In this context several downstream mediators and cascades have been identified to potentially play a role in cardiomyocyte hypertrophy. One of these proteins is the monomeric G protein Rac1. However, until now it is unclear how this essential G protein is activated by alpha(1)-AR agonists and what are the downstream targets inducing cellular growth. By using protein-based as well as pharmacological inhibitors and the shRNA technique, we demonstrate that in neonatal rat cardiomyocytes (NRCM) Rac1 is activated via a cascade involving the alpha(1A)-AR subtype, G(i)beta gamma, the phosphoinositide-3'-kinase and the guanine nucleotide exchange factor Tiam1. We further demonstrate that this signaling induces an increase in protein synthesis, cell size and atrial natriuretic peptide expression. We identified the p21-activated kinase 2 (PAK2) as a downstream effector of Rac1 and were able to link this cascade to the activation of the pro-hypertrophic kinases ERK1/2 and p90RSK. Our data thus reveal a prominent role of the alpha(1A)-AR/G(i)beta gamma/Tiam1-mediated activation of Rac1 and its effector PAK2 in the induction of hypertrophy in NRCM. (C) 2012 Elsevier Ltd.

During cardiac remodeling CF undergo a transition towards a myofibroblast phenotype thereby showing an increased proliferation and migration rate. Both processes involve the remodeling of the cytoskeleton. Since RhoA is known to be a major regulator of the cytoskeleton, we analyzed its role in CF and its effect on myofibroblast characteristics in 2 D and 3D models. Results Downregulation of RhoA was shown to strongly affect the actin cytoskeleton. It decreased the myofibroblast marker alpha-sm-actin, but increased certain fibrosis-associated factors like TGF-beta and collagens. Also, the detailed analysis of CTGF expression demonstrated that the outcome of RhoA signaling strongly depends on the involved stimulus. Furthermore, we show that proliferation of myofibroblasts rely on RhoA and tubulin acetylation. In assays accessing three different types of migration, we demonstrate that RhoA/ROCK/Dia1 are important for 2D migration and the repression of RhoA and Dia1 signaling accelerates 3D migration. Finally, we show that a downregulation of RhoA in CF impacts the viscoelastic and contractile properties of engineered tissues. Conclusion RhoA positively and negatively influences myofibroblast characteristics by differential signaling cascades and depending on environmental conditions. These include gene expression, migration and proliferation. Reduction of RhoA leads to an increased viscoelasticity and a decrease in contractile force in engineered cardiac tissue."],["dc.description.sponsorship","Open-Access Publikationsfonds 2015"],["dc.identifier.doi","10.1371/journal.pone.0137519"],["dc.identifier.gro","3141809"],["dc.identifier.isi","000362511000003"],["dc.identifier.pmid","26448568"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/12214"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/1312"],["dc.identifier.url","https://sfb1002.med.uni-goettingen.de/production/literature/publications/118"],["dc.notes.intern","WoS Import 2017-03-10"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation","SFB 1002: Modulatorische Einheiten bei Herzinsuffizienz"],["dc.relation","SFB 1002 | C02: RhoGTPasen und ihre Bedeutung für die Last-abhängige Myokardfibrose"],["dc.relation","SFB 1002 | C04: Fibroblasten-Kardiomyozyten Interaktion im gesunden und erkrankten Herzen: Mechanismen und therapeutische Interventionen bei Kardiofibroblastopathien"],["dc.relation","SFB 1002 | C06: Mechanismen und Regulation der koronaren Gefäßneubildung"],["dc.relation.issn","1932-6203"],["dc.relation.workinggroup","RG Lutz (G Protein-Coupled Receptor Mediated Signaling)"],["dc.relation.workinggroup","RG Tiburcy (Stem Cell Disease Modeling)"],["dc.relation.workinggroup","RG Zimmermann (Engineered Human Myocardium)"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","RhoA Ambivalently Controls Prominent Myofibroblast Characteritics by Involving Distinct Signaling Routes"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]Details DOI PMID PMC WOS2015Journal Article Research Paper [["dc.bibliographiccitation.firstpage","39"],["dc.bibliographiccitation.journal","Journal of Molecular and Cellular Cardiology"],["dc.bibliographiccitation.lastpage","54"],["dc.bibliographiccitation.volume","88"],["dc.contributor.author","Ongherth, Anita"],["dc.contributor.author","Pasch, Sebastian"],["dc.contributor.author","Wuertz, Christina M."],["dc.contributor.author","Nowak, Karolin"],["dc.contributor.author","Kittana, Naim"],["dc.contributor.author","Weis, Cleo A."],["dc.contributor.author","Jatho, Aline"],["dc.contributor.author","Vettel, Christiane"],["dc.contributor.author","Tiburcy, Malte"],["dc.contributor.author","Toischer, Karl"],["dc.contributor.author","Hasenfuß, Gerd"],["dc.contributor.author","Zimmermann, Wolfram-Hubertus"],["dc.contributor.author","Wieland, Thomas"],["dc.contributor.author","Lutz, Susanne"],["dc.date.accessioned","2017-09-07T11:43:27Z"],["dc.date.available","2017-09-07T11:43:27Z"],["dc.date.issued","2015"],["dc.description.abstract","Cardiac remodeling, a hallmark of heart disease, is associated with intense auto- and paracrine signaling leading to cardiac fibrosis. We hypothesized that the specific mediator of G(q/11)-dependent RhoA activation p63RhoGEF, which is expressed in cardiac fibroblasts, plays a role in the underlying processes. We could show that p63RhoGEF is up-regulated in mouse hearts subjected to transverse aortic constriction (TAC). In an engineered heart muscle model (EHM), p63RhoGEF expression in cardiac fibroblasts increased resting and twitch tensions, and the dominant negative p63 Delta N decreased both. In an engineered connective tissue model (ECT), p63RhoGEF increased tissue stiffness and its knockdown as well as p63 Delta N reduced stiffness. In 2D cultures of neonatal rat cardiac fibroblasts, p63RhoGEF regulated the angiotensin II (Ang II)-dependent RhoA activation, the activation of the serum response factor, and the expression and secretion of the connective tissue growth factor (CTGF). All these processes were inhibited by the knockdown of p63RhoGEF or by p63 Delta N likely based on their negative influence on the actin cytoskeleton. Moreover, we show that p63RhoGEF also regulates CTGF in engineered tissues and correlates with it in the TAC model.

