Calcineurin signalling mechanisms in myocardial hypertrophy
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 ...
متن کاملCyclosporin 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...
متن کاملBuckwheat 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...
متن کاملCalcineurin 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...
متن کاملCalcineurin/NFAT coupling participates in pathological, but not physiological, cardiac hypertrophy.
Calcineurin (PP2B) is a calcium/calmodulin-activated, serine-threonine phosphatase that transmits signals to the nucleus through the dephosphorylation and translocation of nuclear factor of activated T cell (NFAT) transcription factors. Whereas calcineurin-NFAT signaling has been implicated in regulating the hypertrophic growth of the myocardium, considerable controversy persists as to its role...
