Chamber-specific chromatin architecture guides functional interpretation of disease-associated Cis-regulatory elements in human cardiomyocytes S. Haydar, R. Bednarz, P. Laurette, I. Sobitov, N. Díaz i Pedrosa, P. Videm, T. Lueneburg, S. Kuß, H. Lahm, M. Dreßen, M. Krane, C. Schmidt, B. A. Grüning, N. Voigt, K. Streckfuss-Bömeke, R. Gilsbach Nature Communications, 2026 Cis- regulatory elements (CREs) are noncoding DNA regions regulating cell-type-specific gene expression programs by interacting with distal gene promoters. Here, we aim to decode the function and spatial organization of CRE-promoter interactions in human cardiomyocytes. We analyzed the epigenome and chromatin interactions of human male atrial, ventricular, and failing cardiomyocytes. Atrial and ventricular cardiomyocytes harbored chamber-specific CRE-promoter interactions modulating gene expression as confirmed by functional epigenetic silencing. These CRE-promoter interactions explain the distinct contribution of non-coding genetic variants to atrial and ventricular diseases, such as dilated cardiomyopathy and arrhythmias. We dissected the prototypic KCNJ2 locus, encoding a potassium channel associated with ventricular arrhythmia susceptibility. Functional epigenetic silencing confirmed that CREs, harboring QT-duration-associated genetic risk factors, modulate KCNJ2 gene expression levels, alter KCNJ2-dependent channel currents, and affect cardiomyocyte repolarization. The presented human CM-specific chromatin interaction analysis provides key insights into regulatory mechanisms and aids in interpreting genetic risk factors.
Enhancing KLF15 activity in cardiomyocytes: a novel approach to prevent pathological reprogramming and fibrosis via nuclease-deficient dCas9VPR Eric Schoger, Rosa Kim, Federico Bleckwedel, Tomas Peralta, Laura Priesmeier, Janek Fischer, Laura Stengel, Cheila Rocha, Gabriela L. Santos, Susanne Lutz, Etienne Boileau, Nina Baumgarten, Marcel H. Schulz, Christoph Dieterich, Oliver J. Müller, Lukas Cyganek, Alfredo Cabrera-Orefice, Hanna Eberl, Christoph Maack, Katrin Streckfuss-Bömeke, Mario Pavez-Giani, Shirin Doroudgar, Samuel T. Sossalla, Laura C. Zelarayán Signal Transduction and Targeted Therapy, 2026 Transcriptional activity perturbation holds promise for selectively modulating harmful transcriptional networks, but its therapeutic potential remains largely unexplored. We employed a network-based analysis of single-cell heart transcriptomes to identify transcription factor activities linked to pathological cardiomyocytes in vivo. This analysis revealed that transcriptional activity of Krüppel-like factor 15 (KLF15) exhibited the most significant change in pathological cardiomyocytes, characterized by less effective repression of disease-associated genes in stressed hearts, which correlated with reduced KLF15 expression. To restore KLF15 activity, we utilized CRISPR/nuclease-dead (d)Cas9-based transcriptional enhancement (CRISPRa) in cardiomyocytes, which effectively abolished fetal reprogramming by simultaneously suppressing pathological gene expression and restoring metabolic homeostasis under sustained stress conditions. Furthermore, we identified a novel cell-nonautonomous anti-fibrotic effect mediated by cardiomyocyte-fibroblast crosstalk, and revealed the contribution of KLF15-dependent Alpha-2-glycoprotein 1, zinc-binding (AZGP1) regulation in this process. We also elucidated the upstream mechanisms of KLF15 regulation, highlighting its role as a cell-specific downstream target of the broad TGF-β canonical signaling pathway, along with its downstream-dependent mechanisms in human cardiomyocytes. Finally, to enhance the therapeutic potential of this approach, we engineered and validated an adeno-associated viral (AAV) vector with a small CRISPRa system for endogenous regulation in human cardiomyocytes suitable for clinical applications. Overall, we elucidated a regulatory circuit involving TGF-β, KLF15, and AZGP1, which coordinates critical pathological responses through cellular crosstalk between cardiomyocytes and fibroblasts. Importantly, we demonstrated the efficacy of CRISPRa as an epigenetic intervention restoring a critical transcriptional function disrupted in non-genetic heart failure. This approach provides a promising blueprint for future adaptation targeting additional non-hereditary pathologies.
