While afterload (pressure overload) induces concentric hypertrophy, elevation of preload (volume overload) yields eccentric hypertrophy and is associated with a better outcome. Here we analysed the proteomic pattern of mice subjected to short-term preload. Methods and Results: Female FVB/N mice were subjected to aortocaval shunt-induced volume overload that leads to an eccentric hypertrophy (left ventricular weight/tibia length +31 %) with sustained systolic heart function at 1 week after operation. Two-dimensional gel electrophoresis (2-DE) followed by mass spectrometric analysis showed alteration in the expression of 25 protein spots representing 21 different proteins. 64 % of these protein spots were up-regulated and 36 % of the protein spots were consistently down-regulated. Interestingly, alpha-1-antitrypsin was down-regulated, indicating higher elastin degradation and possibly contributing to the early dilatation. In addition to contractile and mitochondrial proteins, polymerase I and transcript release factor protein (PTRF) was also up-regulated, possibly contributing to the preload-induced signal transduction. Conclusions: Our findings reveal the proteomic changes of early-stage eccentric myocardial remodeling after volume overload. Induced expression of some of the respiratory chain enzymes suggests a metabolic shift towards an oxidative phosphorylation that might contribute to the favorable remodeling seen in early VO. Down-regulation of alpha-1-antitrypsin might contribute to extracellular matrix remodeling and left ventricular dilatation. We also identified PTRF as a potential signaling regulator of volume overload-induced cardiac hypertrophy."],["dc.identifier.doi","10.1186/s12967-016-0898-5"],["dc.identifier.gro","3141681"],["dc.identifier.isi","000377182700001"],["dc.identifier.pmid","27234427"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/13299"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8784"],["dc.notes.intern","WoS Import 2017-03-10 / Funder: German Research Foundation [SFB1002]"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.publisher","Biomed Central Ltd"],["dc.relation.issn","1479-5876"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Proteomic analysis of short-term preload-induced eccentric cardiac hypertrophy"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

In this study, we generated iPSCs from a patient with dilated cardiomyopathy (DCM) caused by a missense mutation S635A in RNA-binding motif protein 20 (RBM20) and investigated the functionality and cell biology of cardiomyocytes (CMs) derived from patient-specific iPSCs (RBM20-iPSCs). The RBM20-iPSC-CMs showed abnormal distribution of sarcomeric α-actinin and defective calcium handling compared to control-iPSC-CMs, suggesting disorganized myofilament structure and altered calcium machinery in CMs of the RBM20 patient. Engineered heart muscles (EHMs) from RBM20-iPSC-CMs showed that not only active force generation was impaired in RBM20-EHMs but also passive stress of the tissue was decreased, suggesting a higher visco-elasticity of RBM20-EHMs. Furthermore, we observed a reduced titin (TTN) N2B-isoform expression in RBM20-iPSC-CMs by demonstrating a reduction of exon skipping in the PEVK region of TTN and an inhibition of TTN isoform switch. In contrast, in control-iPSC-CMs both TTN isoforms N2B and N2BA were expressed, indicating that the TTN isoform switch occurs already during early cardiogenesis. Using next generation RNA sequencing, we mapped transcriptome and splicing target profiles of RBM20-iPSC-CMs and identified different cardiac gene networks in response to the analyzed RBM20 mutation in cardiac-specific processes. These findings shed the first light on molecular mechanisms of RBM20-dependent pathological cardiac remodeling leading to DCM. Our data demonstrate that iPSC-CMs coupled with EHMs provide a powerful tool for evaluating disease-relevant functional defects and for a deeper mechanistic understanding of alternative splicing-related cardiac diseases."],["dc.identifier.doi","10.1016/j.yjmcc.2017.09.008"],["dc.identifier.gro","3142517"],["dc.identifier.pmid","28941705"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/16493"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/13672"],["dc.identifier.url","https://sfb1002.med.uni-goettingen.de/production/literature/publications/191"],["dc.language.iso","en"],["dc.notes.intern","lifescience updates Crossref Import"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.relation","SFB 1002: Modulatorische Einheiten bei Herzinsuffizienz"],["dc.relation","SFB 1002 | A08: Translationale und posttranslationale Kontrolle trunkierter Titinproteine in Kardiomyozyten von Patienten mit dilatativer Kardiomyopathie"],["dc.relation","SFB 1002 | C04: Fibroblasten-Kardiomyozyten Interaktion im gesunden und erkrankten Herzen: Mechanismen und therapeutische Interventionen bei Kardiofibroblastopathien"],["dc.relation","SFB 1002 | D01: Erholung aus der Herzinsuffizienz – Einfluss von Fibrose und Transkriptionssignatur"],["dc.relation.issn","0022-2828"],["dc.relation.workinggroup","RG Guan (Application of patient-specific induced pluripotent stem cells in disease modelling)"],["dc.relation.workinggroup","RG Hasenfuß (Transition zur Herzinsuffizienz)"],["dc.relation.workinggroup","RG Linke (Kardiovaskuläre Physiologie)"],["dc.relation.workinggroup","RG Sossalla (Kardiovaskuläre experimentelle Elektrophysiologie und Bildgebung)"],["dc.relation.workinggroup","RG Tiburcy (Stem Cell Disease Modeling)"],["dc.relation.workinggroup","RG Zimmermann (Engineered Human Myocardium)"],["dc.rights","CC BY-NC-ND 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by-nc-nd/4.0"],["dc.title","Severe DCM phenotype of patient harboring RBM20 mutation S635A can be modeled by patient-specific induced pluripotent stem cell-derived cardiomyocytes"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Here, we tested the hypothesis that enhanced cardiomyocyte renewal in transgenic mice expressing cyclin D2 would be beneficial during hemodynamic overload. We induced pressure overload by transthoracic aortic constriction (TAC) or volume overload by aortocaval shunt in cyclin D2–expressing and WT mice. Although cyclin D2 expression dramatically improved survival following TAC, it did not confer a survival advantage to mice following aortocaval shunt. Cardiac function decreased following TAC in WT mice, but was preserved in cyclin D2–expressing mice. On the other hand, cardiac structure and function were compromised in response to aortocaval shunt in both WT and cyclin D2–expressing mice. The preserved function and improved survival in cyclin D2–expressing mice after TAC was associated with an approximately 50% increase in cardiomyocyte number and exaggerated cardiac hypertrophy, as indicated by increased septum thickness. Aortocaval shunt did not further impact cardiomyocyte number in mice expressing cyclin D2. Following TAC, cyclin D2 expression attenuated cardiomyocyte hypertrophy, reduced cardiomyocyte apoptosis, fibrosis, calcium/calmodulin–dependent protein kinase IIδ phosphorylation, brain natriuretic peptide expression, and sustained capillarization.

