LOGIC LAB – Molecular logic lab-on-a-vesicle for intracellular diagnostics
Molecular logic lab-on-a-vesicle for intracellular diagnostics
Program: Horizon 2020
Project leader: RNDr. Mach Mojmír PhD.
Annotation: A dysfunction of cells lining the inner walls of blood vessels, i.e. the endothelium, is the primary cause of many lifestyle related diseases. According to the WHO, those diseases accounted for 60% of all deaths worldwide in 2005. Tailor-made diagnostic tools for early and reliable identification of endothelial dysfunction are urgently needed both in fundamental research and clinical routine, respectively.The Marie Skłodowska-Curie action LOGIC LAB objects to develop and characterize innovative molecular logic gates that can be applied as advanced diagnostic tools for parallel analyte sensing in live mammalian cells. Thereby, providing a unique method to discover endothelial dysfunction and the onset of diseases much easier and earlier than so far.LOGIC LAB creates a multi-faceted and multi-sectoral research environment for the next generation of scientists in order to establish a novel type of molecular logic sensors that reliably operate in biological media – a crucial requirement for their application i.e. as rapid and easy-to-handle tools for intracellular diagnostics.With excellent cross-disciplinary scientific and complementary training provided in the network, we aim to educate highly-skilled young scientists in the fields of chemistry, physics and biology, who will significantly strengthen the international research community in the domain of molecular logic sensing. Thus, in the long term, LOGIC LAB aims to finally bridge the gap between lab bench and biological or medical practice. It is this gap, that so far prevents a wide-ranging use of existing molecular logic gates e.g. for the diagnosis of lifestyle-associated diseases.

EU-CARDIOPROTECT – Realizácia terapeutického potenciálu nových kardioprotektívnych terapií
Realising the therapeutic potential of novel cardioprotective therapies
Program: COST
Project leader: MUDr. Ravingerová Táňa DrSc., FIACS
Annotation: The proposed COST Action will set up a pan-European Research Network of leading experts in cardioprotection, to jointly develop new initiatives and new strategies for finding innovative and more effective approaches to cardioprotection and for optimizing the pre-clinical and clinical evaluation of new cardioprotective therapies, so as to improve their translation into the clinical setting for patient benefit. The COST Action will co-ordinate and strengthen European research in the field of cardioprotection and accelerate scientific progress through the dissemination and sharing of new therapeutic targets, among network members and industrial partners, thereby facilitating the discovery of new cardioprotective therapies. By utilizing the joint expertise of different European network members we will investigate factors which confound the efficacy of new cardioprotection therapies including comorbidities (such as age, diabetes, and hypertension) and co-medications (such as anti-platelet therapies, statins and beta-blockers). Finally, we will set up a European network of research centers for multi-center laboratory testing of new cardioprotective therapies using small and large animal models of acute IRI in order to select those therapies most likely to succeed in the clinical setting. All aspects of this COST Action proposal require a critical mass of partners across a wide geographic distribution across Europe in order to deliver the objectives outlined in this proposal. The discovery of novel signaling pathways and targets underlying cardioprotection both within and outside the cardiomyocyte (WG1 NEW TARGETS), and the testing of different combinations of cardioprotective therapy (WG2 COMBINATION THERAPY) requires investigators with different experience and expertise across Europe. The ability to test the effect of confounders of cardioprotection (WG3 CONFOUNDERS) requires the expertise of different partners in the different co-morbidities and testing of co-medications. Finally, the most important objective of this COST Action proposal, requires the setting up of a Europe-wide research network for (a) multicenter testing of novel cardioprotective therapies using small and large animal models (WG4 CONSORTIUM) and (b) testing of novel cardioprotective therapies in proof-of-concept clinical studies and optimization of multi-center clinical outcome cardioprotection studies. By definition this requires a critical mass of research partners distributed across Europe.

Study of the triggering mechanisms and transmission of cardioprotective signals induced by noninvasive adaptive stimuli
Program: Inter-academic agreement
Project leader: MUDr. Ravingerová Táňa DrSc., FIACS
Annotation: Cardiovascular diseases are one of the leading causes of mortality in modern society and predicted to rise over the coming decades, due to aging population, longer survival after myocardial infarction, and incidence of civilization diseases. Research pointed out to the protective effects of phenomenon termed ischemic preconditioning (IPC), especially its novel clinically acceptable and safer forms. Currently, cellular mechanisms activated by stimuli like exercise, hypoxia and PC of the remote organ are not yet completely clear as compared with the classiccal IPC. For that reason, pathological animal models (myocardial ischemia, hypertension, d. mellitus, dyslipidemia) and aged animals will be used. Acute PC-like settings of above mentioned interventions, and their longer lasting adaptation modalities will be tested in the in vivo and the ex vivo rats using relevant methodology (combination of physiological, pharmacological and biochemical techniques). The results obtained in this project may lead to development of novel or modified therapeutic strategies to manage myocardial ischemia in patients.

