The role of sphingosin kinase in cardioprotection
Pospíšilová, Barbora ; Nováková, Olga (advisor) ; Kolář, David (referee)
Sphingosine-1-phosphate (S1P) is bioactive mediator with cardioprotective effect. Sphingosine kinase (SK) is a key enzyme in the synthesis of S1P. It exists in the two isoforms sphingosine kinase 1 and sphingosine kinase 2. Although SK1 has antiapoptotic feature and SK2 has proapoptotic feature both are crucial for the effect of S1P. S1P can act and affect the cellular faith by intracellular or extracellular functioning. Extracellular S1P binds and activates specific cell surface receptors on the plasma membrane. These receptors are members of the group of G protein-coupled receptors. There are tree subtypes of S1P receptors in the heart tissue (S1P1, S1P2, S1P3). Exogenous S1P increases viability of cardiomyocytes after myocardiacal ischemia/reperfusion injury (I/R). It also reduces the infarct size in isolated rat heart. During conditions of ischemic preconditioning (IPC) or postconditioning (IPOST) which consist of the short periods of ischemia before or after major ischemia insult generate S1P. Released S1P increased viability of the cell and faster recovery of hemodynamic functions in the heart tissue. Effects of S1P and its role in cardioprotection are explored in the genetically modified organisms mainly in the mouses. The evidence of the cardioprotective effect of S1P were experiments using...
Role of phospholipases A2 in cardioprotection induced by continuous normobaric hypoxia in rat heart
Kyclerová, Eva ; Nováková, Olga (advisor) ; Novotný, Jiří (referee)
Recently, they are examined various means for activating the endogenous signalling pathways leading to increased resistance of the myocardium from ischemic/reperfusion (I/R) injury. One of them is the adaptation to chronic hypoxia, which has been shown to reduce the incidence and severity of ventricular arrhythmias, improves the recovery of postischemic contractile function of the heart and particularly reduces the extent of myocardial infarction. Since the function of the heart depends on the maintenance of membrane integrity of cardiomyocytes there are very important phospholipase A2 (PLA2) which are involved in the repair of cellular membranes. Also they are an important component of the protective signalling pathways because they cleave membrane phospholipids to produce lipid signalling molecules. Elucidate the role of PLA2 and the precise mechanism of action of signalling pathways leading to cardioprotection could be important for the prevention and treatment of cardiovascular diseases. Therefore, in this thesis we examined the influence of continuous normobaric hypoxia (CNH) to the relative representation of cardiac PLA2 (secretory - sPLA2IIA, calcium-independent - iPLA2, cytosolic - cPLA2α and its phosphorylated form - p-cPLA2α), and proteins involved in the activation and phosphorylation of...

Role of oxidative stress in cardioprotection induced by exercise.
Kyclerová, Eva ; Nováková, Olga (advisor) ; Kašparová, Dita (referee)
Cardiovascular diseases are the major cause of death in developed countries. It is known that heart muscle can activates endogenous protective pathways in response to stress, thereby increasing resistance against ischemia/reperfusion (I/R) injury. Protective pathways involve many signaling molecules and reactive oxygen species (ROS) play an important role among them. ROS are applied in cardioprotection induced by various stimuli, such as chronic hypoxia, preconditioning and also physical exercise. It has been demonstrated that regular physical exercise naturally leads to the positive adaptation to protect heart against injury. The balance between production of ROS and their removal by antioxidant protection system is important for the right functioning of the heart. The overproduction of ROS occurs in pathological conditions such as an I/R leading to oxidative stress contributing to subsequent damage of heart. ROS may contribute not only to the injury but in the mild concentrations, resulting for example from physical exercise, ROS are important signaling molecules involved in series of events leading to cardioprotection. Slightly increased oxidative stress protects the heart by increasing the capacity of antioxidant system, stimulates angiogenesis, activates mitochondrial biogenesis and physiological...