Generation of pluripotent stem cell line (IPWi001-A) and a corresponding CRISPR/Cas9 modified isogenic rescue control (IPWi001-A-1) from a patient with arrhythmia-induced cardiomyopathy harboring a KCNQ1 truncating mutation Meike Anders, Stefanie Hoppe, Hanna Eberl, Sabine Rebs, Aylin Seedorf, Wiebke Maurer, Tillmann Schill, Arne Zibat, Julia K. Unsöld, Gökhan Yigit, Bernd Wollnik, Dirk Vollmann, Samuel Sossalla, Katrin Streckfuss-Bömeke Stem Cell Research, 2026 KCNQ1 functions as a slow rectifying potassium channel during the repolarization of the cardiac action potential, with mutations causing long-QT syndrome 1 and arrhythmias. A genetic link between KCNQ1 mutations and arrhythmia-induced cardiomyopathy (AIC) has not been identified, and the underlying pathways remain elusive. We generated human induced pluripotent stem cells (hiPSCs) from an AIC patient harboring the heterozygous truncating mutation p.W15* in KCNQ1 and corrected the mutation to wildtype using CRISPR/Cas9. The hiPSCs retained full pluripotency, genomic integrity, and differentiation ability. They were differentiated into hiPSC-cardiomyocytes (hiPSC-CM), establishing a patient-specific model to explore potential genetic connections to AIC.
Models of the human heart for biomedical research: Opportunities and challenges Katrin Streckfuss‐Bömeke, Laura C. Zelarayán, Renate B. Schnabel, Nicolle Kränkel, Christoph Maack, Thomas Eschenhagen, Hannah E. Kappler, Ursula Klingmüller, Rafael Kramann, Axel Loewe, Hendrik Milting, Cristina E. Molina, Daniela Panáková, Bruno K. Podesser, Angelika Schnieke, Katrin Schröder, Thomas Seidel, Samuel Sossalla, Callum Zgierski‐Johnston, Wolfram‐Hubertus Zimmermann, Eva A. Rog‐Zielinska, Peter Kohl Physiological Reports, 2026 Model systems that mimic human cardiac structure and function are essential for the development of novel diagnostics and effective treatments for cardiovascular diseases. While non‐human vertebrate models, from zebrafish to pig, remain vital to cardiovascular research, the translatability of findings to human patients is often limited. Therefore, animal experiments should be supplemented with human model systems, including human induced pluripotent stem cell‐derived cells, 3D engineered constructs, and last but not least, native tissue preparations and isolated primary cardiomyocytes. However, while human myocardium remains the gold standard, human heart tissue – and particularly tissue from control hearts–remains scarce, and its use in research is generally restricted to settings where tissue has been excised from diseased or failing hearts. While it is in principle possible to use tissue from rejected non‐failing donor hearts that cannot be transplanted, legal hurdles (e.g., in Germany) can restrict the use of non‐transplanted donor organs in research. Given the challenges associated with accessing and using human tissue in biomedical research, an integrated strategy towards combining non‐human vertebrate models, in silico models, and human tissue‐derived models is recommended, enhancing the chances of successful research and development, and helping bridge the gap between preclinical and clinical research.
A human-on-human assay for detecting anti-myocardial antibodies in patients with myocardial disease Anne Auer, Johanna Siegel, Stasa Janjatovic, Margarete Heinrichs, Stefan Störk, Peter Heuschmann, Caroline Morbach, Katrin Streckfuss-Bömeke, Gustavo C. Ramos, Katrin G. Heinze Frontiers in Immunology, 2026 Adaptive immune responses, particularly the production of anti-myocardial antibodies, have been implicated as critical mediators in myocardial healing and remodeling following myocardial infarction (MI), acute myocarditis (Myo), and heart failure (HF). However, current methods for detecting heart-reactive antibodies in patients are insufficient, as most rely on heart tissue slices from primates or other species. These approaches pose technical, logistical, and ethical challenges, including the risk of false negative results due to lack of inter-species cross-reactivity. To address these limitations, we developed a human cell-based assay to screen for patient-derived serum or plasma reactivity against human cardiomyocytes differentiated from induced pluripotent stem cells (iPSC-CMs). This human-on-human test system can detect cardiomyocyte-specific immunoglobulins present in patient plasma by applying indirect immunofluorescence staining, followed by convenient visualization through either confocal microscopy or standard widefield systems available in clinical laboratories. Overall, this approach provides a physiologically relevant and ethically responsible model for rapid, accurate testing of anti-myocardial antibodies across various clinical settings, thus offering accessible tools to stratify patients with myocardial disease according to their adaptive immune response status.
