentile. Combining the ROC-derived cutoff levels for hs-cTnT at presentation and absolute 3 h changes, sensitivity increased to 98%, and PPV and NPV improved up to 93% and 86%, respectively. (4) Conclusions: In patients with severe CKD and suspected ACS, the diagnostic accuracy of hs-cTnT for the diagnosis of NSTE-ACS requiring revascularization is improved by using higher assay-specific cutoff levels combined with early absolute changes.

Knowledge about cardiac and inflammatory biomarkers in patients with stable coronary artery disease (CAD) is limited. To address this, we analyzed 3072 patients (36% female) with a median follow-up of 10 years in the Leipzig LIFE Heart Study with suspected CAD with coronary angiography. Selected biomarkers included troponin T (hsTNT), N-terminal pro B-type natriuretic peptide (NT-proBNP), copeptin, C-reactive protein (hsCRP), and interleukin-6 (IL-6). Patients were stratified by CAD severity: CAD0 (no sclerosis), CAD1 (non-obstructive, i.e., stenosis < 50%), and CAD2 (one stenosis 50%). Group comparison (GC) included GC1: CAD0 + 1 vs. CAD2; GC2: CAD0 vs. CAD1 + 2. CAD0, CAD1, and CAD2 were apparent in 1271, 631, and 1170 patients, respectively. Adjusted for classical risk factors, hs-cTnT, NT-proBNP, and IL-6 differed significantly in both GC and hsCRP only in GC2. After multivariate analysis, hs-cTnT, NT-proBNP, and IL-6 remained significant in GC1. In GC2, hs-cTnT (p < 0.001) and copeptin (p = 0.014) reached significance. Ten-year survival in groups CAD0, CAD1, and CAD2 was 88.3%, 77.3%, and 72.4%. Incorporation of hs-cTnT, NT-proBNP, copeptin, and IL-6 improved risk prediction (p < 0.001). The studied cardiac and inflammatory biomarkers enable fast and precise non-invasive identification of mortality risk in CAD patients, allowing the tailoring of primary and secondary CAD prevention.