Multi-target paradigm for innovative ligand identification in the drug discovery process
Program: COST
Project leader: RNDr. Májeková Magdaléna PhD.
Annotation: The aim of this COST Action is to join highly-qualified research teams working in disciplines around the field of medicinal chemistry, into a novel network devoted to the multi-target issue in drug discovery. The choice of this theme is related to its marked multidisciplinary character, which can ensure a strong interaction among all COST Action participants. Currently, an important and emerging issue in modern drug discovery is to design novel or identify existing bioactive compounds, endowed with the capability to interact selectively with two or more macromolecular targets, exerting their effects against certain therapeutic goals in a synergic fashion. This leading concept stimulated this COST Action focusing on novel ligands able to recognize selected multiple targets, to promote closer scientific links among European research groups involved in medicinal chemistry field at both academic and industrial level. The research competencies of the network will span around medicinal chemistry, from synthetic chemistry, natural products and biophysics to theoretical chemistry, molecular modelling and biological screening.

Vplyv fruktózovej diéty v experimentálnych modeloch metabolického syndrómu a u zdravých jedincov: návrh účinnej farmakologickej liečby
Effect of fructose diet in experimental models of metabolic syndrome and in healthy subjects: proposal of effective pharmacological treatment
Program: VEGA
Project leader: RNDr. Gáspárová Zdenka PhD.
Annotation: The project will contribute to the knowledge about etiopathogenesis of metabolic syndrome (MetS). It extend the current project, where we study the impact of high-fat and high-fat-high-fructose diet on hypertriacylglycerolemic(HTG) rats. Chronic diseases such as MetS are generally multifactorial. Thus in their origin and development play a role not only environment (diet, physical activity, stress) but also genetic predisposition. In the new project, we will examine effect of fructose diet (FD) on various animal models (spontaneously hypertensive, HTG, Zucker obese/nonobese and Wistar healthy rats) and find which main risk factor of MetS together with FD cause the most serious damage. We will test the effect of the prospective pyridoindole SMe1EC2 and omega-3 fatty acids on the established model. By combining of these drugs, we expect increased effect on a number of risk factors of cardiovascular and cerebrovascular diseases without causing adverse effects, thus a proposal for a new more effective treatment.

Nitroso-sulphide signal pathway – novel regulator vasoactive effects in different types of arterial hypertension
Program: VEGA
Project leader: RNDr. Čačányiová Soňa PhD.
Annotation: Nitric oxide (NO) and hydrogen sulphide (H2S) belong to important gaseous molecules engaged to the regulation of arterial tone in normotensive conditions. NO and H2S interaction includes a formation of new products which are part of an original nitroso-sulphide signalling pathway. Our previous experiments in Wistar rats demonstrated that these new signal molecules triggered a specific vasoactive response, different from the effect evoked by NO and H2S. In condition of arterial hypertension, the vasoactive effects of the novel signalisation have not been described yet. The aim of this project is to characterise the role of NO and H2S as well as of the nitroso-sulphide signalling pathway in different animal models of hypertension: essential (SHR), NO-deficient and also metabolic syndrome (hypertriglyceridemia – HTG). A simultaneous investigation of human vessels isolated from patients with hypertension and dyslipidemia represents an appropriate way how to associate results of basic research with clin. practise.

Nové látky pre prevenciu a terapiu ochorení spôsobených toxicitou glukózy
Novel compounds in prevention and treatment of diseases caused by glucose toxicity
Program: VEGA
Project leader: RNDr. Májeková Magdaléna PhD.
Annotation: In the long term lasting plasma glucose level may affect the course of physiological processes through numerousmetabolic pathways. A polyol pathway ranks among the important mechanisms of glucose toxicity and its mainenzyme – aldose reductase – is a frequent target in design of drugs reducing the progress of chronic diabeticcomplications. Another target could be introduced by calcium homeostasis in cells, as the cytosolic calcium levelis an important factor for many physiological processes, e.g. the insulin secretion. A modulation of calcium pumpSERCA becomes another mechanism for the manifestation of glucose toxicity. The aim of our project is to findnew compounds with polypharmacological effect, by means of combinatorial library of potential aldose reductaseinhibitors and actual knowledge on SERCA activity.