Deregulation of m6A-RNA methylation impairs adaptive hypertrophic response and drives maladaptation via mTORC1-S6K1-hyperactivation and autophagy impairment Karthika Annamalai, Soniya Dilliker, Eric Buchholz, Ricardo Castro-Hernández, Nikita Panyam, Alessa Pommeranz, Pascal Wiederhake, Nelly Wery von Limont, Nina Hempel, Verena Ebner, Surabhi Swarnkar, Belal A. Mohamed, Katrin Streckfuss-Bömeke, Sabine Steffens, Stephan Herzig, Antje Ebert, Andre Fischer, Karl Toischer Cell Communication and Signaling, 2025 Pressure overload first leads to compensated hypertrophy and secondary to heart failure. m6A-RNA methylation is a fast process for the adaptation of cell composition. m6A-RNA-methylation is regulated by the demethylase, fat mass and obesity-associated protein ( FTO), and FTO protein levels are diminished in heart failure. Cardiomyocyte-specific FTO-transgenic/knockout-mice have shown the relevance of FTO in pressure overload remodeling. However, its functional downstream regulatory mechanisms are still unclear. In this study, we discover the harmful signaling pathways that are triggered by m6A imbalance and FTO loss, which eventually lead to adverse cardiac remodeling and heart failure. FTOcKO animals were generated by crossing FTO fl/fl mice with \(\alpha\) - MHC Cre mice using Cre-lox system. Control and the FTOcKO animals groups were subjected to TAC (transverse aortic constriction) surgery. Echocardiography was performed 1-week post-TAC surgery. MeRIP (m6A RNA immunoprecipitation) sequencing was performed from the heart tissues of mice after one week TAC surgery. Additionally, the mechanistical interrelation between the signaling pathways during FTO loss and adverse cardiac remodeling were investigated in human iPS-CMs (hiPS-CMs). One week post-TAC surgery, FTOcKO mice showed impaired cardiac function (EF: CreC TAC (45%) vs. FTOcKO TAC (25%), p < 0.0001) and increased LVID (CreC TAC(3.9 mm) vs. FTOcKO TAC (4.8 mm), p < 0.0001), indicating a lack of adaption to pressure overload. Knockdown of FTO in hiPS-cardiomyocytes also reduced endothelin-induced hypertrophic response. MeRIP-seq data of FTOcKO mice showed that the differentially hypermethylated transcripts were associated with cardiac apoptosis inhibition (CDK1, CFLAR), mTORC1 signaling pathway (AKT1S1) and autophagy regulation (TFEB). mTORC1 was identified as a central player of dysregulation with hyperactivation of its canonical substrates phospho-S6K1 (Thr 389) and phospho-S6 (ser235/236) ex-vivo (FTOcKO) and in-vitro (FTO-KD-hiPS-CMs). Moreover, FTO-deficient cardiomyocytes cause autophagic flux impairment and defective autophagy. The effect of atrophy and induced apoptosis upon FTO-m6A imbalance could be rescued by pharmacological inhibiton of the mTORC1-S6K1 pathway. Downregulation of FTO leads to mTORC1-S6K1 hyperactivation that shift the compensative hypertrophic response to atrophy and apoptosis leading to progressive heart failure. These findings might pave the way for the development of novel therapeutic targets for the early phases of heart failure treatments.
Impaired Atrial Mitochondrial Calcium Handling in Patients With Atrial Fibrillation Julius Ryan D. Pronto, Fleur E. Mason, Eva A. Rog-Zielinska, Funsho E.

