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

open access: yes, 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

Hamartomas of mature cardiac myocytes [PDF]

open access: yesEuropean 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]

open access: yes, 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]

open access: yes, 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.

Calcium Signaling in Cardiac Myocytes [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2011
Calcium (Ca(2+)) is a critical regulator of cardiac myocyte function. Principally, Ca(2+) is the link between the electrical signals that pervade the heart and contraction of the myocytes to propel blood. In addition, Ca(2+) controls numerous other myocyte activities, including gene transcription.

Intense myocyte formation from cardiac stem cells in human cardiac hypertrophy [PDF]

open access: yes, 2003
It is generally believed that increase in adult contractile cardiac mass can be accomplished only by hypertrophy of existing myocytes. Documentation of myocardial regeneration in acute stress has challenged this dogma and led to the proposition that ...

Nuclear Calcium in Cardiac Myocytes [PDF]

open access: yesJournal of Cardiovascular Pharmacology, 2015
Calcium (Ca) is a universal second messenger involved in the regulation of various cellular processes, including electrical signaling, contraction, secretion, memory, gene transcription, and cell death. In heart, Ca governs cardiomyocyte contraction, is central in electrophysiological properties, and controls major signaling pathway implicated in gene ...

Paracrine Effects of FGF23 on the Heart

open access: yesFrontiers in Endocrinology, 2018
Fibroblast growth factor (FGF) 23 is a phosphaturic hormone primarily secreted by osteocytes to maintain phosphate and mineral homeostasis. In patients with and without chronic kidney disease, enhanced circulating FGF23 levels associate with pathologic ...

Ventricular androgenic-anabolic steroid-related remodeling: an immunohistochemical study [PDF]

open access: yes, 2017
Background: Several fatal cases of bodybuilders, following a myocardial infarction after long exposure to androgenicanabolic steroids (AAS), are reported. In recent years, evidence has emerged of cases of heart failure related to AAS consumption, with no

Silibinin Protects Against Isoproterenol-Induced Rat Cardiac Myocyte Injury Through Mitochondrial Pathway After Up-regulation of SIRT1

open access: yesJournal of Pharmacological Sciences, 2006
Terminally differentiated adult injured cardiac myocytes have been used for various animal models of heart failure. It has recently been shown that isoproterenol induces injury in rat neonatal cardiac myocytes via a β-adrenergic pathway, suggesting that ...