RIDD – Výskum magnetických foriem železa v rozvoji kardiovaskulárnych chorôb a porúch správania
Research of magnetic forms of iron in development of cardiovascular diseases and behavioural disorders
Program: SRDA
Project leader: RNDr. Bernátová Iveta DrSc.
Annotation: This project proposal is focused on the investigation of the role of iron in development of cardiovascular and behavioural disorders, prevalence of which is increasing during aging. The aim of this project is to investigate theimpact of aging on the metabolism of biogenic iron and its magnetic properties in association with metabolic and functional alterations in the cardiovascular system and brain in rats with various genetic predispositions tohypertension. We will determine the molecular biological changes on the level of gene expression, their encoded proteins and the activities of the enzymes involved in the endogenous antioxidant protection, the regulation of nitric oxide production and cell death due to ferroptosis in course of aging. We will also investigate the impact ofexogenously administered iron in the form of the biocompatible ultrasmall superparamagnetic iron oxide nanoparticles (USPIONs) on blood pressure regulation and function of the heart and blood vessels in conditions of normotension, chronically increased blood pressure and acute stress (i.e. acutely elevated blood pressure).Results achieved in this project will contribute to better understanding of the effects of the altered iron metabolism, magnetic forms of bodily iron, as well as iron in the form of USPIONs, on the cardiovascular andcentral nervous systems and to prevention of cardiovascular risk resulting from the use of USPIONs in targeted drug delivery or as the contrast materials for new imaging methods in medicine.

Mechanizmy zahrnuté v endotelovej dysfunkcii indukovanej kyselinou močovou v závislosti od veku a genetickej predispozície k hypertenzii
Mechanisms involved in uric acid-induced endothelial dysfunction depending on the age and genetic predisposition to hypertension
Program: VEGA
Project leader: MUDr. RNDr. Púzserová Angelika PhD.
Annotation: Studies have shown a significant relationship between increased concentration of uric acid in the blood (hyperuricaemia) and cardiovascular diseases, including hypertension. But there is little information on the mechanisms by which uric acid can lead to end-organ damage. Hyperuricaemia combined with hypertension is associated with endothelial dysfunction. However, the mechanisms by which hyperuricaemia causes endothelial dysfunction are not clarified. This project aims to clarify the relationship of hyperuricaemia and hypertension, especially in terms of endothelial function. The aim is to bring new results highlighting the impact of elevated concentrations of uric acid on the endothelium, and to reveal the mechanisms involved in endothelial dysfunction in conductive and resistant arteries isolated from peri-pubertal and adult normotensive, prehypertensive and hypertensive rats. The results will contribute to the knowledge about pathophysiology of hyperuricaemia-induced endothelial dysfunction.

Redoxná homeostáza, proteostáza a zápal ako potenciálne ciele pre ovplyvnenie starnutia a s ním spojených ochorení: Modulácia pomocou látok prírodného a syntetického pôvodu
Redox Homeostasis, Proteostasis and Inflammation as Potential Targets For Influencing Ageing and Age-Related Diseases: Modulation by the compounds of natural and synthetic origin
Program: VEGA
Project leader: Ing. Račková Lucia PhD.
Annotation: Ageing is a natural and inevitable phenomenon which is also the main risk factor for the serious diseases. Free-radical theory of ageing states that organisms age because cells accumulate free radical damage over time. These changes are significantly amplified by the decline in proteolytic capacity. Microglia, as the main immune effector cells of the CNS, undergo these alterations as well. This results in their chronic activation and increased risk of neurodegeneration. The aim of the project is to investigate the potential of compounds of natural and synthetic origin to up-regulate Nrf-2/Keap-1 signalling pathway (in particular, the activation of genes responsible for maintenance of redox homeostasis and proteostasis), also in view of their simultaneous down-regulation of NFkB in microglia. Subject of the project will be also investigation of postranslantional modifications in the regulatory mechanisms of proteolysis in microglial cells.

Annotation: The present project is oriented to obtain new data concerning the maintenance of intracellular homeostasis of sodium, representing one of the unavoidable factors for appropriate regulation of cellular viability, after application of radiotherapy. Using in vivo model (rat) we will investigate the influence of gamma irradiation on the cerebral and renal Na,K-ATPase which is one of the crucial systems in maintaining appropriate intracellular concentration of sodium ions. The data will contribute to elucidation of molecular background of processes involved inmaintaining the cell’s viability in kidney and in brain from the aspect of possible protection of the organism against deleterious side-effects of radiotherapy.

Project leader: RNDr. Bernátová Iveta DrSc.
Annotation: This project will investigate the effect of ultrasmall superparamagnetic iron oxide nanoparticles (USPIONs) on function and structure of the arterial wall and the heart in rats with high blood pressure. We will investigate if acute stress and chronic high blood pressure can facilitate the USPIONs uptake in the arterial wall and heart, tomodify cardiovascular function, including blood pressure regulation and to induce metabolic disorders, oxidative damage and alterations of the Fe2+/Fe3+ ratio in the heart and vasculature. We will investigate if L-type ofvoltage-dependent calcium channels is involved in iron uptake after USPIONs treatment. Results achieved in this project will contribute to better understanding of USPIONs effects on the cardiovascular system in conditions ofacute stress and high blood pressure as well as on prevention of cardiovascular risk resulting from the use of USPIONs in targeted drug delivery.