Knollmann, Stefan Neef, Katrin Streckfuss-Bömeke, Constanze Schmidt, Christoph Maack, Niels Voigt Circulation Research, 2025 BACKGROUND: Mitochondrial calcium (Ca 2+ ) is a key regulator of cardiac energetics by stimulating the tricarboxylic acid cycle during elevated workload. Atrial fibrillation (AF) is associated with a reduction in cytosolic Ca 2+ transient amplitude, but its effect on mitochondrial Ca 2+ handling and cellular redox state has not been explored. METHODS: Cardiac myocytes isolated from patient-derived right atrial biopsies were subjected to workload transitions using patch-clamp stimulation and β-adrenergic stimulation (isoproterenol). In conjunction, nicotinamide adenine dinucleotide (phosphate)/flavin adenine dinucleotide (NAD[P]H/FAD) autofluorescence, cytosolic and mitochondrial [Ca 2+ ] were monitored using epifluorescence microscopy. Sarcoplasmic reticulum and mitochondria were imaged using electron microscopy and tomography and stimulated emission depletion microscopy. The effects of the mitochondrial Ca 2+ uptake enhancer ezetimibe on proarrhythmic activity in atrial myocytes and on AF burden in patients were investigated. RESULTS: Mitochondrial Ca 2+ accumulation during increased workload was blunted in AF, and was associated with impaired regeneration of nicotinamide adenine dinucleotide and flavin adenine dinucleotide. Nanoscale imaging revealed spatial disorganization of sarcoplasmic reticulum and mitochondria, associated with microtubule destabilization. This was confirmed in human induced pluripotent stem cell–derived cardiac myocytes, where treatment with the microtubule destabilizer nocodazole displaced mitochondria and increased proarrhythmic Ca 2+ sparks, which were rescued by MitoTEMPO. Ezetimibe also reduced the occurrence of arrhythmogenic Ca 2+ release events both in AF myocytes and nocodazole-treated human induced pluripotent stem cell–derived cardiac myocytes. Retrospective patient analysis also revealed a reduced AF burden in patients on ezetimibe treatment. CONCLUSIONS: Mitochondrial Ca 2+ uptake and accumulation are impaired in atrial myocytes from patients with AF. The disturbed spatial association between sarcoplasmic reticulum and mitochondria driven by destabilized microtubules may underlie impaired Ca 2+ transfer in AF. Enhancing mitochondrial Ca 2+ uptake potentially protects against arrhythmogenic events.
Arrhythpy: an automated tool to quantify and classify arrhythmias in Ca2+ transients of iPSC-cardiomyocytes Karim Ajmail, Charlotte Brand, Thomas Borchert, Benjamin Meder, Sabine Rebs, Katrin Streckfuss-Bömeke American Journal of Physiology Heart and Circulatory Physiology, 2025 Arrhythmias in calcium transients are easy to detect by human perception. However, quantifying these arrhythmias in a computer-readable manner remains challenging. To address this, we developed Arrhythpy, an automated tool that measures arrhythmias in iPSC-derived cardiomyocytes by analyzing Ca2+ transients. Unlike other tools, Arrhythpy directly evaluates arrhythmia levels. It effectively monitors arrhythmias in healthy and diseased iPSC-CMs, including dilated cardiomyopathy and Takotsubo syndrome. Arrhythpy’s flexible framework suits varied cell types and measurement techniques.
Atrial fibrillation in end-stage heart failure: Cellular mechanisms behind CASTLE-HTx Maria Knierim, Nico Hartmann, Wiebke Maurer, Steffen Pabel, Simon Sedej, Dirk von Lewinski, Jan Gummert, Christian Sohns, Katrin Streckfuss‐Bömeke, Samuel Sossalla European Journal of Heart Failure, 2025 Atrial fibrillation (AF) often coexists in patients with heart failure (HF). Rhythm restoration is increasingly recognized as a prognostically relevant strategy in patients with HF and AF. However, compared to other frequent comorbidities like chronic kidney disease or type 2 diabetes, the reciprocal interaction between HF and AF and particularly the impact of AF on the development and progression of HF has not been fully understood and continues to be underestimated.1 Recently, the CASTLE-HTx trial, among others, demonstrated that catheter ablation for AF and the reduction of AF burden improved prognosis even in patients with end-stage HF. This was associated with improved left ventricular systolic function following AF ablation.1-3 Those results clearly underscore the need to explore the largely unknown mechanisms of AF in end-stage HF. To investigate the effects of persisting AF on ventricular function in severe HF, we isolated 15 human ventricular trabeculae from freshly explanted end-stage HF hearts from nine patients in total and seven trabeculae from four non-HF organ donors (non-failing [NF]) as described previously.4 NF samples were acquired from patients whose hearts could not be transplanted due to non-cardiac medical or technical reasons. The cohort of HF patients had a mean age of 60.4 ± 1.6 years (mean ± standard error of the mean), left ventricular ejection fraction of 28.0 ± 3.2% and ischaemic cardiomyopathy in 44.4% of cases. All patients received guideline-directed medical therapy with no significant differences. The isolated trabeculae were subjected to AF simulation by electric stimulation in vitro for up to 8 h using a purpose-made pacing system (C-Pace