چکیده

Calcineurin dephosphorylates multiple serine residues near the N terminus of NFAT proteins enabling them to translocate from cytoplasm to nucleus, where they activate a subset of hypertrophic response genes. Transgenic mice over-expressing a constitutively active form of calcineurin or NFAT3, developed obviously hypertrophy and heart failure or sudden death proving its pathogenic role. Here we used literatures on MEDLINE (2000-2011), systematically reviewed the new development of calcineurin signaling pathway in myocardial hypertrophy (J Geriatr Cardiol 2010; 7:189-192).

Buckwheat Rutin Inhibits AngII-induced Cardiomyocyte Hypertrophy via Blockade of CaN-dependent Signal Pathway

Buckwheat rutin has been found to be able to inhibit angiotensin II (AngII) - induced hypertrophy in cultured neonatal rat cardiomyocytes, but the mechanism remains uncertain. In this study, myocardial hypertrophy model was made by adding AngII to the medium of cardiac myocytes of neonatal rats, meanwhile, different concentrations of buckwheat rutin were applied to observe their effects. Intrac...

Expressions of CD11a, CD11b, and CD11c integrin proteins in rats with myocardial hypertrophy

Objective(s):To examine the expressions of CD11a, CD11b, and CD11c integrins in the myocardial tissues of rats with isoproterenol-induced myocardial hypertrophy. This study also provided morphological data to investigate the signal transduction mechanisms of myocardial hypertrophy and reverse it. Materials and Methods: A myocardial hypertrophy model was established by subcutaneously injecting i...

Cyclosporin A inhibits cardiac hypertrophy and enhances cardiac dysfunction during postinfarction failure in rats.

Calcineurin has recently been implicated as a mediator in the signaling pathways that transform intracellular calcium signals to the phenotype of myocardial hypertrophy. The present study was conducted to examine the effects of cyclosporin A (CsA), an inhibitor of calcineurin, on myocardial hypertrophy and remodeling during congestive heart failure (CHF) in rats. After ligation of the left coro...

Calcineurin in human heart hypertrophy.

BACKGROUND In animal models, increased signaling through the calcineurin pathway has been shown to be sufficient for the development of cardiac hypertrophy. Calcineurin activity has been reported to be elevated in the myocardium of patients with congestive heart failure. In contrast, few data are available about calcineurin activity in patients with pressure overload or cardiomyopathic hypertro...