Myocardial cell signaling in spontaneously hypertensive rats with transgenic and congenic expression of CD36
Klevstigová, Martina ; Nováková, Olga (advisor) ; Kalous, Martin (referee) ; Zicha, Josef (referee)
Long-chain fatty acids (LCFA) are the primary energy source in the myocardium and an imbalance in the LCFA and glucose utilization could cause cardiovascular diseases. More than 50% of LCFA uptake by the heart is mediated by the fatty acid translocase CD36 and disruption of its function has been shown to impair cardiovascular functions. The spontaneously hypertensive rat (SHR) harbors a deletion variant of the Cd36 gene that results in reduced LCFA transport into myocytes. Therefore, the main aim of this thesis was to investigate the importance of a functional CD36 to sustain normal physiological functions of the heart. We used SHR and two genetic modified SHR strains, the congenic SHR-4 and the transgenic SHR-Cd36, with fully functional CD36. They differ in the CD36 expression and in the manner how they were derived from the SHR. CD36 has been proven to play a role in the pathogenesis of insulin resistance. Therefore we analyzed the effect of a functional CD36 on insulin resistance and protein kinase C (PKC) expression, which is known to be involved in the mechanism of insulin resistance, in the heart of SHR-4 and SHR. We showed that the SHR-4 had lower serum free fatty acids (FFA) and triacylglycerols (TAG) concentrations, indicating improved insulin sensitivity. Furthermore, SHR-4 had increased...
The role of lactate shuttle in ischemic-reperfusion injury of rat heart adapted to chronic hypoxia
Kolář, David ; Žurmanová, Jitka (advisor) ; Nováková, Olga (referee)
Adaptation to hypoxia is a well-known phenomenon increasing myocardial resistance to ischemia-reperfusion (I/R) injury as an appropriate physical exercise which improves the contractile function of the heart. Lactate is a major energy substrate for the heart muscle during physical activity and hypoxia. The metabolism of lactate was and still is associated with muscle fatigue, but in the last decades it has been considered its significant modulating function of metabolism during exercise at cellular level and whole organism level. It has been shown that its effects might be similar to the effects of hypoxia and its oxidized form, pyruvate, has the cardioprotective effects. The aim of this study was to compare the expression of LDHA and LDHB isoforms between left and right ventricle in the cardioprotective scheme of adaptation to hypoxia. Another objective/goal was to determine the left ventricular response to I/R insult in the perfused heart model adapted to hypoxia compared with the normoxic controls on/at the expression level of both LDH isoforms. Our results showed differences in the LDHA expression in the left and right ventricle and an increased response of the left ventricle to I/R insult in rats adapted to hypoxia which is reflected at the expression level of both isoforms. Key words: heart,...

Šulcová, Alice ; Nováková, Olga (advisor) ; Svěcená, Kateřina (referee)
Name and surname: Alice Šulcová Supervisor: Bc. Olga Nováková, M.Sc. Opponent: ……………………………. Thesis title: The Applications of Constraint-Induced Movement Elements in Therapy in Patients after Brain Injury Abstract: Stroke is a disease with prevalence of 150 to 200 persons per 100 000 in the Czech Republic. It is the third leading cause of death after heart diseases and various types of cancer. Mortality in the Czech Republic is four times higher than in the USA and 40 % of patients die within one year after the event. Constraint-induced movement therapy (CIT) is often described as a method for improving soft skills and gross motor skills, range of motion, self-care activities in ADL with upper or lower affected extremity. This work verifies the conclusions of the various foreign publications in our conditions on two patients after stroke. Self-care activities in ADL was chosen as a marker of improvement in patients receiving CIT. Therapeutic plan of interventions was divided into three periods - 10 one hour intervention for 14 days, 3 months of individual therapy in home conditions, and 10 one hour intervention for 14 days, again. Evaluation of improvement in self-care activities in ADL was conducted by involved observation and studying of the taken video sequences. Input and output tests were...