DYSRPONEP – Dynamika srdcového poškodenia: úloha nekroptotickej bunkovej smrti a prežívania kardiomyocytov.
Dynamics of myocardial damage: a role of necroptotic cell death and survival of cardiomyocytes.
Program: SRDA
Project leader: MUDr. Ravingerová Táňa DrSc., FIACS
Annotation: Cardiomyocytes have a limited capability to proliferate, self-renew and repair. Therefore, the number of cardiac cells during postnatal development determines how the heart can deal with stress and workload demands. Both sudden acute or chronic progressive loss of heart cells are involved in the development of ventricular dysfunction and the progression of heart failure (HF). In cardiomyocyte loss, apoptosis seems to play a minor role comparedto necrosis. In line with this, we have found that markers of a newly described form of regulated necrosis – necroptosis are increased in human failing hearts whereas apoptotic ones are unchanged. Although it has been proposed that these markers form a cytotoxic complex, it is unclear how it induces necroptotic cell death. In this process, a protein RIP1 plays an important role. However, when it is polyubiquitinated it may trigger pro-survivalpathways instead. Stimuli, which preferentially trigger RIP1-mediated cell survival at the expense of cell death, are mostly unknown. In this project, we will study the cytotoxic action of necroptotic complexes with respect totranslocation into cell structures, disturbed ion homeostasis and oxidative stress. In addition, we will study whichRIP1-associated signaling is triggered during cell survival (eg. ischemic preconditioning – IPC) and which RIP1 pathways lead to the contrary, death of cardiac cells in acute myocardial infarction and during the development of HF of various origin. By using a necroptosis inhibitor, we will try to determine whether it affects IPC-induced cardioprotection with respect to cell viability and whether its time-dependent application can relieve remodeling and cardiac dysfunction due to myocardial infarction or induce regression of damage. Cardiomoycytes, isolated hearts and in vivo studies will be used to investigate signaling pathways and autocrine/paracrine and systemwide responses to a primary impulz that induces the damage/ adaptation of the heart.

MEDMEX – Kompenzačné ochranné mechanizmy ako účinný nástroj voči zvýšenej energetickej deficiencii patologicky zaťaženého myokardu: Výhodná perspektíva v modernej experimentálnej kardioprotekcii.
Study of endogenous compensatory mechanisms effective against energy deficiency in pathologycally loaded myocardium: Innovative approaches in experimental cardioprotection.
Program: SRDA
Project leader: Ing. Ferko Miroslav PhD.
Annotation: Research on field of compensatory mechanisms appears to be promising method for endogenous protection inpathologically loaded myocardium under condition of increased energy demands. The project aims to contributeto the knowledge in the field of experimental cardiology and point to new, alternative cardioprotective proceduresagainst ischemia-reperfusion injury. It is necessary to study the protective signaling pathways, propose potentialcardiomarkers and identify positive functional changes observed at the level of cardiac mitochondria and heart itsself for comprehensive understanding of the onset and progression of mechanisms of endogenous myocardialprotection leading to effective compensation against energy deficiency in ischemia/reperfusion injury. Severalapproaches utilize processes of endogenous protection to achieve cardioprotection, such as ischemic andpharmacological preconditioning, clinically applicable „remote“ ischemic preconditioning (RIP) as well asexperimental streptozotocine-induced diabetes mellitus in acute state. Coexistence of several comorbidities (hypercholesterolaemia, hypertension) suppress mechanisms of cell signaling involved in protective effect ofischemic preconditioning that promotes necrotic and apoptotic processes in the myocytes during ischemiareperfusionchallenge and also reduces energy production. With respect to bioenergetics and the role ofmitochondria involved in the execution phase of cardioprotection as a common mechanism in various types ofadaptive phenomena, the information is scarse up to date. It is expected that the project will help to characterizethe changes caused by functional remodeling of the mitochondrial membrane, and provide a new and currentlyabsenting information on regulation of mechanisms against increased enegetic demands resulting in myocardialsurvival.

NO-NEW-REG – Nové regulačné účinky oxidu dusnatého a ich úloha v rozvoji esenciálnej hypertenzie
New regulatory effects of nitric oxide and their role in the development of essential hypertension
Program: SRDA
Project leader: RNDr. Čačányiová Soňa PhD.
Annotation: High blood pressure is a main risk factor in sustained increased morbidity and mortality of humans suffering cardiovascular diseases. Understanding of causes leading to hypertension enable to reveal new preventive andtherapeutic decisions. A new regulatory system involved in vessel tree regulation seems to be neuronal NOsynthase (nNOS) and its interactions with other regulatory systems. On the level of the kidney nNOS signal pathway interferes with renin-angiotensin system (RAS) and sulfide signalization (H2S), and the interactionsamong them are the unexplored area of regulatory mechanisms. nNOS in macula densa stimulate renin syntesis and via it influences RAS and sympathetic nerve system, on the other hand, H2S inhibits renin synthesis. Moreover, the regulatory pathways of nNOS and also endothelial eNOS could interact with endogenous NOSinhibitor, asymmetric dimetylarginine ADMA, on local as well as systemic level. The aim of the project is to study the effect of interactions of NO/nNOS/eNOS signalization with mentioned regulatory pathways (RAS, H2S,ADMA) on cardiovascular system and to find out their role in the specificity of nNOS and/or eNOS action in the conditions of essential hypertension. The availability of the results will be reached via using complex approach(functional, molecular, morphological). Moreover, on the level of acute experiments, we will confront selectedbiochemical markers of perivascular adipose tissue (plasma/serum) as well as vasoactive responses of arteriesisolated from normotensive and hypertensive rats with biochemical markers and reactivity of vessels isolated after nephrectomy from normotensive patients and patients with essential hypertension.

