Adult sox10+ Cardiomyocytes Contribute to Myocardial Regeneration in the Zebrafish [PDF]

, 2019
During heart regeneration in the zebrafish, fibrotic tissue is replaced by newly formed cardiomyocytes derived from preexisting ones. It is unclear whether the heart is composed of several cardiomyocyte populations bearing different capacity to replace ...

Microenvironmental Reprogramming by 3D Anisotropic Cardiac Extracellular Matrix Induces Nuclear Remodeling and Epigenetic Maturation of Chemically Induced Cardiomyocytes

Advanced Functional Materials, EarlyView.
A 3D anisotropic hydrogel derived from heart extracellular matrix guides cytoskeletal alignment and nuclear remodeling in reprogrammed cardiomyocyte‐like cells. This study reveals how matrix alignment modulates nuclear envelope dynamics and chromatin state, triggering transcriptional and functional maturation.

Sgk1-Dependent Stimulation of Cardiac Na+/H+ Exchanger Nhe1 by Dexamethasone

Cellular Physiology and Biochemistry, 2013
Background/Aims: The serum- and glucocorticoid-inducible kinase Sgk1 contributes to cardiac remodeling and development of heart failure, which is paralelled by Sgk1-dependent stimulation of the cardiac Na+/H+ exchanger Nhe1.

FBPase is in the nuclei of cardiomyocytes [PDF]

FEBS Letters, 2003
Intracellular localization of FBPase in the cardiac muscle of the pig was studied by immunohistochemistry. In contrast to data from skeletal muscle [Gizak, A., Rakus, D. and Dzugaj, A. (2003) Histol. Histopathol. 18, 135–142], in cardiomyocytes FBPase was present not only in the cytoplasm, but surprisingly, also in the nucleus.

Cellular Responses to Mechanical Cues Across Scales: From Fundamental Insights to Translational Potential

Advanced Healthcare Materials, EarlyView.
This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

MicroRNA-Mediated Direct Reprogramming of Human Adult Fibroblasts Toward Cardiac Phenotype

Frontiers in Bioengineering and Biotechnology, 2020
Modulation of microRNA expression holds the promise to achieve direct reprogramming of fibroblasts into cardiomyocyte-like cells as a new strategy for myocardial regeneration after ischemic heart disease.

Direct Cardiac Actions of the Sodium Glucose Co‐Transporter 2 Inhibitor Empagliflozin Improve Myocardial Oxidative Phosphorylation and Attenuate Pressure‐Overload Heart Failure

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background We determined if the sodium glucose co‐transporter 2 inhibitor empagliflozin attenuates pressure overload‐induced heart failure in non‐diabetic mellitus mice by direct cardiac effects and the mechanisms involved. Methods and Results Male C57BL/

Patient‐Derived 3D Heart‐On‐a‐Chip Model of Dilated Cardiomyopathy With Embedded Bead‐Based Mapping of Tissue Contractility

Advanced Healthcare Materials, EarlyView.
A heart‐on‐a‐chip model of dilated cardiomyopathy is developed from patient‐derived induced pluripotent stem cells. The model recapitulates key disease phenotypes and enables functional assessment through integrated bead‐based tracking and pillar deflection measurements.

Prolonged β-adrenergic stimulation disperses ryanodine receptor clusters in cardiomyocytes and has implications for heart failure

eLife, 2022
Ryanodine receptors (RyRs) exhibit dynamic arrangements in cardiomyocytes, and we previously showed that ‘dispersion’ of RyR clusters disrupts Ca2+ homeostasis during heart failure (HF) (Kolstad et al., eLife, 2018).
