Myocardial Mitochondrial DNA Drives Macrophage Inflammatory Response through STING Signaling in Coxsackievirus B3-Induced Viral Myocarditis

Cells, 2023
Coxsackievirus B3 (CVB3), a single-stranded positive RNA virus, primarily infects cardiac myocytes and is a major causative pathogen for viral myocarditis (VMC), driving cardiac inflammation and organ dysfunction.

Epigenetic regulation of cardiac myocyte differentiation† [PDF]

Frontiers in Genetics, 2014
Cardiac myocytes (CMs) proliferate robustly during fetal life but withdraw permanently from the cell cycle soon after birth and undergo terminal differentiation. This cell cycle exit is associated with the upregulation of a host of adult cardiac-specific genes.

A Comorbidity Model of Myocardial Ischemia/Reperfusion Injury and Hypercholesterolemia in Rat Cardiac Myocyte Cultures

Frontiers in Physiology, 2020
IntroductionThe use of comorbidity models is crucial in cardioprotective drug development. Hypercholesterolemia causes endothelial and myocardial dysfunction, as well as aggravates ischemia/reperfusion (I/R)-induced myocardial injury.

High-Sensitive Cardiospecific Troponins: The Role of Gender-Specific Concentration in the Diagnosis of Acute Coronary Syndrome (Descriptive Review)

Reviews in Cardiovascular Medicine, 2023
Cardiospecific troponins are specifically localized in the troponin-tropomyosin complex and in the cytoplasm of cardiac myocytes. Cardiospecific troponin molecules are released from cardiac myocytes upon their death (irreversible damage in acute coronary

Comprehensive Expression Analysis of Cardiac Fibroblast Growth Factor 23 in Health and Pressure-induced Cardiac Hypertrophy

Frontiers in Cell and Developmental Biology, 2022
Enhanced fibroblast growth factor 23 (FGF23) is associated with left ventricular hypertrophy (LVH) in patients with chronic kidney and heart disease. Experimentally, FGF23 directly induces cardiac hypertrophy and vice versa cardiac hypertrophy stimulates

Hamartomas of mature cardiac myocytes [PDF]

European Heart Journal - Cardiovascular Imaging, 2008
We present two paediatric cases of a very rare, pathologically benign, and primary cardiac tumour composed of mature cardiac myocytes with disorganized cytoarchitecture called hamartoma of mature cardiac myocyte. The patients are usually asymptomatic, may have non-specific electrocardiogram findings, and rarely have associated sudden death.

Immunolocalization of KATP channel subunits in mouse and rat cardiac myocytes and the coronary vasculature. [PDF]

, 2005
BACKGROUND: Electrophysiological data suggest that cardiac KATP channels consist of Kir6.2 and SUR2A subunits, but the distribution of these (and other KATP channel subunits) is poorly defined.

Cardiac Myocyte Exosome Isolation [PDF]

, 2016
Exosomes are cell-derived small extracellular membrane vesicles (50-100 nm in diameter) actively secreted by a number of healthy and diseased cell types. Exosomes can mediate cellular, tissue, and organ level micro communication under normal and pathological conditions by shuttling proteins, mRNA, and microRNAs.

Junctional sarcoplasmic reticulum motility in adult mouse ventricular myocytes. [PDF]

, 2020
Excitation-contraction (EC) coupling is the coordinated process by which an action potential triggers cardiac myocyte contraction. EC coupling is initiated in dyads where the junctional sarcoplasmic reticulum (jSR) is in tight proximity to the sarcolemma

Subcellular heterogeneity of ryanodine receptor properties in ventricular myocytes with low T-tubule density [PDF]

, 2011
Rationale: In ventricular myocytes of large mammals, not all ryanodine receptor (RyR) clusters are associated with T-tubules (TTs); this fraction increases with cellular remodeling after myocardial infarction (MI).