SCAVRAD – Ochrana srdca v situáciách zvýšenej produkcie voľných kyslíkových radikálov: Radiačné a reperfúzne poškodenie.
Protection of the heart in situations of increased production of oxygen free radicals: Radiation and reperfusion injury.
Program: SRDA
Project leader: D.h.c., Prof., MUDr. Slezák Ján DrSc., FIACS
Annotation: According to statistics, cardiovascular and cancer are the main cause of more than 93% of the global morbidityand mortality.One of the most used methods to treat patients with cancer is radiotherapy, which uses ionizing radiation.Ionizing radiation damages the cancer cells, leading to their apoptosis and to potential patient recovery.However, during irradiation of cancer cells may also occur unintended exposure of surrounding healthy tissue,which in turn can cause serious health complications including radiation-induced heart disease. Ionising radiationacts directly on the DNA of cells, or indirectly through the formation of free radicals, which then damage theindividual organelles of cells or DNA. Production of oxygen free radicals, which in addition have a signalingfunction, at higher concentrations have toxic effects on all parts of the heart and blood vessels, is a commondenominator of both ionizing radiation and inflammation, as well as ischemic and reperfusion injury. Therefore,research in this field, and finding novel suitable materials which can positively influence the effects of over

Prenatálne a postnatálne účinky ligandov δ a µ opioidných receptorov na vývoj a funkciu hipokampu
Prenatal and postnatal effects of δ and µ opioid receptor ligands on the hippocampal development and function
Program: SRDA
Project leader: RNDr. Dubovický Michal CSc.
Annotation: Ligands of opioid receptors δ (DOR) and µ opioid receptors (MOR) are commonly used in treatment of severe acute and chronic pain. DORs are involved also in mood disorders like depression and anxiety, which are related to the hippocampal function. Treatment with DOR ligands does not result in adverse effects including addiction, which are common with MOR ligands. However, much less is known about DOR – activated signaling pathways than about MOR – activated pathways. We will analyze the effect of acute (seconds to minutes) and chronic (hours to days) in in vitro and in vivo (prenatal and postnatal) administration of DOR ligands on the morphological and electrophysiological properties of rat hippocampal neurons and compare them with effects of MOR ligands and with effects of ligands specific for MOR-DOR heteromers. Further, involvement of calcium transporting proteins in signal transduction pathways activated by DORs and MORs ligands will be addressed by molecular biology methods. Possible remodeling of the dendritic spines will be investigated using transmission electron microscopy. Effect of DOR ligands on hippocampal plasticity in control and stressed rats will be examined using behavioral tests and molecular neuroscience techniques. Excitability will be investigated in primary culture of hippocampal neurons by patch clamp and in situ by in vivo electrophysiology. Both models enable to follow effects of acute and chronic drug application as well as possible receptor desensitization and offer complementary advantages. Primary neuronal culture is the possibility to visually identify neurons, characterize in details both action potentials and underlying ionic currents and to correlate electrophysiology and molecular biology on the same batch of neurons. In vivo electrophysiology offers the possibility to measure neuronal activity within its normal environment including all interactions with other brain parts.

Štúdium anatomicko-funkčných rozdielov v účinkoch aripiprazolu a kvetiapínu, atypických antipsychotík s podobnými terapeutickými vlastnosťami, ale rozdielnym vplyvom na dopaminergické receptory v mozgu, u experimentálnych zvierat
Investigation of anatomical-functional differences between the effects of aripiprazole and quetiapine, atypical antipsychotics with similar therapeutic indications, but different impact on brain dopaminergic receptors, in experimental animals
Program: SRDA
Project leader: RNDr. Mach Mojmír PhD.
Annotation: Antipsychotics (APs) represent a group of drugs used in the treatment of spectrum of psychotic and depressive disorders. However, frequency of ATs treatment is rather increasing than decreasing and growing number of atypical AP drugs have also been emerged over the last few years. In addition, APs treatment is connected with a number of unwanted side effects, such as extrapyramidal syndrome, akathisia, body mass increase, agranulocytosis, tardive dyskinesia, somnolencia, etc. Anatomical-functional investigations are incessantly bringing information about the effects of APs on the activity of neurons and their spatial distribution in the brain, which allows more precisely to define and predict the consequences of the APs treatment. The aim of the present study is to reveal the effect of acute and repeated treatment of two, relatively new atypical APs, aripiprazole (ARI) and quetiapine (QUE), on the activity of neurons in the forebrain and extra forebrain areas of the brain, to identify the phenotype (chemical) character of the targeted neurons, to investigate their impact on the behavior and to compare their impact on the activity of signaling pathways, expression of signaling molecules, and secretion of selected neuropeptides in anatomically precisely defined brain structures. The data of the present project will be new and will serve for the deeper understanding of the biology of serious mental disorders. They also may bring new impulses to the drug developing processing to prepare drugs with more directed and beneficial therapeutic features.