Methods and resultsFVB/N wild-type mice were subjected to VO induced by aortocaval shunt, and were followed by serial echocardiography until in vivo left ventricular ejection fraction was below <50% (13535days). Heart failure was evident from increased lung and liver weight and increased mortality compared with sham. Maladaptive remodelling resulted in significantly reduced sarcomeric titin phosphorylation (causing increased sarcomeric stiffness), whereas interstitial fibrosis was not increased. This was paralleled by re-expression of the fetal gene program, activation of calcium/calmodulin-dependent protein kinase II (CaMKII), decreased protein kinase B (Akt) phosphorylation, high oxidative stress, and increased apoptosis. Consistently, development of HF and mortality were significantly aggravated in Akt-deficient mice. ConclusionTransition to HF in VO is associated with decreased Akt and increased CaMKII signalling pathways together with increased oxidative stress and apoptosis. Lack of interstitial fibrosis together with sarcomeric titin hypophosphorylation indicates an increased stiffness at the sarcomeric but not matrix level in VO-induced HF (in contrast to PO).

Although studied extensively in animal models, data from patients at the compensated disease stage are lacking. We sampled myocardium biopsies from aortic stenosis patients with compensated hypertrophy and moderate heart failure and used transcriptomics to study the transition to failure. Sequencing and comparative analysis of analogous samples of mice with transverse aortic constriction identified 25 candidate genes with similar regulation in response to pressure overload, reflecting highly conserved molecular processes. The gene cysteine-rich secretory protein LCCL domain containing 1 (CRISPLD1) is upregulated in the transition to failure in human and mouse and its function is unknown. Homology to ion channel regulatory toxins suggests a role in Ca2+ cycling. CRISPR/Cas9-mediated loss-of-function leads to dysregulated Ca2+ handling in human-induced pluripotent stem cell-derived cardiomyocytes. The downregulation of prohypertrophic, proapoptotic and Ca2+-signaling pathways upon CRISPLD1-KO and its upregulation in the transition to failure implicates a contribution to adverse remodeling. These findings provide new pathophysiological data on Ca2+ regulation in the transition to failure and novel candidate genes with promising potential for therapeutic interventions."],["dc.identifier.doi","10.1007/s00395-020-0784-4"],["dc.identifier.pmid","32146539"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/70757"],["dc.identifier.url","https://sfb1002.med.uni-goettingen.de/production/literature/publications/350"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-354"],["dc.relation","SFB 1002: Modulatorische Einheiten bei Herzinsuffizienz"],["dc.relation","SFB 1002 | C04: Fibroblasten-Kardiomyozyten Interaktion im gesunden und erkrankten Herzen: Mechanismen und therapeutische Interventionen bei Kardiofibroblastopathien"],["dc.relation","SFB 1002 | D01: Erholung aus der Herzinsuffizienz – Einfluss von Fibrose und Transkriptionssignatur"],["dc.relation","SFB 1002 | D04: Bedeutung der Methylierung von RNA (m6A) und des Histons H3 (H3K4) in der Herzinsuffizienz"],["dc.relation.workinggroup","RG Cyganek (Stem Cell Unit)"],["dc.relation.workinggroup","RG Hasenfuß (Transition zur Herzinsuffizienz)"],["dc.relation.workinggroup","RG Tiburcy (Stem Cell Disease Modeling)"],["dc.relation.workinggroup","RG Toischer (Kardiales Remodeling)"],["dc.rights","CC BY 4.0"],["dc.title","CRISPLD1: a novel conserved target in the transition to human heart failure"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