EM, IonOptix, Westwood, MA, USA) with irregular stimulation intervals (60 bpm with 40% beat-to-beat variability) versus control stimulation (60 bpm with regular intervals). Contractility was assessed at 60 bpm in each group at baseline and intermittently after 2, 4, and 8 h of continuous pacing. To investigate cellular mechanisms of AF in human HF, we utilized a total of nine differentiations of human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CM) generated from two patients with familial dilated cardiomyopathy (DCM) with end-stage HF and three differentiations from one healthy control patient.5 Cardiomyocyte (CM) differentiation and cell culture were performed as previously described.5, 6 Chronic AF simulation for 48 h was performed by continuous pacing of hiPSC-CM in culture using the C-Pace EM pacing system (90 bpm with 30% beat-to-beat variability vs. regular 60 bpm). Intracellular Ca2+ cycling was studied in DCM and healthy hiPSC-CM after 48 h of AF simulation using the Ca2+ sensitive dye Fura-2 as described elsewhere.6 The patch-clamp method in voltage-clamp mode was employed to record action potentials (AP) in DCM and healthy hiPSC-CM after 48 h of AF or control stimulation, following an established protocol.6 All procedures were performed according to the Declaration of Helsinki and were approved by the local ethics committees of the University of Göttingen (ref. no. 10/9/15, 31/9/00) and Medical University of Graz (ref. no. 28-508 ex 15/16). Atrial fibrillation simulation for 8 h resulted in a substantial decrease in systolic contractile force in human end-stage HF trabeculae compared to control (Figure 1). Furthermore, diastolic function rapidly deteriorated due to AF simulation, as represented by a significant increase in diastolic tension and slowed relaxation compared to control stimulation (Figure 1). In contrast, trabeculae from NF hearts did not exhibit a negative contractile response to AF simulation (Figure 1), demonstrating the rapid deterioration of ventricular function solely because of AF in pre-existing HF. Ca2+ cycling measurements were performed in DCM and healthy hiPSC-CM after 48 h of AF simulation or rhythmic control stimulation to investigate potential underlying cellular mechanisms. Continuous AF simulation for 48 h in DCM hiPSC-CM resulted in a substantial reduction of systolic Ca2+ release compared to control stimulation, as measured by reduced Ca2+ transient amplitude (Figure 1). Concomitantly, the intracellular Ca2+ elimination in diastole (elimination constant τ) was significantly slower after AF simulation than upon control stimulation in DCM hiPSC-CM (Figure 1). The latter was likely related to a reduction in SERCA2a activity after AF simulation, leading to slower Ca2+ reuptake to the sarcoplasmic reticulum as evaluated by rapid high-dose caffeine application (Figure 1). Again, these effects could not be observed in healthy hiPSC-CM after 48 h of AF simulation (Figure 1). Furthermore, patch-clamp experiments in DCM hiPSC-CM revealed a significant prolongation of the AP duration (90%) after 48 h of AF simulation compared to rhythmic stimulation in DCM hiPSC-CM, but not in healthy hiPSC-CM (Figure 1). These effects altogether illustrate the detrimental impact of AF on human failing myocardium compared to healthy myocardium. Our translational human myocardium-based experiments demonstrate that AF leads to rapid and severe ventricular contractile dysfunction and cellular functional remodelling in human HF. As Ca2+ is a major determinant of myocardial contractile function, this could be explained mechanistically by adverse Ca2+ cycling alterations in DCM hiPSC-CM in early stages of AF simulation. Furthermore, AF simulation induced a distinct prolongation of the AP in hiPSC-CM, which constitutes an electrophysiological hallmark of HF. Interestingly, in NF myocardium and healthy hiPSC-CM, these effects could not be observed. Recent experimental work from our group has shown similar HF-typical effects of long-term AF simulation on Ca2+ handling and AP morphology, although only after a longer period of AF simulation of 7 days in healthy CM.6, 7 Mechanistically, increased production of reactive oxygen species with oxidative regulation of Ca2+/calmodulin-dependent protein kinase II (CaMKII), along with differential regulation of proteins involved in Ca2+ homeostasis (e.g. reduction of SERCA2a activity) and electrophysiology, have been demonstrated as causal mechanisms for the observed alterations.6 Supporting this pathway and the importance of AF-induced alterations, increased CaMKII and AMP-activated protein kinase activity after AF simulation have been associated with Ca2+ cycling alterations and disturbed fatty acid and glucose metabolism, accompanied by pro-apoptotic pathways in a neonatal rat-CM model.8 Most noteworthy, we here demonstrate that in pre-existing HF adverse effects of AF on myocardial function can be observed earlier and to a greater extent than in healthy myocardium. This highlights the vulnerability of HF ventricular myocardium towards AF and, in context with recent clinical studies like CASTLE-AF or CASTLE-HTx, underscores the importance of timely rhythm restoration and AF burden reduction in pre-existing HF.