H2S-NO – Štúdium biologických účinkov produktov H2S/NO interakcie a molekulárne mechanizmy ich pôsobenia
Study of biological effects of H2S/NO products and molecular mechanism of their actions
Program: SRDA
Project leader: RNDr. Čačányiová Soňa PhD.
Annotation: Now it is well acknowledged that endogenously produced H2S affects and is involved in regulation of many physiological and pathological functions of living organisms. It is suggested that biological effects of H2S mightnot result from actions of H2S alone, but from its oxidation products, which come from e.g. interaction of H2S with NO. Last four years, our “international” group indentified the following products of H2S and NO interaction:nitrosopersulfide (SSNO−), polysulfides (HSn−) and dinitrososulfite [N-nitrosohydroxylamine-N-sulfonate (SULFI/NO) (Proc Natl Acad Sci U S A. 112, 2015, E4651-E4660). Biological effects and molecular mechanisms of these products are not completely understood Therefore the aim of our project is to explore biological effectsof the products of H2S/NO interactions and to study their molecular mechanism of their actions. Particularly, as a continuation of our research, we will study their effects on rat blood pressure and aortic rings relaxation. Toelucidate molecular mechanisms of their biological effects, we will study their influence on expression ofenzymes that endogenously produce H2S (CBS, CSE and 3-MST), on intracellular membrane channels,concentration of intracellular calcium, lipid peroxidation and their antioxidant properties. Goal of the project isalso to find out, if studied compounds could provide us with information leading to a drug design based on their molecular structure, what could be an object for next application studies and lead to implementation in medical praxis.

Multi-target paradigm for innovative ligand identification in the drug discovery process
Program:
Project leader: RNDr. Májeková Magdaléna PhD.
Annotation: The aim of this COST Action is to join highly-qualified research teams working in disciplines around the field of medicinal chemistry, into a novel network devoted to the multi-target issue in drug discovery. The choice of this theme is related to its marked multidisciplinary character, which can ensure a strong interaction among all COST Action participants. Currently, an important and emerging issue in modern drug discovery is to design novel or identify existing bioactive compounds, endowed with the capability to interact selectively with two or more macromolecular targets, exerting their effects against certain therapeutic goals in a synergic fashion. This leading concept stimulated this COST Action focusing on novel ligands able to recognize selected multiple targets, to promote closer scientific links among European research groups involved in medicinal chemistry field at both academic and industrial level. The research competencies of the network will span around medicinal chemistry, from synthetic chemistry, natural products and biophysics to theoretical chemistry, molecular modelling and biological screening.

Modulácia vápnikovej homeostázy flavonoidmi v pankreatických beta-bunkách za podmienok stresu endoplazmatického retikula
Modulation of calcium homeostasis in pancreatic beta-cells by flavonoids under conditions of endoplasmic reticulum stress
Program: VEGA
Project leader: RNDr. Lomenová Jana PhD.
Annotation: The project is aimed at the evaluation of protective effect of selected flavonoids and their derivatives upon injury to the pancreatic INS-1E ß-cells under conditions of ER stress in terms of reduction of apoptosis, regulation of intracellular calcium, decrease of intracellular ROS/RNS, increase of insulin secretion and regulation of the expression of the Ca2+ regulating proteins. Flavonoids will be selected based on molecular modeling (interaction SERCA – flavonoid) in silico and based on effects on SR/ER Ca2+-ATPase (SERCA) activity in vitro. Endoplasmic reticulum (ER) stress in pancreatic ß-cells will be induced by: i) free fatty acids, ii) cytokines iii) specific SERCA inhibitors such thapsigargin, iv) high glucose/methylglyoxal, v) reactive oxygen/nitrogen species (eg. peroxynitrite).Effect of flavonoids on ER stress will contribute to the understanding of the mechanism of action of these substances potentially useful in the prevention/treatment of type 2 diabetes and its complications.

Prenatal programming of psychiatric diseases: experimental approaches for evaluation of causes and mechanisms of their origin
Program: VEGA
Project leader: RNDr. Mach Mojmír PhD.
Annotation: Incidence of mental diseases in the developed countries has an increasing trend. At least one mental disease occurred per year approximately in 27% of EU inhabitants (more than 82 mil. people). It is estimated that till 2020, depression will be the main cause of morbidity in the developed countries. There are many evidences on neurodevelopmental origin of mental diseases. Various environmental and maternal factors acting during prenatal period and early childhood can increase sensitivity of the individual to anxiety, depression or other mental disorders in later postnatal life. Insufficient oxygen and nutrition supply of tissues, excessive stress or chemical substances and drugs can adversely affect the development of the brain. Objective of the project proposal will be the evaluation of key epigenetic factors which may play an important role in development of mental diseases.Up-to-date molecular biology as well as non-invasive methods of ethological analyses of appropriate animal models will be utilized.