Therefore, we studied the expression and subcellular localization in freshly isolated RASMCs and performed loss of function experiments to analyze its contribution to RhoGTPase activation and functional responses such as proliferation and contraction. By this, we could show that p63RhoGEF is endogenously expressed in RASMCs and acts there as the dominant mediator of the fast angiotensin II (ANG II)-dependent but not of the sphingosine-1-phosphate (S1P)-dependent RhoA activation. p63RhoGEF is not an activator of the concomitant Rac1 activation and functions independently of caveolae. The knockdown of endogenous p63RhoGEF significantly reduced the mitogenic response of ANG II, abolished ANG II-induced stress fiber formation and cell elongation in 2-D culture, and impaired the ANG II-driven contraction in a collagen-based 3-D model. In conclusion, our data provide for the first time evidence that p63RhoGEF is an important mediator of ANG II-dependent RhoA activation in RASMCs and therewith a leading actor in the subsequently triggered cellular processes, such as proliferation and contraction.-Wuertz, C.

Nucleoside diphosphate kinases (NDPKs) are enriched at the plasma membrane of patients with end-stage HF, but the functional consequences of this are largely unknown, particularly for NDPK-C. Here, we investigated the potential role of NDPK-C in cardiac cAMP formation and contractility. Methods: Real-time polymerase chain reaction, (far) Western blot, immunoprecipitation, and immunocytochemistry were used to study the expression, interaction with G proteins, and localization of NDPKs. cAMP levels were determined with immunoassays or fluorescent resonance energy transfer, and contractility was determined in cardiomyocytes (cell shortening) and in vivo (fractional shortening). Results: NDPK-C was essential for the formation of an NDPK-B/G protein complex. Protein and mRNA levels of NDPK-C were upregulated in end-stage human HF, in rats after long-term isoprenaline stimulation through osmotic minipumps, and after incubation of rat neonatal cardiomyocytes with isoprenaline. Isoprenaline also promoted translocation of NDPK-C to the plasma membrane. Overexpression of NDPK-C in cardiomyocytes increased cAMP levels and sensitized cardiomyocytes to isoprenaline-induced augmentation of contractility, whereas NDPK-C knockdown decreased cAMP levels. In vivo, depletion of NDPK-C in zebrafish embryos caused cardiac edema and ventricular dysfunction. NDPK-B knockout mice had unaltered NDPK-C expression but showed contractile dysfunction and exacerbated cardiac remodeling during long-term isoprenaline stimulation. In human end-stage HF, the complex formation between NDPK-C and G(i2) was increased whereas the NDPK-C/G(s) interaction was decreased, producing a switch that may contribute to an NDPK-C-dependent cAMP reduction in HF. Conclusions: Our findings identify NDPK-C as an essential requirement for both the interaction between NDPK isoforms and between NDPK isoforms and G proteins. NDPK-C is a novel critical regulator of -adrenoceptor/cAMP signaling and cardiac contractility. By switching from G(s) to G(i2) activation, NDPK-C may contribute to lower cAMP levels and the related contractile dysfunction in HF."],["dc.identifier.doi","10.1161/CIRCULATIONAHA.116.022852"],["dc.identifier.eissn","1524-4539"],["dc.identifier.isi","000395549700016"],["dc.identifier.issn","0009-7322"],["dc.identifier.pmid","27927712"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/77166"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-354"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","PUB_WoS_Import"],["dc.publisher","Lippincott Williams & Wilkins"],["dc.relation.issn","1524-4539"],["dc.relation.issn","0009-7322"],["dc.title","Nucleoside Diphosphate Kinase-C Suppresses cAMP Formation in Human Heart Failure"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]Details DOI PMID PMC WOS
