Full textThe Raf kinase inhibitor protein (RKIP) is a kinase regulator with a preference for the G protein-coupled receptor kinase 2 (GRK2) in the heart. The mechanism is a direct interaction of GRK2 and RKIP, which is triggered by a PKC-mediated phosphorylation at serine 153 of RKIP. By binding the GRK2, RKIP prevents the GRK2-mediated GPCR-phosphorylation and, thus, desensitisation of GPCR. As a result, inhibition of GRK2-activity positively affects the responsiveness of cardiac G protein-coupled receptors (GPCR). The GPCR primarly responsible for the regulation of the cardiac contractility are the \textbeta-adrenergic receptors (\textbeta AR). Previous work proved an interrelation of RKIP-expression and contractile response of cardiomyocytes and set a basis for the subject of this thesis, dealing with the effects of RKIP-expression on beta-adrenergic signalling, cardiac function and the development of heart failure. The work describes the impact of RKIP on \textbeta-adrenergic signaling in more detail. An important feature of the inhibitory function of RKIP on GRK2 is a specificity for receptor targets (\textbeta AR) with no, or only minor, impact on the cytosolic targets of the GRK2. RKIP also increases \textbeta-adrenergic signalling. This appears in neonatal cardiac myocytes through an increased cAMP-generation, PKA-activity, contractile action and relaxation velocity after \textbeta-adrenergic stimulation. Similarly, RKIP-transgenic mice, with heart specific RKIP-expression, showed higher PKA and CaMKII-activities as well as, a positive inotropy. Analysis of the calcium cycling in these cardiomyocytes provided an explanation for the hypercontractile phenotype: an enhanced calcium reuptake into the sarcoplasmatic reticulum (SR), the resulting higher calcium load of the SR and an increased calcium amplitude in the cytosol during the systole cause the augmented contractile force. Furthermore, it could be ruled out, that two inward rectifying channels - L-type calcium channnel and Ryanodin Receptor 2 contribute to the positve inotropy in RKIP-transgenic mice. Besides, the RKIP-expression had additional protective effects in heart failure development, which were investigated by desease models. Hypertrophy was induced by chronic \textbeta-adrenergic stimulation and heart failure by induction of pressure overload. Under these conditions, RKIP could reduce the development of interstitial fibrosis and the expression of associated marker genes. The occurence of arrhythmias, in particular ectopic beats, was assessed by the analysis of \textit{in vivo} ECG-traces. Rated by the number of ectopic beats RKIP-transgenic mice were also protected against the induction of arrhythmia. The analysis of RKIP-expression in \textbeta AR subtype-KOs (\textbeta\textsubscript{1}KO, \textbeta\textsubscript{2}KO) could relate the different effects of RKIP to the signalling pathways of either \textbeta\textsubscript{1}AR or \textbeta\textsubscript{2}AR. As a result, RKIP effects the positive inotropy through signals of the \textbeta\textsubscript{1}AR and the protection against heart failure-related remodelling processes and arrhythmia through signals of the \textbeta\textsubscript{2}AR. Additionally a major importance could be assigned to the G\textalpha\textsubscript{i} coupling of the \textbeta\textsubscript{2}AR. This capacity of the \textbeta\textsubscript{2}AR can counteract potentially maladaptive signalling of the \textbeta\textsubscript{1}AR. A monitored growth of cardiomyocytes of RKIP-transgenic mice was assessed in greater depth using different markers to differentiate physiological from pathological hypertrophy. Thereby the occurring hypertrophy was characterised as physiological and compensatory. Taken together, these results point towards a balanced activation of both \textbeta AR. They influence each other through downstream signals and are protected from desensitisation and loss of \textbeta-adrenergic responsivness through inhibition of the GRK2 by RKIP. To validate the therapeutic potential of this mode of action, an AAV9-mediated gene therapy was conducted. In this setting, RKIP was able to prevent, or strongly reduce the most prominent changes during heart failure development. Among these are the decline of the left ventricular function, dilation of the left ventricle, development of a pulmonary congestion, interstitial fibrosis and the expression of heart failure associated genes. Moreover, the consequences of RKIP deletion, which are reflected in an accelerated and deteriorated heart failure development, could be reversed by the reexpression of RKIP. This work shows, that RKIP induces an even activation of \textbeta-adrenergic signalling, which results in a positive inotropy with concomitant protective effects. RKIPs mode of action represents a strategy and bears the possibilty to enhance cardiac contractility in the failing heart by stimulation of both \textbeta AR, which is contrary to the common belief

Full textBy phosphorylation, GRK2 inactivates cardiac ß-adrenoreceptors and thereby reduces the contractility of neonatal rat cardiomyocytes. As a natural inhibitor of GRK2, RKIP influences cell signaling when ß-adrenoreceptors are stimulated. The presented research shows that an overexpression of RKIP increases the contractility of neonatal rat cardiomyocytes. The number of spontaneous contractions occurring before and after stimulation with isoproterenol was recorded and a temporal analysis of calcium release and uptake after electrical stimulation was performed. In the unstimulated state, neonatal rat cardiomyocytes which overexpressed wild-type RKIP showed no significant differences in terms of spontaneous contractions compared with the control group. After stimulation with isoproterenol, neonatal rat cardiomyocytes in which wild-type RKIP was overexpressed showed a significantly higher number of occurring spontaneous contractions. Neonatal rat cardiomyocytes overexpressing wild-type RKIP showed an increased calcium release during systole and an accelerated calcium reuptake during diastole. The RKIP mutants RKIPS51V and RKIPS52V were examined regarding their contractility. Neonatal rat cardiomyocytes which overexpressed RKIPS51V and RKIPS52V showed no significant differences compared to the control group in terms of spontaneous contractions or calcium cycling. Since phosphorylation at amino acid position 51 or amino acid position 52 could also be possible without direct effect on contractility, an in vitro kinase assay focusing on PKA and PKC was performed. In the presented work, apart from phosphorylation at S153, no further phosphorylation of RKIP by PKC or PKA could be observed