Prevencia hypoxicko-ischemického poškodenia neonatálneho mozgu potkana: testovanie nových spôsobov farmakologickej a nefarmakologickej intervencie
Prevention of hypoxic-ischemic damage of the neonatal rat brain: testing of novel approaches involving pharmacological and non-pharmacological intervention
Program: VEGA
Project leader: RNDr. Juránek Ivo PhD., DrSc.
Annotation: The proposed project is focused on testing novel ways, suggested by our group, to prevent neonatal brain damage resulting from perinatal hypoxic-ischemic (HI) insult, which is one of the most frequent causes ofnewborn mortality and morbidity. So far, there is no effective therapy for neonatal HI encephalopathy. In the present project, newborn rats will be exposed to cerebral HI insult, and brain damage will be followednoninvasively by magnetic-resonance imaging (MRI) and spectroscopy (MRS) in vivo, and neurological deficit by standard neurobehavioral tests. Originality lies in using combination of antiinflammatory omega-3 fatty acids (DHA+EPA) and excitotoxicity inhibitor (MgSO4) against HI damage. Originality is also a in non-pharmacological approach that include combination of mild hypothermia (34°C) and graded reoxygenation (8-12-16-21% O2). Expected results will contribute to better understanding of mechanisms of HI brain damage and to a proposal of effective management of neonates with HI brain insult.

Skúmanie regulačných mechanizmov medzibunkovej komunikácie v srdci pre cielenú ochranu pred jeho funkčným zlyhaním.
Investigation of regulatory mechanisms of cardiac cell-cell communication for targeted protection from heart failure.
Program: VEGA
Project leader: RNDr. Tribulová Narcisa DrSc.
Annotation: Cardiac cell-to-cell communication via gap junction connexin (Cx) channels is essential for synchronised heart function. While disorders in expression, distribution and phosphorylation of Cx in of both human and animal heart diseases promote occurrence of malignant arrhythmias and heart failure. We hypothesize that targetedmodulation of Cx channel function by exogenous and endogenous compounds may be a promising approach to protect proper heart function. Aim of this project is to elucidate mechanisms implicated in regulation ofCx43-mediated cardiac cell-to-cell communication in healthy and diseased heart. Research findings should enhance knowledge of cardiologists in this field and challenge the realization of clinical trials supporting novel approaches in prevention and/or treatment of heart diseases to fight sudden cardiac death.

ENDBIOM – Sledovanie kritických endogénnych biomarkerov a signálnych dráh v hypertenzii a pri kardiovaskulárnych ochoreniach
Study of critical endogenous biomarkers and signaling pathways in hypertension and cardiovascular diseases
Program: VEGA
Project leader: RNDr. Dovinová Ima PhD.
Annotation: Several endogenous factors and signaling pathways contribute to the development of cardiovascular diseases. Activation of the renin-angiotensin and aldosterone system (RAAS), deteriorated relaxation of vasoactive systems producing NO and H2S, as well as an imbalance of redox pathways producing reactive oxygen and nitrogen species (ROS a RNS). Hypertension is a major risk factors of cardiovascular diseases and leads to functional and structural alterations in blood vessel walls. The landmarks of developed hypertension are increased vasoconstriction regulated by RAAS, oxidative stress manifested in increased ROS and RNS, endothelial dysfunction (increased levels of assymetric dimethyl-arginine – ADMA – and homocystein) as well as cardiovascular remodeling (activation of metaloproteinases). Detection, monitoring, and regulation of the critical pathology markers can lead to a better management of hypertension- and metabolic syndrome-related diseases.

Účinok STAT1 a ISG15 inhibítorov na biochemické a morfologické parametre pri experimentálnom infarkte myokardu
The effect of STAT1 and ISG15 inhibitors on biochemical and morphological parameters in experimental myocardial infarction
Program: VEGA
Project leader: RNDr. Cebová Martina PhD.
Annotation: Myocardial infarction (MI) remains a major cause of morbidity and mortality throughout the world. Atherosclerosis,chronic inflammation and metabolic diseases are the main causes of MI. Hypertension is the most serious riskfactors which worsen the prognosis of MI via induction of oxidative and inflammatory mediators. Chronic ischemialeads to irreversible myocardial damage. Reperfusion of myocardium may potentially save myocardial function,paradoxically, this process causes further damage of the myocardium and apoptosis of cardiomyocytes alongwith upregulation of STAT1 and ISG15. Thus, it is important to study different molecules which may block orrevers pathological processes in myocardial reperfusion injury following MI at different levels. Therefore, the aimof our study is to analyze the effects of STAT1 and ISG15 inhibitors on reperfusion injury in the experimentalmodel of MI (ischemia-reperfusion injury after STEMI revascularization) and determination of pathophysiologicalchanges in this process.

