Calcium dysregulation increases right ventricular outflow tract arrhythmogenesis in rabbit model of chronic kidney disease.

Journal of cellular and molecular medicine

Huang SY, Chen YC, Kao YH, Lu YY, Lin YK, Higa S, Chen SA, Chen YJ.
PMID: 34761510
J Cell Mol Med. 2021 Dec;25(24):11264-11277. doi: 10.1111/jcmm.17052. Epub 2021 Nov 10.

Chronic kidney disease (CKD) increases the risk of arrhythmia. The right ventricular outflow tract (RVOT) is a crucial site of ventricular tachycardia (VT) origination. We hypothesize that CKD increases RVOT arrhythmogenesis through its effects on calcium dysregulation. We analysed...

Oxytocin Protects Against Isoproterenol-Induced Cardiac Hypertrophy by Inhibiting PI3K/AKT Pathway via a lncRNA GAS5/miR-375-3p/KLF4-Dependent Mechanism.

Frontiers in pharmacology

Yang Y, Wang Z, Yao M, Xiong W, Wang J, Fang Y, Yang W, Jiang H, Song N, Liu L, Qian J.

Front Pharmacol. 2021 Dec 03;12:766024. doi: 10.3389/fphar.2021.766024. eCollection 2021.

Cardiac hypertrophy is caused by cardiac volume or pressure overload conditions and ultimately leads to contractile dysfunction and heart failure. Oxytocin (OT), an endocrine nonapeptide, has been identified as a cardiovascular homeostatic hormone with anti-hypertrophic effects. However, the underlying...

Myocardial Infarction After High-Dose Catecholamine Application-A Case Report From an Experimental Imaging Study.

Frontiers in cardiovascular medicine

Beyhoff N, Lohr D, Thiele A, Foryst-Ludwig A, Klopfleisch R, Schreiber LM, Kintscher U.

Front Cardiovasc Med. 2020 Nov 19;7:580296. doi: 10.3389/fcvm.2020.580296. eCollection 2020.

Although heart failure following myocardial infarction (MI) represents a major health burden, underlying microstructural and functional changes remain incompletely understood. Here, we report on a case of unexpected MI after treatment with the catecholamine isoproterenol in an experimental imaging...

MiRNA-339-5p promotes isoproterenol-induced cardiomyocyte hypertrophy by targeting VCP to activate the mTOR signaling.

Cell biology international

Cell Biol Int. 2021 Dec 02; doi: 10.1002/cbin.11731. Epub 2021 Dec 02.

MicroRNAs (miRNAs) regulate multiple biological processes and participate in various cardiovascular diseases. This study aims to investigate the role of miR-339-5p in cardiomyocyte hypertrophy and the involved mechanism. Neonatal rat cardiomyocytes (NRCMs) were cultured and stimulated with isoproterenol (ISO)....

Comparison of the effects of adenosine, isoproterenol and their combinations on pulmonary transit time in rats using contrast echocardiography.

Medical ultrasonography

PMID: 34379710
Med Ultrason. 2021 Aug 04; doi: 10.11152/mu-3088. Epub 2021 Aug 04.

AIMS: To compare the effects of adenosine (Ade), isoproterenol (Iso) and their combinations on pulmonary transit time (PTT) in rats using contrast echocardiography.MATERIAL AND METHODS: Thirty-two adult Sprague Dawley (SD) rats were divided into four groups (n=8) according the...

Segmental analysis by speckle-tracking echocardiography of the left ventricle response to isoproterenol in male and female mice.

PeerJ

Walsh-Wilkinson E, Arsenault M, Couet J.
PMID: 33763310
PeerJ. 2021 Mar 12;9:e11085. doi: 10.7717/peerj.11085. eCollection 2021.

We studied by conventional and speckle-tracking echocardiography, the response of the left ventricle (LV) to a three-week continuous infusion of isoproterenol (Iso), a non-specific beta-adrenergic receptor agonist in male and female C57Bl6/J mice. Before and after Iso (30 mg/kg/day),...