Úloha extracelulárnych vezikúl v medziorgánovej komunikácii zahrnutej v kardioprotekcii na diaľku (remote conditioning).
The role of extracellular vesicles in inter-organ communication related to remote cardioprotection
Program: VEGA
Project leader: doc. RNDr. Barteková Monika PhD.
Annotation: Inter-organ communication plays a crucial role in cardioprotection induced by an ischemic (or other) insult on remote organ to the heart, called remote ischemic preconditioning, or remote conditioning in general. Extracellular vesicles (EVs) are membrane-bound structures secreted by a wide range of mammalian cell types that can be secreted and specifically taken up by other cells. Since EVs contain a high concentration of RNAs and proteins, they are of a high interest as potential mediators of remote cardioprotection, and thus for inter-organ signal transfer mechanisms in general. Revealing the role of EVs in communication between different cells and organs as well as identifying substances transported by EVs to be potential mediators of cardioprotection as the main goal of the current project could lead to better understanding of remote cardioprotection and inter-organ communication in general, and rise up new potential targets of therapy of heart ischemia.

Vplyv transkraniálnej stimulácie mozgu jednosmerným prúdom na senzorimotorické vrátkovanie u človeka
Program: VEGA
Project leader: MUDr. Jagla Fedor CSc.
Annotation: The term sensorimotor gating refers to a basic inhibitory process, which prevents processing of and reacting to irrelevant stimuli so that resources can be allocated to salient aspects of the environment. Disrupted gating is considered to play a causal role in the development of psychosis in schizophrenia spectrum disorders. Prefrontal cortex (PFC) is involved in inhibitory control processes and its dysfunction is a hallmark of schizophrenia. Transcranial direct current stimulation stimulation (tDCS) can be used to increase or decrease excitability of neuronal tissue and is increasingly used to modulate human brain activity and cognitive processes. In this project, we will systematically explore in healthy adults the possibility to modulate sensorimotor gating by tDCS of the PFC, which has not been investigated so far. Our findings will bring important new knowledge on the brain mechanisms of sensorimotor gating, pathogenesis of mental disorders and possibilities of their treatment.

Interakcia nitrergickej, neurotrofickej a endokrinnej signalizácie v etiopatogenéze schizofrénie
Interaction of nitrergic, neurotrophic and endocrine signaling in the etiopathogenesis of schizophrenia
Program: SRDA
Project leader: MUDr. Riečanský Igor PhD.
Annotation: Schizophrenia is a common and severe mental disorder but its pathogenesis is yet poorly understood. Susceptibility to schizophrenia is largely genetic but the genetic predisposition is determined in a complex network of interactions between multiple risk genes and environmental factors, resulting in disordered brain development and function. There is increasing evidence that chronic stress and dysregulation of several signaling pathways plays role in the neurodevelopmental impairment underlying schizophrenia. In this project, by adopting a multidisciplinary approach, we will address at several levels (genetic, neurobiological and behavioral) a candidate pathophysiological pathway, involving nitrergic, neurotrophic and stress signaling, which might be importantly involved in the disordered brain development in schizophrenia. A focus on schizophrenia endophenotypes will enable us to integrate findings from human subjects at genetic risk of the disorder with those from a rodent neurodevelopmental model of schizophrenia. This project will bring important new knowledge on the etiopathogenesis of this devastating disorder and potential novel strategies of its treatment.

Návrh a implementácia metodiky pre rehabilitáciu pacientov s bolesťami chrbta s využitím zrakového biofeedbacku
Design and implementation of visual biofeedback for the rehabilitation of mobility deficiencies in patients with low back pain
Program: SRDA
Project leader: Ing. Hlavačka František CSc.
Annotation: The main goal of this project is to design, optimize and implement a specialized method for the improved rehabilitation of mobility deficiencies in patients suffering from low back pain (LBP). The system will be equipped with accurate inertial measuring units embedded with highly sensitive micro-electro-mechanical (MEMS) accelerometers and gyroscopes, as well as a force platform providing input signals that will be processed and displayed back to the patient (visual biofeedback). LBP is a worldwide health problem affecting people of all ages, with recurring symptoms. Based on positive long-term experiences with visual biofeedback, the project strives to design an effective rehabilitation program for the improvement of impaired trunk mobility during sitting, and also impaired balance control during stance in LBP patients. The project not only includes the accurate acquisition of postural data, but also the development of software which will process, interpret and display this data in an easy to understand way. The software is intended to be easily operated and include training tasks that can be personalized to patient specific requirements. The ultimate goal of the project is to implement complex sensor systems capable of accurate measurements but process the data into an easy to use and easy to interpret rehabilitation tool for improving postural and motor function deficiencies in patients suffering from LBP.
